The man who jumped off the building and disappeared was named Wang Jin, and he disappeared from this world in broad daylight, and no one found him. In the face of nature's mysterious phenomena, the police are often helpless to solve crimes. Because they will only reason according to conventional logical thinking, but in the face of supernatural events, conventional reasoning is all invalid, and many unsolved cases are generated in this way.

Although human society has a legal system to ensure its normal operation, there may be a crime happening in some dark corner. In the same way, although there are laws of nature that ensure the proper functioning of the universe, there may also be things that go against the laws of nature in a certain corner. These supernatural events that violate the laws of nature cannot be avoided, just as lawbreakers cannot be completely avoided.

Zhang Xiaoqiang has recovered and returned to school as normal. Hu Kehao told his classmates to care more about him. There is nothing wrong with his body now, but I am afraid that there will be problems with his thoughts. He was also worried that his intelligence would be impaired after he hit the evil spirit, which would affect his academic performance.

Regarding the case of Wang Jin jumping off the building and disappearing, although Hu Kehao is not a policeman and has no responsibility to solve the case, when Wang Jin and his wife quarreled last night, he was a witness at the scene and thought that he could not stay out of the matter. Hu Kehao's curiosity and awe of nature still exists, and he believes that there must be something strange about Wang Jin's disappearance, and the cause of the incident must be investigated.

According to the police, Wang Jin jumped off the building and disappeared at about 1 o'clock in the morning last night. In order to find out the truth of the matter, Hu Kehao used the method of "waiting for the rabbit" to investigate. He planned to stay in front of the demolition building at night to see what was going on. The night was nothing to Hu Kehao, and he didn't feel the slightest fear. The night gave him black eyes, and he wanted to use his black eyes to find out the facts in the night.

At 10 o'clock in the evening, according to the schedule of the U City Polytechnic University, all students should turn off the lights and go to bed. However, there are so many night owls in the school that they don't go to bed until 12 o'clock at night, and some don't go to bed until 2 or 3 o'clock in the morning. A number of students reported to Hu Kehao that the night owls in the dormitory affected their sleep, and Hu Kehao really couldn't do anything about these night owls except for criticizing and persuading education.

That night, Hu Kehao checked downstairs in the student's dormitory, found no abnormality, and was relieved. He caught the last bus and went to the dilapidated demolition building. There is a street in front of the demolition building, and after crossing the street, there is a corner to the abandoned factory area used by Professor Yang Shimo as a laboratory. There were originally two buildings behind the demolition building, which have been demolished and are empty.

Hu Kehao climbed to the sixth floor of the demolition building, which is the sixth floor where Wang Jin lived yesterday. After Wang Jin jumped off the building and disappeared, his wife was frightened and moved out of here. The house was pitch black, and it was even more eerie than yesterday. Hu Kehao opened the door, entered the room, pressed the switch, and there was no electricity. It turned out that the house had long been cut off from water and electricity, and the people who lived in it in violation of the regulations had to find water and light by themselves.

Hu Kehao turned on the flashlight and found a battery light in the room. There were still two buckets of leftover instant noodles on the dilapidated table, and the residual soup inside was not rancid and exuded a faint aroma. The glass in the window was broken with a few holes, and from time to time the night breeze poured into the room, bringing a hint of coolness. The neon lights in the distance break through many obstacles and spread here, making people feel a little bit of life. There's the hustle and bustle of the city's nightlife, and the desolate demolition area here. In the near future, it will also become a modern commercial housing residential area, and if the vacancy rate is too low, it may become a real "ghost building".

Hu Kehao stood by the window where Wang Jin jumped off the building, looking downstairs, feeling dizzy, I don't know how much courage or despair Wang Jin dared to jump down. Fearing to be bewitched by an unknown mysterious power, he smeared his temples with a very irritating wind oil essence. It occurred to him how nice it would be to have some garlic with him—salted, soaked, and raw. However, the irritation of the wind oil essence is already great enough, and ordinary psychedelic magic can't help him.

