Weirdness of the Century: the Little Princess of the Royal Family with a Contract at the Beginning

The story opens in a small dark room, and Yin Yuyang is forced to board the princess's pirate ship and leave his hometown. The world is shrouded in [Night of Strange Spirits], and evil ghosts are rampant. Every time the strange night falls, it means longer suffering and death. What is even more despairing is that the duration of [Night of Ghosts] is getting longer and longer each time. Along the way, Yin Yuyang kept making friends: The imperial princess with two souls; A dark unicorn controlled by a ghost; A wolf in dog's clothing... When all living creatures were reduced to lambs to be slaughtered in the darkness, Yin Yuyang held high the contract and declared war on the dark night of the century: "If this world is destined to be eternal night, then I will ignite myself and become the only light!"
