(Come and collect a few!)

A grass carp is constantly tossing and jumping by the clear stream!

"No……"

When Jia Yan pulled out his mouthpart from the head of this grass carp.

The grass carp was silent, and its huge body was lying in the cold sand and stone ground, losing its breath!

Jia Yan was silent for a moment, then shook his head.

After his investigation, he did not find any mysterious juice in the brain of this grass carp!

Then his guess is correct.

Whether it is the medicine liquid from the Northeast Wild Tiger Factory, the black liquid, or the underground world, the only things they can promote mutated growth are insects, and it may even be some specific species among insects!

Jia Yan is not sure about some of the secrets in this, but at least he found this most basic rule!

"I have never even seen purely flying insect mutations succeed. Of course, the giant in this underground world cannot be counted because they are the indigenous people here and do not belong to mutated creatures at all."

"Then my mutation will be unique. If my previous guess is correct, the Dipteran insects are not unable to mutate, but because their physique is too weak and cannot accept the destruction of the mutant power, they become a mortal ending."

"It is precisely because my body was too weak before that my progress and plasticity are the greatest! The body that mutated step by step, the weak body that was previously covered by the mutation process, so I will have the potential to grow than other centipedes with strong bodies!"

It is precisely because of weakness that it is more likely!

Jia Yan looked around and saw that the ground by the stream was the place where the fiery red centipede died a few days ago. But now there is no corpse of the fiery red centipede here, and I don’t know which carnivore was dragged away by it!

Throwing the big fish in place, Jia Yan flapped his wings and flew up from the ground...

Continuous analysis during flight.

Some things are more thoughtful, the clearer they will be.

Jia Yan flew over a bush!

This shrub should actually be called grass, but because these plants are too lush, they become like large shrubs and cover a very wide area.

It was in this bush that there was a pair of huge bulging eyes staring at Jia Yan's flying figure.

When Jia Yan flew over the eyes!

The pair of raised eyes rolled suddenly!

The next moment, the owner of this eyeball suddenly spit out the soft and slender tongue!

The tongue was like a flexible little snake, making a sound of breaking through the air, and electricity shot towards the flying creatures in the air!

Jia Yan was in the air, thinking about things, but he had a human soul, but he could not stop thinking for a moment, so sometimes his vigilance would become less.

The moment the long tongue shot out, he also saw the object attacking through his compound eyes!

He also wanted to hide, but his tongue was too fast!

Before he could dodge, his long tongue stuck to his abdomen, and then a huge force pulled him down!

At this time, the predator's figure was exposed to Jia Yan's eyes. This was a giant toad with disgusting objects all over his body and goose bumps all over his skin!

This toad is over thirty centimeters in size and is a lump on the ground. It is really huge.

"Hmph, it's just a huge toad!"

Jia Yan's eyes flashed strangely, and then he slapped his wings hard!

Buzzing!

The whole body flew upwards and easily broke free from his long tongue that was stuck to him.

Jia Yan, who has mutated so many times, has long been stronger than his body shape. He can't even guess how much strength he has now!

The mosquito's body turned around in the air, aimed at the toad below, and attacked him in front of his head!

"No! This toad looks poisonous."

In the air, Jia Yan looked at the toad with a bump on his body and sighed unwillingly, but he still flapped his wings and flew away from this bush!

Even if the toad is not poisonous and is such a disgusting creature, he doesn't want to assassinate it.

He doesn't eat meat, so killing is not good, right?

"It seems that we will try it in the future. Whether your body has resistance to toxicity, but mutation is not omnipotent. Even if the body has resistance, it is impossible for all poisons to be invincible."

The sound of mosquitoes flying was very far away in the underground space.

In fact, this space is only about five kilometers long and wide. If Jia Yan flies with all his strength, it will not take long to fly from one side to the other.

But he did not do this, but kept patrolling at high altitude.

"There seems to be objects from the human world on the ground over there!" Not long after, Jia Yan saw some shining things on the ground.

He flew over.

After observing the left and right, confirming that there was no danger, Jia Yan controlled his body and landed.

This is a mirror with a phosphorescent surface. Even after many years, it can still reflect Jia Yan's mutated hideous mouthpiece very clearly.

