Earth Immortals are cultivated from a blessed land.

High school student Mikoshiba Ryouma was summoned to a different world in the middle of a war. Sensing the malice from the one who summoned him (a summoner of the O’ltormea empire), he uses his martial arts to run away, killing important people of the empire during his escape. After the escape, he rescues two twin sisters from the hands of thieves. The sisters who can use magic, swear to serve him as subordinates. Thus, Ryouma begins his journey on the path of the supreme ruler.

Trying to drown her sorrow with alcohol after her boyfriend hooked up with her sister, Ning Qing ran into the rich and powerful Lu Shaoming in a bar. “I need a wife,” Lu said, and the two got their marriage license.

Ning Qing bristled, “Lu Shaoming, what happened to staying out of each other’s private life which we talked about?” Turning the light out, he came over her and whispered, “Now our priority is to make a baby.”
