Lu Jiahe, a doctor of agricultural sciences, has a motto in life: "Knowledge is power, technology changes life." When she opened her eyes, she became a small peasant girl on the road to escape from the desert in ancient times. Her family was bare, her face was sallow and her skin was thin. The only asset in her hand was a broken bowl with its mouth opened. Good news: She traveled through time. Bad news: If you don't wear it properly, you will start in the hell-difficulty famine mode. Goldfinger? System? Portable space? Sorry, not at all. Lu Jiahe wiped his face, looked at the land that was so barren that rabbits didn't poop, and a group of villagers who were so hungry that they were chewing tree bark, and gritted his teeth: Without the golden finger, my brain would be the most powerful cheat! While others prayed to God, she dug soil and tested the pH; while others used child urine to water vegetables, she made plant ash and compost; while others had three hundred kilograms of land per acre, she used intercropping and grafting to improve it, and the yield per mu started at eight hundred kilograms! Villager A: "Oh my gosh, the girl from the Lu family got some guidance from a fairy, right? Her wheat is taller than a human being!" Villager B: "What kind of fairy? I saw her burying fish bones in the ground and talking about 'nitrogen, phosphorus and potassium'. I'm afraid she's not a little witch!" A certain general who passed by this place and had a private interview incognito was rejected: "...'Witch'? Write down her 'witchcraft' for me, the army will depend on it!" Lu Jiahe just wanted to quietly engage in scientific research and lead the whole village out of poverty and become rich, but accidentally, he brought the entire ancient agricultural technology to a new level. From a small peasant girl to the founder of the world's granary, from the questioned "witch" to the "god of agriculture" written in agricultural books. Lu Jiahe: I am really just an ordinary farmer.
