That place is too evil. I am a person of righteousness and cannot go there to offend the evil spirits inside.

In the end, it was still me who was left with nothing to do.

"This is the headache of being a leader!"

Li Nan hesitated for a moment, then thought, "I should go and check on Liu Xiangdong's interrogation!"

Yang Bairong, who obtained the arrest warrant last night, immediately led his men to arrest Liu Xiangdong.

It wasn't too late then, and it's said that this guy was still on the school playground, pouring his heart out to a female student.

When he was arrested, he kept shouting that he was innocent, and even told his junior to take care of him and that they would meet again when he got back.

Looking at Liu Xiangdong's damp pants, Yang Bairong said disdainfully, "With looks like that, you still want to pick up girls? Take him away!"

Looking back at the lonely, tear-streaked junior schoolmate, he wondered, "Why am I a single dog? Am I that ugly?"

After being left out all night, Liu Xiangdong finally regained some of his former self as the president of the student association.

Imitating scenes from movies and TV shows, I shouted loudly, "Lawyer, I need to find a lawyer!"

Even the student council president was too naive to fight back against the professional and experienced police officers of the Anti-Corruption Bureau.

However, the results of the interrogation were not very useful.

The interrogators could tell that Liu Xiangdong wasn't lying, but his testimony consisted of "I don't know," "I really don't know"...

"I just wanted to follow her into the plum grove to see who she was dating."

"And what happened? You killed him?"

"Although we went in one after the other, I really didn't see her. I walked around for a while but still couldn't find her, so I left. There are security cameras; you can check them!"

Li Nan, standing outside the room, looked at Liu Xiangdong through the one-way glass and scratched his forehead. "Another stupid teacher. It was the surveillance footage that brought you here!"

"Captain Li, a major discovery! A major discovery!"

Holding a stack of documents, Li Na hurriedly found Li Nan outside the interrogation room.

"Just as I thought!"

Although the two cases from four and eight years ago were suppressed due to various personal relationships, the brother unit of Beiwei still collected and organized the information from that time very well.

After all, engraving on the back is a very unconventional operation, so there are more than ten photos of this part, taken from various angles.

"Fallen apricot leaves, yellow and gone, the sea of ​​learning boundless, no boat to cross. Indeed, this is the content of the Plum Blossom Academy. Strange, why are only the middle two lines missing, and not the first line?"

An uneasy feeling rose in Li Nan's heart. This was never going to end.

"Are all the documents complete?"

Before Li Na could answer, Li Nan had already guessed it herself; such an obvious clue couldn't possibly have been overlooked.

Thinking it was her fault for not doing her job properly, Li Na quickly explained, "The information provided by Beiwei is all here. The case from eight years ago is too far back, so we only have paper documents and photos. For the case from four years ago, we have some video footage."

However, due to obstruction from the school, no video surveillance footage from the school was collected at the time!

"A society based on personal connections is harmful!"

Seeing Li Na's nervousness, Li Nan comforted her, "Li Na, you've done very well. The ones who were in charge at the time were the ones who made the mistake!"

Whether it's a school or a patrol station!

The interrogation in the interrogation room was still going on with little progress, a grueling interrogation, when thankfully, another piece of good news arrived.

"Captain Li, guess what we found?"

As soon as the talent arrived at the door, Yang Bairong greeted them with a bright smile, shaking his newly bought work bag.

"Could they have found the murder weapon?!"

Li Nan made a guess on the spot.

"Tch, this is boring. Captain Li is really amazing; he guessed so accurately!"

Yang Bairong walked up to Li Nan and handed her a glass of water. "Thank you for your hard work, leader, personally overseeing the interrogation!"

Li Nan was basically immune to the tricks of old hands like Yang Bairong, so he interrupted him and asked, "Hurry up and tell me, where did you find it?"

At first, Yang Bairong and his team did not find anything useful in their search of the school, but then a colleague said something.

"Nowadays, college students like to rent apartments and live together, and we seem to have overlooked this aspect!"

Yang Bairong slapped his forehead. Indeed, it was an oversight, a real oversight!

So the group found Liu Xiangdong's classmate, and without much effort, they found the shared apartment that Liu Xiangdong and his classmates lived in off-campus.

The location of this physical evidence is even more bizarre. It just goes to show how novels and movies can mislead people.

The murder weapon was inside the toilet tank, covered in blood and carefully wrapped in several layers of plastic wrap.

"What an idiot!" Li Nan exclaimed again upon hearing this. What a hothead! This time, he was bound to commit murder on impulse.

Having found the murder weapon, Yang Bairong and his group rushed back to the Anding Division in high spirits to claim their credit, and the murder weapon was sent to the Trace Evidence Department for examination.

It seems that Qin Wen, who was sulking last night, has something to do again.

The test results came back quickly. Holding the test report, Qin Wen tossed the folder to Li Nan with a stern face.

"See for yourself!" Qin Wen said angrily.

The DNA test results were very clear: blood residue was found on the murder weapon, and it matched the victim's DNA perfectly.

Even more remarkably, the weapon's handle was made of wood, and three other sets of dried bloodstains were found in the crevices.

With today's advanced technology, after testing and matching, the DNA surprisingly matched the DNA of the victims in two cases sent by Beijing Satellite TV.

"What a pleasant surprise!" Li Nan never expected that this accidental search for physical evidence would lead to useful clues for two old cases.
