Lin Ye, an outer disciple of the Qingming Sect, appears to have a damaged spiritual root and to make little progress in his cultivation. In truth, he has a hidden connection to the "Qingming Sword Pendant." His parents died in a secret realm while searching for a treasure that could restore his spiritual root. After his background is exposed, the Supreme Elder Xuanji Zi offers him guidance: he must grow stronger before seeking the Qingming Sword Pendant his parents left behind. For now, he lies low among the outer disciples as danger begins to emerge.
The seal at the Abyss of Ten Thousand Evils is weakening, and ancient evil energy is leaking out. The Shadow Evil Sect takes advantage of the chaos, plotting to unseal the demon beasts and overturn the world. Lin Ye, a descendant of the Star Slayers, unexpectedly inherits the Spirit-Guiding Jade and sets out to defend the righteous path, bearing the power of the Three Saints: the Star Pivot, Moon Soul, and Sun Wheel.
He finds the Star Pivot Crystal Source in the snowy wastes, narrowly claims the ancient Moon Soul Jade in the Southern Border, and obtains the Sun Wheel's flame seed in the Southern Bright Blazing Fire Cave. The Spirit-Guiding Jade gradually awakens its divine power of purification. Along the way, he meets Lin Xiaowan, heir to Hundred Herbs Valley, and Lu Qing, a disciple of the Qingming Sect. Together, the three form a team to slay evil. From breaking the Blackwater Cult's Water Evil Formation in the waterways of Jiangnan, to destroying the Ten Thousand Poisons Pill of the Poison Shadow Cult in the Miao borderlands; from smashing the Soul-Eating Banner of the Bone Wind Cult in a northern desert bone mound, to defeating the sea demon priest's Wave-Summoning Pearl on Return-to-Ruin Island in the East Sea, they travel across the Nine Provinces and purge evil spirits wherever they find them.
When the Shadow Evil Sect's leader offers a blood moon sacrifice to destroy the seal, Lin Ye gathers the power of the Three Saints and joins forces with the Alliance of the Righteous Path for a final showdown in the northern lands. His star-marked sword cleaves the darkness, and the Spirit-Guiding Jade bathes the earth in light. The evil spirits are scattered, and the seal is restored. But their mission to protect the world will never end. As long as evil takes root, they will appear wherever light is needed, safeguarding peace under the name of Qingming.
