I Have Become the World-Destroying Dragon God, but the Empress Is Only at the Second Level?

Lu Yuan traveled through the world of spiritual energy recovery and became a little black snake in the mountain of 100,000 forbidden areas for human beings, awakening the [Wanting Women to Become Dragon System]. As long as the contract partner breaks through, he can unconditionally be five realms higher than the other party! He originally wanted to live forever in the restricted area, but unexpectedly, the human empress who died in battle in her previous life came back again, broke into the restricted area and insisted on signing him as the beast master. Empress Luo Qinghan: "Little black snake, be my beast master, and I will give you the opportunity to transform into a dragon in the future!" Lu Yuan rolled his eyes and reluctantly signed the blood contract. A few days later, the King Wu-level enemy who killed the empress in her previous life came to visit. Luo Qinghan was about to fight to the death, but he saw the "little black snake" on his wrist turned into a black dragon tearing apart the sky, and with a flick of the dragon's tail, King Wu was whipped into blood mist. Luo Qinghan was dumbfounded: "I am only a second-level warrior, and you call this a little black snake?! Who is leading whom to fly!"
