This is a basic safety technique for specialized climbing and fixing the body position. As a military combat exemplar adept in climbing skills, the chubby guy naturally excels in climbing proficiency. However, such a smooth exterior wall is not only hard to climb but even harder to move downwards. To fix his body on such a smooth surface, the chubby guy relies entirely on the core strength of his finger bones, managing to bear the load in a gap of merely two centimeters, his lower limbs having no support point at all.
Chubby slowly lowers one arm, successively gripping another crevice a meter away, like a spider clinging to the wall, continuously moving his palm and fingers, causing the glass curtain wall to emit a series of crackling collision sounds.
