I, the Child Protector, Hunt the World-Destroying Mad Dragon

We robbed the "goods" of Coran Castle. When the black cloth was lifted, my life was completely torn apart at that moment - there was no gold or silver in the cage, only childish spirits exuding the halo of morning light. The leader wanted to silence them, but I insisted on sending them back. I thought this was salvation, but they used the child spirits as "materials" and prepared them into big cakes to feed the war pterosaurs. However, in the deepest part of the castle, I glimpsed a more terrifying truth: The origins of these child spirits are being extracted into the ultimate secret war medicine that plunges pterosaurs into absolute rage - "Child Spirit Blood Essence". When the sky is obscured by a crazy dragon injected with child spirit blood, the earth will be torn apart by pure animality. And I, the witness of this heinous crime, was chosen by the eldest lady Natalie. She wanted to forge me into an equally loyal and crazy killing weapon, and build a pterosaur empire for her. She failed. The blood of the ancient beast awakened in my body, and it brought not madness, but the coldest and most thorough will to liquidate the evil that plundered the origin of the world. When the horn of war sounds again with childish cries, I will return. Use the magic sword to hunt every bloody crazy dragon. I'm Jon. He was once an unknown cook, but now he is the last guardian of child spirits in this dark era.
