Jian Huan found herself transported into a xianxia novel as the fiancee of the main antagonist.Feeling her empty wallet, she recalled the pitiful fate of the original owner of the body who stubbornly refused to annul the marriage. Without hesitation, she took the marriage contract and went to the antagonist for a friendly negotiation.At this moment, Shen Jizhi, the future scourge of the cultivation world, was still a righteous disciple. He silently looked at the marriage contract with a cold expression, asking, “How can I get you to annul this marriage?”“One hundred thousand spirit stones,” Jian Huan held up ten fingers, “as long as you pay one hundred thousand spirit stones, our marriage will be void.”Shen Jizhi fell into silence for a moment. “Is there nothing else you want me to do?”Jian Huan shook her head. “None.”Shen Jizhi asked sternly, “You will only accept this condition?”Without hesitation, Jian Huan replied, “Yes.”Shen Jizhi’s tone turned harsh. “Then there’s no annulment.”Jian Huan was confused. “?”Shen Jizhi looked at her and said, “I won’t annul the marriage. We can get married whenever you want.”He bid farewell. “I have other matters to attend to. Goodbye.”Jian Huan exclaimed, “???”
