Hua Qingcheng was obviously very satisfied with Mu Lige's answer, so she tiptoed and kissed his lips, giving him a sweet reward.

For a man and a woman in love, drinking water tastes like drinking honey. They hugged and kissed for a long time before reluctantly letting go because Hua Qingcheng still had things to do.

"Qingqing, just now you asked San Gouzi about the origin of that stone. Is there anything special about this stone?"

"Brother Li, this is not an ordinary stone, but saltpeter."

"Salt?"

"Brother Li, don't underestimate it. Not only can it be used to make ice, but even... even with enough materials, it can be made into powerful weapons."

"Powerful and lethal weapons?"

"Yes, saltpeter combined with other materials can be made into explosives. It's perfect for blasting mountains, building roads, digging tunnels, and hydraulic blasting... Furthermore, it can be used to create extremely powerful weapons, used on the battlefield to kill enemies and defend the nation. But it's also a double-edged sword. Used well, it benefits the nation and its people, but used poorly, it could lead to devastating consequences."

"Qingqing, you...how do you know so much?"

"I...I saw it in a book. Mom has a lot of books, you know."

Hua Qingcheng spoke too quickly and said too many things that did not belong to this era. Fortunately, the person was Mu Lige. Even if her words were unreasonable, as long as she said it, he was willing to believe her.

Mu Lige's heart was already surging with emotion upon hearing this. If he had such a powerful weapon, wouldn't it be even more powerful? He could punish treacherous ministers and slay traitors, even if it meant storming the Zhaoyang Kingdom's palace and taking Su Mu Tianjun's life...

However, as his young wife had said, this thing was so powerful that it was hard to say whether it was a blessing or a curse. After all, a man is innocent until he is found guilty of possessing a treasure. If those in power knew that Hua Qingcheng could use this thing to create something that could unify the world, Hua Qingcheng would probably be in turmoil for the rest of her life.

"Qingqing, I don't care how you know this, but some things can only rot in your stomach and must never be revealed to outsiders, understand?"

"Yes, I will, Brother Li."

Hua Qingcheng gratefully hugged the man who always cared about her.
