"So, how can the brain be changed?"
Tang Zichen, like an untiring scholar, wanted to know the answer.
After all, she had senses like "the mantis feels the approach of autumn without the wind blowing," enabling her to sense imminent danger in the unseen and avoid it in advance.
It was truly: Unseen and unheard, sense the danger and avoid it.
She guessed that this had something to do with her spiritual cultivation, but as for explaining how, she was currently unable, attributing it only to a feature of martial arts practiced to the ultimate level.
"I am also pondering on that,"
Sun Shisheng said, "It's not yet perfected, but I roughly have a direction."
"Could you elaborate?" asked Tang Zichen.
"Of course," nodded Sun Shisheng, "First and foremost is sleep, deep sleep."
Tang Zichen slowly nodded.
She was somewhat familiar with deep sleep.
