Reborn as a Virtuous Crown Prince, I Beg to Be Exiled from the Start

[A Low-Key System + Historical What-If + Farming and Trade + Struggle for the Crown Prince's Succession] Lin Bufan transmigrates and becomes the virtuous crown prince of the Great Xia Empire. He should have been destined for the throne and a glorious reign, but then his personality suddenly changes... and he becomes the greatest wastrel in the land. His position as crown prince is at risk, and he is about to be exiled to Lingnan. It is all because his older sister in the modern world has only six months left to live, and he happens to be bound to an ancient farming System. If he can build a fief rated “Richer Than the World” within six months, he can save her life. But after enduring countless hardships and finally saving his sister, he prepares to lie flat in his fief, only to discover that more and more people at court want to be demoted and sent to Lingnan. The emperor even leads all the officials there to beg on their knees: “We humbly beseech Your Highness, the Crown Prince, to ascend the throne, protect our Great Xia and safeguard all its people.” Lin Bufan firmly refuses, but the emperor says, “Bufan, in just six months you have eradicated pests, advanced farming, quelled bandits, opened the borders, and expanded trade. In half a year, you turned this place of exile into a land more prosperous than...” “Starting today, I abdicate in your favor and will gladly become a farmer in Lingnan. I, commoner Lin Qiankun, bow before Emperor Bufan. Long live, long live, long live!” Lin Bufan is thus forced to take the throne, and the System unlocks its military expansion and northern campaign module, taking him along on a journey of conquest and territorial expansion.
