Qiu Shan stretched out his head to look down, and several people were gathering in the inner courtyard at this time, talking in a low voice. Liu Qi was about to speak, Ah Qi made a silent movement, and then tiptoed to the north sidebar. On the north side of the wing, there is a lower transept, about three meters away from the wing.

Ah Qi probed and observed, then walked back to Qiu Shan and Liu Qi and said, "I'll go over first." Then he sped up and rushed to the sidebar, slammed his foot on the railing, and jumped into the air.

Liu Qi's "ah" word was just about to be exported, but Qiu Shan held his mouth down. The footsteps on the other side of the stairs were getting louder and louder, and it seemed that the visitor had gone up to the second floor. Qiu Shan hurriedly dragged Liu Qi to the north side of the corridor. When he walked to the railing, he saw Ah Qi hanging under the eaves of the ear house, and shook the string in his hand at them.

Qiu Shan saw that there was a live buckle hanging on the sidebar, and Ah Qi had already tied the rope, so he whispered to Liu Qi, "You go first." ”

Liu Qi shook his head and muttered, "Brother Qiu, you're not joking, are you?" So high......"

"Hurry up, don't bother." Qiu Shan said, grabbed Liu Qi's hand and dragged him to the railing. Liu Qi had to grab the rope and hang it in horror to the side of the ear room. At this time, Ah Qi had already climbed onto the roof of the ear house, and when he saw him hanging under the eaves, he hurriedly grabbed his hand and dragged him up.

At this time, the two had already walked out of the staircase, and Qiu Shan secretly complained and curled up under the railing. The two didn't notice the corner of the corridor and walked straight to the room where Liu Qi was being held, still talking. Qiu Shan was not far away, and he vaguely heard one of the thin men say: "It's a pity that those two mastiff kings will die with two shots." ”

Another continued: "The five brothers were put down at once...... The other party is not small, and our brothers will have to be careful in the future. ”

The thin man touched the back of his neck and said with a sneer: "Brother Qiang, you are well-informed, and you will cover your little brother more in the future." ”

The humane called Brother Qiang: "Monkey, don't worry, what is our relationship?!" After a pause, he said: "The opponent Liu Tianshi encountered this time is very strong, and we will have to be clever in the future." ”

"I don't know where the other party came from...... Do you think that the Jade Tiger Mage's method can make this kid move? At this point, the two of them had reached the door, and the thin man took out the key and opened the door, and the two walked in.

"Hmm, the mana of the Jade Tiger Master is naturally nothing to say...... Hey? Brother Qiang seems to have discovered something wrong.

Qiu Shan took this opportunity to quickly grab the rope and quickly hang it under the eaves of the ear room, and as soon as he reached the eaves, he turned around and saw the thin man running out of the house, and shouted to the people in the courtyard below: "That kid has run away!" ”

Ah Qi grabbed Qiu Shan and pulled it onto the roof violently, crawling to the other side of the ridge. After climbing over the ridge, the trio climbed north along the slope.

Ah Qi stopped, pointed to the eaves not far away, and said, "You can go down from here." When the three of them came to the eaves, several bright lights suddenly lit up above the side wall, illuminating the open space outside the courtyard as if it were daylight.

Ah Qi said: "I can't go down, I have to find another way." As he spoke, he climbed back to the roof, and Qiu Shan and Liu Qi had no choice but to follow him closely. The three of them climbed up to the roof and looked into the courtyard, where it was already brightly lit. A young man in black was standing in the middle of the courtyard, surrounded by a group of people, and a muscular man was saying something to him. The sturdy man was followed by two people, one fat and one thin, the two people named Brother Qiang and the monkey just now.

The young man in black talked to the sturdy man for a few words, and then followed them towards the west wing.

"There's an exhaust outlet in the main room, let's go over there first." Ah Qi said and climbed along the ridge of the roof in the direction of the main house, followed by Qiu Shan and Liu Qi. The transept was connected to the roof of the main house, and the three of them climbed to the roof of the main house, feeling that the tiles were smooth, as if they were made of black glass, which was very different from the green tiles just now.

On the north slope of the ridge is a gray cylinder that looks like a chimney, but is much larger than a normal chimney. Ah Qi led the two to climb to the side of the cylinder, and everyone saw that the cylinder was about half a meter in diameter, bent into a semi-arc, and the opening was facing the back of the main house, and the mouth of the cylinder was covered with barbed wire.

"Strange...... Are you sure this is for exhausting? Qiu Shan looked at Ah Qi in confusion.

Ah Qi nodded and said, "I've been observing for a while, this is not a chimney." So saying, he removed the barbed wire, took out a bundle of rope from his pocket, tied it into a slipknot and hooked it around the edge of the cylinder, and then pulled the rope into it.

Qiu Shan and Liu Qi followed Ah Qi up and down.

