Those spirit envoys who were taken away had no commonality at all, but everyday, there would be a batch of spirit envoys being brought out of the Soul Prison, and they would never appear again after that.
At first, Qin Song did not notice anything suspicious about this matter but the words from the boy had reminded him something.
If they wanted to destroy their souls, they could just burn them down with the spirit fire, why would they need to bring those people out everyday?
In the Soul World, the Soul Prison was the only place which was suitable to lock the soul entity up. Where had those spirit envoys been taken too? Were they dead? Or were they still alive? If it wasn't for the purpose of slaughtering them, why were they brought out?
