The thickness of the cover and the bottom is not the same, so Lin Mu felt a little puzzled, because he read the Shennong herbal Scripture and found that the thickness of each page of the book is uniform, and there is no such uneven phenomenon.

As the most important cover of the Sutra, the uneven thickness of the cover and the bottom made him curious. He put the Sutra upside down in his hand and looked at it carefully.

After careful examination, he suddenly found something different. The reason why the thickness of the bottom is different is that two thinner layers of paper are used to bond the bottom. It seems that something is wrapped in the middle.

Lin Mu, who was curious in his heart, immediately pulled out Qiu Hong's sword, which was as thin as a cicada's wing on his waist. With a slight shake of the tip of the sword, he picked out the bottom page of the two bonded pages in an instant. Then he carefully tore open the crack, and found a piece of folded transparent paper in it.

Carefully took out the paper, and then he spread out the paper. It was a piece of paper about one meter long. After the paper was opened, there was no sign of folding in the middle. This scene made him praise it softly.

The paper is full of small characters on the head of the flies. Even if Lin Mu's eyes are like electricity, he carefully distinguishes for a while before he finds out where the head of these characters is.

At that time, he said that the medicine King Scripture practiced by Shennong family was hidden in Shennong Baicao Scripture, so the Ao family spared no effort to collect the fragments of Shennong Baicao Scripture, and even found Wang Zhichuan's hometown in Changsha.

I didn't expect that this medicine King Scripture was really hidden in Shennong's herbal Scripture. It's just that it's not the incomplete version of the Scripture that you family put out to hide people's eyes and ears. It's in the complete version of the Scripture that Shennong left behind. It's estimated that Shennong didn't tell his descendants when he hid this medicine King Scripture, otherwise you family would not be what they are today.

With the help of the energy-saving lamp beside him, Lin Mu stepped forward and carefully looked at the contents of the skills recorded in the book of medicine king. He wanted to see the magic of the martial arts that made Shennong a peerless master.

Strictly speaking, this martial art is not a martial art created by Shennong after his success, but a martial art that he started to create at the place where he practiced. Only when he perfected this martial art, his strength has reached the level of peerless master.

The more he looked down on it, the more he admired Shennong. He actually mixed countless kinds of medicinal materials together and thoroughly refined the extremely complex medicinal properties when taking them together, so as to cultivate a special genuine Qi called yaowangqi.

Once this kind of true Qi is cultivated, it can be transformed directly by heart. It can be transformed into either benign true Qi for curing diseases and saving people, or toxic true Qi for killing people instantly. The transformation is only in a moment. This is also the secret of Shennong's taking human life without moving his face.

When you contact Shennong, who is in the highest realm of the medicine King Sutra, you can make colorless and tasteless poisonous Qi spread all around you in silence. People around you have already been infected with this kind of poisonous Qi even when they are not aware of it.

Once it's used, there's no antidote in the world. Even Shennong himself can't produce this antidote, because it's a combination of countless kinds of herbs. Only his own genuine Qi can detoxify, and other methods are ineffective.

At that time, with the help of the medicine King Scripture, Shennong's reputation was much more powerful than that of other peerless experts. If it wasn't for Shennong's mellow nature and didn't like to kill, I'm afraid people in the Wulin would have turned pale.

However, the cultivation of this medicine King Sutra is also very dangerous. First of all, you need to thoroughly understand the Shennong herbal Sutra, and then it is possible to cultivate successfully, condense the real medicine king Qi in your body. Otherwise, if you make a mistake, you may go crazy, or you may die on the spot, and there is no time for rescue.

Once out of control, all kinds of drug king Qi with chaotic properties can be compared with the most toxic poison in the world. Moreover, it will poison and die in an instant. There is no chance to take antidote.

After carefully reading the king of medicine Scripture, Lin Mu collected the thin transparent paper and put it in the gap of the last page of the king of medicine Scripture. Then he put the whole Scripture into the ring. The cultivation of the king of medicine Scripture was so dangerous that he had to consider whether to cultivate Zhou Shiyun.

After calming down, he settled down and entered the state of regulating breath again. He completely emptied his body and mind. He constantly recalled the outline of the northern underworld divine skill and the points for attention in cultivation. After a while, he began to prepare for the first step of cultivation.

