The heavy rain stopped after a while, and the rain swept through the eaves and fell to the ground making a dripping sound, Bai Hao and Xia Ying returned to the dormitory after dinner, they were all waiting for time.

The iron door on the roof of the classroom office building was slowly opened, and the old metal friction made a screeching sound in the night, Fei Kai breathed in the air after the rain, and walked to the edge of the guardrail on the top of the building, he leaned on the guardrail with his hands and looked at the campus in the night.

"What secrets are hidden in the blank diary?" Fei Kai muttered to himself.

At this time, a malicious intent from the old campus behind the school alarmed the spirit detector invented by Feikai.

Pale blue light converged into a beam of light that flew out of the spirit detector towards the old campus on the hill behind the dormitory.

The spirit detector is one of Fei Kai's three major inventions, it is said that there is only one spirit detector in F City, its appearance is very ordinary, like a disc, the main purpose is to detect the movement of the spirit, aimed at some spirits with some strong resentment, as long as the ghost's resentment is strong enough, the spirit detector will radiate a light blue beam in the direction of the resentment, and form a mark on the spirit, the marking time is an hour.

Fei Kai drove in the direction of the old campus, his face was extremely ugly: "Time is running out, if you can't put away those things......"

At midnight, the mysterious bell rang again.

The lights in all the dormitories in the dormitory building are turned off, and the darker it is, the more people feel the fear in their hearts.

Bedroom 640,

In the dark, I only heard Li Erfat's trembling voice: "Lao Bai, it's zero o'clock now." ”

Bai Hao used the light from his mobile phone to shine around, and after a while, he found the table where the computer was placed.

He thought to himself, the ghost letter must be hidden in a drawer.

Zhang Kun, Li Gan and Li Erfat, the three of them all wrapped their bodies tightly with quilts, revealing only a gap, through which they could see Bai Hao's every move.

Bai Hao opened the drawer, and sure enough, there was a letter in the center of the drawer, and three numbers were written in a red pen on the white envelope.

“444”

Bai Hao read out the three numbers on the envelope, then tore open the envelope and took out the letter inside.

The words on the letter paper were still written with a red pen, and from the red handwriting, Bai Hao smelled an extremely obvious smell of blood.

The smell of blood is getting stronger and stronger, even Li Erfat, Zhang Kun and Li Gan can smell this thick smell of blood through the quilt.

At this moment, the situation in the 640 bedroom is the same, Xia Ying also opened the drawer of the table in the bedroom when midnight came, and tore open the envelope and took out the letter inside, but unlike Bai Hao, the letter Xia Ying got did not have a number written with a red pen on the envelope.

The strong fishy smell spread, and the same thing happened in both bedrooms, and everyone felt like vomiting.

640 bedrooms.

Li Erpang forcibly endured the feeling of vomiting: "Lao Bai, have you finished reading?" It stinks, so I'll burn the letter after reading it."

"Yes, Lao Bai, I can't help it!" Zhang Kun's stomach churned.

Li Gan was in a very bad state at this time, he couldn't stand the smell of the fish and vomited incessantly.

Bai Hao carefully memorized the words in the letter in his heart, and then took out a lighter from his pocket and burned the letter.

The flames gradually burned the letter paper, and finally turned the letter to ashes, and at this point, the smell of blood in the dormitory gradually dissipated.

639 bedrooms.

Xia Ying endured the fishy smell and burned the letter paper and envelope together, and the fishy smell in the bedroom dissipated a lot.

Xia Ying couldn't hold back any longer, although the smell of the fishy smell had been reduced by half, she only felt her stomach churning, and her throat seemed to be broken by something, so she quickly ran into the toilet and began to vomit.

Qiushuang, Mizuki and Yang Shanshan will not be much better, listening to the sound of Qiushuang vomiting, they also felt that they were about to be unable to bear it, and rushed into the toilet together and vomited with Qiushuang, and suddenly there were bursts of vomiting in the 639 dormitory.

Because of the relationship between the wall, the boys in the 640 dormitory heard it very clearly, and they were also drawn by the vomiting sound of the girls' door, and the vomiting feeling that they could not hold back anymore and began to vomit.

Bai Hao was the first to slow down, he thought back to the content in his heart just now, and at this time he realized that he couldn't remember the content of the letter, Xia Ying also had the same problem, obviously he had written down the content in his heart, but now he couldn't remember anything.

639The sound of vomiting in the dormitory gradually disappeared, Xia Ying told the sisters in the bedroom that she had forgotten the content of the letter, probably due to physical exhaustion, Mizuki, Qiushuang and Yang Shanshan all said that they would discuss the issue of the letter after a good rest, and they fell asleep after a while, Xia Ying couldn't take care of it so much when she saw this, and her physical exhaustion made her have to go to sleep first.

In the 640 dormitory in the dark, Li Erfat's weak voice said, "Lao Bai, what did you say in the letter?" ”

At this moment, Bai Hao was thinking back to the scene just now, but no matter how he thought about it, he couldn't remember what he had just thought.

"Old white?" Li Erpang saw that Bai Hao didn't answer and asked again.

Bai Hao came back to his senses and said, "Fatty, I can't remember the content of the letter?" ”

"Can't remember?" Zhang Kun's tone was a little surprised.

Bai Hao told Li Erfat, Zhang Kun and Li Gan about what happened to him, although it sounds incredible, but it really happened to Bai Hao.

"It's over, it's over." Li Erpang was a little desperate, "Isn't there even a clue left?" ”

"Looks like the ghost is very cunning." Zhang Kun analyzed, "I think Bai Hao's memory should have been erased by ghosts."

"According to you, the smell of blood is just for us to burn the letter so that we can't find it again." Li Gan was wrapped in a quilt, and after vomiting, he felt that his body had returned to normal.

The three of them were discussing, and Bai Hao, who was in the dark, took out his mobile phone.

At this moment, he sent a faint light from his mobile phone and shone it on the white envelope, looking at the blood-red '444' three numbers on the envelope.

Bai Hao's heart flashed with inspiration, the corners of his mouth were slightly raised, and a smile leaked from his face, at this time he already had a way to find out the ghost.

"It's not early, let's rest first, and we'll talk about the letter in the morning." As he spoke, he closed his eyes.

Although Li Erfat, Zhang Kun and Li Qian were all scared, but after a burst of vomiting just now, they all felt a sense of exhaustion from their bodies, and now the time was already midnight and early morning, and drowsiness also came up, and it didn't take long for them to close their eyes and fall asleep like Bai Hao.
