In the corner of the Aviation Academy in the middle of the night, there was a clanging sound of metal grinding, followed by a creaking sound of an old and decaying iron door, and then it was silent again!

"Oops, damn it," Chu Juntao's voice came from the liaison, "Behind the door is an old carport, I can't see it!"

Long before Chu Juntao spoke, Zhou Tang had already seen through the video sent back by the drone that there was a carport behind the towering courtyard wall of the Aviation Academy, and when Chen Zibai entered, he temporarily disappeared!

Zhou Tang has also seen this old carport before, it is located behind the old teaching building of the college, the location is the most remote, and it can almost be called a forgotten corner!

Although there are no details, it is conceivable that the old carport must have been abandoned long ago.

"Peeling," Li Xiaoxian ordered from the contact, "Hurry up and let the drone fly into the courtyard, he may be going to enter the building where Teacher Chen is teaching, right?"

"She ......," Si Rui wondered more and more, "what is he going to do in that building?

"Hehehe......" Kong Wang immediately accosted, "Fate won't joke like this, Brother Tang?

"If we had known this, we would have gone over and searched it earlier, wouldn't it have all been solved?"

"Hey?" As soon as the words fell, Chu Juntao's unexpected voice came from the liaison again, "No, it's been so long, why haven't you seen him come out of the carport?"

"Yes...... Li Xiaoxian also wondered, "Could it be that the carport is also locked, and he is still tinkering with the locks?"

"Steady, steady!" Zhou Tang found that the detectives were too excited, and immediately reminded everyone, "The place is so big, he can't run anywhere!"

"Listen to my orders," Zhou Tang ordered, "Peel the drone up a little bit, stare at the movement inside, and the others and I will slowly approach the iron gate, let's see the situation first!"

"Remember, be careful with me, don't make a noise......"

After receiving the order, the detectives began to act, and Zhou Tang and Li Xiaoxian also carefully climbed over the low wall and entered the deserted alley leading to the iron gate.

They then crept in the direction of the iron door, listening alertly to the movement in the liaison.

1 minute, 2 minutes, 3 minutes...... 5 minutes ......

When 10 minutes passed, the detectives finally couldn't hold their breath, and Chu Juntao said with great certainty: "That's right, I haven't seen him come out of it!"

"What the hell is he doing in the carport?"

Hearing this, Zhou Tang moved forward a few meters and came to the iron gate that had been opened.

However, the door was closed by Chen Zibai, and he couldn't see the situation inside the door at all.

So, Zhou Tang put his ear to the door and listened to the movement inside.

Inside, however, there was a dead silence, and there was no sound.

Wrong......

Finally, Zhou Tang realized that something might be wrong, so he hurriedly signaled to Li Xiaoxian, Li Xiaoxian understood, and immediately took out his matching gun!

Originally, Zhou Tang also had his own gun, but it was not convenient to hold a gun after his arm was injured, so he did not carry a gun in this operation.

Li Xiaoxian also listened to the iron door now, and after finding that there was indeed no sound behind the door, he gently opened the iron door and then got in!

Zhou Tang followed, wanting to see the situation inside, but because the light was too dim, he basically couldn't see anything.

However, with their innate sense, after the two entered, they immediately realized that there might be no one in the carport!

Well?

Unexpectedly, Zhou Tang quickly turned on the flashlight function of his mobile phone and shone it on the carport.

There are a lot of broken tables and chairs piled up in the old carport, and some zombie bicycles that have been turned into scrap metal, and the air smells damp and moldy!

Under the light from the flashlight, you can also see a thick layer of dust swirling and flying in the air......

This......

The carport is not big, almost at a glance, Zhou Tang and Li Xiaoxian are very sure that they didn't see any figures!

What's going on?

What about people?

Li Xiaoxian's eyes showed great doubts, thinking that could it be that Chen Zibai had discovered them a long time ago, and this was a trick for the golden cicada to come out of the shell?

But...... What about people?

Ay?

Finally, Zhou Tang, who began to observe more powerfully, discovered the problem, and he saw that in the depths of the old carport, several tables seemed to have moved their positions, so he hurriedly walked over!

No way!

No way?

When he and Li Xiaoxian came to the back of the table, they couldn't help but be surprised, but they saw that there was a well-well on the ground behind the table!

This well is different from a normal well, the entrance is square, and it is a bit larger than a normal well!

The manhole cover has been opened, revealing the entrance to the black hole......

"Brother Tang, Sister Xian, what's the situation?" At this time, the anxious detectives asked, "Can you speak? Are you safe?"

"Safe ......" Zhou Tang first glanced at Li Xiaoxian, and then lowered his voice and said, "There is a well in ......the carport!

"Huh?" Si Rui said, "You must be careful, Kong Wang and I will go over immediately......"

At this time, Li Xiaoxian squatted in front of the wellhead, and then lowered his head and poked down.

Seeing this, Zhou Tang quickly grabbed Li Xiaoxian's body.

As a result, Li Xiaoxian only looked at it for a few seconds, then drilled out, and then pointed out a direction very carefully!

Oh......

Zhou Tang understood what she meant, it should be, there is a sewer or tunnel below, and there is movement in a certain direction of the tunnel, it should be Chen Zibai below!

Oh......

Suddenly, Zhou Tang let out a low breath, feeling that the hairs on his body stood up!

If...... There's a tunnel down there, so...... Could the mysterious place about Chen Zibai be down there!?

Zhou Tang thought of this, Li Xiaoxian understood it even more, and immediately asked Zhou Tang to turn off the light, and then drilled into it along the vertical ladder next to the edge of the well!

Zhou Tang looked down nervously, although he couldn't see clearly, he soon heard the sound of water, indicating that there was water below......

"Come on......" Through the liaison, Li Xiaoxian said very softly, "Come down, Brother Tang, it's not too deep......!"

Hearing Li Xiaoxian's voice, Zhou Tang hurriedly held the vertical ladder with one hand and drilled down.

The water on the ground was not deep, only ankle-high, but the pungent smell of corruption was unbearable.

After going down, Zhou Tang observed and found that this was definitely not a sewer!

Because there are concrete walls all around, it's obvious that it's a tunnel!

Sneer......

At this moment, there was a sound of some kind of metal grinding from the depths of the tunnel, and bursts of light flashed in the darkness, and it was obvious that Chen Zibai was in the distance......

So, Li Xiaoxian and Zhou Tang walked gently along the tunnel towards the bright light.

The tunnel is not long, they walked more than ten meters, and a fork in the road appeared on the left, and the light came from the fork.

"Brother Tang......" At such a critical moment, Chu Juntao's voice suddenly came from the contact, "I found it!"

"It turns out that there is an air defense project underneath this school building...... As the saying goes, it's a bomb shelter!"
