In case of an accident, the City Defense Department specially formed several temporary fire dragon teams, scattered in the inner and outer cities of Chang'an to deal with emergencies at any time. Liu Yu also mobilized some of the new army outside the city to enter the city with military doctors. If a large-scale explosion caused casualties, or if there was a missing arm and a broken leg, medical assistance could be provided as soon as possible.

After everything was arranged, Liu Yu felt that he was taking the sirloin from the fire and was too risky. He couldn't help but think of the links to track down more clues.

The He family is just an inconspicuous family of officials in Chang'an City. Liu Yu didn't know much about it before. He wanted to find someone to check it first. At this time, a guard came to pass the message at the entrance of the lobby of Jingzhao Mansion, saying that the Ministry of Justice sent someone to accommodate a group of prisoners. Liu Yu remembered that he had greeted the Ministry of Justice in the morning and wanted to investigate the case. It was the right way to mobilize the Ministry of Justice to help. Liu Yu called the Ministry of Justice to let the Ministry of Justice come in.

Liu Yu was still thinking about the matter, so the Lang official sent by the Ministry of Justice brought a team of people into the lobby. As soon as he walked in, he nodded and bowed to Liu Yu, smiling charmingly as if he had seen his parents who had food and clothing.

"Sir, the student will pay you a favor."

Liu Yu frowned. In this world, only Su Yan called him master, and only Wang Hu, the playboy.

At this time, Wang Hu was wearing the first-class official uniform of the Ministry of Justice from the third-rank official uniform, and looked like a decent person. Originally, Wang Hu was transferred to the Ministry of Rites as an errand for several days, but Wang Hu was completely a novice and no one was in charge of the Ministry of Rites. After working for a few days, he ran back to the Ministry of Justice to serve as a servant. During this year, he was promoted from a sixth-rank official to a deputy minister like a rocket.

"Mr. Wang is really full of energy. Where has he made a fortune recently?"

Liu Yuyu said with a strange voice, and Wang Hu smiled shyly, but he didn't care. At this time, the officials of the Ministry of Justice behind Wang Hu came over to hand over the documents of some prisoners with the Clerk of Jingzhao Prefecture, and were about to take over them and be detained at the Ministry of Justice.

"It's not worth making money. It's just a mess under my father's hands. I'll just ask for any help from the teacher. I have no choice but to ask for any part of the students who can help."

Liu Yu smiled disdainfully and thought to himself that Mr. Wang was good at eating, drinking and having fun, so what else could he do? Liu Yu was right to think so. But Liu Yu thought again, maybe Wang Hu could really help.

"He Lin, do you recognize He Dingqi?"

"I know, why don't I know each other? We used to go to brothels... Hehe, sir, don't get me wrong. In fact, the students have not been there for a long time."

"I don't care wherever you go. Just tell me who He Lin is."

Wang Hu then felt relieved and said, "That boy He Lin is the most unreliable. He used the excuse of not bringing money to ask the student to invite him several times. Later, because of a girl from Cuiyuelou, the student had a quarrel with him. It is said that he secretly took over the girl as a foreign house. This boy is too unfaithful."

"Is that girl called Han Qi?"

When Wang Hu heard Liu Yu mention "Han Qi", his inappropriate expression on his face was slightly restrained, and he understood that Liu Yu was not asking casually.

"It's not Han Qi. Han Qi had just arrived at Cuiyue Tower at that time, and no one could see Han Qi. Even if he spent money, he couldn't stand it. The girl who was wrapped in He Lin was named Su Yuer. He Lin was fascinated by He Lin's mischievousness. The boy was also quite bad and obeyed the students. But that day he felt like he had taken the wrong medicine and had a quarrel with the student for Su Yuer. He also hurt a guest in Cuiyue Tower. Later, the He family spent money to settle the matter..."

Wang Hu said it very much, just like telling a story. In this story, He Lin is just a gentleman in the official family. After all, the He family cannot match the power and financial resources of the Wang family in Chang'an City, so it is also necessary for Wang Hu to be the leader of a group of young men. But He Lin's attitudes are in contrast, either he is fearless or he is really like Wang Hu said, taking the wrong medicine!

Liu Yu turned around and said to Sui Yi: "Take people to Cuiyue Tower. Regardless of whether you have been to the Sima Mansion banquet yesterday, you will be arrested and interrogated one by one, especially the madam and the one named Su Yuer..."

Because Han Qi, the leader of Cuiyue Tower, was involved in this matter yesterday. Cuiyue Tower was surrounded and guarded by the government since last night. The girls and guests in Cuiyue Tower were not allowed to come out. It was much more convenient for Sui Yi to take or tie up people when he went like this.

Sui Yi ordered all the people and went in a hurry. Seeing Liu Yu being cautious, Wang Hucai carefully turned his head and asked, "Sir, but that boy from the He family... has caused trouble?"

Liu Yu glanced at Wang Hu, sat on the chair and said, "Don't ask if you shouldn't."

Wang Hu sighed: "I just said that something happened to the boy named He sooner or later, and there was only a few dollars to mingle with those brothel girls who eat people and don't spit bones. It's so unreliable..."

Liu Yu looked at Wang Hu with doubts, thinking that Young Master Wang has changed his sexuality recently. He turned around and criticized his former confidants, or wanted to act in this scene so that Liu Yu, the "Mr.", could look up to him?

