Leguna. An orphan. His life changed dramatically the day the thieves’ guild happened to select him for training and development. He would go on to become lifelong friends with a loyal mercenary, the partner of a beautiful magus who was cold as ice, the savior of a mysterious disfigured dark-elf girl with a talent for the Breath, and the unlikely caregiver for a feisty young maiden. And yet, who would be with him to the very end?

Wei Qiqi is the only successor of Wei Corps inheriting a hefty fortune. However, her stepmother bribed a witch from Thailand, harming her with two ancient witchcraft curses.

Qu Mao, who hadn’t had time to cut his sister out of class and experience the degenerate university life, woke up and found that he had come to a strange and cruel new world, and it seemed that young people from all over the world came to this world together…

The world channel was full of shouts and curses. Except for a tattered lord’s order, everyone didn’t even have a whiteboard novice weapon at the beginning…

But Qu Mao is not worried or in a hurry, because he has a cheating system with him, and he just wants to save some cheating points. With cheating points, he has everything.

Who would want to cheat if they could win by cheating?
