Exiled to the Northern Frontier? I’ll Raise an Army and Crush the Imperial Capital

He is Fang Yun, the most inconspicuous of Great Xia's six princes. One day, he is falsely accused and banished to the bitterly cold northern frontier, all to enhance the Crown Prince's reputation.

Everyone thinks he will die quietly along the way to exile. They don't know that he carries a treasure trove of modern knowledge and has awakened a sign-in System, setting foot in this desolate land forgotten by the world!

Before Zichen Hall, he once argued his case with reason, only to be scorned by the assembled officials. On the road to exile, he uses modern knowledge to solve one problem after another, and gains all kinds of help from the sign-in System, astonishing everyone! When the prison cart reaches the northern frontier, and he steps into this land of challenges and opportunity, [Ding! Sign-in successful at Northern Frontier Border!]

[Congratulations, Host. You have received a basic farming tool set!]

He begins using his modern knowledge and items obtained from sign-ins to clear fields, smelt fine steel, and train iron cavalry.

[Ding! Sign-in successful at Newly Built Workshop!]

[Congratulations, Host. You have received a secret formula for smelting fine steel!]

[Ding! Sign-in successful at Martial Arts Training Ground!]

[Congratulations, Host. You have received a cavalry training manual!]

With the System's help and his own hard work, three years later, his iron cavalry sweeps across the grasslands, and even princesses kneel and beg to marry him... Only then does the one on the Dragon Throne finally realize his mistake: the man he personally exiled was no discarded pawn, but Great Xia's true hidden dragon! “Your Majesty, this vast northern frontier... belongs to me now!” It turns out exile was the beginning of his rise to supremacy!
