Wei Yan asked Liu Zhang to write the gunpowder formula, and he dedicated it to Liu Che tomorrow.

Such a good thing, the sooner it is studied, the better, it will be of great help to the Han army.

Liu Zhang had already prepared the recipe, and Liu Che had seen the fireworks bloom in the Honghou Mansion.

He didn't ask for a gunpowder formula, and he felt that he wouldn't need it in a short time.

Liu Zhang gave a paper scroll to Wei Yan and asked him to hand it to Liu Che.

If you want to increase the power of gunpowder, let others study it.

Liu Zhang still wants to live a few more years, and he also wants to keep a low profile.

After the fireworks were over, Liu Zhang gave them some small gifts.

They left happily, and the next month, they invited Liu Zhang to their banquet.

Liu Zhang suggested that everyone meet again next month, if he often went to other people's homes for banquets.

It was really tiring, and he had other things to do.

The mansion soon fell silent, and the others left one after another.

They came to visit Liu Zhang today to celebrate him.

Everyone made friends with each other, which was a common phenomenon in aristocratic circles.

I talked to Chen Yun for a long time, and when she was tired, she fell asleep.

Early the next morning, there was a news in Chang'an City.

She woke up, she left the room and walked around, she was in a better mood today.

Last night, Zhao Ci examined her body and prescribed her a calming medicine.

And comforted her to try not to think about the misfortunes that befell her, and the happiness of the future awaited her.

"Have you heard? There was a murder outside the city, and several people were tied up like rice dumplings. Hanging from a tree, and not wearing a single piece of clothing. ”

She listened to the maidservants in the house whispering, and she guessed that those people were the ones who bullied her.

They had been killed, and they had died horribly, and she felt that Liu Zhang had done it.

If this is the case, it can be regarded as avenging him, and she is very grateful to Liu Zhang for avenging her.

But in this way, the Chang'an Order and the Imperial Lieutenant Office will definitely send someone to investigate him.

If it is found out that Liu Zhang did it, then it will be a big trouble.

Abandoned Wu was both moved and worried, Chen Yun told her last night that he would avenge her.

I didn't expect this revenge to come so quickly, and this matter spread throughout Chang'an.

Gongsun Duan's incident also caused quite a stir.

The Gongsun family was disgraced, and Liu Che soon learned that several children of the Gongsun family had been killed.

They were bound and hung on trees, and their killers were deliberately humiliated.

They didn't have a single piece of clothing on, and people came and went, and they passed by the tree and saw it.

They saw it, and they had wooden signs hanging from them.

It also wrote about some of the sins they had committed, and Gongsun He was very angry about it.

He also received a warning letter asking Gongsun Jingsheng to be honest recently.

Otherwise, he would be next. The Gongsun family should not be too arrogant.

Don't think that if you get the emperor's favor, you will be lawless.

It's no wonder that Gongsun He is not angry, he went outside the palace early in the morning.

Asked to see Liu Che and asked him to let the Imperial Lieutenant Office investigate the matter.

The Imperial Lieutenant Office received an edict from Liu Che to investigate the murder of Gongsun Duan and others.

Let Zhang Tang and Jiang Chong investigate together, Liu Che suspects that this incident was committed by the same person as the murder that happened last year.

At first, it was suspected that it was related to Liu Zhang, but various evidence showed it.

Liu Zhang had no motive for committing the crime, and there were many people who proved that he was not at the scene of the crime at the time of the crime.

Zhang Tang and Jiang Chong took people to the autopsy, and a total of thirteen people were killed.

Seven were the sons of the Gongsun family, and six were their servants.

They had no visible injuries on their bodies, and upon examination, they had no internal injuries.

There were no signs of poisoning, and the good people died in vain.

This technique is the same as that of the people killed last year, and no injuries can be found.

Last year's case has been investigated, and they have investigated Gongsun Duan's residence.

It was the first scene of the crime, and Zhang Tao and the others did not find any clues.

Even if there were, they were cleared, which made it more difficult for them to investigate.

Moreover, there were no signs of a fight in Gongsun Duan's residence, and the body was transferred under the big poplar tree.

Their bodies were tied up and hung like rice dumplings on thick branches.

The branches are also five or six meters above the ground, which is difficult for the average person to do.

They had wooden signs on them that said they had made mistakes before.

Someone reported to Zhang Tang and Jiang Chong that Gongsun Duan's servant brought a beautiful woman yesterday afternoon.

The beautiful woman remained in a coma, and later took her out of the house.

That beauty didn't know whether she was alive or dead, and she didn't know whether Gongsun Duan was their death. Is it related to this matter?

