As the family stopped talking about their advancements, Chu Miao went back to the pool that had been completely drained of any spiritual energy.
There was only a complicated pattern at the bottom. She realized that she had been right about the array at the bottom of the pool.
There was an ancient array there used to gather spiritual energy and hold it in the pool.
This, it wasn't just a spirit gathering array, otherwise, the spiritual energy would not have been contained in the pool and be scattered everywhere in the hall.
She wanted to understand the array formation so that she could make one like that later once their sect was ready.
When the others saw Chu Miao take out pieces of paper and pen and sit down at the edge of the pool, they understood what she was about to do and couldn't help but feel that they were going to be there for a while.
