Entering the cave, Yang Heng found that except for the entrance of the cave, it was very spacious.

The walls of the passage are full of claw marks, which must have been dug up by these mutated animals.

I haven't felt it on the outside, but every rush of energy inside will bring an indescribable smell.

Rotten, foul-smelling, and mixed with the smell of various animals.

It was dark in the cave, and Yang Heng could only rely on his strengthened vision to slowly grope his way forward.

Not long after walking, there was a light slowly coming from the front, and Yang Heng hurriedly stepped up.

Walking closer, Yang Heng got used to it and looked around.

In front of me was a huge cavern, about the size of a dozen football fields.

In the middle is a blood-red cocoon, connected by a thick tentacle underneath, and the other end of the tentacle goes deep into the ground.

Four small tentacles protrude from the cocoon, connecting the four small cocoons around it.

There was a group of mutant animals lying around.

The palpitating energy is transmitted from the tentacles in the ground into the cocoon, and the cocoon retains most of its energy.

The remaining small part is then transported from the cocoon to the other four, and the four cocoons absorb the overflowing energy and then disperse from the cocoon shell.

The crouching animals on the ground breathe with the energy emitted by the shock and slowly evolve.

Yang Heng watched all this in shock.

None of the mutant animals on the ground seemed to be dormant below F-class, there were many E-class, and there were even four D-class closest to the giant cocoon.

And judging from the energy fluctuations on their bodies, they are only higher than themselves.

The energy Yang Heng in those four small cocoons is estimated to be C-level.

As for the giant cocoon, Yang Heng couldn't feel its upper limit at all, as if there was a prehistoric giant beast standing in front of him, and he was just an ant.

Looking at all this, Yang Heng felt strongly uneasy in his heart.

Could it be that the race of octopus monsters from before was responsible for all this?

Who is the person or monster behind it?

These mutant animals were obviously summoned here for intensive evolution, where did that tentacle come from? Why is there such a strong energy flowing through?

This is just a district of Pengcheng!

With so many countries and so many cities around the world, how many of these things have to happen!

Yang Heng has a strong urge to destroy all this, and then chase this tentacle to see who is behind it!

Clenched his fists and took several deep breaths in a row before Yang Heng suppressed this thought.

"Now my strength is not enough, rushing forward is looking for death, tell Fang Ling the situation first, and then make a decision." Yang Heng thought secretly.

But not doing stupid things doesn't mean that Yang Heng doesn't do anything.

Yang Heng picked up a stone and threw it at the nearest beast.

If these evolving beasts are awakened, then flee as soon as possible, and then send the news out as soon as possible.

If they are all dormant, as they were when they evolved, then they must be able to kill as many as they can to avoid all of them evolving to a high level, and then the harm will be too great.

Syllable!

The stone hit the forehead of the nearest cat, which did not react at all.

Yang Heng felt a little calmer, and picked up a few more stones to continue the experiment.

After testing, Yang Heng found that the lower the level of the mutant beast at the back, the more unresponsive it was.

One of the stones, Yang Heng, threw it hard to the innermost, just as it was impacted by the energy, and it was crooked a little, almost hitting a D-class mutant beast.

As a result, the mutant beast only moved its eyelids and did not open them, so frightened that Yang Heng almost turned around and fled.

Yang Heng, who was relieved, pulled out his knife and slowly approached the outermost mutant beast.

These mutant beasts have all reached the F level, so it means that they all have evolution crystals in their bodies.

Now is the time to consume the enemy and strengthen yourself.

Yang Heng tiptoed close to the mutant beast, and the katana in his hand sliced off the skull.

Poof!

The F-class mutant beast itself couldn't block Yang Heng's attack, let alone this defenseless state.

Yang Heng slashed one by one, quickly killing mutant beasts and capturing the evolution crystal.

"Except for the first few who are about to evolve to the D-level, the rest," Yang Heng's eyes flickered with a cold light,

"All have to die!"

It didn't take long for Yang Heng to get dozens of evolution crystals, and his shirt had already been taken off and made into a simple package by Yang Heng.

······

"The seventy-ninth." Yang Heng picked up an evolution crystal, wiped it on his pants and threw it into the bag behind his back.

Counting the number of evolution crystals while killing, Yang Heng had a feeling of unreality.

From the beginning of the disaster to the present,

The cautiousness at the beginning, the trembling and now the ability to protect oneself is enough.

When was it so easy to get an Evolution Crystal?

It's almost like picking up beans.

One Knife,

Split the shell,

Bend down and pick up a bean.

Look, an evolution crystal in hand.

Yang Heng took a breath and looked at the black pressure of a mutant beast in front of him, his eyes were full of excitement.

You spent so much energy to create so many F-level and above mutant beasts.

I took it for you!

Don't thank me~

After sighing, Yang Heng continued to carry out the great cause of "picking up beans".

······

"That's full?" Yang Heng looked at the clothes behind him, which were already full of evolution crystals, almost more than two hundred.

Looking at the remaining mutant beasts, there were many, many more.

"It seems that we have to go out first, use up the evolution crystal, and then change to a larger bag to hold it." Yang Heng thought.

With the bag on his back, Yang Heng turned around and ran towards the exit.

······

"It should be almost to the D-rank high level," Yang Heng was excited after using the evolution crystal in his clothes and feeling his body further strengthened.

"We have to hurry up and find a big bag to continue," Yang Heng, who couldn't wait, hurried to find the package.

After finding a few bags, Yang Heng hurried back the same way.

"It's fine." Seeing that the cave was still the same as before he left, Yang Heng breathed a sigh of relief and began to continue harvesting.

······

Gathering place Ling stood under the transport plane and kept dialing Yang Heng's phone, his face full of anxiety.

"Lieutenant Colonel Fang, it's getting dark soon, we can't wait any longer, we must leave immediately." A middle-aged soldier walked over and said to Fang Ling.

"Wait another ten minutes." Fang Ling replied, the phone in his hand kept stopping.

"Fang Ling, you go back first, I will continue to contact him here, if I get in touch, I will inform you as soon as possible." A young man next to him patted Fang Ling on the shoulder and said.

"Okay, if you have news of him, you must notify me as soon as possible, please Hou Yong." Listening to the voice on the phone that could not be connected, Fang Ling said to the other party.

"Don't worry."

Seeing that Hou Yong agreed, Fang Ling could only reluctantly walk towards the transport plane.

In the transport plane, Qian Xiaoyi was tied up like a zongzi, and when he saw Fang Ling coming, he made a whining sound in his mouth.

"Don't worry, Yang Heng is already D-level, and he must be fine." Fang Ling comforted.

Yang Heng never returned, and Qian Xiaoyi didn't leave, so Fang Ling could only forcibly take him away according to Yang Heng's explanation.

Who knew that something was wrong, Qian Xiaoyi was actually an awakened person, and his ability was wonderful, and all the power used on him would be rebounded.

I didn't dare to use the tricks that were more powerful, and it took a lot of effort for a group of people to catch him.

"None of them are worry-free." Looking at Qian Xiaoyi, Fang Ling thought of Yang Heng again, and said hatefully.
