Guests follow the host's will.

On Ling Zhen's territory, Yu Yin naturally couldn't refute Ling Zhen's idea.

He called Gao Chong and accompanied Ling Zhen back to the hall.

At this time, Ling Wei ordered people to serve wine. Ling Zhen raised his glass and invited him to drink it all. He wiped the wine stains on his beard on his mouth, breathed a sigh of relief, and then he talked endlessly, explaining to Yu Yin the specific process of his cannon building.

Speaking of which, this process was boring, but Zhang Lingzhen was very excited.

Gao Chong and Ling Wei were sleepy when they heard this, but Yu Yin did not care at all.

Speaking of gunpowder, we have to mention an alchemy called "Fire Practice Alchemy". In fact, the origin of gunpowder also comes from ancient alchemy. As early as the Jin Dynasty, Ge Hong had records of fire practice alchemy in "Baopuzi".

In the middle of the Tang Dynasty, there was a method called Qingxuzi, which proposed a formula of "two liang of sulfur, two liang of nitrogen, three and a half qian of Aristolochia, powdered with the right and mix well", which officially made the formula of gunpowder tend to be in the prototype. However, whether it was Ge Hong or Qingxuzi, or even gunpowder craftsmen in the Northern Song Dynasty, they all made changes based on sulfur and nitrate.

Among the three elements of gunpowder, although the most important "charcoal" element was discovered by people, it was not taken seriously.

Ling Zhen also believes that the function of 'charcoal' is actually to help burn.

Therefore, in the formula he tested the gun, the ratio of sulfur to nitrate was about 1:2, which basically reached the ratio of gunpowder in later generations. However, the ratio of "carbon" has never been increased, and the ratio to sulfur has remained at a ratio of 1:2 or 1.5:2. The ratio of "carbon" is far from reaching the ratio of 1:2:3 required by black gunpowder in later generations.

Although Yu Yin is not very clear about chemistry, he still knows the proportion of this black gunpowder.

He naturally knew the ratio of 1:2:3, so he vaguely found the main reason why Ling Zhen failed to test the artillery...
