"Really? Your Highness."

When Wang Chong heard this, he immediately felt energetic.

The two came to the yard dedicated to Wang Chong in the Military Affairs Office.

On the stone table in the yard, he spread the drawings out.

"In addition to artillery, I am preparing to build these firearms. The principle is similar to artillery, but it is much smaller and the soldiers can hold it in hand." Zhao Xu said, pointing to the flintlock rifle on the drawings.

This was drawn by him.

Wang Chong's eyes were staring at the things on the drawings, and he was very shocked.

Although this is just a picture, he could imagine how gorgeous it could be after it was made.

"Are you really responsible for creating this?" Wang Chong's excited voice changed.

When he entered the Military Affairs Office, he had not completed anything independently, and he made some small accessories.

Zhao Xu shook his head, "No, this kind of firearm involves multiple processes. What you are going to do now is this part of this firearm, the firing device."

Wang Chong's smile froze. He was still only responsible for part of it.

"Your Highness, the official wants to make this thing independently."

Looking at the drawings, Wang Chong's eyes were full of begging.

Zhao Xu shook his head, "It's not that I underestimate your ability, you can't do it."

Just like the popular saying in the contemporary era, the principle of nuclear bombs is open to the world.

Why are only a few countries able to independently create nuclear bombs?

It can be seen that behind an achievement is a strong industrial system that needs to be supported by, not something that can be created.

In the era of pure agriculture in Dasong, the industrial foundation was almost zero.

So before building artillery, he must first solve the problem of iron and steelmaking.

Then there was the issue of artillery mold. Only when these two were complete can the Military and Military Affairs Office have the ability to create artillery.

In contemporary times, the flintlock rifle was born in Europe in 1547 and was then equipped for two hundred years.

But the flintlock rifle was built during this period because its fine watch industry was already very prosperous.

Have the ability to make fine accessories.

The same goes for it.

The three problems of flintlock rifle, barrel, firing device and flint in Yanzhou need to be solved so that the manufacturing can be smooth.

In this problem, he planned to drill out the barrel directly with cast iron parts to solve the problem of the barrel blowing and the uneven inner wall weakening its power.

But in this way, you have to first get the hydraulically driven drilling machine.

The firing device is the core component of the flintlock rifle.

The flint is clamped on the firing device and pulls the trigger. The flint falls, hits out sparks and ignites gunpowder.

The structure of this component is relatively complex and has a spring wheel structure.

What he wanted Wang Chong to do was to make this thing wholeheartedly.

As for flint to be relatively simple, the fire sickle used by the ancients required flint to shoot out Mars to ignite. Many of the smooth stones at the bottom of the river were.

The above requires multiple craftsmanship, so he said that Wang Chong could not do it alone.

Even if he does it alone, it will take a lot of time.

The most important thing is that the firing device is not made by imitating drawings.

The steel required for the spring wheel structure requires spring steel.

"Your Highness, do you still don't trust your subordinates?" Wang Chong felt even more aggrieved and refused to give up.

Zhao Xu remembered that Wang Ying said that Wang Chong was complacent because of some small achievements during this period.

So he chuckled twice, "Then you make this firing device first, and I will give it all to you."

"Yes, Your Highness." Wang Chong was happy.

After giving this order, Zhao Xu returned to the royal palace.

At the gate of the palace, he saw a carriage.

The carriage was hung with bead curtains, and the inside was a red curtain, which was obvious to the carriage for my daughter's house.

With a hint of doubt, Zhao Xu entered the palace.

I saw Xu E standing in the middle of the yard, smiling at herself.

"Miss Xu." Zhao Xu shouted.

When Yancheng was besieged, he heard Feng'er say that Xu E and the people from Tianxianglou helped to guard the east gate.

He was going to come to thank him, but he forgot about it for a lot of things.

"Your Highness." Xu E lowered her body and blessed her with a hint of reluctance in her joy.

