Jiu Zi Bu Cheng Long

The Dragon Lord has nine sons and each of their personalities are totally different. The flighty young dragon princes were overly energetic, not only did they refuse to work diligently but also caused trouble everywhere they went, creating pandemonium on the Dragon God Island. The Dragon Lord was enraged by his nine sons and will no longer accept their behavior, so he banished them to the mortal realm to train themselves, expecting them to grow up… or maybe not?
