Shi Yan was trapped in an endless loop of options. Every time human beings will perish after the 99th option comes, and all he can do is delete one of the options, and then the world will die again in a different way. On the 100th restart, his deletion permission mutated into "time editing": to delete an item, a new cause and effect must be filled. Shi Yan finally understood that the real way to survive was not to delete the disaster, but to use the options accumulated through 99 reincarnations to reversely write an ending into the system. While the world's strongest players were still fighting for the "end of race" option, Shi Yan had quietly changed the last line on the option list to - "Host: the system itself, countdown starts."
