Underworld: from the Prince of the Capital to a Prisoner!

He was once the most dazzling prince in the capital, but overnight, he was personally sent to a non-existent prison by his father. "Either die or come back alive like a man!" These were the last words his father left for him. In the living tomb called Longyuan, he teamed up with the King of Soldiers, battled wits with the heroes, lost his glitz, and became a demon through hardening. Live, even like a dog, this is his belief!
