Baishui couldn't understand the conversation between Wei Zi and Yan Xiao, and asked, "What are these white stones used for?"
"It's very useful!"
Yan Xiao found it difficult to explain clearly in words, so he entered key words into his phone and called up a short video.
"Boom——"
Seeing the explosion scene in the video, both Baishui and Qinggui were shocked, not only because of the video itself, but more importantly, what happened in the video.
"What is this, so powerful?" Bai Shui was extremely surprised.
"Gunpowder, black gunpowder." Yan Xiao pointed to the white stone and said: "These saltpeter ores are one of the raw materials for making black gunpowder. However, for 'nitrate, disulfide, and charcoal', you still have to find sulfur...
"
Wei Zi's eyes turned from the saltpeter mine on the ground to Yan Xiao's face, which looked a little startled.
In the ancient tomb in Jiangnan, there are prototypes of modern weapons and various ores, which were left behind by Yan Xiao;
Six hundred years later, black gunpowder also existed in Yun State. On the Lantern Festival night, the gunpowder exploded. She and Feng Danyuan worked together to save the patient... Black gunpowder appeared earlier in history, thanks to Yan Xiao.
The Yun Country she traveled through for the first time had many traces of words and laughter, and these traces were promoted little by little by words and smiles like today.
What about the ending of Yanxiao?
Will it change because of the arrival of her and Feng Danyuan...
A shaking hand interrupted Wei Zi's distraction, and he said with a smile: "Why are you staring at me?" His expression changed slightly: "Did you think of something?"
"'Mononitrate, disulfide and three charcoal', sulfur can also be replaced with realgar. There are several bags of realgar in the medicine library." Wei Zi shook off the inexplicable haze in his heart and returned to the topic.
"Really?" Yan Xiao almost jumped up: "Then what are you waiting for? Let's make black powder!"
"Yeah." Wei Zi nodded.
If we have black gunpowder, it will be much easier for our second brother Wei Lang to dig mountains and open channels, and the speed of water control will also be much faster.

Wei Zi immediately told Feng Danyuan about the discovery of the saltpeter mine.
Feng Danyuan was also shocked.
A few days ago, he and Wei Lang were worrying about opening the mountain. At that time, he thought of black gunpowder, but he didn't have the raw materials on hand, so he had to ask people to find them first, and then start making them after they were found.
I never expected that there would be such a large reserve of saltpeter mine here!
"'Mononitrate, disulfide and three charcoal', potassium nitrate accounts for 75%, charcoal accounts for 15%, and sulfur accounts for 10%... Potassium nitrate must be extracted from saltpeter ore first,
I'm looking for a way to refine it -" Yan Xiao muttered while sitting on the stone, flipping through his phone.
"There's no need to look for it. I've made black powder and I know how to do it," Feng Danyuan said.
Yan Xiao suddenly raised his head and looked at Feng Danyuan in surprise: "Do you know how to make black gunpowder?" Have you really traveled through time?!
Wei Zi had no choice but to help Feng Danyuan explain: "He knew it. As for how he knew it, it's a long story. I'll tell you slowly when I have time."
Yan Xiao immediately turned his head and stared at Wei Zi, his eyes full of gossip: It doesn't matter if it's a long story, I have time, I want to hear it!
"You don't have time, you have to help." Feng Danyuan extinguished her gossip in just one sentence.
