Sixth Prince of Great Qian: System Powers, Success Secured

Transmigrator Qin Ye has been hiding in Great Qian for eighteen years. When he attempts to travel to his fiefdom, the Emperor keeps him in the capital to balance the Second Prince, Qin Feng. After awakening the sign-in system, he resolves the crisis, leverages his power to weaken Qin Feng, and recruits the City Guard Mansion. He cleverly repels the barbarians, shatters Qin Xian's conspiracy, and leads the Qin Wang Guard to quell the Qin Zhan rebellion, saving the Emperor. Finally, Qin Ye is enfeoffed as Crown Prince, expands his territory in the spring, and achieves his empire.
