Seventh Planet

In the first year of the empire, the world was highly hierarchical, with three kingdoms of gold, silver, and black iron, and on the edge of the galaxy, there was the forgotten seventh planet. As a special officer, he narrowly escaped death in a battle but lost his belief in fighting, so he survived as a teacher on the seventh planet and opened a school. When he went to pull scrapped mechas, he rescued an extremely handsome man, who turned out to be the son of Phezzan, the leader of the self-made leader.
