In the midst of his hesitation, the sound of percussion was heard again, this time more clearly, muffled in the ventilation tunnel. All three of them put their ears to the wall of the passage and listened carefully, but heard nothing but the echo of the tapping.

Ah Qi made a forward gesture and slowly leaned towards the place where the tapping sound was made, with Qiu Shan and Liu Qi following closely behind. After climbing about ten meters, a passage appeared on the right, and it was from here that the sound of percussion came from. This passage was about the same as the previous one, more than half a meter wide, and it was dark and devoid of any light. When I listened closely, the original unhurried tapping suddenly disappeared.

Ah Qi made a gesture to Qiu Shan and Liu Qi, told them to stop where they were, and was about to drill into the passage, when Qiu Shan suddenly pulled his clothes. Ah Qi turned around and saw Qiu Shan make a pause gesture to him, stretched out his finger and pointed to the inside of the passage, and then put his fingers together and wiped it on his neck.

Ah Qi looked at Qiu Shan in confusion, not knowing what his gesture meant. Qiu Shan's temporary learning of sign language was limited, and it was inevitable that he would not be able to express his words at this time, so he stretched out his left hand and spread it out, wrote the word "volt" in the palm of his right index finger, and pointed to the inside of the passage.

Ah Qi saw the words written by Qiu Shan in a faint light, and when he recalled the tapping sound just now, he suddenly felt that it was not good. He quickly pulled a tube out of his bag, twisted the end, and threw it in. When the object rolled to the end of the passage, there was a "huh" sound from inside, as if someone was very surprised.

At this time, there was a muffled "bang" in the passage, and then a blazing white bright light was emitted, and the entire narrow passage turned into a white light, only to hear a few exclamations from inside, and then a "bang" sound, as if someone had fallen into the room.

Ah Qi pointed his hand to the west, made a retreat gesture, and the three of them quickly crawled to the west with their hands and feet. About ten meters away, suddenly a few rays of light swept from behind, and several muffled voices shouted "stop" from behind.

Qiu Shan was at the back at this time, and when he looked back, he saw three figures crawling quickly along the passage wall. He hurriedly followed Liu Qi and crawled forward desperately. Ah Qi stopped, waited for them to catch up, and said in a deep voice, "You guys go first." ”

At this time, the three figures were only five or six meters away from them. He grabbed Liu Qi's arm and whispered, "They're about to catch up, let's retreat first." ”

Liu Qi gritted his teeth and moved forward, and Qiu Shan followed closely behind Liu Qi. The two of them climbed out of ten steps, and suddenly there was a low shout from behind, Qiu Shan and Liu Qi looked back, only to see the figure shaking in the staggered lights, and Ah Qi had already exchanged hands with the other party. This passage is only a little more than a meter high, and the width is no more than two meters, and the kung fu of dodging and moving in the fight is completely useless, all close to the grappling kung fu of the body, plus there are many people on the other side, I don't know if Ah Qi can withstand it.

Qiu Shan pushed Liu Qi's ass and said, "You go first." As he spoke, he turned around and crawled towards Ah Qi.

Ah Qi was stretching out his foot and kicking the head of a person on the left at this time, and the man let out a muffled snort and fell to the ground with a "bang". The man in the middle suddenly pounced like a toad, and Ah Qi rolled over and lay down, and quickly passed his elbow between the man's hands with his backhand, hitting him on the chin. With a "bang", the man was knocked to the back of his body, his head hit the wall of the passage above, but his hands clasped Ah Qi's right arm and pressed it under him. Seeing this, the man on the right punched Ah Qi's door, and Ah Qi's right hand was suppressed, so he had to turn around and stab his left fist diagonally into the man's fist. The two fists collided with each other with a "poof", and the man withdrew his hand in pain, and the other hand reached out to twist Ah Qi's left arm, and at the same time performed a grappling technique, twisting Ah Qi's left wrist joint.

