She could see how the spiritual power stored in there moved like liquid gas. She also realized that the border separating the spiritual energy and superpower energy in the dantian was no longer a clear line, but had blurred and the two energies were mixing at the border.
She didn't understand what was happening but she assumed that if the two mixed, then she would be able to use her spiritual energy for her superpower and her superpower energy for her cultivation technique.
This was a benefit because she wouldn't have to worry about running out of one when she needed it while the other was in abundance.
Chu Miao sensed around her body to determine the changes and realized that her meridians and dantian had not just become wider, they had become stronger too.
They were no longer as fragile as before, bursting at the slightest aggression. Now, they could handle attacks aimed directly at them.
