The Son-in-Law Hero Smirks

Blurb: There was a face-slapping power fantasy novel about a dragon king's son-in-law. The son-in-law worked like a beast for his father-in-law's family, while his wife, who looked down on him, cheated on him four, five, six, even seven times. After becoming the ultimate cuckold, the son-in-law tried to put up with it. Then his wife kicked him to the curb, and he finally snapped, curling his lip into a smirk. His ex-wife's family: Dead! Cheng Yin found it so satisfying that he applauded. Then, in the blink of an eye, a brick sent him into the son-in-law's home, where he became the doomed husband who was about to be face-slapped along with his entire family, all of them destined to die in the street. The son-in-law was devastatingly handsome, so handsome that just looking at him was unforgettable. If someone like him started smirking... Cheng Yin: Wait, there's still time to save him! I can't let him get the chance to smirk! As soon as he got home, he blocked the original owner's four, five, six, and seven. First, he signed up for New X... Oriental Cooking School, then he started frequenting foot massage parlors, bathhouses, blind masseurs, and street fortune-tellers to learn their trades. Before long, he returned, fully trained. The son-in-law dragged his exhausted body home, ready to get back to work. But when he opened the door, he found the place completely transformed. His partner in name alone had a pair of long, hot legs and welcomed him enthusiastically. "Honey, you must be exhausted from laying bricks! Come sit down. I'll give your feet a massage." The son-in-law was flattered and tested the waters. "Th-then, let me try it." (The massage felt so good that his head practically smoked.) Then the newly hired housekeeper took over all the chores he'd been doing. Every morning and evening, he heard: "Honey, look at you, all sweaty. Let me wash your hair and relax your scalp." (The shampoo felt so good that his head practically smoked.) "Honey, let me tell your fortune. Sure, you're laying bricks now, but your chart says you're a hidden dragon in the abyss. One day, you'll soar through the heavens!" (The praise felt so good that his head practically smoked.) "Honey, your belt's worn out. How about this new one I bought? Let me take yours off and put this one on!" (The belt change felt so good that his head practically smoked.) The three-year agreement was finally up. The son-in-law, whose lips had been teased into a permanent pout, was fretting over how to tell his wife that he was actually from a wealthy family. The son-in-law held a bouquet of roses, nervous and uncertain. As he reached the door, he heard the wife who treated him like a treasure bragging to her childhood friend. "I knew all along he was rich. I only teased him so he wouldn't get revenge on me." "I heard he's straight. He wouldn't just turn gay, and he was only playing around with me. Besides, I heard he bought flowers today to confess to his first love!" He turned around and saw the son-in-law standing there, holding roses, his face ashen. Cheng Yin gave an awkward laugh. "Would you believe me if I said I had too much to drink?" The son-in-law: "Hah." You're finished. Reading guide: - Maybe a ridiculous comedy. - A shou who sells his skills to change his fate, striving to play the virtuous wife and little swindler x a powerful, fake-straight gong who smirks and gets teased into a permanent pout, the son-in-law [The title and blurb are provisional.
