They were first attacked by a puff of black smoke, which came out of nowhere and could change into various shapes, and it was this time that Professor Li was swept into the air by the black smoke and turned into a mess of meat.

It's like something out of a mythological movie.

Then he was grabbed by an invisible hand that came out of the floor, and then something resembling a shadow came out and tore the two SWAT officers apart.

The third time they were attacked, it was when they came to the second floor, and this time what attacked them could be seen, some big flies that could fly. These are colorful flies, buzzing and attacking people, and wherever they bite, they are a blur of flesh and blood.

This time almost all of them were injured.

In a hurry to escape, he accidentally rushed into this secret room.

Fortunately, hiding in the secret room, those things outside would not rush in, which made them feel very incomprehensible, but they couldn't care so much about it in such an embarrassment.

When they fled for their lives, Professor Hu and his entourage lost a lot of equipment and materials, which caused them to be unable to treat their wounds in time, and they had no food or water in the house.

That's hunger and thirst.

By the time we arrived, Professor Hu and the others had been hiding in the stone chamber for more than twelve hours.

I don't know what the reason is, but only a dozen hours have passed, but their hunger and thirst at this time are as if they haven't drunk a sip of water or eaten a mouthful of food for three days.

It must be due to the special environment here.

After briefly describing his own experience, Professor Hu asked us, "You weren't attacked by anything along the way?" ”

Haoyu shook his head: "I just saw something strange......"

He gave a brief account of our experiences along the way.

The atmosphere in the entire stone room suddenly became very oppressive.

"The priority is how to get out of here!" Director Hu slowly stood up and coughed twice before speaking in a low voice.

"Yes! I don't know what those things are outside......" Professor Han didn't finish his words, and was picked up by the old glasses on the side.

"You said, we have been attacked three times by unknown things, why are they okay Xiao Liu? This is probably not a coincidence! ”

This made the room fall silent again.

"Let's comb it carefully!" In the end, it was Haoyu who opened his mouth to break the silence.

"How to comb?" Old glasses asked rhetorically.

"You think! Those things outside attacked Director Hu and them three times in a row, but they never attacked us, and there are two reasons that can't be ruled out, one is that those things outside don't dare to attack us, but they don't want to. ”

After Haoyu finished speaking, everyone looked at him and nodded slightly.

"Let's start with the first scenario......

If they didn't attack us because they didn't dare, then it wasn't what we brought with us that they should be afraid of, but someone among us.

Haoyu paused for a moment before continuing, this person should be Brother Lu Dong.

In the second case, it would be very scary to think about.

It shows that the things that attacked Director Hu outside have thinking, and they can even "make suggestions", they deliberately did not attack us, and the purpose was to lead us to this secret room, which is very similar to the "catch alive" that often appears in TV dramas...... Then it's very complicated. ”

After discussing for more than half an hour, I didn't come up with anything.

But just when everyone was at a loss, suddenly there was a rush of footsteps outside, followed by a strange crackling sound, as if it was a drop of something, and it seemed that two groups of people were fighting, and they were still fighting.

Sounds are getting noisier and more complex.

It seems that there is something else called, and the sound is similar to the sound it made when I was a child when I caught Yellow River eels in the mud of the Yellow River.

After another five or six minutes, everything was quiet.

All of a sudden, it was terrifyingly quiet.

"What's going on out there?"

Director Hu broke the silence with a soft shout.

"Looks like someone is coming again!" Haoyu pressed his left ear to the stone door and listened for a while before replying.

"Could it be that Director Li is not at ease and has increased his support?" Director Hu also put his ear to the stone door and listened, while muttering in his mouth.

"It's not like that! If it were one of us, he would definitely want to contact us - and the voice just now seemed to be ......"

The atmosphere suddenly became depressed again.

Needless to say, it's definitely not ordinary people who can come here, and it's either friend or foe, and things seem to be even more tricky.

But at this moment, there were three rhythmic knocks on the door outside.

"Pap-papa-papa"

My scalp exploded, and then I reacted: This is someone knocking on the stone door!

Except for me, Haoyu reacted the fastest.

He took two steps back and made a "silence" gesture to everyone, and everyone understood and stood motionless.

This was followed by three rhythmic knocks on the door.

"Pap-papa-papa"

And then came an old and hoarse voice.

"If you don't open the door, we'll leave!"

It was a man's voice, an old man to be exact, and it sounded familiar to me.

Haoyu still shook his head at everyone, signaling everyone not to make a sound.

After saying this, there was silence outside, and after waiting for more than a minute, the sound of footsteps gradually moving away sounded.

I don't know if Haoyu can hear clearly, anyway, with my ear, I carefully distinguished, and I could hear about four or five people hearing footsteps outside, and I heard that these people had already walked away.

This makes me even more confused.

It must be someone from outside, and it stands to reason that if it is a person, it should be the one that Director Hu said just now that their superiors sent to support - but in fact, it is definitely not...... And it was obvious that Director Hu and Haoyu were not familiar with the voice just now, and they were even more sure that it was not their people.

Who would be here if it wasn't their people?

The key is that there are always a few special police officers who have grabbed nuclear bombs around the hole on the ground, and outsiders can't get in?

The hoarse old man's voice was mixed with ...... It's so familiar! I'm sure I've heard it somewhere.

The brain flashed like a marquee to the old man who had been in contact during this time, and suddenly his scalp was numb, and I remembered, isn't this the voice of Li Chunfeng, the ink artist who took me to the underworld of the Yellow River that time!

Li Chunfeng's voice is unique, with a taste of gongs and drums, and it is difficult for ordinary people to imitate it.

So it's the ink that comes out there?

These thoughts came to my mind, and my heart was filled with joy.

"I know who's out there!"

"Oh?"

"Who is it?"

I shouted in silence, like a bolt from the blue, and everyone blinked at me.
