"Young Master?" Mo Yan looked at Mu Tinglan with some concern.

Mu Tinglan came back to her senses and then restrained her emotions, "What's wrong with Sun's Mansion now?"

"It has been seized." Mo Yan said.

After pondering for a while, Mu Tinglan stood up, "Mo Xiang and I go to Chengtian Mansion together, Xin Wu, take care of it for the time being."

"Yes." Mo Yan replied,

Then Mu Tinglan and Mo Xiang left Lan Mansion and walked towards Chengtian Mansion.

In Chengtian Mansion, Lord Liu walked in front with an unexpected expression, but Gu Heng still looked indifferent. They went to examine the two assassins last night, but they still couldn't get too many clues. The only thing they got was that only one of the five assassins had a cloud tattoo on their bodies, and none of the others were on their bodies.

But at this moment, Lord Liu really hopes that these people have tattoos on them, so it will save more effort to investigate, right?

"Have you found the person who leaked the news before?" Mr. Liu asked Lord Cao, the magistrate of Chengtian Mansion who had been waiting in the hall. Lord Cao had only been in office for a few years, but he was also considered Lord Liu's right-hand assistant.

"Sir, please forgive me, I haven't found it yet." Mr. Cao said with some shame.

After all, there are no clues, so it is really difficult to check.

Lord Liu was even more upset and waved his hand, "Forget it, no matter who it is, he will always be exposed at that time." He said, "You go down first."

"Yes, sir."

After Lord Cao left, Lord Liu looked at Gu Heng, "Zi Xun, I wonder if you have any ideas?"

It is really difficult for the assassin to pry open his mouth. It is really difficult to find clues about the private salt case and private weapon case through Sun Pingzheng and others. Perhaps the people behind these assassins are only targeting the official silver case, but don’t forget that the official silver case is actually a combination of the private weapon case. If you want to cast weapons, iron ore, coal and various materials, you need to buy them, but where you buy them, you have to check it.

Since Sun Pingzheng cooperated with others to rob the official silver and found a workshop for privately-made weapons in the place where the official silver was hidden, these two things can actually be linked together. But now there are not many clues about privately-made weapons. How long has the weapon casting workshop existed? How many weapons have been sent out? They all know nothing about these, and they can't even find the account book.

Mr. Liu has also tried several times to review Sun Pingzheng and other related people, but they all know nothing about the account book. But Mr. Liu believes that even if others don’t know, Sun Pingzheng will definitely know.

After investigation, Sun Pingzheng has been leaving Ancheng for a period of time in recent years, saying that he was going to a nearby village to relax. Lord Liu felt that Sun Pingzheng was actually just using this name to secretly go to Xiaolinzi Village.

"Sir, you can go to Sun's house to look for it again." Gu Heng thought for a while and said.

"The Sun Mansion has been searched all over, and the secret rooms of the Dark Pavilion have been found." said Lord Liu, "I have also searched for it in the Sun Mansion's village."

The most annoying thing is that you can't find the account book. With an account book, you will also avoid a lot of trouble.

If you look for this case one by one, I don’t know when to find it. The most important thing is that there may be a great big fish in the account book. Although he may not be able to catch the big fish in the end, it is also very good if he can move it.

He, Liu De, just likes challenging cases.

"Sir, Lord Gu, outside, I thought Mr. Lan was asking for a visit." The guard walked in and reported.

Young Master Lan? Lan Muting?

Lord Liu looked at Gu Heng, and then he asked someone to invite Mu Tinglan in.

This is not the first time Lord Liu has seen Lan Muting, but looking at the person coming in, Lord Liu still has to exclaim in his heart, what a handsome young man.

Gu Heng looked at Mu Tinglan, but his eyes moved. General Mu had already returned to his house. He thought Mu Tinglan would seize the time to move the second room.

"I have met Lord Liu, Lord Gu." Mu Tinglan bowed slightly.

"Young Master Lan doesn't need to be polite." Lord Liu said with a smile, "Young Master Lan has helped us a lot this time." If Lan Muting hadn't brought Wei Mingjie back, it would probably be so easy to find Sun Pingzheng.

Maybe it's not bad.

"You are polite, Lord Liu, but he happened to save such a person. He didn't expect Mr. Wei to be related to the Guanyin case." Mu Tinglan said, "But he sang a good show last night."

Lord Liu laughed again when he heard this, "It's so easy to say, thanks to the cooperation of the people from the Lan Mansion."

"Young Master Lan comes to Chengtian Mansion and don't know what's wrong?" Gu Heng looked down on Lord Liu's smugness at all. The show last night seemed to be his own idea. This boss was not ruthless at all by robbing his subordinates' credit.

Mu Tinglan raised her eyebrows and said, "Actually it's not a big deal. Later, Lord Gu helped find the inner demon in the mansion again."

