After coming out of Xu Zhiguo's building, Su Le and the others met Mr. Wang who played chess together that day downstairs.

"Hello, Mr. Wang!" Zhang Pengfei greeted him warmly.

"Okay, when will the young man have time to kill me for two sets?"

"No problem, I'll come to you for advice when the case is solved."

Several people were standing downstairs and talking. The fool Su Le and his friends met that day came over happily again. He was still muttering as he walked:

"One two three four five, hehe, one two three four five, hehe, one two three four five, hehe."

"Isn't this Xu Zhiguo's youngest son?" Su Le still remembers what Xu Zhiguo said to them that day.

"Yes, his name is Xu Wenkai. He was a very good young man in the past. He didn't know what was stimulating, but he became like this."

"Oh, he has been stupid since he was a child?" Su Le asked.

"No, he suddenly got a serious illness during the demolition of the old village and became stupid. Some people also said that he was scared to death."

"Smiling all day, it's good to look carefree," said Liu Guan.

"No, he is also afraid. People say that he dare not go out when it rains, and he never dares to go to Meijing East Street." Uncle Wang said in a low voice.

"Uncle, is there anything scary on Meijing East Street?" Liu Guan asked.

"Not there, isn't that the same as other streets?"

"Then why didn't he dare to go?"

"I don't know, once a few troublemakers deliberately scared him and carried him to the East Street. He was so scared that he peed in his pants."

"There is such a thing?" Su Le asked in confusion.

"Yes, we don't understand. The person who is happy all day long just doesn't dare to go to East Street, as if there are ghosts there." Mr. Wang said.

"Ah, there is such a thing. I have seen those who are afraid of ghosts, but I have never seen those who are afraid of the streets." Liu Guan's face showed a look of surprise.

"Have he said he was afraid of something?" Su Le asked.

"We haven't heard him say that." Uncle Wang shook his head and replied.

When Su Le and the others bid farewell to Mr. Wang and left Meijing Community, Dr. Qiao, who had not spoken suddenly said:

"Let's go to Meijing East Street for a walk."

"What do you want to try how scary it is, haha." Liu Guan asked.

"Yes, go and see what's scary." Dr. Qiao continued his words and answered.

Meijing East Street is no different from other South Streets and North Streets. Even the width and narrowness of the roads, the style of street lights and the design of greening are exactly the same. The only difference is that East Street only has commercial door-to-door houses on one side of the community, and other streets are door-to-door houses on both sides. Opposite to East Street is an abandoned factory.

"If that fool is really scared of this street, I think it must be related to this factory." Dr. Qiao said to himself.

"Okay, Dr. Qiao, you are going to change to a psychiatrist." Su Le quipped.

"There may be a way to cure that fool's disease, at least it can relieve him." Dr. Qiao said, looking at the abandoned factory outside the window.

"Just a fool, do we need to treat him?" Zhang Pengfei asked.

Dr. Qiao did not answer Zhang Pengfei's question, but leaned against the car window and closed his eyes and thought about his thoughts. After a long time, he opened his eyes and asked:

"Liu Guan, what are the better hospitals in Gui'an City?"

"Ah, hospital? Doctor Qiao, do you want to see a doctor?" Liu Guan asked in confusion.

"You're just answering the question."

"Oh, the best things here are the Municipal People's Hospital and the Medical College Affiliated Hospital."

"Which of these two hospitals is closer to here?"

"People's Hospital is close to it, just one kilometer away here."

"How about this, how about we split into two groups? Su Le and I went to the hospital, Pengfei and Xiao Liu went to check the call records?" Dr. Qiao solicited everyone's opinions.

Everyone didn't know what Dr. Qiao sold in the gourd, and he didn't seem to want to explain anything, so he could only agree to his arrangement. Liu Guan drove to the door of the People's Hospital, and then went to the mobile company with Zhang Pengfei.

"Which department will we go to?" Su Le asked Dr. Qiao.

"Go to the hospital office first." Dr. Qiao replied.

"What are you doing in the hospital office?"

"Go and see if you can find the medical record of that fool. I want to know when he got sick."

"Do you think his illness is related to the case?"

"I can't confirm it yet, I just think I should check when he got sick."

"I also think this fool's thing is a bit strange, but the clues we have obtained at present cannot be linked together, and we cannot catch the key to the problem."

"Maybe we can catch the key by finding the specific date of his onset."

The people from the hospital office warmly welcomed them. After listening to their demands, they directly took them to the hospital's information archives department.

"When do you want to check the medical records?" The person in charge of the Information Archives Department was an elderly woman, and the person in the office called her Chief Lin.

"January and February 2005." Dr. Qiao inferred that Xu Yongchang's death was February 4th, and the time when the fool's onset should also be around this date.

"Oh, that's a bit troublesome. At that time, our hospital had not yet achieved office electronicization, and all were paper files. And the diagnosis records of the outpatient part were not archived in our hospital."

