Gru's efficiency was exceptionally high.
In just a month, news of the three Communication Device options had spread throughout the Bana Continent.
However, most people only knew about the first two options.
The method and scope of spreading the third option were completely different from the first two.
Whether it was the first option, maintaining the current situation unchanged,
or the second option, joining the 'Continent' Alliance and trying the so-called 'Super Intelligence,' news of both was publicly promoted across the entire continent.
The third option, however, was different. It was only communicated to suitable targets, and their opinions were confirmed through this method.
Gru had discussed it with Jie Ning.
After all, entering the Undead Realm was the sort of matter that could cause unnecessary trouble if publicly advertised.
As for Jie Ning's restrictions on those eligible for the third option...
First, age was not really an issue.
Mental power at Level 6 or above...
Generally speaking, it was impossible for a mage with strength at Level 6 or above to be younger than sixteen, unless they were a truly rare genius.
As for warriors, possessing mental power at Level 6 or above meant they had to be among the very best Level 9 Warriors. Ordinary Level 9 Warriors could not meet this requirement either.
This was not Jie Ning targeting warriors. To control undead across Planes, there were naturally certain requirements for the strength of one's soul.
In other words, controlling undead required transmitting a certain amount of Soul Power over there.
Generally, the weaker a person's mental power was, the weaker their soul tended to be as well.
And if the undead creature they controlled died, that portion of their soul would naturally be completely lost.
For those with powerful souls, such losses could still be made
