Summary[]
Continuing his duel, Shin calls for Bi Hei. He tries to hit Gaku Haku Kou with his podao, but the Zhao Duke dodges every attack while countering. Shin is blown away and lands in Bi Hei's arms. The Zhao soldiers are surprised that Shin can even react to the Duke's "Vanish" technique. Shin decides to entrust Ou Ki's podao to Bi Hei for safekeeping and draws his sword.
Meanwhile, A Ka Kin reaches the Zhao army's rear and decides to flank it with his cavalry. In his head he asks that Shin to hurry up, since they don't have much time left. Shin starts to keep up with Gaku Haku Kou's movements thanks to the change of weapon. In response Gaku Haku Kou abandons his mace and asks his soldier for his Moon Blade. The Zhao general claims and boast that this weapon complements his martial arts the best. The duel continues as Shin becomes more agile and fast on his feet. Suu Gen talk about how Shin needed to become stronger in order to wield the glaive and now he's creating his own style of martial arts through self-discipline. Bi Hei remembers the time when Shin trained with Hyou as he cheers on his general. The chapter ends with Shin destroying one of Gaku Haku Kou's pauldrons while injuring him and the Zhao Duke becoming enrage.
