Lin Tian hadn't expected that the invasion of the pink aura would trigger the deepest Taiyin Xuan Qi within his body, which effortlessly extinguished the pink aura.
Taiyin Xuan Qi had appeared before; he remembered the first time he battled the Heavenly Master Girl. When he was scorched by her Demon Slaying Golden Flames, Taiyin Xuan Qi had also emerged.
Another time was at the Fanyin Temple in Zhonghai City when he was holding a golden sword and was burned by the sword's flames, which also triggered the Taiyin Xuan Qi.
Previously, as a regular human being, not knowing about the existence of Taiyin Xuan Qi was excusable. Now, having become a zombie and gained x-ray vision, he was still unable to pinpoint where the Taiyin Xuan Qi was hidden. His Dantian seemed like an infinitely vast void, forever elusive.
