Qin Chuan, a modern man, is reincarnated in the womb as the Sixth Prince of the Great Qin Dynasty. He commands an army of 300,000 soldiers and possesses a Favorability System that rewards him with explosive technological advancements. When the Emperor attempts to seize his military power through an arranged marriage, Qin Chuan plays along, publicly surrendering his military command token while secretly leading his troops in a military demonstration to force the Emperor into becoming a powerless puppet. From then on, he steadily advances toward the throne, deposes the Crown Prince, exterminates the family of the poisonous Empress to avenge his mother, and brings beautiful women into his household to maximize their favorability. With system rewards such as repeating crossbows and refined salt, he amasses wealth beyond the empire's measure and wins over powerful generals. He then suppresses rebellions by the Eastern and Western armies on two fronts with remarkably few casualties, incorporating the defeated troops into his own forces. With no enemies left inside or outside the capital, Qin Chuan is finally ready to become Emperor. This is a story about an Emperor who wants to take away his son's military power, while his son wants to take the Emperor's entire kingdom.