"Have you found the leaked secret in the Lan Mansion?" Lord Liu became serious in a second, "Honest Master Lan found the person behind it?"

Mu Tinglan shook her head, "I was caught, and I was the housekeeper in the mansion. The housekeeper was previously from Lord Zhao's mansion, but later after Lord Zhao's family was confiscated, he was sold to the business. However, after investigation, the man was working as a servant in Sun's mansion earlier."

The man in the Sun Mansion.

Lord Liu's heart moved, "Mr. Lan means that the butler is from the Sun family. He knows that Mr. Wei's existence may threaten Sun Pingzheng, so he reveals the news?"

"This is the only possibility." Gu Heng said, "But Sun Pingzheng and his family have always been locked in Chengtian Mansion. No one is allowed to meet with each other privately. How did they convey the message? Or, who did the butler reveal the news to?"

"Sun Pingzheng is just an executioner, and there must be a big fish behind him. I guess the butler knows this, so there is no need to contact Sun Pingzheng at all. As long as he reveals the news, the person who should know will know." Lord Liu said, then looked at Mu Tinglan, "Young Master Lan, what news did the butler reveal?"

"He just sent the news to the Sun Mansion. There was a small river behind the Sun Mansion. He contacted the people in the Sun Mansion there." Mu Tinglan said, "So it is still unknown who is behind Sun Pingzheng."

It is too early to make a conclusion whether it is the third prince, the second prince, or the unknown force.

But, she originally revealed this news to Gu Heng to deal with the third prince, so it is mainly necessary to lead it to the third prince.

Thinking of this, Mu Tinglan said again, "I heard that the assassin last night had a cloud tattoo on his body. You can start from this aspect. Li is already dead. It's impossible that the subordinates he trained inherited his will and wanted to make trouble, right? I always feel that something is wrong."

"After investigation, it was indeed related to Li, and Li admitted it at that time." said Lord Liu.

Upon hearing this, Mu Tinglan looked at Lord Liu with a smile, obviously not believing in Lord Liu's nonsense.

Lord Liu... This is not nonsense, it is a fact, did Li not admit it?

"Sir, I actually came down and wanted to find Lord Gu to visit Sun's mansion together." Mu Tinglan changed the topic, and Lord Liu was also a slippery person.

"Young Master Lan wants to go to Sun's Mansion?" Gu Heng was a little surprised, but when he thought about it, he felt relieved. It must be Mu Tinglan who got some news from Sun Wu.

"That's right, Sun Wu knows some things about the Sun Mansion. I think there should be something good about the Sun family." Lan Muting said.

"Young Master Lan is very interested in this matter." Lord Liu said deeply.

Mu Tinglan smiled slightly, "I'm very interested. After all, those people caused some losses to the Lan Mansion last night. I also bought a person with dissatisfaction. I feel very unbalanced."

Lord Liu….Haha.

Gu Heng... This reason is really far-fetched. Anyone can hear it is very perfunctory.

However, although he was disdainful of this reason, Lord Liu did not refuse. Instead, he decided to go to Sun's Mansion with Mu Tinglan and Gu Heng. He also wanted to know how the butler of the Lan Mansion and the Sun family conveyed the message.

With the people, the group soon arrived at Sun's Mansion.

The Sun Mansion has been sealed, but the things inside have not been passive yet. In order to avoid missing important clues, there have always been people here to take charge.

"This Sun Mansion is also quite luxurious." Mu Tinglan stood in the hall and took a look. There were several expensive decorations in the hall alone.

"After investigation, Sun Pingzheng also accepted bribes. Some of these were sent by the people below to curry favor with Sun Pingzheng." Lord Liu explained, "Why don't we go to the back door of Sun's mansion to take a look first?"

"Okay, let's go." Mu Tinglan nodded and said.

"By the way, I don't seem to have heard of Mr. Lan these days. Mr. Lan went out for a trip?" asked Lord Liu.

"Where is the leisurely thing? I'm going out to find a way to make money." Mu Tinglan said, "After all, in addition to coming out to see the world, I have to do something and achieve some results, so that I can look better when I go back, right?"

Gu Heng stood beside her and couldn't help but look at her when he heard this. The general's house is as big as a family business, but still lacks the little things she has?

But Lord Liu didn't know that the people around him would be Princess Anping, so he admired Mu Tinglan's words very much, "Young Master Lan is young and promising, but he is afraid that he can't achieve anything?" A young man with goals is a good young man.

No wonder I was able to know Gu Heng and become friends with Yan Yonghong and the others.

"Sir, I've praised it."

While talking, everyone walked through the courtyard corridor and soon came to the back door. There was really no one guarding the back door. After all, it was still a little distance from the various courtyards of the Sun Mansion. After opening it, we came to the back of the Sun Mansion. There was a small road behind it, and there was a small river flowing by the side of the road.

