Landmines

When Lei Zhen heard that the black mage had set up numerous landmines in the muddy water, he was astonished for a moment.

To think the black mage would resort to petty tricks like this meant that it was getting desperate.

"The land mines being set up in the muddy water helped camouflaged it which resulted in the earlier explosion. Though now that we know there are landmines set up, the soldiers can temporarily retreat for the moment." Lei Zhen said calmly, not affected by the slight downfall from their earlier momentum.

If the black mage was that easy to apprehend, then he wouldn't have even bothered to mobilize this many armies for assistance.

Despite that, Lei Zhen was a bit taken by surprise when he realized the black mage was setting up landmines secretly.

This just goes to show that the black mage was doing something very important with the hideout of the previous Lizardark. Otherwise, it should have left from the beginning and not wasted its time over here fighting.
