Xu Yi is really unwilling.

I spent the whole night in a tangle, and I didn't know when I fell asleep.

"Put it back."

Yingniang was probably worried that Xu Yi slept last night and didn't hear it. I'll let you know again early in the morning.

"Yingniang, Li Song's treasure house······"

"It's very inconspicuous, it's the most dilapidated and marginal house in his house, next to the wall."

Next to the wall...... Xu Yi's heart itched even more.

Xu Yi was not the kind of person who harmed others and himself, but in the face of Li Song, he felt that there should be no burden.

Even if it is to destroy the Nine Clans, it seems that there should be no burden.

Besides, the Dasheng Dynasty seems to be really confident, and it never cares about the descendants of the rebellion, there are many descendants of the previous dynasty, and the descendants of the rebels are all court officials.

It seems that the Great Sheng Dynasty is only aimed at relatives.

Sometimes Xu Yi wondered if he would also expose the Xu family of Gaoping Beizu's house......

I thought about it and continued to think about the jade seal.

The information I got from Old Man Cui was obviously as Xu Yi expected, that thing was indeed not something that could be collected by the palace.

I don't know where Li Song got it, but he dared to hide it privately.

During this period of time, the relationship with Li Song has eased, and it is a good time to cheat him, can you operate it?

The question is how to pit him.

I can't write a bullet seal and say: I know that Li Song's family has a jade seal......

As for directly leading people to attack the left-behind mansion, it is estimated that he will not be able to receive the treasure trove of others, and he will be dismissed first.

Let out the rumors? It's even harder. I am not a big family with dozens or hundreds of years of inheritance, there are only seventy or eighty people in this family, and whoever puts rumors will be covered in.

Alas, it is not very easy to pit people.

can let Li Song's private jade seal in his house be unhindered, Xu Yi is really unwilling.

At this time, Xu Yi didn't think about the grievances between the Cui family and Li Song, and he didn't even think about his entanglement with Li Zhen, including Li Song, it was more like jealousy...... Well, it's not all, there is still resentment in it, otherwise if he knew that the Cui family had a private jade seal, Xu Yi would not have thought about pitting it.

Let's take a look first.

Therefore, Xu Yi asked Zhao Zhonghan to patrol the streets, and the beautiful name is that the New Year is approaching, and he needs to focus on patrolling to ensure that the people of Dongdu can have a happy and peaceful New Year.

At the same time, he also reported this inspection to Henan Mansion and the Left-behind Mansion, which is called a justifiable name.

It's just that Zhao Zhonghan didn't understand why he had to take Miss Ying with him......

"General, this is Jishan Fang, and the other courtyard left by Li is in this Fang."

The huge eastern capital turns all the squares, even if it takes two or three days to ride in a carriage.

You need to pretend to be unintentional, and you have to be careless, and only after the next day did Xu Yi transfer to Jishanfang.

Xu Yi looked at Yingniang, and Yingniang nodded slightly.

Yingniang didn't understand what Xu Yi was going to do, so she finally took it out and let herself put it back, but since she put it back, she let herself follow to confirm it.

The point is, come on, shake such a big circle.

You have to do it without going around in circles!

There are thousands of Wuhou people, are they really their diehards? So far, Xu Yi has not said anything about his purpose.

"Lao Zhao, these walls are all bricks and stones? How about burglar and fire prevention? ”

"Lord Hui, except for the palace, all the walls are not bricks and stones, and even the walls of Chang'an are not bricks and stones."

"General, the wall of the square is lined with bamboo knots, and the outside is tamped with earth, which is no worse than masonry in defense."

Zhao Zhonghan did not tire of it, and even answered some naïve questions truthfully.

Also, the lord is a noble man, so he can understand what these subordinates do. Even the accompanying Wuhou didn't think it was strange.

Xu Yi has asked a lot of very messy questions in the past two days, almost idle.

