Under the night sky.
A cool breeze brushed across the rooftop, gently swaying the clothes on the clothesline, the chirping of crickets echoing intermittently.
Lu Yuan stood near a concrete pile, assumed a stance, and slowly threw a punch towards it.
This punch was incredibly slow.
As he punched, large beads of sweat visibly formed on Lu Yuan's forehead and cheeks.
He gritted his teeth tightly; he looked like he was struggling immensely.
His eyes remained fixated on his right hand as it threw the punch.
His right hand was a whole size thicker than usual!
The muscles on his arm churned like waves; blue veins, usually hidden beneath the skin, bulged out, swelling like earthworms.
Lu Yuan felt as if the muscles in his right arm were rapidly twisting together like strands of a hemp rope.
Contracting, expanding, exploding...
POP!
A crisp sound burst from his punching right hand.
The sound was like an overstretched bowstring suddenly snapping.
