Returning from the full level: I have covered that sick child

Song Chi and Zheng Lie jumped into the courtyard wall almost at the same time. As soon as he landed, the sound of Zheng Qin sucking instant noodles came from the earphones of the four of them.Zheng Qin said in a vague voice: "The monitoring has been turned off, you go in quickly."

After a pause, Zheng Qin said: "The monitoring of this mental hospital is equipped with a firewall. There is something about this firewall, which is more interesting than I imagined. Before the on-duty staff finds out, hurry up and go in."

"Once they find out that the monitoring is interrupted, and they ask the owner of the firewall to help, I can only try to delay the time for you."

Hearing this, Zheng Lie's expression changed slightly.

It is really rare to see a hacker that even Zheng Qin is afraid of.

"Okay, let's act."

This psychiatric hospital is doing very well, with a wide yard, which looks like a school.Huo Wen'an is quite familiar with this hospital. They are now in the backyard of the hospital. It is a grass park for patients to walk and relax. There is an old rockery in the middle of the grass.

Huo Wen'an stared at the rockery, and stopped hesitantly.

Xu Xingguang looked along the rockery, and guessed that Huo Wen'an thought of Huo Xin because of seeing things and thinking about things. She said softly, "Huo Xin is still alive."

Hearing this, Huo Wen'an instantly regained his sanity. "Go forward, the building on the left is the office building, the canteen is in the middle, and the patient building is on the right."

They are going to an office building.

There was an iron chain hanging on the office building, Song Chi took out the tools he carried with him, and opened the iron lock without any effort.After opening the door, Song Chi habitually turned the lock on the door, creating an illusion that the door was still locked.

Zheng Lie asked him in a low voice: "Aren't you afraid that they will find us and just lock us inside?"

Song Chi said: "I've already discovered it, so there's no need to hide. You can't get out by going directly to the main entrance. The correct way is to find another exit."

Zheng Lie nodded and praised: "As expected of a professional."

Song Chi couldn't tell whether Zheng Lie was praising him or mocking him.

The office building is equipped with sensor lights, which were temporarily locked by Zheng Qin's network control.The whole building was in a state of no electricity and no monitoring. The four people put on small searchlights and started checking from the first floor.

When they went upstairs, both Xu Xingguang and Huo Wen'an uncontrollably thought of the past that Grandpa Xie told.

As they stepped on the stairs to go upstairs, they always felt the sound of blood flowing, as if when they looked up, they would see the dead man's eyes wide open, and they could touch the warm blood with just a touch of hair.

But both of them were people who had rolled in the mountains of corpses and seas of blood. Even though they were a little scared, they didn't feel scared.

The office building has five floors.

Every time she went to a floor and entered a room, Xu Xingguang would ask them to help her measure the length and height of each room.

At first, Zheng Lie and Song Chi didn't understand the purpose of Xu Xingguang's collection of these data. They only looked at Xu Xingguang blankly after they checked the entire office building and found no problems.

Zheng Lie asked her: "Miss Xu, there is nothing unusual."

"Do not talk."

Xu Xingguang suddenly squatted on the ground, took out the pen and paper he carried with him, and began to draw on the paper very quickly.Huo Wenan and the others stood behind Xu Xingguang, watching her movements with lowered eyes.

But in just 5 minutes, Xu Xingguang drew the internal dimensions of the entire building, and accurately marked the precise data of each room.

After reading the picture on the paper, Huo Wenan, who is also proficient in numbers, pointed to the upper right corner of the rightmost room on the picture, and said in a deep voice: "The northeast corner of the room at the end of the corridor is inclined. Between the fifth floor and the first floor, the data value The difference is almost 1.2 meters."

In fact, this building looks like a standard cuboid from the outside, so the total length of each floor should be about the same.

There is a problem here.

Neither Zheng Lie nor Song Chi were idiots, they immediately guessed a possibility: "There is a secret space hidden in the northeast corner of the room at the end of the corridor on the first floor."

"That's right."

Xu Xingguang folded the sheet, and she said, "Let's go to the first floor."

"it is good."

The four quickly came to the first floor and went straight to the room at the end.

This is an equipment room where sundries are piled up. There is no obvious accumulation of dust on the floor, and it seems that it is often cleaned.In the northeast corner are some intact but unused terra-cotta planters and some IV stands.

Zheng Lie and Song Chi took the initiative to move those things away.

Zheng Lie reached out and knocked on the wall, then turned to Xu Xingguang and said, "It's solid."

"It's just an illusion." Xu Xingguang walked to the wall, and she said, "It only needs to apply a layer of special substance on the wall, and the wall can be knocked on, giving off a dull and heavy illusion. Some have Experienced secret path designers know this."

Hearing this, Zheng Lie subconsciously asked, "Then how did Miss Xu know?"

The house was quiet.

Xu Xingguang smiled and said, "I'm that kind of experienced designer."

Zheng Lie blushed and lowered his head, and simply kept silent.

Xu Xingguang took out the tape measure again, and re-measured the wall in front of her. She found an intersection, and then looked back at the wall behind her.She stretched out the tape measure in her hand, and when the tape measure stretched out to 1.2 meters, she said to Huo Wen'an, "Brother Zui, go to the end of the tape measure."

Huo Wen'an walked to the end of the tape measure.

There was an open space, without any protruding things that seemed to be switches.

"Squat down." Xu Xingguang said, "Tap the floor tiles with your hands."

"few times?"

Xu Xingguang frowned and said, "How do I know this? It all depends on the designer's preferences." She asked Huo Wen'an, "What do you think it will be?"

Seeing that Song Chi and Zheng Lie were looking at him teasingly, Huo Wen'an himself felt ashamed.

He chose to close himself, quickly flexed his fingers, and tapped the ground.

