The middle-aged man's name was Hai Zhu. At the moment Wang Lin cut off his head, Wang Lin sealed his origin soul. With Wang Lin's Ascendant stage cultivation, it was effortless to seal the origin soul of a late stage Soul Transformation cultivator!
Wang Lin took the head and left. He was like a spring breeze that disappeared in the blink of an eye. As for the Emperor's jade, he didn't take it back because it was useless to him.
However, it was something the Demon Emperor gave as a sign of good faith. If he hadn't accepted it, he would have appeared a bit too domineering.
As he rushed away, he didn't turn around to look at the 10 million demon soldiers at all. He stepped into the air and disappeared.
