Dragon's Back Orphan

I have known my thief as my father for twenty years, but I have treated my enemy as my benefactor. The Great Flame split, and the Dragon Spine emerged. I was raised by the remnant party, equipped with a mechanical spine to avenge my parents, and vowed to slaughter the new government party. In a bloody battle with twelve demigods, facing the Almighty King, the enemy leader suddenly recognized the family heirloom necklace around my neck. "My child, how can your mother's dragon's spine resonate with the blood of someone who kills a relative and an enemy?" The adoptive father's kind mask instantly shattered, revealing a terrifying conspiracy to overthrow the dynasty. And that General Xia Zuo who invited me to drink tea and persuaded me to turn around, the deep meaning in his eyes when he smiled and sipped the tea... Is this spine a weapon of revenge or a string to control a puppet?
