This was actually because they were from the same race.
Yes, after discovering the usefulness and uniqueness of Ghost again and again, Michael had not wanted to overcrowd his undead legion with one major type of undead, but he did realize that sometimes having more of a single type was simply better.
Ghost type happened to be one of those cases.
Physical strength that could compete with a pseudo level seventy as a new rank three creature was not common at all, and even the ones Michael had not used materials on could fight with level sixty-five creatures even as early rank three undead.
Not all creatures were naturally strong.
There was also something else about the ants.
Their laws.
It was a collective law.
Another discovery that made Ghost's race even more mythical.
Ants were a strange species.
From the moment they were born, their lives were already decided for them.
Workers worked.
Soldiers fought.
And some reproduced.
