At Tier 1, Krune felt that he had indeed grown a lot stronger. Not only was his physique the same size as usual, but his external appearance also didn't change. But internally, it was completely different. His density had definitely increased. His muscles had grown tougher to wield all his weight, making him stronger, faster, and tougher.

Even his skin was a lot stronger now. Krune felt happy that he was able to grow once again. Nevertheless, the greatest of this boon was the fact that all his abilities had grown stronger as well. It was like their effect had grown as potent as the density of his body did. Of course, that effect also applied to his Ocean Heart.

Krune noticed that even though he was eating the same amount of food, as usual, the increase in brightness of the crimson rings in his Ocean Heart was becoming slower and slower with each passing day.

This meant that its capacity was increasing. In turn, the quality of energy stored in them was also increasing. This meant that he would be able to store even more energy in them and use his abilities for longer durations.

While using his Sonic Radar, Krune noticed that its range and sensitivity had increased, allowing him to capture things that happened farther away than usual with greater clarity. Naturally, this effect was clearly pronounced while activating Ocean Turbulence. Krune was able to figure out just how much his abilities had grown stronger.

And that wasn't all. The best out of all this was the fact that the development effect of his Ocean Heart was absorbing the effect of the Tier 1 Essence, upgrading itself. Now, even without a Tier 1 Essence, Krune was able to strengthen himself to the limit of Tier 1.

Then again, since directly consuming a Tier 1 Essence was faster, he continued to use it while allowing his energy to recover so that he could finish healing Wrister first.

Ten days later, Krune gazed at the 12th generation of fishes in the second reservoir, finally noticing that some of the fishes seemed different from the rest. They were violet in color as compared to the usual white.

They weren't that different physique-wise, only spanning a couple of centimeters longer. However, the energy of their flesh was denser, not to mention their weight. They were indeed heavier. Krune was surprised by the development as he thought, 'Based on the color code, they match the demons. Then, would a blue fish appear next?'

Krune was curious as he continued to feed them. As a new generation was birthed after every five days, the number of violet fishes continued to increase in number. Moreover, even the white fishes had more energy in their bodies due to the constant breeding.

After all, the feed to the bone trees was their bodies crushed into a paste. And it was that the bone trees concentrated in their fruits. Without surprise, such a variable caused their essence to pile up more and more in the bodies of the fishes as they only consumed the bone tree fruit powder.

Thanks to his experience on Layer 3, Krune could instinctively feel that he wouldn't ever obtain any passive ability from these fishes, no matter how much they grew. 'So, they are in line with Layer 2. The concept of passive and active abilities don't exist here.'

'Well, I'm fine with that. I already have whatever I need.' Krune smiled, realizing that the second reservoir was almost full of fish. If it wasn't for the fact that he had cooled down the temperature of the place and had always added in ice with the healing effect, their numbers wouldn't have grown this much.

After all, with the healing effect, they would also remain healthy and at the prime of their life. Moreover, they were being fed with food that was rich with energy and nutrition, enough to overwhelm them if they weren't active.

So, this caused their population to snowball out of control. However, it was easy for Krune to limit their numbers. Using his Sonic Radar, he scanned through the fishes with the lowest density in the lot, scooping them out with a fishing net.

He captured around a hundred each day, grinding them into pulp before adding them to the first reservoir. This way, he reduced the population of the white fishes while the blue fishes continued to increase. Soon, there were only blue fishes in the place.

Krune brought some to the kitchen and made a meal for the three, using all the condiments of the place. There didn't exist any plants in the place or in the entire city for the matter. With that, Krune only had mineral condiments to work with.

Even then, the food turned out great. As he served them, Flita began to cry at the taste and the amount of energy she felt from eating each morsel. As for Wrister, he looked at Krune like he was some kind of god, for he never thought it was possible to obtain such energy-rich nutrition.

A hundred days after he started with everything, Krune managed to reach the peak of Tier 1. As he had the tremendous experience of growing stronger by leaps and bounds every time, Krune quickly adjusted to his newfound strength.

As his overall abilities and physique grew stronger as a whole, adjusting to it was really easy. With that, once he used his healing effect on Wrister, the old man cried with tears of joy as his wounds healed at a faster pace.

He was still severely injured, though, even after Krune almost emptied his reserves. But now, he was assured that it wouldn't be long before he made a complete recovery. Krune had already finished healing all of his internal injuries.

Now, only his limbs remained to be healed. By his estimates, it wouldn't take longer than three months before Wrister was completely healed. Once he reached the peak of Tier 1, Flita brought in a different variety of grapes, saying, "Unfortunately, we don't have any Tier 3 Demon Cores with us now. Fortunately, we have enough Tier 2 Demon Cores for you to reach the peak of Tier 2."

"That's fine." Krune nodded in response. "You've been a great help to me."

"Oh no, not at all." Flita waved her hands as she replied, "It is us who are grateful for your help. The Godly Points in our possession weren't even enough to reduce the severity of grandpa's injuries. You have helped us tremendously."
