Wolfgang said he wanted to examine Gao Yang by slicing, although it was not possible to actually slice him, a thorough physical examination was naturally unavoidable.
When a person demonstrates capabilities far beyond those of an ordinary person, there are only three possible explanations: first, this person possesses a unique physical structure; second, this person has undergone training; third, this person's physical fitness is extraordinarily strong, and they have also received professional training.
Wolfgang had to know why Gao Yang had greater endurance than others. If it was because of innate talent, then it meant nothing. Geniuses were special because they could not be mass-produced. However, if Gao Yang's physical condition was not exceptionally strong, then it was necessary to study what kind of training Gao Yang had undergone.
Gao Yang was examined inside and out, thoroughly, and all this was completed while he was sound asleep.
