On a rainy night in early winter, Mo Bai returned to his apartment after working overtime at the office, but was dragged into a cold mechanical world while sleeping. The system declares: If you cannot escape from the ancient house within seven days, you will definitely die. In the ancient house, there are ghosts from the unfinished wedding hidden under the red silk wedding curtain, wandering paper figures disguised as companions, and ghosts peeping in the darkness are gradually awakening as time goes by. Mo Bai must decipher the secrets of the ancient mansion within a limited time, and at the same time beware of the "alien" among his companions - the unknown existence that sneaks into the human team with the intention of accelerating the group's destruction.
As the exploration deepens, Mo Bai discovers that this mansion is actually related to a tragedy of a dark marriage a hundred years ago. The bride's resentment distorts time and space, and the only help is a mysterious black cat "Ming Ke". Candles, copper coins, cook's clothes... Scattered props are the key to life and the bait for traps. When the countdown numbers jumped crazily, and the truth and lies intertwined, Mo Bai had to face the cruelest choice: trust a companion who might betray him, or fight alone against the gradually resurrecting ghost.
"When the countdown reaches zero, can you see through the true rules of this game?" - Open "Countdown to Eternal Night" and step into a life and death game against time.
