Doctor Yang obtained much of his knowledge from the system space.
For instance, he gained extensive knowledge in human anatomy through countless dissections conducted within the system space.
Under such circumstances, he could only use this knowledge temporarily without publishing it as part of a paper.
As Doctor Yang had no time to arrange his own anatomical research, the acquired knowledge could not be traced back through real-life experiments.
Even in surgeries, Doctor Yang applied the surgical experiences obtained from the system space to real-life cases, publishing papers based on these cases.
The same approach was taken for scientific research, which required the full process to be carried out in reality.
Medical results had to be traceable in reality. Doctor Yang couldn't arrange all the real-life experiments based on the system space's results at once, so he prioritized them according to their necessity.
