Lu Chan, a longtime martial arts game player, discovered that she had transmigrated into the game. Now she could show off her skills. Wait a minute. Is this not my account? No? What is this? A cannon-fodder NPC who's about to die! This is the famously lovesick young lady who throws herself off a cliff for love! How did I become her System? No way. How am I supposed to save her? You can't reason with someone who's blinded by love! Forget it, I'll save her. Otherwise, what if she dies and I can't complete my mission? Lu Chan's thoughts on their first day together: Sis, please don't be lovesick this time. I'm begging you. Lu Chan's thoughts on their second day together: Huh? She doesn't seem lovesick. Lu Chan's thoughts on their Nth day together: Wait, why did her canon love interest suddenly die? The plot's changed so much. This is thrilling, and I love it. Lu Chan's thoughts on their N plus Nth day together: Something was definitely wrong with her death in the original plot! Who was behind it? Not long afterward, the young lady, now the leader of the martial arts world, hefted an unparalleled divine weapon. "I heard someone used to gossip behind my back and say there was something wrong with my head." Theme: Cherish life and friendship, and uphold the spirit of chivalry.
