Summoned Back to the Capital from the Start, I Signed In as an Earthly Immortal

[System + Invincible + Decisive and ruthless + No do-gooder heroine + Prodigy rivalries + War of a Hundred Dynasties] After transmigrating to a fantasy world, Ning Cangsheng becomes the Ninth Prince of Great Qian. With his maternal clan in decline, his brothers force him to the North Sea.

Caught in the capital's power struggles and the battle among nine princes for the throne, Ning Cangsheng is framed. Emperor Qian summons him back to the capital with an edict. His fiancée curries favor with the powerful, seizes the chance to break off their engagement, then throws herself into the Second Prince's arms.

His brothers frame him, the emperor distrusts him: he is already trapped in a dead end.

Just then, he awakens an Emperor-grade sign-in System that lets him choose any location to sign in. The more famous and storied the location, the richer the sign-in rewards.

To his father: “Father, please abdicate!!!”

To his enemies: “I'll suppress every last one of you!”

To his ex-fiancée: “Sorry, I didn't wipe out your whole family because you broke off our engagement. I did it because you damaged my gate and ruined my mood when you did it!”
