Ye Lin plucked a hair and held it before his eyes for a closer look.
Its cross section was no longer round. It formed a hexagonal prism, each face as sharp as a blade.
He gave his head a gentle shake. The hair traced an arc through the air, cutting a fine fissure in the void wherever it passed.

"But I'm already more than satisfied."
Ye Lin thought this to himself.
The hair was not only sharp but extraordinarily tough.
He pinched both ends of a strand between his fingers and pulled hard.
The hair stretched to nearly twice its length but did not break.
When he let go, it snapped back into shape without the slightest deformation.
