"In Country Hua, there are numerous schools of National Martial Arts, but there exists a universally recognized ranking system for strength, passed down since ancient times.
That is, the stages of practice for martial artists are divided into Light Force, Dark Energy, and Transformative Energy.
Light Force transforms the bones. At this stage, practicing boxing mainly focuses on using bone power, aiming to return to the origins and transform the body into pure Yang, similar to the vigor of a newborn baby.
The so-called heavens are vigorous, and a gentleman should continuously strengthen himself.
A person at the Light Force stage is spirited, bold, and fearless.
The further one's practice deepens, the more the person exhibits a remarkable disposition, standing out conspicuously in any crowd, demonstrating brave valor.
Like most of us ordinary folks, we remain at the Light Force stage for our entire lives.
Following Light Force is Dark Energy.
