Bai Lingxi, who took the form of the bones of the ancient world, was once the all-powerful Holy Bone Master of Wan Yao Ridge, commanding hundreds of millions of bone cultivators. However, because of his great achievements, the master was suppressed by the Heavenly Dao and Lingshan together in Baihu Ridge for eternity. On the day when the Bible-seeking team passed by, the seal was loosened. She broke the seal and woke up. She was met by the bone cultivators sent by the Black Bone Elders to disguise themselves and provoke the Bible-seeking team. Seeing the tragic death of his kindred, Bai Lingxi, furious, immediately fought with Sun Wukong, shaking the three realms with terrifying power that shocked the gods.
In order to protect the origin of the White Bones, find out the truth about the betrayal, and rescue the remnant souls of her kind who were held hostage by Lingshan, she was forced to agree to Guanyin's conditions and join the Bible-seeking team full of hostility, becoming the most dangerous variable in the Tiandao chess game. She kills decisively, does not flatter Buddha or tame heaven, and tears away the hypocrisy of Buddhism, but always adheres to the bottom line of cultivating bones and not harming innocent people. The rebellious Wukong, the transparent and sensible Tang Seng, the honest and enthusiastic Bajie, and the silent and reliable Sha Seng—this group of "others" went from tit-for-tat to protecting each other in life and death, gradually forming a bond in the frozen hearts.
On the way westward, she uncovered the series of traps set by the Black Bone Elder, defeated the deadly conspiracy of the ancient Buddha of Burning Deng, and also revealed the secret past of her battle with the ancient gods. When Bai Lingxi gathered all the holy bones and broke through the shackles of cultivation, she set foot on the top of the Lingshan Mountain, shattered the hypocritical mask with thunder, and forced Heaven to recognize the orthodoxy of bone cultivation. In the end, she transformed into a gentle but powerful guardian of the three realms, and the scripture collection team also broke free from the shackles of fate, each achieved perfection, and lived in peace together.
