This Is Spatial Energy?

When the frequency of his Internal Breath vibration reached the limit of what Chu Nan could control—6381 Hertz, he stopped continuing to adjust the frequency of his Internal Breath. While he divided a portion of his energy to maintain the high-frequency vibration of his Internal Breath, he let the other portion of his energy focus on sensing the strange energy.

At first, he only felt that strange energy through his Internal Breath and did not know how to contact and influence it.

After a while, he suddenly had a thought. He stretched out his left hand and stretched out his Internal Breath further, letting it enter the space further away from his body.

As expected, there were countless extremely weak and almost negligible unknown energies in the surrounding space that seemed to be attracted by his Internal Breath and gathered from all directions.
