(Let's collect a few of them!) ）

By the clear stream, a grass carp keeps tossing and jumping on the shore!

"No ......"

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

This grass carp was already silent, and its huge body was lying in the cold sandy 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's the liquid medicine from the Siberian Tiger Factory, or the black liquid, or this underground world, the only thing they can promote mutation and growth is insect creatures, and maybe even some specific species of insects!

Jia Yan still doesn't know what secrets are in this, but at least this most basic law has been found by him!

"I've never even seen a pure flying insect mutate successfully, and of course, the giant moths of this underground world can't be counted, because they are the natives of this place, and they are not mutated creatures at all."

"Then my mutation will be unique. If my previous guess was correct, it's not that Diptera insects can't mutate, but because their physique is too weak to accept the destruction of mutated power, they become mortal. ”

"And it is precisely because my previous body was so weak that my progress and plasticity are the greatest! The body that mutated step by step, the previous weak body has long been covered by the mutation process, so I will have the potential to grow more than other strong centipedes and the like! ”

Because it is weak, it is more likely!

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

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

In flight, constantly analyzing.

There are some things, the more you think about them, the clearer they become.

Jia Yan flew over a bush!

This shrub should actually be called a grass, but because it is so lush, it becomes like a large shrub, covering 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 pair of eyeballs!

Those bulging eyes turned suddenly!

The next moment, the owner of this eyeball spit out the soft and slender long tongue in his mouth!

The tongue is like a nimble little snake, making a breaking sound in the air, and the lightning shoots at the flying creatures in mid-air!

Jia Yan was in the air, originally thinking about things, with a human soul, he couldn't stop thinking for a moment, so sometimes, his vigilance would become lower.

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

He wanted to hide, too, but the long tongue was too fast!

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

At this time, the figure of the predator had been exposed to Jia Yan's eyes, this was a giant toad with disgusting bumps all over its body, and its epidermis was full of pimples!

This toad is more than 30 centimeters in size, and it is a lump on the ground, which is really huge.

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

Jia Yan's compound eyes flickered, and then he slapped his wings hard!

Buzz!

The whole body flew upwards, and it was easy to break free of the long tongue that was clinging to him.

Jia Yan, who has mutated so many times, has long exceeded his own body size in strength, and he can't guess how much strength he has now!

The mosquito's body spun around in the air, aimed at the toad below, and was about to attack head-on!

"No! This toad looks like it's poisonous. ”

In mid-air, Jia Yan looked at the pimpled toad, and sighed unwillingly in his heart, but he still flapped his wings and flew away from this bush!

Even if the toad was not poisonous, such a disgusting creature, he didn't want to assassinate it.

He doesn't eat meat, and there's no good in killing him, right?

"It seems that I will try to see if my body is resistant to toxicity in the future, but mutation is not omnipotent, even if the body has resistance, it is impossible to be immune to poison."

The sound of mosquitoes flying is heard far away in the underground space.

In fact, this space is only about five kilometers long and wide, and if Jia Yan flies as hard as he can, it won't take long to fly from one side to the other.

But instead of doing so, he kept patrolling the sky.

"On the ground over there, there seem to be items from the human world!" It didn't take long for Jia Yan to see something shining on the ground.

He flew over.

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

This is a mirror, the surface is phosphorescent and shining, even after many years, it can still reflect Jia Yan's mutated hideous mouthparts very clearly.

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

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

The humans were dressed in military uniforms and armed with guns and ammunition. But there are a lot of terrifying huge creatures in this underground world, and Jia Yan can come and go freely now because he has the advantage of flying.

On the other hand, if humans advance on the ground, there is a high possibility that they will be killed if they encounter giant creatures.

Of course, for humans with thermal weapons, it may be that the average giant creature is not 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's the toxin in the air!

That's right, Jia Yan has thought about it, although he guesses that the air in the underground world is the key factor in the enormity of animals, but for humans, it is not necessarily such a good thing.

It's not even going to be an easy place for many creatures to survive.

So the scene of decades ago, Jia Yan can roughly deduce it.

The human team that managed to kill some of the gigantic creatures was poisoned one by one because of the toxins in the air. In the end, in the process of escaping to the cave, a large number of them died on the way!

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

Immediately afterward, the factory appeared above the crack that connected to the cavern. And then the war broke out in factories and other places! ”

"It was directly forgotten and abandoned for decades, until it was reopened by the Siberian Tiger, using some means. This...... It must be the whole process of the incident. ”

Jia Yan felt that his guesses were not far from ten.

Buzz.

He's still flying in the air.

Sometimes there are even some huge creatures below, attacking him as he flies up to 10 meters!

A bug that looks like a kowtow insect, but its body is hundreds of times larger than that of ordinary kowtow insects, this guy thought that Jia Yan had invaded his territory, and when Jia Yan flew over its territory, his head hit the ground, and his body instantly ejected, crashing into Jia Yan flying in the air!

Jia Yan naturally dodged easily, and this kowtow insect didn't even touch a single hair of him.

The number of creatures here is huge, but for some reason, the food source is also extremely abundant.

At least that number of creatures can thrive here.

They are aggressive, not to mention carnivorous animals, even vegetarian creatures like kowtow bugs, are tyrannical!

"I don't know if it's due to the special air and environment here, but I have to pay attention......

Jia Yan felt that it was necessary to control his abusive and killing impulses, otherwise what difference would he have with these wild creatures?!

Just as Jia Yan continued to explore this world.

"What's that? Is it another human object? ”

A thing lying on the ground, almost half 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.

The serpent was clearly a cobra species, but its body was a green green, very similar to the color of the plants.

Jia Yan looked at it hesitantly, and buried the human object less than five meters away from the giant snake.

He's thinking about whether or not to go down and investigate the object!

If it's a mirror or a rotten helmet, there's no need to risk it. Because no matter how you look at it, that giant snake is not easy to provoke......

"It doesn't seem like a mirror or a helmet or something, it's ...... A notepad?! ”

In Jia Yanfu's eyes, his eyes are faint!

Notepad, then there is really a need to risk snatching it!

Because this kind of notepad is generally used to record some important events. Especially if the human beings are soldiers, maybe it will be a more official record.

If there are some secrets recorded on it, or any other important things that these humans have discovered here, it will be of great help to Jia Yan.

Though...... Jia Yan didn't know Chinese or anything.

However, the script of the Wa Kingdom has been influenced too much by the Chinese language, and a large part of it is in the Chinese language, and even if you guess the words of the Meng, you have a great chance to guess what it means!

Thinking of this, Jia Yan made a decision!

The sound of his flight had long aroused the vigilance of the green cobra below.

At this time, the muscles of this big snake at seven inches spread, like a pair of small wings, and the snake's mouth emits a 'hissing' sound, constantly spitting snake letters!

This is a threat to Jia Yan!

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

Jia Yan flew towards this big snake!
