Reborn as a Cannon-Fodder Farm Girl? I Read Minds, Farm, and Become Queen

Agriculture PhD Su Maimai wakes up as a peasant girl destined to be cannon fodder, doomed to die before chapter three of an old-school tragic romance. Her parents are honest, her younger siblings are still little, and the whole family is destined to be stepping-stones on the protagonists' road to success, with a miserable ending awaiting them all. From the start, vicious relatives show up to force her into marriage, planning to sell her off as the second wife of a fifty-year-old landlord. Su Maimai gives a cold laugh, then unexpectedly discovers that she can hear her family's thoughts! [Oh no, Auntie is trying to force my sister to marry again. I need to grab a weapon and take her down!] [Dad, get it together! Bring out the same spirit you had when you went up the mountain to fight a tiger, and beat them all out of here!] Hearing her younger siblings' innocent yet fierce thoughts, Su Maimai feels a warm glow inside. No worries. With a golden finger, what is there to fear? She has mind-reading in one hand and modern agricultural know-how in the other, and leads her family to quietly build their fortune. Short on grain? No problem. She has high-yield seeds that will astonish everyone with their harvest. No money? No problem. She grows greenhouse vegetables, so even the capital's elite can eat fresh produce in winter. Troublesome relatives come looking for a fight? After the whole family hears her thoughts, every one of them turns into a brilliant actor, helping her put on a show and dish out face-slapping, keeping the troublemakers dancing in the palm of their hands. As life gets better and better, Su Maimai only wants to be a low-key rich woman. But at some point, the regent, rumored to be cold-blooded and ruthless, starts looking at her in a rather peculiar way. [Why is she so cute? I want to pinch her.] [She didn't talk to me again today. I'm upset.] [When can I bring her home as my wife?] Su Mai Maimai, who only wants to focus on her career: ??? Your Highness, your character setting is falling apart!
