Grinding Proficiency in Spirit Cage

Ye Qiu died from working overtime in an office in the 20th century. When he opened his eyes again, he found himself in the apocalypse of Spirit Cage.

Under a blood-red sky, the howls of the devourers were right nearby.

While fleeing for his life, he activated a proficiency panel and discovered that even basic breathing techniques could be upgraded.

Just as the claws of a pack of snake-dogs tore into his back, an armored vehicle came roaring up.

Through her binoculars, Bai Yue Kui's gaze pierced the dust and smoke, settling on the bedraggled stranger.
