Professional Fusion: I Am Supreme in Tampering with Knowledge

Traveling to a world where "profession" is respected, Gu Heng woke up with a mysterious [Palace of Knowledge] and became a seemingly powerless hidden profession - [Scholar]. While others were exercising their bodies and practicing spells, he interpreted the rules and gained insight into cause and effect. In this world, professions can be integrated and advanced: two professions can be merged into a more advanced profession, [Savage] + [Politician] = [High Priest]; [Farmer] + [Guard] = [Scarecrow]... A road of fusion paved with knowledge unfolded at his feet. It wasn't until that day when a whisper came from the depths of the palace that he realized that all his growth seemed to be under the watchful eye and calculation of a certain being... Now, what he wants to do is to use the "error" he made in his epiphany to tamper with the "correct" ultimate ending set for him.
