Li Qianyi traveled through time and became the crown prince of Yanbei, but was framed by Princess Yong Lin Ningyan at the beginning. He turned back an army and turned danger into safety. He angrily denounced and kissed the prime minister in the court, which was appreciated by the emperor. He recruited an oiran, a corrupt official, a counselor, and a sharpshooter, and married Lin Xian'er, the daughter of Duke Zhao. He exposed that King Duan was endorsing the enemy and King Yong was scheming to rebel. Finally, he led his army in the Northern Expedition, became a marquis and took power, and enjoyed the blessings of his people.
