McRae did have the teleportation skill.
However, he still couldn't use that skill.
Because that skill had a prerequisite.
Furthermore, he couldn't teleport that far.
Most importantly, that teleportation skill couldn't be used in Stealth.
Once he used that skill, Stealth would automatically fail.
But how did McRae do it!
Limitless!
He used Limitless' bow and arrow.
The release of the bow and arrow meant that the sound was not meant to be heard.
Furthermore, the wind in the valley was very strong.
The wind that blew back directly covered the sound of the arrows.
Taking advantage of everyone's attention, McRae went up and stabbed.
Warriors didn't have many weaknesses.
If this Warrior's back was outside, McRae could still use Backstab, and the attack power of that skill could directly double.
As for the warriors surrounding the iron bucket formation, McRae naturally had no use for Backstab.
