Conquering the World, Starting with the Imperial Exams

[Reincarnated in the Womb + Farming + Imperial Exams + Fleeing Famine + Warfare + Age of Exploration] The slow-paced daily life of a farmer's son in ancient times! Zhao An gets a second chance at life and transmigrates to the bitterly cold frontier of the Great Zhou Dynasty. Unfortunately, his family is poor. He has four older sisters and a twin sister, and he is the only boy his parents have hoped for over the past five years. His parents favor boys over girls, and all five of his sisters are capable. He thought he was in for a story about sisters who would do anything for their little brother, but it ended up being a story about a brother who would do anything for his sisters! Being the only male in the family is a huge burden. At first, all he wanted was to pass the imperial exams and live in peace. Who could have guessed that this crumbling empire would be so unstable? The Sushen cavalry are poised to invade, bandits are rampant, and years of famine have come with the Little Ice Age. Zhao Fan hasn't even passed the provincial exam, and he's already on the verge of dying. With famine and war all around, he has no choice but to take his family into survival mode and get swept into the whirlpool of the times. Luckily, he has a Family Development System: it gives him money based on the number of people in his family and lets him draw talents. From the start, he earns ten coins a day. Save enough, and he can draw a talent!
