Douluo V: the King Who Emerged from the Core Area

… Douluo... I'm coming...! "Who are you?" "My name is Na'er, look good! I know, you are my brother! I am very strong, and I will protect you from now on..." The host is detected to complete the achievement: "I have a Dragon King sister", which gives the martial soul a chance to evolve to the top level. It has been used automatically... Used successfully, the current martial soul is the Shadow King! The only human being who came out of the core area... Or a king... When I stand at the top, everything is mine, no matter the protagonist, master, or horse, all sit down for me!
