Do You Deserve to Be Called a Professional If You Follow the Rules?

Fang Ye traveled through time. In the familiar modern world, countless strange 'doors' appear. The endless army of alien beasts is like a devastating disaster, leaving the whole world in pieces. Professionals came into being, and people awakened into familiar professions such as warriors, swordsmen, priests, mages, and warlocks. Their extraordinary power resisted disasters and cleared the 'door'. When all the 'doors' in the world have become disasters, the door in Fang Ye's mind has become a path to another world and a different 'career'. … In the S-class 'gate'. During the crusade against the World-Destroying Demon Lord, several S-level professionals were helpless. Fang Ye's figure suddenly disappeared into the shadows. The Night Assassin took action, the Ghost Swordsman slashed wildly, and the Shadow Ninja transformed and distanced himself. The sharpshooter, mages, and disaster warlocks opened fire, and the Necromancer and Summoner summoned the army of followers. A priest's great healing spell covered the scarred human crusade. Countless professionals were stunned. What is your profession?
