Lu Yan, an ordinary social worker, was swept into the "fate contract space" by a strange black mist on his way to get off work, and he fell into a seven-day cycle of death. The rules of space are cruel: team up to solve themed puzzles, fight against the pursuit of the contract owner, and beware of betrayal by teammates. If you fail, you will be devoured and your memory will be permanently erased. Fortunately, Lu Yan awakened the "Destiny Recall" ability, which can reverse key nodes, but at the cost of his life force.
From the mystery of ghosts in the ancient mansion of the Republic of China, to the AI siege in the cyber city, to the ancient secrets of the ancient desert city, every round is full of dangers. Teammates have their own thoughts, high-dimensional observers are spying secretly, and the "Shadow of Nothingness" that devours consciousness is watching covetously. Lu Yan relied on his backtracking ability to superimpose information and outwit all forces, only to discover that there was a screening conspiracy of ancient civilization hidden behind the space, and he was actually the key to fighting the Shadow of Nothingness. This life and death game is no longer about survival, but the final battle to break the cycle of reincarnation and protect reality and civilization.
