The Fifth Investigation Team sent a request for assistance to the National Security Bureau headquarters email address. After waiting for a night, reinforcements sent by Lin City arrived at the Nanhang Public Security Bureau.

The reinforcements were from the third team among the ten teams for supernatural incident investigation and handling. The team leaders knew each other and had read the case summary sent by the headquarters. The first thing they did when they arrived was to bring the company leader of the fifth team and the only team member into the conference room and ask them about the cause and process of the case.

Shi Yu did not stay to participate in their work, and the Municipal Bureau did not detain him anymore, so he asked for leave from the foreman in advance and returned to Tianshui Lanwan in the early morning.

The decoration team downstairs did not have the habit of being night owls, and the apartment was silent in the early morning.

Shi Yu returned to the room, turned off his low-battery cell phone, locked the door and began to catch up on his sleep.

At eight o'clock in the morning, the humming sound of the decoration team's equipment sounded again on time.

Wen Hesi was carrying a kettle of boiling water and pouring it into the thermos. When he looked up, he saw him walking out of the room: "You didn't go to work today?"

Shi Yu hummed softly and curled up on the sofa.

Wen Hesi looked at him, who was so sleepy that he couldn't even open his eyes. He also listened to the renovation noise downstairs and guessed what had happened without asking. Unfortunately, sleep was not his area of expertise, so even if he wanted to meddle in this matter, he couldn't do anything about it: "Are you really not going to treat your insomnia?"

Shi Yu did not answer, her eyes were half closed, her long eyelashes casting a shadow.

Wen Hesi knew that he had insomnia, since he was hired as a chef seven years ago. How he knew this is not explained here for the time being, anyway, in the six months when he was busy with the case entrusted by the other party, nine out of ten times they met, the other party was in the state of just waking up.

Of course, it was not just insomnia. Shi Yu's lifestyle at that time was extremely unhealthy. Not only was her daily routine reversed, but her housework skills were basically zero and her common sense was almost non-existent. She even had to look up the instruction manual before lighting a fire in the kitchen.

Wen Hesi had been independent since childhood. It was the first time he saw a rich kid who had never even touched a kitchen knife. He was shocked by the backward arrogance and debauchery of the capitalists. Fortunately, he remembered that the other party was the one who paid him, so he did not rise up on the spot.

Although he was shocked, Wen Hesi did not give any instructions. After all, they were only superiors and subordinates. It was not only over the line to control each other's living habits, but also very idle. Only occasionally, when he was not satisfied with it - for example, when he found Shi Yu in the balcony hanging chair after the car accident last month, he could not help but make some sarcastic remarks.

He had always felt that if the other person continued living in this state, he would probably die suddenly at home one day. So after seeing with his own eyes that the other person was still alive and well, he felt that God might really be blind.

The alarm clock just rang.

Wen Hesi returned to the kitchen, took out the omelette from the pot and placed it on the coffee table: "Since you can't sleep, let's eat first."

Shi Yu took the spoon and poked open the egg bag.

Wen Hesi packed the second portion in a lunch box and glanced at him as he was about to leave: "Why haven't I seen you wear that hairpin for a long time?"

Shi Yu hummed: "It's been borrowed."

Wen Hesi was just asking casually. Although he was puzzled for half a second as to who could borrow the hairpin from this person, he did not ask any more questions and went out to serve as a delivery man for the college entrance examination candidate at home.

At nine o'clock in the morning, outside the north gate of the community.

Members of the third and fifth investigation teams were waiting in front of the gate. Some of them leaned over to look at the tightly closed iron gate and the huge iron lock on the gate, and whispered, "This is strange. Why does this community seem to be closed today?"

"What are you thinking? Have you ever seen a neighborhood under lockdown? When we first came here, we passed the south gate exit, and it was still open. It's obvious that only this gate is closed."

"So what's going on here? The key is lost? The door lock is broken? The camera is gone and can't monitor, so just drive everyone else to a place where the surveillance cameras can't see?"

"Maybe God knew that our mission to seal the 'Skylight' today had to be kept secret, so he sealed this road for us in advance to prevent ordinary people from passing by and seeing it."

