The Northern Expedition Purge and the Hostage Trade
Before the army marches north, the court faces clean-up duty to root out Northern Jin spies. Xiao Wuyi and Prince Qi Li Mu trap the spy A-chan, pulling the palace spy ring right out into the daylight. With the informant captured, Xie Jiayu steps up with high-stakes leverage, trading the blueprints of the dangerous artillery device known as Huojilin to secure the release of vital hostages.

Things get grittier out on the frontline. Prince Ying puts Xiao Wuyi through brutal loyalty tests, torturing captured aides to squeeze out the defense maps of the northern border. Xiao Wuyi turns Prince Ying's paranoia against him, negotiating a secret agreement to recover the capital, but Prince Ying drops an even colder ultimatum. Backed by an imperial decree from Northern Jin, Prince Ying drags County Princess Li Luojun right between both army lines and demands that Xiao Wuyi choose her fate.
Xiao Wuyi's Deadly Spy Gambit Between Frontlines
Standing on horseback before both clashing armies, Xiao Wuyi draws his bow and brands himself an open traitor. He denounces Li Mu across the plains, turning his own comrades into bitter witnesses. This move is the classic sijianzhiji, a deadly stratagem where an operative burns his own reputation and misleads his allies so the enemy swallows the bait whole.

Prince Ying suspects everyone, cutting down anyone who wavers for a second. Xiao Wuyi knows mere words cannot buy Northern Jin's trust. By drawing genuine outrage from the Northern Army and firing toward Li Luojun, he leaves Prince Ying with zero room for doubt.

Li Luojun's Poisoned Atonement and Final Choice
Li Luojun carries the heavy weight of earlier missteps that cost countless lives. Instead of waiting for Northern Jin executioners, she secretly consumes a lethal, slow-acting poison in her cell, choosing her own terms of departure.

She visits Xiao Wuyi beforehand, asking him to deliver the fatal strike on the battlefield rather than letting Northern Jin claim her life. Her death seals Xiao Wuyi's cover, offering him the credibility he needs while delivering a stinging wake-up call to her power-hungry brother, Li Mu. Draped in her bold red cloak, she walks between the forces, cutting off her past ties to husband Mu Lianyu and stepping into the arrow's path with quiet resolve.
Xie Jiayu's Hidden Sabotage and Remaining Finale Questions
Xie Jiayu works her own quiet magic away from the vanguard. When handing over the Huojilin blueprints, she secretly alters key structural schematics. Those planted flaws guarantee Northern Jin cannot turn the explosive artillery against their own lines without catastrophic failure, building a backdoor for Xiao Wuyi's survival.

With just two episodes left before the finish line, several massive threads remain up in the air:
- Xiao Wuyi's Shortened Lifespan: Medicinal brews only buy him around two months, leaving his survival very much on the clock after revenge wraps up.
- The Iron Mines and Quegu Order: Prince Ying and Li Mu both hunt for the Zhengfeng Ridge iron deposits, tied to the prophecy that peace follows the Quegu artifact.
- The Mysterious Consort Report: At camp, scouts report a woman claiming to be Xiao Wuyi's consort has arrived at Prince Ying's lines.
