Is the song of cloud Pliocene world and city a game spoiler?

Yes The song of the city on the cloud is a very popular adventure world game tour under Sanqi Mutual Entertainment. Maybe some players haven't heard of this name, but there are many games with the same name in this game. City of the Brave, Song of the City on the Cloud, Enchanting the New World and Adventure in the Abyss are all games of the same name, so these two belong to one game.
