|||->-> Qingzhu pushed open the glass door, feeling that the glass was very heavy.

Qingzhu asked the security guard, "Is this door usually locked?!"

The security guard said: "This place will only be locked after the caregiver gets off work. ”

Pushing open the door and walking out, Qingzhu saw that behind this was a lawn, there were several big trees, and there were some moon flowers under the big trees.

At the edge of the lawn, a row of holly trees has been planted, which have been trimmed squarely, like a fence.

There's nothing suspicious here.

Although the tree is bigger, there is absolutely no one behind the tree, and all the scenery can be seen at a glance.

After passing the lawn, there is a high fence behind it, and there are many silver wires on the wall, which are probably safety facilities.

Jin Mulan was disappointed and said, "It seems that there is nothing ...... here"

Qingzhu touched his chin and said, "If the image captured by that camera is real, that patient will inevitably pass by here after leaving from behind......"

Jin Mulan said, "Dao Chief, so what?!!

Qingzhu said: "It is impossible to go out over the wall, such a high wall, it is inevitable that you will not touch those wires if you jump over, no matter how good the light work is, it is useless here......"

When the security guard heard Qingzhu actually mention light skills, he suddenly laughed, "Xiaodao chief, have you watched too many martial arts movies, where is anyone still doing light skills now!!"

Qingzhu ignored the security guard's taunt, and he whispered to Jin Mulan: "Jin Jushi, if you want people to escape without knowing it, it is not completely impossible......

Jin Mulan asked nervously, "Dao Chief, what do you mean......"

Qingzhu replied, "If I want to escape from here, I will dig a tunnel underground, so that I don't have to go through the fence and naturally I won't be seen by others......"

Jin Mulan thought about it, and immediately shook her head and said, "Dig a tunnel here?......!" That's a little unrealistic?!!"

The security guard came over, smiled, and said with a disdainful expression: "That preserved egg is bare-handed, how can he dig a tunnel and run outside in a short time, and besides, we haven't seen any excavated soil here?!!"

Qingzhu said to the security guard: "I didn't say that the patient dug it himself, could it be that there is an accomplice?!!

Jin Mulan frowned and asked, "I see, you mean, an accomplice dug a tunnel from the outside in order to meet that preserved ?!!"

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 suddenly have an accomplice!!?

Jin Mulan 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 Jin Mulan was arguing with the security guard, without the permission of the security guard, Qingzhu 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!!"

Jin Mulan glared at the security guard, her eyes were fierce, and the security guard immediately lowered his head and stopped talking.

After Qingzhu jumped in, he looked down on the ground, as if he was looking for something, and Jin Mulan approached the holly tree and looked inside.

The holly tree is waist-high, and it's actually quite difficult to jump over.

"What are you looking at?!" asked Mulan.

"Immeasurable Heavenly Venerable, the poor road seems to have been

Found ......"

Qingzhu suddenly stopped and looked down at the underside of the holly tree.

"What did you find?!" the security guard immediately ran over to see it, surprised.

Looking beyond the holly tree, Golden Mulan 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 Qingzhu found the cover of the well, the security guard smiled disapprovingly.

Jin Mulan asked the security guard, "Hey, what are you laughing at?!"

The security guard said, "Do you think that this well is deep enough to lead to the sewer outside, and that's where the preserved eggs jumped and escaped?"

Jin Mulan asked, "Isn't this possible?!!

The security guard immediately 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, Qingzhu 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 Qingzhu could lift the lid with one finger.

When Qingzhu lifted the lid and threw it aside, the security guard was immediately dumbfounded.

However, the three of them looked down and saw that the security guard was right, the well was shallow, and there was not much space underneath, just to cover up a faucet.

Jin Mulan was a little disappointed, she was about to say something, but Qingzhu actually jumped down as soon as she jumped over.

Squatting below, Qingzhu looked at it like this, and he said loudly: "That's right, the patient escaped from here......"

“…… Ah???!!!h

The security guard and Jin Mulan ran around to the cover of the manhole, and the security guard took out a flashlight and shone 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.

