Qi Song used the last remnants of mysterious substance to obtain "Skill."
He was then trapped within a "Time Loop" he had excavated himself, one created on July 16, 1945.
The time cycle within it lasted only a few minutes.
It was located at the Trinity Test Site in New Mexico, United States—the site of the world's first atomic bomb test.

That meant—

His body was constantly immersed in a nuclear explosion environment, which was also the source of the "radiation" within that oppressive aura.
Qi Song himself—
