She is the fourth child in her family, with two older brothers and a younger brother. The whole family follows her lead, because every member of the Ma family has been orphaned. To survive, she, a modern woman with a university degree in agricultural cultivation who has transmigrated into this world, has to become strong. Wait, who is this Young Master Zhao claiming to be her distant cousin? All she did was rescue an amnesiac man while gathering herbs in the mountains, and now he's insisting they have some kind of connection. He stays with them to recover, then refuses to leave even after he's healed, joining her brothers in serving at her beck and call. Hunting, plowing fields and growing rice, gathering herbs, selling snacks, even raiding a hornet's nest, he does it all. This mysterious cousin is quite the handful. He won't eat leftovers, use old bedding, or drink rough tea, and he expects people to wait on him. Cousin, at least pay up! Who could have guessed that he would suddenly leave tens of thousands of taels behind and disappear without saying goodbye? Half a year later, his true identity as "Cousin" is exposed, and he firmly insists on marrying her. When she refuses, he threatens to use his position for personal gain and go into business with her medicinal herb fields. The medicinal herbs she grows can heal great generals and help ordinary people. When the emperor learns of her deeds, he confers on her the title of Divine Medicine Saintess. Now her doorstep is trampled flat by people seeking a marriage alliance. Fine! Whether he's doing business with her or marrying her, the old rule stands: she calls the shots!
