When Ye Tianfan smashed his fist down, he never considered that this punch would be effective against those extramural creatures.
After all, even though he possessed vibrating power, and vibrating power is indeed a type of rule power.
However, his vibrating power strikes the air, causing the air to shatter and produce vibrations. These vibrations then attack the enemy.
But if he wanted these vibrations to carry rule-like powers, Ye Tianfan's current abilities couldn't achieve that. What he could do was only make direct contact with those extramural creatures with his fist for rule-based damage. Currently, Ye Tianfan's attack was merely ranged vibrating power, rather than the transparent vibrating power imbued with rule power.
Ye Tianfan actually wanted to touch these extramural creatures directly with his fist, but it was impossible. Just the toxin from this vine-like extramural creature would make it impossible for Ye Tianfan to get close.
