After leaving the back mountain, Shu Tianyu did not go back to the dormitory directly, but took Lan Yu'er directly to the Demon Spirit Bureau to let a professional person test the cigarette butts.

The cigarette butt has saliva residue on it, and there is DNA of the murderer, as long as it is detected, it can be compared through the citizen's database, and the murderer may be identified.

"Tianyu, brother and sister, why are you here?"

Shu Tianyu and Lan Yu'er had just walked into the office when they were noticed by Huang Daxian who stayed in the office.

"Come and investigate some things, the case that happened in our academy this morning, have you heard that the sophomore civilian genius was abolished by someone in the mountain behind the academy."

After Shu Tianyu pulled Lan Yu'er to sit down, he said loudly.

"I heard about it, but for the time being, it's your academy's internal self-inspection, if necessary, our Demon Spirit Bureau will take action again!"

Wong Tai Sin said aloud.

After all, Deepwater University is not an ordinary place, although the Demon Spirit Bureau also wants to take action as soon as possible, but it has to take into account the face of Deepwater University, and they will not go over privately before Deepwater University speaks.

"I've already gone to the scene to see it, and found a cigarette butt, which should have been left by the murderer, now come here to find someone to test the residual DNA, and then compare it with the citizen database."

While Shu Tianyu spoke, he also took out the cigarette butt sealed in the plastic bag and put it on the table.

"Awesome, just leave this to me, I'll help you find someone to test, you wait here, at most an hour, the test results will come out."

After Wong Tai Sin finished speaking, he took the test results and left.

Shu Tianyu and Lan Yu'er sat in the office and drank tea while waiting.

Half an hour later, Wong Tai Sin hadn't come back, and Yege and the others went out to work, but they came back.

"Tianyu, when did you come over?"

Seeing Shu Tianyu, Yege couldn't help but ask with some surprise.

"Not long after I came over, I was ready to investigate the case that happened in the mountains behind Shenshui University this morning!"

Shu Tianyu said aloud.

Then he briefly talked about his findings and the fact that Wong Tai Sin had taken cigarette butts to test.

"I see, then you have to seize the opportunity, if you succeed in solving the case, I will help you ask for credit!"

Night Song said aloud.

He had also heard about what happened in Shenshui University, after all, it was not a trivial matter, and these things were also under their control, but because of the face of Shenshui University, they had not intervened for the time being.

"This is not certain, even if you find out who the murderer is, you may not be able to find anyone!"

Shu Tianyu shook his head and said.

The reason why there are so many wanted criminals on the Internet is because these guys are too shrewd, and after committing the crime, they changed their faces as soon as possible and chose to escape.

In this era, it is almost impossible to find people as long as you hide in the hunting area.

Not long after, Wong Tai Sin also came back with the test results, and then Shu Tianyu used his authority to log in directly to the citizen database and start comparing.

Soon the same set of DNA was found, and the target was found.

[Target person]: Ren Hongfei

[Target Information]: Graduated from the 89th class of Shenshui University, he was recruited by the He family in Shenshui City, belonged to the He family's guards, and the level of the spirit master was level 40......

"It seems that it should be right, the perpetrators are very familiar with Shenshui University, I suspect that the He family was unsuccessful in recruiting Li Shanhe, so they chose to be ruthless."

While Shu Tianyu spoke, he also directly projected the information.

"It's from the He family again, it's really too much!"

Night Song said coldly.

For the He family in Shenshui City, he is naturally clear, although he is not arrogant, but he has done a lot of bad things in secret, but he can't get evidence.

"Don't worry, let them vomit blood this time!"

Shu Tianyu smiled slightly.

He doesn't need to do anything, he just needs to hand over the evidence to the teacher, and then let the teacher hand it over to the dean, and he doesn't have to worry about the rest.

"What are you going to do?"

Huang Taixian couldn't help but ask curiously.

"This is simple, I just need to hand over the evidence to our dean, with the dean coming forward, it will be difficult for the He family to admit it even if they want to, so they will definitely have to pay the price this time."

Shu Tianyu directly said his plan.

Although it is not good for him to do this, he is happy to be able to make the He family suffer, after all, He Bufan and He Buregret are his opponents.

"This method is good, with Dean Li Qinghua taking action, the He family will definitely bleed heavily."

Yege also nodded.

Although he has not studied at Shenshui University, he is naturally familiar with Shenshui University in Shenshui City.

Li Qinghua, the dean of the famous Shenshui University, is naturally familiar with them.

"I'll go back first, in order to avoid long nights and dreams, this evidence must be handed in early!"

After Shu Tianyu finished speaking, he stood up, then pulled Lan Yu'er and prepared to leave.

After returning to the academy, Shu Tianyu contacted the head teacher Hong Danqing, he was just a student, and it was not easy to see the principal, but the teacher could.

"Tianyu, you are in such a hurry to find me, what's the matter?"

As soon as Hong Danqing came over, he asked out loud.

Shu Tianyu directly projected the evidence, and said loudly at the same time: "Teacher, I have found the murderer, this is the evidence I found through the relationship, you can take a look." ”

Hong Danqing's expression froze, and he immediately looked at it carefully.

"Okay, great, you send it to me, and then I'll go and hand it over to the principal, and you don't have to worry about the rest, so as not to cause the He family's revenge."

Hong Danqing said out loud.

The first thing he considered was Shu Tianyu's safety, so he didn't want Shu Tianyu to interfere too much.

"Understood!"

Shu Tianyu nodded, and then directly sent the evidence to Hong Danqing.

Then Hong Danqing left in a hurry.

It didn't take long for the evidence to reach the hands of Dean Li Qinghua, and without Li Qinghua being directly angry, he took several masters of the academy and went directly to the He family to get someone and let the He family give an explanation.

"Old ghost He, get out of here, otherwise I will smash your He family's manor."

Li Qinghua led people to appear directly above the He family's manor, shouting loudly, like thunder rolling, and the momentum was terrifying.

In the forbidden land of the manor, an old man soon rose into the air.

"Dean Li, our He family didn't offend you, did we?"

The head of the He family said in a deep voice.

At this time, he didn't know what was going on, after all, he rarely interfered in the affairs of the juniors below, and he didn't know about Li Shanhe's abolition of the dantian at all.

So at the moment he was confused.

"Your son's personal bodyguard, Ren Hongfei, abolished a genius student of our academy not long ago, if you don't give an explanation, you will be leveled today."

Li Qinghua said in a deep voice.

Ren Hongfei's origin has also been investigated, and it is the son of the head of the He family, that is, the subordinate of He Bu's father.
