The Son-in-Law's Sign-In: My Foolish Wife Spoils Me Rotten

Modern programmer Chen Yan unexpectedly transmigrates into the body of the "simple-minded live-in son-in-law" of the Su family, the richest family in Yunzhou, and awakens the Heaven's Chosen Comeback System. Daily sign-ins reward him with martial arts manuals, ingenious business techniques, and strategies for governing the realm. Facing contempt from the Su household, humiliation from his brother-in-law, and schemes from his romantic rival, he uses his "foolish boy" act as a cover and gradually reveals his talents through the System's missions. He resolves the Su family's business crisis, helps his foolish wife Su Zhaorong reclaim her stolen inheritance, and uses modern economics to revitalize Yunzhou's trade. In the end, the once-bullied son-in-law becomes a legendary figure who sways the imperial court, rising to the top hand in hand with the seemingly cold but warm-hearted Su Zhaorong.
