[Class Change for All + Everyday Life + Relaxed and Easygoing + Face-Slapping + Comedy + Slacking Off + Immortality]
[Swallow equipment to level up, slack all the way to the top.]
[Turns out I'm the strongest BOSS after all.]
The first 80 chapters have a little frustration and everyday life, but once he reaches the top instance, he rises to power for good.
Amid the class-change craze, Lin Ge unexpectedly transmigrates into another body and discovers that his original self had a trash profession, pastry chef, and has been slacking off for five years while looking after his family museum.
Lin Ge's transmigration also brings him the only hidden profession: Immortal.
Everyone else has to grind through instances to level up, but Lin Ge doesn't. He enjoys his laid-back life, lounges around earning a few gold dragon coins each day, then collects equipment and converts it into experience points, all in one convenient package.
Lin Ge has multiple professions, which also means multiple attribute bonuses. Only when he reaches level 100 do people realize that the pastry chef who once ran a museum was the ultimate BOSS.
It's quite toxic, but I still have to say, come on, author.
