Every living creature had limited potential.
That potential would be the deciding factor for the upper limit. It was like a bloodline.
However, potential could be improved. As a trainer, Su Ping successfully did just that.
An excellent teacher could teach so well that a kid who failed an exam would get a full score in the following test. However, when it came to geniuses, getting a full score was just the beginning; it was normal for them to skip grades. That was the difference in upper limit between geniuses and ordinary people.
There was a huge gap in intelligence.
Even the most distinguished teacher was unable to improve the upper limit of an ordinary person to that of a genius, unless they were gods!
