The locomotive roared up again and disappeared. Only Connor was left standing in front of the building, only to see the top of the giant gate of the building as high as 100 meters, and on a huge plaque with a length of more than 10 meters, there were four golden ancient texts - "Zhengque Treasure Paper"!

On either side of the gate, two masked men stand with their hands behind their backs. Seeing that these people are actually the special guards of the Black Castle, this is the place where the Black Castle operates. According to the security regulations of Black Castle, these guards are simply dispensable.

In front of the huge foyer of the Zhengque treasure paper, people of all colors come and go from time to time. This is the four characters of Zhengque Treasure Note, as the name suggests, it is similar to the treasure record pavilion of the stone arch city.

This place is the place where the books containing the method of energy cultivation are recorded, but the Zhengque treasure paper here is not comparable to the book collection in Shipai City.

Without thinking about it, Connor followed a group of people into the treasure note.

Whoever comes to this black castle can read any book in the pavilion for free. It is not copied, and can only be watched in the cabinet. This is not a problem at all, there is no place to rest in the Black Castle, and the Zhengque Treasure Paper is open to the public 24 hours a day. As long as you enter this Zhengque Treasure Pavilion, it is no problem if you don't come out within ten or eight years.

Connor followed the group through a large hallway, and his eyes suddenly became clear. A hall with a circumference of thousands of square meters comes into view, and a circle of circular bookshelves is placed around the hall, and the bookshelves are filled with all kinds of books.

Hundreds of long ladders as high as tens of meters are erected next to the bookshelves, and from time to time people climb the long ladders to go to a higher position to select the books they need. Connor was a little surprised to see some of the men clumsily climbing the ladder to search for the book collection, and it was hard to imagine that these people were all high-ranking samurai no less than him.

But when Connor stepped into the hall with one foot, all that thought was gone. He only felt a tightness around his body, and the energy in his body lost control in an instant, and he didn't feel that there was still energy in his body for a moment. The use of energy is absolutely forbidden in this treasure note, and the energy prohibition system is working all the time.

I saw that in the main hall, everyone sat alone on the ground, and only a few people would gather together. Quietly flip through the books in your hands.

In the only corner of the hall was a jade table, and a middle-aged man in plain clothes sat in front of the jade table, looking at those who were taking books and reading them with a smile on his face. This person is the only administrator in the Zhengque Treasure Paper.

He looked up at the top of his head, and saw that the building was not high. The edifice is indeed roofless, and the first construction of this edifice is a hollow roofless structure. In the center of the hall, a glass column with a diameter of tens of meters resembles an optimus pillar.

Seven or eight glass elevators were built around the pillar. From time to time, someone hurried into the elevator and went to the higher level of the building.

Connor walked around the hall a few times, and was surprised to find that 80% of the books in the Zhengque Treasure Paper were actually the methods of dark energy. It's just that less than twenty percent of the books are about primordial energy. However, it is only this 20% of the book collection, and looking at the height of the hundreds of floors of this Zhengque treasure note, even if it is small, it is definitely beyond the reach of the Treasure Record Pavilion.

Connor searched for it for a short time, and found a few copies of what he needed. He found a long ladder that no one was using, so he clumsily climbed up the long ladder and took down the books, and took out one of the tattered ones.

With the books in his hand, Connor found an inconspicuous corner of the hall, and like everyone else, he sat down on the floor without caring whether there was dust or not on the floor beneath him.

Connor could read the books at a glance, but he read three of them in just a few hours. Then he slowly closed his eyes, recalled in his mind what he had just seen, and the text he had read before flashed in front of his eyes, and after a few hours, he reviewed them all. These are of great use to the First Emperor's unforgettable skills.

When he arrived at the tattered book, Connor's face was much more solemn, and it was not for nothing that the book was broken. This book Connor looks at for three hours, and its content is not comparable to those ordinary books.

After reading this book, Connor closed his eyes again and reviewed it. After confirming that nothing was missing, the books were put back in their place.

Then he looked at the temple again, and found that there were not as many people who had come here to read books. Look at the administrator next to the jade table, it has also changed, and at this time it is a beautiful woman in green who is looking at the villain book at the jade table.

