Dugu Mo dropped all the mineral bottles he was carrying onto the ground as he seized the gourd from Ling Yun's hands.

Ling Yun didn't dodge and simply allowed him to do so as he waited to watch him make a fool of himself.

"Aiya!" Once the gourd was in his hands, Dugu Mo felt as though he was carrying a thousand-kilogram copper cauldron. It was so heavy that his arms suddenly sank and he almost fell on his face!

Dugu Mo hurriedly responded by grabbing the gourd tightly with his right hand as he held onto the bottom of the gourd with his left hand. At the same time, his right leg extended forward, which was enough to prevent him from falling.

His facial expression changed as he exclaimed, "So heavy!"

The gourd, which contained all of the dragon saliva, was at least 1000kg!

Ling Yun was so amused by what he saw that he couldn't stop laughing. He pointed forward to the empty stone pond as he said, "Greedy pig, why don't you use your brain for a moment? This pond is so huge, so even if it was filled with mere water, it would weigh at least 500kg, let alone dragon saliva!"

At the same volume, dragon saliva was at least twice as heavy as water. With such a huge pond of dragon saliva contained in the gourd, how can it be light?

Dugu Mo clenched his teeth for a while as his face turned increasingly red. Eventually, he was no longer able to take it as he bent over to place the gourd on the ground. He took in deep breaths as he spoke. "I don't understand how you carried such a heavy item as though it were a plaything. Isn't your strength a little too terrifying?"

Even before Ling Yun attained Physique Tempering Stage Four, his strength with a single arm had already exceeded 500kg. Now that he had broken through Physique Tempering Stage Four and completed his Yin-Yang harmony balance, his Kung Fu had improved tremendously. His strength would naturally be astonis.h.i.+ng as well!

Ling Yun chuckled as he lifted his hand to carry the gourd. Following that, he activated his spiritual will to store the gourd into his spatial ring.

Ling Yun knew that the gourd was an impressive treasure. He was unable to make full use of the gourd's magic now, but once he figured out how to use the gourd, he would be able to store as much dragon saliva as he wanted.

Presently, he was only able to make use of the natural s.p.a.ce of the gourd and not its magical power.

One example would be Ling Yun's spatial ring. Once he placed the fully filled gourd into his spatial ring, he wouldn't be able to feel its weight. This was the magical power of the spatial ring. Regardless of how many items he put in, he wouldn't be able to feel any weight.

This was because the s.p.a.ce inside the spatial ring was a totally different and independent dimension. Because the s.p.a.ce didn't belong to Earth, everything inside the spatial ring wouldn't be affected by Earth's gravity.

Of course, the spatial ring itself was still under the influence of Earth's gravity, so the ring on Ling Yun's hand still had its own weight. This was truly extremely mysterious and magical.

Dugu Mo finally caught his breath as he circled around Ling Yun a few times. He sized Ling Yun up as though a peony flower was growing on Ling Yun.

"I mean… How did the entire pond of dragon saliva fit inside your gourd? Is this also a secret treasure of your Immortal Physician Sect?"

The amount of shock Ling Yun brought Dugu Mo was way too much. It was as though Ling Yun was toppling mountains and overturning the seas one after the other. This was simply too much for his brain.

Ling Yun didn't bother with him as he stared seriously at the empty pond. He squinted his eyes as he suddenly revealed a different expression.

"Why? We've drained the entire pond of dragon saliva, so why are we not leaving? Why are you staring blankly at the pond?" Dugu Mo was puzzled as he followed Ling Yun's eyes and looked at the pond too.

They were naturally not able to empty the entire pond completely using a gourd. Therefore, there was naturally still a thin layer of dragon saliva at the bottom of the pond. However, this thin layer of dragon saliva was not enough to obstruct Ling Yun and Dugu Mo's sharp eyes.

"Eh? The bottom of the pond seems to be…" Dugu Mo's eyes lit up as his jaw dropped once more. He pointed to the pond, and his lips trembled as he said, "This… Why does this look like a diagram of the Tai Chi Eight Trigram?"

Ling Yun jumped up and immediately arrived at the edge of the pond. This time, he placed two Fire Talismans by the periphery of the pond and chanted the incarnation. Two basketball-sized flames instantly started burning, which lit up the entire pond.

Earlier on, Ling Yun was too busy being shocked that the gourd could contain the entire pond worth of dragon saliva to notice anything else. Now that he noticed something strange, he was naturally going to uncover that mystery.

"Oh… What is this treasure? Why does your Immortal Physician Sect have so many unique items?" The pitiful Dugu Mo was once again dazed by Ling Yun's plaything.

Shock… He only needed to be shocked a few more times before getting used to it…

The circular shape at the bottom of the pond was created using natural resources. It was carved out using a rock from this cave.

