If Du Bo hadn't come to the No. [-] High School in person today and yesterday, he would have thought it was a different school.

The gloomy and weird atmosphere is completely different from yesterday. Today's Shiyi High School is full of youthful vitality. Every student is so happy and at ease, not at all like yesterday's lifeless look.

Ji Xuanjing was also surprised that the yin and ghost aura that enveloped the school yesterday actually dissipated a lot today.He released the golden thread. Although he still couldn't find the source of the yin and ghost aura, he was sure that all the people in the school were human and there were no ghosts.He poked out anger in everyone.

When they came to the back mountain, the forensic doctor had already placed the corpse on the blue gauze pad beside it.

"Is there still no clue?" Du Bo put on his gloves and lifted the white cloth to observe the wound carefully, and Ji Xuanjing also moved to the side.There is no resentment, and no remnant soul, which is exactly the same as Yuan Lie's situation at that time.But now under the watchful eyes of everyone, he can't call out the tripod to ask the sky.

"Is this the scene of the first crime?" Du Bo stood up, walked into the pothole, and carefully looked at the surrounding soil.Some were blackened, but most were just plain burnt brown.

"Probably not. Such a wound should cause a lot of bleeding. But no fresh blood was found in the pit."

"Hey Officer Du, you're here so early." Just as Du Bo was talking to the forensic doctor, Li Xun ran over with a whimper.

In an instant, Ji Xuanjing stepped forward suddenly, drew out the sword of princes, and used the back of the sword to block Li Xun's slowly approaching body.

Obviously in the eyes of outsiders, Ji Xuanjing didn't seem to use much force, but Li Xun took several steps back as if he had been hit hard.

The people present were a little confused about the situation, they only saw this person call Du Bo, and then he was stopped by Ji Xuanjing.But Ji Xuanjing's face was full of frost, and she stared fiercely at Li Xun.

Du Bo, on the other hand, understood Ji Xuanjing's movements in an instant, and pulled him back a few steps calmly, away from Li Xun.

"Officer Ji, what are you doing?" Li Xun Zhang Er was puzzled.He just came to cooperate with the work, why was he suddenly pushed away?

Ji Xuanjing was about to speak when suddenly her eyes became suspicious.He clearly felt such a strong ghost aura just now, why did it disappear in an instant?After that, no matter how Ji Xuanjing felt, the strong ghostly aura seemed to disappear out of thin air, and she could no longer feel it.And Li Xun was angry again, obviously he was a real person.

Li Xun came over angrily, but he didn't dare to criticize Ji Xuanjing and Du Bai.

"The school discussed it yesterday and said that since I have met several police/officers yesterday and had preliminary exchanges with you, they decided to let me assist your investigation."

"Alright." Du Bo nodded, "Where was Director Li last night?"

"Ah? Last night?" Li Xun didn't understand why Du Bo suddenly asked him this question, but he answered honestly: "Last night I sorted out the materials very late, and went to bed after sorting it out."

"Didn't anything unusual happen?" Du Bo asked persistently.

"Abnormal? No? Oh, by the way, I don't know if it counts as abnormal. Was there a strong gust of wind last night? It knocked on my window, which shocked me. I went to the window to look later, and it didn't look like there was wind outside."

Du Bo has always been a light sleeper, and he knew very well that there was no wind last night, let alone a strong wind like the one that "could knock the windows out" as Li Xun said.

"Take me to your dormitory." I'm afraid what Li Xun heard last night was not the wind, but the news of the murderer.

"Ah? Oh, okay." Li Xun nodded, "Officer Du, aren't you here for a while longer?"

"Captain Du, we are here." The police officer in charge of on-site investigation shouted at Du Bo.

"Thanks for your hard work."

Du Baiji, Xuanjing and Li Xun walked to the staff dormitory together.During the trip, they met many enthusiastic students. They regarded them as the parents of the students, asked them enthusiastically if they needed help, and wanted to introduce them to Shiyi High School.Every time Li Xun met a student, he would say "hmm" next to him, which seemed to be a warning.

Some students met Du Bo and Ji Xuanjing yesterday, and Du Bo could clearly see that these students were facing them with stiff smiles, and he knew in his heart: I am afraid this is another task assigned by the school.

To Du Bo's surprise, the staff dormitories of the school were actually bungalows.They also visited here yesterday, and they were still guessing what these old-fashioned one-story houses that were incompatible with the modern campus were used for, but they never thought that this place was actually a dormitory.

"I live in the outermost room, and I haven't changed it for decades." Li Xun said, pointing to a bungalow.

"Originally this was a double dormitory. After Teacher Gu left, I was the only one left to live here. Later, when I was promoted, the school wanted to change a dormitory for me, but this was originally a double room, and the house was quite big, so I proposed I want this dormitory."

