Zhu Yuanzhang had a different idea, he told Lu Ning directly.

"We all understand what Zi'an said in our hearts, but now it's not just about making money, if these vassal states buy things back, disassemble and manufacture them themselves, it will be a big loss, and the things we have researched ourselves are not for them to study."

Lu Ning thought for a while, and replied directly.

"Uncle said, I have already thought about this layer a long time ago, I have a suggestion, please refer to it."

Zhu Yuanzhang said anxiously.

"Okay, don't sell Guanzi anymore, let's listen to what you have in mind, and I believe that you will definitely be able to solve the problem for the imperial court."

Lu Ning immediately told Zhu Yuanzhang that his solution was very simple, that is, to open Daming branches in various vassal states and control the country's economy.

And the management of these companies is controlled by the Department of Domestic Products, which is actually equivalent to all the control in the hands of Yanwang Zhu Di.

At this time, Zhu Di was very happy with this suggestion, and he even introduced Lu Ning as a confidant.

After listening to Lu Ning's in-depth plan, although Zhu Yuanzhang was a little confused, he basically understood it and said it immediately.

"What Zi'an said is very reasonable, since this is the case, you will discuss it with the fourth child after this matter goes down, no matter what, we will have a supportive attitude."

At the same time, Zhu Yuanzhang immediately issued a holy decree to tell the envoys who lived in the Wanguo Pavilion about the opening of the Daming branch.

The other envoys didn't think much about it, but the crown prince of Goryeo felt that this matter was a big hole, so he told Li Chenggui directly.

"This matter can only be agreed, and then after we escape from the control of the Ming Dynasty, we will return to Goryeo to tell my father and Emperor Tianyuan on the side of the Northern Yuan, and ask them to send troops to help refuse the Ming Dynasty to open a branch."

At this time, Li Chenggui was thinking in his heart that this Goryeo prince was simply the place where his brain was pitted, and he wanted to rebel against the Ming Dynasty at this time.

If he hadn't negotiated a deal with Zhu Yuanzhang earlier, he would probably have to be buried with him.

But although he thought so in his heart, he still said flatteringly.

"His Royal Highness is very wise, this matter should be handled in this way, so as not to make Da Ming suspicious of us, I think His Royal Highness the Crown Prince is a man of divine martial arts, everything is subject to your arrangement."

The crown prince of Goryeo was very comfortable with these flattery, and he immediately promised.

"If everything goes well, when I get to China and take over the throne, you will be the number one general of our Goryeo Kingdom."

Although he secretly thought that this guy was a joke, Li Chenggui still flattered him, and then withdrew.

After that, he changed into civilian clothes and came to Lu Ning's Fuguo Mansion.

After the two met, Lu Ning asked straight to the point.

"Why, the things we agreed on have changed, do you regret it again, but this matter is voluntary, I haven't urged you."

Li Chenggui shook his head and said to Lu Ning a little speechlessly.

"Grandpa Guo, you are joking with me, in fact, I came to reveal a secret to you this time, the prince of Goryeo wants to return secretly, and colludes with Beiyuan to resist the opening of a branch by Daming."

Lu Ning shook his head and replied very indifferently.

"Your prince is a brain-dead, but the officials and generals of the Ming Dynasty are not brainless, do you say yes, I won't let him escape smoothly."

Li Chenggui also smiled and said in a low voice.

"This is a stupid Goryeo prince, and it won't do Daming and Grandpa Guo any good, but if you let him go back, you will secretly send someone to follow me back and help me kill the father and son of the king of Goryeo, which is really beneficial to Daming."

These conditions had already been negotiated, so Lu Ning didn't refute anything, so he said directly.

"Of course I can help you, but I have to remind you that the emperor once said that if you have any dissenting intentions, my three thousand elite soldiers of the firearms battalion will not eat dry food."

Li Chenggui broke out in a cold sweat in an instant, he knew in his heart that the firearms battalion was the elite of the Ming Dynasty, and it would not be easily dispatched.

If the firearms battalion really wants to be tough with him, the little troops under his command may not last a day.

Lu Ning directly found Lin Gui, the tiger general in his house, and said.

"You take my token, light the 3,000 firearms battalion and follow General Li to secretly set off, so that he can directly seize the crown prince of Goryeo and launch a coup d'état."

Lin Gui didn't ask anything else, and said with his fists clenched.

"Please rest assured, such a small task is not a big deal at all, I will definitely be able to complete it successfully, and then I will definitely come to return to the lord in a few days."

At this time, Lu Ning suddenly said again.

"You remember, if this General Li has any strange intentions on the road, you don't have to be polite to him, just come to me with your head on your head."

Although Lin Gui looked confused, he still nodded yes, and said in his heart that the lord was really comprehensive.

It scared this Li Chenggui so much that his face turned pale, and he hurriedly said that he didn't dare to make a mistake, and he must obey the arrangement of the Ming Dynasty.

Li Chenggui followed the prince of Goryeo to the halfway point, and suddenly raised his arms and said.

"Warriors, you are all born brave people, but now the king of Goryeo father and son are very mediocre, and they will lead us into the abyss."

Hearing this, the prince of Goryeo was completely stunned.

Things can still be played like this, it's just a little funny, this Li Chenggui is a general of Goryeo, if he jokes like this, he can't stand it.

The prince of Goryeo immediately hurried and hurriedly said.

"General Li, let's hurry up, don't mess around with me, I will treat you well when I go back and promote you to two levels."
