According to common logic, a thin silver needle pricking someone's face shouldn't cause such intense pain.
But now Howard's piercing screams are as if he's experiencing bone-crushing agony.
The reason for Howard's screams is nothing else but Lu Yu's silver needle piercing his trigeminal nerve!
The trigeminal nerve lies deep within the facial structure, interconnected with multiple nerve fibers in the head, and when struck, it triggers waves of excruciating pain.
The pain is so intense that ordinary people can scarcely endure it!
Because of this, the trigeminal nerve is generally protected by bone, never to be disturbed.
However, Lu Yu is no ordinary man; his silver needle precisely targets the trigeminal nerve's endpoint hidden beneath facial muscles.
The trigeminal nerve is extremely sensitive; when stimulated, it instantly releases intense pain sensations.