"That's OK, we can only check the hospitalized part."

"Then which department do you want to check the hospitalization records?"

"It should be a neurology." Dr. Qiao was originally a medical student, and he was still very clear about what subjects should a patient who suddenly went crazy.

"Okay, come with me upstairs." After Chief Lin said that, he twisted her fat buttocks and led the way in front.

The hospital's archive management is indeed very standardized, and each year's medical records have separate rooms to store. Section Chief Lin led them directly to the archive room with the 2005 sign hanging, and opened the door and let them in.

Perhaps it was because of the long-term lack of ventilation, or it might be because the medical record was still stained with the ward and there was a dirty smell in the room. Chief Lin walked over and turned on the ventilation device. After a while, the air in the room became normal.

There are a large stack of medical records in the Department of Neurology every month. Su Le and Dr. Qiao each are responsible for one month, and carefully examine the medical records for January and February respectively. An hour has passed, and Su Le and the others have read all the medical records on hand, but have not found Xu Wenkai's name. Chief Lin has been waiting a little impatiently and is walking back and forth in the corridor.

"Did we find it wrong?" Su Le asked.

"It shouldn't be, maybe it's a matter of time." Dr. Qiao walked to the door and asked Chief Lin who was standing in the corridor:

"Chief Lin, is the medical records of your hospital based on the date of admission? Or the date of discharge."

"Of course it is the discharge date. We require each department to complete the archiving work on the month when the patient is discharged." Chief Lin replied.

"Look for March." Dr. Qiao came back and said to Su Le.

Hard work pays off. After more than half an hour of searching, they finally found Xu Wenkai's name in the medical records in March.

After copying all Xu Wenkai's medical records, Su Le and the others took a taxi back to the police station. On the way back to the police station, Dr. Qiao asked Su Le to call the people in the bureau to inquire about the meteorological data of Gui'an City in January and February 2005.

Deleting the call records on your mobile phone does not bring much difficulty to the case investigation. Liu Guan quickly retrieved all the call records of Xu Zhiguo within one month with the certificate issued by the police station.

After both groups of people returned to the police station, they immediately came to the office of the detachment leader Hu Jianzhong to report on their work.

"You talk about the call records first. I'll take a look at the weather information first." Dr. Qiao said to Zhang Pengfei.

Zhang Pengfei said with the call record printed from the mobile company:

"The call record shows that after Su Le and his friends left the Xu family, Xu Zhiguo called 5 calls in total. The first call was to his eldest son Xu Wenliang, the second call was to his brother-in-law Guo Encheng, the third call was to Xu Wenliang, the fourth call was to Guo Encheng, and the fifth call was to Xu Wenliang. A month before Su Le and his friends went to the Xu family, Xu Zhiguo called only three times, twice to Xu Wenjuan, and once to Xu Wenyong."

"From the call record, it is not difficult for us to guess who was the person who deleted the call record." Su Le said to Zhang Pengfei.

"Apart from Xu Wenliang and Guo Encheng, others will not be interested in call records." Liu Guan said.

"Xiao Liu, tell me about Xu Wenliang's information I found." Zhang Pengfei asked.

Liu Guan took out his notebook and said:

"Xu Wenliang is 48 years old and is the owner of Gui'an Daliang Construction Company. Daliang Construction Company was established in 1995 with a registered capital of 500,000 yuan. Last year, the invoice amount of Daliang Construction Company was 76 million yuan, and it is a small construction company in Gui'an. It mainly does some small construction and installation work and undertakes subcontracting work of some large construction companies."

"This Xu Wenliang seems to have some strength," said Zhang Pengfei.

"Yes, Dr. Qiao, have you gained anything in the hospital?" Hu Jianzhong said to Dr. Qiao, who was looking at the weather information.

"We found Xu Wenkai's hospitalization record in the hospital." Dr. Qiao replied.

"Can you find any clues from the case?" Zhang Pengfei asked.

"According to the diagnosis records when Xu Wenkai was admitted to the hospital, he fell ill on the evening of January 28, 2005. He was sent to the hospital on the morning of the 29th. The patient's symptoms were 39.5 degrees of fever, unconsciousness, and severe tremors. At that time, the hospital gave antipyretic and stable drugs, and was diagnosed with a mental disorder of stress response." Dr. Qiao said with his medical record in the office.

"What then?" Hu Jianzhong asked.

"I then checked the meteorological data for January and February 2005. Throughout January and early February, it was raining only on the evening of January 28, and the precipitation record that day was 15 mm per hour, which was fully consistent with the characteristics of heavy rain." Dr. Qiao said holding the meteorological data.

"Oh, I understand!" Su Le jumped up from the chair excitedly.

Except for Dr. Qiao, everyone else stared at Su Le wide, hoping that he would give further explanation. Dr. Qiao showed a satisfied smile on his face, pulled over the chair Su Le had just sat on, and leaned on it casually waiting for Su Le's explanation.
