Saltpeter can be used as medicine and can cure diseases, and it is also a common thing. Not to mention sulfur and charcoal, it is very common. The three kinds of things are mixed together, and they can't imagine gunpowder that they can't imagine if they want to break their heads. Otherwise, it's impossible to be surprised.

Chen Wanrong understood their thoughts: "This is the wonder of chemical engineering. Things that seem irrelevant will be unexpectedly changed after chemical processing. This gunpowder is just one of them."

"We are well-known for the Chen chemical industry. I didn't expect it to be well-known and it has such a wonderful thing." Kou Yibing kept touching his beard and sighed with a smile.

Not to mention him, even Sima Chengzhen, who is extremely skilled in cultivating his mind and nature, is not impressed by chemical engineering, and is willing to follow Chen Wanrong to do chemical engineering.

Ye Tianheng put the crutch and said excitedly: "Okay, let's make it. I'll make saltpeter. Let's make it ten kilograms first, and it's only seven and a half kilograms of saltpeter." He weighed seven and a half kilograms of potassium nitrate and put it aside.

"I'll make sulfur." ​​Kou Yibing said, saying a pound of sulfur and poured it next to potassium nitrate.

Liu Huaide said one and a half pounds of charcoal and poured them together: "Mr. Chen, is this mixed?"

Chen Wanrong nodded and said, "Yes! You must mix evenly."

"No problem!" The three of them said in unison, rolled up their sleeves, and mixed them with their hands.

In fact, there is no need to use hands, but you can use tools. Chen Wanrong wanted to stop him, but he didn't have time and had to let them go.

The mixing process was very simple, but the three of them were very serious, with a solemn look on their faces, and after a while of mixing, they were finally ready.

Looking at the black gunpowder, the three of them could not hold back and even said in unison: "It's time to give it a try!"

Ye Tianheng smiled and said, "I secretly took two of them out, which came in handy."

Chen Wanrong teased: "Master Ye, okay, you are really not interested."

Ye Tianheng was so happy that he said with a smile: "Small things, small things. From now on, I will do as much as you want." He patted his chest and actually made a promise.

"Go and get it!" Kou Yibing urged him.

Chen Wanrong shook his hand to stop it: "It's not possible to try now, I still need to be a fuse."

"The fuse? How to do it?" Liu Huaide felt very sorry and complained: "Mr. Chen, you are really good. If you don't say it earlier, we will have to wait again."

Chen Wanrong smiled and said, "The gunpowder is not good, and I can't do it even if I want to. It's easy to make, just get some cotton thread, oil, linen and moisture-proof agent."

"Oh, there are so many of these things." Kou Yibing didn't take it seriously and walked out of the house. When he turned around, he brought all the things he needed.

Chen Wanrong soaked the cotton thread in oil, then dragged it on the gunpowder and put it outside to dry. Kou Yibing and the other two acted as usual. Looking at the fuse that had not yet dried, Ye Tianheng was anxious: "Oh, my friend, are you okay? You're so anxious!"

Chen Wanrong smiled and said, "Master Ye, don't worry, you can see it. Master Ye, now the gunpowder is ready. You can say that everything is ready for the cannon. Only the east wind is needed, and your cannon is missing."
