Zhou Chuan immediately released his Soul Power to envelop the Butcher's Divine Soul, using his own method to search his memories. If he had used his divine sense to forcibly extract memories, his own divine sense would have suffered a backlash, compounding the damage to the Divine Soul and accelerating its death. There was a good chance he wouldn't have gotten any memories at all.
The time of an incense stick passed. He should have stopped, but Zhou Chuan instead intensified the search. His purpose in searching the soul was to learn more about the Butcher's Nascent Soul in order to decide how to slaughter him. As it turned out, the Butcher was harboring a secret, and Zhou Chuan had stumbled upon it accidentally, immediately catching his interest.
"So the Butcher is the grandson of the Beast Taming Sect's fourth Patriarch, making his status far more precious than Lian Shuwang's. The Beast Taming Sect has eight Patriarchs, every single one possessing a Deity Transformation Cultivation base. I once saw one of them, though that particular one was not even the strongest."
