Han Xuhan pondered for a long time before coming to a firm conclusion.
Whoever the creator of this technique might have been, there was no way they could've foreseen this particular situation;
where a cultivator summons souls from an unknown realm and stuffs them into undead vessels, and then finds a banned, unorthodox, 'unregistered' Mystic Art to make these beings cultivate.
Then he strengthens their foundations to the point that they become partial owners of his own foundation tower, and then uses the intermixed spiritual authority to abuse the hidden benefits of this Mystic Art.
What Han Xuhan was doing right now was a more roundabout version of letting multiple non-registered users log in through a single ID to access members-only resources.
Moreover, these users shared the same login 'device' and planned to upload their learnings into the same 'skill-tree', ensuring that nearly every nook and cranny of the Mystic Art would be explored and comprehended.
