From Helping the Cold Campus Belle Wash Her White Stockings to Sweeping the High Martial World

[Invincible + Ruthless and decisive + Power fantasy + Sword Dao + SSS-rank] Su Yuan woke up to find he had transmigrated into a high-martial world under attack by ferocious beasts! With an E-rank nimble-fingered talent, all he could do was become a laundry worker at Saint Martial Arts University, scrubbing people's clothes! Just as he was about to wash the school belle's white stockings, the Laundry System awakened! As long as he washed clothes, he could gain their owner's abilities! He also had a chance to randomly receive a 1-to-10,000-fold critical bonus. [Ding! Congratulations, Host, you scrubbed Yan Xueling's white stockings. Thousandfold critical bonus: obtained the SSS-rank Ice Age.] [Ding! Congratulations, Host, you scrubbed a pair of black-stocking battle tights. Ten-thousandfold critical bonus: obtained the Heaven-rank martial art, One Sword Opens Heaven's Gate.] [Ding! Congratulations, Host, you scrubbed a JK maid outfit. Ten-thousandfold critical bonus: obtained the SSS-rank superpower, World-Destroying Divine Thunder.] [...] With every load of laundry he scrubbed, Su Yuan grew stronger! Years later, as Su Yuan looked down at the myriad races of the heavens and the universe's gods prostrating themselves on the ground, he lowered his hand with a benevolent smile: “Wouldn't it have been better to surrender sooner?” A casual sword stroke shattered space, reversed time, wiped out countless races, and destroyed billions of lives!
