A large amount of Netherworld Poison poured into the Mammoth Colossus's body like a madness, and then, Su Yehan quickly retreated without waiting for it to fight back.

"Ang!" the mammoth roared, its huge eyes staring at Su Yehan.

The next moment, he came towards Su Yehan.

The Mammoth Colossus was so large that it ran so much that even the earth shook.

"If you fall victim to the poison of the Netherworld, you just wait to die!" Su Yehan sneered in his heart, easily dodging the attack of the Mammoth Colossus.

In the following time, Su Yehan did not fight with it, relying on his absolute speed, dodging the attacks of the mammoth colossus again and again, and spit out Netherworld Poison Flame and Huangquan corpse qi from time to time.

Although the Mammoth Colossus has rough skin and thick flesh, the damage of these two skills to it is limited, but it can't stand up to many times, and after accumulating again and again, the body surface of the Mammoth Colossus has been blurred with flesh and blood.

And as time passed, the Nether Poison in the Mammoth Colossus's body has gradually attacked.

Su Yehan was relieved when he saw this, let out a wolf howl, and pounced towards the other party.

The mammoth colossus was already seriously injured at this time, and in the face of Su Yehan's culling, he couldn't dodge at all, and he could only roar again and again.

After only a minute or two, it collapsed to the ground and died.

"Ding! Congratulations to the host for killing the Mammoth Colossus and gaining 1.9 million energy points!"

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

"There are only five or six hundred thousand energy points left before evolution!" Su Yehan thought as he looked into the depths of the island.

"After evolving again, you can move forward again, I don't know what secrets are hidden on this Skull Island!"

Without thinking too much, Su Yehan's powerful perception ability spread out and began to look for the next hunting target.

"Forty thousand meters ahead, there is a titan monitor lizard with a body size of 100 meters, it's you, as long as you are killed, Lao Tzu can evolve again!"

After a dozen minutes!

"Ding! Congratulations to the host for killing the Titan monitor lizard and gaining 1.3 million energy points!"

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

The prompts of the two systems sounded in Su Yehan's mind.

Su Yehan was extremely excited, however, his current body size had reached one hundred and fifty meters, and it was not easy to find a hidden place that would not be disturbed to evolve.

In desperation, Su Yehan could only return to the cave of the eight-eyed poisonous spider.

"System, start evolving!"

"Ding! The system detects that it meets the conditions for evolution, this evolution takes five days, and if it is interrupted in the middle, it will take fifteen days before it can evolve again, may I ask the host, do you confirm the evolution?"

"Confirm!"

"Ding! Evolve!"

As the system's prompt sounded again, Su Yehan began his sixth evolution!

The first to begin to change was still his wolf body.

One hundred and sixty meters!

Two hundred meters!

Two hundred and thirty meters!

Three hundred meters!

When three days passed, Su Yehan's body size reached an unexpectedly 300 meters, which was terrifying.

At this time, his size was not growing, but then, it was not as before, the strange energy gathered between his eyebrows, opening up the eyes of the sky.

Instead, he clearly felt a wave of energy gathering in his limbs, strengthening his body.

Su Yehan has evolved five times, and his wolf body is not weak, although he has not been actively strengthened a few times before, but he has also been indirectly strengthened, of course, the effect is far less than the current active strengthening.

Su Yehan could clearly sense that his wolf body was getting stronger.

This feeling is like his body was a pile of sand before, very loose, and now although it is still sand, it has become more solid with the addition of water.

After five or six hours passed, Su Yehan felt the energy in the hundreds of limbs dissipate, and the strengthening of his body ended.

After the body reinforcement ended, the next thing that changed was his perception.

Now he can perceive a radius of 50,000 meters, and now, this range is growing rapidly.

60,000 meters!

70,000 meters!

90,000 meters!

It didn't stop until it finally grew to 100,000 meters.

100,000 meters, that is, 200 miles, 100 kilometers!

This may seem like a lot, but on Skull Island, which is comparable to a continent, it's nothing.

After the perception range stopped growing, a strange energy began to gather between Su Yehan's eyebrows, continuing to open up the Heavenly Eye.

This also made Su Yehan breathe a sigh of relief, the legendary Tianyan, he was looking forward to it.

There was an itchy feeling between the eyebrows, and Su Yehan could clearly feel the changes between the eyebrows.

"It seems that this time the Heavenly Eye still can't be opened successfully!" Su Yehan thought to himself, and this is indeed the case.

When the strange energy between the eyebrows dissipated, the Heavenly Eye was not successfully opened, but Su Yehan was not lost, at most he would evolve again, and the Heavenly Eye could be opened up.

Five days passed, and the prompt sound of the system sounded in Su Yehan's mind.

"Ding! Congratulations to the host for evolving to level six, obtaining new skills, soaring through the clouds, please check the latest attributes!"

"Host: Su Yehan!"

"Species: Wolves!"

"Level: Level 6!"

"Skills: Extreme Speed, Extreme Strength, Nether Poison, Nether Wolf Flame, Extreme Spiritual Sense, Huangquan Corpse Qi, Nether Poison Flame, Soaring Clouds and Mist!"

"Energy: 10 million points/100 million points!"

As always, after this evolution, if you want to evolve again, the energy required has increased tenfold again, reaching 100 million energy points!

But at this time, Su Yehan couldn't care about these anymore, because the skills obtained from this evolution were soaring clouds and mist!

Even if he didn't look at the details of the skill, just by looking at the name, Su Yehan could know that with this skill, he had the ability to fly.

The eyes fell on the new skill, and the next moment, the details of the skill emerged.

With this skill, the host can fly in the air, consuming five energy points per second!

"Haha, cool, I've evolved six times, and I can finally fly!" Su Yehan roared in his heart after reading the details of Tengyun Driving.

Being able to fly in the sky not only improved Su Yehan's hunting ability, but also greatly improved his life-saving ability, and most importantly, he could find a flying pterosaur for revenge.

"Flying Pterodactyl, wait for Lao Tzu, I can't spare you!"

"Soar through the clouds!"

The evolution has ended, and Su Yehan did not stay, and used a new skill to ride the clouds for the first time.

The moment the skill was used, Su Yehan's three-hundred-meter wolf body slowly floated.

The next moment, Su Yehan's heart moved, and he walked towards the entrance of the cave.

Since Su Yehan had evolved again, the entrance of the cave was no longer enough to let him out, but this was naturally not a problem, and with a few waves of the wolf's claws, the entrance of the cave expanded to a size of four hundred meters.
