Douluo: Legend of the Dragon King: Voice of the Purple Emperor

The battle between the Dragon Kings... the peerless genius... this era is exceptionally glorious, but filled with endless blood and chaos. The invasion of Douluo from the abyss plane, the existence of the Holy Spirit Church, the revenge of soul beasts, the raging sea, the development of soul guide technology, and the emergence of mecha battle armor all make this unprecedented battle for the Dragon King far from being so simple.
