Both Professor Huang and Ling Ran said nothing on their way.
Older people did not care about stuff like Cybertron [1] and Nebula M78 [2] at all. They would just sense the great evil that was the generation gap when they heard about such things.
If it were not for the fact that Ling Ran was the best hepatobiliary surgeon he knew, Professor Huang would have changed his mind right then.
Unfortunately, it was very hard for a person to fake his skills.
This was especially true when it came to surgical skills. Truth be told, after watching Ling Ran operate, Professor Huang did not even trust the two hepatobiliary surgeons he knew before this anymore, even if they were already chief surgeons.
To a certain extent, Professor Huang got to witness Ling Ran's exponential growth for himself.
