Not everyone with a superpower could join the National Metahuman Squad.
Even if they were not core members, their Efficiency Rate had to reach over 93% to not be squeezed out.
Anyone who could reach above 95% would be considered a core member of the National Metahuman Squad. Of course, there were other assessment requirements.
This Efficiency Rate was not about using all of one's power, but how efficiently one could use their power when quantified.
For example, in Changming's eyes, if the same ability were to be used to injure ten people, anyone from the Tang family only needed half a T3 crystal core's energy, but Lu Yunxiang would need three.
To put it bluntly, it was a type of energy utilization rate. However, those in the National Metahuman Squad didn't need to replenish their energy, so such a concept didn't apply to them.
