Datang: Acting as a celestial mystery at the beginning

Li Yi'an saw all of this factory. It is not small and there are many workers. First, he asked, "Where does the money you make come from?"

"Fang Yucheng gave it."

Li Chengqian said with a smile: "Fang Yucheng and I just mentioned this matter, and he immediately gave me money to toss about it."

Your Royal Highness, the future emperor, if you ask Fang Yucheng for money, how dare he not give it?Even if there is no threat, Fang Yucheng is willing to spend any money just for the reason of closer relationship with the royal family.

Li Yi'an has not been in Chang'an for a long time, Li Shimin's management of Li Chengqian should be a little more relaxed, and he will start to let himself go, daring to do anything.

"And what are you going to show us?"

Li Yian asked again.

"it's here!"

They came to an open space behind the factory.

There is a hollow iron rod here, about the size of a fist, not very long, fixed on a special iron frame, one end is open, and the other end has a movable valve, which can be closed tightly.

"What is this?"

Li Yi'an looked around, and felt a little familiar, from the appearance, it looked like a simple earthen cannon.

"Sir, he told us about the usefulness of gunpowder before. I made all the firearms, so I started to try to make artillery. This is the first one we made."

Li Chengqian said excitedly: "I sent a batch of those firearms to Cheng Fatty and the others. They were full of praise. They have already asked Aye to ask the Ministry of War to buy weapons from us. As long as they are promoted, the national strength of Datang can be greatly enhanced." .It’s the first time I’ve made a cannon, I haven’t tried it, I’ll try it when you come back, sir.”

Li Yi'an had to admit that His Royal Highness is very good at playing and has a lot of ideas, but it is a pity that he was born in the wrong age. If it is a future generation, he should have achieved something in science.

"Try it."

Li Yi'an looked left and right, and pulled Li Lizhi's hand back, fearing that there would be danger.

"Come and try!"

Hearing Li Chengqian's order, Tang Songling hurriedly asked people to put gunpowder in it, as well as a simple iron bullet.

After all preparations were completed, they backed away in an instant.

Several guards took torches and waited for the order to light the fuse.

"Lizhi, cover your ears first."

Li Yi'an said: "Light it up!"

Li Lizhi couldn't understand what it was, her big eyes were shining, she looked out curiously, but obediently covered her ears.

boom!

A burst of noise appeared in front of their eyes, and the ground felt like it was shaking.

Then I saw that the iron bomb was pushed out by the thrust of the explosion, only flew about a foot, and fell weakly.

"Failed!"

Li Chengqian said disappointedly.

After studying for so long, and finally ended in failure, I was naturally a little uncomfortable.

Li Yi'an looked at their expressions, thought for a moment and asked, "Are you really going to get these things?"

Li Chengqian said with certainty: "That's right, I think firearms are definitely the strongest weapons, and they are beneficial and harmless to Datang. Sir, can you help me?"

This favor, Li Yi'an thought he could help.

In the era of cold weapons, hot weapons are just a plug-in. If they are used on the battlefield, the enemy can only be killed by their firearms.

If Datang's army has hot weapons, it can create a more powerful empire.

This is also a transformation of later history!

Li Yi'an pondered for a while: "It's okay to ask me to help, but this must be unconditionally handed over to the Ministry of War and the Ministry of Industry. As the crown prince, if you continue to mess around and ruin the affairs of the East Palace, what do you think the King of Yue will do if he finds out? "

Upon hearing the word "King of Yue", Li Chengqian froze instantly, feeling an unprecedented threat.

This is indeed a problem for him.

"I agreed."

Li Chengqian said.

"If you want to claim credit, tell His Majesty immediately when you go back, there is no need to hide it."

Li Yi'an continued: "If you make it public in advance, other people who want to attack you will not find a point."

"I'll do it later."

Li Chengqian finally realized that he was wrong.

Seeing that he had agreed, Li Yian asked them for some paper and pens, first drew some sketches, and then asked someone to call Ah Shui over.

Who is Ah Shui, Li Chengqian and the others already know each other.

When he first arrived, he picked up the sketch and looked at it for a long time, thinking about whether it could be realized.

"How does brother-in-law feel?"

Li Yian asked.

"I think you can give it a try, but all the people here have to listen to my arrangements."

Ah Shui said.

Li Chengqian nodded first and said: "Of course there is no problem. If anyone dares to be disobedient, you can just tell Mr. I have plenty of ways to punish them."

Li Yi'an said: "Brother-in-law, I will trouble you next time. Before handing it over to the Ministry of War, brother-in-law will be in charge temporarily. After handing it over to the Ministry of War, I will make it clear to Duke Du that brother-in-law is in charge of the main technology here."

"No problem at all!"

Li Chengqian had no opinion at all.

As long as a gentleman participates, he can imagine that his conjecture is about to come true.

After reading this briefly, Li Yi'an also lost interest, thinking whether to go to Sun Simiao for a chat about what happened back then.

It's just that he just came up with this idea when someone rushed in, a guard from the Eastern Palace, and hurriedly said: "Your Highness, princess, it's not good, the queen suddenly fell ill."

"what?"

Brother and sister Li Chengqian yelled, and said quickly: "Go back to the palace, hurry back to the palace, sir, do you want to come too?"

"Okay, then find someone to inform Sun Zhenren!"

Li Yi'an led them in the carriage and galloped towards the palace at high speed.

When they returned to the bedroom, Li Shimin and Li Tai were already standing there anxiously, and the few imperial doctors were helpless, not knowing what to do.

"Sir, it's just in time for you to come, come and see the queen for me!"

Li Shimin said eagerly.

They knew about Li Yi'an's medical skills in the case of smallpox back then, and even Sun Simiao felt inferior to him.

"Sir, please save my mother!"

Li Lizhi took Li Yi'an's hand and begged with tears.

"I'll take a look first, don't worry!"

Li Yi'an went over to feel the pulse for a while.

The eldest grandson Wugou was suffering from an old disease, Li Yi'an knew about it, and according to future generations' speculation, it was still asthma.

After a simple inspection, he was sure that it was indeed asthma. Not long ago, his eldest grandson Wugou gave birth to Princess Chengyang, and his body was weak. Asthma attacks at this time, it can be as serious as it needs to be.

"Give me the silver needle!"

Li Yi'an said.

Immediately an imperial physician came over with a silver needle.

He simply administered needles to stabilize her condition, and it happened that Sun Simiao came to diagnose her pulse first.

After a long time, Li Yi'an asked, "Sun Zhenren, what do you think?"

"The queen's condition has been stabilized by the husband. I only have one prescription to recuperate my body. That's all. What about you, sir?"

Sun Simiao asked.

"The queen's illness is quite serious. I can treat it, but it cannot be cured. There is a possibility of recurrence in the future."

Li Yi'an expressed his thoughts.

Whether the eldest grandson Wugou will die of illness in the future, Li Yi'an can't guarantee.

Sun Simiao turned back and said: "Your Majesty, I think you can follow the method of the master. The medical skills of the master are still superior to mine."

"Sir, I'm sorry to trouble you!"

Li Shimin said nervously.

"You can change your life against the sky once, do you want to use it?"

Just when Li Yi'an was about to write down the prescription, the system rarely showed up a reminder automatically.
