In 2135, the earth became a wasteland. As the commander of the last bastion of mankind, Lin Ye died together with the Beast King in the final battle, but was reborn three hours before the doomsday erupted. In this life, he not only returned with the memories of his previous life, but also awakened the "infinite evolution system" - killing monsters can earn evolution points, which can be redeemed for extraordinary abilities, future technology, and legion summons! While others were still struggling for a piece of bread, Lin Ye had built the first shelter; while the forces were still fighting for the remaining resources, his mechanical army had swept across the wasteland. In this life, he will rewrite the ending of humankind's demise and establish his own wasteland era!
