The modern time traveler Zhu Lian accidentally transformed into Emperor Chongzhen. It was only nine days before Li Zicheng conquered the capital. The Ming Dynasty was in a desperate situation. Corrupt officials were in power in the court. The old and weak in the capital were in lack of pay. Guan Ning's cavalry was attacked from both sides. The plague in the capital was still lingering. He abandoned softness and used an iron fist to break the situation, kill Wei Zaode and other corrupt officials to establish his authority, and confiscate his family to raise millions of military pay. He also used Li Banghua's strategy of moving the prince southward to win over military generals and withdraw the prison troops to stabilize the morale of the army. He also joined forces with craftsmen to improve firearms and develop grenades to prepare for war. Faced with the assassination and the threat of nobles, Zhu Lian refused to give in, and worked step by step during the nine-day countdown, vowing to save the precarious Ming Dynasty.
