Although Zhao Yi only said a few words, each one must have been crucial, or Academician Chen Zeshu would not have shown such a response.
So... simple?
For Zhao Yi, it truly was very simple; but for them, the 'ordinary people', it was as difficult as reaching the heavens.
The former is correct.
In Zhao Yi's view it was indeed very simple, for one, because the input shielding pump already had a foundational design, overcoming some technical challenges.
Secondly, there are more advanced and complete technologies internationally.
After using the "Supervision Law" and the "Derivation Law", he hardly spent any energy before he pinpointed the deficiencies in the design.
In fact, there's another important reason, the design for the transmission pressure pump is indeed simple, and in terms of complexity, it doesn't even compare to an industrial spindle. The difficulties encountered are only in design.
