Because of time, space, and money (most importantly), the micro-mechanical work cabin, which is about the size of a cat carrier on her desk, doesn't require spiritual power for its core components, though it's a bit complicated.
Only one core chip posed a challenge; due to time constraints and poverty, the specifications she could afford with small means were insufficient, so she had to use spiritual power to etch and adjust it.
However, if she had enough funds, there is now a chip that can meet the requirements.
With the work cabin activated, the next steps are to inject new materials, fill them with counter-energy, program them, and assemble them...
The process is simple and quick, with no significant difficulty.

Anyway, given her little brother's abysmal academic performance, scoring below 150 in total on college entrance exams, he couldn't possibly understand.
