Luo Yan saw Zhou Gu, immediately turned away from Cui Yanjin, and rushed toward him.
Before he reached Zhou Gu, he was intercepted by Zhang Yun and his men, determined to achieve the enfeoffment promised by Su Rong in words; if he killed the Empress of Dawei, it would be the major accomplishment of this battle.
Zhang Yun's martial arts, if faced head-on, were not necessarily a match for Luo Yan, but his greatest strength lay not in his martial arts prowess but in his sharp mind bordering on the cunning, which is why, shortly after leaving the central military tent, he had already devised a plan with the Hidden Guard to kill Luo Yan.
Thus, when Luo Yan broke free from Cui Yanjin and charged forward, he fell directly into Zhang Yun's trap.
The Hidden Guard, each having consumed a poison-avoidance pill, formed the Seven Kill Array, trapping Luo Yan in the center, with Zhang Yun waiting for him at the heart of the formation.
