The Peerless Crown Prince

After transmigrating into the Great Zhou as Crown Prince, I expected a life of fine clothes, good food, and beautiful women behind silk curtains. But my younger brother watched me like a tiger waiting to pounce, powerful ministers ruled the court, the treasury was empty, the people were starving, and foreign tribes were watching us hungrily... Li Qingyun had no choice but to pick up the blade he should never have put down: execute the treacherous prince, eliminate the conspirators, amass a fortune, win the people's hearts, and crush the enemy nations.

If I transmigrated here, only to obey Heaven's will and reign forever, what was the point of transmigrating?
