The nine realms are in ruins, and the dark tide is spreading all over the world.
Yuanshi's heart mirror suddenly shattered, and nine fragments scattered around the world. The regret and unwillingness in people's hearts turned into a dark tide of catastrophe, and nightmares and deformed monsters swept across the Wanxiang Continent.
Yin Mo, a young man from Jincheng, received the Lingying Seal passed down from generation to generation by the Yin family at the age of sixteen, and embarked on a journey across the nine realms to find the fragments.
The nine fragments do not correspond to peerless magic weapons, but to nine heart locks that trap people's hearts: Qingmu's thousand-year wait, Yinshuang's separation of life and death, Chiyan's old regrets, Houtu's obsession with burdens, Lei Xiao's past sins, Windyin Valley's unspoken farewell, Tianqiong Ridge's ego, Canghai's sinking despair, and the self-confrontation in the Nameless Realm.
Along with everyone along the way: Su Nianwei who is waiting for reincarnation, Liu Qingshuang who bears the pain of her family, Shang Yinyue who uses poetry as a mantra, chivalrous ranger Shen Jinghong, and Zen monk Fan Chan who sees through illusions. They fight against the deformation of wild beasts, and face the past that they cannot let go of.
The gray-robed Dark Lord is not an alien demon, but the aggregation of the obsessions of thousands of sentient beings, reflected in the mirror of Yuanshi's heart.
In the wilderness of Guixu, a life-and-death battle took place. Everyone defended the defense line with their flesh and blood. Yin Mo completed the unity of heart and mirror, and the catastrophe of the dark tide was temporarily contained.
But victory is not the end. The "Reincarnation Lock" inscription left over from the ancient times appears in the world. The mysterious forces in the dark are collecting the lost ancient secrets everywhere. The dark master uses the ancient fragments to escape without a trace. The spring breeze of the world has revived, but the deeper mystery has only just surfaced.
This is a fantasy that reconciles inwardly and protects outwardly.
