Doomsday Game: Krypton Breakthrough System at the Beginning

The whole nation was unexpectedly involved in a doomsday survival game in which only the final winner could survive. While all players were frantically honing their abilities and scrambling for a chance of survival in a desperate situation, only player No. 99 Lin Yunxi predicted the start of the game a year in advance. With his top financial resources and extraordinary foresight, he secretly built an impregnable survival fortress deep in the ocean far away from the mainland, and calculated all foreseeable crises and variables in advance to the extreme. But when the doomsday comes as scheduled, successive natural disasters sweep across the world, and the greed and madness of human nature in desperate situations are completely exposed.
