Siheyuan: I Strike It Rich Through Hard Work and Marry Chen Xueru

Su Fang transmigrates into a destitute boy fleeing famine to the capital. Orphaned, he goes to live with his maternal grandfather, only to inherit two old rooms and face the courtyard's collection of troublemakers. By chance, he activates the Work Hard to Grow Strong System, which improves his abilities even when he's cooking or sweeping. He masters the culinary arts and reaches the pinnacle of martial arts. He won't indulge ungrateful people or give in to moral blackmail. He goes from a down-and-out boy to a tough man the entire courtyard is afraid to provoke.
