Consequently, as the host's inner qi continuously drained away, his cultivation realm would inevitably plummet until he was reduced to an ordinary mortal. Yet, the Qi Gu—deprived of the stimulation of inner qi—would simply relapse into a state of suspended animation, posing no threat whatsoever to the host's life.
This precisely explained why, when Chen Feiyu had been uncertain as to whom the Long family intended to revive, he had slipped the Qi Gu into the Soul Returning Pill. It guaranteed that the target's life would be spared while effectively neutralizing any major threat they might pose to him.
Thus, the Qi Gu was a parasite specifically designed to target martial arts experts. The stronger the opponent, the more domineering the power of the Qi Gu would be. By contrast, had he used some other lethal poison in the Soul Returning Pill, it might not have posed any threat to the Xiantian Realm Long Jingyun at all.
