Hearing Zhu Zhanji say this, Zhu Di asked excitedly: "Is Ji'er willing to lead the army?" ”

The most difficult thing about the musket of the Ming Dynasty was the manufacture of the barrel. In this era, holes could not be drilled, and the barrels were hammered out by craftsmen, and for safety, they had to be made into double layers, which also made the manufacture of muskets not only slow, wasting labor, but also unsafe.

Zhu Zhanji nodded and said, "But there are a few conditions for my grandson. ”

Zhu Di's face turned pale, glared at him and said, "You still have to negotiate terms with me?" ”

Zhu Zhanji said: "Grandpa Huang, if you want your grandson to do things, you must give your grandson some people!" Without craftsmen, how do you let your grandchildren do things? ”

Zhu Di snorted and said, "Then you can tell me your conditions!" ”

Zhu Zhanji thought for a while and said: "My grandson wants a lot of people, from miners, ironsmiths, blacksmiths, craftsmen, and then hundreds of craftsmen in the Ministry of Industry, each of which needs a few skilled people, it doesn't matter if you are older, the key is to be experienced." ”

"If I have allowed this, you will be able to make a musket?"

"The grandson hasn't finished talking yet, the grandson still has to burn charcoal, and the potter ......"

Zhu Di listened impatiently, interrupted him and said, "I will give you whatever you want, and you can make a musket?" ”

Zhu Zhanji said with certainty: "Sun Er not only has to make muskets, but also makes better artillery. ”

The cannon of this era is actually simpler, and the key is the improvement of material technology and casting process.

The casting and pouring process of the Ming Dynasty is actually very good, and the bell weighing several tons can still be engraved with fine patterns and patterns.

The key is the material process.

Now the most important thing is to make qualified machine tools, as long as there are machine tools, the entire Ming industry can have a qualitative improvement.

There are two parts of a lathe, or machine tool, that are difficult to solve with today's level of technology.

The first is the power part, without electricity, without a motor, it cannot provide a stable power output.

The second part is the material part, in order to manufacture high-strength alloy cutting tools that meet the requirements, it is necessary to improve the material process from the steel plant, and this requires countless tests to obtain qualified materials.

Only by solving these two problems can the machine tool really play its due role.

The first problem to be solved, Zhu Zhanji already had a draft, Nanjing is close to the Yangtze River, and only needs to build a waterway to rely on water power to provide power.

The most difficult thing to solve here is the power strength and transmission part of the waterwheel, but as long as the bearings are manufactured, the waterwheel can be built larger, and the power part is not a big problem.

However, in terms of material technology, Zhu Zhanji knows that tungsten steel is the best way to make cutting tools, but he doesn't know how much material to match.

Tungsten steel may not be easy to solve in other countries because tungsten ore reserves are not much. However, China happens to be the world's largest tungsten mining country, and today's Nan'an Province, which is later Dayu County, is the world's largest tungsten capital.

For Zhu Zhanji, who is familiar with the distribution of global mineral resources, if he wants to obtain high-strength tungsten alloy steel, he only needs to find an excuse to let people develop tungsten ore there.

Mixing molten steel in a furnace by the miners always makes alloy steel that is harder than ordinary steel.

The key is the excuse.

Without a suitable reason, Zhu Zhanji said that there is tungsten there, which can make high-strength alloy steel, then he is not a grandson, but a god.

Again, for this reason, he has not yet come up with a cement formula.

However, cement is a sharp weapon, and he is ready to hand it over to Madi to invent. This little guy has the curiosity and associations that a scientist should have, and is good at daydreaming.

For example, from Zhu Zhanji making scooters, he can think of ice skates; The transmission system of the lathe, he can associate it with a bicycle.

Zhu Zhanji talked to him and was often taken into the ditch by him, but many of his wonderful ideas were indeed very probable.

For example, he used a 40x telescope to see the moon, but he still couldn't see it very clearly, so he wanted to study a telescope with a higher magnification.

Zhu Zhanji reminded him that he could not only look far away, but also look small, so he used several convex lenses to make a simple microscope.

Although the things that have been made are still very rudimentary, now that the door has been opened. Zhu Zhanji believes that as long as he tastes the sweetness, he will have the driving force to promote the development of science and technology.

Madi didn't like to be clean before, often wiped his nose with his sleeve, and didn't wash his hands when eating. But when he saw a layer of wriggling germs on his arm, he suddenly became cleaner than anyone else.

Zhu Zhanji originally planned to wait for the Chinese New Year to sell the microscope to Tai Hospital. He was also going to let Ma Di go home, let him move his own home, and let his father open a few glass kilns and porcelain kilns in Xiamaqiao, and at that time, get the cement out.

Although Ma Zhicai does not have Ma Di's whimsy, he is an excellent craftsman. In just one month, he solved the problem of the steel ball circlip of the bearing, so that the steel ball will no longer run around.

Under the leadership of the young army's Bingzi Company, a group of little guys, they simply filed dozens of gears by hand and made this simple lathe.

He may never be an inventor, but being an engineer is still no problem.

