### Summary
The tragic, noble death of Prince Sei Kyou serves as the final catalyst, plunging Qin into an all-out civil war between King Ei Sei and the seemingly invincible Chancellor Ryo Fui. The conflict’s first battleground is the King’s own coming-of-age ceremony, a sacred rite that forces him to leave the capital vulnerable at the most critical moment. This vulnerability is ruthlessly exploited not by Ryo Fui directly, but by a shocking third player: the Queen Dowager. Manipulated by her lover and emboldened by a secret army, she declares the independent State of Ai and launches a surprise invasion of the capital, Kanyou, in a mad bid to place her own son on the throne. The political crisis becomes deeply personal as the invasion coincides with the birth of Ei Sei’s first child, forcing him to fight not just for his throne, but for the future of his newborn daughter. While the capital's defenders, led by the brilliant strategist Shouheikun, mount a desperate last stand against the invading hordes, the King’s only hope is a frantic, high-speed charge back to Kanyou, with the Hi Shin Unit acting as his vanguard. Xin, now a seasoned commander, is tasked with carving a bloody path through the rebel army to save the kingdom. The arc culminates in a brutal battle within the palace walls, where the King’s forces make a last stand. The rebellion is ultimately crushed, leading to a heart-wrenching final confrontation between Ei Sei and his mother. This victory, however, is merely a prelude to the true endgame: the final, decisive political confrontation with Chancellor Ryo Fui, whose intricate web of conspiracy is finally exposed, setting the stage for his ultimate downfall and the true unification of Qin under a single king.
