Wang Gong Factory was founded in the Hongwu period of the early Ming Dynasty. It was just a cast iron factory at the beginning. It was expanded into an arsenal after Yongle moved its capital, which specialized in manufacturing weapons, equipment, muskets, artillery and ammunition for the imperial guards and the Beijing camp.

This Wang Gong Factory is very famous in history. However, this famous does not mean that the weapons, equipment, or muskets and cannons made here are famous. The reason why Wang Gong Factory is famous is because of a big explosion, an unprecedented and bizarre explosion, which is known in history as the Wang Gong Factory Big Bang or the Apocalypse Big Bang.

According to historical records such as "Ming Shilu", "Ming History", "Guo Quo", "Ming Ji Beilu", and "Zhuo Zhongzhi", the explosion destroyed tens of thousands of houses within a radius of more than ten miles from Shunchengmen Street in the east to Jingbu Street in the north, causing at least 20,000 casualties.

In addition, there are bizarre records in these historical materials that there are some big pits that are about 40 or 50 steps wide and 2 meters deep in flat ground, stone lions weighing thousands of pounds were blown away more than ten miles, and more than ten big trees were blown into Miyun territory dozens of miles away.

This also made the Wang Gongchang Big Bang, the Tungus Bang, and the Indian Death Hill incident a three unsolved mystery in history.

Why do you say so?

Isn’t it normal for gunpowder explosion to cause damage to houses and casualties? Why are these three unsolved mysteries in history?

In fact, the reason is the power of this explosion. According to a comprehensive analysis of various historical records, only 10,000 to 20,000 tons of yellow SE explosives can produce such great power. At that time, Wanggong Factory stored a total of more than 2 million kilograms of black gunpowder, that is, more than 1,000 tons of ordinary black gunpowder.

Yellow Se explosives are special explosives developed in later generations. The explosion power is at least five times that of black gunpowder. However, Wang Gongchang's black gunpowder explosion this time is more than ten times that of yellow se explosives, which is quite bizarre.

Some people say that this is definitely a meteorite from the sky, some people say that this should be an explosion caused by an earthquake, and some people even speculate that this is a big explosion caused by the crash of an alien spacecraft. Otherwise, it would be impossible to have such great power. You must know that during the Ming Dynasty, there was no yellow SE explosive, only black gunpowder.

Of course, the Apocalypse explosion has not yet happened, and Wang Gong Factory is still there, and Taichang is also planning to transform it into a factory specializing in the manufacture of muskets and artillery.

As for the gunpowder stored here, including the workshops for making gunpowder, he asked to move all to Wulitun between Guangqumen and Zuoanmen. It was the southeast corner of the outer city. Except for more than a thousand Jingying Tunwei, there was no one living within a radius of more than ten miles, and even if an explosion occurred, few people would be injured.

After several days of handling and repair, Wang Gong Factory finally renovated and new artillery began to be cast. Taichang naturally couldn't wait to come over.

This place was originally jointly managed by the Ministry of Works and the Inner Palace Supervisor, and there were also Jingying Tun Guards patrolling and guarding around. There was definitely no problem with safety. After the gunpowder was moved away, there would be no explosion here. Therefore, he did not bring too many people, and only Qianjin Yiwei was accompanying him to protect him.

The scope of Wanggong Factory is not ordinary. On the right half of Guohong Temple Street, except for the Yongen Temple, all belong to Wanggong Factory. In a large circle of walls, there are more than 30 cast iron workshops, sand casting workshops, iron scheduling workshops, grinding workshops, etc., and there are more than 30 craftsmen and foremen.

At this moment, Bi Maokang, Wang Zheng and Sun Yuanhua have also moved here. They are organizing people to cast new artillery. The entire factory is crowded and bustling.

It's really not that big here. Taichang took Ge Cheng, Cao Huachun, Liu Shiyou and others with a leading eunuch for about a quarter of an hour before he arrived at the sand casting workshop where Sun Yuanhua and others were busy.

This is a large convertible hood, surrounded by bricks like a threshold, and there are pieces of sand fields like dry land.

Bi Maokang, Wang Zheng and Sun Yuanhua were standing among several pieces of sand fields, and were excitedly directing more than ten craftsmen to dig things in the sand.

The components of the first batch of ten light guns have been turned and cast, so they are waiting to be pulled out and processed. They are naturally so excited that they are too excited.

This is also the reason why Taichang couldn't wait to come over.