Qiu Shan had come to the front at this time, and when he saw that the three of them were twisted together, Ah Qi couldn't move, so he kicked the head of the person on the right with his foot, and the strength of the man's hand was slightly loose, and Qiu Shan then kicked wildly. Ah Qi took advantage of the situation to break free of his left hand and punched the man in the neck, and at the same time retracted his foot and slammed his knee into the waist of the man in the middle, and both of them lay down softly.

Liu Qi's shout suddenly came from the front, Qiu Shan and Ah Qi looked up, but Liu Qi's figure was no longer visible, and there was a rolling sound of "dong dong dong" in the passage. The two of them were surprised, and hurriedly climbed over to take a look, and it turned out that the passage suddenly went down here, forming a long and large slope. Liu Qi just cared about climbing forward, and accidentally rolled down the slope.

Qiu Shan and Ah Qi also lay down on their sides and rolled down the slope. After rolling for about ten seconds, Qiu Shan felt dizzy and dizzy, and bumped into a body with a "bang", only to hear Liu Qi's scream of "ah", and Ah Qi also bumped into it behind, and a grille in front of Liu Qi couldn't bear it, and was knocked off with a "pop", and the three of them fell down at the same time.

In a "bang", Qiu Shan and the others fell into a pile of plastic foam cardboard boxes. Qiu Shan wiped the scraps of paper off his head, turned on the flashlight and looked around, and found that it was a large and tall room. The room may still be under construction, with a few scaffolding, and a few miscellaneous materials and packing boxes in the open space. Just now, the three of them smashed through the airlight of the passage, but fortunately they only fell on a large pile of cardboard boxes.

The three of them stood up and were about to find an exit when Liu Qi suddenly pulled Qiu Shan's sleeve and looked at a corner in the dark. Qiu Shan followed Liu Qi's gaze, and saw a pair of eyes staring at them in the dark!

Qiu Shan hurriedly picked up the flashlight resting on the ground and shone it into those eyes. A dark shadow suddenly flashed, dodging the flashlight and rushing towards him, with an extremely fast speed. Before Qiu Shan could react, Ah Qi next to him suddenly rushed to the front of Qiu Shan, met the black shadow head-on, and in the blink of an eye, the sound of six or seven fists and feet intersecting sounded like a cannon. Qiu Shan hurriedly aimed the flashlight at the figure, there were many shadows in the light, and the two were already entangled together, and they couldn't tell which was higher and which was lower for a while.

At this time, the shadow jumped on the scaffolding, suddenly flipped upside down, and kicked out in the air, Ah Qi just threw himself next to the scaffolding, and the back door was wide open. Saying that it was too late, he rolled away, barely dodging the attack, grabbed the steel pipe on the scaffold with both hands, and swept his leg sideways with a whirlwind, just in time to kick the shadow that had not yet landed.

The shadow snorted, flew diagonally two or three meters away, and fell to the ground with a "bang".

Qiu Shan took a flashlight, and the figure lying on the ground was the black-clothed young man he saw in the courtyard just now. He jumped up from the ground suddenly, but pounced directly at Liu Qi. Liu Qi was so frightened that he ran away, and the other party rushed behind him quickly, leaned forward, and greeted Liu Qi with a slap on the back of the head. Ah Qi caught up from behind and stretched out his arms to hit the man in black. Unexpectedly, the man in black leaned forward with his left foot, landed on the ground with his left leg as the axis, and his body swirled to the left, and a fierce elbow hit Ah Qi's head. Ah Qi's body was knocked to the side, and he fell straight to the ground with a dull sound. The man in black took advantage of the situation and punched Liu Qi on the side of his face, Liu Qi fell down with a "plop", and lay motionless on the ground.

Qiu Shan took out the gun from his pocket and was about to pull the safety bolt when the man in black suddenly strode forward, bowed forward, and hit Qiu Shan in the chin with an uppercut. Qiu Shan only felt that his throat and eyes were sweet, his mouth was full of blood, his chin was tilted to the side as if he did not obey the call, his head was dizzy, his body staggered back several steps, he fell on his back, and the pistol could not be grasped and fell to the ground.

