When you work overtime at night and encounter the "knock on the door at midnight", the strange realm descends and the rules are dead.
Lin Che, a 26-year-old office worker, accidentally bound the "Netherworld Wallet" and held unlimited Netherworld Coins - the only key to breaking the game in the mysterious realm.
The copy contains a curse, but the evil ghost abides by the rules? The underworld coins bribed the messengers of the underworld, tampered with the laws of death, and found a way out of the loopholes in the rules.
From the terror in the old city to the raging in the mysterious world around the world, he used reason to solve puzzles and used Hades coins to build barriers to connect the human society and the underworld forces.
