After that, Krune took out the book Flita had brought with her. It detailed all the information about the fish that collectors had documented. Quite a few rich households grew these fishes as decoration. With that, everyone had collated their information on online forums dedicated to this.

Unsurprisingly, one researcher delved into the topic fully, collating all the information available online before he experimented on his own collection, finally publishing the book. It was the most detailed among all the books relating to the topic.

It was what Krune had asked her to bring, wishing to understand everything that was to know about the fish he was dealing with. While the bone trees grew and the fish ate the powdered bone tree fruits, Krune read through the book, eventually finished reading after three days.

It was a considerably thick book detailing all the information he required. Once he read through them all, Krune could not help but smile devilishly as he muttered, "So, they grew better when the weather was colder? Consider that done."

Not long after, Krune dropped a chunk of ice in the second reservoir. He had condensed it using his Ocean Turbulence. Of course, he also imbued some of the healing effects in it. This was to ensure the fish wouldn't die due to unfortunate or unforeseen reasons.

This way, he planned to create the same situation as the Motor Fishes: cause them to brim with excess energy so that they would mate as many times as they were biologically capable of. This way, he could spur their growth faster, causing them to evolve further and further as the generations passed on.

Based on what was written in the book, this fish species laid eggs every five days. And each time, they laid around 20-30 eggs. It was a considerable sum that could quickly grow out of control when not taken care of.

It was then that Krune realized part of the reason why the octopuses traded the fishes with the human cities. Enough population of the fishes would be replenished almost daily, so no matter how much the human cities consumed them, their population would never go down.

'They might have some aquatic or coral species for the fishes to feed on and grow. That might form the core of this food chain,' Krune thought as he continued to work, dicing up the bone tree fruits into powder before dumping them into the second reservoir.

He also consumed a Tier 1 Essence every day. And when he checked on the weighing machine, he realized that he was indeed growing in weight by a single kilogram every day. He could also feel his strength increasing, achieving new limits every day.

To grow accustomed to his new strength, Krune used the training room, training whenever he didn't work on his project. Upon seeing his zealous activity of alternating between work and training, Flita was inspired.

She then controlled her strength to spar with him, finally realizing something. She was unable to defeat Krune. His defense was impeccable. No matter what she threw at him, he calmly defended against them.

Not only that, but at times when she failed to control her strength and leaked out a bit of her true strength, he still parried them, suffering minimal damage from the attacks. This made her realize that her opponent had a wealth of experience to read her like a book.

From there, she constantly trained with him, asking him for advice all the time, growing leaps and bounds in skill. She noticed that even though Krune's weight class was on the level of a Demon Child, he was capable of outputting all the strength his body could muster.

If she determined his ratio to be the norm and compared herself to it, she figured that she was only outputting less than forty percent of her body's potential. When she realized this in numerical terms, Flita was unable to believe herself, muttering in disbelief, "How?"

"If you live and fight long enough, this is possible." Krune smiled, guiding her in ways where she could better employ her body's strength and use her weight to greater advantage. He had lived for more than 230 years now, so his plethora of experience was only rising. Guiding a youngling like Flita was child's play for him.

'Hmm, teaching others is fun. Should I establish a sect in the God Realm once I leave this place? It seems fun. Once I gather my family, I'll probably do that. It would be a nice change of pace to settle down in a place and grow together as a family. Plus, I can also teach this body cultivation to everyone,' Krune thought, smiling as a result. But soon, he began to miss them, hurriedly eradicating the thoughts before he became homesick.

He had already struggled through a lot in controlling himself while living with the Seamstress. He lost count of the number of times when the mood between himself and her was perfect to bud romantic feelings and when both of them had almost given in. It took him all his might to extricate himself every single time.

If he wasn't as old or lacked enough experience, Krune would have crossed that boundary long ago. As a human and a mortal at that, he was aware of everything that happened around him. He wasn't an ignorant wisp in that regard.

That was why he faced numerous struggles while staying with the Seamstress. Naturally, he knew very well for a fact that if the Seamstress made a move on him right now, he would give her zero resistance. She had already made her way through her emotional barriers.

Similarly, if Krune did the same to the Seamstress, she would give him zero resistance as well. If both of them hadn't controlled themselves, they might have had a child by now. Thankfully for Krune, he didn't do anything that might make him live a life of guilt. 'I should be careful when I meet the Seamstress in the God Realm. I can't do anything that might make Feifei kill me.'

Days passed in such a fashion as Krune's weight continued to increase. Soon, he crossed 150 kilograms, reaching the status of a Tier 1 human.
