Lin Jun's practice of "Soul Touch" certainly couldn't just squeeze a D Level personnel to death instantly.
The ten who died before were simply special cases used to thoroughly understand the skill's effects.
Normal training would definitely involve damaging a small part of the soul, then waiting for it to recover before damaging a small part again, sustainably draining it dry.

In the past, adhering to the principle of sourcing locally, only the local villains of Mushroom City were eligible to be recruited as D Level personnel.
Other towns were too far from the Underground City, making them difficult to transport back even if captured.
Apart from the stable talent supply market of Mushroom City, occasionally spies sent by the Empire to the Northern Territory would fall into the net as an extra gain.