During this period, she witnessed the growth of the King of Yan from a crazy prince who even looked down upon by the Zhang family to a vassal king who could not be ignored and held the power of the four counties.

But the more noble the King of Yan was, the more she felt the distance between herself and the King of Yan.

"Your Highness, I am ordered to meet the capital, so I came to say goodbye to you."

Zhao Xu was about to speak, but Xu E said.

"Miss Xu is leaving?" Zhao Xu was stunned for a moment, feeling a little disappointed.

After all, Xu E has helped him a lot during this period and has ambiguous warmth.

Xu E nodded, "Tianxianglou was in Yanzhou to help Your Highness and fight against the Yuan family. Now the Yuan family has suffered heavy damage and is no longer a rival to Your Highness. Tianxianglou has no need to be in Yanzhou."

Upon hearing this, Zhao Xu said, "Since that's the case, can't we tell who the owner of Tianxiang Tower is?"

Xu E nodded, "This time, when I came to the royal palace, I came for this matter, in addition to saying goodbye, the owner of Tianxianglou is actually the old friend of Your Highness."

"Old friend?" Zhao Xu was slightly surprised.

Xu E chuckled, "Your Highness, remember Princess Changle!"

"Princess Changle!" Zhao Heng was shocked when he heard this.

The Princess Changle was originally named Nian Yujiao. After being adopted by King Chun as her adopted daughter, she changed her name to Zhao Yujiao.

His father Nian Heng was born into a poor family, but because of his outstanding talent, he became the Minister of War.

This is rare in Dasong.

Five years ago, when Zhao Xu was not crazy and stupid, Zhao Heng made a sudden idea and asked Zhao Xu, who was not crazy and stupid at the time, to enter into a marriage contract with Nian Yujiao.

After all, princes from other power tribes are disdainful to marry Nian Heng's daughter.

But the good times did not last long. The following year, Nianheng was collectively impeached by officials of the powerful clan and falsely accused of corruption of hundreds of thousands of taels of military pay.

Immediately, Nian Heng was killed by Qiu Ji.

Nian Yujiao's mother was too sad and died within three months.

At this time, Princess Chun came forward and adopted Nian Yujiao.

When Zhao Heng's mother Mi found out, she voluntarily quit the engagement.

After all, Nian Yujiao is already Zhao Xu's cousin in name.

"I didn't expect it was her? It's just a weak woman. How could he have such skills? It's really surprising." Zhao Xu's mood was ups and downs.

Xu E did not answer, but said, "Your Highness can trust me now."

Zhao Xu nodded and shook his head again.

Although he and Nian Yujiao had had an engagement, they had only met several times and could not have had any friendship.

Nian Yujiao's Tianxiang Tower was definitely not built for him.

Moreover, he didn't believe that Nian Yujiao could establish such an intelligence network that could be founded on Dasong.

After thinking about it, he said, "I'm afraid there is someone behind Princess Changle, so it must be King Chun!"

Recalling the arrival of the silly King Chun who brought military supplies to Yancheng, he couldn't help but feel cold behind him.

The water in Dasong seems to be deep.

"I don't know this. I am only sent by His Highness the Princess." Xu E refused to admit it directly.

Zhao Xu stared at Xu E, "If you tell me about this, they must be prepared to reveal their identities. Aren't they afraid that I will stab the court?"

"I was not sure before, but the emperor gave Yuan Li gently and ordered the Yuan family to check and balance His Highness, and the princess was sure that His Highness would not betray her." Xu E also looked directly at Zhao Xu, "The princess also asked me to give him a word."

"What do you mean?" Zhao Xu tried hard to recall Princess Changle's appearance, but it seemed that it was always blurry.

"The emperor's favorite is always his own. He did this twenty years ago, four years ago, and will be like this in the future. I just hope that Your Highness will do it." Xu E said slowly.

Zhao Xu was stunned for a moment. Twenty years ago, it was the time for Zhao Heng to ascend the throne.
