Five gunshots later.
The bullet violently penetrated the goggles on the target, leaving five bullet holes.
This scene made Zheng Ci open his mouth in shock.
All the craftsmen who arrived were so surprised that their eyes widened and they felt incredible!
"My two highnesses, am I right?"
Zheng Ci rubbed his eyes and asked in disbelief.
He could really see that the protective mirror was pierced, and finally understood why His Majesty handed over both the Ordnance Bureau and the Gunpowder Department to Zhu Xuan and Zhu Song.
These things are definitely powerful military artifacts.
Their engineering department couldn't do it, but Zhu Xuan's factory could. There were only about two hundred people in the factory, so they pressed their engineering department to the ground and rubbed it.
"I'm ashamed!"
Zheng Ci said with admiration: "Before I came here, I thought that the two highnesses were just messing around. Now I realize that I am short-sighted and it is also the incompetence of our Ministry of Industry."
Zhu Song smiled and said: "Mr. Zheng, you're welcome. If our factory wants to develop, we cannot do without Mr. Zheng's support from the Ministry of Industry."
"Your Highnesses, please rest assured."
Zheng Ci changed his initial attitude, patted his heart and promised: "As long as I am still in the Ministry of Industry, whatever your Highness needs, I will definitely be able to provide it. I also ask Your Highness to make more weapons to protect the Ming Dynasty."
"I am very sure of that!"
Zhu Song affirmed.
After Zheng Ci was shocked, the craftsmen from the Ministry of Industry were also shocked. They relocated the Ordnance Bureau and the Gunpowder Department and moved everything to the factory.
Because gunpowder would explode and was very dangerous, Zhu Yuanzhang set it outside the city.
Even if it explodes, the impact will not be big.
The factory happened to be outside the city, which met Zhu Yuanzhang's requirements.
When the move was almost done, Zhu Xuan found Hou Xian, erected a blackboard in an open space, and started teaching classes. He first taught the physics and chemistry knowledge. Only after mastering the basics can he invest in research and development and production.
There are also experts in making firearms in the Gunpowder Department.
After listening to Hou Xian's description of firearm making, someone immediately asked some questions.
"Your Highnesses, how do you understand these things?"
Zheng Ci listened for a while. Although he didn't understand it very well, he thought it made sense and felt very novel.
Zhu Song had no way to explain, so he could only look at his nephew.
Zhu Xuan said: "These are the knowledge Hou Xian learned before, but they also come from sages."
"Sage?"
Zheng Ci frowned and thought for a while.
He didn't say he had memorized all the books of saints and sages, but he had basically read them all, so he was certain that there were none of them.
Zhu Xuan explained: "Hou Xian's knowledge will not be directly presented in the sages' books, but the sages have mentioned it. Zhuzi once explained things as things in the world, that is, all things in the world are due to their known principles. And to benefit the poor, to pursue it to the extreme. As for the long-term exertion, and once it is suddenly penetrated, the surface and interior of all things will be subtle and rough, and the overall use of my heart will be clear."
Zhu Xi is Zhu Xi.
Zheng Ci certainly knew about Zhu Xi's ideas and had studied them.
He was a little surprised that at such a young age, the little emperor's grandson could speak out Zhu Xi's great principles. But what did Zhu Xi's thoughts and ideas have to do with the knowledge explained by Hou Xian?
Zhu Song was confused when he heard it, but he was too lazy to delve into it. As long as it was useful, it didn't matter what his origin was.
"What Zhu Xi wanted to do was to gain knowledge by investigating the principles of affairs."
"The knowledge Hou Xian imparts in lectures is obtained by observing things. For example, rifles are obtained by observing existing firecrackers. The principles of rifles and firecrackers are similar, but rifles are better made than firecrackers."
"Aren't these consistent with what the saint said?"
"The source of knowledge is the sages. I have discussed it with Hou Xian. It is called studying things to achieve knowledge."
Zhu Xuan finally explained again.
The study of things to achieve knowledge has long been recorded in the Book of Rites, and Zheng Ci was no stranger to it.
However, he could also hear that Zhu Xuan just put the knowledge explained by Hou Xian into the shell of Zhu Zi and Gewuzhizhi, and gave a reluctant explanation.
Zheng Ci was surprised that a child could say these words.
But it didn't matter to Zheng Ci whether it was about studying things to gain knowledge, as long as he could make and improve weapons.
"The little emperor is right!"
Zheng Ci agreed.
They walked around the factory before Zheng Ci said goodbye and went back.
Zhu Xuan and Zhu Song had to stay and arrange everything, and then went to the Yangtze River to plan the location of a dock. If they wanted to get a piece of land by the river, they had to go back and discuss it with Grandpa Huang.
But there is no need for the shipyard to rush. Let Hou Xian build the steam engine first, and then consider how to implement it.
Now there are craftsmen from the Ministry of Industry joining. They have a certain mechanical foundation and should be able to help him turn these into reality.
It was not until evening that they returned to the city.
Zhu Song is going to take a trip to Daming Bookstore to take a look at the recent situation and arrange the next market development work, expand to other places, and continue to open branches.
Zhu Xuan returned to the palace.
Thinking of what he said to Zheng Ci today, Zhu Xuan held his head and thought for a long time, sorted out his words, and wrote an article on studying things to gain knowledge, and even related the article to physical chemistry.
This kind of scientific content, combined with Confucian thought, brought a little shock to the people of the Ming Dynasty.
Time flies quickly, another half month has passed.
Yan Guan came back and said that Zhang Sanfeng could not be found at all.
Jin Yiwei had been to Wudang Mountain, but he was not there at all.
Those Wudang disciples didn't know where Zhang Sanfeng had gone. He was probably traveling around the world.
However, Liu Chun was still found and agreed to come back with them. He was in Zhenfu Division.
"Mr. Liu, please come to Daming Bookstore!"
Zhu Xuan said and went out of the palace to the Daming Bookstore.
After a while, a man in his thirties appeared in front of him.
"Greetings to Your Highness!"
When Liu Chun saw Zhu Xuan, he didn't understand.
What's the matter with such a young grandson of the Ming Emperor finding himself back?
Zhu Xuan was also sizing up the other person. According to the investigation results, Liu Chun was already thirty-four years old, but he looked about the same as twenty-four years old. He was well-maintained and was a person who was proficient in health preservation and knew how to prolong life.
"Mr. Liu, you're welcome."
Zhu Xuan was also unambiguous and said directly: "Your Majesty is getting older. Although he is still very powerful and strong, he will get older and older one day. I heard that Mr. Liu has superb medical skills and is better than the emperor in the palace." Doctor, I just want to invite you to come back and nurse your grandfather back to health."
Liu Chun suddenly realized that it was because of these things and admired him: "Your Highness is extremely filial!"
The young grandson of the emperor already knew how to be filial, but after considering it in the end, he still refused, shaking his head and saying: "I can appreciate your highness's filial piety, but my ambition is to practice medicine to save the world and save the world. The Ming Dynasty also has There are many people in need of treatment, and I cannot ignore them. Your Majesty is the lord of the world, and there are many doctors in the palace. There are countless doctors who are better than me, so they may not necessarily need me."
Zhu Xuan would not doubt the authority of the imperial physician in the medical field.
But in terms of health preservation, Zhu Xuan believes that no one is more proficient in this than Liu Chun, who has lived for more than 120 years.