"...Although, don't be so self-indulgent."

The two team leaders at the other end stood in the front.

A member of the technical team took a machine that was similar in shape and size to a vacuum cleaner and turned it in the direction of the "skylight". He looked down at the measurement results of the machine and looked at the values on it over and over again.

"Team Leader..."

The third team leader came over and asked: "What's the result?"

The technician pointed to the LCD panel.

The resulting map uses contour lines, and the shape it presents can probably be called polarization.

Level 1 includes where they are standing now, mainly distributed outside the contour lines. Because the air flow temperature is uneven, and high-tech products are overly sensitive to temperature, the contour lines in this part are drawn very chaotically, a bit like the surface of water blown by the wind, but the general temperature difference is maintained at an extremely low threshold.

The second level is right in the middle of the contour line, and the surrounding shape is irregular, a bit like a hole in a piece of paper. According to the scale, the longest distance between the two points is about five or six meters, and the edge is just three or four steps above the stairs.

As for the temperature in this area...

The third team leader looked at the area in the center that was painted red by the machine: "So what is the temperature under the 'skylight'?"

The technician hesitated: "1535°C."

The third team leader was stunned: "Are you kidding me?"

The technician shook his head.

The third team leader stopped and said, "If the temperature was really that high, the person inside would have turned into ash the second they entered. How could they have left their bodies intact?"

"Didn't I say before that its power is increasing?" Lian Gui frowned, "and its coverage area has been expanding. I climbed the stairs yesterday, but nothing happened. Today, I tested it and it expanded outside the stairs."

No one spoke.

Finally, the technician broke the silence: "Actually..."

Both of them turned their gazes at the same time.

The technician raised the brim of his hat. "In fact, when the thermometer was first developed, it used the standard temperature of melting iron as the measurement threshold. In other words, although the thermometer measured the temperature under the 'skylight' as high as 1535°C, there is no way to confirm whether this is because the temperature is only 1535°C or because the thermometer can only measure 1535°C."

He paused, and then continued, "Also, although I trust the machine's judgment, even if the temperature under the 'skylight' is measured to be that high, the steps and green belts within its range do not seem to have any problems at all."

It was neither burned to ashes nor melted.

In fact, if you think about it carefully, whether it was the victims in the Tianshui Lanwan community before, or the police officers whose faces were disfigured later, their clothes were not torn at all.

It was as if the strange high temperature only affected humans.

The technician stood up, took out gloves from his backpack, walked to the bush, rummaged through it, and picked a leaf.

He took out a metal rod of unknown name from his bag, clamped the blade on one end, held the other end himself, and pressed a button.

The metal rod suddenly stretched out, and the end holding the blade extended into the range of the "skylight", and then retracted after a moment.

The technician turned the metal pole: "Look."

There is a seven-spotted ladybug lying on the leaf.

Safe and sound.

The technician placed the leaf back on the bush. "We could try other plants and animals, but I don't think the results would be much different."

Ten o'clock in the morning.

The investigation team set up a connected shed several dozen meters long outside the north gate of Tianshui Lanwan. The silver-white metal support propped up the semicircular roof to a height of three meters.

Eleven o'clock in the morning.

The investigation team used a mechanical tower crane to spray polyester foam on the upper surface of the connected greenhouse and spread out insulating resin wool. The exterior of the metal greenhouse was decorated in restrained and inconspicuous tones.

11:30am.

There was a dispute within the investigation team.

"Is there no other way?"

"It may be possible, but I haven't thought of it yet." The technician said, "Whether the skylight corridor is effective or not can only be tested by people themselves."

Lian Gui raised his voice: "Then you should know what the consequences will be if you fail and go in!"

The technician nodded: "But at present, the harm of the 'Skylight' is only to humans. Other animals and plants will not be harmed if they enter the range of the 'Skylight'. The result has no reference value."

Lian Gui: "Then tell me who deserves to go in and take these risks? Who deserves to go through the gates of hell to verify the function of the shed?"

The technician said: "Team Leader Five, I am only responsible for technology, and other issues are not within my scope of consideration."

