The bookshelves are very high. The bookshelves in the sixth row are more than two meters long. They are all luxurious bookshelves.

However, Lin Mu couldn't get out of his reach. He didn't even go to the ladder to get the book. He directly reached for the book designated by master Lin and sucked it out of the air. A force of suction suddenly came out of his palm and directly sucked the book with the crimson cover into his hand.

As soon as the book was in hand, Lin Mu immediately realized that it was different. First of all, it was different from ordinary books. It could not be opened. The page on the side was just a decoration. It was a complete physical design. It was very heavy to hold.

Mr. Lin took the book from Mr. Lin Mu, then gently scratched on the spine of the book, and a small screen appeared there. Then he pressed his thumb on the small screen, and a fingerprint immediately appeared on the screen.

"Drop! Drop

After two soft rings, the cover of the book suddenly bounced up. Then Mr. Lin opened the cover and revealed a small groove inside. A dark purple fragment was lying quietly in the groove, covered with mysterious bright lines.

"Is this Lei Shi?"

Lin Mu carefully looked at the Leishi lying in the groove and asked curiously.

"Yes, this is the legendary Lei Shi. People who don't know this history don't know what it is. Although I don't practice martial arts, because my family is in charge of collecting antiques, I read a wide range of books. I've also seen this record by accident."

Master Lin nodded, then took out the Thunder Stone and handed it to the palm of Lin Mu's hand. "Although I don't know how much you have practiced, I always think your martial arts are very powerful. Take this Thunder Stone and remember that you can't swallow it before you arrive at the congenital environment!"

"Don't worry, I know what to do."

Lin Mu took over the Thunder Stone and nodded calmly. He knew that master Lin also cared about him. After all, once something happened to him, the Lin family would basically collapse. It's no use relying on master Lin alone. After all, he is too old to show up and run the family business.

As soon as Lei Shi reached the palm of his hand, with his innate sensitivity, he immediately felt the great power of thunder coming from it. This power even made his mind tremble completely, and his doubts suddenly came to his mind.

You should know that his mental strength is much stronger than that of ordinary people. Even people with higher martial arts level can never be more powerful than him, because his soul is the soul of a master of truth cultivation in the period of disaster.

Even though the soul has been greatly weakened after the natural disaster, it is still not comparable to those who practice martial arts. After the leap of Yuanying period, distraction period, out of body period and fitness period, the soul power of Lin Mu has already made a qualitative leap, which can not be made up in quantity.

But even so, the power revealed by the Thunder Stone in the palm of his hand shakes his mind. It can be seen that the power contained in it is incredible.

"Sir, I feel some magic in this Thunder Stone. Now I need to understand it here."

Lin Mu's eyes lit up for a while. What could shake his mind was absolutely a good baby!

"Well, you can understand quietly here. I will tell people not to disturb you."

Master Lin nodded. He knew that martial arts practitioners like Lin Mu sometimes had a sudden epiphany and gained a lot. He immediately waved his hand and asked Fu Bo to push him down. Then he closed the door of the stairwell on the fifth floor and told others not to disturb Lin Mu.

After they left, Lin Mu didn't pay attention to it either. He just sat cross legged on the ground and put the Thunder Stone in his hands. Then he closed his eyes and adjusted his state to the best. A wisp of consciousness came out carefully and wound it on the Thunder Stone gently.

It's just a slight to extreme action. There is a flash of light on the surface of Lei Shi. Lin Mu hums directly. A wisp of blood immediately overflows from his nose. The state of being just settled is also broken, and his eyes suddenly open.

"It can directly break the power of the soul. It's really a good baby!"

The injury is not very serious. Compared with the injury, the discovery just now makes Lin Mu more excited.

The energy level of soul power is very high, which belongs to the high-level energy category in the energy of the universe, so ordinary objects can not detect the soul power at all, and only the energy of the same level can react with the soul power again.

The power of thunder and lightning belongs to the energy that exists at the same level as the power of soul, so the power of thunder contained in this Thunder Stone, when the power of soul is entangled by Lin Mu's consciousness, directly sends out some slight power, which directly shocks the power of soul.

