Xu Yao rubbed his temples again. Now, if he thought for a moment, his head would ache like it was about to explode.

In order to relieve the pain, he couldn't help but take out a cigarette from his pocket and light it. A cloud of mist swirled around him, and he immediately felt much better.

However, Mo Xiaoqing, who was standing by, coughed loudly due to the secondhand smoke. She couldn't help but frowned and said,

"Captain Xu, do you know that the nicotine in a cigarette can kill a mouse?

Smoking is really bad for your health, so it's best not to smoke."

Xu Yao took another deep puff, blew out three or four smoke rings, and deliberately sprayed eggs on Mo Xiaoqing's face.

"Then do you know that only his wife or girlfriend can control a man's smoking, and the assistant does not have this right."

After he explained this, Mo Xiaoqing felt embarrassed again.

"I'm sorry, Captain Xu, I don't mean anything else. I just think smoking is harmful to health."

Xu Yao smiled brightly, "If you want to have this right, I can actually consider it."

Mo Xiaoqing didn't want to hear Xu Yao's joke, so she changed the subject back to the case.

"Captain Xu, I really think that Madam Liu is the biggest suspect."

"I think so too. Liu Yuemei is Huang Yousheng's legal wife, and she married him when Huang Yousheng was very poor. Who would have known that her husband did not treat him well after he became rich, and actually kept a mistress outside for five years.

A person's tolerance is limited. From a psychological perspective, a person's hatred will accumulate more and more, and when it reaches a critical point, it will explode."

Mo Xiaoqing said with sudden enlightenment: "Then Liu Lidan's entanglement with her husband again is that critical point."

"That's right. You should still remember that our police found a murder weapon with Huang Yousheng's fingerprints on it, but don't you think it's strange?

When Huang Yousheng entered Liu Lidan's villa, he actually wanted to kill Liu Lidan, so after dinner, he wiped off all his fingerprints.

Huang Yousheng is so cautious that he couldn't be so careless as not to wipe off the fingerprints on the murder weapon and carelessly throw the fruit knife into the most conspicuous trash can at the gate of the villa."

Mo Xiaoqing's eyes lit up and she exclaimed loudly, "Oh, this is a frame-up. The real murderer killed Liu Lidan with a fruit knife that had Huang Yousheng's fingerprints printed on it in advance. When she came out after killing her, she was afraid that the police would not be able to find this clue, so she deliberately threw the knife in the most conspicuous place."

"Yes, think about it, who could have so easily obtained the fruit knife with Huang Yousheng's fingerprints, when he is always protected by three bodyguards?"

Mo Xiaoqing immediately answered, "I'm afraid only Mrs. Liu, who lives with Huang Yousheng, could do this."

Xu Yao said, "It depends on whether our inference is correct. We have to wait for the samples of Mrs. Liu's nail polish to be sent from Longhai City before we can decide."

But Mo Xiaoqing was like a curious baby and couldn't help asking, "Captain Xu, didn't you say there were two murderers at the scene? Besides Liu Yuemei, who else hated Liu Lidan so much that he stabbed her five times even though she was already dead!

Who would this person be ?" Did they steal money at the same time?"

Xu Yao pondered for a while and said, "This possibility cannot be ruled out. The five knives that stabbed Liu Lidan's back obviously caused different injuries than the two knives that stabbed her in the abdomen. We can rule out that the same person committed the crime. No one would change a knife during the murder process.

Liu Lidan is already dead, but he still wants to vent his (her) anger on the corpse, which shows that he (she) hates Liu Lidan very much."

Mo Xiaoqing interrupted, "Captain Xu, didn't we investigate the threat case of Liu Lidan last time? Didn't we catch a crazy fan at that time? Could he come back again and commit another crime in Liu Lidan's villa?"

"It's basically impossible. No matter how powerful the crazy fan is, he shouldn't be able to enter Liu Lidan's private villa.

It can only be someone close to Liu Lidan. But when you said that, it reminded me of the clue we have been ignoring, that is, the other threat actor in the threat case, whom we have not tracked down. My

intuition tells me that it is very likely that this person has a great relationship with Liu Lidan's death."

Mo Xiaoqing couldn't help but feel admiration in her heart. Captain Xu's analytical thinking was indeed very clear.

"But Captain Xu, if we can prove that Liu Yuemei stabbed Liu Lidan with two knives in the abdomen, the man who stabbed Liu Lidan five times, even if he is caught, can only be convicted of insulting a corpse at most.

After all, the person is already dead."

Xu Yao didn't think so, and always felt that this case was too simple. But in real life, not every murder case is as complicated as in detective novels.

The discussion and speculation of the case was almost over. Due to the lack of strong evidence, and it was already 5 pm, Xu Yao suggested that Mo Xiaoqing go to the cafeteria with him to eat and think freely.

But suddenly, Mo Xiaoqing's cell phone rang, and she picked it up and found that it was Li Tianfeng calling.

"Hello, Officer Mo, are you busy now?"

Mo Xiaoqing answered simply, "Oh, I just finished."

"Well, I just came to your criminal police team to deliver some information. How about we have dinner together?"

Mo Xiaoqing stood there, not knowing how to answer. She had just agreed to go to the cafeteria to eat with Captain Xu.

Xu Yao heard everything that happened on Mo Xiaoqing's phone. He patted her shoulder and made a gesture, which meant "You go, I'll go to the cafeteria alone."

With Captain Xu's approval, Mo Xiaoqing couldn't refuse, because Li Tianfeng's reason that he couldn't refuse was ringing on her phone.

"Officer Mo, I must have helped you many times, but you haven't taken the initiative to treat me to a meal."

Mo Xiaoqing pursed her lips, "Okay, I'll treat you this time."

Xu Yao, who had already opened the door of the conference room and walked out first, was very annoyed in his heart, even though he was rushing forward. He wanted to turn around and stop Mo Xiaoqing.

He wanted to tell Mo Xiaoqing his deepest thoughts: I don't like you eating with other men. You are not allowed to go!

But he only thought about such overbearing words in his heart, and did not speak them out loud. Instead, he chose to go to the cafeteria alone.

Although it was the same meal and the same seat today, Xu Yao felt that today's meal was inedible and extremely unpalatable.

Xu Yao threw down his chopsticks after just two bites and started smoking, one after another.

When he was about to smoke the fifth cigarette, an arm suddenly stretched out and snatched the cigarette from his mouth.

"Xu Yao, if you want to live a few more years, you must treat yourself as a human being."
