At the meridian-testing ceremony, Ye Chen is declared to have a useless meridian and suffers every kind of humiliation.
That night, disaster strikes his clan. As his father lies dying, he whispers in Ye Chen's ear, "Chen, your meridian isn't useless... You possess the last Chaos Heavenly Meridian in this world."
A heartbeat from deep underground resonates with him, and a cold voice sounds in his mind: [Chaos Heart System activated. Main quest: Gather the Ten Imperial Artifacts and reclaim the throne of the Imperial Venerable.]
From then on, burdened with the System, he sets out to find the lost Imperial Artifacts.
He meets a girl whose memories are frozen. She is the reincarnation of the Mystic Ice Empress.
He meets the elder sister whose fate is bound to his, yet the core of a Heavenly Demon is sealed within her.
Each time he obtains an Imperial Artifact, he unlocks a buried truth: the sacrifices of the Ten Emperors of antiquity were not made to seal away the Heavenly Demon, but to... bring him into being.
Then the System's final message cuts to the bone: [On the day you gather the Ten Emperors' legacies, you must refine Chaos with the blood of your closest kin and dearest loved ones.]
When his sister plunges a dagger into his chest, smiling through her tears, he finally understands: from the very first step, this path to becoming the Imperial Venerable of the Ten Directions has been written with farewells.
