Zheng Yun, who struggled until middle age, originally thought that he could finally live a carefree life of playing games and watching TV shows every day. Who would have thought that he would wake up in a different world, and what's more terrible is that the other world is still in the end of the world!

Launched a surface-to-surface missile and it fell before we even met! Senior professional? How long can your elemental barrier hold up under fire coverage?