Jin Mulan looked at the security guard very unkindly and asked loudly, "This...... This one...... How do you explain it???!!!"

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

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

Qingzhu squatted below, and he had already seen 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.

What is the structure inside, but Qingzhu can't see clearly.

However, it was not difficult to see inside, Qingzhu summoned the Golden Silkworm Gu and let the Golden Silkworm Gu fly in to explore the reality.

The Golden Silkworm Gu flew all the way, and the green bamboo connected to the eyes of the Golden Silkworm Gu, except for feeling a little dizzy, everything inside could be seen clearly.

This secret passage, far longer than Qingzhu imagined, seemed to cross the large road outside the wall, and then entered another sewer.

The Golden Silkworm Gu flew out of a gap in a manhole cover and looked around.

Qingzhu clearly saw that there was an unfinished building around, which seemed to have been unattended for a long time, dirty and messy, and the situation was very complicated.

The unfinished building has been here for four or five years, and the surrounding area is in tatters, and it is still in use

The iron sheet is fenced, and even if there are some mounds of soil when digging the tunnel, it is not easy for passers-by to find it.

Qingzhu secretly thought: It seems that the planner really has ulterior motives!!

recalled the Golden Silkworm Gu, and Qingzhu told Jin Mulan the simple situation.

Jin Mulan took out her mobile phone and hurriedly asked her colleagues to go to the unfinished building to investigate, but Qingzhu also knew that if she went to investigate now, she would not find anything, after all, the preserved eggs had been running away for several days.

The case has been investigated here, and the way the patient Pidan left the mental hospital has been found out.

However, how the preserved egg escaped from the well-guarded No. 7 inpatient building is still a mystery.

So, Jin Mulan and Qingzhu 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 didn't find anything.

"Dao Chief, can't we do anything???" Jin Mulan said discouragedly.

"Jin Jushi, if this is not the case, you go out first, let Poor Dao stay in this room alone for a while, maybe you can find something?" Qingzhu said euphemistically.

"Dao Chief, do you want to use any spells that people can't see?!!" Jin Mulan asked curiously.

"Uh, sort of!" Qingzhu nodded.

"Alright then, I'll go out right away and guard the door for you!"

Jin Mulan walked out of the ward, closed the door, and saw the male nurse looking inside with a curious face.

Jin Mulan turned to the male nurse and said, "Now we are going to carry out a secret investigation, no matter what happens in the future, you don't ask, remember if there is !!"

The male nurse nodded and said, "Okay, okay." ”

Jin Mulan closed the door vigilantly, and then, with her back pressed against the door, she also blocked the small window on the door with her back.

Now that only Qingzhu himself was left in the house, he released the Golden Silkworm Gu, Mu Mu and Big Radish Ginseng, and asked everyone to help find clues together.

The Golden Silkworm Gu flew around the small room, looking at it very curiously, but unfortunately it didn't find anything suspicious.

The big radish ginseng couldn't fly, so he had to lie on Mu Mu's back and let Mu Mu fly with him.

Although the big radish ginseng is an experienced high-grade spirit grass, in such a small room, he flew around with Mu Mu, and to be honest, he didn't see anything abnormal.

Qingzhu reminded: "Radish, here you are the deepest, you are the smartest, you have to take a closer look, that preserved egg can't be eaten in vain?!!"

", the deity will never eat preserved eggs in the future, okay!!"

The big radish is really sweating, but although this guy's eyes are small, they are much sharper than ordinary people.

The big radish suddenly pointed to a metal wall with a short finger and said to everyone: "Hey, don't you think that the wall in this house is much cleaner and brighter than the wall outside?!!

Qingzhu said, "It can't be because the lights here are brighter, right?"

The big radish ginseng immediately shook his head, urging Qingzhu to get closer to the wall.

Looking at it up close, even Qingzhu felt strange, because the heavy metal wall was covered with many subtle traces of friction, as if it had been polished with fine sandpaper.

"Do you see these traces?" asked the big radish ginseng.

"Well, I saw it, maybe it was left when I was cleaning and wiping the wall???" Qingzhu replied with a frown.
