Su Yang couldn't be bothered to deal with him. In fact, Su Yang could vaguely feel that Heaven Slayer was actually always accumulating power. Heaven Slayer should also be returning; he couldn't always intervene to assist Su Yang because he needed to gather power for his own return.
Otherwise, just relying on Heaven Slayer's illusion, Su Yang wouldn't fear those Guardian Gods.
However, forcefully using Heaven Slayer's illusion would not benefit Heaven Slayer at all. Su Yang didn't want these trivial matters to affect Heaven Slayer's path to return, as the return of Heaven Slayer could impact the fate of the Human Clan!
Therefore, Su Yang couldn't use Heaven Slayer's illusion every time, especially when dealing with those Guardian Gods at the Earth-level realm.
