Jiang Muyun knelt on the snowy night and begged the operating room to open. Her fingertips were frozen and cracked, but she still clutched the critical illness notice - Lu Shubai, her ex-husband, had liver failure and only had 72 hours left. Ten years of marriage were shattered by a misunderstanding, but he silently donated half of her liver when she was in the most embarrassing situation. Now that he was unconscious, no one in the hospital dared to accept this "deadly technique", but she did. When the monitor's alarm tore through the cold night, she cut her wrist artery and poured plasma into his circulatory system: "Lu Shubai, if you dare to die, I will carve your name into my bone marrow. You will never escape for the rest of your life."
