Sixteen transcending the tribulation

After Venerable White made his appearance, the invisible sword insects retreated to one side, not daring to breathe.

Actually, Venerable White himself was also very curious as to why the invisible sword insects were this scared after seeing him, even to the point that they didn't dare to attack them.

Invisible sword insects were extremely fierce bug-type spirit beasts that feared nothing, not even death. Their strength was around the Fourth, Fifth Stage, and they were totally invisible—not even the mental detection of cultivators could detect them. To ordinary cultivators, they were as deadly as a wild Zed for LOL players.
