Son of the Dragon, Lord of the Underworld

The underworld is an independent world beyond the scope of the three realms. Our male protagonist is the son of a dragon and died protecting his father in a battle. In order to bring his beloved son back to life, the Dragon King used the Dragon Pearl he had cultivated for thousands of years to resurrect him. Because the magic power of the Ten Thousand Years Dragon Pearl is too strong, although the male protagonist was resurrected, he was afraid that he would take revenge, so the Dragon King sealed his memory and sent him to another world. What will happen to the male protagonist in the end? Without further ado, let's start a new journey. This novel and its characters are purely fictitious.
