A Muslim man named Sha excelled in the powerful art of the Iron Shirt, his fingers honed like blades, capable of severing an ox's head with a single palm strike, and piercing the belly of an ox with a mere pointed finger.
Sha once performed an incredible feat at the Qiu manor. He suspended a wooden plank in mid-air, allowing two strong men to swing it out with all their might. Sha stripped off his upper garment, exposing his abdomen. Soon, the plank swung back toward him. With a solid thud, it struck his belly. Sha inhaled sharply; his abdomen swelled, his internal energy rebounding, and with a sharp crack, the wooden plank shattered into dust.
Sha then produced his yang organ, laid it flat upon a stone, and struck it forcefully with a massive iron hammer. The yang organ remained completely unharmed.
