In Qingyun City, in the Eastern Wasteland, the Zhang family's young Zhang Yanchen has had his spiritual root sealed, and everyone laughs at him as a good-for-nothing. Yet deep in his dantian lies the legacy of the ancient Heaven-Devouring Emperor: the Chaos Heaven-Devouring Art. He devours spiritual energy, medicinal power, true essence, blood essence, and strange flames, until he has devoured everything under heaven!
From family trials to sect tournaments, from the arena in the City of Heavenly Prodigies to the frozen wastes of the Northern Plains, he fights his way upward, carrying his burdens all the while. The debt of his clan's annihilation ten thousand years ago, a promise from the Keeper of the Lamps that was never fulfilled, a clan of Gatekeepers who have kept their watch for generation after generation, and the living man who endured thirty years in the Abandoned Ledger City... There are accounts in the heavens, and those that never get settled become abandoned debts anyone can come to collect.
After enduring the ninefold heavenly tribulation and ascending for seven days, he enters the second layer of heaven's counting house, where he sits across from a bookkeeper who has waited three thousand years, and they pore over two ledgers through the night. There are eleven layers above, each heavier than the last. Beyond the ninth layer waits the Abyssal Lord, who oversees collection.
Zhang Yanchen says, “I don't fear a heavy debt. I fear no one coming to settle it.”
A good-for-nothing's rise, devouring the Myriad Daos, ascending one heaven at a time. This time, he will settle every account in the heavens, one by one, once and for all!
