Let me block the tribulation? This Time, I'm the Dragon Lord

Thalia, a pure-blood ancient dragon, loses everything after failing the Ascension Trial. Her husband, Dragon Lord Drakon, seems devoted—until she discovers he sealed her power, sacrificed her for her foster sister Elara, and helped hide her parents' murder. After faking her death, Thalia returns a thousand years later as the strongest dragon alive, determined to take revenge and claim her destiny as the new Dragon Lord.
