Although Zhou Chun didn't know whether the environment of Black Mist Marsh could disrupt a Nascent Soul True Person, killing Wang Jun here would significantly increase his chances of escape.
Moreover, Black Mist Marsh was far enough from the Thunder Cliff Valley's mountain gate, granting him sufficient time to slay Wang Jun.
Now, Wang Jun's tactic of holding out for reinforcements played right into his hands.
Only to see him leisurely maneuver the Taibai Slice Flood Dragon Sword and the silver spear in a back-and-forth melee, then wield his Lifebound Dharma Treasure, the Myriad Transformations Golden Cauldron, to unleash golden sword rainbows toward Wang Jun's true form, and at times use the white Treasure Mirror obtained from Ice Hell Sect assassins to project white ice light at Wang Jun, forcing him to divide his attention to defend.
