Unexpectedly, Rong Chengxuan not only understood it successfully, but also changed a few places that Yun Wanwan had always felt was inappropriate.

Rong Chengxuan held Yun Wanwan's hand and added a few troubles to the paper: "Do you think it will be better like this?" ”

Yun Wanwan's eyes lit up when she looked at the few places that Rong Chengxuan had changed, and exclaimed, "Rong Chengxuan! Do you know? If you're with us, you're going to be called a genius!" ”

Rong Chengxuan put down the hand holding Yun Wanwan and smiled lightly, "Actually, there is also research in the East and West Army, which is called explosives, but we have experimented several times without success, so it was temporarily stranded." When they were researching, I also went to observe it a few times, so I learned some principles, and I saw your drawings today by mistake. ”

Yun Wanwan also put down the brush in her hand and showed the drawings she had drawn to Ge Zichen and Xiao Song, "What do you think?" ”

Ge Zichen and Xiao Song lowered their heads and studied for a while, and finally came to the conclusion that they couldn't understand this drawing, but listening to the prince and the princess, if the things on this drawing could be made, then the Western Zhou army would only be beaten by them standing up.

Ge Zichen and Xiao Song raised their heads and said in unison: "The subordinates are all under the command of the prince and the princess!" ”

Yun Wanwan looked up at Rong Chengxuan, there was indescribable excitement in her eyes, if she could really study gunpowder and bombs, then Beichen would be an invincible existence in the future. Even if he didn't have Rong Chengxuan personally in charge of the army, he could still win the battle.

Yun Wanwan didn't know before, it turned out that when Rong Chengxuan went on the expedition, he had to deal with the twists and turns of the fast horse coming from the capital, and these days, Rong Chengxuan would only come to the room every day when he arrived.

"Rong Chengxuan, after I make gunpowder and bombs, can you allocate 200 people for me?" Yun Wanwan tilted her head and gave him a number, "These two hundred people must be clever, and I will personally teach them how to use these gunpowder and bombs." ”

As soon as Ge Zichen heard that Yun Wanwan was going to teach people to use this extremely explosive weapon, the first one couldn't sit still, pointed to himself and asked Yun Wanwan: "Princess Niangniang, do you think I look smart?" ”

Xiao Song put his hand on Ge Zichen's shoulder and poured a basin of cold water on his head, "Forget it, I'm afraid that if you learn this, the next time you train those recruits and see that they don't like anything, you will directly blow up the entire battalion with gunpowder." ”

Ge Zichen hurriedly pushed Xiao Song off his body, and hurriedly defended himself: "Princess Niangniang, don't listen to him smearing me here, he just saw that I was too clever and didn't want me to learn from you, so he said this." I don't lack anything else, but the most important thing is to be clever and steady. ”

Xiao Song was forcibly banned by Ge Zichen covering his mouth, but he still didn't miss the opportunity to mock Ge Zichen. He snorted lightly to express his disdain, and the expression on which he looked at Ge Zichen from above was full of mockery. That's better than what I just said.

Yun Wanwan was amused by the scene of the two chickens pecking each other, "I still listen to your prince about the affairs of this army, if you want to come and learn from me how to use gunpowder and bombs, you should go and tell your prince." ”

Compared to Yun Wanwan, Rong Chengxuan is not so easy to speak, when Yun Wanwan said that he wanted them to talk to Rong Chengxuan, the two of them were immediately silenced, and then obediently stood aside and listened to Rong Chengxuan and Yun Wanwan discuss how to configure gunpowder and explosives.

By the time Yun Wanwan had drawn the design again, it was already completely dark outside. Ge Zichen and Xiao Song have been waiting by Yun Wanwan and Rong Chengxuan because they didn't have Rong Chengxuan's order.

When Yun Wanwan rubbed her neck and looked up, she saw Ge Zichen and Xiao Song still standing there, "When I was drawing with Rong Chengxuan just now, you two have been standing here?" ”

Xiao Song replied: "The prince has no clear order, so his subordinates dare not leave. ”

Yun Wanwan glanced at Rong Chengxuan, he was still staring at the drawings on the table, obviously not taking their conversation to heart, so he waved his hand and told them to go back first, "When this happens again in the future, you tell me to go down and rest first, when Rong Chengxuan and I are busy, it is easy to forget myself, and there is nothing that needs to be served by someone's side." ”

After Ge Zichen and Xiao Song responded, they said that they all knew, so they listened to Yun Wanwan's words and went down first.

Rong Chengxuan added a few more strokes to the drawings before he raised his head from the table, looked around, and found that Ge Zichen and Xiao Song had already left, and then looked at the sky outside that was completely dark, "It's so late?" ”

"Hmm." Yun Wanwan stretched, "I saw that it was so late, so I first asked Du Yuhou and the left guards to go back and rest first." ”

As he spoke, Yun Wanwan walked in front of Rong Chengxuan and picked up the drawings he had just finished, "Then I'll be going to make these gunpowder and bombs tomorrow." Yun Wanwan calculated the time in her heart, "If you give me about ten days, I should be able to make the amount needed on the battlefield." ”

"Ten days?" Rong Chengxuan frowned unreachably, "Is such a short time enough?" Would you like me to find someone to help you make it? ”

Yun Wanwan shook her head and rejected Rong Chengxuan's proposal, "No, these production processes are a little unskilled or unsmooth, and those will kill you." Even I have to be careful, let alone the craftsmen I haven't come into contact with. ”

Yun Wanwan's words are all reasonable, and Yun Wanwan herself dared to make these things because she was still in contact with these things in modern times, so she dared to make these with Rong Chengxuan. If this is replaced by Xiaobai, who doesn't know anything, don't hurt your own people by mistake before the gunpowder bomb is made.

Rong Chengxuan also knew that what Yun Wanwan said made sense, just like what Yun Wanwan said, even she had to be careful when making this thing, not to mention those craftsmen who were still white, Rong Chengxuan rarely continued to insist on his own ideas.

"In that case, let's go back and rest first, and put the rest here first, and I'll clean up after I come over tomorrow."

"Wait." Yun Wanwan stopped Rong Chengxuan, who was about to lead him out, picked up the brush on the side, quickly wrote down a few things she needed on the paper, and handed them to Rong Chengxuan, "These things are what I want to use tomorrow, if you can, can you have someone prepare them for me tonight." ”
