I finally managed to kill the demon lord.

She had always thought that he was a devil in human flesh. She feared him and hated him for the sins he committed but after seeing how much he changed to be a better person for her, it took her a great amount of courage to forgive him since by the time she found out the truth about him, she had already loved him. From being the worst husband and father to the best husband and father one can ever have. Lu Yifeng was given a second chance to correct every wrong deed he did. He was the man who destroyed their family and it took death to make him realize his wrongdoings. . . . . "Meilin, come here." She turned to her husband and smiled, "Mr. Lu, we are at work, didn't we already agreed to behave while we're here?" "I want to have an affair with my secretary." Lu Yifeng said calmly. "Can I?" Xia Meilin narrowed her eyes, "No." He stood up and walked toward her which made Xia Meilin take a few steps backward away from him when she saw the dangerous look on Lu Yifeng's eyes. She stopped when she felt the cold wall against her back. Lu Yifeng ended up cornering her. "I'm the President of this company, I do whatever I want to do, including having an affair with my secretary." Xia Meilin refused to back down that's why she ended up glaring at him. "Do you want to get beat up by your wife?" The side of his lips curled up into a smirk, "Will she now?" He cupped her chin and bowed his head to place a soft kiss on her lips. "Then stop acting as my secretary. You're my wife, it's your job to watch over your husband. If you want to have a salary, then I can give you all my money." A faint blush appeared on Xia Meilin's cheeks after she has been kissed by him. She pouted and turned her head away, "I just want to try how it feels to work as your secretary."

When a person dies, they either die light as a feather (aka unimportant) or heavy as Mt. Tai (aka very important).
