Arknights: Lord of War

[Time travel + black technology + power development + non-original plot] When Jiang Wei woke up, the Origin Stone in his left hand was growing like crazy, and the arsenal in his right hand was full! Terra? It's just a new battlefield! The scavenger wanted him dead? Try the modified shotgun! Survive in the wasteland, clear the way with red gold! Win over the infected, unite frustrated soldiers, and arm everything with black technology! From Rusty Nail Town to Bolivar, his power has grown like a snowball, and his name makes the old forces fearful! "A single spark can start a prairie fire! The power of a mortal is enough to change the world!" When a natural disaster strikes and powerful enemies surround him, he has already held the antimatter engine in his hand, overlooking all living beings. Under the false sky, his declaration is an iron law: "Those who follow me will prosper, and those who go against me will perish! I have the final say on Terra's future!"
