Please, Master, Go Down the Mountain and Wreak Havoc on Your Seventh Senior Sister

[An overpowered wish-fulfillment story + absolutely no saintly do-gooding + decisive and ruthless action + adored by a sister squad + extremely calculating] “Disciple, the pure-yang heavenly flame inside you is almost beyond control. Get down the mountain, quick, and go cause trouble for your seven gorgeous senior sisters!” Su Chen was driven from his family home in a massacre and spent ten years keeping a low profile on the mountain. Now his shameless master kicks him down the mountain. He just wants to quietly call off an engagement and look into his enemies. But his fiancée humiliates him at every turn and even threatens to break his legs? Su Chen stops pretending! He tears up the marriage contract, and his icy CEO eldest senior sister arrives in a hundred Rolls-Royces to fiercely defend him: “Whoever lays a hand on my junior brother, I'll wipe out their entire clan!” His second senior sister, the king of assassins: “Junior brother, a hundred thousand assassins from the Heavenly Net are ready. Point to someone, and I'll kill them!” His third senior sister, the peerless God of War: “Junior brother, a hundred thousand troops are assembled. Which family should we wipe out?” Faced with a villain's wild boasts: “Boy, I'm a master of the Transformation Realm! I have powerful people in the capital backing me!” Su Chen slaps him into a cloud of blood and looks innocently puzzled. “What master? A cultivator beating up martial artists is just a higher-dimensional smackdown, isn't it?”
