This book that describes the energy ducts of the human body is called "Human Body and Energy Science", which seems very similar to the acupuncture theory learned by Li Zhong in his previous life.

It seems that it has been a long history, and the paper is so yellow that it turns yellow. When Li Zhong found it, it was covered with dust. It seems that almost no one has read this book.

Looking at the complex energy pipeline maps in this book, Li Zhong felt like he was reading the secrets of ancient immortal cultivation, although Li Zhong knew in his previous life that this did not exist.

Because in his previous life, after Li Zhong practiced martial arts to the highest level, he saw countless acupoints in his body and could clearly know that there were no energy channels in the human body.

Those countless acupoints are nodes of nerves and countless surrounding tissues. They can mediate the functional state of the body, repair the damaged part, and allow the body to reach the innocent body at the time of birth, thereby prolonging life. The so-called immortality and indestruction of Vajra refer to the realm.

After that, the human body was exhausted and there was no way ahead. Li Zhong's martial arts career came to an end. In the following years, Li Zhong continued to learn various scientific knowledge and Feng Shui metaphysics in order to pursue the path of martial arts, looking for possible paths, and finally even searched for the graves of the ancient cultivators, looking for a glimmer of life. After exhausting all possible, he came to this world by chance.

Now seeing the books about energy pipelines in this world, Li Zhong couldn't help but think: "Is it possible that the physical constitution of the humans in this world different from that of the humans on Earth, and that they truly have active energy that can flow in the body? This is impossible, and the human body cannot withstand pure energy."

Thinking of this, Li Zhong's face changed a little, and then his eyes flashed with light, "No matter whether it is true or false, I just need to make some golden needles and try it. If it is true, it means I may have found a new path."

Thinking of this, Li Zhong almost wanted to leave immediately and go to the city to purchase or order the golden needle.

But after looking at the time, Li Zhong had no choice but to find that there was not enough time. It was only five o'clock now and there were still two hours of working time.

Li Zhong suppressed the excitement in his heart and continued to carefully check the mysterious book.

One by one, the knowledge about the energy ducts of the body was absorbed into his mind by Li Zhong. In just two hours, Li Zhong had already read all the books of hundreds of pages. Relying on his ability to remember everything, Li Zhong completed the results that others could not achieve in a year.

Through this book, Li Zhong discovered that this book did not seem to have been compiled in the Dark Age, but was printed in the previous era of Light Technology.

Li Zhong shook his head and saw that the time difference was not enough, so he stopped thinking about this. He packed everything, put the book in his own space backpack, and walked towards the commercial area in the mobile city.

It took half an hour to arrive at the commercial area. It was the time for the evening shift to change. There were pedestrians everywhere. The streets were very busy, but there were also many night owls, who had already started to go out and began to mess around in this prosperous area.

There is no shortage of entertainment venues in this era, because people may face threats at any time, so people still need to relax. There are naturally many places like bars and KTVs, and of course there are no special services. There are also many restaurants such as cafes and restaurants, which are opened by companies all over the entire human survival area.

After Li Zhong arrived at the commercial street, he went straight to the center of the guild building.

The golden needles in Li Zhong's mind can be made by only the alchemists in the Alchemy Guild. There is no sale outside, so there is no market to make them.

However, just as Li Zhong was about to enter the union, Li Zhong suddenly remembered that there were not many dark crystal coins on him, and at most several hundred dollars, which was not enough to pay for custom-made items.

Thinking of this, Li Zhong turned around and walked towards the other side of the commercial street. This is the place where the entire college city buys or sells various goods, such as dark beasts, medicinal materials, various potions, as well as special alchemy-level weapons, or mass-produced charging guns, and various outdoor adventure tools, which can be purchased here.

The merchants here all have close ties with guild companies, and their goods are basically obtained from guilds or companies.

Li Zhong's arrival was not at all noticeable, because there were crowds of people here, and they were all giants over two meters tall, or strong men with breaths of no-one all over their bodies, including students and countless mercenaries.

In just a short time, Li Zhong discovered many powerful people, and there were also many powerful mercenaries.

Li Zhong said inwardly: "It seems that there are also many dark powerful people in the army. Many people still like to live a life of blood licking from the knife. It is true that there are all kinds of people."

Li Zhong didn't look much. His power was not advantageous here, so he didn't want to cause trouble. He looked around the street. There were countless people watching, bargaining, and buying what he needed.

Li Zhong quickly chose a store that sold dark beast essence and walked in.

The owner of the shop immediately came over when he saw Li Zhong, and said with a professional smile: "We have everything this customer wants, even the third phase of dark beast meat that can be sold."

Li Zhong looked at the boss's eyes full of philanthropy and his voice remained unchanged: "I'm here to sell the dark beast. The second phase of the dark beast, will you collect it here?"

When the boss heard Li Zhong's words, he nodded quickly and said, "Cake it, of course, you have to see what dark beast it is. The better the quality, the more complete it is, the more valuable it is."

Then the boss said to Li Zhong: "My friend, please come with me."

Under the leadership of the boss, Li Zhong quickly passed through a portal and entered the depths of the store.

The two of them came to a hall where a square table was placed on the ground. The boss turned to Li Zhong and said, "Sir, you can put the dark beast you want to take action on this table. I'll estimate the price."

Li Zhong directly took out a second phase of dark beast that he had been assigned to when he was in the settlement. The dark beast was divided into two halves and the blood had long been dry. However, the temperature in the space backpack was low and there was no air, so there was almost no sign of a bad situation.

The boss looked at the dismembered dark beast that Li Zhong took out and took a breath. Then, after seeing the dark beast's appearance, he said in a surprise voice: "Isn't this an armored porcupine in the middle level of the second stage of the Dark Beast? This is a very powerful thing. It is not easy to kill with iron armor. Ordinary weapons cannot be repaid."

Seeing this, the boss pursed his mouth and looked around the corpse carefully, and slowly said: "Sir, this armored porcupine is worth about three thousand degrees of dark crystal coins."

Li Zhong heard that a second-phase dark beast was only worth 3,000 degrees of crystal coins, and his brow frowned slightly, but he let it go in a blink of an eye because Li Zhong had no time to compete with his boss now.

Li Zhong said to the boss: "That's it, I'm in a hurry."
