"A mouse that can be seen in a previous family is more than two meters long, so wouldn't the size of a large fierce beast such as a lion and a tiger exceed more than ten meters!" Su Yehan thought with some fear, although he was a wolf, his body size was only the size of a palm after all, and he was too weak in this forest full of dangers.

"Fortunately, Lao Tzu has an infinite killing evolution system, as long as you keep killing and get enough energy points, you can evolve, gain powerful power, and have the power of self-preservation in this forest of endless crisis!" Su Yehan thought with some excitement.

Then he didn't hesitate, and his eyes scanned the surroundings, looking for a suitable target to hunt.

There was no suitable target except for tall bushes around, and while Su Yehan sighed, his heart moved, and his forelimbs began to gouge on the ground.

After a few breaths, an earthworm more than ten centimeters long appeared in front of him.

After a slight hesitation, Su Yehan endured his nausea and swallowed the earthworm into his mouth.

Su Yehan is only the size of a palm now, and he can only hunt earthworms, which have no attack power and are very weak.

The next moment, the system's prompt sounded in his head.

"Ding! Congratulations to the host for killing the earthworm and gaining two energy points!"

"The first evolution requires a hundred energy points, and I need fifty earthworms!" Su Yehan thought to himself, and his forelimbs were gouged into the ground again.

"Ding! Congratulations to the host for killing the earthworm and gaining two energy points!"

"Ding! Congratulations to the host for killing the earthworm and gaining three energy points!"

"Ding! Congratulations to the host for killing the earthworm and gaining a little energy!"

......

Every few tens of seconds, in Su Yehan's mind, the system's prompt sound would sound.

The amount of energy obtained by killing an earthworm is also not fixed, but is determined by the size of the earthworm.

The larger the body, the more energy you have in your body, and the more energy you get, and vice versa.

Of course, Su Yehan killed earthworms, and the energy value was the most, and it was only three points!

Half an hour later, Su Yehan couldn't remember how many earthworms he had killed.

"System, open the attribute panel!" Su Yehan commanded in his mind.

"Host: Su Yehan!"

"Species: Little Milk Wolf!"

"Grade: Harmless critters to humans and animals!"

"Skill: Extreme Speed!"

"Energy: 68/100!"

In half an hour, Su Yehan had already gained sixty-eight energy points just by killing weak earthworms, and he was only thirty-two energy points away from his first evolution.

"There are no earthworms under this bush anymore, go look elsewhere!" Su Yehan thought to himself, and cautiously walked out from under the bush.

After looking around and seeing that there was no danger, he became bold.

Soon, Su Yehan discovered a new target, a five or six centimeter mantis.

"Ding! Congratulations to the host for killing the praying mantis and gaining two energy points!"

After a few breaths, Su Yehan killed the mantis and gained two energy points.

Then, Su Yehan came to a bush again and plowed the ground with his forelimbs, but, unfortunately, this time, he did not find a single earthworm.

"Huh?" Just when Su Yehan was a little depressed, he suddenly heard a rustling sound, and then, a sense of crisis surfaced in his heart.

Don't think too much, Su Yehan surged forward with the strength of his limbs, and at the moment when his figure rushed out, a terrifying snake head, spitting out a letter, his sharp teeth glowing with cold light, bit into the air.

The prey that reached the mouth actually ran away, and the giant snake was unwilling to give up, and its body more than three meters long swung and chased after Su Yehan who escaped.

Su Yehan's soul was in full swing, and his speed was exerted to the extreme, constantly shuttling under the bushes, while the big snake that attacked him was closely chasing behind.

The speed of the big snake is very fast, compared to Su Yehan, it is still inferior, although Su Yehan is relatively small, but he has the extreme speed of the almost anti-heaven skills.

Under the ten-fold speed bonus of the extreme speed, Su Yehan left the big snake behind him little by little.

Seven or eight minutes later, Su Yehan was relieved when he heard that there was no movement behind him.

"Damn, you have to evolve, otherwise, it's too dangerous, and you may die at any time!" Su Yehan scolded in his heart.

No way, in this unknown primeval forest, he is a little milk wolf with a big palm, and he really has no wolf rights!

"Big snake, big mouse, you wait for Lao Tzu, and when Lao Tzu evolves, he will definitely kill you!" Su Yehan was ruthless in his heart, for these two guys who dared to sneak attack him, it was absolutely impossible to let go easily.

However, Su Yehan can only think about it now, if he wants to take revenge, he must evolve.

The first priority is to hunt creatures and get enough energy.

Without hesitation, Su Yehan began to carefully look for a suitable target.

"Ding! Congratulations to the host for killing the praying mantis and gaining five energy points!"

"Ding! Congratulations to the host for killing the grasshopper and gaining four energy points!"

"Ding! Congratulations to the host for killing the centipede and gaining five energy points!"

Maybe it is because there will be a blessing in the future if you don't die, and in the next time, Su Yehan was very lucky, and he found suitable hunting targets one after another, and he did not encounter any danger.

After opening the attribute panel and taking a look, Su Yehan found that at this time, his energy value had reached ninety-nine points, which was only a little short of what was needed for the first evolution!

"Haha, that's good, as long as you get a little energy value, you can evolve, big snake, big mouse, you wait for Lao Tzu!" Su Yehan laughed wildly in his heart while looking for the next target.

"Haha, it's you!" Soon, Su Yehan found a caterpillar on an unknown dwarf plant.

Without hesitation, Su Yehan came to the caterpillar, slapped his little paws, and the caterpillar died directly.

The next moment, the prompt sound of the system sounded in Su Yehan's mind.

"Ding! Congratulations to the host for killing the caterpillar and gaining a little energy!"

"Ding! The system detects that the host has obtained enough energy value to meet the evolution conditions, will it start to evolve?"

Two system prompts sounded in Su Yehan's mind, and when he heard this, he was extremely excited, and said, "Start evolving immediately!"

"Ding! This evolution takes thirty minutes, and if you are interrupted in the middle, it will take twenty-four hours before you can evolve again, do you want to confirm it?"

The prompt sound of the system sounded again, and when Su Yehan heard this, he did not reply to confirm, but cautiously looked around and began to look for a place that would not be disturbed.

If he is really interrupted in the process of evolution, and it will take a day to evolve again, then Su Yehan will have no place to cry.

With his current palm-sized size, it would be difficult for him to survive a day in this forest.
