(The second update, please vote for recommendation. Thank you book friend Xue Xi Tianxin, the book friend was not rewarded with 100 coins the day before yesterday.)

In fact, there are records of the production methods of granulated gunpowder in "Wu Beizhi":

To make gunpowder, use five kilograms of nitrate, one kilogram of yellow, and one kilogram of eggplant ash. A total of seven kilograms of nitrate, yellow, and ash are divided into three troughs, and crushed 5,500 times to the trough. For each 3 kilograms of medicine, use one kilogram of soybean wine, make mud, and then grind it into the trough, and then crush it for a hundred times to the trough. Mix it into particles, as big as yellow rice or mung beans, and it must be put into the palm of the person's palm and it will not feel hot before it can be.

Unfortunately, this granulated gunpowder has not been recognized by the court in history, and the official black gunpowder is still powdery.

Of course, Zhu Cilang needs to change this situation.

He wrote down the method of making granulated gunpowder and handed it to Gao Hongtu and said: "Da Sikong asked the people below to make gunpowder according to this method, so that he could meet my requirements."

Gao Hongtu took the pelletized gunpowder formula with his hands trembling, thinking to himself how could His Majesty the Emperor know about this?

When the Ming Dynasty released a carpenter emperor, would it be that he also needed a medicine emperor?

No, no, this idea is terrible.

Gao Hongtu shook his head.

It must be a method given by God. Your Majesty is the Emperor, and it is reasonable to be passed down by God in person.

"The old minister is obeying His Majesty's order."

Zhu Cilang was still very satisfied with Gao Hongtu's attitude. Although this person is a little less capable, he is very down-to-earth and willing to work hard. As the saying goes, diligence can make up for his shortcomings. As long as he can handle the firearms department according to his own wishes, it will be worthwhile that Zhu Cilang trusts and delegates power to him.

"There is another thing that Dasikong needs to be paid attention to. This method of making granular gunpowder must not be leaked. If I know who leaks the formula, the country's law will never be forgiven!"

Granulated gunpowder is of wide use. It can not only be used with firearms, but also make explosive packs. Although the explosive performance of black gunpowder is not as good as chemical gunpowder, it can still exert its outstanding power as long as it is used properly.

Neither Li Zicheng, Zhang Xianzhong nor the Qing Dynasty had mastered the preparation method of granulated gunpowder, which was a major advantage of the Ming Dynasty. Zhu Cixuan certainly did not want this advantage to be lost due to human reasons.

Therefore, he directly explained to Gao Hongtu and asked him to be responsible for the defense matters.

After explaining this, Zhu Ciyang left the Ministry of Works and moved to the Imperial Ming Military Academy.

On the one hand, he wanted to see the recent learning situation of the students in the military academy, and on the other hand, he wanted to meet Zheng Chenggong alone.

Not long ago, Zheng Zhilong replied, expressing his firm support for the idea of ​​the Emperor Huangming Chamber of Commerce.

Although Zhu Cilang knew that relying on the Zheng family to travel to the sea was not a long-term solution, Zheng Zhilong must be used at present.

Zheng Chenggong is undoubtedly the most important ace in Zhu Cilang. Although Zheng Zhilong is selfish by nature, he will never refuse to recognize his relatives until he has to.

After arriving at the Imperial Ming Military Academy, Zhu Cixuan cordially visited the students studying in the military academy.

The students in the Imperial Ming Military Academy are mainly composed of two parts: one is the sons and nephews of each warlord leader, and the other is the young talents Zhu Cixuan collected based on his understanding of history.

For example, Zhang Huangyan, Lu Xiangguan and others are all objects worthy of training. Zhu Cilang firmly believes that these people can be seamlessly connected after graduating from the Imperial Ming Military Academy and directly appointed to serve as officers in the Shence Army.

Of course, the most important thing at the moment is to get them to receive systematic military theory training.

The content of this part is naturally written by Zhu Cixuan, and then compiled into a book by a special clerk.

In this way, Zhu Cilang can ensure that military academy students are exposed to the purest military theory.

When the emperor arrived, everyone was nervous, and Zheng Chenggong was no exception.

Especially the emperor had to summon him alone, which made him take several deep breaths before calming down.

"I came here today to ask if I was the letter from Nan'anbo's reply to me true?"

"Your Majesty, what my father said is true. My Zheng family is willing to work hard for the Ming Dynasty!"

Zheng Chenggong was not stupid. He understood that the emperor asked him what he said was for temptation.

Although he understood that his father agreed to the emperor well and that he might hide his own private reasons in actual implementation, he could not hesitate at least when he promised the emperor.

As for my father, I can only advise you more.

"I heard you have an uncle named Zheng Hongkui."

Zhu Cilang mentioned it in a nonsensical and unpredictable manner.

"Your Majesty, this is the fourth uncle of the student."

"I intend to let him be responsible for the trade affairs of the Huangming Chamber of Commerce in the Fujian Sea, so that Nan'anbo can concentrate on coastal defense."

Zhu Cixuan proposed this idea carefully.

When Zheng Zhilong wanted to surrender to the Qing Dynasty, both Zheng Hongkui and Zheng Chenggong strongly opposed it, and in the end, Zheng Zhilong insisted on surrendering to the Qing Dynasty.

From this we can see that Zheng Hongkui still has a bottom line.

Zhu Cilang doesn't need Zheng Hongkui to stand on the side of the court. He only hopes that this person can separate part of Zheng Zhilong's power. In this way, even if Zheng Zhilong really has a second intention in the future, he will not be completely uncontrollable.

"This... Your Majesty doesn't know that the fourth uncle of the student has always followed his father to praise military affairs. However, the student believes that his father will definitely understand the court's painstaking efforts."

Zheng Chenggong could not answer Zhu Cilang directly, so he had no choice but to make up a reason to deal with it first.

Because no one knows better than him that my father was captured by military power and financial power.

If the imperial court sent someone to Fujian to take over the Huangming Chamber of Commerce, it would definitely be strongly resisted by his father. But what if this person was replaced by his own uncle?

Zheng Chenggong knew that among his many uncles, the fourth uncle was the most valued by his father. Maybe his father would agree?

Although the prestige of the court is no more than decades ago, it is also the court after all.

If his father directly rejected the emperor's request, Zheng Chenggong really didn't know how to deal with himself.

Therefore, he did not say anything to death, leaving room for maneuver.

"Well, I believe in Nan'anbo." Zhu Cixuan gave Zheng Chenggong a step forward and took the initiative to change the topic: "I heard that you were born in Hirado?"

Zheng Chenggong was stunned when he heard this and said subconsciously: "Your Majesty knows Hirado clan?"

He regretted it as soon as he said it.

The emperor is the one who asked him.

If you want to go into the deeper answer, it is very disrespectful.

Even if the emperor doesn't know, he can't say it out. If he knows, he must even shout that His Majesty is wise.

"You don't have to be surprised. Although I have never been to Japan, I have also seen the map. The Hirado family is a Japanese vassal."

"Your Majesty is wise. The student was indeed born in Hirado. He returned to Fujian at the age of six."

Zheng Chenggong thought about it and replied carefully.

Zhu Cixuan knew that during this period, Japan basically only did business with the Ming Dynasty and the Dutch. The Ming Dynasty was basically the Zheng family.

"I want to know what the ships from Nan'anbo to Japan are loaded?"

Zhu Cilang said half-jokingly.
