According to Chen Mo's demand, those people had to be executed by him personally. It would be impossible for Chen Mo to tell them that executing them personally allowed him to acquire their Divine Power. He simply stated that he wanted to take revenge personally, and there was nothing wrong with that.
As responses from individual Star Systems began to arrive, Chen Mo also started releasing the people imprisoned within his Divine Domain World. As each Star System's representatives arrived, he released the people of that Star System, making his way to their gathering places to harvest Divine Power.
Chen Mo, possessing the Mind Reading Technique, was completely unafraid of them tricking him. Having been forewarned by Chen Mo, those individuals didn't dare to trick him either.
