Li Chen'an sat in the Ordnance Department for most of the day.

For lunch, he instructed Amu to ask the imperial chef to send a few hot dishes and soup to eat here.

Of course, Huang Xiumu also stayed here.

He looked at the regent who was squatting at the table, eating with these craftsmen dressed in soot, and his heart was extremely shocked.

Similarly, Zhao Sanmu, the head of the Ordnance Division, never expected that this young regent would be so casual.

Li Chenan didn't realize that his current status was frighteningly high, he just felt that these craftsmen were very kind, and he felt that such people could be called the soul of Ningguo!

Their comprehension is extremely high, and their attainments in smelting are also extremely high.

When they put forward some opinions about the flint cannon, they quickly grasped the mystery -

In fact, Li Chenan didn't know the casting method of fire and cannon, he just said some key points based on the shallow knowledge of his previous life.

For example, it is obviously not possible to use bamboo to make a cannon barrel, because it can't stand the explosive force generated by fire and medicine, and it must use an iron cannon, which involves the manufacture of molds.

These craftsmen soon came up with a plan, using yellow clay to mold and water molten iron to cast the barrel.

When Li Chenan mentioned that if rifling could be engraved in the barrel of this cannon, the cannonball would be used as a bursting shell, they quickly came up with a way to do it.

Then the pattern is engraved on the mold, which needs to be extremely fine, so that the so-called rifling in the poured barrel will be more uniform, so as not to affect the flight path of the projectile.

Wait a minute.

Of course, there are still some issues that have not yet been resolved.

For example, how the shell exploded and exploded again after it was fired.

For example, how thick the iron cannon needs to be poured to withstand the force of the explosion and the explosion of the charge, etc.

Li Chenan didn't know these things, so he had to leave them to summarize experience in the experiment to improve.

Now the main task given to them by Li Chenan is...... Make fireworks!

This thing is cheap and good, and it is a rare weapon on the battlefield.

Of course, fireworks can be detonated in a variety of ways, Li Chenan proposed the concept of delayed detonation.

He didn't know how to do it, but he believed that the wisdom of the people was infinite, and sooner or later they would be able to figure it out.

These craftsmen listened to Li Chen'an's whimsical ideas, and they were suddenly shocked.

After all, this is something that has been thousands of years ahead of this world, and although it is all a little skin, to them, this is already the great wisdom of the regent!

So, when they looked at the young regent again, their eyes were no longer filled with fear, but with deep admiration!

He's a poet!

Who has ever heard of such a literati still understands such profound knowledge!

Huang Xiumu's eyes were full of stars, and Zhao Sanmu's eyes were as bright as lotus flowers.

"Don't worry, Lord Regent!"

Zhao Sanmu poured Li Chenan a cup of tea, "Xiaguan must live up to the regent's expectations, give priority to the production of fireworks, and start the cannon experiment according to the regent's wishes!" ”

Li Chenan took a sip of the teacup and nodded, "I'll leave these things to you next!" ”

"This is the most important weapon of the country!"

Li Chenan's expression became serious, and his tone became a little heavier:

"I want you to understand how important it is!"

"Everyone here, everyone who will be involved in the future, must be kept secret about this...... If there is a leaker, the nine clans should be punished! ”

Zhao Sanmu looked at the six craftsmen, and one of them knelt down, "The villain knows that it is powerful, please rest assured that the regent will die...... I will never leak half of it! ”

"Good!"

Li Chenan stood up, walked over, and helped the six people up one by one.

"Of course I believe in you, for the sake of security, from today onwards, your and other family members will also join this armory......"

"Lord Zhao,"

"The lower official is here!"

"You are responsible for arranging the accommodation of their families, and not allowing their families to be wronged in the slightest, if there are children in the family who go to school...... I'll go to the Guozijian to say hello and let their children study in the Guozijian. ”

"In addition, there are not enough of the six of them, the Ministry of Industry needs to recruit more craftsmen who are proficient in various skills, one should be treated preferentially, don't worry about the silver, in two days, Li Wenhou, the head of the household, will send silver to the Ministry of Industry!"

Huang Xiumu and Zhao Sanmu clasped their fists and saluted: "Respect the regent order!" ”

"You guys are busy, if there is anything that needs to be coordinated, come to me as soon as possible."

Li Chen'an left the Ordnance Division, leaving Huang Xiumu behind, and he took Amu to the Guozijian and returned to the imperial study.

There is no one else in the imperial study except for Chang Gonggong.

Li Chenan looked at Chang's father-in-law and asked, "Has my second uncle done the matter?" ”

"Back to the Regent, it's all right!"

Li Chenan breathed a sigh of relief and laughed, "Okay! ”

"This can be regarded as solving the most urgent crisis at hand, you go and tell the ministries that when Ming'er is young, a court meeting will be held in Hanyuan Palace...... Civil and military officials above the fourth grade participated. ”

"The old slave commands."

"By the way, Lord Regent, a letter was sent to you from outside the palace just now."

"Who sent it?"

"The garden is full of flowers, and the old man is Confucian."

"Oh."

Li Chenan took the letter, and Chang Gonggong bowed and retreated.

Li Chenan sat in front of the tea table and opened the letter with a happy face.

I've been so busy for more than a month that I really forgot to go to Tai Academy to see this old brother.

Pulling out the letter paper, there were only two simple sentences in it:

"Brother, I know you're busy."

"If you're done, leave the palace, my brother is waiting for you at the south gate!"

Li Chen'an raised his eyebrows, he didn't say anything in the letter, but since Hua Manting was waiting at the south gate in person, he thought it was an important matter.

He looked at the pile of folds on the dragon case, and suddenly felt a little pain in his brain.

"Hey......"

"Amu!"

Amu was stunned, "What?" ”

"Do you know what is the most important thing in this world?"

Amu suddenly opened his mouth, "...... The skills of the Grand Master? ”

Li Chenan shook his head, "No." ”

"What's that?"

"Talent!"

"The most important thing in this world is the talent that can be reused!"

Amu pursed his lips, thinking that it was you, and for me, it was the pinnacle of martial arts!

"Aren't you talented?"

Li Chenan choked and glared at Amu: "What I want is relaxation!" ”

"Then there has to be someone who makes it easy for me to use!"

"If they can hold on, I'll be able to relax, you know?"

Amu shook his head after five breaths, "I don't understand, I only know that those who can work harder, if you can, you should work hard!" ”

As if feeling that this was not enough, he added: "You are a hard worker, and a happy person of a country...... Value! ”

It's worth it!

Li Chenan felt that he couldn't communicate with this wood.

He stood up and waved his hand, "Go!" ”

“…… It's not time for the next dynasty yet, and the junior brother's dog meat is probably not stewed yet, and the officials are afraid that they will follow suit when they see that you ran away in advance, so it's not good to leave at this moment! ”

Li Chen'an glanced at Amu, raised his steps and walked out of the door, "I'm the regent!" ”

"Who dares to care about me?!"

"Let's go, Brother Hua is waiting for me outside, what should I do if such a big wind and snow freezes Brother Hua?"

Amu looked at Li Chen'an's back, and the corners of his mouth suddenly turned up to reveal a smile.

He walked up and followed.

I think this is what Li Chenan is supposed to be.
