欺我者皆拜龍神

The illegitimate child Layne, who suffered constant abuse from the nobility, carries the blood of ten thousand dragons. He becomes a disciple of the first Dragon Tamer King, shines in the royal tournament, discovers the truth about his dragon-princess sister from the Dragon Realm, fights against the Dragon Realm Lord and the corrupt nobles, and ultimately awakens the power of the dragon god to overturn the continent's monopoly order.
