In fact, there is a record of the production method of granulated gunpowder in the "Wubei Zhi":

To make gunpowder, each material uses five catties of nitrate, one catty of yellow, and one catty of eggplant ash. The above nitrate, yellow, ash a total of seven catties, divided into three troughs, fixed grinding 5,500 degrees, out of the trough. Three catties of each medicine, one catty of good soju, into mud, still in the trough, and then grind hundreds of times, out of the trough. Mix into grains, such as the size of yellow rice or mung bean, and it must be put into the palm of people's hands without feeling the heat.

It is a pity that this granulated gunpowder was not recognized by the imperial court in history, and the official black powder was still in powder form.

Of course, Zhu Cihong wants to change this status quo.

He wrote down the method of making granulated gunpowder, handed it to Gao Hongtu and said: "Da Sikong asked the people under him to make gunpowder according to this method, and they can meet my requirements."

Gao Hongtu took the granulated gunpowder formula with trembling hands, how could His Majesty the Emperor of the Heart Dao know about such a thing?

Daming produced a carpenter emperor, isn't there also a medicine emperor?

No, no, no, the idea is terrible.

Gao Hongtu shook his head continuously.

It must be a God-given method. Your Majesty is the Son of Heaven, and God himself has to pass it on to him.

"The old minister respectfully obeys His Majesty's orders."

Zhu Cihong is 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. The so-called diligence can make up for clumsiness, as long as he can do a good job of the firearms department according to his own will, it will not be in vain for Zhu Cihong to trust and delegate power.

"There's one more thing to be aware of. This method of making granulated gunpowder must not be leaked out, and if I know who leaked the formula, the law of the country will not forgive it! ”

Granulated gunpowder can be used in a wide range of applications, not only with firearms, but also to make explosives packs. Although the explosive performance of black powder is not as good as that of chemical powder, it can still exert good power as long as it is used properly.

Neither Li Zicheng, Zhang Xianzhong nor the Manchu Qing Dynasty had mastered the preparation method of granulated gunpowder, which was a major advantage of the Ming Dynasty. Of course, Zhu Cihong does not want this advantage to be lost due to artificial reasons.

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

After explaining this, Zhu Cihong left the Ministry of Engineering and moved to the Huangming Military Academy.

On the one hand, he wanted to see the recent study of the students of the military academy, and secondly, he wanted to meet Zheng Chenggong alone.

Not long ago, Zheng Zhilong replied to the letter, expressing his firm support for the idea of the Emperor Ming Trade Chamber of Commerce.

Although Zhu Cihong understands that relying on the Zheng family to go to sea is not a long-term solution. But right now, Zheng Zhilong must be used.

Zheng Chenggong is undoubtedly the most important trump card in Zhu Cihong's hands. Although Zheng Zhilong is selfish by nature, he will not deny his relatives until he is forced to do so.

After coming to the Huangming Military Academy, Zhu Cihong cordially greeted the students studying at the Military Academy.

There are two main parts of the student composition of the Huangming Military Academy, one is the sons and nephews of the warlord leaders, and the other part is the young talents collected by Zhu Cihong according to his understanding of history.

Such as Zhang Huangyan, Lu Xiangguan and others are worthy of good training. Zhu Cihong firmly believed that these people could seamlessly transition after graduating from the Huangming Military Academy and be directly assigned to serve as officers in the Shence Army.

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

The content of this part was naturally written down by Zhu Cihong, and then compiled into a book by a special scribe.

In this way, Zhu Cihong can ensure that military cadets are exposed to the purest military theories.

When the Son of Heaven came, everyone was very nervous, and Zheng Chenggong was naturally no exception.

Especially since the Son of Heaven had to summon him alone, which made him take several deep breaths before calming down.

"I came today to ask, is what Nan Amber said in his reply to the letter true?"

"Your Majesty, what my father said is true. My Zheng family is willing to die for Daming! ”

Zheng Chenggong was not stupid, he understood that the emperor asked him these words to be tempted.

Although he understood that his father's verbal promise was good, and that he might hide his secrets for various reasons in practice, at least he could not hesitate in the slightest when making a promise to the Son of Heaven.

As for my father, I can only persuade him.

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

Zhu Cihong mentioned it without being salty.

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

"I intend to let him be in charge of the trade affairs of the Huangming Trade Chamber of Commerce in the Minhai generation, so that Nan Amber can concentrate on coastal defense."

Zhu Cihong put forward this idea after careful consideration.

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

From this, it can be seen that Zheng Hongkui still has a bottom line.

Zhu Cihong didn't need Zheng Hongkui to be on the side of the imperial court. He only hoped that this person could take away some of Zheng Zhilong's power. In this way, even if Zheng Zhilong really gives birth to two hearts in the future, it will not be completely unmanageable.

"It's... Your Majesty didn't know that the fourth uncle of the student had always followed his father to praise military affairs. However, the student believes that his father must be able to understand the painstaking efforts of the imperial court. ”

The stakes are very high, Zheng Chenggong couldn't answer Zhu Cihong directly, so he had no choice but to make up a reason to deal with the past first.

Because no one knows better than him, his father is a master of military power and financial power.

If the imperial court sent a person to Fujian to concharge the affairs of the Huangming Trade Chamber of Commerce, he would definitely be strongly resisted by his father. But what if this person is replaced by his own uncle?

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

Although the prestige of the imperial court is not as high as it was a few decades ago, it is also the imperial court after all.

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

It was because he didn't say it to death, leaving room for turnaround.

"Well, I believe in Nanamber." Zhu Cihong gave Zheng Chenggong a step down and took the initiative to change the topic: "I heard that you were born in the Hirado Domain?" ”

Zheng Chenggong was stunned when he heard this, and subconsciously said, "Your Majesty knows about the Hirado Domain? ”

As soon as the words came out, he regretted it.

It was the Son of Heaven who questioned him.

If you want to dig deeper, it is very disrespectful to answer yourself.

Even if the Son of Heaven doesn't know, he can't say it. If you know, you should shout your majesty's wisdom.

"You don't have to be surprised. Although I have never been to Japan, I have seen the map. The Hirado Domain is one of Japan's great feudal clans. ”

"Your Majesty is wise, and it is true that the student was born in the Hirado Domain, but at the age of six he returned to Fujian at the request of his father."

Zheng Chenggong thought about the wording and replied cautiously.

Zhu Cihong 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 in this regard.

"I want to know what the ships that go to and from Japan are loaded on?"

Zhu Cihong said half-jokingly.
