The extractions had reached the last stage; 96% of Grimm's constitution had already been extracted, the extraction of the last 4% would be finished in a few minutes, and the gates of the artifact would open soon after that.
I looked at humans, especially a few unconscious ones, the spies. The Grimms have kept the spies among the enslaved humans.
The Grimms are extremly smart and learned through thousands of years, which is why they give barely any chance to the large rebellion.
If there is something happening, Grimms wants to know about it and be prepared to deal with it. Of these five thousand people, there are one hundred and twelve spies, and what makes them dangerous and hard to detect, not all of them have a free seal.
A minority, less than 1% of them, have restricted seal-like others, which makes it really hard to see them as spies as their seals are the same.
