Then the snake reached into the water and started to hunt rapidly. To fill his energy to full and heal faster. The lake's animal population began to lessen rapidly as the days passed. The snake's most superficial injuries healed and the energy also filled to the brim in the body.

This time John didn't hesitate, as he began to activate the endless growth talent without stopping even if he got his lifespan depleted. The cells began to get active and the new cells were born at a rapid pace his tail regenerated and his body began to strengthen and grow longer. Large amounts of dead cells, scales, and other waste things began to fall.

A few moments later, the process ended with a newly grown black snake that was a meter longer than before and stronger than before. John looked intoxicated at the process of strengthening. His eyes showed confidence that he lost from fight with the golden eagle.

John murmured to himself while looking at the sky(What if I lost to you. I will kill you soon! without much effort.)

Then he immersed himself in the water and faded away. To hunt and store more energy to grow again at the cost of lifespan depletion. He doesn't want to be in the same situation as he had been in previously with the golden eagle.

Even though he's seen eagles that are larger than the golden eagle previously. They didn't think about hunting him or capable of inflicting any injuries on him. So they all ended up in his stomach. But this golden eagle is different it has something that other normal eagles don't have.

It had sharper claws and beaks than the normal bigger eagles. It is much faster than normal eagles and its reaction speed is also much faster. So, John is puzzled as to why this golden eagle is much stronger than him and other animals.

There may be a reason for that, but he doesn't know that and can't seem to find it. So abandoning those thoughts, he began to hunt and fill up the energy bar. Because If he keeps strengthening himself, there will be a level where he can hunt them down with ease. With his increased growth. The reaction speed, eyesight, and hearing are also returning to a normal human level.

Days turned into months, and the animal population in the lake began to decrease at a rapid pace. As the size of the snake began to increase at a rapid pace.

The animal population in the surrounding forest also decreased in a few months. This crazy hunting continued for months before stopping suddenly. The surrounding forest becomes devoid of any animals. The lake also turned purple.

Everything in the lake and the surroundings died. The lake became a large swamp where various poisonous insects and animals thrive. The surroundings were also covered in thick fog making it hard for any birds to come near them. As anything that touches the fog dies in moments.

Making the lake and the surroundings a paradise for small insects and animals with poison resistance to survive and grow rapidly. This is all possible because John controlled the amount of poison he released to the lowest level to see if some species could survive. To his astonishment, all the species without poison resistance died. Only poisonous species from plants, insects, and fishes to mammals survived.

In the purple lake, two large crimson eyes appeared before the purple tree that grew from the lake base. John looked at the purple tree with amazement and thought(So, there's still a fourth type of successful experiment. Which can successfully adapt to the evolutionary substance and can also grow into a unique species that grew rapidly and very differently from its parent's genes.)

The tree is one of the experiments that he experimented with in his free time to consume evolutionary substances. Due to the abnormal use of the evolutionary substance, the red drop is consumed rapidly and his all senses grow to an unimaginable level.

The mutated tree can now absorb its poison and release its poison always making the swamp remain poisonous and form its ecosystem. There are various insects, fishes, mammals, and even birds that depend on it to survive.

These mutated trees also began to grow all over the lake and covered most of the underground of the lake with its presence. The last bit of red drop is consumed by the mutated tree. John looked at the mutated poisonous tree and thought(There is no presence of an evolutionary substance in this tree. It probably evolved like this by consuming the evolutionary substance and induced mutation in its gene to adapt to this environment.)

The snake's eyes sharpened as it thought(The thing is, will only plants and trees adapt to the evolutionary substance, or can animals also possibly adapt and evolve with evolutionary substance? If so then the golden eagle that attacked me is also possibly an evolved species using evolutionary substance.)

Then the snake's eyes dimmed a bit as it thought(I can't use this method, as it is almost one in a thousand chances to adapt to an evolutionary substance and one in a million to successfully evolve into species with its traits without DNA breaking down.)

John's eyes sparkled as he thought at last (But I can choose their species as a species that I will be born next to possess all their abilities with little so effort.)

Then he looked at his hundred-meter grown body which stopped growing anymore to have time to choose the next species and gain knowledge about this world and its species. John looked at the remaining lifespan after depleting most of them in the growth process.

[ Bloodline Creature(1/4).

Age: 72/100 years.

Race: Snake(adult).

Talent: Endless growth(80%) ]

After depleting so much lifespan John had a sense of urgency to find the next suitable life form. As there's not much to do in a large snake body and he can't even research with this large body. John can't possibly mate with other snakes even if he wants with his large body. So it's better to find the next species that possibly has a civilization and can travel long distances to gather information.

Then John glanced at the sky with an intoxicated expression, as his eyes could finally see color and could find objects from a long distance with his ultra-wide clear eyes. He can now also hear from a large distance according to the proportion of his body. His sense of smell also evolved as he grasped numerous smells and pinpointed them accurately from a very long distance. Finally, the heat sense organ shaped like the horn on both sides of his head can pick up heat accurately from miles away.

With his ten-meter wide and hundred-meter-long snake body covered with metallic scales that can crush rocks with little force, when moving inside the forest. He can easily create a way for himself with little effort that will forever create a new water pathway for other animals.

Along with his high sense organs, no animal stands in his way. He also found a golden eagle that almost killed him in the sky. But that golden eagle flies away when he concentrates a little bit of his attention on it and doesn't dare to think of him as a hunting target. He also found a pair of golden eagles that were bigger than it.
