Zhang Ji coldly shouted in his ears: "Follow me to the rooftop." When I looked back, I saw his figure hidden in the corridor, and this reaction was really fast. On the contrary, Xu Jianglun and the others were stunned and didn't know what was going on, and looked at me, only to come to their senses and chase after Zhang and then left. Gao Cheng tugged at my hand: "Let's go, let's go up and have a look." ”

I silently tried to pump my hand, but he grabbed it and whispered to him, "Let go of it." I didn't want him to be accused like that by the criminal police, but he obediently and domineeringly refused: "What are you afraid of?" I have a clear distinction between public and private, and private is more important than public. ”

A black line appeared on his forehead, but he was helpless to him, so he grabbed his hand and walked onto the rooftop.

Almost instantly, I felt his breath sink and his eyes swept around. At this time, the sky was already bright, about six o'clock in the morning, so the whole rooftop was clear at a glance. On the other end, Zhang Jiling was still checking the traces from the beginning, and when he turned his gaze, he saw that the corners of Gao Cheng's lips curled, and his eyes were shining. Following his line of sight, he found that it was condensed in a dense area of pipes.

It seems that the various pipes of this building are arranged on the rooftop, so that together they have a huge area. If there is a single space in it that is large enough, is it directly underground?

"There's a discovery!" Zhang Ji walked quickly, "There are footprints of suspected suspects at the mouth of the pipeline. ”

Gao Cheng: "So what are you waiting for?" ”

Without much effort, a circular top cover was opened, Xu Jianglun looked inside first, and when he turned around, his face was shocked: "There is an iron ladder that keeps going down." "I stood on the edge of the rooftop and saw that the pipe did not go straight down to the bottom, but connected to the boys' apartment opposite on three floors, and then connected one up and one down to the ground. If this is the secret passage where Director Zhang came up, then the real entrance is actually in the boys' apartment opposite.

Under Zhang Ji's cross-section, he, Xu Jianglun, plus trace inspectors, and Gao Cheng, a total of four people entered to investigate. But when Gao Cheng wanted to let go of my hand, I clung to him, and with a longing gaze, it was impossible for him not to understand my thoughts.

"Take her." Gao Cheng whispered. Just when someone around him was about to speak, his eyes swept over, and they were all silent.

Zhang Ji said in a deep voice: "She is in the middle." ”

So, Zhang Ji and the trace inspector took the lead, I was in the middle, Gao Cheng and Xu Jianglun were behind, and they went down the pipeline ladder one by one. At this moment, I am still worried, and I don't know where the extension leads down? What secrets are buried underneath this academy? Will it ...... Can you find information about your father?

The eyes that looked at Gao Cheng's longing just now revealed this last thought. This is also the root of my coming to this school, when I finally touch, I don't want to be excluded, and I always have to find a breakthrough in the incompleteness of my memory.

The pipes are very wide, enough for one person to pass through, but the further down the air is, the more rotten it is. Listen to the bottom mark inspector reminding: "It's settled." I looked down, and sure enough, the iron ladder was already there. Except for me, each of the four of them has a flashlight, so from the refraction of light and shadow, it can be found that Zhang Ji, who is in the lead, has entered the right path of the bend.

After stepping on the ground, I subconsciously looked at Gao Cheng above, only to see his elegant posture like a leopard silently down, and when he stood in front of him, he glanced at me, and did not mean to speak, and Zhang Ji's cool voice came from behind him: "Let's go down and continue to walk." ”

The parallel stretch of the road was very short, just between the two buildings, and everyone had to bend down because of the height, but soon the front stopped. I heard Zhang Jizai asking: "There are two passages up and down, there is an iron ladder up, and there is only a water pipe downward, how to choose?" Needless to say, he asked the person behind me, and Gao Cheng's voice was close to his ears: "Naturally, there is a way." ”

But Zhang Ji said: "Han Xiao and I are down, and you are up behind." "Han Xiao is the name of the trace examiner. If I hadn't been close to Gao Cheng, I probably wouldn't have heard the laughter in his throat. Seeing Zhang Ji and the trace inspector getting under the pipe one after another, I looked back at Gao Cheng and asked him what to do with my eyes. He only said: "People have their own ambitions and can't stop them." You and I switch places, I'm in front, you're in the middle. ”

Gao Cheng squeezed to the front close to me, and I saw Xu Jianglun, who had been following closely, looking at the probe with a sad face, and whispered when he saw me: "I should be allowed to take the lead in the front, Zhang Ji pressed behind." Before I could make a sound, I heard Gao Cheng in front of me say coldly: "It's not too late to go down and answer now." Xu Jianglun stalked and shook his head seriously: "No, I have the responsibility to protect Xia Zhu." ”

In exchange for Gao Cheng's cold snort, I didn't know what to say. I used to be ignorant and unaware of emotional matters, and I also knew that Xu Jianglun paid attention to me and even sent flowers to be suspected of pursuing, but I didn't go to my heart. After realizing it at this time, I can't say that I don't know anymore, but his honest personality makes it impossible for me to refuse his kindness.

The three of them went up the iron ladder, and no one spoke. My heart is already slightly sunk, I am afraid that this trip will be in vain again, no matter how clever Gao Chengbu's bureau is, it is difficult to prevent the unexpected. When I arrived at the top rooftop, as expected, the extremely obvious shoe prints at the mouth of the pipe were almost the same as the footprints collected before, and it was already certain that Zhang Xiaodong had gone down from here to Li Jiajia, the girls' apartment.

