Perception Expansion

On the morning of the thirteenth day, the wind on the platform carried a faint scent of dust, as though it had blown in from somewhere farther away. As Lin Chen practiced breathing at the eastern edge, he sensed the wind direction shift three times before settling at a new angle. It remained there longer than usual, as if the airflow had encountered some obstacle in the distance and was seeking a new path. He adjusted his breathing rhythm and felt the airflow within his body align with the wind direction, as though the two had established a stable synchronization through long training.

As he walked along the narrow path toward the stone door, he noticed that the moss on the walls was a deeper shade than it had been a few days ago, as though it had absorbed more moisture. The stone door was still slightly ajar. When he pushed it open and slipped inside, the circulating airflow within was moving faster than usual. He stopped at the center of the chamber without deliberately adjusting his stance, simply standing there as he felt the airflow pass over his body with greater intensity. After standing there for a while, he sensed the synchronization between the airflow inside him and the air outside growing tighter, as though they were establishing harmony across a broader range.

He felt the airflow's swirling range shrinking, as though it were concentrating inward from around his body. Once it narrowed to a certain extent, his body automatically adjusted his stance, his center of gravity shifting slightly back as though it had found a more effortless position. He remained where he was and felt the movement of that layer of air becoming finer and denser, like coarse sand turning into a thin stream. He did not move,
