Douluo Dalu: Mosasaurus Embers

The dragon clan of the ancient East China Sea suffered a catastrophe, and the royal civilization that lasted for hundreds of thousands of years was reduced to scorched earth overnight. Ao Jinyuan, the last royal family, used the power of space collapse at the last moment of the destruction of his clan to carry the Dragon Clan's most precious treasure, the Cangyuan Dragon Tooth Blade, and drifted across the Douluo Continent where martial spirits were rampant. The dragon power that once made great changes was banned by the rules of another world, and all his cultivation levels were reduced to zero. Starting out as a lonely young man living in a foreign land, he took root in the world of soul masters, using the residual blood of the dragon clan as his root and the top-notch sword weapon, the Cangyuan Dragon Tooth Blade, as his blade. Carrying the deep past of the demise of his entire clan, he honed himself in the battle of soul rings and moved forward step by step in the strife on the continent. The hatred of the old world lingers, and the bonds of another world quietly grow. When the dragon roar of annihilation resounds throughout the world again, the struggle of the last remaining dragon begins.
