He didn't barge in recklessly, but steadied his mind and descended into the hall below. The moment he landed, he abruptly turned his head, looking into the nearest hallway door. Inside that door stood a monk who appeared ghost-like, silent and still.
The aura on this monk's body was entirely gone, no signs of life nor death, even his presence was concealed. Had Han Yi not descended from above, he never would have detected a monk standing within the doorway.
His heart was vigilant, but he didn't strike first. Instead, he carefully observed the standing monk, who despite having no aura, still had light in his eyes. It was solid and unchanging, as if the person, along with that gaze, were frozen in a particular moment.
This was a youthful monk, and because there was no aura on him, Han Yi couldn't determine his realm immediately, but judging by his appearance, he seemed quite young and absolutely could not be an Immortal. With this thought, Han Yi's tensed heart slightly relaxed.
