The power of the Wei Dynasty, which had been established for more than 300 years, turned from prosperity to decline, and the situation in the country, which was originally under the majesty of the old emperor, began to have undercurrents. The originally cynical sixth prince Mo Zaiting began to take charge of the army because of the tight fighting on the border. Bai Yixin, the orphan of the former dynasty beside him, also began to establish his own power. Wang Donglin, a newcomer to the Langya Wang family, passed a major exam and entered the political arena. The three people who later became the "Three Kings" played the final grand movement for the Wei Dynasty.
