He had someone who could trick people and hide their presence using a different method than illusions.

�Meeeeeow-!�

On and Hong stopped rubbing their bodies on Cale�s legs and looked up at him. White smoke started to surround On before spreading out.
She seemed to have understood Cale�s intentions as she had prepared to use her fog in advance.
Cale had asked Raon to quickly bring On and Hong over.

� Human, are we going in?

Cale took a step toward the mountain.

�We are infiltrating the mountain.�

It was quiet at the foot of the mountain, but they might hear weapons clashing or people screaming once they entered.

Furthermore, the chances of those screams belonging to their allies were high.

�Our first goal is to reinforce our allies and save them.�

Cale entered into the forest.
The shadows of the trees made the forest dark even though it was day time.

It was an urgent situation right now.
That was why Cale gave an order that was different than usual.

�Our second goal� Is to get rid of the enemies.�

The gazes on the faces of the assassins of the Molan household quickly changed.

�Our third goal is to identify the enemies, however, if that may lead to injuries� Then we will immediately escape or focus on our second goal.�

Both the first and second goals were focused on saving as many of their allies as possible.
Ron walked over toward Cale without making any noise and then asked.

�Young master-nim, which direction do we need to go?�

Squeeze.

Cale tightened his grip.

Ooooooong-

The top�s whip in his hand was continuing to shake unlike usual.
Cale heard two of the three Wind Elementals that always moved around with him. One was with the Elves in the mountains right now.

�C, chaos, destruction, anger! Elementals are screaming all over the mountain!�
�I hear Elementals fighting all around the mountain! No, that�s not it; they seem to be running away!� JrNovels.com
