Interstellar Legend: the Rise of the Emperor

The protagonist Qin Jie lost his father and mother when he was young, and he was dependent on his seriously ill sister. By chance, his sister merged with the most powerful "intelligent brain" in the universe, becoming Qin Jie's biggest help in fighting for the hegemony of the universe. The five major powers of the universe, Guangming, Canglan, Beiming, Weir, and Wuluan, fought openly and secretly, and eventually the Second Cosmic War broke out. It also created opportunities for Qin Jie, who joined the army, to compete for hegemony, including recruit training, gladiatorial competitions, auctions, starship hegemony, confrontation between the two armies, and technological blessings. A generation of emperors rose rapidly under the cultivation of three mysterious instructors. With the help of A1, Yanagawa, Zhang Ying, Yige and "orphan officers", Qin Jie brought robots, slaves and aliens under his command. Occupying Wuluan, destroying Weir, and pacifying Beiming, step by step he established his own new order in the universe. The final battle with the light became Qin Jie's interstellar legend.
