Now that we have mastered the basic principles of the Six-Vein Divine Sword, the following is to consider the transmission and lasing process of the laser in the human body.

"From the perspective of general martial arts, the channel for the transmission of true qi is the meridians, and the light transmission of the six-vein divine sword is also like this, the meridians that provide the channel for the operation of true qi are also the optical waveguides for laser transmission, otherwise, the laser generated by the powerful pump of the Northern Pluto Divine Gong has already caused harm to the human body."

"So, it can be assumed that the meridian is actually a waveguide similar to a fiber optic fiber. This can be seen from the usual use of the Six-Vein Rainbow Sword, and this assumption is correct. Since the cut-off frequency of the optical waveguide is zero, it is also suitable for the transmission of general true gas, and the general true gas does not leak in the transmission, because the bandgap of the outer waveguide is large, which constitutes a potential barrier to the true gas in the transmission, so except for a small amount of true gas escaping through tunneling, a large amount of true gas can reach the end point. ”

"Since the meridian is both a channel for the transmission of true qi and an optical waveguide, in this sense, this section of the waveguide is not only a channel for optical transmission, but also a fiber optic amplifier. While the light is transmitted in the meridians, it can also obtain gain, which greatly improves the output optical power, so this section of optical waveguide can be approximated into EDFA (that is, erbium-doped fiber amplifier, which is an active optical device for signal optical amplification), and it can be seen from theoretical calculations that if the gain is larger, the longer the length of EDFA, the greater the gain obtained. ”

Thinking of this, Chen Xiao said secretly: "Length, well, forget about this matter, it seems that the internal force needs to circulate a little longer in the meridians." I'm not busy with this one for now, and I'll think about it at the end. ”

"About the authenticity of the six-vein divine sword is a biological laser. Because the light transmission distance of a real single-mode laser is very long, and the six-vein divine sword is a little worse, which has actually been mentioned earlier. The Six-Vein Divine Sword is actually a low-power biological laser weapon, which can be seen from the effect of the Six-Vein Divine Sword. ”

"It's just that there are still many problems that need to be solved urgently in the biological laser of the Six-Vein Divine Sword, such as excessive transmission loss and non-fundamental mode lasing, which greatly affects the power of the Six-Vein Divine Sword. Since a general pump is formed by changing the distribution of the magnetic field, it is difficult to obtain a larger pump. Even if it's the Northern Spiritual Skill. Because of the small difference in the potential field distribution and resonator conditions, the output power will also be greatly reduced, but we have reason to believe that through theoretical calculations. We can make the true aura of the Northern Spiritual Skill fully conform to the conditions of the resonant cavity. The six-vein divine sword at this time. The power will increase several times. ”

"In addition, judging from the Dali Duan Clan's six-vein divine sword, it is all issued from the fingers. Obviously, Einstein's laser theory has not yet appeared in this world, and that set of theories has been studied before, which roughly means that in the atoms that make up matter, there are different numbers of particles (electrons) distributed at different energy levels, and the particles at the higher energy level are excited by a certain photon, and will jump from the high energy level to the lower energy level, and then the light with the same properties as the light that excites it will be emitted, and in a certain state, there can be a phenomenon that a weak light excites a strong light. This is called 'light amplification by stimulated radiation', or laser for short. ”

"So it is certain that Dali Duan's understanding of the laser principle is not very deep, so the output of the laser is not the fundamental mode lasing, from the laser principle, it can be seen that the laser spot area of the high-order mode is large, but the power density, intensity, etc., are worse than the basic mode laser, therefore, the six-vein divine sword still has a lot of room for improvement."

"In addition, the loss of air to the laser is very large, due to scattering, absorption, etc., the loss of air to the laser is very large, and from the results of Duan Yu's previous use of the six-vein divine sword, the output laser wavelength of his six-vein divine sword is very likely to be in the ultraviolet band, not within the range of the smallest loss coefficient of air, plus non-fundamental mode lasing, so Duan Yu's six-vein divine sword, the power is far lower than the theoretical value."

