Waking up, Northeast barbecue restaurant owner Zhang Tiezhu became the most aggrieved puppet emperor of the Dayue Dynasty. The Empress Dowager holds him back, powerful ministers sideline him, and the court officials all harbor malicious intentions. Amid the dangerous situation, only Imperial Eunuch Cao, planted by the late emperor around him, closely guards him and follows him with ultimate loyalty all the way. Yet Zhang Tiezhu refuses to accept his fate: in the court, he slams the table to establish his authority, ferreting out corrupt officials and investigating old cases; outside the palace gates, he reorganizes the imperial guards and foils assassinations; with the common people suffering, he opens the granaries for disaster relief and re-establishes new laws. When civil officials use rules to block him, he snaps back with Northeastern dialect; when blades are directed at his beloved, he personally protects her to the very end. From a puppet at everyone's mercy to a true emperor who holds supreme power alone.
