Venomous Echo

The S-rank chamber hummed faintly as Aziz lowered himself into yet another pushup, his muscles trembling under the weight of the enhanced gravity. 

Sweat dripped from his forehead, pooling on the pristine floor beneath him. 

Every breath felt like dragging air through wet cement, the pressure bearing down on his chest and making it harder to fill his lungs. His arms burned with lactic acid, his entire body straining under the relentless force he had demanded from the chamber.

"Increase gravity pull by two levels," Aziz muttered between labored breaths.

The walls responded with a soft hum of acknowledgment, and a surge of energy rippled through the room. 

The air grew heavier, denser, pressing down on him like the weight of a mountain. His elbows buckled slightly before he locked them again, his teeth gritting as his body adjusted. 

This was exactly what he needed.
