Just that they can resist it and notice it. But if he suppresses them he can then have it slowly take them over.
I believe that they only took care of the members that were a part of them. The rest of the Raiders changed the location of their base when they realized what was going on. And it seemed like the strongest people in the Raiders 100% got away. So LH will need to take care of them, unless of course they left the Universe.
I mean it was solely because the author made him act dumb. Wouldn't have needed the plot armor if the author didn't make him do things he wouldn't normally do. I mean he can literally freeze time and cultivate with all the resources he harvested and increase his strength by multiple factors before going to a place that he thought was deadly... But nope, author wanted us to have this plot armor chapter.
Why he wouldn’t use the gate to go cultivate before going to a place that could potentially kill him is dumb, but understandable for the author to create tension… Only issue is that it is incredibly artificial tension caused solely by the author choosing to make LH be dumb.
