Huh? I spilled a pot of soup, and Xu Yao found the evidence. Mo Xiaoqing stared with eyes wide open, not knowing what to say.

Xu Yao then began to explain, "Little one, you should remember that Liu Lixuan likes to wear a watch the most, and he always wears that watch no matter where he is, right?"

Mo Xiaoqing answered affirmatively, "Yes, I can be sure of that. He never takes off that watch.

If that's the case, then would he also be wearing the watch when he stabbed his sister with a knife?

Mo Xiaoqing suddenly realized, "Captain Xu means that there is a high possibility that there is still blood of Liu Lidan left in Liu Lixuan's watch. Even if there is blood on the watch strap, Liu Lixuan himself will not realize it."

Xu Yao said more excitedly, "If nothing unexpected happens, we will get another clue. Liu Lidan, the toxins in the online bet are the same biological toxins, and this toxin needs to be mixed in the laboratory.

Liu Lixuan once studied in the UK, and maybe he met a very powerful biologist during his study abroad.

He brought back this toxin, and since he needs to mix it, and Liu Lixuan has always liked to wear this watch, then the toxin is also likely to penetrate into the metal strap.

When Mo Xiaoqing heard this, she jumped excitedly, "Captain Xu is indeed a tough detective. With these clues, we can completely prevent Liu Lixuan from leaving the country."

Xu Yao quickly rushed out of the office, took three criminal police officers with great kung fu skills, and went directly to arrest Liu Lixuan.

At this time, it was already 2:40 in the afternoon, and Liu Lixuan's flight was at 3:20.

Xu Yao had no choice but to turn on the police lights, increase the speed, and overtake all the way to the airport.

Time was running out. After parking the car in the airport parking lot, Xu Yao led a group of criminal police officers and rushed to the airport waiting room like an arrow.

Everyone anxiously scanned the crowd with their eyes, looking for Liu Lixuan's figure. Xu Yao also called Mo Xiaoqing and asked her to contact the person in charge of this flight and stop him when Liu Lixuan passed the checkpoint.

Five minutes later, the time was 3:15 and the plane was about to take off.

At the last moment, a criminal police officer suddenly shouted loudly, "The target has been found! The target person is queuing at window No. 3 to board the plane."

Xu Yao rushed over and walked into the crowd. After measuring his police ID, he said directly, "Liu Lixuan, I think your half of the flight must be cancelled. We want you to go to the police station."

Liu Lixuan was carrying a black handbag in his hand and dragging large and small bags behind him.

At this moment his face suddenly changed, "Comrade police, I am going abroad to discuss an important business. If you still want to find out any information from me, wait until I return home.

And you have no evidence to prove that I have committed a crime, you have no right to detain me. I will call my lawyer now."

Xu Yao snatched Liu Lixuan's phone, "No need to call. When you arrive at the police station, you can hire as many lawyers as you want.

And I can guarantee that once you enter the police station this time, don't even think about getting out."

As Xu Yao spoke, he leaned close to Liu Lixuan's ear and whispered, "Because you know better than anyone else that you are the real murderer."

From Xu Yao's confident and indifferent attitude, Liu Lixuan guessed that the police might really have found clues.

But he was still not afraid, because he firmly believed that everything he did was flawless and flawless.

Even when he was locked up in the interrogation room of the criminal police team, he was still calm and relaxed.

Xu Yao didn't say anything, but just asked him to take off the watch on his hand and let him wait here in peace.

Liu Lixuan angrily took off his watch and threw it to Xu Yao, threateningly: "My lawyer said that you police can detain me unconditionally for a maximum of 48 hours. If it exceeds this time, I can sue you.

And I can use public opinion to show the incompetence and abuse of power of your police."

Xu Yao smiled calmly, "Don't worry, we don't need 48 hours to make you lose your freedom forever.

Oh! By the way, for a scum like you who hurt your own sister, the death penalty should be more suitable for you."

After Xu Yao came out of the interrogation room, he ran into the angry He Shenming.

Deputy Director He shouted with a gloomy face, "Xu Yao, come to my office right now!"

As soon as Xu Yao entered, He Shenming threw the newspaper in his face, "Xu Yao, look at what you have done. Now everyone is talking about the Criminal Police Team.

Look at today's current affairs news. All major media websites have published it as the front-page headline. Liu Lixuan's brother was taken away from the airport...

Do you know what it says? It says that our police can't find the murderer, but now they are under pressure and are looking for a scapegoat."

Xu Yao didn't need to look closely, he knew that the person who could create such a huge public opinion effect was none other than Liu Lixuan.

Before Xu Yao could speak, He Shenming knocked on the wooden table and said, "Xu Yao, I really don't understand. This case could have been settled long ago. Haven't you already caught a murderer named Liu Yuemei? Why haven't you filed a case yet?

Now you tell me that Liu Lixuan is the murderer. Are you kidding me?

" "Where's the evidence?"

Xu Yao finally got a chance to speak, "Master, we just have to wait for the watch report to come out."

"Oh, you mean you can conclude that Liu Lixuan is the murderer just by looking at a watch. Are you playing house?" He Shenming's voice became louder and louder.

This was also the pressure from the leaders above, and Xu Yao could understand it.

"Master, please believe in the apprentice you brought up."

"No!" He Shenming said, "I can't let you do whatever you want. Do you know how much public pressure there is on Liu Lidan's death? All major media outlets are reporting on this matter all the time.

If we can't prove Liu Lixuan's crime, and Liu Lidan's only relative is mistakenly identified as the murderer by our police, do you know what we will face then?"

Xu Yao was silent for a while, and placed his pistol and police ID in front of He Shenming.

"Master, I won't make things difficult for you. I will bear the consequences of this matter alone.

I will use my police badge as a guarantee. If Liu Lixuan's watchband does not contain the evidence I need, I will resign."

After listening to this, He Shenming stared at Xu Yao for a long time with wide eyes, then shook his head with a sigh,

"Okay, you are capable! You said it."
