The Earthlings Who Went to War

One day, in some year and some month, when no one even knew how many stars there were in the universe... Earth's people were forced to go to war, becoming reinforcements for worlds facing apocalypse. No need to pilot a spaceship through the stars. You only had to be eighteen. Everyone transmigrated, conscription was mandatory. As soon as adults fell asleep, their consciousness was projected onto different planets, where they helped the people of other worlds resist the onslaught of doomsday. From then on, no one dared feel sure they would see the sun rise the next day. Every cloud has a silver lining: being forced to do the job did come with some compensation. Besides receiving a unique second life, everyone from Earth earned a reward each time they saved a world from destruction. And yet, 200 years later, the number of rewards Earth had earned was still zero... On the planet Harkmandania, Xie Wange became a pure support priest through “a moment's carelessness.” What path lies ahead for her?
