Chang Fa didn't know what this voice was, but Zhang Yancheng knew it completely.

In fact, there are many mechanisms in the corridor in this cave, in order to prevent outsiders from intruding, and this sound is a kind of mechanism.

It's not a so-called Dark Arrow Trap, it's not a quicksand trap, it's not a poison invasion, it's a bunch of biological traps.

The source of this buzzing sound is a group of small insects that have been kept in captivity in this corridor.

These insects are scavengers who live in the tunnels all year round, and only a small number of insects usually leave to feed, and most of the time they sleep in the burrows.

Until a mechanism outside is triggered, these bugs will wake up at the beckoning of some strange sound, and then go out en masse, wandering back and forth in the corridor for a long time.

These bugs crawl on the ground, they have wings, but they can't fly, and they make this buzzing sound when their wings vibrate.

According to the analysis of Zhang Yancheng's clansmen, these insects were actually responding to the sound of calling them out when they vibrated their wings, so as to determine the location of both sides.

But there is no definite answer as to why this behavior occurs.

These insects generally do not eat living people, they only eat carrion, so they are generally not very dangerous.

But one or two are okay, and it can still be dangerous when you meet a group because they bite people.

They don't eat people, but when they see them, they take a bite, taste them, and they say, oh, they can't eat them!

The bugs in the back will also be the same as the previous one, take a bite first, taste it, and sigh, oh, can't eat it!

Then the insect tide passed, and the person was basically bitten into minced meat.

These things have not happened before, since Zhang Yancheng's family has designated this place as a clan land, they still know the situation here relatively well.

They have also faced these insects many times, and there are some ways to avoid the insect tide, but it is best to escape as soon as possible in this environment.

Zhang Yancheng quickly woke up the fat man and Li Jiao, and he shouted to run without explanation.

The fat man and Li Fake reacted extremely quickly, and when they heard Zhang Yancheng's shout, they didn't hesitate at all, grabbed the package on the ground and ran back.

Chang Fa discovered the danger earlier than them, but the reaction speed was a little slower than them, and he fell to the end in a blink of an eye.

The road is relatively wide, nearly two meters long, so the four of them can run forward even if they are shoulder to shoulder.

The fat man is relatively wide, but his speed is not slow at all, he carries a kerosene lamp in the front, followed by Li Jiao, and then Zhang Yancheng and Chang Fa side by side.

The cave is relatively dark, except for people like Chang Fa and Zhang Yancheng who have strong eyesight, Li Jiao and the fat man don't dare to run too fast, for fear that they will hit the wall in front of the hole.

A moment later, the rustle of bugs was not far behind.

"I'm going to be overtaken!" Chang Fa said anxiously.

He didn't know what was behind it, but the rustling sound was so terrifying that he was furious when he heard it.

Zhang Yancheng glanced back. First issue ╭ァんttps://.cΘmヤ

The back of the cave is still dark, and the color of the insects seems to be black, so it is not clear at all.

Not only Zhang Yancheng couldn't see clearly, but Chang Fa couldn't see anything clearly at all, just listening to the sound, he could feel that behind him was the sound of arthropods crawling on the ground with multiple paws.

After running for nearly ten minutes, the voice behind him became clearer.

Chang Fa turned his head and could already see the source of the sound, which was a large area of insects, or a black insect tide, and the tide was constantly surging forward, densely packed.

Each bug was as big as the bottom of a beer bottle, grayish-black, with three pairs of claws and a pair of chelates.

The most astonishing thing was the bug's strange head, which had a large mouth, nearly half the size of its body, and its teeth were white and shiny, giving off a cold glow.

When the insect crawled, not only did its wings flap and make a sound, but its teeth also kept tapping up and down, making a clattering sound.

And the speed of this insect crawling is so fast that a few people can't outrun them in this dark environment.

In fact, Chang Fa and Zhang Yancheng can run away, but it is impossible for them to leave the fat man and Li Jiao here, and there is another point, even if they run back to the exit, they still need time to throw the rope up, and then climb up.

Whether it will be possible to leave smoothly is another matter.

After running for a few more minutes, the tide of insects was almost five meters behind them, and now not only Chang Fa and Zhang Yancheng, but also people with ordinary eyesight like Li Fake Fat Man could see what was behind them.

The sound of insects crawling on the ground is like a wave of whizzing cars on the highway, constantly ringing, noisy and often panicking.

"Plug your ears!"

Chang Fa shouted, then raised the rifle in his hand as he ran.

At this time, the effect of hitting the insect tide behind with a gun will be very obvious, and it is definitely a bullet that can run through a long line, but at this time, the effect of a few bullets will not be particularly large, there are too many insects.

Seeing that everyone blocked their ears, Chang Fa hurriedly turned around and shot at the insect tide behind him.

In this case, there is no need to aim, and a random bullet can hit a large number of targets.

Chang Fa fired a strafing shot and fired a half-shuttle bullet, and the insect tide behind him immediately opened a few gaps.

But it's like a bullet in water, and although there is a gap for a while, it will disappear in an instant.

A surprising scene occurred.

After the explosive gunshots rang out, several people were shocked to their ears, and Chang Fa used the spiritual qi in his body to turn around a few times before recovering.

And because after the gunshot, everyone couldn't hear the sound clearly and was just running with their heads down, so they didn't hear the anomaly behind them clearly at all.

After the gunshot, the insect tide behind him suddenly stopped, and then, as if stimulated, they turned around and began to run back.

During this period, some insects reacted slowly, did not turn in time, and were even bitten into pieces by the swarm of insects behind.

Chang Fa's hearing recovered and ran forward for a while before he realized that something was wrong, he looked back, and the insect tide chasing behind him was gone.

There are only some scattered debris left on the ground in the hole behind him.,There was a fishy smell.,That's the corpse left by the bug that didn't have time to react was torn apart by his companion.,It looks particularly cruel.。。 Genius remembers m.

Chang Fa immediately called out to Zhang Yancheng and the others, and he also took the lead in stopping and looked at the back carefully.

Indeed, all the bugs had run away, and when the fat man returned with the kerosene lamp, everyone could see more clearly, and all that was left on the ground was the scales of the dead bugs, and the scattered internal organs of the bugs.
