Chen Xiu's heart was calm like water. With his head lowered, he spoke in a calm tone without showing the least bit of emotion. He had thought about what he would say previously, since if he admitted in front of Asura that he had killed Ming Xiu, he would really be courting death.
What sort of person was Asura? He was the ancestor of all the residents of Asura City and an innate ancient god. He knew everything about the clan treasures which could raise anyone's cultivation to god realm temporarily.
Ming Xiu had used Asura Eyes to raise his cultivation to god realm, so how could he, who was at the ninth layer of great flux expert realm before, him? It would be a big gaping hole in his narration if he said it like that.
The best justification was to have a holy daughter, who was also a god, personally attack him.
