Last time, the grandfather and grandson fell into Yunbei's drug, and this time he fell into the trap again.

Yun Bei didn't care what Rong Rui thought. She believed in a saying: no matter whether it is a white cat or a black cat, as long as it can catch mice, it is a good cat.

It is also said that skills are not afraid of being old, as long as they are useful.

Look, isn’t Rong Rui fascinated now?

Looking at Rong Rui lying on the ground, Si Nanzhao and Yun Bei looked at each other and breathed a sigh of relief at the same time.

Rong Rui's skills were quite good, and although the two of them could definitely defeat him together, it would take some time, so it would be better to just knock him out directly like this.

"Wife, this man has fainted. Should we send him to the police station now? Let's wait until tomorrow."

After thinking for a moment, Yun Bei said, "Let's talk about it tomorrow. Let's lock him up in the space first."

I guess there are only people on duty in the police station at this late hour. Forget it, I'll just go to sleep first.

"Okay, I'll do as you say. But I have to tie him up first."

"Okay!" Si Nanzhao found a rope, tied up Rong Rui, and brought him into the space.

In order to prevent Rong Rui from waking up in the middle of the night, Yun Bei gave Rong Rui a few injections to make him sleep more deeply.

But today is destined to be a sleepless night.

Not long after the two returned to the space, someone knocked on the gate.

Yunbei and Sinanzhao had no choice but to come out of the space again, then open the gate to see who was knocking on the door so late at night.

When they saw that it was Zhou Yanfang who came, they immediately knew that something must have happened, and couldn't help but ask: "Yanfang, what happened?"

"Nan Zhao, sister-in-law, the man we arrested committed suicide in prison."

"He committed suicide?" Yun Bei was shocked and asked, "How did he die?"

"Nothing can be seen. There was no sound, and no wounds were found on the body. So, I would like you to go over and take a look at what is going on."

"Okay, let me change my clothes and then go with you."

Yunbei and Sinanzhao returned to the room, discussed it, and decided to take Rongrui directly there.

Previously, the two wanted Rong Rui to stay in the space for a night because they were worried that there would be no one at the police station. Now that Old Man Rong was in trouble, there must be a lot of people at the police station.

Zhou Yanfang was waiting outside, but when he saw Yun Bei and Si Nanzhao bringing someone out, he was stunned.

After a closer look, they found that it was Rong Rui, the man they were looking for. They were immediately surprised and delighted, and asked, "Nan Zhao, sister-in-law, how did you catch him?"

"He walked into the trap himself." Yunbei smiled and didn't say much.

But Zhou Yanfang automatically supplemented his brain. He thought that Yunbei and Sinanzhao had known that Rong Rui would come to seek revenge on them, so they set a trap early and waited for Rong Rui to fall into it.

Therefore, I admired them deeply and asked, "How did you know he would come?"

"I guessed it." Yun Bei smiled, then handed Rong Rui to Zhou Yanfang and said, "He's been drugged and won't wake up for a while."

After hearing this, Zhou Yanfang gave Yun Bei a thumbs up and praised: "Sister-in-law, you are really amazing."

Yunbei smiled and said nothing. However, she did not think she was that great, but only felt that she and the Rong family might not be compatible.

Otherwise, why would they fail in their own hands again and again?

To be honest, if the two of them had escaped and lived in hiding, no one would have known they were still alive and no one would have been able to find them.

But they chose to take revenge, so naturally, the law is vast and nothing can escape it. It is only a matter of time before they are caught again.

The people at the police station were all impressed when they saw that Zhou Yanfang had just gone out to look for someone and brought back the person they wanted to arrest.

"Yan Fang, you are too amazing, aren't you? We have been looking for the person for a long time and couldn't find him, but you actually caught him."

"Yeah, Yan Fang, do you have any secret? Otherwise, how come so many of us went out and didn't even catch a hair, but you just went out and captured the person like that."

Seeing their talk getting more and more outrageous, Zhou Yanfang immediately interrupted them, saying, "This isn't my work. It was Nan Zhao and my sister-in-law who caught him. Didn't you see he's still unconscious? I'm telling you, my sister-in-law drugged him."

"Really? Sister-in-law is really amazing, isn't she?" Everyone looked towards Yunbei as they spoke. They were envious that such a huge achievement fell on her and Si Nanzhao.

Catching the escaped traitor is a great achievement, and promotion and salary increase are definitely a given.

"Don't praise me, everyone. This is just a coincidence. If you're talking about being amazing, I can't compare to you guys."

"Alright, everyone, make way. I'll take him away and lock him up. We'll have to go and see how the old man died later. Otherwise, when the leader asks about it, we won't know what to say."

After hearing what Zhou Yanfang said, everyone immediately made way.

Zhou Yanfang locked Rong Rui in the cell and asked someone to guard the cell door. Then he took Yun Bei and Si Nanzhao to another cell.

In the cell, old man Rong lay quietly on the ground, no longer alive.

Yunbei walked forward and checked Old Man Rong's whole body. He found no external injuries on his body. He then looked at his eyelids and mouth and confirmed that he died of poisoning.

She told Zhou Yanfang her conclusion, which surprised him. He said, "He died of poisoning. Where did the poison come from? There are people watching over this cell, and he didn't have any contact with outsiders."

"It is also possible that he brought the poison himself." Yun Bei knew what Zhou Yanfang suspected, but she felt that at this critical moment, those people would definitely not dare to make any move.

Because once discovered, it would be the end of him. Therefore, she was more inclined to believe that Old Man Rong had brought the poison himself, just like her, he often carried some small self-defense items with him.

For Old Man Rong, this poison was not only his self-defense, but also his weapon. However, this time, the weapon was aimed at himself.

"If that's the case, then he should have poison on him. Let's look carefully and see if we can find anything."

"Then let's look for it." Yun Bei did not object and started looking for it together with Zhou Yanfang.

Soon, the two found residual poison on Old Man Rong's collar.

He hid the poison in his collar, no wonder they didn't find it.

It turned out that before Old Man Rong was caught and put in jail, he was searched.

However, they did not find any poison on him during the body search, which is why they had not thought about it in this direction.

They had always suspected that Old Man Rong was murdered, but they could not find any evidence of murder, so they had no choice but to ask Yunbei for help.

Because Yunbei is a doctor, she understands the human body better than they do.

Now it seems that it was the right decision to look for Yunbei.