Qiu Shan's ears were buzzing, and in the haze, he saw Ah Qi rushing forward and punching at the man in black, the man in black turned around and kicked sideways, Ah Qi opened it with his hand, and the two fought in one place again. Qiu Shan felt dizzy, and vaguely saw that the two black shadows were indistinguishable from each other, and finally they both fell to the ground, and the low shouts and fists and feet stopped, only to occasionally hear one or two muffled snorts.

Qiu Shan groped for a flashlight on the ground and went to Ah Qizhao, only to see him and the man in black intertwined hands and feet, and the two of them rolled on the ground like twisted flowers, with hideous and painful expressions on their faces. From time to time, Ah Qi was beaten on the waist by the man in black, and his mouth let out a muffled snort or two, while his hand twisted one of the elbows of the man in black, occasionally tapping the back of his neck.

Qiu Shan raised his body and saw that Liu Qi was still lying on the ground, so he quickly reached out and touched his carotid artery, and only then was he relieved when he saw that the pulse was beating normally. He struggled to get up, picked up the pistol, and walked towards Ah Qi in three steps. The man in black seemed to sense the danger, and slammed Ah Qi's waist with all his might. Ah Qi grinned, but still tightly clasped the elbow joint of the man in black.

Qiu Shan walked up to the man in black and saw that this man had dark skin, his face was covered with sweat and dust, and he couldn't see his face clearly. When he saw Qiu Shan holding a pistol, there was no fear in his eyes, but instead he showed a violent and murderous gaze. Qiu Shan was shocked by the murderous aura in the eyes of the man in black, but when he saw Ah Qi's painful expression, he mustered up the courage to smash the butt of his gun at the man's head.

The gun slammed into the man in black's head, smashing his head crookedly to the side. Unexpectedly, the man in black straightened his head again and continued to stare fiercely at Qiu Shan. Qiu Shan's heart was horizontal, and he suddenly picked up the gun and smashed it down, smashing it seven or eight times in a row, and the man in black slowly loosened the strength on Ah Qi. Ah Qi broke free and took advantage of the situation to strike a horizontal elbow on the temple of the man in black. The blow was so swift that the black-clothed man rolled stiffly to the side, lying motionless on the floor, as if he had fainted.

After the vicious fight just now, Ah Qi was exhausted and lay on the ground gasping for breath. Qiu Shan quickly walked to Liu Qi's side, broke his body, and saw that Liu Qi's face was covered with blood, so he hurriedly wiped off the blood stains with his sleeves, shook his shoulders and shouted: "Liu Qi, Liu Qi." ”

Liu Qi slowly opened his eyes and said vaguely, "I...... I almost didn't catch my breath just now. ”

Qiu Shan saw that half of Liu Qi's cheeks were red and swollen, and asked, "Are you okay?" ”

Liu Qi nodded.

At this time, Ah Qi stood up and said, "The other party may come at any time, so you have to leave here quickly." ”

Qiu Shan hurriedly stood up and found an iron door on the west side of the room, which was dotted with welding rods, which should have been built temporarily during construction. He pushed open the iron gate and saw an unfinished corridor outside, about ten meters long, with a bare concrete frame, large pieces of stone bricks stacked in stacks, and some building materials such as scrap bricks and scrap iron wire on the ground. At the end of the corridor is a construction freight elevator.

Qiu Shan turned back, picked up Liu Qi with Ah Qi and came to the freight elevator. The three of them walked into the freight elevator, and after Qiu Shan pressed the button, the freight elevator went up, and it reached the ground in a few moments.

The group stepped out of the freight elevator and found themselves in a hall. The hall was empty, and there was a large iron door on the south side. They went to the iron gate, and when they saw that it was not locked, they pushed it open and walked out. When I came outside, I realized that this was a construction site, surrounded by several high-rise buildings full of scaffolding, and a giant crane stood in the dark construction site, only a headlight not far ahead gave a miserable white light.

"This is Afangyuan, Liu Dengji's real estate project." Ah Qi said.
