Sacrifice

"you all have no reason to stay idle any longer. He plans on taking out the three of you, so he can fully concentrate on me" (first general).

"keep your guards up, or you might end up losing your lives" (first general).

The first Goblin general, warned the other three goblin general's with an alarming tone, on what the Goblin is trying to achieve.

The Goblin generals, especially the second Goblin general, felt angry that the Goblin would treat him the same as some third rate warrior, thinking he could take him out that easily.

"I didn't want to intervene so I won't have to kill you, but you have just pushed your little luck now Goblin" (second general).

The Goblin ignored the threat of the second Goblin general and used his soil Elemental to turn the hard walls, slowly dissolving it to becoming more sandy like.

He controlled the sand gotten from the wall, and dispersed it into the atmosphere to block the vision of every Goblin present.
