Zhu Ying knew that this method must have been arranged by Yao Guangxiao.

But Zhu Ying really couldn't figure out why Zhu Di and Yao Guangxiao were targeting him like this.

Judging from the current situation, what else do I have in my hands except snowflake salt?

Why do you keep staring at me?

There was no obvious sense of malice, which made Zhu Ying a little confused and unable to analyze the purpose at all.

"Boss, does the King of Yan take a liking to you?" Weng Sheng, the Mongolian man said.

Zhu Ying was stunned, then glared at the Mongolian man fiercely: "If you can't speak, just say less. No one thinks you are dumb."

Of course he understood what the Mongolian man meant, and this possibility was also something Zhu Ying had thought of.

As the Yongle Emperor who was praised by later generations, he must have attached great importance to talented people.

Zhu Ying never belittles himself. From another perspective, or from the perspective of others, Zhu Ying must be a person with natural talent.

At the young age of ten, he had established such a large chamber of commerce in just ten years. Even if Zhu Di had only discovered a small part of Zhu Ying's background, it was still extremely shocking.

From Zhu Di's perspective, he naturally wanted to recruit such talents for his own use. Besides, Zhu Ying mainly traveled in the Western Regions and grasslands.

It is more important for Zhu Di to be familiar with the various tribes and the situations of other small countries.

Once Zhu Ying is conquered, Zhu Di will gain unimaginable benefits from conquering the various tribes on the grassland.

If he had met Zhu Di a few years earlier, even three years earlier, Zhu Ying might have considered following him.

But now, it's totally impossible.

Thinking of this, Zhu Ying began to plan how to leave Beiping City.

Judging from the current situation, although it is quite difficult, there is still a way if you really want to leave.

However, in order to avoid excessive losses, Zhu Ying must plan carefully, and time waits for no one, so he must act tonight.

Just when Zhu Ying was deep in thought, one of his subordinates came in to report that the eldest prince of Yan, Zhu Gaochi, had arrived.

"What is he doing here?"

Zhu Ying was a little confused and went out to greet him.

In the yard, a young fat man was waiting.

Although Zhu Gaochi is fat now, he still looks like a normal person at present, and is not as fat as he will be in the future.

After all, he was only fifteen.

When Zhu Ying saw Zhu Gaochi, he felt a little sorry.

This is obviously a disease, which is difficult to solve in later generations, let alone in the current Ming Dynasty.

"Brother Ying." Zhu Gaochi was very happy to see Zhu Ying. Although he had not been in contact with Zhu Ying for a long time, he regarded Zhu Ying as a close friend.

"Why is the eldest prince here? Could it be that he missed me?" Zhu Ying teased with a smile. He still had a good impression of the little fat boy Zhu Gaochi.

Zhu Gaochi liked to read Confucian books, but he was not as bookish as ordinary people. He also had great interest in other subjects.

As a person from later generations, Zhu Ying may not have the professional depth, but when it comes to chatting, there is absolutely no problem at all.

Zhu Gaochi soon discovered that Zhu Ying seemed to know something about astronomy, geography, and various schools of thought. Although his knowledge was a bit miscellaneous, his extremely broad knowledge made him yearn for it.

With Zhu Ying's deliberate contact, the two soon became good friends who could talk about anything.

"Of course I miss you, but I came here today mainly because of my father's wish. Tomorrow you will go to Nanjing with us."

"My father asked me to come and see if you need any help." Zhu Gaochi said casually, without any hesitation, and found a chair in the main room to sit on.

Mainly because he gets tired easily after standing for a long time.

Zhu Ying waved his hand and asked the servant to prepare tea. He sat down next to Zhu Gaochi and asked casually:

"Oh, it's Prince Yan's arrangement. Does Prince Yan have any instructions?"

"I didn't say anything. Maybe I was afraid that you might be unhappy, so I came to comfort you."

Zhu Gaochi spoke directly without any taboos in his words.

Zhu Ying was speechless. He had already decided to leave. As a businessman, he knew the status of merchants in Ming Dynasty today.

If he were to arrive in Nanjing, the capital of the Ming Dynasty, anyone would be able to look down on him.

He is living a carefree life now, so why should he go to the capital?

"I heard that the capital is very lively, so I will have a chance to go and see it this time." Zhu Ying said perfunctorily.

When Zhu Gaochi heard this, he suddenly became excited and said:

"It's lively everywhere, but the key is the source of our Ming Dynasty's firearms, which is in the military equipment bureau in the capital. I will talk to my father about it when the time comes."

"Let's see if we can get a chance to go in and take a look. I think the firearms in the capital must have many more styles."

When Zhu Ying heard this, his eyes suddenly lit up.

He has been coveting Ming Dynasty's firearms for a long time. Now, Ming Dynasty's firearms are the best in the world.

According to later records, Zhu Di attached great importance to firearms.

However, after Zhu Ying came into contact with him, he found that although Zhu Di also attached importance to it, he did not go to the stage of in-depth research, or the degree of his attention was very different from what he had imagined.

To a large extent, Zhu Di paid more attention to personal strength or military strategy.

In Zhu Di's eyes, firearms are just more convenient weapons.

However, today's firearms have not yet reached a very strong level.

The main direction of rapid development of Ming Dynasty firearms was still mainly cannons.

After all, today's gunpowder is still in powder form and has not formed into particles. In terms of killing power, the short gun's lethality is not that terrifying.

However, after communicating with Zhu Gaochi, Zhu Yingcai discovered that he was the one who was most interested in firearms in the entire Prince of Yan's mansion.

The biggest common topic between the two was firearms.

After hearing this, Zhu Ying's thoughts raced, and he suddenly didn't feel so resistant to going to the capital.

Given Zhu Ying's current situation, it is too difficult to carry out advanced research and development of firearms.

Zhu Ying only remembered the words "one sulfur, two nitrate and three charcoal", but he had no idea about the others.

As for the use of gunpowder, it was quite common during the Tang and Song dynasties, so it was completely meaningless.

Besides, most people in later generations would not study this thing.

Apart from knowing a general direction of development, Zhu Ying really only had a vague understanding of it, but there was no problem in fooling Zhu Gaochi.

After some thought, Zhu Ying decided that this trip to the capital was still necessary.

It would be even better if we could go to the Armory to observe and even ask a few firearms craftsmen to come and meet them.

After chatting with Zhu Gaochi for a while and then seeing him off.

Uncle Zhang asked, "Boss, what are your plans for tonight?"

Zhu Ying thought for a moment and said, "Uncle Zhang, take a dozen people who speak good Chinese with you and go to the capital with me tomorrow. The rest of you can go back to the Western Regions directly."

"Yes, Boss."
