In the era of national awakening, those with healing powers are known as strategic national treasures, and 99.9% Of them are women. For this purpose, the official established the "Holy Angel Auxiliary College", the highest institution of higher learning that only admitted girls.

Looking at the 1.85-Meter-tall muscular man in front of them, all the girls in the school fell into deep thought: Do you call this a wet nurse? Faced with doubts, Su Bai took out his octagonal sledgehammer. "Manic? Give me a physical hypnotic spell and I'll keep you safe until dawn!" (Bang!) "Comminuted fracture? Watch my amputation and rebirth method and give you a mechanical ascension!" (Crack!) At the national competition, when other female assistants were singing Holy Light in the back row; Su Bai charged forward with a sledgehammer and smashed the head of the abyss beast with one hammer. The entire audience went completely crazy: "I asked you to increase your health, how dare you save all the monsters?!"
