Waking up, a little black snake found himself fallen into a dragon nest, and was surrounded by three young dragons. To save his life, in a rush he opened his mouth and shouted "Mom". Unexpectedly, the Long Jun not only really acknowledged this son, but also arranged three older brothers for him. From then on, while the little black snake tried every means to escape, he was seriously raised as a young dragon by the whole family. However, as the bloodline trial opened, his hidden special identity gradually emerged, and the secret sealed deep inside the dragon clan for many years also surfaced accordingly. Facing the crisis, this most inconspicuous little fellow will also become the key to protecting his family.
