Aji, the waiter in an ordinary shop, lived a poor but stable life in the shabby but inexplicably sturdy "Yelai Inn". A few days after the old shopkeeper mysteriously disappeared, a night came that overturned his cognition. First, Taibai Jinxing, a "successful man" wearing a crisp black suit and smoking a cigar, came uninvited. With a gesture that could not be refused, he forcibly bound the ignorant Aji as the "only designated shopkeeper and chief waiter" of the inn with a "labor contract" flashing with a strange red light. He also buried a ticking "blood contract countdown" mark deep in his soul that only he could vaguely sense.
Before Aji could recover from this weird "entry ceremony", the dusty corridor deep in the inn filled with 999 strange doors suddenly lit up! Countless rays of light from different universes, different dimensions, and exuding different auras instantly flooded the inn. Aji's worldview was completely shattered at this moment - the shabby inn where he worked turned out to be a super transportation hub connecting all the worlds!
