The reason Ye Qian did not feel it clearly was because her Water of Purification had always been purifying the part of the power within her body that was harming her.

After the Water of Purification neutralized with Pollution, if excess Water of Purification remained in the body, it would continue to work until it naturally dissipated or was expelled from the body.
"If the above three points are correct, then perhaps I can make even more deductions."
That would be the fourth point.
4. Pollution and Life Energy naturally attracted each other. The human body naturally possessed more Life Energy than Pollution. The more Life Energy one had, the easier it was to attract surrounding Pollution.
This could be understood as pure Life Energy being unstable, like an atomic nucleus that naturally attracted electrons.
And the more Life Energy there was, the stronger its attraction toward Pollution would be.
The less there was, the weaker the attraction.
Ordinary people who had not reached Black Iron Rank were born with Life Energy, but they had very
