Then I won’t learn anymore

Big explosion at Wang Gong Factory.

A very famous historical event can be said to be an unsolved mystery of the Ming Dynasty.

Wang Gongchang was the place where gunpowder was studied and stored during the Ming Dynasty. During the Tianqi period, this gunpowder depot exploded.

Xia Yuan had watched a documentary in his previous life, which exaggerated this incident into a terrifying image. Some experts even speculated that the power of this explosion was comparable to that of an atomic bomb.

It’s hard to say whether it was as powerful as an atomic bomb, but it was really scary. A stone lion weighing five thousand kilograms and an old tree hugged by several people were flying in the sky, not to mention the nearby people. Countless casualties were caused within a few kilometers, and it was tragic.

Emperor Tianqi, who was far away in the Forbidden City, was blown under the table, the Qianqing Palace was collapsed, and the crown prince who was under one year old was also frightened to death by the big explosion.

Indirectly, the Carpenter Emperor had no heirs, so the later Emperor Chongzhen ascended the throne, and then hung himself on the old crooked neck tree.

Of course, the most bizarre thing about this incident is that after the explosion, many people who were affected by the disaster had no clothes on their bodies, and many people were running naked on the streets. It is said that many of them were women.

I'm going too far. In short, the Wang Gong factory did explode once during the Tianqi years. Although there are different opinions on the cause of the explosion, it is most likely related to underground natural gas leakage.

According to historical records, there have been small earthquakes in the Gyeonggi area a few days before the explosion, and even continuous shock waves, so it is likely that the natural gas leaked due to the earthquake. Unfortunately, there is a large amount of natural gas underground in the Wanggong Factory.

The explosion of natural gas is inherently an exothermic reaction, and the Wanggong Factory itself is a major place for storing gunpowder. There are countless gunpowders stored in it, not to mention the characteristic of black powder that a spark can detonate it, so boom!

With thoughts swirling in his mind, Xia Yuan silently kept this matter in mind, planning to find an opportunity in the future to see if he could ask the court to move Wang Gongchang to a new home.

He hasn't come up with a suitable excuse yet. He can't say that the feng shui in Wang Gongchang is not good and he needs to move quickly, otherwise it will explode sooner or later.

"Oh, I mean, there's so much gunpowder in that place, it's no joke if something goes wrong, you still have to take good care of it, don't explode."

After reluctantly prevarication, Xia Yuan immediately changed the subject and asked: "If I go to Wang Gong's factory to get some fire salt, can I get it out?"

As Gu Dayong said before, it is difficult to buy fire salt on the market.

How difficult it is is almost as difficult as trying to buy a handful of Gatling in supermarkets in later generations.

Since the founding of the Ming Dynasty, the manufacture and sale of gunpowder has been strictly controlled.

In particular, sulfur and saltpeter, the two main raw materials for making gunpowder, are extremely strictly controlled. Folks are not allowed to sell them privately. If there is no imperial receipt, anyone who dares to sell such things privately will be directly punished and executed.

Anyone who dares to store such things privately at home will also be punished.

So Xia Yuan could only place his hopes on Wang Gongchang.

"It's easy, Gu Banban, just go to Wang Gongchang and get it from me."

Zhu Houzhao agreed quite simply. It would be very troublesome to get the prepared gunpowder from Wang Gong's factory. Those things were registered, and if anything was found, it would be reported. If not, it would be reported to his father. in the ears.

But making fire salt is completely trivial, after all, it is just some raw materials.

As he spoke, he dug around in his arms, and finally took out a pile of chicken and dog scraps, treasure notes, silver, cricket jars, dice, jade pendants, fire knives, iron rings, daggers. There were all kinds of things.

Xia Yuan's eyes widened when he saw it. Good guy, is this Doraemon?

And among these messy things, there is a square seal.

Zhu Houzhao picked up the seal and handed it to Gu Banban, "Take my crown prince's treasure and go to Wang Gongchang to get some fire salt. It costs about a hundred catties."

"Hey."

Before he could finish his words, Xia Yuan quickly interrupted, "You don't need a hundred catties, you don't need that much. One or two catties is enough."

What he said was to get some fire salt out, while Zhu Houzhao said to get a little bit. He thought that this guy was talking about the same thing as him, but it turned out to be hundreds of millions of dots.

"Okay, just follow the master's instructions and take out three kilograms."

Gu Dayong responded, took the seal and left, while Xia Yuan began to prepare for the large firecracker.

As he said before, this thing has no technical content at all.

If you want to make a more powerful firecracker, all you need is a larger container, and then stuff the corresponding gunpowder into it. Of course, the proportions must be correct.

The container is also related to the power of the final firecracker. The best container is a tin can, but you cannot find this kind of thing by yourself.

But it doesn't matter, you can use a container instead.

Such as bamboo.

There is a small bamboo forest in the small garden in the backyard, where many old bamboos grow, some as thick as the mouth of a bowl.

Xia Yuan turned around and went into the backyard to select suitable bamboos. The matter of pouring the gunpowder was left to Zhu Houzhao. To be precise, it fell to his guards.

When Xia Yuan came out holding a calf-thick bamboo, his cheeks couldn't help but twitch. A lot of black gunpowder had been prepared, and several empty fireworks boxes were thrown next to it, and Zhu Houzhao was still directing

The guard held the fireworks box and continued to pour gunpowder out.

Good guy, with so much gunpowder, what does he want to do, make an atomic bomb?

"Enough is enough, don't pour it down, it's enough."

"enough?"

"That's enough, that's enough."

With that said, Xia Yuan put the bamboo on the ground and took out a small scale from his arms. This kind of scale was very common in the Ming Dynasty and was also a must-have item for many families. It was used to weigh broken silver accurately during transactions.

The degree is quite high.

"Here, use this scale to weigh it and see how many kilograms of gunpowder there are."

Zhu Houzhao took the nickname, handed it to a guard next to him, and asked him to weigh it, and then asked: "What are you weighing for?"

"Weigh it and calculate the proportions."

"oh"

Zhu Houzhao said like he didn't understand.

"Your Highness, I and others have weighed the gunpowder and found that the gunpowder weighs ten kilograms and four taels in total."

"Ten pounds and four taels, right?"

Xia Yuan picked up the small stick he had just used and began to check on the snow. The proportion of charcoal was 30%, which is a little more than three kilograms of charcoal, and the proportion of sulfur was 20%, which was about two kilograms.

The standard black powder ratio is fifteen to two to three.

If we use the existing ratio of charcoal and sulfur, that means fifteen pounds of potassium nitrate is needed.

Well, it's not enough. Even if Gu Dayong adds the gunpowder that he hasn't brought over yet, it's only eight kilograms.

However, Xia Yuan never thought of making such a big firecracker, so he removed half of the gunpowder, which was almost the correct proportion.

He was about to talk about this when Zhu Houzhao finally couldn't help but asked: "Master, what are these you drew on the ground?"

"Numbers and formulas."

Xia Yuan threw the wooden stick in his hand aside, "Have you ever seen Wang Shouren use it?"

"No."

"He can also do it. If you want to learn, wait until next year and let him teach you."

After hearing this, Zhu Houzhao immediately asked the question he was most concerned about, "Does this number and formula have something to do with practicing magical skills?"

"It doesn't matter."

"Oh, then I won't study."
