() Human sleep has always been a very magical state. Even ordinary society can be divided into light sleep, deep sleep, and dreamless deep sleep. In some Taoist theories, there are states such as entering concentration, fetal breath, the unity of heaven and man, etc. In fact, it is also a state of sleep, but it is obviously not something ordinary humans can achieve. It requires long-term cultivation and certain opportunities. Therefore, in ancient books, this state is described as a very lucky accident. And those so-called epiphanies are the key to some people's breakthroughs.
Bai Yi put the five people into a deep dreamless sleep, which can be said to be the best sleeping state that ordinary humans can achieve. According to outside scientific research, it only takes one hour a day for a person to regain all his energy in dreamless deep sleep, and the quality is far higher than sleeping for more than ten hours a day.
Under Bai Yi's hypnosis, the bodies and souls of these five people were rapidly harmonizing. This was a kind of self-adjustment, a more advanced adjustment than simple physical and endocrine adjustment. What Bai Yi did was just to provide them with a suitable environment, but this environment was the most difficult for everyone to achieve.