"Sun Wu told him that if there was any news, he would write it on a note and then buried it under the tree in front of the back door." Mu Tinglan said.

Lord Liu nodded when he heard this, and then asked someone to dig there to see if he could get any news.

After digging for a while, the yamen was indeed digging a box from under a tree, but the box was empty and should be used to hold paper strips to avoid the paper strips becoming blurred when they get damp.

"There is really something." Lord Liu took the box and looked at it. It was just an ordinary box. "It's a pity that it's empty."

"Sir, you can send some people here to guard it, and maybe you can wait for something to wait for." Gu Heng said.

Lord Liu snorted, "What else can I wait? The other party is not a fool." Although he said this, Lord Liu ordered someone to carefully guard the back door. If there is a suspicious person, he immediately returns to the Sun Mansion.

Mu Tinglan was not very interested in other parts of the Sun Mansion, but she had to go to the study room of the Sun Mansion.

In his previous life, the account book of Private Salt seemed to be found in Sun Pingzheng's study.

"In this study, I found two dark pavilions and one secret room." said Lord Liu, "There are many gold, silver and treasures in the secret room. Several letters were found in the dark pavilion, but they were not helpful to the case."

Gu Heng and Mu Tinglan carefully observed the study. This was also the first time Gu Heng came to Sun's mansion. When he was arrested before, he was sent by Lord Liu to Xiaolinzi Village to investigate again, although he did not find any evidence of exerting force.

"The Qingfeng Bamboo Forest Picture of Master Yulin, Master Dawu's original works, tsk, Sun Pingzheng's family also has a lot of treasures." Mu Tinglan was amazed. Even the calligraphy and paintings in the study room could be bought for a few more Sun Mansions. The calligraphy and paintings I just saw were a drop in the bucket. "There are actually lonely books. tsk, these will be filled into the national treasury at that time?" She didn't like the others, but she was a little interested in the lonely books.

"That's right." Mr. Liu nodded. Mr. Lan is quite sensible. You can see at a glance that there are many treasures here.

Gu Heng's attention was not all that. When he heard Mu Tinglan's words, he just raised his lips secretly and then looked at the study room again. There were many treasures in the study room, but the layout was quite elegant. When he walked to the bookshelf, Gu Heng looked at it. There were three bookshelfs in the study room, which were either books, or various calligraphy and paintings and treasure decorations. I have to say that the Zuo Shilang's family is really rich, although many things cannot be taken out to meet people.

But Sun Pingzheng is also bold enough. Even if he is not afraid of thieves thinking about it, he is not afraid of outsiders coming to see this and will he feel suspicious?

After looking at it, he was about to turn around and look elsewhere, but he immediately stepped aside, first looked at the first and second rows, and then looked at the second and third rows. The distance between the front and back seemed a little different.

"Did Lord Gu show something?" Lord Liu had a good look and saw Gu Heng at once.

Gu Heng shook his head, "The distance seems to be a little different." But perhaps it was just a chance.

Lord Liu and Mu Tinglan walked over and saw that they were really different. The distance between the front and back of the bookshelf was very different. Although Sun Pingzheng might not care about these details, the distance between the second and third rows was really too narrow, but it was just enough for one person to pass through, and you had to be careful when turning around, otherwise you would encounter something on the bookshelf. Such a distance was obviously abnormal.

"I haven't paid much attention to it before." Lord Liu looked, "but there was no mechanism found here, and there was no information about the account book in the books."

Gu Heng looked at the bookshelf and looked at the space where the bookshelf was placed. He felt a little awkward. The bookshelf was actually on one side of the desk, but the bookshelf here was obviously used for displaying and not many books were collected. There was also a bookshelves behind the desk. The bookshelf was placed on the bookshelf, and the mechanism in the secret room was there.

Gu Heng frowned, then walked to the desk, but it was found that the middle of the two sides was also partitioned, and the spaces on both sides were obviously different. The last row of bookshelfs on the other side was less than the size of a palm. However, on the same side of the study, the wall had to be two feet away from the same position.

Mu Tinglan followed and still realized this situation.

"Good guy, Lord Sun is also amazing." Mu Tinglan sighed.

"What's wrong, you've seen it?"

"There should be a dark room behind the bookshelf." Mu Tinglan said, "Is it different for Lord Liu to see the inside and outside space?"

Upon hearing this, Lord Liu looked carefully and found that this was really true, and he had not seen it before.

"The difference will not be very big, it is easy to be ignored." Gu Heng said lightly, "But it is not too late to show up now."

"That's right, that's right, thanks to Mr. Lan. If Mr. Lan hadn't suggested to come and have a look, maybe we wouldn't be able to find these things."
To be continued...
