"Li Xiaolangjun, I'm going to trouble you again?" Zhang Wei said with a sad face.

"Got into trouble again?" Li Tao asked with a smile.

"That's right!"

"Tell me about it!"

……

One late autumn evening, Yujuan, the daughter of Luzhou blacksmith Zhang Jin, was strangled to death in bed by a scoundrel named Lu Si. After Zhang Wei's interrogation, Lu Si confessed to his evil deeds.

According to Lu Si's confession, he has long coveted Yujuan's beauty, and has been staring outside the Zhang family's courtyard, this night Zhang Jin went to the neighbor Tao Er's house to set up a knife handle, Lu Si expected that Yujuan was alone at home, so he sneaked in to do the best thing, Yujuan resisted violently, and Lu Si choked her neck......

There are all the evidence, and the murderer himself has already pleaded guilty, so Zhang Wei only needs to put Lu Si on death row, wait for the case to be reported to the criminal department, and behead him after approval. However, when he saw Yujuan's corpse, he suddenly frowned.

Zhang Jin lost his wife at an early age and made a living by striking iron. daughter Yujuan depends on him for her life. Yujuan has suffered from dizziness since she was a child, and she has been taking medicine all year round, but she was targeted by the scoundrel Lu Si when she went to the pharmacy to grab medicine.

The Zhang family is poor, but Liu Long noticed that the clothes on Yujuan's body are very new but very ordinary, but the shoes on her feet are Yunjin shoes that only Miss Dahu can afford, how can this be explained?

And as soon as he returned to the yamen with this question, Zhang Jin hurriedly ran in, knelt down in front of him, and said eagerly that when he scrubbed the blood on Yujuan's face just now, he found that this corpse was not Yujuan at all, but the clothes on her body were hers.

Who is this female corpse, and is Yujuan dead? If Yujuan has indeed been strangled to death by Lu Si, then who replaced her body? It seems that this seemingly clear case is not simple. In desperation, Zhang Wei had no choice but to ask Li Tao for help.

Li Tao accompanied Zhang Wei to interrogate Lu Si again.

Lu Si confessed that the person who was strangled to death by himself that night was indeed Yujuan, and he had not taken a fancy to her for a day or two, and he would never be mistaken.

"Are you sure you strangled her to death at the time?" Li Tao asked.

Lu Si cried and said, "I admit that I strangled her to death, but I can't figure it out, I just pinched her a few times, and she vomited blood and died." How can I have that much energy?"

Hearing this, Li Tao was even more puzzled.

This Lu Si is no more than five feet tall and has an obscene figure, if he is allowed to strangle a woman to death in a few strokes, and he will vomit blood, it is indeed not an easy task. Could it be that Yujuan is not dead at all, it is just her trick? But why did she do it?

At this moment, someone found another female corpse by the river on the outskirts of the city. And Zhang Jin recognized at a glance that this was his daughter Yujuan, and she was grief-stricken and fainted.

Zhang Wei ordered someone to carry Yujuan's body back to the county office, and after an examination, it was concluded that Yujuan was not strangled to death, but was poisoned by arsenic. What's going on here?

At the same time, the arrest quickly found that another female corpse was Liniang, the daughter of Zhao Manyu, a wealthy man in the county.

According to Zhao Manyu, Liniang disappeared two days ago, because Liniang usually likes to go out to play, so Zhao Manyu didn't think much about it, and he didn't expect to be killed. Another homicide.

Thinking of the exchange of Yujuan and Liniang's bodies, Li Tao felt that the murderers of these two murders were either one person or must be related. Lu Si's suspicion is getting smaller and smaller. Li Tao decided to start with this arsenic, and a group of officials took the order to go.

Soon, the official brought Zhu Bao, the owner of the Huichun Hall on the outskirts of Huayin County, to the county office.

Zhu Bao said that three days ago, a man named Lu Si bought half of the two taels of arsenic in the Rejuvenation Hall.

"Do you know Lu Si?" Li Tao asked.

"I don't know" Zhu Bao shook his head.

"Since you don't know each other, how do you know that Lu Si bought arsenic in your pharmacy?"

"There is a rule in our pharmacy that someone can't buy arsenic more than one or two at a time, and the buyer must leave his name, and my account book clearly says that Lu Si bought arsenic three days ago." Zhu Bao said and took out an account book from his arms.

Li Tao opened it and saw that Lu Si's name was indeed written on it.

The spearhead was pointed at Lu Si again.

"Then do you remember what that Lu Si looked like?" Zhu Bao shook his head and said he couldn't remember.

Li Tao took Zhu Bao to the prison and asked him to identify Lu Si, but Zhu Bao never recognized him.

However, Lu Si firmly denied that he had bought arsenic in Zhu Bao's store.

Soon two days passed, and there was no progress in the case. According to the law of the Tang Dynasty, as long as there is human and material evidence, the suspect does not admit that he killed someone, which is also a capital crime. Now no matter whether Yujuan was strangled to death or poisoned, the focus of suspicion is still on Lu Si, and it stands to reason that Lu Si will definitely die. However, Li Tao didn't do this, he didn't sleep all night, and suddenly Li Tao seemed to think of something and hurriedly went to find Zhang Wei.

Early the next morning, Zhu Bao suddenly hurried to the county yamen and shouted to see Zhang Wei.

But the officials kept him out of the yamen.

"I have something important to see your lord."

"No, Lord Zhang is not in good health today, and all the idle people are gone." Ya Gong said.

"I just remembered what Lu Si who bought arsenic looked like, not the one in prison."

Zhu Bao said eagerly.

The official didn't seem interested, and pushed him aside: "Your Excellency is ready to close the case and report it to the Criminal Department, so don't make trouble here."

Zhu Bao left very dissatisfied, and the official scolded "troublesome", turned around and entered the yamen.

Then Zhu Bao came twice more, but was blocked by the officials.

In the evening, Zhu Bao closed early, sat in the store and drank tea, when a knock suddenly sounded outside the door.

"It's closed and there's no business." He shouted, but there was no response outside the door, and the knock continued.

Zhu Bao impatiently opened the door, a knife was placed around his neck, and then a masked man walked in, closing the door with one hand.

"Y-What are you doing?" Zhu Bao was extremely frightened.

"You have too much to do, I'll send you to Hades tonight." The masked man said as he raised his knife and slashed it down with great force.

With a thud, the masked man's knife was knocked off. Li Tao, Zhang Wei and Pei Yue and a group of servants had already surrounded him.

The masked man was taken aback and had to be arrested.

Li Tao concluded that the murderer who bought arsenic, and even murdered Yujuan, was not Lu Si, but someone pretended to be in the name of Lu Si, so he asked Zhang Wei to order the official to go out of the city overnight to find Zhu Bao, so that he hypothetically remembered the appearance of the person who bought arsenic and deliberately did not let him enter the yamen, so that the person would definitely jump out and kill people.

Now this man has really taken the bait.
