After Zhang Heng left, Chunyan, the maid beside Xingyun, told Xingyun that Lu Xingzhou was here again.

Xingyun was too lazy to deal with him, so she didn't see him directly, and when the people left, she called a guard and asked him to find someone to secretly follow Lu Xingzhou, remembering where he went, but not to be discovered.

Then Xing Yun entered Ye Shaoshuai's study.

The original owner has never been to Ye Shaoshuai's study, and the relationship between the brother and sister is neither too good nor too bad, mainly because of the original owner's personality.

And the original owner knows too much about this era and the current situation, but these are very important to the current Xingyun, so Xingyun can only come to the study to see if he can find something useful.

Usually, Ye Shaoshuai's study is not allowed to ordinary people, but now that the entire Shuai Mansion is ruled by Xingyun, there is naturally nothing that can not be entered.

The study is large, with a sofa for guests on one side in addition to office chairs, and a bookshelf on two walls, which are filled with books.

Xingyun turned around, there are many types of books on it, a small part is poetry, prose novels, most of them are military-related books, and many are related to construction machinery.

There were some files and documents on the desk, Xing Yun looked through them, there were reports on the taxes in the province, and there were reports from the various troops below to the above. Xing Yun first sorted out all the documents on the table, and had a general understanding of the territory and forces under Ye Dashuai, and then Xing Yun was ready to go to Dashuai's study to have a look, maybe she could also find something useful.

[Xingyun Xingyun, don't you want to find out if there is any dark room here? 】

Qizai's voice sounded very excited, and Xing Yun was a little speechless when she thought of it and the various Republic of China dramas that she watched with Meng's mother in the previous world.

[What you see on TV is not serious. 】

[But there may be!] Let's find out! 】

Okay, Xingyun began to rummage through the study, and it seemed that all the possibilities were trying to turn around, but nothing changed.

[I found them all, but I didn't. 】

[You didn't look carefully enough!] There are still hanging paintings that have not been turned over, and some places may be empty and you haven't knocked them! 】

[Heh, why don't you just scan it?] 】

Qizai's tone was a little aggrieved, [If I could, I would like to too, but I'm not level enough, these functions are not there~]

Xingyun rolled her eyes, looked carefully again, and really let her find the mechanism.

[I just said that there must be a mechanism!] Twist it open and see if there's a dark room! 】

As Xingyun twisted, the middle of one of the bookshelves slowly began to move forward, revealing the space behind it.

Xingyun walked in and found that it was a small room, with a small desk next to it, the table was full of various documents, and there were several boxes in the corner.

Opening the box, Xingyun found that one of the boxes contained half of the big yellow croaker, and the rest of the boxes contained all kinds of guns.

Very good, she found out that Ye Shaoshuai had hidden private money.

[Am I amazing?] Praise me, praise me~】

Xingyun smiled, [Yes, yes, you are the best! Thanks to you this time, if it weren't for you, I might have missed out. 】

The praised Qizai was a little shy, and he felt that it needed to work harder in the future to be a qualified auxiliary system!

After checking the box, Xing Yun began to look through the things on the small desk again, the things on it were more confidential than the things on the desk outside, and even Xing Yun saw some messages sent back by the spies that the Ye family had planted in other forces,

Xingyun immediately sat down and began to carefully read all the documents on it.

When Ye Shaoshuai went to suppress the bandits, he probably didn't expect that something like that would happen, so these documents were still kept, and some of them might have been thought of coming back to read again.

Through these documents, Xing Yun can know that there are those people in the army who are on the side of the young marshal, which is a relief for her at present!

There was one thing that caught Xingyun's attention.

This is a blueprint of the plant, and together with it are the purchase lists of various machines and the materials of some engineering personnel, and even some of the materials of university professors.

Young Marshal Ye intends to build an arsenal.

The place has been chosen, and it seems that the factory should be almost built, the equipment to be purchased has been negotiated, and even the technical staff have been found.

If Ye Shaoshuai was still alive, this arsenal would surely be built smoothly, and then slowly began to develop his own munitions.

Unfortunately, he's gone.

The original owner did not have any memory of this arsenal, and he did not know if the Lu family had discovered the back of this dark room.

This discovery made Xingyun a little surprised, originally she planned to solve the problem of the Lu family and build an arsenal after obtaining all the military power, and independently develop weapons.

After all, most of the arms of the warlords in the country are bought from the Foreign Affairs Office, which is not only expensive, but also people will not sell you the best.

At present, most of the domestic arsenals are copying foreign weapons, and there are often various problems.

Now with this, Xingyun's idea of building an arsenal is said to be half completed!

Except for going out for a meal halfway, Xingyun stayed in this small study for the rest of the day, studying and sorting out the things left by the young marshal without sleep or food.

"Uncle Yan, you remember, now no one is allowed to enter my father and my brother's study except me!"

At night, as soon as Xingyun came out, she told the housekeeper Yan not to let irrelevant people enter the study, and then returned to her bedroom with a book.

Lying on the bed, Xingyun opened the book she took out of the study.

This is a book about guns that Young Marshal Ye brought back from abroad, and it is all in German.

Xingyun is now glad that when she went to the last plane, she learned several languages in order to consult the original information files.

Sure enough, knowledge is the primary productive force, and if she didn't learn those languages, she was afraid that she would be blind, and she would have to spend time learning again.

Although there are differences in individual words, it does not affect reading, and Xingyun now needs to understand the current level of weapons and machinery in this plane, as well as the level of material and metal smelting technology, so that she can know how much of what she has in her mind can be made.

The next day, Xingyun originally planned to continue to go to the study to read, but yesterday the person she sent to follow Lu Xingzhou had to talk back.

Originally, she should have replied last night, but Xingyun didn't let anyone disturb her reading, so the guard waited early in the morning.

"Tell me, what did that guy do yesterday?"

Lu Xingzhou didn't enter the Marshal's Mansion yesterday, and after being refused, he first returned to his army, and did not come out for a day during the day, and then went to the famous Changping Hotel alone at night.

Looking at the guard's appearance of wanting to speak and stopping, Xing Yun leaned back on the sofa.

"I guess he didn't go to dinner alone, let's say, who is accompanying him?"
