The air wall seemed to be welded to the space, with extremely low friction. The White Horse Tombstone exhaled sharply backward, and the whole person slid smoothly forward, passing over Wan Ling's head.
The peak speed of a human head's horizontal rotation (axial rotation) is 1432°/s and the coronal plane (lateral flexion) is 722°/s. Wan Ling's head followed the sliding trajectory of the tombstone, the corner of her eye barely catching the afterimage of the latter,
Spurt!
The White Horse Tombstone's limbs were all severed in mid-air, the stumps smooth as a mirror, and thick black blood gushed out. Only a small section of the left arm remained.
She was expressionless, seemingly devoid of pain. At the moment she exited the edge of the air wall, she lowered her center of gravity, using the protruding half of the left arm's bone,
to hook onto the vertical edge of the wall, swinging her entire body forward, once again passing over Wan Ling's head.
