"Now, let's see how you are going to protect yourself now."
Since there was nothing that could protect the elemental spirits now, the old man decided to kill them before leaving this place.
The old man knew that since his elders' brothers were unable to survive against the summoning master of these elemental spirits, he would not stand a chance against such a person.
Before that, killing the elemental spirits was a must for him because he wanted to avoid the birth of the inner demons in his heart.

A few moments back at another place,
'Fog Storm'
The Ice elemental spirit used one of his skills to block the vision of the old man.
'Swoosh'
In the next second, a huge Fog Storm appeared that spread throughout the entire location.
Even though it looked like normal Fog, in fact, it was not and it was enough to temporarily block the old man's vision.
'Poison Screen'
