Lu Qing traveled to the end of the Western Jin Dynasty. After he kowtowed, his husband died. He was just about to take his cheap son to farm.

Pa! A letter of appointment with the official seal flew over, smashing down right on top of the ancient military marriage! Hey, hey! Where's the promised farming? In order to survive, she started to make salt, steel, incendiary bombs, cement, and even warmed the bed of some monstrous general so that he could untie his pants … Was Lu Qing, the top student in chemistry, going to accept his fate just like that? Of course not. Lu Qing: "I don't have the habit of using the same man as other women. As long as you dare to look at another woman, you'll definitely have a couple of Mo Xie in the steel furnace!" Yu Mingchuan said: "What a coincidence, your husband also doesn't have the habit of giving himself to different women. Madam, please use it well and don't waste it. As for the Young Master Xue of Hedong City or the prince of Liangliang Country, do you think you still lack two portraits?"

I find the plot pretty exciting
