1:10!
The flow of time, can actually be slowed down to 1:10.
This disparity in flow exceeds his imagination.
Regional Time Regulation is completely different from adjusting the time of objects.
He can also rapidly age himself, but the development progress won't change at all; essentially, it's a manipulation of singular time information.
Only by regulating the overall environment can he use this time flow disparity for development.
And this is a change to the Universe, destined not to be very high.
He originally guessed it might be 1:5, but didn't expect it to be 1:10, what a sudden surge.
Calming his mind slightly, he instinctively estimated that reaching a 1:10 disparity, even if it only envelops him, would significantly increase the cost.
Even with various abilities and potion recovery, continuous regulation for three days would require one day of rest.
"In this situation, advancing 1% of my development progress would take about thirteen days."
