Old General
The military camp was not as Nathan expected. It was also surrounded by over two thousand aliens.
However, their walls were much sturdier, and there were a lot of basic fortifications, such as ditches, around the military camp.
The knights were actually much stronger. When they saw an alien was about to approach, they killed it almost immediately before throwing it back outside.
Some officers were actually summoners who had abandoned the way of summoners and chose to become a full-fledged knight. Their Ena was much more powerful than Selena and Nathan, but that was because they never summoned another familiar for various reasons, starting from losing their familiar in the past to simply wanting to rely on themselves.
However, the main reason the military camp stood tall this whole time was definitely because of one man.
An old general was standing on top of the wall, his presence turning the surrounding knights to the undying knights.
