Ross turned and walked outside the laboratory and saw Robin standing alone in the corner with her eyes lowered and her expressions were a little lonely.

Taking a look at her, Ross walked over and after being silent for a moment, he said:

"Pudding's Memo-Memo Fruit can delete and change memories. If you want, you can forget about that bad pasts."

Robin raised her head and her eyes flashed with light but that light disappear in the next moment, a slight smile appeared on her face and she said, "Some things can't be forgotten…"

"Yes."

Ross smiled gently.

For whatever bad things had happened, forgetting is tantamount to escaping. This is a manifestation of being not strong enough. A person with a strong heart will not choose to forget anything, nor will that person be entangled in the body and bruises, but they will train and their Spirit will not be broken.

Robin's heart is undoubtedly strong. Maybe there are some occasional thoughts about forgetting her past but those thoughts will be wiped out instantly. If her heart wasn't strong enough, she may have died in O'hara, or died on some island and would not have survived until now.

No doubt.

Ross also didn't want to see Robin make a weak choice.

Just as Ross and Robin left the laboratory and were about to leave the base, the Den Den Mus.h.i.+ on Robin suddenly rang.

Purupurupuru !!

Den Den Mus.h.i.+'s voice sounded Buzz! Buzz! Rustling, Robin took out the Den Den Mus.h.i.+ and connected, and from the other side of Den Den Mus.h.i.+ came the solemn voice of Kaku.

"Captain Robin."

"We found the World Government's hidden base of the scientific force!"

Among the World Government subordinates, in addition to Marine and CP0, there are organizations of various sizes such as the Science Force among various other forces and it is that same Science Force that Ross cares about.

Because the method of "Eating" Devil Fruit by weapons and creating weapons like Devil Fruit Swords is one of the research achievements done by the top scientist in the scientific Force, Vegapunk.

Using Devil Fruit to create weapons with the Devil Fruit powers, this is one of the technologies that Ross needs because after getting the Soul-Soul Fruit, he plans to inject the ability of Soul-Soul Fruit into one of the 12 Saijō Ō Wazamono Swords, Cursed Blade Murasame to make a 'Soul Slayer Blade'.

But.

It appears in Ross's memory that all Devil Fruit eaten by all weapons were Zoan Fruits. The Soul-Soul Fruit belongs to Paramecia Type. It is still unknown whether it can still be used for weapons.

In any case, he needs this technology.

"The Scientific Force Hidden base … how did you find it?" Ross heard Kaku's report and paused slightly before speaking in the Den Den Mus.h.i.+.

Kaku was not surprised that Ross was next to Robin and he responded in a deep voice:

"f.u.kuro was caught by Marines and was sent to the secret scientific base and he sent us some information."

Ross frowned when he heard that f.u.kuro was captured. "f.u.kuro was captured? When did this happen?"

"Three days ago."

Kaku responded in a low voice: "I thought we could deal with it, and after tracing him, we found that it was the Secret Scientific Base of the World Government so I can only report to you."

At first, Kaku and others didn't intend to alarm Ross. They thought that f.u.kuro had only been discovered by Marine, and they had to find a chance to rescue him. However, he was taken to the Secret Scientific Base.

Ross asked in a deep voice: "Is he alive?"

"Unclear, the Vivre Card is acting weird now."

Kaku responded with a low tone. He had f.u.kuro's Vivre Card in his palm. This Vivre Card did not burn, but it was strangely static and did not move in a certain direction.

It was as if Vivre Card's perception was blocked by some force.

Ross paused with his eyes flickering and said after some time. "So it's no longer possible for us to use the Vivre Card to locate the Hidden Scientific Base?"

"Yes."

Kaku nodded and said: "However, the Vivre Card is still pointing in a general direction, as long as the Scientific Base does not move, we should be able to find it according to the direction."

Ross rubbed his eyebrows.

Kaku doesn't have to say it as Ross had already considered this possibility, the Hidden Secret Scientific Base may really have the ability to move around, just like Zou Island carried on the back by the ancient giant elephant.

