In fact, although it was not a hydraulic lathe that was first made, nor was it the legendary Emperor of the Apocalypse.

Not to mention, the cylindrical shells that involved a number of new technologies.

These things have to wait until they are made before they can be seen in power.

But apparently it wasn't so fast, and even the building of their new arsenal, built by the river, had not yet begun to be built.

The first thing he came up with was the evolution of black powder, maroon gunpowder.

At this time, Sun Yuanhua was accompanying a big official, and judging from his respect for that big official, you can see who this big official's identity is.

This is one of the current cabinet scholars, and Sun Yuanhua's teacher Xu Guangqi.

Xu Guangqi is very different from other Donglin Party ministers.

He doesn't discriminate against new manufacturing techniques and new weapons developments, and he doesn't think these things are a matter of strange skills.

Xu Guangqi felt that improving the development of firearms and artillery would definitely be of great benefit to the Ming Dynasty's war strength.

Now that the Ming Dynasty is surrounded by enemies, if they don't quickly increase the power of firearms and artillery, then they will always be at a disadvantage to this Jiannu cavalry.

But the problem is that Xu Guangqi actually did not have any expectations for this new maroon gunpowder.

"Your Majesty, this is a bit of a fool, the proportion of gunpowder such a thing, it has to go through thousands of tests before its power can be increased to the maximum."

"Judging from the current situation, the proportion of gunpowder in the Ming army has almost been tested to the extreme."

"Your Majesty has never made gunpowder, and he suddenly gave you this recipe to get it."

"If it's really any use, then hell"

Obviously, Xu Guangqi thought that no matter how much Zhu Youxiao tried, there was no way to raise the power of this black powder to another level.

When Sun Yuanhua heard this, he also felt very helpless.

"Your Majesty, he said that this is the recipe given to him by Emperor Taizu, saying that it can increase the power of this gunpowder by one-half."

When Xu Guangqi heard this, he became even more angry.

"Nonsense, this doesn't matter whether it is true or false that His Majesty has seen Emperor Taizu after he ascended to heaven."

"But even if this thing is true, then Emperor Taizu has never fired a cannon!"

When Sun Yuanhua heard this, his eyes quickly turned around, looking a little nervous.

Then he pointed to his entourage and Xu Guangqi's attendants around him.

"You stand forty steps away, and I have something important to discuss with Scholar Xu."

As soon as Sun Yuanhua's entourage heard this order, they immediately dispersed.

And Xu Guangqi's entourage, after hearing this, all looked at Xu Guangqi.

"Disperse first!"

After the entourage got Xu Guangqi's permission, they finally dispersed.

"Teacher, you still have to say less in the future."

"The disciple heard this, but it is not a big deal, if other traitors are allowed to listen to it, it is inevitable that there will be a suspicion of slandering the monarch's father."

"If you are used by traitors, it will be enough for you to eat a pot."

When Xu Guangqi heard this, he was furious on the spot.

"The old man does things above board, that's when this word gets out, so what?"

"It's a big deal, the old man resigned again and went into hiding."

"Besides, don't look at Your Majesty, although he is a faint king, in fact, his mind is not so narrow as this."

Sun Yuanhua shook his head, he didn't agree with Xu Guangqi's words.

"Teacher, Your Majesty knows about this matter, although it is not like this, I am afraid that after Wei Zhongxian knows about it, it will be difficult to use it."

Sun Yuanhua was right.

This Xu Guangqi actually belongs to the Donglin Party in a strict sense, and does not belong to the same camp as Wei Zhongxian.

If Wei Zhongxian knew that he was like this, it would be reasonable to kill him.

Xu Guangqi looked at this Sun Yuanhua and sighed, although this disciple is very talented in terms of the technology of these firearms and artillery.

But Sun Yuanhua's sense of touch in the officialdom of the court is too low.

"Haven't you seen the things in the court clearly?"

His Majesty was already curtailing Wei Zhongxian's rights, and even the Nake clan was executed by His Majesty. ”

"This eunuch won't last many days!"

Sun Yuanhua still didn't agree with Xu Guangqi's words in his heart.

He has had more opportunities to contact Zhu Youxiao recently, even more than Xu Guangqi.

He obviously felt that Zhu Youxiao just wanted to restrict Wei Zhongxian's rights, but he didn't want to kill Wei Zhongxian at all.

For example, the entry of Sun Chengzong and Xu Guangqi into the cabinet is the goal that His Majesty achieved with the help of Wei Zhongxian.

If Wei Zhongxian is killed, then His Majesty will lose the best sword, how could he do such a thing.

Xu Guangqi saw Sun Yuanhua's thoughtful expression, and thought that it was his own words that hurt him.

He secretly regretted it in his heart.

This disciple was gifted with firearms technology and had great respect for him.

His words were still a little too cold.

"Alright, let's not talk about that."

"Let's take a look at the gunpowder formula given to you by His Majesty first, what is going on!"

"The old man doesn't believe that Emperor Taizu can make gunpowder."

"Later, his gunpowder can't be lit and can't be shot, and then the old man will help him clean up the aftermath."

What Zhu Youxiao handed over to them was the recipe for maroon gunpowder.

This gunpowder was even used until the end of the Qing Dynasty, the Beiyang period.

His manufacturing process is actually not complicated, and even a little simple.

Because the maroon gunpowder is simply improved from black gunpowder.

Its composition is the same as that of black powder, except that the ratio of nitrate, sulfur and carbon in black powder is changed from 75:10:15 to 80:4:16.

For Zhu Youxiao, who understands chemistry, only the amount of oxidant nitrate has been increased, and the amount of explosive sulfur has been reduced.

The charcoal used in the gunpowder is also different from ordinary black powder, that is, only willow wood is used.

The willow wood is made by insufficient carbonization in an iron bucket at about 90-120 degrees Celsius.

The medicine cake is hexagonal single hole, hexagonal seven hole and other shapes.

Xu Guangqi and Sun Yuanhua came to the front of a Hongyi cannon, which was pulled out of the Beijing camp and belonged to their arsenal in the future.

In fact, if it were normal times, this kind of big killing weapon would generally be unwilling to hand it over to Zhu Chunchen, the Duke of Chengguo.

But some time ago, Zhu Chunchen had just offended Zhu Youxiao.

Now that Zhu Youxiao has given him an order, he doesn't dare not hand it in at all.

In other words, even if Zhu Chunchen didn't offend Zhu Youxiao, but Zhu Youxiao asked him for a Hongyi cannon, he didn't dare not give it.

The current Zhu Youxiao has a eunuch party in hand, and whoever kills whom.

Xu Guangqi and Sun Yuanhua saw the gunner with their own eyes and stuffed the newly made maroon gunpowder into the Hongyi cannon.

Then, after the gunner had built up, he stuffed in another iron cannonball.
