Rimu Dynasty, Kingdom of chaos. Demons were rampant, and it was difficult for people to live.

Gu Qing’an had not yet had the opportunity to appreciate his beauty upon transmigrating in this world, as he had to face the demon who targeted and devoured humans.

Fortunately, she had a system.

“I, Gu Qingan, have never been weaker than others. System, add it to me.”

……

Many years later, Gu Qing’an, standing on the frozen void, looked at the newly discovered strange world under her feet without any expression.

- Description from Novelupdates

Liola—the best assassin in his world—has vowed to kill no more. He was being chased by an assassination organization when he accidentally dropped into a parallel universe: through a dimensional gate and into poor teenager Kaiser’s apartment. Instead of going to the government shelter for lost dimensional travelers, Liola and Kaiser wind up going to school together.

Liola has been trying his best to live the life of an ordinary person, but after certain things happen one after the other, he begins to realize that being an ordinary person could be harder than being an assassin.

Alzi had a promising future. At seventeen, the Goddesses blessed her with a life affinity—a rarity for commoners in a small village; a few days before the class-choosing ceremony, her Mother gets sick. After using her little mana to keep her alive, she runs to the capital to find a true healer. With no money, she sells herself into slavery for a decade. The decade is almost up, but she has been turned into a broodmare for the nobles and faces a sale to keep her enslavement going.
