Demon Lord Nine Calamities heaved a sigh of relief as if he felt a massive burden had been lifted up from his shoulders as his Divine Sense checked out the dumbfounded expressions of the demonic cultivators and the frustration on the Wrathful Asura King's face.
Qing Yunzi, the Sword God, was an old friend of his before he became a demonic cultivator.
They had countless confrontations with each other after that, yet the Sword God almost always bested him, sparing his life again and again just for the sake of their past brotherhood.
The Sword God even fought against the Wrathful Asura King once, and had it not been for a Dharma Artifact the Asura King used at that time, the latter might have died by the former's blade. With the Dharma Artifact, the Asura King was able to overpower the Sword God and even managed to severely injure him.
