The prosthetic body with extreme weight reduction was actually an important... a very significant project proposed by Xiang Shan.
The simplification of the internal structure came from an experiment.
Once again, when Lu Xuanyu submitted the experiment report, he mentioned the tactile sensation of the prosthetic foot. This report naturally drew significant attention, with Chen Feng, Tao Enhai, and other relevant field leaders gathering to study the issue.
Because that particular prosthetic foot actually didn't have "tactile sensation."
Subsequent inspections revealed that it was not a mistake by the intern regarding the prosthetic. The surveillance showed that when Lu Xuanyu felt the tactile sensation, he indeed wore an experimental prosthetic without a pressure-sensitive resistor.
