Guilty as charged
It seemed like the regular houses of some nobleman that were a bit on the lower side of their ranks. Two guards only seemed like a small number, but maybe they were mainly there to make sure that the guys behind wouldn't try to take the money and resources for themselves.
Regardless, Rain used Magic Eyes on them and he was unable to confirm if they had the magic bombs inside them. So, killing them even as fast as possible would be too risky… still, unlike the last ones that Rain had seen exploding, they probably would be fine in making them fly to high in the sky.
"I can't risk them alerting the people of the capital of the guys that they were watching notice that I am the one who got rid of them…" Rain rubbed his chin thoughtfully. "My best option is to make them disappear in less than seconds and make them explode in a place that it won't leave any signs behind."
