Douluo: Betrayal of the Blue Electric Tyrannosaurus Rex Family at the Beginning

I became the most despised branch disciple of the Blue Electric Tyrannosaurus Rex family, just because my father combined with a civilian soul master and soiled the so-called "true dragon's blood". At the annual clan meeting, Yutian Henglong, the grandson of the clan leader, was so powerful that he was hailed as the future of the clan. And when I, the "mongrel descendant", came on stage to awaken, everyone was waiting to see the joke. I calmly stretched out my hand, and suddenly the sky thundered, and an unprecedented purple lightning dragon tore through the sky! The test crystal exploded into powder, and the elders stood up in shock: "Is this... The bloodline of the Supreme Thunder?" I looked at the livid-faced patriarch of the clan and sneered: "So, it's you who have soiled the bloodline." On that day, I took my mother and rebelled against the family, and thousands of thunders followed me to see me off.