In this way, Zhang Ji's side and the trace inspector went down to the bottom, but there was no result. Xu Jianglun looked sad after he came up, and after staying for a while, he said to go down to find Zhang Jithem, but I didn't stop him. Seeing him go down again, his figure disappearing, he couldn't help sighing, trying to find the passage to the underground, it didn't seem to be as simple as he imagined.

Gao Cheng glanced at me, "Sigh what?" I replied with some discouragement, "I still can't find that way." "It is not easy to lure Director Zhang into the bait, it is already a surprise, and it will only be more difficult to find more in the future.

But seeing him, he raised his eyebrows lightly: "Who said I couldn't find it?" I was stunned and looked at him suspiciously, "Is there another way?" ”

At least, he revealed something that had been covered up with his stupidity. For example, what you see in front of your eyes. ”

I saw his gaze fall on the mouth of the pipe we had just come up, and a sudden flash of inspiration and an epiphany. What school would install such a pipe between two buildings? What is the purpose of its existence? Communication? Does that mean there are key people in both buildings? This is one of them. The second is that since there is a hidden passage in the form of a pipe, will the secret passage leading to the bottom also be in this way? If so, it's easy to look up, just search for school pipes and similar vents.

Wu thought to himself for a while, and a cool breeze blew on the rooftop, and it was cold. I looked up and saw Gao Cheng standing at the mouth of the pipe, staring down with a thoughtful expression. Only then did I remember that Xu Jianglun had been down for a while, why hadn't the three of them come up yet? It stands to reason that the distance below the bottom is not long, and at this time it should have returned to meet us.

I asked Gao Cheng, "Do you want to go down and have a look?" ”

He frowned at me: "If there is a deep pit at the bottom, and three people have sunk, you and I will go down again to fill the pit?" ”

Belch...... I sneered, "Then you can't just leave them alone." His eyebrows sank slightly, and he only said, "Follow me." "When we walked down from the rooftop building, we met one or two students who got up early, and they just glanced at them and didn't pay much attention. It wasn't until I came to the pipe outside the ground floor that I saw Gao Chengjing sweeping around, and finally knocked on the pipe, but there was no response inside.

It is about five or six meters from here to the connection, and if Zhang Ji and the others are stuck in the middle, they should also be able to hear this knocking sound in response. So, they're no longer in this pipeline. Is it really going to the bottom?

I only heard Gao Cheng chuckle: "Interesting! It's really well done. With that, he walked back into the apartment building, and I followed closely behind, thinking that he was going to go up to the roof again, but after entering the corridor, I turned around and walked to an apartment door.

I was wondering if Gao Cheng wanted to knock on the door or something, when he suddenly took out a magnetic card from his pocket, swiped the magnetic stripe on the door, and the door opened with a bang. Shocking, this ...... I subconsciously looked left and right, and there were students walking around not far away, not paying attention to this side. And Gao Cheng had already pushed the door in and pulled me down.

Ben's heart, which was still stunned, turned into surprise after seeing that the room was empty: "How do you know that there are no people living here?" ”

This is a single room, the bed is not covered, there is no sign of occupancy. Ignoring me, Gao Cheng walked over to the front wall, where there was a desk, and he moved it aside and crouched down to examine the floor. After a few seconds, he saw his hand press on it, and then a tile was warped, and then another one, revealing the circular metal plate underneath.

Gao Cheng had a smile on his face, but his eyes were slightly dark when he looked up, and he asked, "Do you want to go down together?" Without hesitation, I nodded, "I want to." He lowered his eyes and replied, "Then follow me." ”

The metal plate is movable, and when you move it to one side, the entrance to the dark shadow is revealed. Gao Cheng was in front, I was behind, and I jumped down about two meters high. After standing firmly, he looked around with a flashlight, and found that there was a pipe opening in the place where his left hand could reach, and it seemed that Zhang Jithey had really entered here. And there is no other cave at the bottom, but a secret passage that is enough for people to pass through exists.

We didn't stop at the entrance for much, we turned inward one after the other, because it was underground, it was inevitable that it was wet, and the paving under our feet seemed to be a stone slab, occasionally slightly slippery. I wondered, where did you get all these stone slabs to build this underground passage? The walls on both sides were muddy, but I don't know how to make them hard as stone.

As the space grew larger, Takashiro pulled me to my side and walked. When there was a V-shaped fork in the front, we stopped, and I asked him, "Which way?" He lowered his eyes a little and pulled me to choose the left side, and I couldn't help but ask, "Why not the right one?" ”

I thought there was something strange in this, but I heard him answer: "It's comfortable to look on the left." "Choked me all at once, and that's ...... It's so casual.

But as I walked a little inside, I immediately realized that he had not chosen the left side at random, and that the reason for the damper ground was that the footprints in the two rows were evident in the same row as we normally would, with sizes between 41 and 43, mostly male.

Intuitively, I thought of Zhang Jithem, but my heart sank slightly, and the footprints were clearly visible There were only two people, Xu Jianglun must have taken the right side of the road when he found it later, and he didn't have an accident alone. <
