Using "Aunt Flo" as an excuse, Su Tang holed up in the cave for several days, diligently studying the basic cultivation methods until she finally began to see the light.
At the very least, she had figured out what her superpower was!
Following the practice method's instructions, she guided the Primordial Power within her body to the specified location, then used her will to activate it.
So when Su Tang correctly activated Primordial Power for the first time, causing a black hole surrounded by a halo of blue light to appear in front of her, her excitement was indescribable.
After several days of groping and getting familiar with it, Su Tang finally understood what her superpower was all about.
The 'black hole' she created seemed to connect to a different dimension, and she could set the size and number of 'black holes' as she wished based on the storage of her Primordial Power.
