Instructing Su Wuhan to continue his attack on the Star Shattering Sect to avoid drawing the attention of the stronger demonic cultivators, Xuan Hao made sure that he wouldn't end up harming any disciples or elders of the sect and would only be fighting with the winged lion demon beast every now and then.
In case some of the disciples or elders of the sect were in a dangerous situation, he also made sure that he would be there to secretly lend them a hand against the demonic cultivators. Ensuring that the disciples and elders would be able to train and grow in their battles against the demonic cultivators without too much risk.
Although this was only one of the two places where the Star Shattering Sect was under attack by demonic cultivators, the other border wasn't attacked by any demonic cultivator above the First Demonic Transformation Realm. Meaning that the Domain Lord Realm elders didn't even have to do anything, as the Nascent Soul Realm elders of the sect took care of them.
