The Invincible Crown Prince

After transmigrating into the Great Qian dynasty as its crown prince, he had hoped to live in luxury, surrounded by beautiful women. But his younger brother was watching him like a tiger eyeing its prey, powerful ministers ruled the court, the treasury was empty, the people were starving, and foreign tribes were poised to invade... Zhao Wugou had no choice but to pick up the blade he should never have put down: execute his treacherous younger brother, crush the rebels, amass wealth, win the people's hearts, and destroy the enemy nations. If you transmigrate here but refuse to accept Heaven's Mandate and reign for all eternity, then what was the point of transmigrating at all?
