The security guards at the psychiatric hospital were skeptical of Zhou's speculation and showed a disdainful expression.

The security guard said: "How can the escaped patient dig a tunnel and run outside in a short time with his bare hands, and besides, we don't see any excavated soil here?!" ”

Zhou Xiaolong said to the security guard: "I didn't say that the patient dug it up by himself, could it be that there is an accomplice?" ”

Long Linna frowned and asked, "Xiaolong, you mean, an accomplice dug a tunnel from the outside in order to catch that preserved egg?!! ”

The security guard shook his head and said, "Impossible, Pidan has been locked up in our hospital for eight years, and he hasn't gone out for such a long time, how can he have an accomplice?" ”

Long Linna retorted: "Time is not an issue. ”

The security guard pointed to the courtyard wall behind him and said, "You see, there is a big road behind this hospital, and the road is so wide, if someone dug a tunnel there, it would have been discovered by passers-by a long time ago." ”

Just as Long Linna was arguing with the security guard, without the permission of the security guard, Zhou Xiaolong turned over and crossed over the holly tree, stepping on the lawn with both feet.

The security guard immediately shouted, "Hey, you can't trample on the lawn!! ”

Long Linna glared at the security guard, her eyes were very hot, and the security guard immediately lowered his head and stopped talking.

After Zhou Xiaolong jumped in, he looked down on the ground, as if he was looking for something else, and Long Linna approached the holly tree and looked inside.

The holly tree was waist-high, and it was difficult to jump over it.

"Xiaolong, what are you looking at?!" Long Linna asked.

"Officer Long, I seem to have found ......" Zhou Xiaolong suddenly stopped and looked down at the underside of the holly tree.

"What did you find?!" The security guard immediately came to see it in surprise.

Looking beyond the holly tree, Long Lina and the security guard saw that where the lawn was not completely covered, there was a rectangular blue manhole cover.

It's not surprising that this manhole cover is here, there is a faucet, and the gardener usually waters the lawn and trees, and from here the gardener will connect a long plastic water pipe to splash the water on the lawn.

When Zhou Xiaolong found the cover of the manhole, the security guard smiled disappreciatively.

Long Linna asked the security guard, "Hey, what are you laughing at?!" ”

The security guard said, "Do you think that this well is so deep that it can lead to the sewer outside, and this is where the preserved egg jumped and escaped?" ”

Long Linna asked, "Isn't this possible?" ”

The security guard shook his head, "Not at all, this well is just a decoration, it is only half a meter deep, mainly to hide the faucet, don't believe it, you can open it and see......"

Needless to say, Zhou Xiaolong had already inserted a finger into the small hole of the manhole cover.

Seeing this, the security guard smiled again, generally it takes a professional crowbar to open this lid, and he would never have imagined that Zhou Xiaolong could lift the lid with one finger.

When Zhou Xiaolong lifted the lid and threw it aside, the security guard was a little dumbfounded, but the three of them looked down, and the security guard was right, the well was very shallow, and there was no space underneath, just to cover up a faucet.

Long Linna was a little disappointed, she was about to say something, but Zhou Xiaolong actually jumped down as soon as she jumped over.

Squatting below, Zhou Xiaolong looked at it like this, and he said loudly: "Officer Long, that patient escaped from here......"

"Ah......h

The security guard and Long Linna ran around to the cover of the manhole, and the security guard took out a flashlight and shone it inside, although the bottom of the well was dead, only a large faucet was erected, but a large hole was dug out of the side of the well.

If you don't jump under the well and look down, you just stand on it and look down, you can't find it at all.

Long Linna looked at the security guard very unkindly and asked loudly, "Is this ...... How do you explain that???!!! ”

"Ah...... I...... I don't know???!!! ”

Long Linna stared at the security guard viciously, took out her mobile phone, and said into the phone: "Xiao Li and Xiao Zhang, I found a problem, you should bring a few colleagues to the mental hospital, I am waiting for you here......"

The security guard was a little panicked at this time, he couldn't imagine that someone had really dug the tunnel!!

……

A short time later, colleagues from the police force arrived, and another technician put a remote-controlled robot under the well and drilled through the hole in the side of the well.

The technician had been remotely controlling a handle, and Zhou Xiaolong and Long Linna looked at the monitor.

The little robot has a camera and a flashlight on its body, which can transmit the picture to the monitor, and the little robot has been passing through the entire tunnel, and Zhou Xiaolong and Long Linna have been watching the monitor carefully.

Zhou Xiaolong saw some doorways, and he found that the hole was dug very carefully, and the surrounding area was very smooth, and it must have been dug by professionals.

The little robot walked all the way, seemingly crossing the big road behind it, until it reached the sewer, and if it went down, it might fall.

The technician then controlled the little robot and walked back.

Then, Long Linna sent someone to the other side to investigate, and soon, the colleague who sent there said that there was a manhole cover for the sewer on the ground, and there was an unfinished building around, and the situation was more complicated.

The unfinished building has been here for four or five years, and it is in tatters and surrounded by iron sheets, even if there will be some mounds of soil when digging tunnels, it is not easy for passers-by to find it.

Zhou Xiaolong secretly thought, it seems that the planner really has ulterior motives!!

……

The case has been investigated here, and the way the patient Pidan left the psychiatric hospital has been found out, but how Pidan escaped from the well-guarded No. 7 inpatient building is still an unsolved mystery.

So, Long Linna and Zhou Xiaolong returned to the top floor of the inpatient building for the second time, and checked in the room of the preserved egg for a while, but unfortunately, they still found nothing.

"Xiaolong, can't we do anything?" Long Linna said discouragedly.

"Officer Long, I can't think of it, but I can go back and ask a master ......," Zhou Xiaolong said.

"And the masters?!" Long Linna asked.

"Yes, it's my uncle Bai Zimo!!"

"Ah, you mean, that fat hen that can only talk?!!"

"It's not a hen, it's a parrot, okay?!"

"Yes, yes, it's a parrot, a macaw," Long Lina said with a wry smile, "but, that parrot, will you help me?!" ”

"That's it, I'll go home now, go and ask my uncle, if even my uncle can't do anything, then Officer Long, you can only go and ask for another master......"

"Okay, then I'll have someone send you back now!" Long Linna said.

"No need, you're so busy, I'll just take a taxi back by myself, Officer Long, let's communicate on the phone at any time......" With that, Zhou Xiaolong walked towards the exit of the hospital.
