Su Wen never thought that he would become a leader of civilization. He just looked at the summoned mythical version of Xiang Yu in front of him. He was so powerful that he pulled up the mountain and threw it out. Well, to be precise, he really pulled up the mountain and threw it out. This was enough to defeat the conventional modern army. So what kind of existence was Han Xin who beat Xiang Yu back then? Looking at the interstellar empire with spaceships in front of him also reminded Su Wen of the era surrounded by darkness - the Stone Age!
