The sound is very strange, like a bee or a mosquito, it is very strange, and when it comes to it, it is like an electric wave, which makes people feel uncomfortable.

No matter what strange things happened in the secret passage, Ye Feng didn't feel strange, because it was too unusual here. First I encountered bats when I first arrived, then there was a sudden earthquake, and now there is this strange sound.

Ye Feng knew very well that none of the things that could appear in such a place were simple, so he would not let his guard down at any moment.

"Buzz! Buzzing! ”

The voice became clearer and clearer, and it seemed to be getting closer and closer, as if ringing in his ears, making Ye Feng's face even more pale, and his body was a little stiff..... Suddenly, he shuddered as he realized that the sound seemed to be coming from behind him, in the lab.

Could it be .....?

Ye Feng involuntarily turned around, only to see black wriggling creatures suddenly appear on the ground not far away, the creatures looked very small, only the size of a few little fingers. But the terrifying thing is that such foreign objects are a group of them, and they are still emerging from the ground in a steady stream, and in the blink of an eye, there is darkness ahead.

No.

Not darkness.

Instead, dense black wriggling creatures covered all the colors around them. Therefore, at first glance, it seems extremely dense, and people can't help but have a deep sense of fear.

Even Ye Feng couldn't help but gasp when he saw this scene, good guy, what are these things? If the previous group of bats made Ye Feng shocked and shuddered, then the black creatures all over the ground made Ye Feng's scalp tingle, and fear also grew in his heart.

The whole person involuntarily took a few steps back.

There are too many of these aliens, and Ye Feng can clearly see what they look like.

Dressed in black visor, it has two scissor-like cones on its head, and its dark eyes show a row of sharp teeth at its jaw.

Such a strange creature, Ye Feng can be said to be unheard of, don't say that he has seen it, even if he has heard it, he has never heard of it.

"Weng Weng, Weng Weng."

Strange noises erupted from their mouths, so numerous that they echoed around. Not only on the ground, but also on the walls and ceilings, there are almost all these black creatures, and I don't know where they came from.

As soon as Ye Feng retreated, he had already retreated to the wall. Although these black creatures are numerous, they don't crawl fast. Suddenly, Ye Feng seemed to remember something, and hurriedly ran to press the switch.

Thundered.

Driven by the switch, the huge rusty iron gate shook like a mountain peak, the ground trembled slightly, and a lot of rubble around it also rolled down wantonly because of the trembling.

Seeing that the group of black creatures was about to jump over the iron gate, but with a bang, the iron gate ruthlessly isolated the group of black creatures inside.

Seeing the iron door closed, Ye Feng breathed a sigh of relief, it was really dangerous just now, if this was rushed out by that group of creatures, who knew what kind of disaster it would cause.

Although Ye Feng didn't know how terrifying they were, from the perspective of his eyes, these guys were definitely worse than those bats.

Since the group of black creatures was locked inside, there was no need for Ye Feng to stay here. Raising his feet, he was about to leave, but as soon as he took the first step, he suddenly stopped, his face twitched for a moment, his eyes contained strong shock and disbelief, he held back the trembling in his heart and turned his head away.

I saw the iron door slamming and banging, as if something was banging heavily on the iron door, which was very strange.

If only that's all.

What made Ye Feng feel most incredible was that there were also uneven pits on the iron gate, and as the sound became heavier and heavier, there were more and more of these pits.

"Damn."

Ye Feng never thought that these guys were so terrifying, even something like the iron gate could be forcibly broken through. Thinking of the next scene, Ye Feng's body trembled, took a deep breath, suppressed the horror in his heart, and hurriedly retreated.

Looking at the appearance of the iron gate, I am afraid that it will not be able to support it for too long, once it is broken, those black creatures will not only be a danger to Ye Feng at that time, but also may break out of this secret passage.

After all, they can even break through the iron gate, and the secret passage is naturally no exception.

Therefore, Ye Feng had to find a way to destroy all these creatures, and he must not let them run to the ground.

And the best way to deal with this creature is to attack it with fire, just pour oil down and then ignite the fire, and you should be able to destroy these guys.

But the premise is that these flames will not be burned together with the passage mouth, if you want to completely kill them, the firepower cannot be small at all, but if it is big, Ye Feng is worried that the passage mouth will not be able to withstand it.

You must know that the passage mouth is connected to the teaching office, and once the passage mouth is really burned, then the teaching office will inevitably be affected, so you must find a way to get the best of both worlds, both to destroy them and to reduce the firepower.

Well!

Ye Feng was suddenly stunned and stopped, yes, how could he forget about that group of bats, if you let those bats and those guys fight, you can not only reduce the number of black creatures, but also reduce the number of bats, this is completely killing two birds with one stone.

Ye Feng's idea is not bold, nor is it unnovel.

At the risk of being attacked by bats, he had to lure them to the monsters and let them kill each other while he profited.

With that in mind.

Ye Feng acted immediately.

Rumble.

There was an earth-shattering sound from behind, and Ye Feng knew that the iron gate had been broken, and since it was broken, it meant that there was nothing to stop them.

Ye Feng didn't look back, he quickened his pace, although there were many forks in the road around, Ye Feng's memory was super high, and the future route was clearly engraved in his mind. So it didn't take too long to reach the realm of the bats.

Really.

When Ye Feng came to their realm, the sound of "squeaking" came into his ears, and soon, a group of bats appeared in Ye Feng's sight, and his blood-red eyes looked particularly terrifying in the darkness.

Seeing the bat appear, Ye Feng fled backwards again, and his escape route was also the place of black creatures.

But something unexpected happened to Ye Feng.

After running for a while.

He found that the bat behind him was missing, what was going on?

Immediately, as if he realized something, Ye Feng's face showed a surprised expression, could it be ..... Are bats scared of that bunch?

This......

Ye Feng was a little incredulous, and then, he remembered that the group of bats before had also disappeared suddenly, and at that time he was still guessing why, but now it seems that the bats are actually afraid of them.
