On the fifth day of Yan Bugui's return to Mingyuetian after his training, Yan Bugui finally felt that he was about to advance to Bigu.

The so-called 'Bigu', also known as 'broken grain', or there are sayings such as 'but grain', 'rest grain', 'absolute grain', etc., so the technique is often combined with the technique of convincing qi, so it is collectively called "but grain food qi".

The "Chapter of Eating Qi in the Silk Book of the Han Tomb of Mawangdui" is the evidence of the art of eating Qi in the valley in Fang Xiandao. The gods and goddesses are all as light as swallows, with fragrant body and clean skin, and they look like virgins, and they can travel freely in the famous mountains and rivers. If a person wants to become an immortal, he must naturally get rid of filth and take some rare and light incense things. When people eat whole grains, after digestion, they not only turn into fat and gain weight, but also excrete feces and other filth.

Because in the Tao book, there is a saying that "if you want to live forever, your intestines should be pure, and if you want to be immortal, there is no water in your intestines", "those who eat herbs are good at walking and are stupid, those who eat meat are strong and fierce, those who eat grain are wise but not long-lived, and those who eat qi are immortal".

Bigu also became a magic technique for cultivating immortals, and then extended to the Bigu class of cultivating immortals. "Eat the six qi and drink the sun, rinse the sun and contain the morning glow; protect the clarity of the gods, the essence enters and the coarseness is removed", "it is to lead the valley and guide the light body". "It is to learn to open the valley and guide the light body", "I am willing to abandon the affairs of the world, and I want to wander from the red pine nuts!" "The Book of the Later Han Dynasty: The Biography of Fangshu" recorded: "(Hao) Meng Energy contains jujube kernels, and it can be up to five years and ten years without eating. He can also be angry, and his body will not waver, and he will be like a dead man, and he can reach half a year for a hundred days. "

Cao Zhi's "Argument on Taoism" also recorded: "Yu tried to be frugal, desperate for a hundred days, bowed to his bed, and walked freely. Ge Hong's "Hug Puzi Inner Chapter: Miscellaneous Responses" said: "The rest of the people who have seen the valley for three or two years are more than three or two years old, all of them are light and good, they can withstand the cold and summer humidity, and most of them have no fat ears. "

Among them, "there are Feng Sheng, but it has been three years since he swallowed gas and broken the valley, and he has climbed the mountain steeply, and he has been tireless all day long." "Southern History: The Biography of Yinyi" also contains Tao Hongjing's "good method of guiding the valley, self-secluded for more than 40 years, more than 80 years old and magnificent." "

The "History of the North" also contains Wang Yuanzhi, Song Yuquan, Xu Ze, Sun Daomao, etc., all of whom practiced the Bigu Road, and used pine leaves, atractylodes, and poria cocos to self-sufficiency, and obtained the effect of fitness and longevity. In the Tang Dynasty, Gao Dao paid more attention to the way of eating qi in the valley, among which Pan Shizheng, Sun Zhiqiong, Xu Lingfu and other people lived in the mountains to eat pine cones, practiced the art of opening the valley, and were nearly 100 years old.

Yan Bugui still said goodbye to the master like the last time he built the foundation, returned to himself, sat cross-legged in the dormitory, and entered the mulberry green space to cultivate, and after a few hours, he felt a little similar to the feeling of ants crawling in his body when he was building the foundation, but it was a little numb. It's like people who have never eaten spicy food when they first taste the taste of Sichuan peppercorns.

Yan Bugui knew that it was time to go out of the mulberry green space and open the valley, so he got the space. But Yan Bugui still meditated cross-legged to maintain his body motionless, maintaining peace of mind, relaxing his whole body, imagining himself as nothingness, merging in heaven and earth......

About an hour later, the bright moon began to gather dark clouds. The essence of heaven and earth surged towards Yan's place of no return......

Another hour later, the essence of heaven and earth gathered in the bright moon sky began to merge into Yan Bugui's body like a surge. Yan Bugui could clearly feel the whole body aura in his body beginning to change, this change was relatively slight at first, but as time passed, the more intense it became, and at the end it was like boiling water, flowing and boiling in his body. Slowly, a steady stream of spiritual energy entered the body and began to flow to all parts of the body, sour, numb, itchy, painful, all kinds of tastes surged up in Yan Bugui's heart from time to time, as if Yan Bugui had an illusion that his whole body was already full of holes, and spiritual power was the root cause of all this, making up for the modification of these loopholes or deficiencies.

