Lin Jin is the "son of Orion" and is considered a "monster" because of his "naturally red eyes". Once he was bitten by a monster and bled, golden dragon scales emerged from the wound, and he awakened [Blood Pact Reversion] - his blood boiled and turned into a candle dragon shadow, repelling the monster. He took this opportunity to join the "Beast Taming Sect" and used the power of blood to tame high-level monsters.
The villain "Dragon Slaying Society" wants to hunt the descendants of the mythical beasts for their blood, so Lin Jin is forced to flee. After going deep into the "Zhulong Tomb", he discovered that the president of the Dragon Slayer Association was actually his ancestor (he sealed the Zhulong to save the people, but was misunderstood as a "dragon slayer"). In the end, he used the [blood contract to return to his ancestors] to awaken the remaining soul of the candle dragon, reconcile with his ancestors, become the "Guardian of the Candle Dragon", and establish the "Three Don'ts to Return to His Ancestors" (not to kill indiscriminately, not to rely on force, and to protect the descendants of the gods).
