From an unofficial (and somewhat grammatically atrocious) English translation of the original novel [0]:
> Normally, Eru would have given up at this stage and would have chosen a more practical spell. But he knew how to solve the problem because of his unique skills ― programming concept. He had experience in designing and coding software to handle multiple variables. That's why he skipped the beginner magic phase and jumped straight into the 'modified magic' phase. Reviewing the structure of the physical boost script, Eru compressed the structure to minimise the number of variables, creating subscripts that would automatically extract the status of the body. After compiling it, he just needed to design the user interface to make it easier to control, so as to lessen the burden.
> Complicated projects like the improvement of scripts was not something that could be done easily by anyone. Eru, however, was not aware of this, completing the improvement shortly, and the patch was a big enhancement. But even so, it was still difficult to control magic that strained the mind heavily. But with his extraordinary processing ability, it was not much. No one realised that a historical revolution had occurred, but for Eru, this was just a small step in his journey.