"It seems that those humans who died in the cave have also come here." Jia Yan looked around and found no more human objects, so he flew directly into the sky.

There are too many reasons why humans may die in this underground world.

Those humans look like they are wearing military uniforms and equipped with guns and ammunition. However, there are many terrifying huge creatures in this underground world. Jia Yan can come and go freely now because he has the advantage of flying.

If humans advance on the ground, they will be very likely to be killed when they encounter huge creatures.

Of course, for humans with thermal weapons, ordinary giant creatures may not be enough to stop them.

But the other most powerful killer will definitely make them, who have hot weapons, helpless and can only wait for death!

That is the toxins in the air!

That's right, Jia Yan thought about it. Although he guessed that the air in the underground world is a key factor in the enormousization of animals, it is not necessarily such a good thing for humans.

This chapter is not finished yet, please click on the next page to continue reading the exciting content behind! Even for many creatures, this is not an easy place to survive.

So Jia Yan could roughly calculate the scene decades ago.

Finally, some huge human teams of humans who had finally killed them, but they became poisoned and died due to toxins in the air. In the end, when they escaped to the cave, a large part of them died on the road!

"Then some Japanese institutions have discovered that the air in this underground world has special substances!"

"Immediately afterwards, the factory appeared above the crack connected to the cave. Next, war broke out in factories and other places!"

"It was forgotten and abandoned for decades until it was reopened by the Northeast Wild Tiger using some means. This... should be the whole process of the incident."

Jia Yan felt that his guess was almost the same.

Buzzing.

He is still flying in the air.

Sometimes there are even some huge creatures below, attacking him who have a flight height of up to ten meters!

A bug that looked like a kowtower worm, but its body was hundreds of times larger than that of an ordinary kowtower worm. This guy thought Jia Yan had invaded his territory. When Jia Yan flew over its territory, his head hit the ground and his body instantly ejected, hitting Jia Yan flying in the air!

Jia Yan naturally avoided easily, and the kowtow worm didn't even touch a hair of his hair.

The number of organisms here is very large, but for some reason, the food source is also extremely abundant.

At least such a large number of organisms can be maintained to reproduce and survive here.

They are full of aggressiveness. Not to mention carnivorous animals, even vegetarian creatures like kowtowworms are extremely violent!

"I don't know if it is affected by the special air and environment here, so I should pay attention to it..."

Jia Yan felt that it was necessary to control his impulse torture, otherwise what would be different from these wildlife?!

Just as Jia Yan continued to explore this world.

"What is that? Is it another human object?"

A thing lying on the ground, almost half of which was buried in the soil, was keenly observed by Jia Yan's compound eyes!

Jia Yan looked around.

On the ground, there was a giant snake with a body of more than three meters hovering on the ground to rest.

This giant snake is obviously a cobra species, but its body shape is directly green and very similar to the colors of those plants.

Jia Yan looked at it hesitantly and then buried the human item less than five meters behind the giant snake.

He was considering whether to go down and explore the item!

If it is a mirror or a bad helmet, there is no need to take risks. Because no matter how you look at the giant snake, it is not easy to mess with...

"It seems that it's not a mirror or a helmet or something. This is... a notepad?!"

Jia Yanfu's eyes were faint!

For notepad, there is really a need to take the risk to grab it!

Because this kind of notepad is usually used to record some important events. Especially if humans are soldiers, they may be more official records.

If some secrets are recorded above, or other important things discovered by these humans here, it will be of great help to Jia Yan.

Although... Jia Yan doesn't understand Japanese or anything else.

However, the Japanese writings are too influenced by Chinese writings, and a large part of them are in Chinese. Even if you guess and misunderstand, you will have a great chance to guess what it means!

Thinking of this, Jia Yan made a decision!

His flying sound had long aroused the warning of the green cobra below.

At this time, the big snake's muscles were spreading out at seven inches, like a pair of small wings. The snake's mouth made a "hiss" sound, constantly spitting out snake letters!

This is a threat to Jia Yan!

"No matter what, I'm going to get this notepad!"

Jia Yan flew towards the big snake!