Question, why is this sand casting workshop so simple? Taichang couldn't help but walk to Sun Yuanhua and asked, "Chuyang, no walls are built here. If it is windy and rainy, will the rain water float in?"

Sun Yuanhua hurriedly bowed and replied excitedly: "Master, this sand turning is a fine job. If the light is not good, it will easily break the sand mold. Therefore, the walls are usually not built in places where sand turning is turned."

Oh, so that's the case, Taichang couldn't help but nodded slightly.

This kind of chatting between the monarch and his subjects is very common in Ciqing Palace, because Taichang has said that there is no need to give a big gift when he is busy with work. Bi Maokang, Wang Zheng, Sun Yuanhua and others have long been accustomed to this.

The craftsmen here were frightened by Sun Yuanhua's "Emperor".

This is the Emperor!

Why doesn’t the emperor wear a dragon robe?

Why no one sang "The Emperor is here"?

The busy craftsmen in Shatian were all trembling with fear, and hurriedly lay down and kowtowed hard, "Your Majesty, I don't know if it's the emperor's arrival, and I deserve to die!"

Uh, this one.

Taichang thought for a while, then said loudly: "Okay, get up. You can avoid politeness when you see me when you work in the future. Think about it. If you see me like this when you pour molten iron, you will not be scalded to death if you pour the crucible filled with molten iron!"

When the craftsmen heard this, they were all stunned.

This seems to make sense.

Problem, even if you are scalded to death, you can't be rude to the emperor!

Seeing this, Sun Yuanhua couldn't help but raise his hand and said, "Okay, okay, this is the emperor's oral order. What are you thinking about? Get up and continue to turn it over!"

After hearing this, a group of craftsmen carefully got up, picked up the wooden hoe and wooden rake beside them, bent down and continued to flip in the sand field.

At this time, Taichang picked up a shell on the flatbed cart next to him and looked carefully.

The iron lumps that were turned into sand were not as beautiful as the carefully carved wooden model. The surface of the entire shell seemed to be covered with ant nest, full of fine holes and sand. I don’t know how difficult it is to process it.

He picked up a few small parts and looked through them carefully for a while. Sun Yuanhua couldn't wait to say, "Okay, I've got enough five sets. You guys continue to flip here. Old Li, hurry up and push the car to clean it up."

When an old craftsman heard this, he quickly called two young men next to him to push the cart and walk out.

Sun Yuanhua couldn't wait to ask, "Your Majesty, are you going to have a look?"

Of course, I just saw how you process artillery?

Taichang nodded without hesitation and said, "Let's go, I'll go and have a look with you."

Upon hearing this, Sun Yuanhua hurriedly followed everyone.

The cleaning place was not far from the place where sand casting was turned, and everyone followed the flatbed cart for more than a hundred steps before they arrived.

This is also a large convertible, with sinks half a person high inside. Lao Li pushed the things in and shouted, and the people inside surrounded the flatbed cart. One person picked up a part and carefully knocked it on the ground for a while. Then he picked up an iron brush and soaked the parts in the sink and skillfully cleaned them.

This work seemed simple, but Old Li carefully inspected each cleaned part very carefully.

After a while, he threw several parts on the ground.

Obviously, these are all uncast waste products.

Sun Yuanhua couldn't help but twitched a few times, but he didn't say anything, because this simplest sand casting is the easiest to produce defective products, so it's normal to throw a few of them.

After this cleaning, more than a dozen defective products were produced. Sun Yuanhua didn't say anything. He waved his hand and ordered the old head to push a cart of parts to the reaming workshop.

There are walls in this workshop, but there are only three walls, which are not opposite the passage. There are various reaming machines inside, including horizontal and vertical ones, with about a dozen large and small feet.

Taichang didn't say anything, just watched from the side, Sun Yuanhua, Bi Maokang and Wang Zheng were in charge, asking the craftsmen inside to fix various parts on different beds and prepare to open the hinge.

These craftsmen are roughly used to the approachability of these three adults. As long as no one calls them the emperor, they are all very normal, each of them is busy with their work, without any restrained expressions.

The reaming method does not seem to be complicated. It is roughly to stab the prepared reamer into the hole of the part, then turn the reamer, and then stumble it. First, use a small dot thick reamer, then change to a large dot fine reamer, and then change to a fine reamer that meets the required size.

Small holes in parts such as gun doors and gun ears seem to be simple to be reliably relied, and they can be done in a few clicks. However, problems arise when the barrel and sub-shells are relied at the beginning.
