As early as when his Spirit Attribute was only in the twenties, Fang Cheng began trying to sense and control the changes in his bodily functions.
Now, with a Spirit Attribute of 43 points, and having mastered Qigong and meditation, he possesses Inner Vision.
He can minutely control each muscle and every blood vessel throughout his body to a degree unimaginable to ordinary people.
It can be said that as long as it's within the tolerable scope of his body, Fang Cheng can freely control the rate of his heartbeat and the fluctuations in his body temperature.
At its lowest, he enters the Fetal Breathing State, with his heart beating only once every few minutes, and his body temperature dropping to around 10℃.
When explosive strength is needed, such as when using the Kirin Arm, his heart behaves like a motor at full power, pumping out enough blood in an instant to ensure a sufficient energy supply.
