"Sir, the young ones have been able to reduce the weight of Chentian Thunder by half and the power is not damaged at all. If they use a machine or a trench, their throwing distance can be doubled." Ou Zhige said proudly.

"It's not just how European craftsmen can improve the ratio of gunpowder?" Zhu Ping'an asked again, this is the most critical issue for firearms.

"Caomin studied the gunpowder formula recorded in books such as "Fire Dragon Artifact Formation", "Gurt Powder Record", etc. There are more than 90 types of gunpowder formulas recorded. One by one, they found that the five of them were the most powerful. They carefully studied the five gunpowder formulas and tried many times. Finally, the gunpowder formula was determined to be nitrogen, sulfur, and charcoal ratio was 81% 10%. In order to increase the burning speed of gunpowder, I also learned from the ancients to increase the fuel to fuel. After hundreds of tests, it was determined that it was the best to increase the clean oil. In order to increase the lethality of the thunder, Caomin also added aconitum poison smoke..."

The Ou Jiangshi replied in detail.

Then, he said with gratitude and confidence, "Thank you for the great kindness of your wife, I will give the "Fire Dragon Sutra" to the grass people. I believe that if you give the grass people a little more time, the grass people can improve the sky-shaking thunder again."

After hearing Ou Zhige's words, Zhu Ping'an admired and sighed. He admired that his gunpowder ratio was approaching black gunpowder. He sighed that his research direction was still biased. It was a slight difference that he lost a thousand miles. No wonder he failed to see the truth.

The gunpowder formulas studied by the European craftsman are nitrate, sulfur, and charcoal 8:1:1. In fact, it is quite close to the ratio of black gunpowder saltpeter, sulfur, and charcoal 7.5:1:1.5. For the feudal era of the Ming Dynasty, which did not pay attention to science and did not pay attention to theoretical research, it was already excellent, but it still had some deviations from the powerful black gunpowder, especially after adding the ignition-enhancing clean oil and lethal poisonous smoke, the ratio of gunpowder became more complicated and impure, and it was far from developing black gunpowder, so its power was naturally discounted.

In fact, as long as the gunpowder ratio is adjusted to the black gunpowder ratio, the combustion is completely sufficient.

There is no need to add clean oil. Adding it will add impurities to the gunpowder, affecting the performance of the gunpowder.

As for adding poison smoke to gunpowder, the direction is even more biased. You should know that the explosive performance of gunpowder is the most essential advantage of gunpowder and the greatest lethality of gunpowder. How can poison smoke compare with explosive performance? Moreover, how powerful can ancient poison smoke have? In the open fields, the air flow is strong.

Gunpowder is gunpowder. If you want to use poison smoke to kill, you should change the direction and develop poison gas bombs.

If you just want to have everything and want to have everything, then nothing can do.

"After I passed the imperial examination in Beijing, I was appointed as the editor of the Hanlin Academy and managed the Hanlin Academy Library. The Hanlin Academy Library Library has three floors, and it contains a large number of classics, all kinds of classics, and all kinds of rare books, including a large number of books on firearms. I was quite interested in military affairs and thought that future wars would be the era of firearms, so I read a lot of military affairs and firearms during my duty in the library."

Zhu Ping'an found the most appropriate source for his insights on firearms that are ahead of this era.

As for the royal collection, it is definitely authoritative and must be ahead, and there is no doubt that they have no way to verify it at the Hanlin Academy Library.

When he heard that Zhu Ping'an had read a large number of firearm classics in the Royal Library of Hanlin Academy, Ou Zhige's entire breathing was rapid, and he looked at Zhu Ping'an as if he was looking at a peerless treasure.

He was able to sell himself to Li Shu for a book called "The Fire Dragon Sutra", which shows how fascinated he is with the research of firearms.

If the collection is rich and the value of the collection is valuable, the entire Ming Dynasty cannot compare with the royal collection. The Hanlin Academy Library is one of the best among the royal collections. The firearm classics in it are worth thousands or tens of times more than the "Fire Dragon Sutra".

It is conceivable how excited Ou Zhige is now.