Hu Kehao picked up a hard object from the house and threw it down from the windowsill, and he heard the crisp sound of the hard object falling to the ground, which showed that the hard object had not disappeared. How can a living person disappear when he jumps? Could it be that the weight of the falling object is not large enough? Hu Kehao wanted to throw a bigger heavy object down, but he was afraid of hitting someone, so he gave up the idea.

Minutes and seconds passed, and it was one o'clock in the morning. Hu Kehao stared intently at the open space behind the demolition building, that is, the open space where Wang Jin jumped off the building and fell. The temperature dropped at night, and a mist slowly rose around the clearing. Hu Kehao often sees fog in the morning, but the process of fogging at night is rare. The gas-liquid-solid three-phase changes of water, resulting in various weather conditions such as rain, fog, frost, hail, etc., all of which are the operation of the laws of nature.

In the night, the fog was getting bigger and bigger, and Hu Kehao couldn't help but shiver. He looked into the distance through the white fog and saw tall buildings in the distance, as beautiful as a mirage. The image of the mirage is getting clearer and clearer, closer and closer to Hu Kehao, and more and more real. Hu Kehao rubbed his eyes, and clearly saw a real building appear out of thin air in front of the demolition building. The two buildings are so close together that if you jump down from the upper floors, you can jump into this building.

Hu Kehao turned on the flashlight to shine through, and the light met the wall, leaving obvious spots of light, and it seemed that the building that suddenly appeared was not a mirage, but a real building. The exterior of this building is similar to the demolition building where he is located, and it is of the same era. Two adjacent buildings, one has been demolished and the other has not been demolished, it is not known for what reason.

Hu Kehao came to the front of the new building and wanted to climb up, but he couldn't find the stairs at the entrance. He walked around the building, and saw a number of heads poking out of the window of a room, waving to him in unison, shouting something loudly. Hu Kehao was about to talk to them, when suddenly the fog cleared and the building was gone.

Hu Kehao looked at the time, and it took a total of fifteen minutes for the building to disappear from the time it appeared. Hu Kehao guessed that this should be the case: when Wang Jin jumped from the window last night, the building appeared. He fell in the shape of a parabola and jumped into the building. Subsequently, the building disappeared, so Wang Jin disappeared.

On the second night, Hu Kehao still came to explore the disappeared "ghost building". As a precaution, he brought a self-defense weapon. He hired a helper, Master Liu, who knew how to exorcise evil spirits, and did not tell anyone else, so as not to cause trouble or harm innocent people. At one o'clock in the morning, the ghost building really appeared again. Hu Kehao came to the window of someone last night, and those people were still shouting from above, but he couldn't hear it at all, probably shouting for help.

There was no entrance to the ghost building, and Hu Kehao had to force himself upstairs. He took out a rope with a hook and claw, hooked the window sill upstairs, and climbed up the rope with Master Liu one by one. They climbed up to the sixth floor and saw a group of people in the room, listless, as if they hadn't eaten in days.

"What's there to eat! Hurry up and get it! We're so hungry! "When the people in the house saw Hu Kehao and Master Liu, they rushed forward to rummage through their pockets to find food.

Master Liu had a handful of peanuts in his bag, and Hu Kehao had two pieces of chocolate on his body, both of which they turned out. The person who got the food was about to feast on it, but someone else snatched it, and the chocolate fell to the ground, trampled to pieces, and no one could eat it. Ignoring nothing, these hungry people picked up the crushed chocolate from the ground and ate it into their stomachs. The peanuts on Master Liu's body were also eaten by them in the shell. Most of this poor food was eaten by the able-bodied, and the others only drooled and sniffed the air at the smell of fried peanuts.

"Why are you so hungry? What's going on? Hu Kehao asked in surprise.

The few people who grabbed the food replenished their energy and had the strength to speak, and said, "We are in captivity!" I've been imprisoned here by a pyramid scheme! People from outside can enter this building, but people in this building can't get out! ”
