Be Rean's Trajectory Radiation Journey

Rean is a hero who chooses to sacrifice himself for the safety of the world. When he opened his eyes again, he came to the desolate wasteland of Washington that was waiting for development. After forming a wasteland construction team with the wasteland legend Long Wande, a smart imperial girl, he originally thought that he could temporarily retire and live a leisurely wasteland farming life, and occasionally play tricks to get some loot, and taste wasteland delicacies from time to time. (And Miriam and Crowe returned to him soon after) But the alien spacecraft that always appeared above his head, and the priest in the small dilapidated church who could rub out solar panels and even mechas with his bare hands, all told him that the wasteland world was not simple. Sure enough, he was told not long after that the world of Wasteland and the world of Samria were going to end at the same time! Don't retire, come back and save the world! (Don't worry, after Mr. Li has passed the early stage, he rarely suffers from depression! Isn't the Eight-leaf Sword Master well-earned!)