There were no words at the bottom of the pond, only simple horizontal lines to mark out the eight symbols "Qian, Kun, Zhen, Xun, Kan, Li, Gen, Dui". On the inside was a Tai Chi diagram formed by Yin Yang fish. Separating the Eye of Yin and Eye of Yang was a dragon-shaped curve. The circular-shaped Eye of Yin and Eye of Yang were symmetrical around the dragon-shaped curve.

It was simple, unadorned, and crude, but it contained a mysterious Dao spirituality. This was a perfect diagram of the Tai Chi Eight Trigram!

Ling Yun's mouth twitched vigorously as his heart was filled with astonishment and delight. The emotions in his heart exceeded what he could express on his face.

If it wasn't for this magical gourd, he could have simply filled up some mineral bottles worth of dragon saliva before leaving with Little White and Dugu Mo.

In that case, he would never have been able to see what the bottom of the pond looked like with the depth of the dragon saliva reaching over half a meter.

Before leaving, Ling Yun thought of the heavily injured giant dragon. He felt bad and wanted to pour out some dragon saliva to leave it for the dragon to use. If it wasn't for this thought, he wouldn't have taken a second look at the pond.

After the fire extinguished, Ling Yun took out a few more Fire Talismans to use. He stared at the Tai Chi Eight Trigrams for a while before lifting his head to look at the three stone doors.

He almost let a great opportunity with the three stone doors slip by! Just almost!

Ling Yun's guess was that the Eight Trigrams was related to the three stone doors. However, he still required further a.n.a.lysis.

"Hey, genius from the Immortal Physician Sect! Did you manage to figure anything out? My Earth Emperor's Book is definitely here!" Dugu Mo was extremely spirited as both his legs were trembling with excitement.

"Quit disturbing me!" Ling Yun rolled his eyes at him as he continued to look at the bottom of the pond. He was thinking really hard.

Ling Yun recognized the next path to follow as he pointed at the Eye of Yin of the Yin Yang fish. He was convinced that this was the Eye of the Yang Spell from the Yin Yang Dragon Lock Spell. He then pointed to the Eye of Yang and understood that this was the Eye of the Yin Spell from the Yin Yang Dragon Lock Spell.

The dragon-shaped curve in the middle of the Yin Yang fish was naturally the tomb pa.s.sage he went in after leaving the Eye of the Yang Spell.

However, why are they reversed? Ling Yun furrowed his brows.

Ling Yun didn't even turn his head as he told Dugu Mo, "Examine everything and take care of Little White." After saying that, he jumped right into the pond.

When Ling Yun landed, he cautiously touched the symbols of the ma.s.sive Eight Trigrams. However, nothing happened.

This is the only place then… Ling Yun looked at the protruding circles of the Eye of Yin and Eye of Yang. They looked like two stone b.u.t.tons.

"Are you afraid of death?" Ling Yun turned back as he asked the spirited Dugu Mo.

Dugu Mo knew that Ling Yun must have figured out the key, and with his exceptional spirit, he answered without hesitation and with a lot of excitement, "Why would I be here if I was afraid of death?"

Ling Yun smiled as he replied, "If I'm not wrong, the two stone b.u.t.tons of the Eye of Yin and Eye of Yang should be the key to destroying this Yin Yang Dragon Lock Spell. Of course, it could also be the key to activating the ultimate killing spell. If it's the former, we will have a real chance of obtaining the greatest treasure here. If it is the latter, we will definitely die here. We can forget about escaping this place alive!"

Dugu Mo fell silent for a while before asking, "How confident are you?" Even though he said that he wasn't afraid of death, how could it possibly be true? At the crucial moment, he couldn't help but ask.

Ling Yun shook his head and gave a bitter smile. "The directions of this Yin Yang Fish and the Yin Yang Dragon Lock Spell are completely opposite. Therefore, this is really unpredictable. Moreover, we might even activate a whole new spell, which might be completely out of our control…"

Dugu Mo chuckled and asked, "And what do you intend to do?"

Ling Yun replied, "Since I saw it, I won't be able to sleep tonight if I don't try. Therefore, I am definitely giving it a shot! If you don't wish to gamble, you can leave now. You should be familiar with the way out. I'll give you six hours to leave this place. Six hours later, I'll activate this mechanism!"

Dugu Mo laughed out loud. "Ling Yun, you're truly belittling me. If you dare to try, wouldn't I be an embarra.s.sment to the Dugu Family if I ran away now? Moreover, if it wasn't for you, I would have been dead by now. So what do I have to fear?"

"Additionally, even if death is truly upon us, I will have absolutely no regrets being able to die with you! We can go to Yama, King of h.e.l.l, and have a sparring match!"

Ling Yun smiled as he looked over at Little White. All he saw was Little White's resolute eyes staring at him, which had no intention of leaving at all. Therefore, he nodded towards Little White.