Lian Gui: “You!”

"Okay." The third team leader interrupted the two, "It's indeed not appropriate to let real people go up to test it directly. Let's think about it..."

"Boss." Someone suddenly spoke up, "I'll go."

Lian Gui turned his head suddenly when he heard the voice.

He was the only remaining member of his team.

The team member named Feng Qu looked at his boss. Because he cried a lot last night, the swelling on his eyes had not yet subsided, and there were still red spots on his cheeks. His voice was hoarse and changed: "I'm not afraid, I can try."

Lian Gui said nothing.

Feng Qu continued, "Boss, I want to solve the problem of the skylight as soon as possible, at least so that Dalang, Xiaowu and the others can..."

Lian Gui grabbed his arm and twisted it.

Feng Qu screamed in pain and almost fell to his knees. The next second, he heard his boss's voice: "You want to go? Why do you want to go?"

"Because you're reckless? Because you're brainless? Or because you have developed tear glands and can produce water to put out fires at your own expense?" Lian Gui sneered, "I'm telling you, you're the only one left in the group now. Even if you lose your guts, you have to live for the 19 people who died yesterday when I took your place on the mission! Who gave you the right to tell me you're not afraid of death?!"

Feng Qu suddenly froze in place, shivering with cold.

The phone rang at this moment.

Lian Gui gave up and answered the phone irritably: "Hello?"

The other end said, "Officer Lian."

It was a call from the Central Hospital.

The hospital didn't know about the existence of their paranormal investigation team, nor did they know which department they belonged to, so they simply called them police officers. He said: "The patients who were brought in early this morning have resumed breathing."

Lian Gui was now concentrating most of his attention on this ignorant subordinate. He pondered for a long time, and finally seemed to understand the meaning of the other party's words. He tightened his grip little by little: "...What did you say?"

"Those eighteen patients have resumed breathing," the doctor repeated.

Lian Gui's mind went blank for a while after hearing this, and he finally found his voice: "They... are still alive?"

"I'm sorry, except Wu Xiao." The doctor was standing outside the ward making the call, explaining in as simple terms as possible: "Although we were also surprised by this, when those 18 patients were sent in, their breathing and body movements were indeed undetectable. It was not until later that we took out the ECG monitor to measure, and found that their heartbeats were actually always there, but extremely weak. And the black charcoal on their body surface, we used some methods to peel it off, and the patients' breathing immediately recovered. How should I put it, I think those patients were actually in a state similar to shock when they were sent in? Suspended death? Hibernation?"

Lian Gui swallowed dryly and tasted blood in his mouth.

The doctor said, "But because the charcoal on their body surface is formed due to severe burns and dehydration under high temperature, and the charcoal is connected to the skin, so we dare not peel it off casually. Even if the top layer is peeled off, it is equivalent to their epithelial tissue being gone, and the cells and muscles are without a protective layer. We can only perform skin grafting surgery on them immediately..."

Lian Gui listened motionlessly the entire time, until even Feng Qu, who was kneeling on the ground, noticed his abnormality and asked with a worried look, "Boss, what's wrong with you..."

The word "了" at the end has not been said yet.

Lian Gui came back to his senses, looked at him, and pressed the speaker button.

"Logically speaking, people with burns like that should have died long ago, but those 18 patients are still alive..."

Feng Qu was stunned as if he was struck by lightning.

Lian Gui waited for the doctor to finish explaining before he said, "Anyway, thank you all for your efforts to save us. The organization will never forget your contributions."

The doctor smiled and said, "I accept their thanks, but I dare not take credit for it. I would rather thank God for showing some leniency. Their skin was burnt to charcoal but they were not killed. That's why we had a chance to save them. This incident can be regarded as a medical miracle."

Lian Gui said nothing.

If God is truly merciful, how could he possibly tear open this "skylight"?

Hang up the phone.

Feng Qu looked up blankly: "Boss, did he just say..."

Lian Gui: "The brothers are all alive."

...Except for Xiao Wu, who initially notified him using the intercom.

Feng Qu stood there in a daze for a long while, and in the blink of an eye, tears rolled down.
