With a thought, the soul left the body through the back of his head. At this moment, it wasn't yin mist, but it had gathered into a ball—like a slowly flowing circular whirlpool.
When it left the room, a glow shone around it. Even with the blazing sun in the sky, he didn't fear anything.
During the return to the sun realm, even during the 15th of the month when the moon was high in the sky, he could wander the night with his soul as he wished. Even in the morning or during the evening when the daylight was weaker, he could also leave the body.
Within that yin soul, some yang nature had been birthed. Now, he could slowly resist the burn of the sun.
