Sea Serpent

After a few days, words spread among the soldiers about divine justice who punished anyone who hurt others. The soldiers who tried to assault their female comrades? They were punished because one of them lost control of his skill.

The soldiers who bullied the weak? Unfortunate accidents would befall them. Then, rumors spread around about a vengeful ghost that would whisper in the ears of others.

Stories were made about the pitiful demise of this soldier, pushed by his comrades into killing himself. After a few days, none of the soldiers dared to mess around anymore.

As for the culprit himself, Nikolai was enjoying himself immensely. There was something about messing with people that seemed to relax him, and he slept in his stealth peacefully.

Although the draining mana would alarm anyone in their sleep, Nikolai learned to deal with it. His body also adjusted to the time cycle of the army, so he woke up before they did.
