The Wife I Bought with Two Spirit Stones Turned Out to Be the Demon Sect Empress

[Single female lead + Tsundere Empress + Duplicity + Sweet romance + Daily life + Gradually growing love + Lots of interaction between the male and female leads] A slow-paced story, the male lead isn't a cool, overbearing Dragon Aotian. Chen Jia's daily life as an immortal: refining elixirs, cultivating, and raising a wife. Chen Jia hits the jackpot, having traveled two and a half years. The system finally loads, but unlocking it requires a Taoist partner with a score of 80 or higher. After three days of searching, he finally finds a wife with a score of 99 in the slave market. After a fierce exchange of words and haggling, he buys her with two spirit stones. Who could have imagined she'd turn out to be the Demonic Empress? Murong Qingli: "He's just my cultivation furnace. I'll kill him as soon as I recover." "Hubby! He's quite sensible. When my cultivation recovers, I'll give him a chance and end it all." "A daughter can't be without a father. I'm keeping him for the time being for her." "A daughter alone is still too lonely. Give her two brothers and sisters. He's just a tool for me to have children." Finally, Murong Qingli pestered Chen Jia, and said with a seductive look: "Husband, don't look at the children, look at me." Chen Jia: Isn't she the cold and aloof empress who kills without blinking an eye? How did she get turned into a little wife?
