In the Dragon Clan, young dragons are always accompanied by adult dragons until they come of age. Ordinary people can't even come into contact with young dragons, but in the special place that is Doomsday City, the adult Black Dragon had already been slain by dragon slayers, allowing Song Jian to stumble upon a bargain and sign a War Pet Contract with a newly hatched Black Dragon.
Actually, signing a contract with a member of the Dragon Clan is an extremely difficult task, but the power of the game system was so overwhelming that the Dragon Clan had no power to resist, and Song Jian easily signed a War Pet Contract with the young Black Dragon.
