In the cold cage called the "Lord God Space", countless souls from different time and space were forcibly recruited. They must travel through dangerous worlds - the academy where zombies are rampant, the Soul Society where Death and Hollows are raging, the Ninja World where ninjas fight, the Grand Route where pirates are separatist, and complete the brutal tasks that follow in order to exchange for the right to survive. Every mission is a gamble of life and death, and every choice affects the bottom line of human nature. The protagonist Lin Chen, an ordinary college student, was accidentally involved in this game. After struggling with fear at the beginning, he gradually learned to sharpen his will and make companions in desperate situations. In the bloody battles, he got a glimpse of the secrets hidden behind the space that were far beyond imagination. When he led the survivors to complete the last task, thinking that they could finally break free from the shackles, he woke up in the dazzling white light - it turned out that the so-called Lord God Space was just a long and real nightmare.
