The Tides Of War.

Kelvin felt like he was within a storm. The insects around him had rushed him and pressed on him with so much weight that he almost fell down. 

But when he activated his ability, they were the ones to fall down. A large gap that was a kilometer across appeared with him at the center in the midst of the insect storm.

The gap was being filled by insects, but the speed at which he was killing them was too fast for them to fill up the gap completely. He even had to move to other areas to kill more insects. 

As he was doing so, he was earning merit points by the tens of thousands. After all, each insect was worth one merit point. 

It was a pity that they weren't worth any kill points, but he couldn't complain much because of the constant sweet notification of his merit points increasing.

There were other soldiers who performed admirably too. In fact, there were a lot of them because the insects were weak individually.
