What Will Suffice?

Ingrid started bringing the slaves to Aldritch one after the other. Since they were under his control, all of them were obedient and followed her orders without resistance. Aldritch wouldn't have gone through such a long process, but it was necessary. He wanted to avoid them breaking out of the control due to shock by all means possible, which would only be bad for him and make things stressful to deal with.

The first person walked towards Aldritch by the side of the river, and once he got to him, Aldritch wasted no time. With one swing of his dagger, he slit the man's throat, giving a smooth passage for the blood to gush out. Before the blood could touch the ground and flow into the river, Aldritch used his skill 'Blood Manipulation' to hold the blood midair so it didn't spill and create a mess around, though he was standing in the shallow river edges, so it would have still mixed with the water and flow away.
