Because the current great man is more difficult to purify, the difference from the black gunpowder in later generations is that the ratio of each batch of black gunpowder products will also be different due to the different materials.

"As far as I know, the gunpowder produced by the cavalry comes from the Long Road, and the sulfur comes from Hanzhong..." Wang Chang said slowly, "As the master of the world's craftsmen, how could Mao Shaofu not even understand such a superficial truth? Could it be that it is to frame the cavalry, so he doesn't care much about it... Your Majesty, now the truth is revealed, and the truth is revealed, and I would like to punish Mao Shaofu for framed accusation!"

Either you are incompetent or falsely accused. Anyway, Mao Zong will choose one!

"You, you..." Mao Zong was angry for a moment and couldn't speak.

Is there a formula that is useful?

Take saltpeter as an example. Nowadays, the raw materials of saltpeter in Guanzhong gunpowder are produced in Longdao, Hedong, and Sichuan, which are different, and the contents of impurities are different. If they are not deposited and allocated, but mixed in a fixed proportion, it will inevitably lead to some smoke, some are strong in fire, and some are farts with a puff...

As for those so-called ratios, and then the next day, their subordinates could say that they had already matched gunpowder and could kill all directions, which was basically impossible.

Wang Chang followed the cavalry, and after a long time, he naturally knew some of the cavalry's methods.

The methods of the cavalry have always been open-minded.

It's like this gunpowder ratio.

Gunpowder is real, and the ratio is also real. If you want to get tribute for free, you can do it. After all, the cavalry is still a minister of the Han Dynasty, but as a tribute, it is naturally just a little bit every year. How many times can it be used?

I want to prepare it myself according to the recipe, and the raw materials are in Feiqian territory...

In addition, in Shandong, there is no large-scale craftsman craftsmanship like a cavalry, so that most Shandong craftsmen obey orders and do whatever they want to do. They have no sense of innovation. Even if some people innovate, they will hide carefully. After all, there is no copyright law in Shandong, and the things developed by craftsmen will basically become the property of others almost for free.

In this case, craftsmen in Shandong are increasingly reluctant to study new things. Not only does it take time and energy, it has no benefits, and may even attract so-called insults. After all, craftsmen need to spend time and energy to study, which may affect their daily work.

"The King of Envoy is a little restless..." Cheng Yu stood up and went out, "Since the King of Envoy said that the proportion of the cavalry gunpowder was used in the Hanzhong of Longdao, why did we purchase the same saltpeter sulfur in Longdao and the proportion was still not comparable to the tribute... But I wonder what the King of Envoy explained?"