One time, two times, three times.
When he hit the tenth time, the wall was still unresponsive.

"Don't knock." Xu Xingguang said, "A voice-activated mechanism lock like this cannot exceed ten digits."

"Then" Huo Wen'an thought for a while, and said uncertainly, "Isn't it as simple as a few taps?"

"En." Xu Xingguang turned around to look around the equipment room, and noticed a painting hanging on the wall behind him.The painting shows a half-open door, and outside the door is a staircase leading to heaven.

Xu Xingguang approached the painting, stared at it and studied it carefully for a while, then suddenly said to Huo Wen'an: "First knock twice, then five times, and then...a slap."

Although Huo Wen'an was confused, he still did as Xu Xingguang said.

The moment he slapped his hands, there was a rumbling sound in the wall in front of Zheng Lie and the others. It was the sound of countless mechanisms turning simultaneously.

After more than ten seconds, a strange creature like corn silk suddenly crawled out of the wall. The thing floated on the wall, gathered into one eye, and stared strangely at the people in the room.

Both Zheng Lie and Song Chi were scared by this thing and took two steps back. Huo Wen'an and Xu Xingguang stepped forward and looked at that eye. Huo Wen'an felt very uncomfortable.

"I felt like throwing up," he said.

Xu Xingguang stared at the thing and said, "Two, one hundred, five."

Hearing that, the thing merged with the wall strangely, and the next second, the east wall suddenly fell down as a whole!
It turned out that the entire wall was the entrance to the secret base.

After the wall fell into the ground, a 1.2-meter-long, 1.2-meter-wide ladder appeared in the northeast corner!
Seeing this, Zheng Lie suddenly looked at Xu Xingguang in awe.

Huo Wen'an said with a dark face, "It turns out that the password to open the door is 250. Who are you scolding?"

Xu Xingguang said: "Generally, the designer who designed this mechanism is either the planner of the whole plan, or someone who is mortal." She looked at the painting behind her and said, "The designer of this mechanism, He has already gone to heaven, and the moment the organ was completed, he locked himself inside the organ."

"That painting is the answer he left for the buyer."

"Two hundred and five, it means cursing. That designer is using his work to mock the planner of this secret base." Thinking that every time he enters this secret room, the other party has to say two hundred and five, isn't it funny?

Hearing this, Huo Wenan and the three of them felt incredible.

"Zheng Lie, Song Chi, you stay here and guard." Xu Xingguang checked the headset and said to Huo Wen'an, "Brother Zui, let's go down."

What's down there, no one knows.

Xu Xingguang didn't want Zheng Lie and the others to see the things below.

Song Chi and Zheng Lie were both hesitant, they knew that this might be the most dangerous place.Rather than staying here, they wanted to accompany Xu Xingguang and Huo Wen'an to go on an adventure.

"Listen." Xu Xingguang told the two of them: "There is a deep conspiracy hidden in this mental hospital. This is the entrance, but there may be other exits. Let you stay here, not because you are useless, but because Because once someone finds us, you two will have to stand outside the entrance and fight with your life to delay us."

"So your role is actually very important, understand?"

Song Chi and Zheng Lie immediately felt a heavy responsibility on their shoulders.

"Don't worry, we will definitely stay here!"

"Ah."

After comforting the two, Xu Xingguang and Huo Wen'an put on gas masks and went deep into the underground world.Walking down the dark stairs, Huo Wen'an smiled and said, "You're pretty good at fooling people."

"No, what I said is true." Xu Xingguang said: "Scheming foxes can't design the exit and entrance at the same place, they will definitely leave a retreat for themselves."

"I said just now that once someone finds out, it's true to ask Song Chi and Zheng Lie to guard the entrance to delay our time." Xu Xingguang said calmly and ruthlessly, "We may be facing something that could threaten the lives of people all over the world." The unknown threat, on the way to find out the truth, will inevitably shed blood."

"Huo Wen'an, I'm not a soft-hearted girl. Are you disappointed by this?"

Huo Wen'an watched her stubborn and calm back, smiled, and said, "What are you afraid of? If there are destined to be casualties on this road, then I will try my best to accompany you to the end and become the gatekeeper on your end."

"Xingguang, you just go forward boldly."

Hearing this, Xu Xingguang's tense back slightly relaxed.

"We've reached the ground." Xu Xingguang's feet had already stepped on the floor.

She raised her head, and the searchlight on her forehead shot into the distance, illuminating the situation in front of them.It was an office with closed doors, and the office was marked with a door number.

Xu Xingguang and Huo Wen'an walked forward at the same pace.

Xu Xingguang looked to the left, and Huo Wenan looked to the right.

Those house numbers said——

Experimental specimen room 1, experimental specimen room 2
All the way to room 40 of the experimental specimen.

In this basement, there are forty rooms specially used to store 'specimen data'.They didn't know what those specimens were collected from, nor did they know the function and purpose of collecting these specimens.

"What's in front?" Huo Wen'an found that there seemed to be a wide open space in front of the office.

"Go and see."

The two came to the open space cautiously, raised their heads, and checked their surroundings with the searchlights overhead.

In front of them stood a carved stone pillar with the inscription—

Secular World Clearance Project.

Below the stone pillar is a long staircase extending downwards, and at the end of the staircase is a square with no end in sight.

On the square, there are countless bulletproof transparent experimental cages, in which there are many "monsters" with strange and twisted postures.

Animals, plants, and humans are kept in cages.

They are all dead.

Someone maintained the posture of wanting to break the glass, and swallowed his last breath.There are animals curled up in the corner of the cage, licking their wounds alone
They were all mummies.

The entire underground of Cangshan Town is an experimental square!
Seeing this scene, Xu Xingguang only felt creepy.

Good morning.
