Ma Lu insisted on going down, and Zhang Heng couldn't find a suitable reason to refuse.

Because he also knew that if he didn't have his own people to follow the subway company, there was a high probability that he would not let them run around in the tunnel, so Zhang Heng and Fan Meinan glanced at each other and agreed to Ma Lu's request.

So Ma Lu then asked the other two inspectors to continue the search along the tunnel, and he himself took the lead and climbed down the iron ladder.

The trio's shoes creaked against the rusty iron railings, shattering the peace of the underworld below.

When he first saw the abandoned platform, Ma Lu actually felt similar to Cheng Sihan, although he had worked for the subway company for 20 years, and he had heard some sporadic rumors during this time, but this was also the first time he had seen this abandoned subway line.

After landing on the ground, he turned on the flashlight in his hand and looked around carefully.

At first glance, the platform looks similar to the one on the metro line above, but if you look closely, you can see the difference, as it has been renovated and rebuilt several times to meet the growing passenger volume and the needs of modern mobility.

However, this platform is probably due to the sudden suspension of construction, and it has perfectly preserved the appearance of the first construction, and you can see a lot of characteristics of the times.

And when Ma Lu looked at the surrounding buildings, Zhang Heng was also observing the footprints on the ground, because no one had been here for too long, and a lot of dust had accumulated on this platform, for ordinary people, especially people with a certain cleanliness habit, they would probably instinctively feel uncomfortable when they saw this scene, but for Zhang Heng, it was precisely because of the existence of these dusts that he could perfectly record the movements of Cheng Sihan and β.

Zhang Heng could even infer the standing posture and movement speed of the two of them at that time from these footprints, and following the footprints left on these dust, Zhang Heng turned the flashlight to the mouth of the tunnel not far away.

"Did they get there?" Malu also noticed the footprints on the ground.

"Chase and run, yes." Zhang Heng said, "And there are no footprints coming back from here, so they either left on some other platform through this tunnel, or they are still in the tunnel." ”

"Great, let's go get them back." Ma Lu showed a touch of joy when he heard this.

But Zhang Heng was not as relaxed as Ma Lu, but frowned slightly.

"How?" Fan Meinan on the side noticed Zhang Heng's solemn expression.

In her memory, Zhang Heng was very calm most of the time, with almost no expression on his face, no matter how dangerous and bad the environment he was in, he always seemed to be able to find a solution, this was the first time she saw this kind of expression on Zhang Heng's face, "Do you feel that Loki is nearby?" ”

"I don't know," Zhang Heng said, "I just vaguely noticed something in this tunnel, as for Loki or something else, I don't know." ”

Zhang Heng noticed that Ma Lu couldn't wait to walk into the tunnel, so he also said to Fan Meinan, "Let's go, your sister and β have already entered, no matter what is inside, we have to go and meet for a while." ”

Ma Lu is the leader of the inspection team, and no one is more familiar with the subway tunnel than him, so ordinary people may still be a little afraid and hesitant when they see the mouth of the black hole tunnel in front of him, but he only feels extremely cordial, and he raises his legs and steps in without hesitation.

And as he walked, he shouted at the top of his voice, "Is there anyone, I'm here to take you out." ”

As a result, only his echo was responded, and Ma Lu was not too discouraged, after all, it had been almost forty minutes since the two girls jumped off the platform in the surveillance, and if the two of them had walked along this tunnel, it was estimated that they would have walked far away, so he kept calling while striding forward.

Zhang Heng and Fan Meinan followed him about two meters away.

In fact, in this case, it is best if the three of them can act silently, because they don't know what danger lies ahead, and exposing themselves too early is not a good choice.

But just as it was difficult for them to stop Ma Lu from coming down, it was also difficult for Zhang Heng to stop Ma Lu from shouting loudly now, after all, if this was a normal search and rescue operation, Ma Lu's current behavior would be more reasonable, but Zhang Heng and Fan Meinan, who were silent in the back, seemed a little inexperienced.

However, Ma Lu didn't complain about the two, he actually didn't know what the origin of the two was, but the leaders above sent a message to let them participate in this rescue, Ma Lu was initially a little worried that Zhang Heng and Fan Meinan were the kind of people who liked to command blindly, and they were pointing fingers and giving orders everywhere, but fortunately, the two of them were very cooperative all the way, and let him organize and arrange the work, just quietly followed behind, and didn't interject much, and reminded him to notice the locks and footprints on the iron door.

Until now, the rescue work has been carried out quite smoothly, even beyond Ma Lu's expectations, and then as long as the two girls who jumped off the platform are found in this tunnel, the mission can be successfully completed, so Ma Lu doesn't care much about the details of whether Zhang Heng and Fan Meinan have opened their mouths to shout like him.

Fan Meinan showed Zhang Heng his mobile phone, indicating that there was no signal here, but this explained why Fan Meinan later sent a message to Cheng Sihan, but the latter did not respond.

The three of them walked like this for about forty minutes, when Ma Lu suddenly stopped and muttered, "Strange." ”

"What's weird?" Fan Meinan asked.

She is also paying attention to the surroundings along the way, I have to say that this tunnel feels quite gloomy, probably because it has been abandoned for too long, there is no anger at all, and the most amazing thing is that after walking for so long, I didn't even see a mouse, of course, considering that there is no food and water for the rats to live, it can be explained that there is no rat to survive.

But it's not annoying.

At least so far, Fan Meinan hasn't seen anything particularly strange and needs to be paid attention to, but the scenery along the way is a bit monotonous.

"We've come a long way and why, why haven't we seen the next platform yet?" Ma Lu looked puzzled.

He himself is an employee of the subway company, and he patrols the line every day, so of course he knows much more about the distance between the platform and the platform than the average person, the subway was originally built for the convenience of public transportation, except for some special lines similar to the airport line, generally speaking, the station will not be too far apart, but now they have walked for a full forty minutes, and it stands to reason that they should have reached the next platform a long time ago.
