The system is the king of the counterattack master

"Damn! What!"

The sound of knocking on the door was very loud, which scared Duan Muxiu into a shiver, and took several steps back.

Han Xiaodong was also taken aback, but he was already prepared for strange things to happen when he played that weird recording, so he was somewhat psychologically prepared for this sudden change, and he was not as violent as Duanmuxiu's reaction .

He turned his head to look at He Xi, and found that He Xi was also quite frightened, with both hands on his chest, the expression on his face was terrified, and the flashlight even dropped to the ground.

Thinking about it, such a reaction is nothing but normal. In a quiet and dark corridor, behind a completely unknown door, something suddenly made such a loud noise, and the two of them didn't turn around and run away, which already shows that they are brave enough .

Han Xiaodong made a silent gesture to Duanmuxiu, reached out to pick up the flashlight on the ground, put it back in He Xi's hand, patted her on the shoulder, turned and walked back to the sliding door.

There was only one ring, and the loud voice disappeared. Han Xiaodong took out his mobile phone again, turned around and glanced at the two people behind him, signaling them to get ready, and he wanted to play the recording again.

Although He Xi and Duanmuxiu were still terrified, they still nodded, indicating that he could continue. Han Xiaodong saw that Duanmuxiu had already held the gun in his hand. As long as there were any changes that stimulated him, he would probably Nine will actually shoot.

Pressed the play button again, and that tooth-piercing sound came out from the phone's speaker again, this time it didn't take long, and there was another loud crashing sound from the door, and this time the sound was obviously It was no longer issued by one thing, it seemed that several leather hammers were hitting the door like raindrops at the same time.

Duanmuxiu and He Xi took several steps back one after another. Duanmuxiu had already raised his gun, his hands and legs were trembling. Obviously it wasn't Xueqing and Zhou Hao inside, but something else wanted to go outside. rush.

For a moment, the passage became very chaotic. The eerie ringtone from the mobile phone and the frantic banging sound from the door followed one after another, causing a kind of panic that seeped into the bones.

Han Xiaodong looked at the door and didn't move it. The sound inside was ringing crazily all the time, but the things inside seemed to be unable to come out at all. The iron door was not difficult to open, but the things inside the door were just hitting. But they didn't pull the door. It can be seen that these things should have no IQ. In other words, they are not human in all likelihood!
Since they couldn't come out for the time being, Han Xiaodong was relieved. He turned his head and pressed Duanmu Xiuxu, signaling him to put down the gun. If the contents didn't come out, he would let the nervous Duanmuxiu shoot the gun again. Injury or death is not cost-effective. This kind of confined space is very deceptive. If the bullet misses the target, it will ricochet. Who knows what accidents will happen then.

Han Xiaodong still played the strange recording, but put his face on the iron gate.

This is a new skill he has learned this year. Through the reflection of the sound, he can judge what the invisible place looks like. This skill is a bit like a bat using ultrasonic waves to locate objects. The difference is that he does not need to emit ultrasonic waves himself. Just listen to the sound reflected in the room.

Theoretically speaking, as long as one sound source is placed in a room, and that sound source is enough to touch the farthest wall in the room, Han Xiaodong can outline the shapes, boundaries, distances, and even materials of all obstacles in the room. .

Lying on the door and carefully analyzing the situation behind the door through the sound, Han Xiaodong became more and more frightened the more he listened.

Behind that door is an extremely complex space, its size is astonishingly large, there are not only a large number of equipment and partitions, but also forty or fifty movable humanoid things, and now there are nearly twenty of them gathered at the door, and there are Thirty or so were slowly moving towards the door. Their speed was very slow, but their goal was very clear, and they were running towards the voice in their hand.

The dozen or so guys inside the door crowded and piled up to the door, but the sound inside the door was not caused by their banging on the door with their hands, but by hitting their heads. Based on this sound, it is not difficult to know the identity of the thing. How hard the head is.

Han Xiaodong roughly heard what was going on inside the door, pressed it lightly, and turned off the phone's ringtone.

As soon as the bell stopped, the moving figures also stopped, and there was no sound in the room. He didn't know where Zhou Hao and Xue Qing were, but he could roughly hear how many rooms there were in the room. It is estimated that the two of them are now It should be hidden in one of the rooms.

Han Xiaodong was a little worried. These ten or so human-shaped things were crowded at the door. As soon as the door was opened, they would rush out immediately. Therefore, this door cannot be opened no matter what, but how can they get in if it is not opened?
He suddenly thought of the time when he contacted Zhou Hao in the morning. Zhou Hao was very cautious at that time, trying not to speak, but using encrypted Morse code to communicate, presumably trying to avoid these monsters and try not to make a sound.

But what are these things?

He once experienced a trial field and saw living mummy, but judging from what he just heard, these things seem to be different from mummy, their movement speed is obviously much slower than that of mummy, and from the way of action , nor is it as flexible as a mummy.

But even so, he still didn't dare to take it lightly, what if there was any poison in these things?After all, there are Duanmuxiu and He Xi behind him, these two ordinary people can't afford any accidents.

While hesitating, Duanmuxiu came over: "How is it? What did you hear?"

Duanmuxiu's voice was very soft, almost out of breath, obviously afraid of disturbing those things behind the door.

Han Xiaodong frowned and glanced at him, not knowing how to explain it to him, the situation inside was really hard to describe.

Just when he was wondering how to explain it, there was a sudden change inside the door, and the humanoid monsters blocking the door began to move. Their front team changed to the rear team, turned around awkwardly, and then slowly started to disperse.

Han Xiaodong quickly put his ears on the door again, listening carefully to the movement inside.

"What's the matter? What did you hear?" Duanmuxiu saw that Han Xiaodong put his ear to the door again and didn't answer his own question, so he repeated the question just now.

Han Xiaodong covered his mouth with his hand and signaled him not to speak. The moving speed of those things was very slow, and the iron gate was relatively thick. If you didn't listen carefully, you couldn't hear them clearly.

After listening for a long time, Han Xiaodong let out a long breath until there was no more sound inside. Just about to explain to Duanmuxiu, he heard a clicking sound from He Xi's walkie-talkie behind him.

Hearing this familiar voice, both Han Xiaodong and Duanmuxiu were shocked, it was Zhou Hao!
