The players were stunned.
They didn't expect Sam to make such a move. The light elemental fusion is something they are familiar with. Some of them even saw him using the laser mode before. They knew how energy-consuming it is.
They also know how dangerous it is.
If Sam kills the targets with that laser mode, that means, the undead creatures will come with this laser mode in the night mode.
Particularly when they noticed how Sam killed the target, they are sure of it.
He didn't attack the target normally. He didn't shoot light beams, instead, he used the characteristics of the fusion to turn himself into the laser beam and used his whole body to kill the target.
They knew what this means.
Before they could come out of their stupor, Sam already killed the second target in the same way.
"Stop staring and try to stop him. If that asshole finishes them off, we got no chance at night mode."
