My own summary of the first few chapters. It is pretty spoiler free, compared to the original summary. If you would like to read the translated summary, scroll down and click the spoiler tab.
A fresh graduate gets accepted into a company. In the company, he meets many weird people and many weird things occur. The novel starts off with the MC on the toilet bowl cursing, then flashing back to a year before where he is first employed and gets to know his unique colleagues.
An ordinary run of the mill employee, a recently graduated new employee. An unlucky guy frustrated with life, a nobody always being bullied by his superiors and colleagues. Unexpectedly, a nobody like this obtained a fabled power, a thing of the legends, the celestial arts of the Immortals. He turned into the only remaining disciple of the legendary magical treasure refining sect, the Three Treasure Sect, from aeons ago. With this, he gained the ability to refine all kinds of magical treasures, isn’t that amazing?
