Chapter 477: The Birth of Artillery
What can you do with gunpowder?
Yu Qian said that it is necessary to vigorously develop the country's military industry!
As the war was over and his homeland was recovered, this "concurrently serving Minister of War" would also return to its original owner - Zhao Kuo.
However, after the Battle of Xianyang, everyone in the court knew that Yu Qian was knowledgeable about military affairs.
Therefore, everyone felt at ease to entrust the development of gunpowder to him.
Of course, Ying Yuan was not very clear about this.
Because the moment he heard the flattery of the officials, he had already left the damaged alchemy room.
Naturally, the explosion in the alchemy room was also recorded in history books by the historian Sima Qian.
He summarized the explosion with a title: [The Big Bang]
Xu Fu, who accidentally made gunpowder and was unfortunately affected by the explosion, did not wake up until several days later.
The first thing he did after waking up was to ask about the pills in the furnace.
Where are the elixirs?
The alchemy rooms are gone.
After Xu Fu heard the eunuch who was responsible for taking care of him say that the alchemy room was almost in ruins.
It can be said that I have completely lost all hope.
It happened that Yu Qian heard the news that he had woken up and came to visit him.
Xu Fu was frightened and quickly got up from the bed, dragging his injured body, and was about to bow to Yu Qian.
Seeing this, Yu Qian stepped forward to support him and said with a smile: "Master Xu, you have performed a great service."
"You are still very weak, so some of the customary rituals can be omitted."
"I came here today, firstly to visit you, and secondly to discuss the gunpowder formula."
great merit?
visit?
gunpowder?
When all this information flooded into Xu Fu's mind, he felt a little confused.
"Master Yu, please don't tease me..."
Xu Fu didn't understand why.
Yu Qian talked about the "gunpowder" incident.
Xu Fu suddenly realized and took advantage of the situation to say, "Master Yu, you are right. It was indeed His Majesty who asked me to develop the gunpowder."
He thought to himself that if he didn't do this, his life would be in danger.
But after he said this about the gunpowder issue, Ying Yuan could no longer escape responsibility.
Yu Qian couldn't help but sigh, "Your Majesty is a rare wise ruler in history. How could he be so obsessed with alchemy?"
"Master Xu, I sincerely apologize to you. That day in the court, I was indiscriminate and harsh in attacking you."
Xu Fu was flattered and shook his head quickly, saying, "Master Yu, you are very kind."
After a pause, Yu Qian got down to business. "Regarding the matter of gunpowder, please tell us everything you know, Master Xu."
Xu Fu nodded.
The 'giant firework' he developed was actually an accident.
Fortunately, he was quite proficient in alchemy and knew what was needed for it.
After a certain proportion, the huge fireworks can be replicated.
After listening, Yu Qian asked again: "I wonder if the properties of this gunpowder can be made more stable?"
Stablize?
Xu Fu fell into deep thought.
He understood what Yu Qian meant.
If it is prepared according to the proportions used in the alchemy room, it is easy to go wrong.
Xu Fu thought for a long time and finally got some clues.
"I wonder if it's possible to wrap this gunpowder in a kind of iron sheet, which is brittle but stable."
"If you want the gunpowder to explode, just add a fuse. I just have an idea."
"I think it would be better to ask Craftsman Qin Mo to do this."
Yu Qian nodded slightly and said, "Your opinion is very pertinent. I have also thought of it."
"But there's still a problem. Even if we use a fuse, how do we get the gunpowder into the enemy camp?"
"Are you going to use a trebuchet? But if you use a fuse, I'm afraid it won't be launched in time and will injure one of our own people."
Xu Fu said, "There is indeed such a risk. What if there is something that can launch the gunpowder?"
"For example, a bow and a crossbow can shoot arrows, but it requires manpower."
"But gunpowder itself has a thrust effect..."
“…”
The two of them talked back and forth.
That night, thousands of people from the Qin State's military equipment department worked without a moment's rest.
at the same time.
The repeating crossbow invented by Zhuge Liang has also been put into large-scale production and use.
This day.
Yu Qian discussed with everyone,
"Gunpowder is still under development, and there are many uncertainties. It needs to go through multiple tests."
"But the crossbow developed by Kong Ming is very effective and has no hidden dangers."
"The repeating crossbow is naturally effective against cavalry. Perhaps this crossbow can be used by Your Majesty during his expedition to the grasslands."
"As for the gunpowder, once it is successfully developed, I will send someone to deliver it to Prime Minister Cao as soon as possible."
After hearing what he said, all the officials agreed.
Qin Hui, sitting on the chair, seemed to be thinking about something.
Finally, after a fierce ideological struggle, he decided to tell Wanyan Aguda about Zhuge Liannu.
Let him make the shield quickly.
Qin Hui did this because he had Aguda's leverage over him.
The second is to gain benefits from Aguda.
A shield can only defend, not attack.
I don't think it will pose any threat to Emperor Qin.
Therefore, Qin Hui thought about it and dared to do so.
However, he had just sent the secret letter to Aguda out of Xianyang.
hind foot.
In the Xuanzheng Hall.
Ying Yuan heard about Yu Qian's plan.
He suddenly remembered a joke: 'Fire at me'.
