"Soul Control" 

Manipulating souls sounded easy, but to manipulate a foreign soul to explode themselves, it was definitely not easy, which was why the transmigrators were all 'locked' inside the domain so that even if they wanted to resist, only their souls could resist to a certain degree. 

At this moment, the soul experts gathered around the meeting room were twice as many as the number of the transmigrators inside the meeting room. 

The world union probably gathered almost all soul experts that they could find, and even soul ability users below a certain strength level were still hired because if not, where would they get as many as 400 soul experts? 

Any abilities related to souls had always been rare, maybe even rarer than people with space fragment abilities. 

After all, this world focused more on the physique and not the soul, which was why soul ability users were not as developed as those outside of this world.