The exhaust pipe wall is smooth and there is no dust, so I think it should be kept ventilated on weekdays. At this time, there was a cool breeze under the pipe, and although the space was cramped, it didn't feel stuffy. When he went down to seven or eight meters, Qiu Shan looked up and saw that there was only a little light above his head, and he didn't know how deep the black hole was below.

Liu Qi couldn't bear the strength of his hands and feet, so he slipped down with a "bang" and stepped on the top of the hill. Qiu Shan was trampled on and arched his body, pressed his knees against the wall of the tube, and said to Liu Qi with all his strength: "Lift your legs up and use your knees to push up both sides." ”

Liu Qi finally lifted his legs, his buttocks grinding on the wall of the tube "chirping", and his mouth couldn't help but "hum", obviously his knees and buttocks rubbing against the wall of the tube hurt.

Qiu Shan secretly thought that this quadrangle was only eight or nine meters high at most, and now it had dropped at least thirteen or fourteen meters, and it was said that it should have reached the ground a long time ago, but it was still a black hole below. He looked at Ah Qi, and when he saw that he was silent and descended down, he couldn't help but ask, "How long will it take?" ”

"Shhhh Ah Qi touched the wall of the tube with his fingers and whispered, then pressed his ear to it.

Qiu Shan hurriedly put his ear on the wall of the tube and listened carefully, and sure enough, there was a continuous sound of mechanical rotation faintly. After a few moments, the sound suddenly disappeared.

"Elevator?" Liu Qi asked in a low voice.

"Well, there seems to be an elevator shaft nearby."

"Don't speak, try not to make a sound." Ah Qi finished speaking and went down.

Liu Qi didn't dare to rub his butt against the wall of the tube anymore, so he had to clamp the rope with his legs, his hands were a little sore and weak, and he simply hugged the rope to his chest with both hands. In this way, the speed was much faster, and the inner thighs were sharpened by the rope, and they couldn't scream, and the expression on their faces became miserable.

After about another three or four meters of dropping, Qiu Shan heard a soft sound from below, and hurriedly looked down and saw that Ah Qi seemed to have stepped on the bottom of the pipe. At this time, Liu Qi's buttocks suddenly pressed on Qiu Shan's head, and it turned out that he couldn't support it anymore, so he sat down straight. Qiu Shan was pressed by Liu Qi's body, and suddenly felt unbearable, and his hands couldn't help but loosen, and the two of them fell to the bottom of the pipe together.

The pipe here is a bend, and the diameter of the horizontal section of the pipe is only more than half a meter, and the body cannot turn around. Qiu Shan complained bitterly, when he came in just now, he was on his head and feet, but now when he is lying flat, he is in front of his feet and behind his head.

"Climb backwards." Ah Qi's voice came from not far ahead. Qiu Shan turned his head to look at Ah Qi and saw that he had climbed two or three meters away.

Qiu Shan and Liu Qi both turned over, supported their bodies with their elbows and knees, and slowly moved back.

After climbing more than ten meters upside down like this, Qiu Shan turned his head and saw that Ah Qi had stopped, and there was a faint light behind him. At this moment, there was a crisp sound of metal crashing, and Ah Qi seemed to kick off something and crawled out of the pipe.

Qiu Shan and Liu Qi quickened their pace, and then drilled out of the pipe, and saw that there was a low square passage outside, less than one meter high and about two meters wide. The square passage divides into two paths not far ahead, one continuing forward and the other turning to the left.

Ah Qi beckoned Qiu Shan and Liu Qi to come to the fork and said in a low voice, "The passage should lead to some rooms, from now on, we will communicate with gestures." After Ah Qi finished speaking, he gestured with his hands, teaching Qiu Shan and Liu Qi simple gestures such as forward, stop, retreat, received, don't understand, and someone. After teaching the gestures, Ah Qi pointed to the left, Qiu Shan and Liu Qi made the received gestures at the same time, and the three of them crawled to the left.

After about two or three minutes of crawling, Ah Qi made a stop movement, and then put his ear against the wall of the passage. Seeing this, Qiu Shan and Liu Qi also listened carefully with their ears close, and sure enough, they heard a sound coming along the wall, and the sound was erratic and unrecognizable.

The three of them crawled out of a dozen or so steps, and Ah Qi's movements became slower and slower, and finally stopped. At this point, they came to a fork in the road, and the passage on the left looked just over half a meter wide. Ah Qi slowly climbed in, and seeing that he was so cautious, Qiu Shan and the two of them also held their breath and gently climbed inside. After only three or four steps, the three of them saw a grate not far in front of them shining light, and they faintly heard the sound of someone talking.

Ah Qi reached behind him with his left hand, put his fingers together and made a stop gesture, and then gently crawled towards the grille.

This grille is on the left wall of the square exhaust channel, and the light shines from inside, forming more than a dozen faint gratings, and the human voice seems to come from below.

Ah Qi climbed close to the grille and saw that the lattice was obliquely inlaid, obscuring the light in the room, but the human voice was already clearly audible.

“…… 3.7 mm, not a standard small diameter. A sexy-sounding woman's voice came from below.