But whether it's moves or not, he has to take a trip.

"Explain the direction and circ.u.mstances."

Ross took the Den Den Mus.h.i.+ from Robin. First, he asked Kaku to report the situation in detail and at the same time, he said to Robin, "Robin, call Laffitte, Law, Ficheux Erman, and tell them to prepare for action."

Robin responded and immediately notified Laffitte and others.

Since the Ghost Hand Pirate regiment is now a huge power that owns Totto Land sea, its every move is highly watched by various powers of the World. If the Giant Corps is moved too loudly, Marines and World Government will likely to act against them causing unnecessary trouble.

As for Laffitte, Law, and others, Laffitte's hypnotic ability is needed when understanding information. Law's Surgeon-Surgeon Fruit s.p.a.ce ability will also play a huge role. Ficheux Erman's speed is fast enough, and his flexibility can be considered as a guarantee for solving various accidents.

Although the Scientific Base is mysterious but no matter how mysterious, they cannot possess the world's top combat power. They would not be able to handle the current Ross. Once they are found, they will be destroyed.

If it weren't for the fact that Ross wasn't just out to destroy, but to get the Devil Fruit technology to use for weapons, and whatever else might be useful, he wouldn't have a problem going there alone by himself.

Quickly.

Ross learned specific information from Kaku. On a simple sea map, he roughly drew several moving tracks of Vivre card and calculated the sea according to time.

Because Vivre Card's direction is now blocked by something, Vivre Card cannot accurately locate the Scientific Base, but Ross can still shrink to a sea area.

However.

In that sea area, there is no marked island!

"Sure enough there are no islands…"

Ross's eyes flicker slightly, which means that the Secret Base is not an island that can be reached by Log Pose and whether it is an island or not is still up for debate.

This is not surprising for Ross.

There are a lot more people who would want to find a place like the Science Base with its artificial Devil Fruit technology, which exists in the Science Base, once it can be located on an established island, Kaido would have attacked it first.

Therefore, the base of the Scientific force must be on an island without magnetic force or magnetic disorder, which will not be captured by Log Pose.

Or … it may simply be a mobile super-large s.h.i.+p, like the terrifying Thriller Bark of Gekko Moria which was similar to the size of an island.

"The Scientific Force Base of the World Government … eh."

"Since those guys captured one of ours, we really can't just ignore them, but just us?"

Ficheux Erman and Laffitte and others arrived one after another on the coast of the Cake Island.

A medium-sized sailing s.h.i.+p is docked here.

For this team of the Ghost-Hand Pirate regiment, the size of the s.h.i.+p, artillery, and even speed are not significant.

Once enemy s.h.i.+ps appeared in their area of ​​sight, Ross could easily control the current and pursue at a speed much faster than any s.h.i.+p in this world.

"Five people is enough."

Ross calmly responded to Ficheux Erman and then motioned Laffitte to come and study the sea map and described the specific situation to Laffitte.

Laffitte's current level of navigation is much higher than Ross's. Soon, the range of the sea marked by Ross is narrowed again.

"If the base of the Scientific Force Base will move, the sea range will be even greater, but even if such a base can move, the speed will not be very fast. It may still be possible for us to find it based on this sea."

Laffitte held a pen to mark on the sea map.

Ross took a closer look at Laffitte's narrowing sea range. A small half of this sea was inside the Calm Belt, and the other part was in the second half of the Grand Line, on the edge of New World.

"What if we narrow it down to the inner part of the Calm Belt?"

Ross spoke suddenly.

Laffitte was trying to say that Calm Belt could be ruled out, but when he heard Ross, he suddenly looked thoughtful.

It is not impossible.

Calm Belt is the home of the Sea Kings and there are countless giant Sea Kings in it. There are some Sea Kings which are too large that they can be compared with the Giant Elephant Zhunisha. Even the Disasters can be killed by just their casual attack and it is too dangerous.

But it is also because of its danger that Scientific Force Base may have a method that can be used by them to built an artificial island in the Calm Belt. After all, Seastone is embedded in the bottom of the Battles.h.i.+ps to blind the Sea King's perception, which was researched by Scientific Force Base.