"So it is conceivable that the improvement of this six-vein divine sword is probably to choose the right wavelength, realize the pure fundamental mode output, reduce the output loss and threshold true gas density, and so on."

Chen Xiao stretched out his finger and slowly drew on the ground: "These things are actually simpler, that is, the principle of laser generation is used when the internal force is walking in the body to reduce the loss. ”

"It's simple to reduce the loss, completely close the six veins of the hand, and the acupoints above become the internal force acceleration nodes...... Why didn't I find a pinch before? ”

"Well, the rest is to try to lengthen the circulation of internal force in the body, it seems that the six veins of the hand cannot be in the circulation, then it is the six veins of the foot and the eight veins of the strange meridians, so they all happen to belong to the scope of the laser base charging class, hehe, then the next thing is how to connect these fourteen meridians."

"The connection of the meridians of the human body, sun to sun, yang to yang, less yang to less yang, yin to yin, too yin to too yin, less yin to less yin, is very regular."

"In order, the twelve major meridians are the first hand Taiyin Lung Meridian, the second hand Yang Ming Large Intestine Meridian, the third Foot Yang Ming Stomach Meridian and the fourth foot Taiyin Spleen Meridian, and then the Hand Shao Yin Heart Meridian, the Hand Sun Small Intestine Meridian, the Foot Sun Bladder Meridian, the Foot Shao Yin Kidney Meridian, the Hand Shao Yin Pericardial Meridian, the Hand Shao Yang Sanjiao Meridian, and finally the Foot Shao Yang Gall Meridian, the Foot Shao Yang Liver Meridian."

"If the six veins of the hand are removed, the remaining six veins of the foot, of which the foot sun bladder meridian is non water, and the foot is less yin and kidney meridian dehydration. The foot is less yang gallbladder through Jiamu, and the foot is yin and liver through Yimu. The foot yang and the stomach pass through the earth, and the foot is too yin and the spleen passes through the soil. ”

"The three yin of the hand, from the chest to the hand; The three yangs of the hand, from the hand to the head; The three yangs of the foot, go from the beginning to the foot; The three yin of the foot, from the foot to the abdomen. ”

"The Yin and Yang meridians meet in the limbs; Yin meridian and Yin meridian, at the junction of the chest and abdomen; The yang meridian and the yang meridian are connected on the head and face. ”

"The yin meridians are distributed on the inner sides of the limbs and the chest and abdomen; The yang meridian is distributed on the outside of the limbs and the head, face, and trunk. ”

"Yang Ming and Taiyin are in front; Less yang and yin in the middle (side); The sun and the shade are behind; The foot syncope yin meridian is a special one in the lower half of the calf and the dorsum of the foot before the foot Taiyin meridian. ”

"It's not enough to be obvious. Well, let's calculate the Eight Great Wonders. ”

"Du Mai, and the six yangs of the hands and feet intersect in the big vertebrae, and the yang veins meet in the dumb door and the wind mansion; It originates from the perineum and connects with the Ren pulse in the pulp acupoint. It is the sea of yang veins. Ren pulse, and the three yin meet in the middle pole, Guan Yuan, and the yin dimension intersection in Tiantu, Lianquan; and the pulse intersect in the yin. Although it does not directly intersect with the Yin meridian of the hand, it can also be ventilated. The Sea of Yin Veins. Begins in front of the perineum and pussy. ”

"Rushing the pulse, and enough to go straight up, is very important. Accept the pulse qi of the stomach and kidney meridians, so it is called the sea of the twelve meridians. At the same time, the Zuyang Ming Sutra is also the main blood, so it also becomes a sea of blood. The belt veins bind the upright meridians of the whole body into a belt. ”

"Yang Wei pulse is closely related to the three yangs of hands and feet. Yin dimensional vein, the main body. Yang stilt vein, the main body of the left and right yang. Yin seesaw veins, the yin of the main body left and right. (To be continued......)
