"Then it depends on who poisoned it and how it was poisoned."

As Zhang Jin spoke, he took out a new pair of playing cards from his pocket. After opening them, he took out the top big and small kings and smeared all four sides of the playing cards with snake venom. After doing this, he mixed the snake venom with the remaining playing cards.

Call them all Li Jie.

"You take the things, I'm going to go in and do some work now."

"Is this possible? You use playing cards to kill people?" Li Jie looked disbelieving.

"Wait and see!" Zhang Jin got on his motorcycle and drove towards the police station opposite.

After parking the car, he put on his police ID and walked towards the office of the Criminal Investigation Department upstairs. When he arrived at the door of the department, he happened to bump into Rachel Zheng coming out.

Zheng Ruiqiu greeted him and said, "Zhang Jin, come and see Sir An. He is having a meeting with Brother 1 and other departments upstairs."

"Don't worry, the doctor's interrogation went well, right?" Zhang Jin said.

Zheng Rachel Qiu said: "It's okay. The doctor refused to say anything at first. Later, after his lawyer came, he told everything. But he actually put all the blame on his brother. It's so shameless!"

"You have worked hard these past few days. I see you have dark circles under your eyes. Go and take a rest."

"I would like to rest, but things haven't been finished yet. I can't go to the front line like you, so I can only help from behind." Zheng Rachel Qiu said with a smile, "I will sort out the information first, you can do it yourself."

"I want to see which interrogation room the doctor is being held in."

"Oh, he was temporarily detained in the medical room because of his leg injury."

Zhang Jin said goodbye to Zheng Rachel and walked directly to the medical room upstairs without entering the department. When he arrived at the medical room, he saw two uniformed policemen guarding the door.

"Brothers, I am Zhang Jin from the criminal investigation department. Who is the prisoner talking to?" Zhang Jin walked over and took a look through the glass window at the door.

The uniformed police officer checked his ID and replied: "He has been talking to his lawyer for almost an hour."

Zhang Jin thought for a moment, then turned around and went to the vending machine next to him to buy two cans of coffee and gave them to the two uniformed policemen. He held a can of Coke and said, "Thank you for your hard work."

"Thank you sir Zhang."

"I heard that the doctor was captured by Sir Zhang. It was broadcast on TV. He broke into the thief camp single-handedly. It's really awesome!"

After the two uniformed policemen took the coffee, they started talking more.

The three of them started chatting at the door. Zhang Jin took the opportunity to observe the situation inside, and soon came up with an assassination plan.

Not long after, the lawyer inside finished the conversation and walked out of the room.

Zhang Jin took advantage of the gap between the two military uniforms to inspect the lawyer's body and briefcase, and before the door closed automatically, his eyes were fixed on the doctor's neck.

The doctor also saw Zhang Jin, but the look in his eyes suddenly made him feel very uneasy.

Two seconds.

The door has automatically closed halfway.

At this moment, Zhang Jin suddenly took action!

Using the cover of his body, he took out a playing card from the pocket of his windbreaker with his right hand and clasped it between his fingers. With a flick of his arm, a swirling black shadow shot through the crack in the door towards the doctor on the hospital bed, scratching his neck.

There was a wound that was enough to break the blood vessels in the skin, and then it flew out of the window unabated.

"Uh..." The doctor covered his neck, pointed at the door and was about to shout for help, but a feeling of paralysis prevented him from opening his mouth.

Click!

The door closes automatically.

Zhang Jin was leaning against the wall next to the door, drinking Coke without a sip, as if nothing had happened, and his eyes fell on the lawyer.

"The inspection is over."

"Then can I leave?" The lawyer took back his things and left without looking back.

"You guys talk first, I'll go talk to the lawyer." Zhang Jin said to the two uniformed policemen.

Zhang Jin followed the lawyer into the elevator, and the lawyer glanced at him: "Is there something wrong with this sir?"

"It's okay, I just took the elevator downstairs." Zhang Jin said calmly while drinking Coke.

Ding!

The elevator quickly arrived downstairs. As soon as the elevator door opened, the lawyer walked out of the door and before he had time to react, he was immediately put down to the ground by the police who had been waiting outside the door and handcuffed.

"Stop! Let go! Do you know what you are doing? I can file a complaint against you for treating a lawyer so rudely..." the lawyer yelled.

"Lawyer Qian, right? I now suspect that you are suspected of murdering the criminal doctor who was the mastermind of the jewelry robbery at the Cointreau Hotel. Please come back with us to assist in the investigation." The team was led by another inspector from the same department.

After the captain of the inspection team said these words, he turned to look at Zhang Jin, and then led the person into the elevator.

Zhang Jin walked out of the elevator with a calm expression, walked to a trash can and threw the finished Coke can into it while the other party watched.

The elevator door closed, and he looked back for a while before walking out of the door. Although the playing cards flew out of the window, he still had to get rid of them for safety reasons.

If the playing cards were discovered, he would probably be suspected. After all, Jin Shixin had witnessed his own flying card skills when he was in Kowloon Walled City.

Zhang Jin found the bloody playing card in the garden downstairs behind the police station. After making sure that no one was paying attention, he walked over and took the playing card away, and went to the toilet on the first floor to burn the two playing cards with a lighter.

Burn it to ashes and flush it all down the toilet.

In fact, he has completed his mission whether he kills the doctor or not. He only kills the doctor to fulfill his promise to Li Jie.

As soon as he finished all this, the BB phone in his hand rang, and it showed that Sir An asked him to return to the department immediately for a meeting.

The reaction was really fast, but I didn't leave any traces at all. It was definitely no worse than my own head.

The surveillance at the Police Headquarters these days is not as strict as in later generations. It is usually only installed at key entrances and important departments. There are no surveillance cameras outside the medical room, which is why he dared to take action directly.

Zhang Jin washed his hands and face to clean off the smell of fireworks, then walked out of the bathroom and took the elevator upstairs.

When he arrived at the Criminal Investigation Department, he found that the atmosphere inside was very solemn. Although everyone was busy as usual, the expressions on everyone's faces were not as relaxed as before.

Zheng Rachel Qiu saw him coming, so she went up to him and said, "Sir An is waiting for you in the conference room."

"Just wait for me?" Zhang Jin was a little surprised.

"You are the last person to see Lawyer Qian and Doctor Qian. They should ask you routine questions. In addition to you, there are also the two colleagues guarding the door of the medical room." Zheng Rachel Qiu said.

Zhang Jin nodded, came to the door of the conference room, knocked on the door and walked in.

"Hello, Sir An! Hello, colleagues!"

Sir An pointed to the empty seat and said: "Sit down, I think you should also know the news about the doctor's death. As the last person to see the doctor, please tell everyone what happened just now."

"good."

Zhang Jin looked around the people in the conference room and calmly recounted what had happened before. Except for the incident of him killing the doctor, everything else was hidden in detail.

After listening to his story, everyone listened to the stories of two uniformed policemen. From the stories of the three people, it was known that except for Lawyer Qian, no one else had ever entered the medical room and contacted the doctor, so Lawyer Qian was the only suspect.
