Rod instantly tensed up, realizing things could be much more troublesome if the enemy were human.
It was hard for him to gauge how strong a person was. The soul waveform of a person could be hidden and altered. They didn't maintain the operation of spiritual energy all the time like monsters. Generally, spiritual energy only burst forth when they were attacking or about to use a certain ability.
However, humans' defensive capabilities were weak. Before they activated their spiritual defense, he could kill a person with just a light strike without even needing his spirit gun's heavy strike.
But he couldn't be certain they weren't allies. What if they were?
If he ended up with the crime of killing an ally, all his efforts up to now would be ruined.
Rod hesitated for a moment, then decided to test the waters first.
