Become a feudal king from today

"It's much easier to conquer Xiliang. What I'm afraid of is that this is just a bait for Beidi." Zhao Xu frowned.

Although Beidi is Da Song's mortal enemy, he has to admit that Beidi's operation is very shrewd.

This is simply the same pattern as the contemporary United States inciting small countries to challenge big countries and engage in proxy wars.

Now that Xiliang had successfully angered Da Song, his father and the Manchu civil and military officials unanimously decided to send troops.

There is no doubt that the northwest of Dasong will become a meat grinder between the Three Kingdoms.

After all, as long as Dasong goes to war with Xiliang, the Beidi people will definitely end up in trouble.

"It's just that the emperor has made up his mind. Even if Beidi participates, this war is probably unavoidable." Chang Wei frowned, then relaxed, "But fortunately we don't need to send troops this time."

Liu Fu nodded, also secretly happy.

Now he and Chang Wei just want to guard this three-acre land in the four counties.

Don't care about the others.

Chang Wei continued: "But Beidi is currently developing a fire bomb. Even so, we must be careful during the Northern Expedition. The Black Iron King's tent has always been restless."

Zhao Xu deeply agreed.

"It seems they are very confident in their bronze cannon." Zhao Xu sneered.

Xu Ke told him about Beidi asking for bronzes from Xiliang.

He thought for a moment and guessed that Beidi made bronze cannons.

If the missionary from Russia knew only this kind of artillery, he would be relieved.

Because compared to iron cannons, bronze cannons have a very low technical content and rely only on the ductility of bronze materials.

The iron cannon and steel cannon test the steel smelting ability.

This is the basis of industry.

At the same time, the shortcomings of bronze cannons are significant.

A very expensive one.

Dasong belongs to a copper-poor country, and copper is hard to come by. This will severely limit the number of artillery made in Beidi.

Secondly, bronze conducts heat quickly and cannot achieve rapid fire like wrought iron cannons.

In this way, you won't be able to take advantage in a war.

It cannot be mass-produced and has a slow rate of fire. These two points are outcompeted by his artillery.

What's more, his artillery has been cut and its range has been improved than before.

"Humph, the artillerymen of the royal family will teach them how to behave." Chang Wei raised his eyebrows.

"In this case, we just need to follow the emperor's order and guard our four northern counties." Zhao Xu said.

Thinking of something, he asked again: "How is the bayonet of the flintlock gun equipped?"

"Eighty percent of the soldiers are equipped with equipment, and there are still 20% left to finish." Mentioning this, Chang Wei felt excited.

In this way, the advantages of the flintlock gun will be fully utilized in the war.

Zhao Xu looked satisfied.

The bayonet is very simple to make. After all, with the hydraulic forging hammer now, it is very simple to train the weapon.

He told Chang Wei.

Zhao Xu said to Liu Fu again: "The development and construction of Yanzhou cannot be stopped, you have to continue to keep an eye on it."

"Yes, Your Highness." Liu Fu responded.

The two were ordered to go back, and Zhao Xu continued to write his own "Naval Training Manual".

At this time, Wang Ying suddenly ran in with a hurried look, his face pale.

Feng'er panted and followed Wang Ying, scolding: "Master Wang, how could you break into the palace without permission?"

The servant said that Wang Ying arrived at the gate of the palace and barged in without waiting for notification.

Wang Ying looked like he was about to cry.

He apologized to Feng'er first, and then said: "Your Highness, something happened to Wang Chong."

"What's wrong?" Zhao Xu asked. When he saw that Wang Ying was not in a good state, his heart sank immediately.

"Wang Chong him, he flew away." Wang Ying stammered.

Feng'er burst out laughing, "Master Wang, you are just joking. Can Wang Chong still fly?"

Wang Ying grimaced, pulled Zhao Xu and walked out, "Your Highness, if I don't lie to you, I'm in heaven!"

Zhao Xu was dragged outside by Wang Ying. He followed his hand and looked up, suddenly breaking into a cold sweat.

I saw a huge spherical object floating in the sky at this time, which seemed to be burning with flames.

Someone can still be vaguely seen above.

This thing is nothing else but a hot air balloon.

He went to the study and picked up the telescope and looked up. Sure enough, the person standing above was Wang Chong.

At this moment, Wang Chong seemed to be panicked and kept shouting something on the hot air balloon.

But because the distance was too far, they couldn't hear it at all.

At this moment, the palace servant informed that students from the Science and Technology School, accompanied by guards, asked to see him.

He immediately ordered the students to come in.

"What's going on!" Zhao Xu got angry at the students for the first time.

The three students all shrugged their heads, and one of them said: "Your Highness has attached great importance to Qu Sheng and others who are good at chemistry during this period, and has neglected those like us who are good at physics. Wang Chong then came to the three of us and said that we were going to come up with something. Something awesome, a surprise for His Highness.”

The student on the left added, "His Royal Highness said that air will rise when heated. This is the principle of a hot air balloon. He also drew the structure of a hot air balloon in the textbook, so Wang Chong decided to build a hot air balloon."

"We couldn't leave the school without permission, but Wang Chong was an official of the Military War Department and could come and go freely. So he found someone outside to sew the balloon of the hot-air balloon. Today, he was supposed to test it secretly. Unexpectedly, the rope was not fixed properly, and the hot-air balloon was heated. The balloon flew away." The student on the right shrugged his head.

"You guys are too courageous." Zhao Xu pointed at the three students and raised his hand to hit them. The three of them shrank in fear.

However, he still stopped his hand. He could not curb this desperate technological exploration.

Otherwise, it will be difficult for real talents to appear in the four northern counties.

But in this case, it is really unknown whether Wang Chong can still be alive.

"Follow me and chase after him." He immediately ordered horses to be prepared and went after Wang Chong's hot air balloon.

The earliest contemporary record of a hot air balloon was in 1782, which was in the 18th century.

At that time, the hot air balloon was sewn with numb washi paper.

The fuel is straw and wool, and when flying, a cage is hung below, with chickens, ducks and sheep stuffed inside.

The balloon flew to an altitude of 450 meters and stayed in the air for eight minutes.

The performance was visited by King Louis XVI of France at the time.

According to the students, Wang Chong's fuel was straw mixed with lamp oil, so he shouldn't be able to fly far.

Now I just hope that this hot air balloon can land smoothly.

Otherwise, Wang Chong is really going to ascend to heaven.
