Money is very important.
The prerequisite for publicizing the basic theory of anti-gravity technology is the ability to purchase high-tech products and materials needed.
At the same time, the research and development of anti-gravity technology also consumes a considerable amount of funding, which must be recouped.
The research and development funds for anti-gravity technology are not high because it doesn't involve large experiments. The primary material needed is mostly high-energy light beams, and two weeks are enough for experimental preparation. Coupled with about a year of development time, the investment in research funding is not significant.
However, knowledge is also money.
Zhao Yi considers his knowledge priceless, and entities like the Aviation Group and the military agree that the research funding must be multiplied and earned back.
By how many times?
