Secondary Energy Storage, Hidden Potential

'It's completely silent.'

Although the illusory Dantian wasn't as active as a heart or a lung that were part of the necessities of life, it still showed signs of life comparable to other body organs.

In fact, it also followed the same pattern as the human body. 

Similar to a muscle that could adapt to certain actions and movements through training, with enough time, the Dantian itself could assist with the Circulation Cycles that every Martial Artist used.

With even more specialized training, one could customize that adaptation in a way that would increase Internal Energy efficiency. However, that required extreme control and familiarity with the Dantian.

'Doing that was simple, but this is completely different.'

Now that he had taken the time to give the Secondary Energy Storage a proper check, Leo could summarize the whole difference within a single comparison.

'It's like a transplant.'
