If given a second chance, would you choose to eke out a living, or... forge a new order with your own hands? Xiang Yan struggled for six years amidst the mountains of corpses and seas of blood in the apocalypse, ultimately choosing to jump from the 28th floor to end his desperate life. However, he didn't meet death; instead, in a blinding white light, he returned to the day his nightmare began—in his university classroom. Only sixty minutes remained before the virus outbreak and global collapse! This time, Xiang Yan vowed never to let the tragedy of his past life repeat itself. He would not only survive, but also pull his brothers along to survive! Just as he was preparing to use his precognitive abilities to escape this university town that was about to become hell, the [Final Legion System], which had been reborn with him, was fully activated. It brought not simple personal enhancement, but a cruel and powerful law: using survivors as the foundation, conscripting an iron legion!
