Great Tang: Sign-In at the Frontier, Father Begs Me to Take the Throne

[Tang Dynasty + Sign-In + Invincible + Struggle for Supremacy] I’m the most useless prince of the Tang Dynasty. From the start, the crown prince frames me, and my father banishes me to the frontier to die! But they never imagined that I’d activate a god-tier sign-in System and summon a hundred thousand Snow Dragon Riders! The Turks invade with an army of two hundred thousand? I capture their khagan alive on the battlefield, and overnight I become the king beyond the frontier who makes the entire grassland tremble! Then one day, I arrive at Chang’an with an army of a million gods and demons. My father looks at the invincible troops behind me and is utterly terrified. I take out the Imperial Seal and say calmly, “Father, you can’t hold on to this empire. Why not let me rule it instead?”
