"For a 600kg weapon, a typical adept would have to be at least level-five of the gathered qi to be able to use it with ease. Furthermore, even for a adept of level-five of the gathered qi, he could only use it for a short duration. To be able to use it at ease, one would need at least level-seven of the gathered qi." After Fu left, Zhou Donghuang sat on the bed in the inn, muttering to himself as he stared at the black iron spear leaning against the wall. "At my current strength, to be able to use this heavy black iron spear at ease for even a short time would only be possible with perfect execution of 'Qi-Stacking.'"
Qi-Stacking was a level-one martial art technique different from the typical level one techniques. For typical level-one techniques, Zhou Donghuang simply could not execute them with his current qi. Even if he managed to execute it, the power would only rival level two martial arts, and his internal qi would be completely depleted with just one use.
