Dai Li had met only one S-level athlete in his long career life as a coach. That was Feixiang Lin. In addition to Feixiang Lin, the most talented athlete he had seen was Feifei Yu, who was level S-minus.
In the National Track and Field Team, level B talent was among the best, and the only A-level athlete from the sprinters was Sijie Yang, who was discovered and trained by Dai Li himself. And the entire National Track and Field Team had less than five A-level athletes, while the S-level group there contained only Feixiang Lin.
So Dai Li had already learned that even pandas outnumbered the level S athletes. These athletes were "endangered species"—there were just a few nationwide.