"Not the standard format?" A dull male voice asked. Ah Qi heard that it was Liu Dengji's voice.

"Hmm. It should be developed privately by a laboratory or R&D institution. The female voice responded.

Liu Deng seemed to be silent for a moment before asking, "What are the companies that currently manufacture this kind of bullet?" ”

"It's hard to say. According to publicly available information, a number of companies in Switzerland, Germany and Russia can manufacture it. But in reality, many underground factories have manufacturing capabilities. After a few moments, the female voice let out a "huh", as if she had encountered some perplexing problem.

Ah Qi's heart moved, and he felt that this voice had a sense of déjà vu, but he couldn't remember where he had heard it for a while.

"How could it be...... I've never seen a wound like this......" The woman seemed to have encountered something that was not very sure, and hesitated not to continue.

"Huh?" Liu Dengji seemed a little impatient.

"Judging from the wounds in the Tibetan mastiff's body, it seems that the bullet has exploded twice."

"A secondary explosion?"

"The bullet exploded again after it was fired into the body, and the principle is the same as that of a blasting bullet. Explosive shells are usually fired by artillery or howitzers, and only really explode after entering the target to break through obstacles. The woman paused for a moment, then said, "To be able to produce such a small-caliber explosive projectile, the other party should be very promising." ”

"yes, I see." Liu Dengji interrupted the female voice, and the sound of pacing back and forth sounded in the room.

"Ahem, I think the other side looks like a demonstration." An old voice suddenly sounded, and Ah Qi was taken aback, but he didn't expect that there was someone else in the room.

"How?" Liu Dengji asked the old voice.

"To kill a Tibetan mastiff, you didn't need this kind of blasting bomb in the first place. The other party used this bullet in order to make us retreat. The other party did not hurt anyone's life, and seemed unwilling to form a bond with us. ”

"Hahaha......" Liu Deng laughed three times and said, "Okay, good, good...... What a non-knot! If they take them away, we will destroy them. I only heard a "bang" sound, as if a fist had been smashed on the table. Liu Dengji paused and continued: "How is the situation on Mount Tai's side?" ”

"I have found out that he had taken a rheumatism medication before he was poisoned, called the Pills for Dampness. It is likely that the other party repacked one of the capsules and put some kind of poison into the capsule. The female voice paused and continued: "The poison in Mount Tai is very rare, it is a mixture of a variety of biological toxins, which can act on the human nervous and blood systems at the same time, so that it can maintain a short state of euphoria, and after the hyperactive period, it will die quickly. ”

"Jade Tiger, what do you think?"

The old voice replied, "The other party has made sufficient preparations for this, and strives to hit it with one blow." But judging from the behavior of snatching people tonight, it seems that he hasn't gotten the clues he wants. robbing people shows that they also attach great importance to that reporter. ”

"Hmm...... Black Dragon, be sure to find out the whereabouts of that reporter. ”

A young male voice responded, "Yes." ”

"Also, find out what the people who helped him that night were."

"Yes."

At this time, there was a slight "beep" sound in the room, and a sound similar to that of an electric motor came faintly. After about three or four seconds, the sound of the electric motor stopped, and a series of footsteps sounded, as if someone had walked out of the room. The sound of the electric motor sounded again, and after a moment the surroundings fell silent, and the light coming in through the grille slowly died out.

Ah Qi turned around and waved at Qiu Shan and Liu Qi, signaling them to stay where they were, then took out a small knife from his pocket, screwed out all the screws of the grille box, gently removed the lower frame, and looked down, and saw that although the room was dark, there were a few small indicator lights flashing, and the room was not too big in the faint light, with an oval long table and a few chairs.

Ah Qi took out his flashlight, shone it around the room, and then jumped down from the exhaust port. Only then did I realize that the walls of the room were covered with a thick flannel cloth, and it was arranged like a small conference room, with a pot of orchids on the long table, and nothing else.

Ah Qi walked around the room and found that there was a projection screen on the north wall of the room near the ceiling, which had been put away at this time. Ah Qi secretly thought that it should be a video conference just now. He groped along the wall for a moment, and found a vertical crack in the middle of the south wall, and a small groove at the base of the wall, which turned out to be the door to the room.

Ah Qi didn't dare to stay too long, climbed back into the exhaust port, reinstalled the grille, returned to Qiu Shan and Liu Qi along the same road, and said in a low voice: "It's a conference room, Liu Dengji held a video conference just now." He then gave a general account of what he had heard. Qiu Shan thought that he had become the target of Liu Dengji and another mysterious organization, and a layer of cold sweat couldn't help but break out on his forehead.

The trio crawled back down the exhaust tunnel back into the original wide square passage, and cautiously crawled all the way west. After crawling for about a minute, I suddenly heard a knock in the distance of the passage, followed by another sound, not loud, but very crisp in my ears. Qiu Shan and the others looked at each other, not knowing what was happening in front of them.