"Have you been to Cuiyue Tower recently?"

"I haven't been there, I've definitely never been there." Wang Hu said with a stern sentence, and then said a little annoyed, "Sir, I also know the one at the student's house... who, if I don't go home until night, I can break my legs. How dare I go?"

"What if that person in your family didn't go home in the military camp?"

"That way, hehe." Wang Hu smiled treacherously, "I just went to see it during the day and went home before going to the update. I didn't dare to stay outside for a long time. All the maids at home were her confidants, so I have to be careful."

Liu Yu smiled helplessly, and he understood that if Xu Caihua was at home, Wang Hu would go home honestly every night. If Xu Caihua had not returned in the military camp, he would have a dew-loving fun with those "confidants", but he would not spend the night in the brothel. Liu Yuxin said that Wang Hu had already taken the opportunity to guard against the tigress at home, which was quite scientific.

Liu Yu stopped talking nonsense to Wang Hu. Not long after, there was a loud footsteps in front of Jingzhao Mansion. Sui Yi and several yamen servants came back and reported in a hurry.

"The big thing is not good, the big thing is not good." Sui Yi shouted as if the sky had collapsed.

Liu Yu stood up and greeted him and said, "Speak slowly."

"I brought people to Cuiyue Tower. A few girls died in Cuiyue Tower. When I entered, the bodies were still hot. Obviously, I just died. The madam Liu brother-in-law and the Su Yuer who asked me to pay more attention were also dead."

"How did you die?"

"If you take poison, you may have been poisoned by someone. The death is so terrible, with seven holes bleeding, and the ferocious look of death seems to be filled with resentment. The coroner has already had an autopsy there. By the way, it is quite strange to find this on their bodies. Hurry up and take it to Brother Liu to see what possible tricks might be."

Sui Yi asked someone to open a small cloth bag, which contained several yellow paper bags stacked into triangle shapes. Some powder was exposed in the bag. Wang Hu wanted to go up and touch it, but Liu Yu opened his hand.

"Don't touch it, it may be toxic."

Wang Hu was shocked and quickly retracted his hand.

"What has been checked?" Liu Yu asked looking at Sui Yi.

"It may be fragrant powder or incense ash. Anyway, I don't know much about it. The dead people have it, but other girls don't have it. It may also be poison, but these paper bags have not been sealed. They don't seem to have eaten this poison."

Liu Yu got some "proof of guilt" but had no idea what it was. There was no laboratory now, so he could not find out what these powders were. Liu Yu guessed it was a poison or a psychedelic medicine, otherwise he could not explain the abnormal reactions of He Lin and Han Qi.

Liu Yuxin wanted to have a chemistry laboratory, so that he could determine the ingredients of the powder. When he thought of the laboratory, Liu Yu immediately thought of the old charlatan Wu You. After all, Wu You had refined pills, and in this day, only alchemists would have contact with these chemicals.

"Shuda, continue to investigate this case, Wang Hu, go to the palace with me." Liu Yu asked someone to leave with a cloth bag and go back to the palace to ask Wu You.

"Enter the palace?"

When Wang Hu heard this, his eyes lit up. Liu Yu was willing to take him into the palace. What a great honor. With his status as a third-rank official, the court discussions in the palace are not yet his part.

"Don't want to go?"

"Go, go..."

Wang Hu followed Liu Yu happily, and immediately felt that he had become a disciple of the emperor and was about to become successful at any time.

After entering the palace, Liu Yu went directly to Wu You's Astronomy Institute to meet. As soon as he entered the door, he almost collided with a short "thing". Liu Yu saw it clearly and found that his hands were the little stuttering Wu Shuo's arms.

"Don't you have eyes when walking?" Although Wu Shuo and Su Bi have a good relationship, Wang Hu did not recognize her. When Wang Hu saw her, he thought she was a little palace maid and shouted.

"He is not long!"

Wu Shuo let out a "hum!" sound, and he seemed to be holding something in his hand. He quickly went out and headed towards the inner court. Needless to say, she went to play with Qi'er again.

"Who is this? So arrogant?" Wang Hu asked with some questions.

"I'm a little charlatan. Be careful that she will give you a poison tonight..." Liu Yu said half-jokingly, but Wang Hu immediately thought of who he was, and was shocked again. In these days, people who know how to calculate divination in the Tianxiang Star are like half-immortals. Maybe they can really use the magic of witchcraft and hate victory, which is a person who cannot afford to be guilty.

When Liu Yu entered the Astronomy Institute, Wu You was still fiddling with things as usual. When Wu You saw Liu Yu bringing so many people to come, he was a little stunned. He thought Liu Yu was coming to seek punishment. After Liu Yu took out the ornaments from the woman who was poisoned by Cuiyue Tower and expressed his purpose, Wu You put down the things in his hand to welcome him.

"Where did you find it?" Wu You didn't seem to be afraid that these things would be poisonous. He picked up a paper bag with his hand and smelled it. He looked up at Liu Yu and asked.

"What is it in some women, or in a group of women?"

"It's nothing. They are all mixed with some herbs that calm the mind. They are not poisonous, nor are they medicines like Wushi San. However, these herbs are unique to the Miao family in Lingnan. How could they appear in Chang'an City?"
