"First, the main contradiction between the two is indeed around gift money. The younger brother wants to ask her husband for all gift money to repay the debt. The husband has sufficient reason to refuse this younger brother, but he seems to have a handle on his brother."

"handle?"

"Well, I don't know what it is. During the conversation between the two, they always used 'that thing'. That thing not only threatened the husband, but also involved a lot of money.

My husband was very tough, but he had already spoken and would not give a penny to his younger brother.

However, when the younger brother mentioned that matter, he hesitated. In the end, he not only promised to give all the 60,000 yuan gift money to his younger brother, but also promised to give all the large amount of money related to the matter to his younger brother. Not only that, but also..." Yan Ruyu frowned and shook his head, "I really can't understand."

"What's wrong? What's wrong?"

"I also promised to give my brother 3,000 yuan a month to live in the future."

"What?!" Wu Cuo also widened his eyes in surprise, "How can this happen? When his sister dies, he has a relationship with his brother-in-law! Why should he raise him? Vampire! It's simply an unequal treaty!"

"Yes, so I'm very curious, what kind of handle does this brother have mastered? It can make his brother-in-law give in to such a level."

"Can it be... illegal?" Wu Chou said.

"Then I'll just tell you all. According to the makeup artist at the funeral home, Li Xiuxia's body was blue all over... So, the question now is, do you want to continue pursuing it?" Yan Ruyu said.

"You're blue all over? Do you mean... poisoning?" Wu Cuo asked.

Yan Ruyu took out two evidence bags from his pocket, one of which contained a needle and the other containing gauze with very fast blood stains.

"The body has been burned. This needle was obtained from the makeup artist. It has sewed the wound on Li Xiuxia's head. As for the gauze, it has cleaned up the blood on Li Xiuxia's head."

Wu Cuo took the evidence bag and looked carefully. He could see that there was vague skin tissue at the tip of the needle. "If you have good luck, independent inspection should have results.

Investigate! When it comes to human lives, of course we need to investigate! But..." Wu chou glanced at the small banquet hall, "I think it's better not to let Zhou Tian know."

"I think so too," Yan Ruyu agreed deeply, "It just so happens that she now believes that Li Xiuxia's death has no doubts. We just need to finish our meal and send her home, and we will complete the task."

"Yes, it's better not to carry this tail in the subsequent investigation."

"Hey, you two, what are you doing?"

The two of them turned around suddenly as if they were electrocuted, and happened to see Zhou Tian's suspicious gaze.

"We...uh...wait for the toilet!"

"smoke!"

The answer to the strange voice is even more suspicious.

"The one who is waiting for the toilet is to smoke a cigarette first." Yan Ruyu hurriedly explained.

Zhou Tian circled around the two of them, looking up and down while turning, and from time to time he leaned over his nose to smell it.

"Why did I smell a conspiracy? I heard it all, and said! Are you carrying me on your back..."

The two looked at each other, their hearts twitching. Except for Minghui, every cell in their bodies refused to take the woman to investigate the case.

"Hmph! You must be making fun of me behind my back!"

"ah?--"

"ha?--"

As soon as Zhou Tian said this, the two almost swear.

Yan Ruyu reacted quickly, and he leaned on Wu Cuo and said embarrassedly: "You discovered it."

"Hold the grass! Hold the grass! Hold the grass!" This is Wu Cuo's real psychological reaction at this moment. He only felt that Yan Ruyu was almost dissatisfied when he was so deliberately connected to each other. However, he had to cooperate with Yan Ruyu and look calm.

"I'll eat, you guys continue, I'll take a taxi back by myself, no need to deliver it."

Just after the anniversary, Yan Ruyu scattered Wu Cuo, and ran to the bathroom in two steps at a time. He lay on the sink and started to retching.

Wu Cuo followed closely, "Aren't you? Just hug me and... are pregnant?"

"Go to your uncle!" Yan Ruyu glared at him through the mirror, "I'm so disgusting myself."

"puff……"

A day later, Yan Ruyu, who was playing games in the unsolved case archive room, received a call from Wu Cuo.

"The toxicological test results are out, come down and see it quickly."

...

"The blood on the gauze did not detect toxicological reactions, but the sample extracted from the suture needle showed that penicillin allergies were found."

"Penicillin is allergic? Shouldn't this drug be tested first before using it?" Yan Ruyu said.

Wu Cuo rubbed his forehead, "Do you understand the point?"

Yan Ruyu spread her hands and expressed her confusion.

"The key point is, why does the blood on the gauze have no toxicological reaction, and penicillin allergicity is found on the suture needle? Why do the test results of the test materials extracted from the same person are different?"

"It's very simple," Yan Ruyu looked at Wu Cuo's head and sighed, "IQ, IQ."

Li Xiuxia was bleeding from the head injury. The doctor should stop the bleeding first, then clean the wound, and finally give it antibiotics and tetanus drugs to prevent the wound from getting inflamed and infected, right?"

"In theory, that's the case." Wu Cuo nodded.

"That's easy to understand. The blood wiped on the gauze was flowing out of the wound before penicillin was injected, so of course, the allergic reaction of penicillin cannot be detected."

Wu Cuo patted his head with some annoyance. This is indeed a simple question. You should think about it more and you can't ask questions any more. He reminded himself in his heart.

Yan Ruyu continued, "Hey, by the way, where did Li Xiuxia die? Or a mental hospital at home?"

"It's a mental hospital. Xiao Jinzi checked the funeral home's departure records and her body was pulled from the mental hospital."

Yan Ruyu nodded and said, "In other words, the mental hospital is likely to be where Li Xiuxia was injured, received treatment, and finally had a medical accident."

"It's indeed necessary to go there first." Wu Cuo said.

"Team leader! Xiaobai and I were so bored that we were almost growing in moss!" Minghui came forward and said.

Xiaobai also said: "Yes, team leader, take us with you!"

"We are not afraid of being light bulbs!" After saying this, Minghui realized that he had made up his words, fearing that Yan Ruyu and Wu Cuo would not take him, so he quickly said, "I mean... um... Conan's physique like you who can encounter murders when traveling or having sex with you... I am really out of reach..."

Xiaobai secretly took pictures of Minghui and sighed: "It seems... it gets darker and darker the more I draw it..."

"Ahem," Wu Cuo went out, "Who was going to solve the case, why don't you keep up with me."

Yan Ruyu also shook her head and went out, "Why don't you forget it? What about solving the case but not solving the case? Anyway, the world has been controlled by the fujokovic, and we will soon be defeated by the tyranny of the fujokovic."

"Hold the grass! Old Yan, can you stop being so disgusting!"

Beijing Beishi Mental Hospital.

As a criminal policeman, he always encounters a few suspects who pretend to be crazy and stupid every year. Of course, there are also many criminals who do have mental problems. Therefore, Wu Cuo has met several psychiatrists, but this is his first time in a mental hospital.

Unlike his imagination, there was no gloomy atmosphere, nor the screams and roars of mentally ill patients in horror movies. Even, perhaps because of the warm lights, Wu Cuo even felt that the place was decorated quite warmly.

A doctor who was quite familiar with Wu Chou received them.

"I am very foreseeable, Officer Wu, without official documents, I am afraid I cannot provide you with patient information."