I wanted to ask about the wall for a long time, so I waited until Jishan Fang, and waited until the Fang where Li Song's courtyard was located. Xu Yi needs to determine the material of this wall.

Xu Yi looked at Yingniang again, Yingniang rushed forward a few steps, seemed to have reached a corner, and patted a few times inexplicably.

"Miss Ying, in the wall is the courtyard where Li stayed. Li stayed behind most of the days in the courtyard ......"

Xu Yi continued to pretend, Yingniang didn't understand what Xu Yi wanted to do, although she was stupid and sweet, she also knew what to say and what not to say.

It really seems like an accident, just passing by.

Xu Yi's inspection was really seen by the officials and people of the entire Eastern Capital.

After returning home from a day's inspection, Xu Yi went straight to the courtyard in the corner of Xu's mansion.

It is the courtyard where Ling Yunzi pondered alchemy.

"Uncle Yun, how much alum oil do you have?"

Earlier, Ling Yunzi had tinkered out alum oil, which was sulfuric acid, which was very impure.

Xu Yi told him to keep it at that time, and he also told Ling Yunzi a lot of nonsense.

Xu Yi really hopes that there will be a chemist in his family, and he doesn't mind informing him of some sulfuric acid-based chemical changes in later generations.

Ling Yunzi pointed to the clay pot in the corner: "This thing is terrifying, it has to be packed in a clay pot, and even copper and iron can be dissolved." I guess this is the bone-turning water I've heard......"

Xu Yi was stunned for a moment, in the end, he was from the rivers and lakes, and he actually wanted to turn bones into water.

Ying Niang was very interested in hearing this.

Xu Yi didn't think about it.

If it weren't for hearing Zhao Zhonghan say that the wall of the workshop was lined with bamboo joints, Xu Yi would have to consider other methods.

Since the walls are lined with bamboo knots, sulfuric acid is useful.

"Yingniang, tonight you bring some alum oil, find a piece of the wall that we haven't inspected yet, and sprinkle the alum oil into it......"

Yingniang looked at Xu Yi and didn't understand what he meant.

"Don't ask, I'll tell you what I'm going to do when the experiment is done."

Xu Yi wasn't sure if he could make it.

Sulfuric acid is not something that can melt everything, just like green bricks, sulfuric acid cannot be melted, and neither can clay pots.

However, in the case of bamboo, sulfuric acid can definitely melt.

The square wall is lined with bamboo, which is equivalent to the bamboo is the skeleton of the square wall.

If it can be poured out, Xu Yi will have a chance to try it down.

"Also, if possible, by the way, see if the walls of Li Song's treasury are brick and stone or bamboo clay walls."

This matter is too involved, and Xu Yi is not ready to let his family know everything.

Only Yingniang, who wanted to kill the second-grade members of the imperial court because she was wronged, made Xu Yi absolutely trust.

After refusing to be assassinated, for nearly a month, he kept wandering around Li Song's house, so detailed that he found such a secret treasure house as Li Song.

The next day, Xu Yi continued to inspect, which was also the last day of inspection.

Everything seems to be the same as in the past, Xu Yi and Zhao Zhonghan are idle, talking about some strange questions.

Zhao Zhonghan didn't pay attention, and when Xu Yi stopped, he also stopped.

Xu Yi seemed to be tired of walking, so he casually leaned against the wall of the workshop to rest.

When Xu Yi just hit the wall, he heard a sound of "Hulong", and the wall fell.

Xu Yi stumbled, pretending to be very similar.

"Will ...... Lord"

Zhao Zhonghan jumped up and was busy helping Xu Yi.

"I'm fine."

Looking at Yingniang again, I was completely stunned. What Xu Yi relied on was the place where she had splashed alum oil last night, and she pointed it out to Xu Yi.

It's just that I didn't expect Xu Yi to lean on so lightly, and the wall actually fell.

Yingniang's surprise, Zhao Zhonghan only thought that Yingniang had no experience.
