The river runs through the mountains and forests, up to fifty or sixty meters wide, and the river is constantly collapsing, and on both sides of the river, there are all kinds of wild beasts.

And among them, Su Yehan found a familiar figure.

The big rat that attacked him at the beginning!

"Damn it, Lao Tzu has been looking for you for so long, you actually came here, as long as I kill you, Lao Tzu can evolve again!" Su Yehan sneered in his heart, his eyes glowing coldly.

Then he didn't hide his body, his limbs were exerted, and his speed exploded to the extreme, heading towards the big rat who was drinking water.

With the appearance of Su Yehan, the beasts that were drinking water let out frightened cries and fled in all directions.

The big rat naturally discovered Su Yehan at the first time and felt a strong crisis.

Without the slightest hesitation, it ran and squeaked.

Although there was no shortage of beasts by the river that were larger than the big rats, Su Yehan turned a blind eye.

Since the big rat dared to sneak attack him before, then Su Yehan would not let the other party go.

Su Yehan has an extreme speed of ten times the speed bonus, and his body size has reached three meters, far exceeding that of the big mouse.

Although the two sides were dozens of meters away at the beginning, it was only a few breaths, and Su Yehan had already reached behind the big mouse.

"Roar!"

Su Yehan let out a wolf howl, his limbs were exerted, and his three-meter-sized body was like an arrow from the string, heading towards the big mouse.

The huge mouth opened, the sharp wolf teeth glowed with coldness, and the next moment, the knot bit firmly on the neck of the big mouse.

With a bang, the big rat fell to the ground, struggling like crazy, trying to get rid of Su Yehan.

But this is destined to be in vain, no matter how much the big rat struggles, he can't break free from Su Yehan's huge mouth.

After dozens of seconds, the big rat stopped struggling and died of exhaustion.

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

"Ding! Congratulations to the host for killing the big rat and gaining 100 energy points!"

"Ding! The system detects the host to obtain enough energy value to meet the conditions for evolution, does it evolve?"

Two system prompts sounded in a row, and Su Yehan was extremely excited.

However, at this moment, a strong sense of crisis suddenly appeared in my heart, and then a heaven-shaking tiger roar came.

"Roar!"

The roar of the tiger shook the sky and the earth, startling countless birds in the forest to rise into the sky.

And Su Yehan, the moment he heard the tiger's roar, he secretly said that it was not good, and he couldn't think about it, the strength of his limbs exploded, and his body rushed out more than ten meters away.

"Sting!"

The next moment, Su Yehan had a sharp pain in his hind limbs, and he didn't have time to look back, his speed exploded to the extreme, and he rushed towards the front.

Behind him, a yellow and black tiger roared and chased closely.

"Damn, Lao Tzu reacted fast enough, but on the hind limbs, he was still injured!"

Su Yehan was furious in his heart, he had just killed the big rat, avenged the sneak attack, and obtained the energy value needed to evolve again.

But before he had time to be happy, he faced another death crisis.

This is also to blame for his carelessness, Su Yehan thinks that he has extreme speed and extreme strength, these two powerful skills, he should be fearless in this forest.

But the truth is far from what he thinks.

As he hurried forward, he looked back behind him.

Seeing this, Su Yehan was shocked beyond measure!

"This ...... How could there be a tiger of such a huge size!"

Su Yehan was a little incredulous.

Whether it's a three-meter-long snake or a half-meter-sized mouse, they exist on Earth.

However, the tiger, which is more than eight meters in size, is unbelievable.

As far as Su Yehan knows, on the earth, the largest tiger, the Siberian tiger, is only about three meters in size, even if the tail is added, it will not exceed five meters.

"Roar~!"

Behind Su Yehan, the tiger erupted into a roar, which made Su Yehan wake up in shock, and he didn't dare to think nonsense.

Su Yehan's body size is three meters, while the tiger's body size is about eight meters.

Even if Su Yehan has an extreme speed of ten times the speed bonus, in terms of speed, he is only comparable to the tiger.

"What kind of world is this, I have to be more careful, perhaps, this tiger is not the largest beast here!" Su Yehan thought so, not daring to slow down in the slightest.

Su Yehan is self-aware, even if he has extreme speed and extreme strength, he will definitely not be the opponent of the tiger behind him.

"Roar~!" At this time, the tiger behind him roared again, it didn't expect that the speed of this guy in front of him was so fast.

"Let you be arrogant, when Lao Tzu evolves again, it will be your death!" Su Yehan was angry in his heart.

"Wow!"

At this moment, in front of Su Yehan, the river suddenly exploded, and then, a terrifying giant beast appeared, its huge mouth opened, and it bit towards Su Yehan.

Su Yehan was shocked, and hurriedly changed direction, avoiding the bloody mouth of the terrifying giant beast.

Su Yehan dodged, but the tiger behind him was not so lucky, how could it collide with the giant beast that suddenly appeared in the river.

"Roar!" the tiger erupted into a roar of earth-shattering rage, and a pair of tiger eyes stared at the beast that suddenly appeared.

This sudden appearance of the giant beast made the tiger not chase Su Yehan, and it can be regarded as helping Su Yehan.

Su Yehan felt the movement behind him, stopped, and looked back.

I saw a terrifying crocodile with a body length of more than ten meters and a height of nearly one meter confronting the tiger.

The crocodile was pitch black, and it seemed to have a layer of scale armor on its body.

The savage aura exuded by the terrifying crocodile is even more than that of the tiger.

"Roar~!"

"Roar~!"

The tiger and the terrifying crocodile burst out at the same time, and the next moment, they fought fiercely.

The tiger is known as the king of beasts, and this is on land, although it is not as big as a terrifying crocodile, it is not afraid of the other party.

"Let's fight, it's best to lose both!" Su Yehan sneered in his heart and turned to leave.

No matter who lives or dies between the tiger and the terrifying crocodile, Su Yehan doesn't care.

The top priority is to evolve again, and to improve one's combat power again, so that they can survive in this forest.

Su Yehan entered the mountain forest, found a huge cave, entered it, and instructed the system: "System, start evolving immediately!"

"Ding! The system test meets the conditions for evolution, this evolution takes an hour, if it is interrupted in the middle, it will take three days before it can evolve again, does the host confirm the evolution?"

"Confirm!" Su Yehan said impatiently.

"Ding! Evolve!"

As the prompt sound of the system fell, Su Yehan's mountain-like wolf body was once again surrounded by a warm and comfortable feeling, as if it was soaking in warm water.

With the beginning of evolution, Su Yehan's body size began to grow again at a rate visible to the naked eye.
