Wang Gong factory exploded.

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

Wang Gongchang was the place where the Ming Dynasty researched gunpowder and hoarded gunpowder, and during the Apocalypse, this powder magazine exploded.

Xia Yuan had also watched documentaries in his previous life, which exaggerated this incident quite terrifyingly, and some experts even speculated that the power of this explosion was comparable to that of an atomic bomb.

It is difficult to say whether there is the power of the atomic bomb explosion, but the terrible is really terrible, the stone lion weighing 5,000 catties, the old tree hugged by several people flying in the sky, not to mention the people nearby, countless deaths and injuries within a radius of several kilometers, tragic people.

The Emperor of the Apocalypse who was far away in the Forbidden City was blown under the table, the Qianqing Palace was blown up, and the crown prince, who was less than a year old, was also frightened to death by the explosion.

indirectly led to the carpenter emperor having no queen, which led to the later emperor Chongzhen ascending the throne, and then hanging himself on the old crooked neck tree.

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

Far away, in short, the place of Wang Gongchang did explode once during the apocalypse, although the cause of the explosion is different, but it is likely to be related to the underground natural gas leakage.

According to historical records, there were small earthquakes in the Gyeonggi area a few days before the explosion, and even seismic waves continued, so it is likely that the natural gas leak caused by the earthquake, and unfortunately, there was a large amount of natural gas underneath the Wanggong plant.

The explosion of natural gas was originally an exothermic reaction, and the Wang Gong factory itself was a heavy place for hoarding gunpowder, and there were countless gunpowder stored in it, not to mention that the characteristic of black powder was that a little spark could be detonated, so boom!

With thoughts surging in his mind, Xia Yuan silently kept this matter in mind, planning to find an opportunity in the future to see if he could let the imperial court move Wang Gongchang.

He hasn't come up with a suitable excuse yet, he can't say that Wang Gongchang's feng shui is not good, hurry up and move, otherwise it will be blown up 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 blow it up."

Reluctantly prevaricating, Xia Yuan immediately changed the topic and asked, "If you go to Wang Gong's factory to get some nitrate, can you take it out?" ”

As Gu Dayong said before, it is difficult to buy fire nitrate in the market.

How difficult it is almost as difficult as it is to buy a Gatling in a supermarket in later generations.

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

In particular, sulfur and saltpeter, the two main raw materials for making gunpowder, are extremely strictly controlled, and the people are not allowed to sell them privately.

And if you dare to store this kind of thing privately at home, you will also be punished.

So Xia Yuan can only pin his hopes on Wang Gong's factory.

"This is easy, Gu Companion, you go to Wang Gong's factory and take it to the palace."

Zhu Houzhao agreed quite simply, if he got the prepared gunpowder from Wang Gongchang, it would be very troublesome, those things were registered, but if he made a little bit, he would have to be reported, and if he didn't do it, it would reach the ears of his father.

But making ignition nitration is completely trivial, after all, it's just some raw materials.

As he spoke, he took out a pile of chicken and dog fragments, treasure money, silver, cricket jars, dice, jade pendants, fire folds, iron rings, and daggers. There's everything.

Xia Yuan's eyes were straight, good guy, this is a robot cat, right?

And in the midst of all this mess, there is also a boxy seal.

Zhu Houzhao picked up the seal and handed it to Gu Companion, "You take the crown prince treasure of the palace, go to Wang Gongchang to get a little fire and nitrate, and it will cost about a hundred catties."

"Huh."

Before he could finish speaking, Xia Yuan hurriedly interrupted, "You don't need a hundred catties, you don't need that much, it's enough to take one catty or two catties." ”

What he said was to take a little fire and take it out, but what Zhu Houzhao said was to get a little, he thought that this thing was the same as himself, and the result was 100 million points.

"That's okay, just follow what the master said, take three catties out."

Gu Dayong replied, took the seal and left, while Xia Yuan began to prepare for the large artillery battle.

As he said earlier, this thing is not technical at all.

If you want to make a more powerful cannonball, you need nothing more than a larger container, and then stuff the corresponding gunpowder into it, of course, in the right proportions.

And the container is also related to the power of the final cannon, the best container is the tin can, but this kind of thing is not something you can find.

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

For example, bamboo.

In the small garden in the backyard, there is a small bamboo forest, where many old bamboos grow, and they are even as thick as the mouth of a bowl.

Xia Yuan turned around and went into the backyard to choose the right bamboo, and the matter of pouring gunpowder was handed over to Zhu Houzhao, to be exact, it fell on his guards.

When Xia Yuan came out with a calf-thick bamboo, his cheeks couldn't help but twitch a few times, the black gunpowder had been prepared a lot, and several empty fireworks boxes were thrown next to him, and Zhu Houzhao also commanded the guards to continue pouring gunpowder out with the fireworks boxes.

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

"Enough is enough, don't fall, enough is enough."

"Is it enough?"

"Enough, enough."

As he spoke, Xia Yuan put the bamboo on the ground, and took out a small scale from his arms, this kind of scale is very common in the Ming Dynasty, and it is also a must-have thing for many families.

"Here, weigh it with this scale and see how many catties of gunpowder there are."

Zhu Houzhao took the small scale, handed it to a guard next to him, and asked him to weigh it, and then asked, "What are you doing with this?" ”

"Weigh, then calculate the proportions."

"Oh"

Zhu Houzhao seemed to understand or not.

"Your Highness, the inferior people have weighed it, and the total amount of these gunpowder is ten catties and four taels."

"Ten pounds and four taels."

Xia Yuan picked up the small stick he had used just now and began to calculate on the snow, the proportion of charcoal is thirty percent, that is, a little more than three catties of charcoal, and the proportion of sulfur is two percent, that is, about two catties.

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

According to the existing proportion of charcoal and sulfur, that is to say, fifteen catties of potassium nitrate are needed.

Well, it's not enough, even if you add the gunpowder that Gu Dayong hasn't taken yet, it's only eight catties.

However, Xia Yuan didn't want to do such a big artillery battle, and removed half of the gunpowder, which was just enough for the correct proportion.

He was about to talk about it, but Zhu Houzhao finally couldn't help but ask, "Master, what are these things you painted on the ground?" ”

"Numbers and formulas."

Xia Yuan threw the wooden stick in his hand to the side, "Haven't you seen Wang Shouren use it?" ”

"Nope."

"He will, if you want to learn, let him teach you later."

Hearing this, Zhu Houzhao immediately asked the question he was most concerned about, "This number and formula are also related to practicing divine skills?" ”

"It doesn't matter."

"Oh, then I won't study."