"If that's the case, the scope becomes even smaller."

Laffitte pondered before responding.

Ross nodded and glanced at the few people present, and said, "It's not too late, let's go now and find this secret Scientific Force Base."

Including Ross, there were five people on board.

Ross, Robin, Trafalgar Law, Laffitte, and Ficheux Erman, except for these five, they only have some obedient toys that obey orders.

Currently, Totto Landsea has established a rough governance system. Even if Ross is not there, it will not be a big deal, not to mention Fujitora, s.h.i.+liew of the Rain, and Hajrudin are still there.

How to transform the Cursed Blade Murasame into a 'Soul Blade', Ross needs to get that technology for his plans!

The entire group quietly left the Cake Island and Totto Landsea and sailed towards the edge of the Grand Line, near the Calm Belt.

Because this time they were light-loaded and they were traveling on a medium-sized sailing s.h.i.+p with only four people, they did not alarm any forces. According to the information that the forces received, Ross and Robin usually lived in the Sky Island Birka and rarely come down so even the World Government did not notice Ross's actions.

After a few days.

With Ross manipulating the current at full speed, the s.h.i.+p sailed across New World to the edge of it and came near the Calm Belt.

The two seas, Calm Belt and Grand Line, can be described as clear and distinct. On one side, the current is turbulent and the sea breeze is whistling. On the other, the sea surface is calm, without any wind and waves.

It's like two trains crossing each other, with a very clear dividing line.

"Calm Belt …"

"Boss, are we really going in?"

Ficheux Erman didn't seem to have any good memories of Calm Belt. Looking at Calm Belt in front of him, his mouth twitched slightly as he revealed an expression that said that he didn't really want to go in.

Ross is not afraid of the huge Sea King, which is the size of an island, but he will still get a little irritated if they continue to attack.

"Ho ho ho, you look a little scared."

Laffitte stood aside and smiled, showing an expression that looked through Ficheux Erman's mentality.

Ficheux Erman's eyes flickered and he retorted: "I'm kidding. Calm Belt, isn't it just a home for a little bigger Sea Kings?"

Ross didn't care about Ficheux Erman's words. He stood at the forefront of the deck, stepped on the guardrail and the power of distortion controlled the current underneath the s.h.i.+p and it rushed forward with the sailboat and he broke into the Calm Belt.

Before he escaped from Impel Down, Calm Belt still have the ability to threaten him, but today, even if he is faced with a Sea King as big as an Island, there will be no trouble.

Cras.h.!.+

Almost as soon as the s.h.i.+p broke into the Calm Belt sea and sailed less than a few kilometers, a Sea King with a length of hundreds of meters poked its head out and looked at Ross's s.h.i.+p.

This Sea King can only be regarded as a small Sea King in this sea. After staring at the s.h.i.+p with its two eyes, it treated the s.h.i.+p as a snack and opened its mouth showing rows of sharp teeth, and snapped it.

But.

Almost at this moment, a magnificent momentum pa.s.sed by instantly.

"Roll Out."

Ross glanced indifferently at the Sea King and he controlled the current to pa.s.s by it.

The Sea King was under the shock of Ross's 'HaoshokuHaki. Although it did not fell unconscious, it still showed a humanized expression of fear. It watched Ross' s.h.i.+p pa.s.sing by, and finally dived into the sea and disappeared.

Ross's HaoshokuHaki can have an instant deterrent effect on small and medium-sized Sea Kings, but the effect on large Sea Kings will not be obvious enough, let alone the giant Sea Kings.

But.

The moment he entered the Calm Belt, Ross entered the state of Spirit Heart and he fully used Observation Haki and inspired the ability of Future Prediction.

Once a large Sea King or a Super Giant Sea King which can attack the s.h.i.+p appears, he will be able to predict it seven seconds in advance and he will be able to completely avoid them.

Sailing down this road can be described as safe.

Although from time to time, outrageous Sea Kings emerge from the sea, they never managed to get a hold of Ross's s.h.i.+p.