Zhang Tang asked the witnesses to describe the appearance of the beautiful woman, who was just cleaning the courtyard at that time.

still had a little influence on that beauty, Zhang Tang personally painted the appearance of the beauty described by the witnesses.

After finishing the painting, Zhang Tang felt that the beautiful woman in the portrait was very familiar.

"This is the servant girl beside Honghou who abandoned me, how did she get here?"

Zhang Tang felt that abandonment was the key to this case, and it seemed necessary to go to Liu Zhang's mansion to investigate.

I wonder if I'm still alive? Gongsun Duan must have bullied her.

Then he sent someone to throw her away and leave her to fend for herself.

Yesterday, some young nobles went to visit Liu Zhang, and there were people missing in the mansion and they definitely didn't find out.

If this case is related to the abandonment of me, then bring the abandonment back to the court office for questioning.

For the time being, I can't be sure if she killed Gongsun Duan and others, and whether Liu Zhang helped her?

If the evidence is conclusive, then last year's murder case is related to Liu Zhang.

"Let's go to Honghou's mansion and inquire, hoping to find relevant clues."

Zhang Tang's thoughts are the same as Jiang Chong's, as long as there is a hint of clues.

He won't let it go, last year's case was not solved.

Although Liu Che did not blame, this was a shame and a challenge for Zhang Tang.

He has tried cases for so many years, and he has never encountered a case that cannot be solved.

Last year's murder did not have the slightest clue, it was the scene of the crime.

Any traces were removed, and at first it was suspected that it was related to Liu Zhang.

The secret investigation of Liu Zhang is not enough to prove that he is related to those murders.

Suspicion is suspicion, and everything must be evidenced, unless the emperor wants to punish that person.

Jiang Chong and Zhang Tang went to Liu Zhang's mansion together, hoping that the clues would not be broken.

Ask some people in Liu Zhang's mansion to see if you can find clues?

At this moment, Liu Zhang was playing chess with Chen Yun in the courtyard.

So far, there have been no visitors, and their home has been much quieter.

Abandongo is resting in his room, not during this time.

She wanted to get better as soon as possible and couldn't delay her own business.

Chen Yun prepared a variety of nutritional products for him to let her take good care of her body.

"I heard this morning that there was a murder outside Chang'an City, and it is estimated that the Imperial Court Administration will come to our house to investigate."

Liu Zhang was not worried at all, because they could not find evidence at all.

The so-called if people don't know, unless they do it.

In his opinion, this is not the case, what he asked the humanoid robot to do.

There were no traces left, and the Imperial Lieutenant Office could not find out even after a hundred years of investigation.

Liu Zhang himself has been staying in the house since last night.

The people who came into contact with him were all his relatives, and the servants could prove that he had not gone out.

Now that the investigation pays attention to evidence, Liu Che doesn't want to kill him yet.

"I've also heard that it may be that those people have offended others, and they have been punished."

Chen Yun knew that this was her Langjun's doing, and she would not reveal a word to others.

She has avenged the abandonment of me, and those people should be killed.

If it is handed over to the government for disposal, it depends on the relationship of the Gongsun family.

The punishment of Gongsun Duan and others is not painful, and they will be even more arrogant in the future.

Liu Zhang and Chen Yun are still playing chess leisurely, and his psychological quality is extremely high.

Even if Zhang Tang and them came to ask, he was still able to deal with it calmly.

After a while, the servants in the palace reported to Liu Zhangyu that Jiang Chong and Zhang Tang had come to visit.

Liu Zhang asked the servant to take the two of them to the living room, and he took his wife to the living room with him.

After Zhang Tang and the others left, the two of them continued to play chess.

Liu Zhang covered the chessboard with a cloth, and he played chess with Chen Yun before he could decide the winner.

The couple came to the living room, and Jiang Chong and Zhang Tang had just arrived in the living room.

"The two of you came to my house in a busy schedule, and I don't know what to do."

Liu Zhang also guessed the purpose of the other party's visit, but he still asked knowingly.

"According to our investigation, a servant girl named Qiwu in your house was taken to Gongsun Duan's house. Gongsun Duan and thirteen others were killed, and your handmaid was nowhere to be found. ”

Zhang Tang said directly, he wanted to make sure that Qiwu was in Liu Zhang's mansion.

She is not only a victim, but also an important witness.

"She did disappear briefly, she came back last night. She was injured a little and was recuperating in the house. ”

Liu Zhang did not hide it, if they were going to ask about the utensils.

Unable to get any clues, he was in a coma for a while.

She didn't know who hurt her, if Zhang Tang they didn't believe it.

Then use the Truth Potion of Confession, Zhang Tang They have seen the power of this potion.

The Truth Potion doesn't hurt the user much, and Liu Zhang doesn't want to let me take this potion.
