"The five-colored sky is really powerful, the breath is gone, and the body is hidden in the thick fog, silent, invisible, and shadowless, to guard against such a cunning demon clan, it is really difficult to intercept the sect. "Feng Tai and Dao.

"This is not necessary, the battle of immortals and demons is a technique to break the enemy, not an attack. "Yingsheng Dao.

"The art of destroying enemies?" Fairy Ling Yao fell into deep thought.

Qi is a subtle substance with strong vitality, which can stimulate and promote the growth and development of the human body and the physiological functions of various organs and meridians.

Therefore, the growth and development of the human body, the physiological activities of the viscera meridians, the generation and operation of sperm, blood and fluid, etc., all rely on the driving effect of qi.

Yuan Qi can promote the growth, development, reproductive function and functional activities of various organs and tissues of the human body.

If the vitality is insufficient, the driving and stimulating power is weakened, which will lead to the stunting of human growth and development, the decline of reproductive function, or the appearance of premature aging, and at the same time, it can also cause the weakening of the physiological activities of the human organs and meridians, and the life activities are in a state of weakness and weakness.

In addition, physiological activities such as the generation and discharge of essence, the generation and operation of blood, and the generation, distribution and excretion of jin fluid also depend on the promotion and stimulation function of qi to carry out normally.

If the driving effect of qi is weakened, pathological changes such as insufficient metaplasia of essence and its impaired discharge, insufficient production of blood and fluid and sluggish operation and distribution will occur.

In short, the driving effect of qi is manifested in the fact that qi can promote and stimulate all the organs and meridians of the human body to carry out normal physiological activities, and on the other hand, it is manifested in the fact that qi promotes the metabolism of tangible substances such as essence, blood and fluid with its own movement, which shows that the driving effect of qi is the basic guarantee of human life activities.

In order to achieve a harmonious balance between various functional activities within the human body, the regulation of qi is very important.

On the one hand, qi plays the role of promoting, exciting, and rising, and on the other hand, it also plays the role of calming, suppressing, and suppressing.

The former is the effect of the positive component in the qi, and the latter is the effect of the negative component in the qi.

From the point of view of "qi divides yin and yang", the former belongs to the role of yang energy, and the latter belongs to the role of yin energy.

The functional coordination of yin and yang maintains the stability and orderliness of life activities. Yin and yang are rooted in each other, which is one gas, and it is two ears because of the rise and fall.

The stability of human growth and development and reproductive function, the coordination of the functions of the organs and meridians, and the generation and operation of the essence and blood fluid are not only dependent on the promotion and stimulation of yang qi, but also inseparable from the regulatory effects of yin qi such as tranquility and inhibition, which are the result of the opposite effect of the promotion and regulation of yin and yang.

If the tranquility and inhibition of yin qi are weakened, the promotion and stimulation of yang qi are too excessive, and the function of the viscera is deficient and excited, the metabolism of sperm, blood and fluid may be accelerated, and excessive consumption may occur, and symptoms such as sperm loss, sweating, bleeding, irritability, and insomnia can be seen.

The warming effect of qi refers to the fact that qi can produce heat through vaporization, which warms the human body and eliminates cold.

The warming effect of Qi has important physiological significance for the human body.

It can make the human body maintain a relatively constant body temperature, which is helpful for the normal physiological activities of various viscera, meridians, bodies and organs, and is more conducive to the normal discharge, circulation and distribution of sperm and blood fluid, that is, the so-called "walking with temperature, condensation with cold".

The qi that plays the role of warmth is the yang energy of the human body, which is the so-called "yang energy, warm energy." ”

If the yang qi is insufficient and the heat production is too low, it can be seen that the deficiency of cold lesions can be seen, which is manifested as cold and warmth, warmth in the limbs, low body temperature, weakened physiological activities of the viscera, weakened metabolism of sperm, blood and fluid, and sluggish operation.

The qi that plays a cooling role is the yin qi of the human body.

Yin Qi has the characteristics of coolness, softness, and heating. Although the constant body temperature, the stable function of the viscera and the orderly operation and metabolism of the essence, blood and fluid are closely related to the warming effect of yang qi, they are all inseparable from the cooling effect of yin qi, which is the result of the opposition and unity of the warming and cooling effects of yin and yang.