After holding the stone in his hand for a while, Lin Mu finally gave up his plan to swallow it. Although it is recorded in ancient books, the strength of the experts in the congenital realm is also very strong.

The experts who have just entered the congenital realm are also in the category of congenital realm, and the experts at the top of congenital realm are also in the category of congenital realm. However, their strength is very different, and they can't whisper in the same day. Therefore, Lin Mu thinks it's better to be cautious.

After all, things are in his hands. When his strength is almost increased, he can always solve the secrets of Leishi. Don't worry for a moment. There are many things for him now. If there is any accident caused by swallowing Leishi at this time, it's a very bad thing. Now that he has made a decision, he doesn't hesitate to put Lei Shi in the ring. Then he begins to meditate quietly. Now that he has come, he will stay here for a night and quietly understand what he has gained in the Lu family. The biggest harvest of this trip to the Lu family is the Beiming divine skill. The power of the complete version of Beiming divine skill is self-evident. It's very powerful. If you can practice it successfully, it will be much faster than Lin Mu's current practice speed. After all, even if he has the help of the ring, he can refine the aura of heaven and earth, and also can quickly absorb the aura of the surrounding weather, but the cultivation environment of the earth itself is very poor, the aura of heaven and earth is very thin, and the cultivation speed is naturally not fast. However, once the cultivation of Beiming divine skill is successful and can devour the energy cultivated by others, it means that there are countless people helping him to cultivate. He only needs to absorb the power cultivated by these people. Although it's inhumane to do so, Lin Mu didn't kill innocent people indiscriminately. Now that the evil cult is back in the world, it's a matter of great merit to capture the people of the evil cult and absorb the power in their bodies, so that these heretics will never be able to commit crimes. However, the most hesitant thing for Lin Mu is the method recorded in the skill. He needs to go through a process of dispersing the skill. Only by dispersing the true Qi in the body completely and expelling the elixir field completely, can the whole body's true Qi be slowly transformed into the true Qi of the northern underworld. This process depends on the individual's cultivation, and the speed is not the same. However, once the cultivation fails, this will be the real dispersing skill. At that time, not only the cultivation of northern Ming divine skill will fail, but also the original power will disappear. Because it is active dispersing, it is impossible to recover these power. It's difficult for countless people who want to practice Beiming divine skill. If they don't reach the congenital state, they can't practice Beiming divine skill at all. But once they reach the congenital state, their strength is already very strong. It's too risky for them to change to another martial art at the risk of doing some exercises. Lin Mu is now in such a hesitation. There is no doubt that he is powerful now. As long as he doesn't meet those old monsters who have practiced for a long time on earth, he can basically walk horizontally. But this cultivation is far from enough for him to reach the golden elixir stage. After thinking about it for a long time, Lin Mu repeatedly realized the outline of Beiming divine skill in his mind. He was constantly struggling in his heart whether he wanted to practice this martial skill now. If he failed to practice it now, it would be faster to practice it again. If it really takes a long time, his skill will be more profound at that time. Once his cultivation goes wrong, it will take him a longer time to recover his lost skill. There are more opponents at that time, so I'm afraid he won't be given this opportunity. Thinking of this, Lin Mu is quick to make a decision. He has started to practice Beiming divine skill recently. However, when practicing this martial skill, he needs an absolutely hidden place and can't be disturbed by anyone, so it's definitely not possible to be in Donghai. He needs to find another place. After thinking about it, he suddenly thought of a place, that is, the hand-painted map you Yongwei gave him, where the secret of you family's inheritance for more than a thousand years was hidden. Shennong's most important book Shennong Baicao Jing was very hidden, but it was a suitable place for seclusion. Thinking of this, Lin Mu immediately took out the hand drawn map in the ring and carefully looked at the route above. The mountain depicts the heavy terrain and trend of Mount Emei. Comparing with the map of Mount Emei in his memory, he soon found the contrast. Quietly looking at the map in his hand, he has made up his mind to set out for Mount Emei early tomorrow morning, ready to find this book of Shennong's hundred herbs, which has been hidden for thousands of years.
