Meteorite from the End of the World

A meteorite from a higher civilization broke through Iwakaze's ordinary high school life and opened the door for him to travel between two worlds. On one side is the apocalypse of the alien planet where order has collapsed and is full of crises, and on the other side is the modern Blue Star that seems peaceful but has undercurrents. Yanfeng's only capital is the ability to travel between reality and the end of the world. When the resources of the two worlds begin to circulate through him, every step Yanfeng takes is related to the future of the two civilizations - can he rebuild order in the wasteland, and can he make Blue Star's technology usher in a leap?
