The battle took place on the southern path to Kanyou, the capital of Qin, in a narrow mountain passage.
Background[]
With the events of the 15th day and Qin's momentum, Ri Boku suggested that the coalition army should withdraw their forces and reconsider their strategy. During the night, Ri Boku secretly departed the HQ with unknown direction, leaving only one request: All army generals should pick 1000 elite soldiers and have them "chased" after his trail. As it turns out Ri Boku had a backup plan to sneak his army through Bu Pass and reach Kanyou. As he was traveling on southern path, his army attacked and conquered any and all small cities and outposts on their way as he sent units ahead led by Kaine.
However, as it turned out later, on the 16th day, Duke Hyou noticed some dust cloud and left his post at Kankoku Pass to chase it thinking Ri Boku was leading the forces. Compared to the Ri Boku Army that had taken a longer and more roundabout route to avoid being discovered by the many Qin outposts in the mountains Duke Hyou's detachment used the advantage of their home terrain to move at full speed while absorbing soldiers from any garrisons they found along the way. Thanks to that they were able to catch up to the Ri Boku Army's rear with a force numbering 5000 soldiers.
Battle[]
In response to Ri Boku's plan to attack the second, less defended entrance of the capital, Duke Hyou quickly flanked the Ri Boku Army. Having noticed this Ri Boku set up Ryuudou to separate the Duke from his soldiers but by using his instinctual abilities Duke Hyou was able to penetrate through to the center of Ri Boku's formation. Meeting each other face to face Ri Boku compliments Duke Hyou's abilities as an instinctual great general but he reveals that the end of the Ryuudou was a trap just in case someone breaks through.
Hou Ken is revealed to be the "trump card" of Ri Boku as he appears. Duke Hyou orders his soldiers to chase and kill Ri Boku while he duels with Hou Ken, Duke Hyou is overpowered most of the fight and when he hears Shin screaming his name he threw his Shield at him tells him to go FORWARD towards Kanyou. Duke Hyou then lost his arm to Hou Ken, but he later proceeded to break Houken arm and told Shin “don’t ever let your fire die out” before he’s slain. His adjutant Gaku Ga also lost his life and the remaining 2000 Qin soldiers retreated towards Sai and lost even more numbers from being harassed by Zhao pursuers.
Aftermath[]
After Qin army reached the city of Sai, they met the Ei Sei Army and their King, Ei Sei. The Zhao army soon followed after and the Battle of Sai began. Years later, it was revealed from this clash that Ri Boku was able to deconstruct and decipher the mechanisms of how Instinctual type generals wage war. This led him to begin his own awakening as a Hybrid Type and create his own hybrid army.