So.

Ross controlled the s.h.i.+p in this way and swept back and forth a few times around the marked sea area but he did not see anything like an island or the existence of a large s.h.i.+p.

Laffitte stood at the table covered with sea maps, his face reflective and thoughtful.

Trafalgar Law, sitting next to Kikoku the demon sword, said, "We have been here for a few days. If that base moves, then maybe it's not in this sea anymore."

"The Vivre Card doesn't work, and it doesn't know the direction of that base's movement. The search range will greatly increase. In this case, even if we are fast enough, it will be difficult to find."

Laffitte said in a difficult way.

Just then, Ross came over from one side, glanced at the sea map and the mark made by Laffitte, and said, "What if it was underwater?"

Impel Down is also built on the bottom of the Calm Belt, but only part of it is exposed on the surface. The government has no doubt the ability to build a building on the bottom of the Calm Belt.

"Underwater? It's not impossible …"

Laffitte points to the ground with his wooden staff which gave a few beeps as he said, "But in this case, we need to go underwater to find them. Even if Captain can take the s.h.i.+p into the water, it is still too dangerous in a place like Calm Belt. "

All the people present here were Devil Fruit Users. If they went into the sea and encounter a giant Sea King who attacked them and they were washed away by the seawater, they will all be finished.

A Yonkō (Four Emperors) died in the sea by drowning in it, that would probably be the biggest joke of the century.

"Anyway."

Ross glanced slightly, and said, "I will not be in any danger if I am alone. You go outside the Calm Belt and wait."

Protecting a s.h.i.+p on the under-floor of the Calm Belt where the Sea Kings roam is very difficult, even for Ross, but if he is alone, there will be no problem.

The seafloor of the Calm Belt is very deep.

Because there are large and even supergiant Sea Kings here, the average depth can be described as the deepest sea in the entire world, and in this deep water, Ross is sneaking alone.

Thanks to the ability of Light Distortion, Ross can still see far ahead even in the deep sea where there is nothing but darkness, not to mention that his Observation Haki can also be used in the sea.

Although Ross's Observation Haki does not have the same kind of effect that Hajrudin's does where he relies on Rumble-Rumble Fruit to expand the range to a great extent but there is no problem in covering three to four kilometers.

That is.

Ross's search range is a ball with a diameter of 3-4 kilometers centered on himself.

"This is the bottom of the sea …"

After sinking to unknown depths, Ross landed on the ocean floor, which he estimated to be at least a few tens of thousands of meters deep.

The mud on the seafloor is silent and unmoving, the whole seafloor looked dead, no one has reached this place for thousands of years.

Ross didn't stop at the bottom of the sea and he quickly floated a few kilometers and then began a carpet search.

His movement speed on the ocean floor is not slow. Occasionally, he will encounter the supergiant Sea King, but because Ross 's body is too small for the supergiant Sea King, he is not even as big as their single hair, so he will not be noticed.

One hour……

Two hours …

Three hours……

As time goes by, Ross searches continuously on the bottom of the Calm Belt, but he still found nothing. The most he sees are those Sea Kings swimming around.

And just as Ross was wondering if he had made a mistake and the Secret Base was not here just as Laffitte had expected, he sensed something strange ahead.

Sneer! Sneer! Sneer!

A Sea King, nearly a kilometer in size, was swimming by when all of a sudden its body split and was torn to pieces and then dragged away by something.

Ross blinked and immediately followed.

The Sea King is cut into pieces of meat by some kind of mechanical thing. It looked a bit like a rough version of a large Pacifista.

"The first generation of Pacifista?"

There was a hint of thought in Ross' eyes.

It is not laser power that cuts the Sea King into pieces of meat but a special kind of silk thread. It seems to have a strong tenacity, comparable to the thread fruit capability of Doflamingo. The head of the Sea King b.u.mps into the silk thread and cuts itself into pieces.

Following this weird machine, Ross sneaked under the sea and finally came to a base hidden deep in the mountains below the sea.

