Xu Qing bade farewell to King Lin, settling one concern in his heart.
King Lin had already agreed, before Lantern Festival, to descend the mountain and stay near Su Lianqing's Fragrant Plum Cottage, awaiting only the Great Elder of the Lotus Sect to make a move, before finishing off the old fellow.
Prior to Refining Internal, King Lin could not achieve Spirit and Body Integration, thus his Martial Arts Qi-Blood, in the eyes of a newly emerged Divine Soul, would be as conspicuous as a lamp in the night.
But now that King Lin has achieved Spirit and Body Integration, his Qi-Blood is subdued, to the point where even the temples on his head no longer bulge. He purposefully conceals himself; unless a Martial Arts Grandmaster comes close, it would be hard to discern his profound skill.
At best, from his physique, one could tell that he is a stronger man than the average person.