Although her head is lowered, you can see that this woman is beautiful even from the side. It's just that his ears are extremely round, so that the original decent appearance makes Connor's stomach churn for a while, he has no habit of discriminating against anyone's appearance, but in the face of those round ears, he always feels a little uncomfortable.

Anyway, it was over, and Connor didn't linger long to turn around and leave. But just as he was about to step out of the hall, he suddenly remembered something again.

Some of them looked embarrassed and calmed down. Walking slowly to the jade table, I saw that the woman was immersed in a book, as if she had not noticed her own existence.

Connor held out two fingers and tapped them twice on the table. The woman looked up at Connor unsatisfactorily, and this look was not as beautiful as she had seen before. It's just that the round ears on both sides look nondescript.

Before the woman could speak, Connor politely spoke first:

"Beautiful and kind fairy, I don't know if there is a sound battle method in this pavilion?"

As soon as the woman heard the word Yin Zhan, a hint of imperceptible discoloration flashed on her face, but in an instant, the woman came back to her senses and said with great interest:

"Sir is a musician, and the little girl has always admired the musician."

"How dare you call it a sound legalist, but it is strange to be a wave, and occasionally dabbles in the ear." Connor was very modest.

"Sir asked about the method of sound warfare, and how could he only dabble in it. If he has time in the future, I hope Mr. will not hesitate to say anything.

Forty-seven floors, maybe there's what you're looking for. The woman said lightly, and there was a bit of flattery between her eyebrows.

Although Connor did not have much contact with the woman, this woman was not the type he liked, and he just left in a hurry after a few polite words.

On the forty-seventh floor, Connor found some books on a bookshelf about sound warfare, but unfortunately these books were nothing more than explanations of Bo Neng. There are still more than 12 out of 10 people who can really practice the method of warfare, and they are all difficult and cultivation methods, Connor chose a method called "Void Peak Ethereal", this method of sound warfare can also make him sacrifice time to practice.

This Void Peak Ethereal and Bliss Sanskrit are completely different types of warfare, with the Ethereal Peak focusing on building illusions to haunt the enemy, while the Bliss Sanskrit focuses on substantial energy attacks. If these two kinds of sound warfare are combined into one, it will have unexpected effects.

Connor also found some extremely powerful energy skills in the Zhengque Treasure Paper, but after thinking about it carefully, Connor didn't take those skills to heart. As long as the energy in the body is sufficient, cultivating the bloody battle Huangquan to the fullest is just around the corner.

The final blow of the fifth layer of the bloody battle against Huangquan was an invincible skill under the gods, how could Connor take it lightly.

What's more, the most important thing is that he can't find any book about the energy heart method, and the energy in his body can be refined and purified by cultivating the energy heart method or the battle technique heart method. In addition to the introductory skills, almost every advanced skill will be equipped with a corresponding skill method.

Combat skills are just appearances, they are combat skills. The law of the mind is the inner enlightenment, the meditation interpretation of the energy path. The combat skills and mental methods have been trained, and the combat skills are not self-learned, and they are not self-coherent!

The method of sound warfare is different from ordinary combat skills and music scores, which are easy to remember and solve, and this method of sound warfare is complex and difficult, but it cannot be matched by any kind of combat skills.

Just this sound technique, Connor spent half a day memorizing and understanding. However, even so, he only understood the ethereal peak of this void peak in a small way. Anyway, it will be a long time coming, and for a long time in the future, this Zhengque treasure note is the place where it is patronized, and if you look at it a few more times, you will naturally be able to completely write it down.

Connor looked around and saw that there were very few people reading books in the treasure note. Counting the time, it's almost over. Thinking about it, Connor walked to the first floor, leaving the Zhengque Treasure Paper.

On a street, Connor was walking slowly, only to hear the sound of "grunting", Connor touched his stomach and smiled a little bitterly.

In front of a tavern, Connor stopped and entered. Nearly ten tables were set up in the small area of this tavern, and some of the guests ate meat and drank with relish. It's just that the meat on the table seems to have a sense of déjà vu.

Connor found an empty table and sat down. But when he saw the arrival of a guest, a strange man with four arms immediately walked over with a smile on his face
