Hearing this, Emperor Kangming and Prince Bai Yishan were stunned.

Both of them know that Bai Yixiu is not mischievous. Hearing Bai Yixiu say so, it can be seen that this matter is very important.

Emperor Kangming nodded, then waved his hand. Four people came out of the dark corner of the room, "you four go out. No one is allowed to come near my study!"

"Yes, your majesty!" four people in black went out and stood on the roof, two, and the other two were below, a few meters away. No one was allowed to approach.

Emperor Kangming looked at Bai Yixiu, "Yixiu, can you say it now?"

The prince also looked seriously at the clever brother. Maybe the brother could bring a surprise?

Bai Yixiu had thought about what to say, "father, emperor, if I can develop a very lethal weapon here, do we have a one-stop battle this time?"

Hearing this, Emperor Kangming was stunned. "What is the most lethal weapon you said?"

"Different from cold weapons such as swords, what I make is hot weapons!" Bai Yixiu replied with a dignified and serious expression.

The prince's white clothes were more confused, "what kind of weapon is the hot weapon?"

Bai Yixiu thought for a moment and then replied, "father, emperor and brother, we will burn something called fireworks on New Year's Eve. They explode in the sky, just a little light!

What I want to do is to increase the composition of gunpowder contained in these things, and then make them have great lethality after ignition and explosion. "

Hearing this, Emperor Kangming's white clothes were stunned, shook his head and smiled bitterly, "how can such lethality hurt people?"

"Yes, Yixiu, you take it for granted. If it could be used as a weapon, it would have been used long ago, and can it wait until now?" Bai Yishan smiled bitterly. This time, there was no humiliating peace talks, or there was a battle with unknown victory or defeat.

Bai Yixiu heard the words of emperor Kangming and Prince Bai Yishan and knew that they couldn't believe it because they didn't see the power.

"Father emperor, brother Huang, can you give me half a month to take people to the mountains to produce and experiment, and then let father emperor and brother Huang see the finished products. In this half a month, you must stabilize the Heichi mission." Bai Yixiu said in a deep voice, with a serious expression.

Emperor Kangming looked at Bai Yixiu and was stunned. "Yixiu, are you serious?"

"Yes, father and emperor, you can trust me once," Bai Yixiu said in a deep voice. "If the weapons are developed this time, we can win the ZTE National Games for Da Zhou for at least ten years. Father and emperor, I can finish it in half a month."

Prince Bai Yishan was even hotter and looked at emperor Kangming. "Father, let Yixiu try it? Maybe there will be our third method here."

Emperor Kangming nodded, "well, every time the mission comes, it will stay in the capital for one month, so you should have enough time to repair. If you can really develop powerful weapons, we can win this time."

"Yes, father, you sent me some people and sent me some things I want in private." Bai Yixiu wrote down a lot of things on the paper.

Emperor Kangming looked, and his heart also raised some hope, "OK, I'll send someone to follow you. Be careful."