This can be regarded as a bulging mountain range on the bottom of the sea, which is extremely wide in Ross's perception. Due to the darkness, it is even difficult to see the overall appearance.

This position should not reach a depth of 10,000 meters from the sea surface.

Silence.

Ross followed the weird machinery that dragged a lot of meat into the interior of the mountain, through a strange cave, to a gate made of steel.

A cursory glance revealed the World Government logo on the door, while in one corner was the Scientific Force Base number zero was written.

"Base Zero …"

Ross watched the door open and watched as the machine dragged the pieces of meat into the base with a wistful look.

There are probably more than one Scientific Force Base, and this one is probably the most secretive of them all, hidden deep under the Calm Belt.

Without making a sound.

Ross used his Distortion s.p.a.ce and Distortion Sound abilities and sneaked into the door as soon as the door closed.

The inside and outside of the base are very different.

Outside is a quiet mountain range, and in the dark, without any light, full of ancient and desolate, but inside the base, everything suddenly became a scene taken out of a sci-fi movie.

The white lights are inlaid on the ceiling, making the entire base bright. The entire base seems to be made of some extremely strong ore, most of which is second only to Seastone.

"Number Nine is back."

"The meat looks pretty good this time."

Two people wearing World Government Scientific Force Base uniforms stepped out and watched the huge machine pull the pieces of meat over with a smile on their faces.

And just as they inspected the pieces of meat, one of them looked stunned and he felt weird for some reason and he said to his companion:

"Did you feel … anything pa.s.ses by us?"

"There's nothing there."

His companion glanced around strangely and smirked: "Are you not sleeping well these two days? This is the bottom of the Calm Belt!"

"Well, it should be my Misconception."

The man also shook his head, thinking that this is the bottom of the Calm Belt sea and it is needless to say that there are Sea Kings everywhere. Except for the submarines designed by Vegapunk that can reach here, this place is almost isolated from the rest of the world.

Secret Base Center.

In one of the deepest laboratories, there are a lot of strange peoples, they seemed to be human but they have animal arms or teeth.

Some even have half of their body as some kind of crustacean, while the other half of their body looks like a mix between lion and tiger and looks extremely scary.

"Biological modification … Is this the end?"

Vegapunk held up the reports, frowning.

This is not a base for making the mechanical transformation, nor is it a place for making artificial Devil Fruit, but it is the Base Zero used for biological transformation.

In fact, artificial Devil Fruit also originated from here, and SAD that is used for making an artificial Devil Fruit is also an important raw material for biological transformation.

"Whew, but it's now possible to create Artificial Devil Fruit! Why bypa.s.s Devil Fruit to directly transform it! If we make Artificial Devil Fruits, we will have an unlimited army of people."

Caesar stands beside Vegapunk with his arms outstretched and an excited smile on his face.

Vegapunk dropped the file and said:

"Artificial Devil Fruit … My original intention was to detach the Devil Fruit and get straight to the essence of its life, but are you going back to the Devil Fruit again?"

"What are you talking about? It's …"

"Don't mention it again."

Vegapunk continued to look down at the file.

Caesar's face changed for a while and he was feeling very annoyed and he quips: "But the only thing you can test now as a semi-finished product is that Marine Vice-Admiral."

"No."

Vegapunk turned the file to the last page and narrowed his eyes. "His inner will is beyond my imagination. It can't be said to be a semi-finished product anymore, it can be regarded as the only finished product!"

"Your transformation was successful?"

Caesar's eyes widened instantly.

The experimental bodies they can capture here are basically not very strong. Occasionally, some strong ones are caught and once they are transformed, their bodies will reject the transformation and they will even lose all the desire to survive in the process of transformation. Eventually, all the experiments failed.

But just a while ago, a Marine Headquarters Vice-Admiral volunteered to partic.i.p.ate in the transformation, and in the process of transformation, he displayed a strong will and desire to survive, supporting two consecutive transformations!

There are three rounds of Vegapunk transformation, which are divided into three stages. Now it seems that the third round of transformation has also succeeded!
