Siheyuan came through and sent Jia Zhang to prison

Although Zhao Lei was full of doubts and had no idea why Li Ai was arrested, as a conscientious policeman, he knew that obeying the orders of his superiors was his duty. So, despite his doubts, he still acted according to the instructions issued by the director without hesitation.

At this time, He Feng stared at Zhang Sheng with a sharp gaze, and said earnestly: "Don't be afraid, I came to you just to ask some questions. I personally approved your employment at the beginning. Now tell me, who else was on duty last night besides you?"

You have to know that although Zhang Sheng is a highly educated talent, his family background is a bit bad. His parents are landlords and originally did not agree with him joining the Public Security Bureau. However, He Feng still believed that talents should not be discarded casually, so he agreed to let him join the Public Security Bureau.

After Zhang Sheng arrived, he also performed his duties conscientiously, but he did not expect such a thing to happen.

Zhang Sheng was bewildered, and was really confused about Gao Cheng's choice of suicide. He looked at He Feng tremblingly and answered carefully: "Director, besides me, there was only Sister Li Ai. She said she wanted to stay to sort out an important document, so she left a little later than the others."

He Feng nodded slightly, indicating that he understood the situation, and then asked: "So, during the whole night, did you notice anything unusual or strange?"

Zhang Sheng shook his head vigorously and responded firmly, "Absolutely not, Chief! Everything is the same as usual, nothing special."

However, He Feng did not completely believe that Li Ai could have committed the murder without Zhang Sheng noticing, unless... there was some hidden connection or collusion between the two.

Just as He Feng was thinking about something and preparing to ask further questions, Zhang Sheng suddenly seemed to remember something, and hurriedly looked at He Feng and said, "Director, there is such a thing. Last night, I don't know what happened, I suddenly felt an irresistible drowsiness, and then I fell asleep for more than an hour without knowing it. When I woke up, I was surprised to find that a lot of time had passed."

Hearing this, He Feng nodded again, indicating that he knew about this matter, and then instructed Zhang Sheng: "Okay, you go down first. Remember, don't tell anyone anything about what we talked about today."

Zhang Sheng looked at He Feng and said tremblingly: "Director, I will go back first."

He Feng nodded. Now the target was very clear. One of the traitors hiding in the Public Security Bureau was Li Ai.

So He Feng took out Li Ai's file again, but there was no problem on it. He Feng was not in a hurry. After all, as long as he had this clue, he could follow this clue and catch all the spies in one fell swoop.

When Zhao Lei arrived at Li Ai's house, Li Ai was resting and looked very weak. He was also drinking water continuously.

Li Ai didn't know why Zhao Lei suddenly came to her house. At this time, Li Ai seemed to have become unresponsive.

Li Ai opened the door for Zhao Lei: "Captain Zhao Lei, how come you have time to come to my house at this time? I am off duty today and don't have to go to work."

Zhao Lei was afraid that Li Ai would do something wrong if he provoked her, so he smiled kindly and said, "Sister Li, you don't know that Gao Cheng died in our prison, Zhang Sheng has been investigated, and all of you who were at work yesterday need to be investigated. Please come to us."

Li Ai panicked when she heard that she was going to be taken for investigation, but she felt relieved when she thought that everyone would be investigated.

After all, Li Ai knew that someone had died in the Public Security Bureau, so she naturally had to investigate. Moreover, she still had confidence in her own methods. Besides, there were people in the Public Security Bureau who could help her, so they would definitely not be able to find out anything.

But Li Ai didn't know that the people above had given up on her. Zhao Lei also noticed something was wrong with Li Ai: "Sister Li, let's go to the Public Security Bureau to do an investigation. Do you have a cold?"

Li Ai shook her head. In fact, Li Ai also felt that something was wrong. After all, she had not slept much since she came back last night, and she had been feeling very thirsty.

Li Ai poured herself a glass of water: "Captain Zhao, I may have come back a little late last night and caught a cold, so I feel thirsty."

Zhao Lei watched Li Ai finish drinking the water, and then took Li Ai to the Public Security Bureau. On the way, Li Ai was still a little thirsty, but she held it back.

After arriving at the Public Security Bureau, He Feng looked at Li Ai and felt something was wrong: "Captain Zhao, come here."

After hearing what He Feng said, Zhao Lei hurried over and said, "Director, I have captured Li Ai. We have found all the things Gao Cheng wrote. They record why Gao Cheng wanted to cooperate with them and what he did after the cooperation."

He Feng still trusted Zhao Lei's speed, and just pointed at Li Ai and said, "Does she have a cold? Why does she look so weak? Can she pull up a man?"

Zhao Lei shook her head and said that she didn't know either. He Feng said that he could interrogate her.

Then He Feng watched Zhao Lei interrogate Li Ai: "Li Ai, why did you kill Gao Cheng?"

This was He Feng's signal to Zhao Lei, indicating that Zhao Lei should ask directly. He Feng wanted to see whether Li Ai would confess all her accomplices after her identity was known by the people in the Public Security Bureau.

Who knew that when Li Ai looked at Zhao Lei, although she was very panicked, she still pretended to be calm. After all, Li Ai felt that what she had done was perfect.

Zhao Lei saw that Li Ai was still pretending to be confused, so he looked at Li Ai and said, "Okay, Gao Cheng has written down everything about your cooperation. If you don't believe me, you can read it yourself."

As he said that, he handed the paper to Li Ai. After reading the letter, Li Ai knew that he had indeed made a mistake yesterday. The white shirt was the evidence that it was written by Gao Cheng, but she had thought that he was Gao Cheng's. Alas, one misstep led to eternal regret.

Zhao Lei looked at Li Ai and said, "Why don't you confess now? Who is your superior? Who are your accomplices? Tell the truth."

Li Ai looked at Zhao Lei. Li Ai had always been afraid of death. He joined them for money. Now that he was caught, if he actively cooperated, he could still spend the money when he got out. "I said, but can you give me a glass of water? I'm thirsty now."

Zhao Lei nodded and asked someone to pour her a glass of water. Unexpectedly, after drinking the water, Li Ai fell off the chair and started foaming at the mouth.