If the cooling effect of yin qi is reduced, hypothermic lesions such as low-grade fever, night sweats, five heart irritability, and thin pulse may occur, and the metabolism of sperm, blood and fluid will be accelerated.

Qi can not only protect the skin surface, defend against the invasion of external evils, but also drive away diseases and evils that invade the human body.

Therefore, the defensive role of qi is very important. If the defense function of qi is normal, then evil qi is not easy to invade.

Therefore, there is a saying that "those who defend qi protect the body for words, divide the flesh warmly, fatten the body, and do not let external evil invade it".

If the defensive effect of qi is low, it is bound to be unable to resist evil, and evil qi is easy to invade and cause disease. ”

When evil qi invades a certain part of the human body, the body's righteous qi will gather in that place and play a role in resisting evil qi and driving away evil spirits.

Therefore, if the defense function of qi is normal, it is not easy for evil qi to invade, or even if evil qi invades, it is not easy to get sick, and even if it occurs, it is easy to cure.

The defense function of Qi determines the occurrence, development and prognosis of disease.

The internal organs and tissues of the human body are relatively independent, but they are full of the substance of qi.

Qi permeates the various organs and tissues of the human body, becoming the intermediary between them.

The mediating role of the body's qi mainly refers to the induction and transmission of information by qi energy to maintain the overall connection of the body.

Qi is the carrier of inductive transmission of information.

All kinds of life information in the human body can be sensed and transmitted through the qi that rises and falls in and out of the body, thus building a close connection between various parts of the human body.

External information is sensed and transmitted to the internal organs, various information of the internal organs is reflected on the body surface, and various information of the internal organs are transmitted to each other, all of which are sensed and transmitted by the invisible qi in the human body as the carrier of information.

For example, the rise and fall of the essence and qi of the internal organs can be reflected in the corresponding tissues and organs on the body surface through the load and conduction of qi, and the internal organs can transmit information through channels such as meridians or trifocal channels, and use qi as the carrier to transmit information, strengthen connections, and maintain coordination.

For example, stimuli and information such as acupuncture, massage or other external treatment methods are also transmitted to the internal organs through the induction of qi, so as to achieve the purpose of regulating the coordination of the body's physiological activities.

Therefore, qi is the carrier of life information and the intermediary between the internal organs, the body and the organs.

The physiological function of Qi boils down to one point, mainly due to the physiological characteristics of Qi that are very energetic and constantly moving.

Qi is the basic subtle substance of the human body, and several physiological functions of qi are inseparable from each other, and they cooperate closely with each other to maintain the normal physiological state of the human body.

The qi of the human body is generated by the innate essence and the essence of the water valley, coupled with the inhaled natural pure qi, through the comprehensive action of the physiological functions of the spleen, stomach, lungs, kidneys and other viscera, and is distributed throughout the body and can be found everywhere.

But specifically, due to the different sources, distribution locations and functional characteristics of the human body, the qi of the human body has its own different names.

Although there are many names for qi, it can be classified from the following three levels.

The qi of the human body, that is, the qi of the whole body, referred to as "popularity" or "qi", is an extremely fine and subtle substance that constitutes the various organs and tissues of the human body and operates throughout the body.

It is generated by the fusion of the qi generated by the innate essence, the qi generated by the essence of the water valley, and the pure qi of the natural world inhaled.

The qi of the human body promotes and regulates the physiological activities of the organs and meridians, the body and organs, promotes and regulates the operation, distribution and metabolism of blood, fluid and essence, and maintains the life process of the human body.

The qi of the body is distributed in different parts of the human body, and it has its own movement form and functional characteristics, so it has different names.

The qi of the human body is relatively different from the evil qi, which is called the righteous qi, and has the functions of defense, anti-evil, regulation, and recovery.

In terms of the source of the human body's qi, the innate essence is the vitality, and the essence of the water valley is the valley qi.

In terms of its distribution position, the qi of the human body is the camp qi when it travels in the veins, and the qi that travels outside the veins is the guard qi; the valley qi and the pure qi of nature gather in the chest is the zongqi; and the qi distributed in the viscera and meridians is called the qi of the viscera and the meridians.

Now that the Qi of the Five-Colored Sky has disappeared, it is not death, which makes Yingsheng, who is a holy immortal, puzzled.

Could it be that the Demon Emperor can control his qi at will?
