Although Bai Zemin's clones only contained a basic 10% of his total power, that 10% could by no means be underestimated. Considering how monstrous Bai Zemin's stats were, that 10% was more than enough to practically overwhelm any enemy below the First Order.
Since the clones were using the outer perimeter of the forest as a hunting ground, there wasn't much chance of a First Order beast appearing in it.
If it was Unclassified beasts, Bai Zemin believed that his clones could take care of it without any problems as long as they did not appear in large groups. After all, his clones could only use pure physical strength without any active or passive skills; one had to remember that Bai Zemin's skills were deeply engraved in his soul with runes. His clones did not contain part of his soul, they were just an extension of one of his skills.
