The Divine Plague Curse Technique was developed by Feng Luoyi, a peerless divine skill involving the soul and computational theory.
The history of calculator development in Shenzhou is not the same as the history of computer development on Earth. The computers made by scientists on Earth initially were the simplest "machines," gradually becoming more complex. However, in Shenzhou, it was the opposite. Initially, the two, Cangsheng Guoshou and Elder Ji, imitated the human soul, defining a rough model with mathematics, forming the first calculator. However, it wasn't until recently that Shenzhou arithmeticians discovered the foundational mathematical model for calculators.
Only in a universe more tolerant of "technology black boxes" could such a development route appear.
And the Divine Plague Curse Technique was a byproduct of the early development of calculator technology.
