The Yan family's mental method is called "Five Hearts to Supplement Heaven", and after the aura enters the body, it is divided into two cycles: internal and external. On the outer circulation, it enters from the Baihui acupoint, the main goes to the Ren vein, to the Tiantu acupoint, and then divides into the Sanyang meridian and then converges at the Laogong acupoint; The next is from the Yongquan acupoint and enters, walks the three yin meridians into the Du vein, all the way to the Tao Dao acupoint and divides into the three yang meridians, and finally converges in the Laogong acupoint.

The internal circulation is from the Laogong acupoint to the three yin meridians into the Ren vein, and then from the Jizhong acupoint through the purple palace into the dantian.

The route connecting the inner and outer circulation is to go from the dantian to the Ren vein, part of which is divided into the Zusanyang meridian and then converges at the Yongquan acupoint, and the other part enters the Du vein from the perineum acupoint and returns to the Baihui acupoint.

In this way, the internal and external circulation is completed, commonly known as the Great Zhoutian.

Therefore, whether it is practicing martial arts or cultivating the truth, it is very important to open up the two veins of Ren and Du, which is related to whether or not you can complete the cycle of the Great Zhou Tian Cycle to realize the cycle of internal force or spiritual power.

Yan Wo simulated the route in his mind dozens of times before he began to try to gather spirit condensation. Before gathering the spirit and condensing the qi, it is natural to first introduce the spirit into the body, which is not enough to simply introduce the spirit into the body, so the little spiritual energy in the air is not enough at all, and at this time, the spirit beads issued by the family must be used.

Because of the particularity of the Yan family's mental method, it is also superfluous to hold the beads in the palm of the hand, so Yan Wo only put one in front of him, one on the left side of the body, one on the right side.

The aura of the spirit beads will automatically leak out, and at this time, you only need to guide them into the body step by step.

The aura flows from the Baihui acupoint on the top of Yan Wo's head and the spring acupoint on the soles of the feet, and then Yan Wo silently recites the mental method to pull the aura to carry out the external circulation operation, this step can be described as a single heart and three uses, and it is really troublesome to guide the three routes. However, the biggest obstacle is to open up the meridians, because the aura is the first route, so the meridians are not smooth. But as long as this process is over, the operation of the aura in the future will be much easier, and they will automatically form a cycle without even deliberately guiding.

At the same time, this process is accompanied by the washing of the meridians and the removal of the marrow, and some toxins will be discharged from the opening of the meridians, which is more conducive to cultivation.

The blockage of Yan's meridians is not serious, because he is still young, there are not many toxins in his body, and the young man's meridians are strong, and the process of opening up is much smoother. Otherwise, if you change to an elderly person with weak meridians, maybe the washing of the meridians and marrow is not completed, and the meridians will burst first.

The outer circulation was quickly completed, and the next step was the internal circulation, changing the soup without changing the medicine, or the familiar formula, or the same routine.

It's just that there is a big hurdle here, that is, the connection between the internal and external circulation-opening up the two veins of Ren and Du. There are two places that need to be opened, one in the Baihui acupoint and one in the perineal acupoint.

The Baihui acupoint is on the top of the head at the heavenly spirit cover, and the perineal acupoint is ...... Ahem, it's the chrysanthemum there.

The former is related to whether the aura can enter the Ren pulse again, and the latter is related to whether the aura can enter the Du pulse and return to the Baihui acupoint.

After the completion of the internal and external circulation, Yan Wo encountered a bottleneck, and only by breaking through this bottleneck could he complete the first Great Zhou Tian, which was related to whether he could successfully reach the first level of Qi training.

The Baihui acupoint and the perineum acupoint continue to have aura convergence, and the two places gradually heat up and even become hot.

Yan Wo's face was painful, but he gritted his teeth and tried to hit the bottleneck.

At this time, the advantages of the single spirit root are revealed, and its absorption of spiritual energy is fast, which ensures that Yan Wo is full of stamina and continuous supply, providing a large amount of "living power" for breaking through the bottleneck.

Finally, Yan Wo successfully opened up the second pulse of Ren Du before dinner, and the aura in his body achieved the first Great Zhou Tian cycle, and then there was no need to be so difficult, and the aura would automatically operate. It's just that without deliberate guidance, the operation will be very slow, and it may take a day in a big week.

Yan Wo was covered in stinky sweat, and his body was sticky and stained.

He hurriedly got up, put away the four spirit beads that had not been used up, and then rushed into the bathroom to take a bath.
