Because Zhu Gui was only allowed to walk around the East Palace, he would not be able to come to the imperial study without Zhu Yunwen, the imperial grandson.

And he also learned an information in advance, that is, the emperor has not been to the imperial study recently, which also avoids bumping.

But even if he really met Zhu Yuanzhang, Zhu Gui also thought of a reason, so naturally according to Zhu Yuanzhang's statement, he passed on the way of governing the country discussed with the prince to Zhu Yunwen.

Zhu Gui can be sure that no matter what is good, as long as it is good to Zhu Yunwen, then Zhu Yuanzhang will unconditionally agree.

Maybe this is because Zhu Yuanzhang feels that he owes too much to the prince Zhu Biao, so he wants to make up for it on Zhu Yunwen?

Zhu Gui didn't know the facts, and he didn't care.

He just needs to know how to catch Zhu Yunwen's 'death-free gold medal'.

As for why he came to the imperial study, on the one hand, it was naturally related to his excuse of 'preaching'.

On the other hand, Zhu Gui wanted to find a treasure in this imperial study.

That is the blueprint of the famous Daming treasure ship even in later generations.

At that time, Zheng He went to the West to take this kind of treasure ship, and there were 150 before and after, which made a strong mark in the history of world navigation.

Compared with the Dutch sailing ships that appeared more than 200 years later, I don't know how much more advanced the Daming treasure ship is.

It's just that the construction drawings of the Daming treasure ship have not been handed down.

The reason is that the Ming Dynasty's sea ban measures caused this precious drawing to be shelved because it was no longer useful, and then it was gradually lost.

But Zhu Gui didn't forget about it.

At this time, although there were still decades before Zheng He went to the West, Zhu Gui believed that the developed shipbuilding industry in the Ming Dynasty should have been accumulated and inherited.

Otherwise, such an advanced charter ship could not have appeared out of thin air.

And the super battleship with a length of more than 100 meters cannot be afforded by the people, and the design drawings of the treasure ship are most likely in the imperial study.

Thinking about this, the corners of Zhu Gui's mouth couldn't help but curl.

If he could find the blueprints of the treasure ship, he would probably have to change his development strategy.

Datong Province was located in the interior of China, and Zhu Gui's previous strategy was to use the land route of Datong to the Eurasian continent, and then connect the entire continent by rail.

Only adequate and convenient transportation will not tear a super-empire apart.

However, the difficulty of implementing this plan is also very staggering.

Even if all the current population of the Ming Dynasty is counted and the railway is built together, I am afraid that this huge plan will not be completed in a hundred and ten years.

Not to mention that this is not counting Zhu Gui's complete conquest of other peoples on this continent.

But once you have a treasure ship, or even an entire fleet, it's different.

In this era, Europe was still in the era of small sailing ships, and treasure ships were comparable to the existence of aircraft carriers in later generations.

Zhu Gui could have controlled other forces under his command before they had fully developed through the sea strategy.

"Uncle Huang, are you okay?"

Zhu Gui was thinking about it when he suddenly heard Zhu Yunwen's voice asking.

It turned out that the two had already entered the imperial study, and Zhu Yunwen saw Zhu Gui standing motionless in place, with a smile on his face, and finally couldn't help but wake him up.

"Ah, Uncle Huang is fine, Uncle Huang is just amazed that there are so many things in the imperial study."

Zhu Gui was very skillful and casually found a reason.

But he was right.

This imperial study covers an area of more than 10,000 square meters, which is larger than a palace, and there are many bookshelves on both sides, reaching to the ceiling, and there are many ladders for climbing up and down to get books nearby.

"Uncle Huang, haven't you been to the imperial study before?" Zhu Yunwen asked with some curiosity.

This question made Zhu Gui quite embarrassed.

In the past, when Zhu Gui was the prince, as long as he didn't bump into Zhu Yuanzhang summoning the minister in the imperial study, it was still easy to enter and exit the imperial study.

But at that time, Zhu Gui only cared about being naughty and mischievous, studying how to play tricks on people, and was not interested in reading at all.

This is something that almost everyone in the palace knows, and only Zhu Yunwen was young at the time, so he didn't know much about it.

"This, Uncle Huang was not very interested in reading books before, that is, in the last few years, he has only known the benefits of reading, okay, you go and find the books you have read and show them to this king."

Zhu Gui wanted to break up Zhu Yunwen, and then study the layout of this imperial study.

With so many books, there must be a pattern of placement, right?

However, Zhu Yunwen did not leave when he heard Zhu Gui's words, but pointed to the direction to the right of the gate and said, "Uncle Huang, that is where I studied." ”

It turned out that the crown prince Zhu Biao, father and son, both had a special 'office' place in the imperial study.

And it also became a place for Zhu Yunwen to study.

Zhu Gui was quite helpless in his heart, but the words had already been spoken, so he had to go there with Zhu Yunwen, but he was thinking about how to find the design of the treasure ship in this vast sea of books?

It's not that he didn't want to look for a better solution in the system store.

But the items in the system are far ahead of their time, especially those related to technology.

Although it is powerful, there is also a problem, and that is the need for preconditions.

For example, the few ship-related drawings that Zhu Gui has unlocked now do not need to unlock the steam engine to build.

And the largest of those ships was only 100 meters long, far less exaggerated than the treasure ships of the Ming Dynasty.

Not to mention that the experience required for shipbuilding drawings in the system is even more astronomical, and Zhu Gui simply can't afford it in a short period of time.

And he needed not just a ship, but a fleet, so after thinking about it, he still felt that it was more appropriate to take advantage of the existing conditions.

Zhu Gui followed Zhu Yunwen and soon came to a corner of the imperial study.

There are still a lot of folds on a huge nanmu desk with a smooth color, which should have not been approved by the prince before he fell ill.

Behind the desk is a horizontal recliner, large enough for a tall man to rest.

From the oil lamp on the desk, it can be seen that the prince should have been here all night in the past.

Zhu Gui couldn't help but feel a little moved in his heart.

However, his thoughts were soon interrupted by Zhu Yunwen's voice.

"Uncle Huang, on this shelf are the books that my father assigned me to read, and I have only read the top two rows at present."

Zhu Yunwen pointed to a huge bookshelf more than three meters high next to the desk and introduced it to Zhu Gui.

Zhu Gui looked up at this bookshelf, and couldn't help complaining in his heart: "It seems that I used to think that I read more books than him, and I really think too much of myself." ”

There should be no less than a thousand books on this shelf.

However, a mahogany box in the center of the bookshelf caught Zhu Gui's attention.
