"Can you find out what's mixed in it?" Gu Qingyi asked.

Wu Yu frowned slightly when she heard this, "I haven't found out yet, but this smell seems to be acquainted, and I can't remember the root cause for a while."

Dong Dacheng shrugged his nose, "There is some smell of saltpeter sulfur, and the alchemist likes to fiddle with these things the most."

After saying this, Gu Qingyi suddenly realized that no wonder she smelled familiar before. Isn’t this the weakened version of the fireworks? It’s just that this smell is not very authentic and has a strange smell, so she couldn’t remember it.

When Dong Dacheng said this, Gu Qingyi felt it was very similar. It was true that these things were mixed together and it was easy to emit black smoke.

There is no gunpowder in this time and space, and there is only a group of people who pursue immortality to refine alchemy. There are often things to refine alchemy and fry the furnace, so it is easy to get some of this thing and emit black smoke.

Gu Qingyi's mouth twitched, which was really unexpected.

Gunpowder, she knows how to do it, but she doesn't know the proportion. If this thing is not done well, it will be really fatal.

After she has rich money, she can give it a try, mainly looking for professional talents.

She remembered that in the history of the invention of gunpowder in history books, there was a talented man from the Wei and Jin Dynasties who focused on alchemy and was very obsessed with elixirs. If he could find the Ge family, I wonder if he could make gunpowder for her.

However, Gu Qingyi is just thinking about it now. Even if he can find a suitable gunpowder formula, the technological level of other aspects of configuration cannot catch up with it. It is really a toothache.

For example, if you want to build a shell, you have to have artillery fire. How to make the material of the cannon barrel? This is a very fatal problem.

The progress of an era does not refer to a certain aspect, but to take a big step forward in all aspects of the whole society.

Gu Qingyi felt that she didn't have that much energy now, so she could only imagine it in her mind.

Since you have found out the reason, it will be much easier to follow this line and search down.

From the craftsman who came into contact with clay, to the craftsman who was under the head and clay, to the person who picked clay, they quickly found the craftsman who was trying to do something.

When the man confessed that the person behind the scenes was Wang Zhengxin and Gu Qingyi sent someone to capture him, he realized that he had fled privately.

Yes, I left my family and ran away by myself.

Gu Qingyi was shocked. Unexpectedly, the slave dared to escape privately. He listened to Dong Dacheng saying: "Girl, be sure to capture Wang Zhengxin's family. Once Wang Zhengxin escapes, these people will inevitably become distracted. There are also several craftsmen who are accomplices of Wang Zhengxin, just in case."

Although Gu Qingyi doesn't like sitting even, there is no other way at the moment. She will control the person first, so she nodded.

Dong Dacheng got the approval of Girl Gu and took people to arrest people himself, and the entire inside and outside of the fort was shocked.

Yang Bao and others didn't say anything for a long time. Since their young master returned to his hometown, he obeyed the young master's instructions before leaving, and took his people to open up the land and never stopped. Therefore, he did not dare to interfere with the matter in the fort. However, he knew that something happened in this period of time.

Yang Bao was panicked, afraid that something big happened to the fort, and they became rootless duckweed again. In addition, the girl was kind to them, Yang Bao threw down his hoe and went to find out the news.
