The Soothing Lake wasn't small at all. It was actually huge.
There was no mud or sand at the bottom of the lake, nor were there any water plants. Instead, the bottom was a wide and flat stone surface.
When Jiang Chen arrived, he found people practicing. They were so still that he had thought they were stone statues.
He had tried to be as quiet as possible so that no one would be disturbed.
Not until he had swum to an empty area did it occur to him that he had forgotten to ask Ying Wushuang about the effects of underwater practice, but through observation, he found that although others weren't moving, they were actually manipulating the halos of heaven in their Qihai.
The water around them vibrated and rippled with each manipulation.
The amount of ripples differed by person.
The less ripples one caused, the stronger energy one had.
Jiang Chen tried to manipulate his halo of heaven. The first time, no ripples had emerged. Only some waves tumbled out. He was embarrassed.
