Dai Xuan is an ordinary sophomore
Together with a group of buddies, he signed up for a tourism project called "Explore the Mysterious Old House". After a long journey, Dai Xuan was surprised to find that the so-called mysterious old house was actually the old house that his grandfather sold after his death.
I originally thought it was just a coincidental game, but after everyone entered the old house, the strange door automatically locked, and ten people were locked in this empty room...
