Having mastered the basic principles of the Six-Meridian Divine Sword, the following is to consider the transmission and laser firing process of laser in the human body.

"From the general martial arts, the channel for transmission of true qi is meridians, and the light transmission of the Six-Meridian Divine Sword is also like this. The meridians that provide the channel for the true qi operation and are also optical waveguides transmitted by lasers. Otherwise, the laser generated by the powerful pump of the Beiming Divine Tactic has long caused harm to the human body."

"So, it can be assumed that the meridian is actually a waveguide similar to an optical fiber. This can be seen from the usual process of using the Six-Meridian Hongming Sword that this assumption is correct. Since the cutoff frequency of the optical waveguide is zero, it is also suitable for the transmission of general true qi. In transmission, the true qi does not leak generally because the band-bar width of the outer waveguide is large, which forms a barrier to the true qi in transmission. Therefore, except for a small amount of true qi escaping through the tunnel, a large amount of true qi can reach the end point."

"Since the meridians are both the channel for the transmission of true qi and optical waveguides, in this sense, this waveguide is not only the channel for the transmission of light, but also an optical fiber amplifier. While light is transmitted in the meridians, it can also obtain a gain, which greatly increases the output optical power. Therefore, this optical waveguide can be approximated to EDFA (i.e., an erbium-doped fiber amplifier, an active optical device for amplifying signal light). From theoretical calculations, it can be seen that if the gain is larger, the longer the length of the EDFA, the greater the gain obtained."

Thinking of this, Chen Xiao said intimately: "Length, yes, I forgot about this matter. It seems that the internal force needs to be circulated in the meridians longer. I won't be busy for this first, and I will consider this in the end."

"About the authenticity of the Six-Meridian Divine Sword being a biological laser, because the light transmission distance of a true single-mode laser is very long, and the Six-Meridian Divine Sword is a little worse. This has actually been mentioned before. The Six-Meridian Divine Sword is actually a low-power biological laser weapon, which can be seen from the effect of the Six-Meridian Divine Sword."

"However, there are still many problems that need to be solved urgently, such as excessive transmission loss and non-basic mode lasers, which greatly affect the power of the Six-Meridian Divine Sword. Since general pumps are formed by changing the distribution of magnetic fields, it is difficult to obtain a larger pump. Even for the Beiming Divine Sword, the slight difference in the distribution of the potential field and the conditions of the resonant cavity will lead to a significant decrease in the output power. However, we have reason to believe that through theoretical calculations, we can make the true aura field of the Beiming Divine Sword fully meet the conditions of the resonant cavity. At this time, the power of the Six-Meridian Divine Sword will be several times higher."

"In addition, from the six-mere magic swords of Duan Dali, they all come out from their fingers. It is obvious that Einstein's laser theory has not appeared in this world. I remember that the theory I have studied before. It is roughly said that in the atoms that make up matter, there are different numbers of particles (electrons) distributed at different energy levels. Particles at high energy levels will jump from high energy levels to (transition) to low energy levels. At this time, light of the same properties as the light that excites it will be emitted, and in a certain state, a weak light can excite a strong light. This is called 'light amplification of stimulated radiation', referred to as laser."

"So it is certain that Dali Duan's understanding of the laser principle is not very deep, so the output lasers are not fundamental mode lasers. From the laser principle, we can see that the laser spot area of ​​high-order modes is large, but the power density, intensity, etc. are worse than that of the basic mode laser. Therefore, the Six-Meridian Divine Sword still has a lot of room for improvement."

"In addition, the loss of air to laser is very large. Due to the effects of scattering, absorption, etc., the loss of air to laser is very large. Moreover, judging from the previous results of Duan Yu using the Six-Meridian Divine Sword, the output laser wavelength of his Six-Meridian Divine Sword is very likely to be in the ultraviolet band, not within the range of the smallest loss coefficient of air, and coupled with non-basic mode laser, Duan Yu's Six-Meridian Divine Sword is much less powerful than the theoretical value."

"So it can be imagined that the areas where these six-mechanical divine swords need to be improved are basically choosing the appropriate wavelength, realizing pure fundamental mode output, reducing output loss and threshold true air density, etc.."

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

"It's simple to reduce the loss. Completely close the six meridians of the hand, and the acupoints above become the node of internal force acceleration. Speaking of which, my innate Wujigong is really similar to these six meridian lasers... Why didn't I find pinching before?"

"Well, what's left is to try to lengthen the circulation of internal force in the body. It seems that the six meridians of the hand cannot be in the circulation. Then the six meridians of the foot and the eight meridians are extraordinary meridians. This happens to be within the range of laser base charging. Hehe, then the next thing is how to connect these fourteen meridians."

"The connection between the human meridians is that the sun is against the sun, Yangming is against Yangming, Shaoyang is against Shaoyang, Jueyin is against Jueyin, Taiyin is against Taiyin, Shaoyin is against Shaoyin, Shaoyin is against Shaoyin, which is very regular."

"In order, the twelve meridians are the first hand Taiyin lung meridian, the second hand Yangming large intestine meridian, the third foot Yangming stomach meridian, the fourth foot Taiyin spleen meridian, the later hand Shaoyin heart meridian, the hand Taiyang small intestine meridian, the foot Taiyang bladder meridian, the foot Shaoyin kidney meridian, the hand Jueyin pericardial meridian, the hand Shaoyang triple burner meridian, and the last is the foot Shaoyang gallbladder meridian, the foot Jueyin liver meridian."

"If the six meridians of the hand are removed, the remaining six meridians of the foot, including the foot Taiyang bladder meridian Ren water, the foot Shaoyin kidney meridian Gui water, the foot Shaoyang gallbladder meridian Jia wood, the foot Jueyin liver meridian Yi wood, the foot Yangming stomach meridian Wu earth, and the foot Taiyin spleen meridian Ji earth."

"The three yins of the hand move from the chest to the hand; the three yangs of the hand move from the head to the hand; the three yangs of the foot move from the head to the foot; the three yins of the foot move from the foot to the abdomen."

"The Yin meridian and the Yang meridian intersect at the limbs; the Yin meridian and the Yin meridian intersect at the chest and abdomen; the Yang meridian and the Yang meridian intersect at the head and face."

"The Yin meridian is distributed on the inner side of the limbs and the chest and abdomen; the Yang meridian is distributed on the outer side of the limbs and the head and face trunk."

"Yangming, Taiyin is in front; Shaoyang, Jueyin is in the middle (side); Taiyang, Shaoyin is behind; Jueyin meridian of the foot is in the lower half of the calf and the back of the foot before Taiyin meridian of the foot is a special thing."

"Those are obviously not enough. Well, let's calculate the eight extraordinary scriptures."

"The Du meridian meets the six yangs of the hands and feet at Dazhui, and meets the Yangwei meridian at Yamen and Fengfu; it starts from the perineum and connects to the Chengji point. It is the sea of ​​the yang meridian. The Ren meridian meets the Sanyin meridian at Zhongji, Guanyuan, and Yinwei meridian meets the Tiantu and Lianquan; it meets the Chong meridian at Yinjiao. Although it does not directly intersect with the hand and Yin meridian, it can also ventilate. The sea of ​​the yin meridian originates from the perineum to the vagina."

"The Chong meridian and the foot Shaoyin are connected to the top and are important for the body. They receive the meridians of the stomach and kidney meridians, so they are called the sea of ​​the twelve meridians. At the same time, the foot Yangming meridian also controls blood, so it also becomes the sea of ​​blood. The belt meridian, which binds the upright meridians of the whole body to form a belt."
