He succeeds in conquering the city along with his fellow vice general Man Goku and moves on to siege Bayou. Upon sighting the Qin relief army, he orders his men into a line formation to prepare for any attack and notices that the Qin forces are moving to the side instead of charging head-on. He notices the other generals are present and are complimented by Chou Sou on his work with the advance guard.

He is placed in charge of 20,000 men on the left Zhao army and inquires as to the situation surrounding Fuu Ki and his men. When he hears the report, he comments about the "range" of each of the Zhao generals and notes that the Qin dealing with Fuu Ki may be outside his range. Back at the Zhao army HQ, after the retreat, Kou Son states that the Fuu Ki Army was stronger than that of the Qin as they only lost 1,500 men whereas the Qin lost 8,000. On the third day of battle, his army moves to the center in order to support the Ri Haku Army considering their defeat at the hands of Qin General Mou Bu the previous day.

On the fourth day of battle, his army stands ready for Mou Bu's charge and he is shocked when the other Qin armies begin to move, noting that their aim is Chou Sou and the Zhao Headquarters. After hearing of the decision to move their HQ, Kou Son Ryuu realizes that Chou Sou must have something else planned, and his army must conserve their fighting strength. His army sets up camp on the eastern high grounds after the HQ is relocated and he meets Chou Sou there, asking the strategist about the situation involving Hou Ken's disappearance. Chou Sou tells him that Man Goku went after Hou Ken and none of the other armies can move due to the difficult terrain.
