Northern Dark Ice Soul Physique

Fighting Lord Sky Crane on Qing Mao mountain, Bai Ning Bing self-detonates both arms to trap him in a spreading glacier, then begins freezing to death himself as his consciousness fades. Fang Yuan revives him with the Yin half of Yin Yang Rotation Gu, a rank four healing Gu that brings the dead back to life at a cost: the Gu Master’s aptitude drops by ten percent, and turning yang into yin also turns a male body female. Bai Ning Bing’s hundred percent aptitude falls to ninety, matching Fang Yuan’s own and hiding the Northern Dark Ice Soul Physique, and she emerges from the ice as a woman. ^{ch. 199} Fang Yuan keeps the paired Yang Gu, which can reverse the change, as leverage over her.

Hearing the report, Shang Yan Fei guesses the same destruction was brought on by a holder of the physique, matching how the site’s traces already read to unnamed observers; the aptitude’s existence is more or less known among the Gu Master world’s higher-ups even where the holder is not. ^{ch. 267}

As Bai Ning Bing keeps cultivating, her aptitude creeps back toward a hundred percent, and she deliberately delays advancing past rank three to slow its return rather than let the physique resurface. ^{ch. 275} The aptitude reaches ninety-three percent and continues rising even as she tries to hold it back, the ten extreme curse showing its effect regardless of her effort. Fang Yuan notes the two of them share a similar burden: Spring Autumn Cicada’s growing pressure on his own aperture against Bai Ning Bing’s physique. ^{ch. 301 ch. 304}

Bai Ning Bing later becomes a rank six dragonman Gu Immortal and takes ownership of Bai Xiang grotto-heaven along with Bai Xiang’s true inheritance. ^{ch. 1249} The physique complements that inheritance, multiplying its effect, and gives her battle strength that reaches rank seven even as a rank six. ^{ch. 1384 ch. 1395}

Northern Dark Ice Soul Physique is the best physique for cultivating the ice and snow path. As with Hei Lou Lan’s Great Strength True Martial Physique, Bai Ning Bing’s dao marks stand above those of most rank six Gu Immortals in the same condition. ^{ch. 1258}
