In order to pursue the truth about his sister's drowning three years ago, Lu Chen accidentally broke into the death cycle called "Seven Days of Cold Abyss". Here, he and other intruders had to go through seven fatal trials such as Greedy Wolf, Shadow Demon, and Mirror Ghost. Only by collecting seven pieces of cold jade can he get out alive. As rounds of cruel escape games began, Lu Chen gradually discovered that this was not only a journey of survival, but also a deliberately arranged conspiracy. He was already the seventh key in this reincarnation.
