After Returning Home from the Imperial Exams, My Son Becomes the Academy's Favorite

[Imperial exams + court politics + farming + alternate history + food] The overachiever Liu Cheng'an transmigrated one day into the body of an eight-year-old boy in Liu Family Village! There wasn't a grain of rice to eat, and you could see the stars through the roof. A disastrous start, but at least his father was a licentiate! After working himself to the bone in his previous life, all he wanted now was to reclaim his well-earned lazy days! But his licentiate father kept failing the exams and had a serious aversion to studying. The whole family was about to starve. To protect his peaceful life, he had no choice but to step in himself! No money for the exams? No problem. He took over the academy cafeteria and started writing books to bring in one batch of exam funds after another for his father. His father hated studying? No problem. Liu Cheng'an brought out collections of past exam essays and three years of practice tests and five years of mock exams, driving the whole academy into a frenzy of studying alongside his dad! He had only meant to get his father through the exams, but somehow became the academy's favorite. After ten years of study, his father finally passed. But when he returned to his hometown, he was stunned: former classmates chased after him, calling him “godfather,” while even his sworn rivals fawned over him. Liu Cheng'an was very pleased to see his father pass with flying colors. What? His father was being ostracized by his colleagues at court? Looks like they were still too idle and had never experienced a 996 work schedule! The officials at court trembled, all hoping Chancellor Liu would speak to the emperor less often. Failing that, they would gladly retire a day early if they could! Years later, Liu Cheng'an stared blankly at the umbrella presented by the grateful people. Wait, wasn't I only trying to lie flat in the first place?