"I'm going to activate it now!"

Dugu Mo and Little White's eyes quickly turned to the Eight Trigrams at the bottom of the pond, and they couldn't afford to blink. They were so nervous that their breathing almost stopped.

Ling Yun squatted down as both his left and right hands held onto the two stone b.u.t.tons before giving it a slight twist.

No movement! Ling Yun increased his strength, but he was still unable to move it!

This shouldn't be the case… Why won't they move? Ling Yun let go as he stared helplessly at the Tai Chi diagram. He was pondering in his heart if the diagram was simply there because some spell master decided to carve it there for fun.

Perhaps it's the direction! Let me try turning it the other way!

Ling Yun changed his body position as his left and right hand held onto the different b.u.t.tons now. He used strength, but it was still unmovable!

Ling Yun was getting a little fl.u.s.tered as his tough temperament came out.

I don't believe it!

Ling Yun's eyes looked extremely determined as both his hands held onto the stone b.u.t.tons once more. He used all of his force to execute his Yin-Yang harmony balance!

At that moment, Ling Yun suddenly felt his energy center rotating like crazy! The energy of Yin and Yang within his body started rising dramatically. The Yin energy flowed into his governor meridian, and it only took an instant for it to reach his arms. Following that, it surged towards turning the Yin and Yang stone b.u.t.tons!

Concurrently, Dugu Mo and Little White shockingly witnessed that Ling Yun started rotating in the middle of the Yin Yang Fish, and the speed of rotation was increasingly fast!

Simultaneously, a deep and desolate energy surged out from one of the three stone doors as it filled up the entire area. The sound was almost as clear as a bell, and it seemed to have crossed s.p.a.ce-time into the minds of each of them!

The Tai Chi Eight Trigrams at the bottom of the pond started sparkling with brilliance, the crude rocks turning sparkling and translucent. The symbols carved into it started flickering with rays of light, and the entire bottom of the pond was emitting brilliant radiance!

Ling Yun's body started rotating quicker and quicker until even Dugu Mo's eyes weren't able to capture him clearly.

"Kacha kacha…"

The rocks at the bottom of the pond started cracking, and a brilliant ray of light emerged from it. The carved symbols seemed to have been given life as they charged out and started floating in mid-air.

Countless traditional words started appearing on the roof of the cave and the surrounding walls. Every traditional word was sparkling in the air as though they were created by casting molten iron — filled with the gloss and realism of metal.

In the very next moment, the entire cave seemed to have disappeared and turned into a vast and abstruse universe. The Sun, the Moon, and countless stars appeared above everyone's head, and the entire cave was s.h.i.+ning magnificently!

This was different from the white fog in a killing spell, this was true radiance! It was so dazzling that people could faint from it. Shortly after, Dugu Mo and Little White really did faint and fall to the ground!

Under the sparkles of the Sun, the Moon, and countless stars, Ling Yun's rotating self instantly lit up splendidly as well.

Stellar Condensation Technique!

Under the brilliance of the white light, the countless traditional words were dazzling in the sky… They could be said to be dancing within the boundless universe as they started charging into Ling Yun's sea of consciousness one after the other!

When the last traditional word entered Ling Yun's forehead — "Woosh woosh woosh…" — the three stone doors opened concurrently, and endless immortal rays started illuminating the area.

Presently, Ling Yun's hands had already left the two stone b.u.t.tons as he stood up.

His s.h.i.+rt was torn beyond recognition, with some parts having turned into dust. He was naked and floating in what used to be the pond but now seemed like the vast and boundless universe. He looked like a G.o.d who existed throughout all of time!

"Woos.h.!.+" Without notice, the Emperor Brush had already emerged from Ling Yun's spatial ring, and there was a surge of spiritual energy. The brush grew big before multi-colored radiance started circulating around its shaft. It was glistening, dazzling, earth-shaking, and dominant!

The Emperor Brush grew so big that it stood straight between Heaven and Earth and was even able to support both Heaven and Earth! Following that, the Emperor Brush shrunk to become extremely small as it made its way into the sea of consciousness in Ling Yun's forehead and disappeared!

At almost the same time, a ma.s.sive old looking book shot out from the center stone door. The material was neither gold nor jade, neither copper nor stone, yet it contained majestic multi-colored spiritual energy. It surrounded and circled Ling Yun for a long time before disappearing in an instant, going into Ling Yun's energy center.

Earth Emperor's Book!

Ling Yun could clearly see, or more specifically, feel everything. However, he wasn't bothered by any of it. All he did was listen clearly to the voice of the ancient sage that sounded like a resounding bell!

"It is the way of heaven to take from what is in excess in order to make good what is deficient… Dao begets One — reason of being. One begets Two — Yin and Yang. Two begets Three — Heaven, Earth, and Man. Three begets all things…"
