A Dao Transformation Level of 100% means one's fundamental essence has reached the critical point of completely converting into unobservable matter, needing only to make that final leap.
To go beyond 100% means to draw infinitely close, yet never truly arrive.
This is because that last sliver of observable matter—be it flesh and blood, spirit, inspiration, or comprehension—represents the "unknown" itself, something a Cultivator at their current realm cannot understand or control.
The final leap requires completely abandoning this last bit of the "unknown," forcibly converting it into unobservable matter.
And this process is perilous, with only a slim chance of survival.
It is like pulling the most critical block from a tower, causing the entire structure to collapse.
Succumbing to Dao Transformation.
Even if one is fortunate enough to survive, it is easy to lose one's sense of self—for the self to no longer be the self. This is called the "Heart Demon Tribulation."