After breathing for a full hour, Lin Mu completely calmed down. The liquid real gas cyclone in the Dantian suddenly began to rotate in reverse direction. This sudden change suddenly caused a sharp pain from the Dantian. Even Lin Mu could not help but snort, and a thin layer of sweat appeared on his forehead.

However, this process must be experienced in the process of dispersing the true Qi, because it is to disperse the true Qi for the cultivation of Beiming divine skill. Therefore, the true Qi can not be directly and thoroughly dispersed. Generally, the true Qi will naturally disperse as long as the people who are dispersing the true Qi are bound by the Dantian.

But this kind of dispersing process can't carry out the cultivation of Beiming divine skill. Although this kind of dispersing skill has no pain, it's not suitable for the current situation. Therefore, Lin Mu can't choose this way. He can only carry out dispersing skill according to the way recorded above.

With the pain in Dantian, Lin Mu insisted on reversing the true Qi cyclone. In a short time, the cyclone stopped, and then began to reverse. Then the pure and incomparable true Qi began to escape from Dantian, and slowly filled the whole body. The process of dispersing power lasted nearly two hours, and the cyclone in Dantian was completely dissipated. Then the last lax Qi escaped from Dantian, and it took more than ten minutes. At this point, dispersing power is the complete end. The first step of the process has been completed. The rest is to use these genuine Qi to form a unique cycle of Beiming divine skill in the body, to open up 108 acupoints that need to be used in the body. These acupoints and the cycle of Beiming divine skill form a mysterious echo, and then the final Beiming genuine Qi will be formed. He closed his eyes and adjusted his breath for half an hour to recover his lost mind. Lin Mu started the second step to form the cycle of true Qi. This step is relatively simple for a man with strong soul power, but it took less than 20 minutes to succeed. This circulation of Qi circulates in the body for a big week. Then Lin Mu starts to use this circulation to communicate with the 108 big acupoints that need to be used in the body. These acupoints are located all over the body, and even interact with the stars when they are connected. The process of connecting these acupoints is relatively long. The main reason is that the sequence of connecting each acupoint is strict. When connecting a acupoint, the circulation of true Qi in the body needs to be introduced into that acupoint for circulation. Only when the circulation of true Qi is stable can the next acupoint be connected. Even if Lin Mu's control power was so strong and his mind power was so abundant, he almost failed several times in the third step. If his mind power had not been strong enough, he would have failed in the last moment. But there is only one end to failure, that is, true dispersion. All the true Qi in the body is wasted. It's a long waiting time to practice again from the beginning and return the lost true Qi in the body. Two days later, the sweating Lin Mu slowly opened his eyes, and the 108 big acupoints in his body were finally thoroughly penetrated by the circulation of true Qi, forming a very complex formation in his body. The 108 big acupoints are the foundation of this formation“ Whoo! The most miserable stage has finally passed. Now as long as the circulation of true Qi in the body is transformed into the true Qi of the northern underworld after that big change, and then the true Qi is recovered into the Dantian, and then the true Qi is condensed into a cyclone again, the cultivation of the divine skill of the northern underworld can be regarded as a real success. " After thinking for a while, Lin Mu decided on the following cultivation plan, and then took a full day off to completely recover his lost mind before he closed his eyes again and entered the cultivation state. The process of transforming Qi is relatively smooth. It just takes a little longer. Compared with the previous process, it is not dangerous at all. It's all water grinding. It took Lin Mu another three days. It took him about a week to really practice the northern underworld magic skill. There was a real Qi cyclone in Dantian, but at this time, the color of the real Qi cyclone had turned into a strange light gray. Through the internal view, Lin Mu carefully looked at the light gray cyclone slowly rotating in Dantian. A very strange wave came out of the cyclone. For a moment, he was not sure whether the northern underworld magic was so magical. However, as like as two peas in the north, the real Qi of the refined spirit is exactly the same as that recorded in the northern gods. It seems that the practice is successful. In this way, Lin Mu no longer entangled these details. After a little tidying up, he was in a flash and the human had disappeared from the cave. I've been practicing in the cave for more than a week. The martial arts contest of the Lu family is over. The people of Jingchen temple should come back. Now that they've all come to Mount Emei, I'll take them around to see if they're back. By the way, I'll see if ye Zixi is back together.
