The DoDo adventure team received an unsigned letter containing five plane tickets to Sydney, Australia.
In Sydney, they were commissioned to arrive at an alley that looked deserted for a long time.
A legend learned from an old man makes the alley scary.
And this just inspired the DoDo adventure team's enthusiasm for adventure.
The wind blew through the weeds at the entrance of the alley, revealing a stone slab engraved with a puzzle.
The suicide song that sounded in the middle of the night caused Charlie and Fuyou to encounter a blond girl who claimed to be the Mystery Solver of the Floating City.
The truth about the "alley suicide" incident many years ago came to light through their joint efforts.
All this comes from a bet between two prominent families.
If you lose this bet, you will sell your soul to the devil and you will never recover!
