Hashoku Tensei (Worm/Celestial Forge SI)

A guy sets out for his first day at work. Halfway through the journey, the job description and location changed. His Mom did say that a job in the Sales department was the hardest one he could find. Maybe saving his new Local Multiverse from its eventual destruction would be easier? In case the title seems familiar to you then, yeah it was made after I read some Mushoku Tensei fanfiction. Now the title is pretty straightforward to translate, "Hashoku Tensei" or "Hatsushoku Tensei" can roughly mean "First Job Reincarnation". Obviously, it won't make much sense to you without context, but it was a fun little idea I had for an SI so I'm going with it! *NOTE: THIS IS BEING CROSSPOSTED ON SpaceBattles, Sufficient Velocity and Questionable Questing.