Zhu Di confirmed again: "I can give you whoever you want, can you be sure that you will produce muskets in large quantities in the future?" ”

Zhu Zhanji said with a smile: "Grandpa Huang, rest assured, my grandson never fights uncertain battles." ”

Zhu Di glanced at him obliquely, waved his hand, and all the eunuchs and cabinet scholars, including the brocade guards who were guarding, immediately retreated.

Ma's uncle and nephew had never experienced this scene, and they were a little dumbfounded at this time, seeing Zhu Zhanji waving his hand at them, he immediately turned around and walked out.

This is actually a big disrespect, and you can only turn around and leave the house facing the emperor. But at this time, Zhu Di didn't care about the uncle and nephew, not to mention that he also had a bit of a love for talent, so he didn't care.

When there were only two grandchildren left in the warehouse, Zhu Di opened his mouth and asked, "So, you also regard your second uncle as an enemy?" Never fight uncertain battles...... Are you sure you can win this time? ”

Zhu Zhanji said solemnly: "The victory or defeat is all in the emperor's grandfather's thoughts, and I did this just to give the emperor's grandfather an excuse to solve the worries of the Ming Dynasty." ”

Zhu Di didn't expect Zhu Zhanji to admit it directly, so he was stunned for a moment and sneered: "So, you still think about me." ”

"The grandson doesn't dare to take credit."

Zhu Di laughed angrily, pointed at him and scolded: "Bastard! Today you have to say that you don't accept me, see that I don't serve me! ”

Zhu Zhanji said with a smile: "The Ming Dynasty has worked hard for two generations, and the national strength is thriving. After Meng Yuan withdrew from Monan, Beiyuan actually no longer had the strength to compete with my Ming Dynasty. Two northern expeditions, the first crippled the Tatars, and the second crippled the Warats. Now that Wu'an Hou is guarding Beiming Mountain, it will become a nail that my Ming put in Beiyuan. When the copper mountain mining is more prosperous, the grassland will become the heart of the Ming Dynasty in the future, whether it is the Warat people or the Tatars, they will only choose to help me the Ming herding horses, or mining to survive. ”

Zhu Di was a little overjoyed, Zhu Zhanji said what he was proud of, so he couldn't help but nodded, but then remembered that he was asking for guilt in Xingshi, and showing such an attitude at this time didn't it make this kid even more proud.

So he mumbled and said, "Don't talk about these useless things. ”

Zhu Zhanji was secretly amused in his heart, cleared his throat and said: "My Ming Dynasty's national strength has risen and its territory has expanded, at this time, it should be to concentrate domestic forces and expand externally, but the country's instability has affected the progress of the Ming Dynasty's territorial expansion. My father is in poor health, and you have pity on his body, so you do not trouble him with mundane things. But Uncle Han thought that you were dissatisfied with him and coveted the great treasure. This competition can certainly exercise his talents, but I am afraid that I will become the second Uncle Wei. ”

Zhu Di did not recognize Emperor Jianwen, and during the four years that Emperor Jianwen was in power, after he ascended the throne, it was all counted on Zhu Yuanzhang. For example, in the first year of Jianwen, he asked the historian to record the thirty-second year of Hongwu, the fourth year of Jianwen, and the thirty-fifth year of Hongwu.

Therefore, when Zhu Zhanji mentioned Zhu Yunwen, he was not commensurate with Emperor Jianwen, but just called him Uncle Wen according to the genealogy.

Zhu Di asked, "Are you afraid of your Uncle Han?" ”

Zhu Zhanji smiled and said: "Uncle Han Wang is brave and unscrupulous, and his grandson has never cared about him. ”

"Then why do you say you're afraid of becoming the second Yunwen?"

Zhu Zhanji sighed and said, "I'm afraid that I will take over the throne directly from you like Uncle Wei." ”

This time, Zhu Di understood, and for a while, his face became a little stiff.

Zhu Zhanji said again: "That day, my grandson got my grandfather's will and took the power of the water division. This would have been a happy thing, but the grandson was not happy. When my father heard that his grandson was in power, he was so angry that he fainted, and although he woke up, he was weak and his heart was like ashes. His health is not good, and Uncle Han Wang has been aggressive, and his grandson is afraid that if this continues, his days will not be too long. ”

"Say no more...... I understand ......"

Zhu Di interrupted him, walked out a little gloomily, and walked to the door of the warehouse, he turned around and said, "I think you are worried about your father this time, and I won't pursue it this time." But...... Ji'er, you have to remember that this world is our Zhu family, and the people of the Zhu family can't have civil strife at any time, let alone draw swords against each other! ”

Zhu Zhanji nodded, and then he continued to walk out, and the tall figure was also a little stiff.

Having said that, Zhu Zhanji did not think so. If you can't draw your sword against each other, then how did you get your throne?

At this time, Zhu Zhanji said loudly: "Grandpa Huang, grandson is not greedy for the throne, for grandson, those mysterious places outside the Ming Dynasty are actually more attractive to grandson." ”

He turned around again and said, "As a descendant of the Zhu family, you have to bear the responsibility that belongs to you!" ”