Yan Bugui could also clearly feel that the flow process of these heaven and earth essence qi in the inner body was rapidly changing his body structure.

This process lasted for another 5 hours, and the dark clouds of the bright moon sky dispersed.

At this time, Yan Bugui only felt light, and finally successfully advanced to Bigu. Now Yan Bugui found that in terms of divine consciousness, he could only detect the outside world, but now he can not only do that, but he can also use his divine sense to detect his own body structure. Then Yan Bugui unfolded his divine sense again, and he could actually see all the actions of a grass, a tree, a bird and a beast five or six hundred zhang away outside the house.

Yan Bugui had read a lot of books and materials on cultivating immortals, and he understood that the range that ordinary Bigu monks' divine consciousness could detect was less than 200 zhang, and Yan Bugui himself had just Bigu and had at least three times the detection range of ordinary Bigu monks.

If it were to be strengthened for a few more days, it should be possible to reach about four times the range of the divine consciousness detection of an ordinary Bigu monk. But Yan Bugui will not be arrogant under the master's teaching.

What's more, Yan Bugui also understands that the results of all this are also due to the solid foundation of his own foundation, to put it bluntly, the foundation of the medicinal bath and the guidance of the master Mao Chenghua are closely related, as for his immortal talent, although there are also some factors, it is definitely secondary.

Yan Bugui also used his divine sense to probe his body, and he also had a more detailed understanding of his body structure. Now Yan does not return, and only then does he realize what Bigu is from his own experience.

So Yan Bugui became more and more grateful to his master, master, grandfather and Ming Yuetian of the sect, this gratitude is heartfelt, and Yan Bugui will never be able to forget.

Therefore, Yan Bugui swore in his heart that he would work hard to cultivate and repay them with his own strong growth.

Thinking of this, Yan Bugui couldn't help but think of Grandpa En. Grandpa En has paid so much for himself, but he ended up in such a bleak end.

In the eyes of others, to put it bluntly, I still don't want to live longer, and I can enjoy the pleasures of life more. However, Yan Bugui not only thinks so, in Yan Bugui's eyes, if he can't even take care of his relatives and friends, and even wants his relatives and friends to be implicated, it is to lose the meaning of cultivating immortals.

Therefore, Yan Bugui couldn't help but secretly swear in his heart that he would repay his master well in his lifetime no matter what, and he would also cultivate well to take care of his master and master in the future, and even more so to find a way to save Grandpa En.

After Yan Bugui carefully observed his body thoroughly with his divine sense, he used his divine sense to clean his body again. This function is the ability that will naturally come after entering the valley. After Yan Bugui just opened the valley, his body was full of black filth discharged from his body, and it was extremely smelly.

Yan Bugui has read a lot of books on cultivating immortals, and he knows that he uses his divine sense to cleanse his body. So as soon as I was free, I quickly cleaned my body, and then changed into another set of clothes. As for the smell in the room, Yan Bugui has medicine to get rid of it.

After dealing with his own affairs, Yan Bugui entered the 'Sang Lu' jade pendant space again, and it took three days to consolidate. On the fourth day of Yan Bugui, he began to review the previous spells one by one in the jade pendant space, of course, whether it was offensive or defensive, his strength had generally increased by about 2 times. As for the divine consciousness, it can now be observed in a range of nearly 650 zhang.

What makes Yan Bugui particularly happy this time is that his perception of the 'Cloud and Rain Technique' has also taken a step further. So much so that when he practiced the 'Cloud and Rain Technique' in the Jade Pendant Space, he actually had some fist-sized thunderballs, which could attack some objects under the guidance of lightning. In an attempt, I actually split the leaves of the crown part of a mulberry tree, although the branches were unharmed, but they were also smoked black.

But Yan Bugui did not underestimate this progress, although even a mulberry tree cannot be destroyed now, but as long as the spell has the ability to attack, it is a substantial progress. Yan Bugui believed that in his future cultivation, with his own progress, his attack ability would one day surpass that of the 'Fire Spirit Technique'.

Of course, the most important point is that the 'Fire Spirit Technique' must be a melee attack, while the 'Cloud Rain Technique' is a long-range and large-area attack, and it is still extremely fast, which can basically be said to be undodgable. Therefore, Yan Bugui is very firmly convinced of the master's opinion, and also firmly believes in the power of the 'Cloud and Rain Technique'. Therefore, Yan Bugui made up his mind to practice the 'Cloud and Rain Technique' well.