Du Bo walked around the bungalow and found nothing unusual.He looked back at Ji Xuanjing, and got negative news.

"Which window did you hear yesterday?"

"This one." Li Xun led Du Bo and the others to the front without hesitation, pointing to a door facing the entrance path.

"Why does Director Li remember so clearly?" Ji Xuanjing narrowed her eyes and looked at Li Xun.

"There's nothing I can't remember. I was sorting out the materials in the study at the time. There is only such a window in the study. If I can't remember, I can go to the hospital to see my head."

Indeed, looking in through the window Li Xun pointed out, one can see bookshelves, tables and various materials inside.Li Xun didn't lie either, there was only this window in the study.

Du Bo approached, squatted down and carefully looked at the window sill, trying to find any clues from above.The window sills are the old-fashioned ones made of white cement, which are very uneven.It was covered in dust and some dead bugs, it looked like it hadn't been cleaned in a long time.There were no traces of being trampled or pinched on the window sill, and there was no blood.

The outside of the window is also covered with a thick layer of mud. Judging from the shape and traces, it is estimated that it is the rain stains left by not cleaning the glass after the rain.

"Aren't you cleaning the windows?"

"Hey, this house should only be lit in the study room. Usually, as long as the sunlight can shine in, it will be dirty anyway, so there is no need to be so diligent."

After walking around, Du Bo didn't find any suspicious traces around Li Xun's dormitory, not even the grass on the ground was trampled on.Suddenly, Du Bo noticed with sharp eyes that a yellow horn appeared in the grass under a tree not far from the bungalow.

"What is this?" Du Bo walked over, while observing Li Xun's expression secretly, and found that he was nervous for a moment, so he ran under the tree even faster.

Push away all the green grass, and there is a brass-colored pot covered underneath, with a pile of ashes inside.

Du Bo's first reaction was to burn the corpse and the evidence, and quickly put on his gloves to shake out some dust inside.Sadly, these appear to be only the remains of paper that was burned to ashes.

"Is this your thing?" Du Bo asked looking at Li Xun with a hard-to-speak expression.

"It's mine, oh, why did you see it." Li Xun sighed, "This is the blind spot of surveillance that I found with great difficulty. I thought it was well hidden."

"What is this, why are you hiding it?" Du Bo felt more and more that there was something wrong with Li Xun.

"Paper money basin?" Ji Xuanjing had seen this thing before, but he was not sure.

"Yes, it's a paper money basin."

"Once Mr. Gu's incident happened, the school kept silent about him, and he was not allowed to be mentioned, let alone commemorate him. Every time I think about what happened back then, I would come out and burn some paper money for him, but no one would find out. I was only responsible for installing a part of the school’s surveillance system, and my dormitory happened not to be in this part, so I could only look for it secretly, and finally let me find this blind spot.”

"Why don't you burn it in the room?" Ji Xuanjing didn't understand, since there was no surveillance in the room.

"Fire prevention and theft prevention, smoke alarms are installed in every house in the school, and water will be watered whenever there is smoke, so I am not afraid that I will be exposed faster?" Li Xun said proudly.

"Last night, I burned some paper money for Gu Chaoyang, and not long after I went back, I heard the window slamming. At that time, I thought it was Gu Chaoyang who came back to see me." Li Xun chuckled, but what he said was that Creepy words.

That's why Li Xun had a ghostly aura this morning?Is that Gu Chaoyang?Ji Xuanjing thought, maybe Gu Chaoyang really came back last night, and was able to temporarily stay by Li Xun's side through Li Xun's strong thoughts, but he was beaten away by his sword this morning.But didn't Gu Chaoyang die of illness, how could he have resentment, how could he become a ghost?

Ji Xuanjing was puzzled, and the answer might lie in Li Xun.There are still many things he has not said, and will not say.

Li Xun didn't get any useful clues here, so Du Bo could only leave with Ji Xuanjing.

"It's almost time for classmate Tao's speech. Officer Du and Officer Ji, are you interested in listening to it?" Li Xun looked at his watch and found that the time had already reached 9:47.

Du Bo planned to go and have a look, but Ji Xuanjing slipped away with the excuse of having a stomach ache.He was going to the pavilion last time, and he remembered that there was also a blind spot for surveillance.Although he could completely hide himself by relying on spells, he still went to the pavilion in order not to cause unnecessary trouble and add double protection.

As for Gu Chaoyang, he wanted to find out whether his soul had returned to the underworld or stayed in the human world to do evil.

"Today there are descendants of the Gu family with the surname Ying, who were wronged and died. How did you hear about it? Please Jane."
