"Look carefully, this is the west, which can also be called Europa."

The first class this morning was Fang Xing, and the students were looking forward to his class.

Fang Xing often digress when giving lectures, but his mixed contents are very fresh, informative and addictive.

There was a big map hanging on the blackboard. Fang Xing talked with a whip in his hand.

"Do you think it's small when you look at Europa?"

The students below nodded one after another, which can be distinguished by the naked eye. Europa is not as big as Ming.

This is because Fang Xing counted the grassland into the territory of Daming, which must have at least 15 million square kilometers.

"Although it is small and there are many countries, it can not be underestimated."

"The Europeans are carrying out an innovation, ideological innovation."

Fang Xing's whip slid down to the sea. "What will this innovation bring? It will bring expansion, expansion for food, resources and slaves."

"At our feet is a big ball, which I have said, and on this ball, the land occupation is not large, more is the ocean."

The following students were listening attentively. Fang Xing's whip slid back and forth between the East and the West and said in a deep voice: "The expansion and communication are inseparable from the ocean. When we open the trade route to the western regions again with horses and camels, the Europeans will take away all the wealth that can be taken away in a big boat, hold a firegun, smile grimly, and drive people of other colors to mine and farm..."

"So we need the ocean!"

Fang Xing looked at the time and summarized: "Daming can't leave the sea, because wealth comes from the sea and danger comes from the sea. We can't avoid it, let alone close the door of the country. Then we have a dream of going to heaven until we are awakened by sabers and muskets."

After class, Fang woke up and walked out of the classroom slowly. Thinking of the word "strong boat and sharp gun", he moved in his heart and went to Jubao mountain guard.

When they arrived at the military camp, it was the time for practice in the morning. Lin Qun'an woke Fang up and welcomed him in. Looking at the smooth array of rotation, they couldn't help but feel happy.

Rotation speed is related to the output density of firepower, so it must be practiced, and often.

After waking up for a while, Fang went to the workshop when he turned to assassination practice.

The scale of the workshop is larger than before, but the manpower is still those.

Zhu Fang is taking the craftsmen to create a new type of flint gun. After the process, the finished products are supported on the side and look full of power and beauty.

"Can you build a gun?"

Fang Xing took out a drawing. It was a thick pipe with several hoops and a cross support.

Zhu Fang looked at the drawing and frowned: "uncle, but it's the same reason as a firegun?"

"Almost."

Fang Xing pointed to the muzzle and said, "first load gunpowder, then load iron balls, and finally ignite from the fire gate behind."

"I have to get a shelf."

Zhu Fang picked up the pencil pinned to her ear, drew a shelf below, and said dissatisfied, "it's still a little bad. The recoil force must be great. These shelves have to be taken into account."

Fang Xing doesn't worry about the gun rack. At Zhu Fang's level, it's not a problem.

"Take a closer look and see if you can make this kind of gun with iron."

Zhu Fang frowned and calculated on the paper. Only when she was half paid did she frown and say, "uncle, I'm afraid I can't use iron! I guess it won't be used many times."

Seeing Fang Xing's ignorant face, Zhu Fang quickly explained: "uncle, if you cast this gun with iron, there must be not much charge and range!"

"What about steel?"

Fang woke up and thought that the steel should be OK.

But Zhu Fang said with a bitter smile: "uncle, the steel is not stable, and if you cast a steel gun, the cooling process is not easy to control!"

This involves a professional problem. Fang Xing has no choice but to say, "try more here. If it doesn't work, bronze will do."

Bronze, also known as copper alloy, has good performance and is a good material for making cannons.

It's just that Daming is short of copper. Fang Xing is really moved by the cost of casting guns with bronze.

However, we must try, otherwise Daming lacks long-range strike firepower when facing the impact of the enemy group.

Small catapults are good, but the first is the lack of range. The second is that they can only throw pottery pots or cast iron bombs.

Think about the scene of artillery roaring. Iron balls rush out of the enemy's formation one by one. The visual impact will greatly reduce the enemy's morale.

Just do what you want. Fang woke up and hurried to find the military headquarters.

"Is Jin Shangshu there?"

The porter of the military headquarters said with a sad face: "Lord Shangshu is seriously ill."

what the hell!

Fang Xing had to step back and find Shikui.

"Copper?"

Shikui shook his head and said, "Xinghe Bo, copper material is not up to the lower officials. You have to find our Shangshu."

Yes! Fang Xing had to go to Jinzhong's house.

Jin Zhong's family looked very ordinary. After Fang woke up and announced his name, he waited for half the pay before someone came to meet him.

The housekeeper came to meet him. Looking at his expression, Fang woke up with a click in his heart. He thought that Jin Zhong wouldn't burp his fart!

If Jin Zhong farts when he comes to visit, his reputation will stink.

Oh, my God!

In the bedroom, there is a strong smell of medicine as soon as you go in.

Sitting at the head of the bed, Jin Zhong looks old and pale.

"I'm deeply infected. Xinghe Bo, please forgive me for my rudeness."

Jin Zhong's voice was a little weak. He pointed to the chair by the bed and began to breathe.

Fang woke up and sat down, pondered for a while, and finally said his intention.

"Copper?"

Jin Zhong frowned and said, "there are few copper materials in Daming!"

When Fang woke up to the documentary he had seen, he frowned and said, "Daming is short of copper, but Fang thinks there is still some copper for the gun."

"What's the power of the gun xinghebo said?"

"The range is less than a thousand feet. Using an iron ball is powerful."

Jin Zhong closed his eyes and thought about it. Finally, he said cautiously, "take some first. If it's easy to use, your majesty will naturally have an explanation."

"No problem."

Fang xingben just wanted to have a try first. Hearing the speech, he couldn't help feeling more favorable to Jin Zhong.

This man is not only Zhan Shi in Zhan Shi's house, but also ordered to assist Zhu Zhanji. It is reasonable that he should have a closer relationship with Fang Xing.

But Jin Zhong never took the initiative to meet Fang Xing, nor did he raise any opinions.

So this is the first time they've met.

Jin Zhong pondered for a moment, turned his eyes on Fang Xing, and coughed, "Xinghe Bo, it's not easy for sun. You often advised at that time."

Fang woke up and said, "why did Lord Jin say this?"

The conscience of heaven and earth, Fang woke up and felt that Zhu Zhanji was good enough. In addition to some love of beauty and some indecision, Zhu Zhanji was a qualified successor.

But Jin Zhong seems very dissatisfied.

"Don't let TAISUN become the target of public criticism!"

Jin Zhong breathed hurriedly. After slowing down, he continued, "isn't it better for TAISUN to hide his power and bide his time with the prince? You've attracted the anger of all the officials and the criticism of all the people!"
