With the progress of the investigation of the case, the hotel plumber and security room have ruled out suspicion, so Yang Yibing, the last assistant to the general manager of the hotel who has not yet investigated, has naturally become the key suspect of the police.

What made the police even more excited was that after Xu Mei's body was found in the water tank, Yang Yibing, who was originally on a business trip, could not be contacted, and his mobile phone was always turned off.

The criminal police who went to Yang Yibing's business trip to investigate brought back more exciting news, that is, Yang Yibing did not go on a business trip at all, but mysteriously evaporated from the world.

According to police analysis, if Yang Yibing committed the crime, then many mysteries can be solved.

The police made a series of bold speculations, and Yang Yibing decided to kill Xu Mei because of an unknown secret.

When he was at the elevator on the thirteenth floor of the hotel, he happened to meet Xu Mei, who had just walked out of the elevator on the thirteenth floor and was entrusted by Zhao Wan'er to come to Shi Liya's room.

When Xu Mei just got out of the elevator and happened to meet Yang Yibing, Xu Mei tried her best to avoid Yang Yibing, and hurriedly returned to the elevator.

She hoped that Yang Yibing didn't see her, so Xu Mei hid in the corner of the elevator.

But how did she know that Yang Yibing had already discovered her, and Yang Yibing, who was familiar with everything in the hotel, naturally knew that this old-fashioned hotel, except for the surveillance cameras in the hotel lobby and elevator, there were no cameras in other places.

Yang Yibing saw Xu Mei and saw that he deliberately avoided it, and his heart was even more murderous, he stepped forward quickly, hid in the place where the elevator monitoring could not be seen, and pressed the switch of the elevator with one hand.

Yang Yibing quietly took out a piece of chewing gum, put it in his mouth and chewed it a few times, and pressed it on the elevator switch.

The elevator switch light stuck by the chewing gum kept on, and the elevator door could not be closed, which made Xu Mei, who was hiding in the elevator, feel a sense of fear after meeting Yang Yibing.

She looked at the elevator that had never been able to close the door, and felt very strange because she was afraid.

Xu Mei listened intently for a while, and saw that there was no movement outside the elevator door, she estimated that Yang Yibing did not see her, and had already left.

Xu Mei was bold, leaned out half of her body, and looked out of the elevator door,

Outside the elevator door, Yang Yibing was gone, Xu Mei breathed a sigh of relief, she returned to the elevator,

Xu Mei, who had just settled down, suddenly looked at the elevator door that had not been closed, and suddenly felt frightened, she hurriedly pressed all the keys in the elevator, although except for the thirteenth floor where she was located, the other indicators were all lit up, but the elevator door still did not move.

Xu Mei was scared in her heart, 'There are ghosts in the elevator', this terrible thought suddenly came to her heart,

So, Xu Mei in the elevator began to make the strange gesture that seemed to be praying for the blessing of the gods and Buddhas seen in the surveillance video.

There were a few footsteps in the corridor, Xu Mei leaned out half of her body and looked at her right hand, but there was still nothing, at this time, Xu Mei, because of the influence of nervousness, she ignored the slightly dark corridor on her left hand side leading to the emergency passage staircase,

Xu Mei, who was extremely nervous, had only one thought at this time, to quickly escape from the hotel.

She was desperate to escape by trying to take the elevator, so Xu Mei decided to walk down the stairs.

may be because Xu Mei believes in the existence of ghosts and gods, so when she just stepped out of the elevator, she didn't forget to make some strange movements towards the right side of the elevator, in order to pray for the ghosts and gods to let her go.

How did she know that at this time, Yang Yibing had quietly walked behind her from the dark turn of the stairs, and covered Xu Mei's mouth with a towel soaked with **,

Under the effect of the drug, Xu Mei immediately fell down softly, Yang Yibing reached out to hug Xu Mei, and walked towards the staircase of the emergency passage,

In the elevator surveillance video, at the moment when Xu Mei's figure disappeared, the hand that was regarded as a 'ghost hand' by many supernatural enthusiasts was inadvertently left by Yang Yibing who reached out to hug Xu Mei, who was about to fall to the ground.

Yang Yibing hugged the unconscious Xu Mei and quietly climbed up the fifteenth floor of the hotel administration from the stairs of the emergency passage.

He took Xu Mei into his office and locked the door.

looked at Xu Mei, who was unconscious, and Yang Yibing, who had moved to kill, carefully calculated how to kill Xu Mei without making people doubt themselves.

He thought of a way to create a bizarre death, and in the case that the criminal police could not detect it, the strange disappearance of Xu Mei was due to the illusion of a supernatural event.

Yang Yibing decided to drown Xu Mei, who was already unconscious, so that Xu Mei could be solved without any external injuries.

He used the washbasin in his office, filled it with water, and then pressed the unconscious Xu Mei's head into the basin.

Xu Mei, who was in a coma, woke up after choking on a mouthful of water because her mouth and nose were pressed into the water.

However, Xu Mei, who had just woken up from the ** state, was weak and had no power to resist, and after a while, she was drowned in the basin filled with water.

Yang Yibing hid Xu Mei's body in the cabinet in his office, packed everything, lit a cigarette, and thought carefully about whether there were any flaws in all his actions.

He had decided to quietly move Xu Mei's body to the huge water tank on the rooftop on the eighteenth floor in the middle of the night, but Yang Yibing suddenly remembered something, and couldn't help but break out in a cold sweat for his negligence.

Yang Yibing, who is the assistant to the general manager, suddenly thought that three days later, the hotel would conduct routine safety testing of water quality.

If Xu Mei's body is put in at this time, then if there is a problem with the water sample tested, a plumber will immediately come up to check the water tank, and at that time, Xu Mei's body will be found immediately.

Yang Yibing settled down, he thought twice, taking advantage of the fact that the weather was not too hot during the Qingming Festival, and the corpse should not emit a foul smell if it was placed for three days, so Yang Yibing decided to wait for the water quality to be routinely inspected for safety three days later, and then hide the body in the water tank.

What he didn't expect was that this step of helpless chess actually helped him a lot, the police searched the rooftop with a police dog at that time, and did not find anything valuable, which made more supernatural lovers insist that Xu Mei's bizarre disappearance was done by ghosts and gods and provided a strong basis, which is equivalent to doing Yang Yibing a big favor,

Despite this, Yang Yibing, who decided to hide the body for three days, still cautiously and repeatedly examined whether there were loopholes in everything he had done.

Yang Yibing concluded that it was impossible for the police to easily characterize a disappearance case as a homicide case, so the intensity of the investigation of the hotel would not be very large.

And as a senior manager of the hotel, his office will never be the focus of the police search.

If the search of the police dog can be disrupted, then it is impossible for the police to conduct a thorough search of his office and find Xu Mei's body.

Yang Yibing thought of a way, he secretly took a bottle of white pepper from the hotel's catering department, and then sprinkled a thin layer in his room and on the way to carry Xu Mei.

As a senior management of the hotel, Yang Yibing is naturally aware of the loopholes in the hotel management, and many guests will litter in the corridor at will.

Therefore, Yang Yibing deliberately took a few packets of instant noodles and sprinkled them in the corridor on the thirteenth floor while no one was paying attention, destroying the sense of smell of the police dog, so as not to attract the attention of the police when the police dog searched for the fifteenth floor.
