I'm a criminal investigation major, and you want to take me to fight drug trafficking?

As soon as Li Xuan left home and got into the car, the cell phone in his pocket rang again.

He took out his cell phone and looked at the caller ID. It was still Guan Cai calling.

So after he answered the phone, he asked Guan Cai on the other end of the line.

"Guan Cai, what's wrong?"

Guan Cai asked Li Xuan in a very anxious tone at this time.

"Master, when can you come to the Municipal Bureau?"

Li Xuan showed a look of surprise when he heard this, but after thinking for a while he continued to speak to Guan Cai.

"I don't know yet, what happened?"

Guan Cai's eyes suddenly turned dark when he heard this and he couldn't help crying in his heart.

"No, Master, were you just teasing me?"

But after a moment he hurriedly spoke into the phone.

"Master, something big has happened! A strange serial murder case has occurred on Yellowstone Road."

"All those killed were our police officers. We rushed back from Qionghai City to investigate."

"But this case is so strange, it's like seeing a ghost. I don't know how to start!"

"Please come back to the Municipal Bureau as soon as possible!"

Upon hearing this, Li Xuan realized the seriousness of the matter and quickly spoke into the phone.

"I'll be there soon!"

As soon as he finished speaking, he hung up the phone and hurried to the Municipal Bureau.

Fifteen minutes later, at the entrance of Guangzhou-Shenzhen Municipal Bureau.

"Squeak!" Followed by the sound of tires rubbing rapidly.

A Hongqi stopped in the parking lot of the Municipal Bureau, and Li Xuan jumped out of the car almost instantly.

He hurried to the temporary office of the Municipal Bureau and saw Guan Cai scratching his head and asked hurriedly.

"Guan Cai, what's the situation with the case?"

Guan Cai raised his head when he heard this and saw Li Xuan rushing towards the door. He spoke to him with red eyes.

"Our colleagues at Yellowstone Road have committed suicide one after another. Ten people have died this month alone!"

"All the victims were police officers from the police station. Now most of the police officers from the Huangshi Road Police Station have died."

“I don’t know how to investigate this case further…”

Li Xuan was stunned when he heard this, and a bad premonition arose.

The case of police officers committing suicide one after another sounds quite outrageous.

Logically speaking, it's impossible for a police officer to commit suicide for no reason! Even this idiot knew there must be something wrong.

Not to mention that Huangshi Road was his first stop on his police career and he basically knew everyone there, so there was no possibility at all.

Thinking of this, Li Xuan asked Guan Cai in front of him.

"Where did the crime take place?"

Guan Cai immediately responded upon hearing this.

"The ten deceased were found almost throughout the entire Guangzhou-Shenzhen city."

"And I checked their medical records, and all of them have no hidden diseases and are healthy."

"I haven't seen any bad habits in their records."

As he finished speaking, he handed Li Xuan a stack of files.

Li Xuan frowned when he heard this. He felt that there was something wrong with this case.

He took the file from Guan Cai and started to read it. Guan Cai continued to speak to Li Xuan.

"Master, all ten police officers are on duty in pairs."

"There were two auxiliary police officers involved and I didn't see them handle any cases together."

Li Xuan nodded when he heard this. This was a common point, which could rule out the possibility that he was not being retaliated against for participating in a collective case.

However, this only eliminates one possibility rather than providing a direct clue.

He picked up the first file and opened it, and a photo caught his eye first.

He was a young police officer wearing a police hat and looking energetic.

The first impression he gives is that he is young and energetic.

When Li Xuan saw the police officer in the second photo, he was stunned.

The person above was actually his master, Xu Guodong!

His face in the photo was as pale as paper, without a trace of blood.

He was stabbed more than a dozen times and blood was all over the floor.

This was taken after his death. Xu Guodong was lying on his back on the ground wearing a police uniform.

The silver watch on his right hand seemed to have stopped swinging due to the impact and was stained with blood.

When Li Xuan saw this, he couldn't help but shed tears.

He asked Guan Cai while choking back his emotions.

"Where is Director Zhou?"

Guan Cai was about to tell him when he heard this, but when he saw the tears dripping down, he was suddenly stunned.

This was the first time he saw Li Xuan cry in all the time he had studied with him.

At a loss, he asked Li Xuan softly.

"Master...Father, Master, what's wrong with you?"

But at this moment, Li Xuan seemed to be unable to hear his words.

Still trying to suppress the blurry vision, he raised his head and looked at Guan Cai in front of him and asked.

"Where is Zhou Ming?"

Seeing this, Guan Cai immediately spoke to Li Xuan.

"in office!"

Upon hearing this, Li Xuan took the file and walked out the door without looking back and came to the director's office.

He didn't even knock on the door and just pushed it open and walked in.

Zhou Ming, who didn't know about this at the time, looked at who pushed open the door of his office with a puzzled look on his face.

When he saw it was Li Xuan, he immediately smiled and spoke.

"Hey, why are you back?"

"Come on, come on, sit down. I'm telling you my family just sent me some Pu'er tea. You're here."

While speaking, he was about to get up and get a cup to make tea for Li Xuan, completely unaware of Li Xuan's mood at the moment.

When he walked to the water dispenser, put tea leaves in it, and walked towards the sofa with the cup in his hand.

But he found Li Xuan standing at the door with red eyes looking at him silently.

Seeing this, Zhou Ming looked at Li Xuan at the door with a puzzled look on his face and asked with a teacup.

"Li Xuan, what's wrong?"

Upon hearing this, Li Xuan spoke solemnly to Zhou Ming, who looked puzzled.

"The master is gone."

Bang!

Zhou Ming was distracted when he heard this and the cup in his hand fell to the ground.

He walked up to Li Xuan in disbelief, grabbed his shoulders and asked softly.

"What did you say?"

Hearing this, Li Xuan could no longer hold back the tears in his eyes and sobbed as he spoke to Zhou Ming.

"Master...Master is gone."

Zhou Ming became furious upon hearing this and started talking.

"Don't talk nonsense! I just went to see the master the day before yesterday!"

"Did you take the wrong medicine today? Master is still in my jurisdiction!"

"How could I not know if he left!"

"Impossible! Absolutely impossible!"

Upon hearing this, Li Xuan handed the file in his hand to Zhou Ming who was shocked.

"I just got back from today's incident."

When Zhou Ming heard this, he hurried forward, snatched the file and started reading it.

When he saw his master Xu Guodong lying on the ground with more than ten knife wounds in his body.

He froze in place for a moment, tears streaming down his face. He was nearly fifty years old.
