"You brought the evidence with you, right?"
"We brought Dean Li; he's in the box," the forensic doctor quickly replied.
"Let's go then, we can talk as we walk."
On the way to the lab, Li Chu glanced at the three people looking over and said, "I remember you two went there to study, right?"
“That’s right, Dean Li, we were both in the third batch.”
"You should know about this DNA, right?"
"I know, I saw them do it there, but we never imagined that this technology could be used in solving cases." Li Desheng smiled a little embarrassedly.
"I didn't expect it to be alright. There's a first time for everything. After this is done, you two can both write a report on this technology. This can be considered a breakthrough in criminal investigation technology."
"Thank you, Dean Li."
"You're welcome. I've been friends with your Director Zhang for forty years. Wang Jiadong from your Criminal Investigation Team is my nephew."
"We, the military and police, were originally one family. Twenty years ago, you belonged to the public security forces; it was only later that we separated."
...
As they were talking, the group of four arrived at the laboratory building.
Because he was accompanied by outsiders, Li Chu couldn't just walk in directly, so he called Director Sun from the sentry post downstairs.
Within two minutes, Director Sun, wearing a white coat, rushed out and invited Li Chu and the others to the meeting room next door.
"Dean Li, these three police officers are..."
"Here's the thing, Lao Sun. I've got a job for you guys. Our police have a case where they have some bloodstains left by a suspect when he fled. They've also caught another suspect, and the blood type of the person they caught matches the bloodstain. But this person keeps protesting his innocence. So, we'd like to ask you to do a DNA test to see if the bloodstain actually belongs to this person."
Director Sun was also hearing for the first time that DNA technology could be used to solve cases, and his face showed obvious interest.
"Hey, who came up with this idea? It's totally feasible, but..."
Director Sun looked at Li Chu, then at the three police officers, hesitated for a moment, and said, "Dean Li, as you know, this costs money, otherwise I can't get reimbursed."
“I know, I’ve already told them. Give me a price.”
"One thousand yuan?" Director Sun thought for a moment, then slowly held up one finger.
The three men's eyes nearly popped out of their sockets. Good heavens, this is way too expensive! How much was their total budget for handling the case?
"Don't ask for a thousand, give me five hundred. If we succeed this time, I believe that the police will definitely come back when they encounter similar cases in the future, and maybe even in other places."
Director Sun felt a toothache upon hearing this. This thing didn't have a set price to begin with, and they had never sold it to the public before, so the price was entirely up to them. But this price-cutting was just too ruthless.
However, when he thought about how all the imported equipment in the laboratory building had been secured by Dean Li, he lost the courage to continue haggling and could only nod reluctantly.
"Forensic Doctor Li, have you brought enough money?"
Li Desheng was speechless. When they came over this morning, the bureau gave them 500 yuan, and the bureau chief even told them to try to negotiate a lower price. Now what? What price could they negotiate? If they dared to say anything, the price would probably go up even further.
"I've brought enough, I've brought enough."
Then it was easy: pay here, get the invoice there, and then hand over the blood you brought to the lab staff.
Director Sun stared blankly at the few cotton swabs in the bottle.
"No, officer, you're not going to tell me it's blood from this cotton swab, are you?"
"Yes, this is the bloodstain we collected. The other test tube contains the suspect's blood."
"What a loss!" Director Sun picked up the bottle and examined the cotton swabs for a long time, muttering to himself.
"Alright, Lao Sun, stop talking about losses. How long will it take to get the results?"
"At the fastest, within a week."
"Okay, let me know when the results are out, and I'll notify them."
"No problem, Dean Li."
"Oh, right, Lao Sun, you absolutely mustn't contaminate the sample; it's evidence for the police."
Director Sun's mind was clearly elsewhere; his eyes were fixed on the bottle, and he waved his hand dismissively, saying, "Don't worry, our lab has strict regulations."
"I won't see you off, Dean Li. I plan to do this myself."
"Go ahead, go ahead."
As Li Desheng emerged from the meeting room, he glanced at Li Chu with some curiosity: "Dean Li, you seem quite familiar with this place."
"What's there to be familiar with? I've only heard Jia Dong mention it occasionally."
In fact, in this era, confessions are valued more than evidence; there is no such thing as handling a case without a confession.
That's why, plus the constant talk of time limits, so there's no way to get a confession? There are just too many methods... (cough, you know what I mean.)
After the three police officers left, Li Chu changed into a white coat and came to the outpatient hall.
As soon as I entered the outpatient clinic, I ran into an acquaintance—no, I should say two acquaintances.
"Teacher Ran?"
"Uh... Hello, Dr. Li."
Wow, even the way they address each other has changed. Li Chu raised an eyebrow.
"Qiuye, who is this?"
That's right, he ran into Ran Qiuye, and the man he saw on the bus last time was also their school's physical education teacher.
"Oh, Changping, this is the parent of one of the students I taught before, and also a doctor at this hospital."
"Oh, Dr. Li, hello. My name is Liu Changping, and I am Ran Qiuye's husband."
His words caused an unnatural look to flash across Ran Qiuye's face, as if she dared not face Li Chu, and she lowered her head slightly.

"Hello, Ms. Liu, you also taught physical education to my child."
Li Chu reached out and shook hands with Teacher Liu.
"What brings you two to the hospital?"
"Dr. Li, Qiuye is pregnant, and her morning sickness is quite severe, so we came to check on her."
"How many months?"
"It's been three months already."
Li Chu looked at the packaged Chinese medicine in his hand and nodded. Just as she was about to say something, she saw Ran Qiuye secretly tugging at her man's clothes, and she immediately stopped talking.
"Dr. Li, which department do you work for?" Liu Changping felt his wife tugging at his clothes, but he pretended not to know and continued talking to Li Chu.
"I'm a traditional Chinese medicine doctor. Um, Teacher Liu and Teacher Ran, I have some things to take care of inside, so I'll have to go now. Come find me next time you come."
After saying that, Li Chu left without looking back.
"Hey, this guy is really something. I wanted to ask him something." Liu Changping muttered with some dissatisfaction.
"Changping's gone, Dr. Li probably has something to do. Let's go home quickly." Ran Qiuye breathed a sigh of relief after Li Chu left.
