Battle Through the Heavens Season 4

Xiao Yan's journey grows darker and more treacherous as he pushes deeper into the Black-Corner Region — a lawless land ruled by power and blood. With his beloved teacher Yao Lao's soul still trapped and weakened, Xiao Yan burns with a singular obsession: to gather the rare Heavenly Flames needed to revive him. But standing between Xiao Yan and his goal are ruthless sects, deadly rivals, and the shadowy reach of the Soul Palace — a terrifying organization that hunts and harvests the souls of powerful cultivators. As Xiao Yan forges new alliances, masters dangerous new techniques, and fights battles that push him to the very edge of death, he begins to uncover the full horrifying truth behind Yao Lao's capture and the dark forces that have been manipulating his fate all along. The stakes have never been higher — and only the strongest flame can pierce the deepest darkness.
