Fan Meinan hesitated, but still reached out and knocked on the door of the monitoring room.

"What's the matter?" An unfamiliar male voice sounded in the room, which surprised Fan Meinan, she thought that Zhang Heng had already solved all the people inside, but she didn't expect that the employee in charge of the surveillance video was still there, Fan Meinan almost thought that Zhang Heng was not inside.

But soon she heard Zhang Heng's voice coming, "It's okay, it's my friend." ”

After waiting for about five seconds, the door in front of Fan Meinan was opened, and a staff member with glasses who looked a little chubby came out of it and greeted Fan Meinan warmly, "Come in." ”

"Ahh Fan Meinan was stunned and walked in.

As a result, he saw Zhang Heng looking up at the video above in front of the monitoring platform, he saw β jump off the platform on the screen, and then Cheng Sihan hesitated, took out his mobile phone and quickly entered a few words, and then jumped down together.

The staff with glasses was also stunned when they saw this scene, this ...... After a long time, he suddenly woke up, and hurriedly grabbed the phone on the side, wanting to notify others, but soon his hand was pressed down by Zhang Heng.

The bespectacled staff was stunned.

"We'll take care of that." Zhang Heng said, "We are here to deal with this matter, rest assured, I promise that you will not be held responsible." ”

However, the staff who wore glasses obviously couldn't put their minds at ease, after all, if something really happened, he would definitely be severely punished for concealing the report.

Zhang Heng then added, "This was twenty-five minutes ago, if anything really happened, it would have happened a long time ago, have there been any accidents on the subway that have passed by recently?" ”

"I remember when you say that, a driver has reported that he seems to have seen someone on the railroad track next door, but after a few passing cars, he said he didn't see it, so everyone thought that the driver was dazzled by it." The bespectacled worker said.

However, he soon added, "But this matter cannot be left alone, otherwise it will be too late for someone to die." ”

"I know, I'll fix it." Zhang Heng said, "Anyway, if I don't come to check and monitor, you won't notice this, so as long as I don't come." ”

"This ......" the bespectacled staff looked embarrassed.

After a while, he spoke again, "You are the person introduced by Director Han, of course we are willing to cooperate with Director Han's work, but we also have our rules and regulations here, and you make it difficult for me to do this." ”

Zhang Heng didn't force the staff with glasses, but just asked, "Then how do you deal with it in general?" ”

"This matter must be reported to the leader, waiting for the leader's instructions, and under normal circumstances, the subway on this line must be stopped." Said the staff with glasses.

"Well, then do as you say." Zhang Heng said, and at the same time let go of his hand.

Then he didn't stay in the monitoring room anymore, and walked out with Fan Meinan on the side. After closing the door, Fan Meinan was finally able to ask the question that had been held back for a long time.

"How did you convince him to let you watch the footage? And who is that Director Han? ”

"I got a friend to help me and got in touch with the police station in this area." Zhang Hengdao.

He was looking for someone through Han Lu's connections, but obviously he didn't expect Cheng Sihan and β to jump off the platform, and according to the words of the staff with glasses, the two should have found some way to leave the tunnel later, otherwise there would be no driver to see them.

"We need to take a look in that tunnel." Zhang Heng said, "I'll make another call, even if we can't go down alone, at least we can go with us when the people from the subway company stop the line for inspection." ”

Zhang Heng didn't know how Han Lu did it, ten minutes later, the subway of this line really stopped running, and then the subway company also transferred the inspection team that was most familiar with the tunnel, their usual work generally started late at night, and after the last subway also arrived at the end of the line, it was their turn to appear, pushing the block carrying the starting machine, maintenance tools and materials to patrol the track along the track, and check the screws along the way.

The leader of the inspection team, a northwestern man named Ma Lu, found Zhang Heng and Fan Meinan, who was in his early forties, didn't talk much, but the person looked calm, and asked, "Do you want to go together?" ”

"That's right." Zhang Heng nodded.

"Well, then follow me." Ma Lu didn't talk nonsense, said directly, and then handed Zhang Heng and Fan Meinan a flashlight.

Zhang Heng carried the large travel bag and followed the people of the inspection team down to the tunnel, in addition to the road, there were two other young men, of course, the entire subway inspection team was not the only one, but because of the night shift, most of the others were still sleeping at home at this time.

But anyway, it's only one stop from this platform to the next, and they're enough.

There was no need for the road to command, the two guys had already scattered along the track to check, but they didn't find any problems for the time being, and soon several people came to the iron gate.

A young man in front of him shone a flashlight, and it quickly flashed by.

But at this time, Zhang Heng spoke, "Wait." ”

"What's wrong?" Malu stopped.

"Is the lock on this one usually open?" Zhang Heng asked Ma Lu.

The latter moved the flashlight to Tiemen Mountain, stunned, "Here, the words here have been locked since I came here to work." ”

"Really?" Zhang Heng glanced at the dust on it, it had indeed accumulated for a long time, but not long ago, there were traces of it being opened, and fingerprints were left on it, if nothing else, it was Cheng Sihan and β who opened this iron door, so Zhang Heng continued to ask, "What is the place down here?" ”

The two younger inspectors, you look at me and I look at you, both of them are at a loss, but Ma Lu knows a little bit because he has been in the company for the longest time, and said, "I haven't actually gone down, but I heard some old employees say that there is a subway line down here." ”

"Subway lines? I've used to take the subway a lot, but I've never heard of it, and it doesn't seem to be on the map. Fan Meinan said.

"Because the subway line was abandoned before it was actually built, it is said that the construction plan was changed from above." Ma Ludao, he also reacted at this time, and looked at Zhang Heng, "Do you think they ran down here?" ”

"At the moment, it's very likely." Zhang Heng said, "But I don't recommend that you go down, you can continue to check other places along this road, and let's search for it, so that you can resume operations as soon as possible." ”

However, Ma Lu was obviously a very responsible person, and he said without any hesitation, "I'd better go down with you." ”
