Zhengyang Gong is divided into three layers, the first layer of qi is to return to yang, that is, to use the thoughts of the 'positive yang qi' scattered throughout the body to introduce the Yintang acupoint between the eyebrows, that is, the meeting of the sun, which can also be called the upper dantian.

According to Wang Lao, he only practiced it when he was fifteen years old, and the Pranya energy absorbed by Xu Qing was the 'positive yang qi' of the root and Miao Hong, and the 'qi' practiced by five division-level old monks who had lived for hundreds of years was not positive yang qi.

According to Wang Lao, practicing the second layer of Zhengyang Gong 'Five Qi Chaoyang' on the dantian can surge tenfold, and the qi can open the stele and crack the stone, and there is a wonderful benefit, the Zhengyang Qi is filled with a golden gun, and it is invincible in a hundred battles, to put it bluntly, this Zhengyang Qi is much better than things like 'Great Buddy' and 'Ah Sanshen Oil'.

However, the second layer of the five qi Chaoyang needs to use the positive yang qi in the dantian to penetrate the 52 single acupoints, 309 double acupoints, and 48 meridian acupoints of the human body, in addition to dredging the 'Ren Pulse' in the center of the front of the body, and the 'Du Pulse' in the center of the back of the body, so that it can be considered practiced.

It took Wang Lao a year just to figure out the location of these acupoints, and another four years to penetrate them with positive yang qi, but he spent most of his time practicing qi, and Xu Qing, who had the help of Prajna relics, didn't seem to have to worry about this, as for identifying acupoints, it shouldn't take much time for him to find them with his right eye that could see through.

In Xu Qing's view, the first two layers of Zhengqigong do not seem to be very difficult, and the third layer of 'Zhengyang Qiankun' is the most difficult to practice, it is said that you have to go to a place of extreme sun to practice for several months, and you have to go to an extremely cold place to practice for several months, and these two places are 'Huozhou' and 'Ice Sea', which happen to be both in the Xinjiang Uygur Autonomous Region.

The Turpan Basin and the Ice Sea Keketuohai, which are known as Huozhou, are in line with the meaning of yin and yang, and the reversal of the universe, and the achievements of practicing Zhengqigong in these two polar regions can be described as a thousand miles in a day.

When mentioning these two polar regions, Xu Qing felt an inexplicable excitement in his heart, and when he had enough time, it seemed really good to travel to these two places.

After listening to the three-layer practice of Zhengyang Gong, it took more than half an hour, and to Xu Qing's surprise, this small voice recorder was still full, it seems that this thing is still a high-end product.

Taking a deep breath, Xu Qing closed his eyes and tried to find the 'positive yang qi' on his body with his mind according to the method that Elder Wang had said, and then channeled them into the upper dantian.

Who knew that when Xu Qing tried to concentrate his mind on the position of his right eye, he was startled, he found that he could clearly 'see' every bifurcated nerve on the lens of the right eyeball, and the entire eyeball formed a three-dimensional hologram in his mind, and the pale golden positive yang qi circulated endlessly in the vitreous, as if it was like a pool of crystal liquid.

Inward-looking? A word flashed in Xu Qing's mind, and with a movement of his mind, he tried to export the positive yang qi contained in the vitreous body along the optic nerve and slowly flow into the Yintang acupoint in the heart of the eyebrows......
