Gu Shanhai quickly found the archaeological team that was preparing to explore the ancient relics and took the opportunity to join them.
Of course, not as a member of the research team, but as... a chef.
With his background, not having studied archaeology professionally, how could they possibly let him join the research team? Thus, it was only natural that he became part of the logistics staff.
Indeed, it was his above-average culinary skills that got him in.
He soon discovered that the current project wasn't classified, just a regular one. Otherwise, he wouldn't have been able to get in.
The reason was simple: they had no idea that such a relic could contain something that would change the times, or else they wouldn't have been so careless.
As for his lack of official registration... he'd solved that, too.
