It Was You Who Refused to Marry Me at the Beginning. Why Are You Crying When I Become the Emperor of Heaven?

"Sister, I regret it. Can you return my brother-in-law to me?" When Su Qingyan saw that her fiancé Qin Changye had trained her sister who could not practice cultivation into the first empress of the three realms, she regretted it. Qin Changye was originally a reborn emperor, but he stayed in the Su family for ten years for a marriage contract. His fiancée disliked him for being blind, so he regretted the marriage and asked his sister to marry him instead. But she didn't know that on the day of the wedding, the emperor's soldiers returned to their positions. The heaven-refining furnace refines the three realms into golden elixir, and the immortal-burying sword kills immortals like ants. Back then, you would rather die than get married. Now that I have become the Great Emperor, why are you crying? This book is also called "Burial of the Immortal Sword Emperor"
