Studying scholars in this world are a very special type of people. They can be regarded as preparatory scholars. They pass exams similar to imperial examinations to obtain the qualification of study abroad scholars, and then travel between cities to record and promote various knowledge.

On that day, even if Xu Changqing did not meet the unlucky scholar of studying abroad, he would try to find other scholars of studying abroad and his luggage to replace him. After all, the identity of scholar of studying abroad can provide him with great help. At least 81 lower realms in Yongzhou, he can pass freely with this identity and will not encounter any obstacles.

Just like now, after Xu Changqing took out his documentary from the study tour scholar, the guards guarding the city gate did not make any trouble and let him in directly. He even skipped the level of the city protection array inspection that others had to conduct when entering the city, so that some of the methods Xu Changqing had prepared to cover up the array exploration these days had no chance to use.

After entering the interior of the mud city, Xu Changqing had not had time to see the situation in the city, so he immediately found a pavilion set up near the city gate to rest and sat down, quietly released his divine thoughts and magic to investigate the situation inside the city.

The moment he officially entered the inner city, Xu Changqing felt that the city inside and outside the city were simply two worlds. Outside the city, any magic that was used to release any extraordinary power that was not physically qi and blood, would be absorbed by the invisible laws in this world and become one of the forces to protect this world.

However, inside the pastoral city, this ubiquitous law of heaven and earth was greatly weakened by the invisible power in the city. Just like the spell he cast now can still save more than 60% of the effect, which is twice as much as outside the city.

Soon Xu Changqing discovered the reason. He discovered that the reason why the invisible force in the city was produced to resist the swallowing of heaven and earth was entirely because a foundation stone was laid on the bottom of the entire city. According to Zhen Yuanzi's memory, this foundation stone was also particularly famous in the ancient times. It was a special stone called veins, which was mainly used to lay the foundation for the cave.

It is said that the earth vein stone can imitate the flow of the earth vein. If a spirit gathering array or a defense divine array is arranged on it, it can form a miraculous effect of endless rebirth and constant flow under the action of the earth vein stone. Therefore, most powerful caves in the prehistoric world use earth vein stones as their own caves.

The foundation stone of the city laid underground in the pastoral city is used for this kind of earth vein stone, and no additional magic array or divine array was added to this earth vein stone. The characteristics of the earth vein stone itself alone have formed a special innate seal inside the city, which has a certain resistance to the power of the law that permeates the entire world.

From this point of view, people who live in the city for a long time must have a much longer life span than those who live outside the city. At the same time, due to the influence of the special environment here, the defensive magic array inside the city can play a more obvious role. Think about it, if someone outside the city rebelled and attacked the city, the people in the city only need to activate the magic array on the city wall to wait for it easily, while the other party is weakened by the power of the law that absorbs extraordinary power, and it is impossible to bring any damage to the city.

This may be the main reason why the Heavenly Palace can always rule these prefectures and cities, and no one can overthrow them. If you want to achieve this goal, you can only do it from the inside, just like the resistance organization where the bookstore owner is located.

Thinking of this, Xu Changqing couldn't help but feel a little suspicious, because it is not difficult to infer from his understanding of the giants in this world that these giants are acquired creatures, with incomplete souls and lack pioneering spirits, so over the years, they can only promote the evolution of their own civilization bit by bit by bit by bit by continuously absorbing knowledge from external civilizations. However, the current method of the mysterious resistance organization is obviously carrying a trace of pioneering, which is contrary to Xu Changqing's speculation that can almost be regarded as facts.

It is not difficult to see from the books Xu Changqing has read these days that some rebellious things have happened in the nine states of the heavenly palace in this world in the past, but all those who instigated the matter took the same method without exception, which was to blatantly recruit people outside and then attack the city. The result is naturally self-evident.

But the current resistance organization has adopted a strategy that is countless times more intelligent than in the past, lurking down and infiltrating into various cities, controlling the power of each city bit by bit. Even the Heavenly Palace may have been penetrated by them. Such a completely different, but mature and effective approach is absolutely impossible for the wise man in this world to easily think of it with a pat on his forehead. There must be external forces involved, and this external force is probably the same as Xu Changqing's purpose, all to create civil strife that is enough to make the Heavenly Palace unable to take care of itself, so that he can get the chestnut from the fire.

"Brother Gu Nian, you are finally here! I have been waiting for you at the city gate these days, and finally waited for you. If you don't come again, I will send someone to Lucheng to inquire about the situation." Just as Xu Changqing was investigating the surrounding situation, he suddenly rushed out of the roadside and walked quickly to Xu Changqing's side. While talking, he reached out to Xu Changqing's shoulder.

The person who came was not quick to take action, so Xu Changqing could easily dodge it. However, he did not dodge, but let the other party's hand grab his shoulder, and opened his eyes, looking at the other party with a very natural expression, looking very familiar with the other party, and said, "On the way here I came, I encountered a strange beast, and I suffered a little injury. I had been recuperating outside for a few days before I could leave to the city. It's been a long time since you wait."

Xu Changqing's behavior was extremely natural. Although he deliberately dodged the content related to the other party's identity, the other party obviously did not expect that the person in front of him was a fake. After hearing Xu Changqing's explanation, he asked about his physical condition with great concern, and then took the initiative to mention the salute Xu Changqing used to disguise and led Xu Changqing into the city.

The current situation is somewhat unexpected, but it is not a bad thing for Xu Changqing. It is obvious that from what happened just now, it is not difficult to judge that the study tour scholar who was disguised as a scholar who had probably completed his study tour experience and was awarded a position by the Heavenly Palace above, which happened to be in Mucheng.

Xu Changqing, who made a speculation in his heart, followed the lead man and deliberately talked with him. During the conversation, he directed his words to what he wanted to know, and soon asked for some useful information.

This information also confirmed Xu Changqing's speculation. The person he used to disguise was indeed a study abroad scholar who came to Mucheng to take office, and the position he replaced was the guard of the Tiangong Befu Library Pavilion, which was about to step down.

This position has no development potential in the eyes of most giants in this world, but it is the most suitable position for Xu Changqing, because the Tiangong Beppu Bookstore is almost an idle position, and like the bookstore owner outside the city, it is a place to keep idle people, and there is no possibility of promotion until death without accidents.

The man in front of him was so enthusiastic about Xu Changqing and was very familiar with Xu Changqing's appearance characteristics. He could recognize him at a glance, not because he was very familiar with Xu Changqing, but because Xu Changqing was his only chance to be promoted. If the study scholar disguised by Xu Changqing did not come to take up his post, he would have to stay in this position.

Xu Changqing, who knew the situation, couldn't help but be glad that he had been cautious in his previous words and did not do too much extra behavior, otherwise he would probably be seen by someone.

Soon the two arrived in front of the Tiangong Beppu, located in the center of the city. This Romanesque cylindrical dome building stands out from the crowd of countless Eastern wooden structures, and is extremely eye-catching. A large number of local scribes and study scholars talked loudly in the square in front of the building, which seemed extremely lively.

Although the person who led Xu Changqing here worked in the Beppu in Tiangong, his status did not seem to be very high. When he arrived in the square, there was no one to say hello, and he could not even go to the main entrance. He could only enter the Beppu from the small door of the side hall, and walked along the path next to the Beppu wall to the library behind which was surrounded by trees and was extremely quiet and deserted.

After bringing Xu Changqing, the guard of the former library could not wait to handle the procedures for Xu Changqing's transfer of positions. Because the pre-order documents for various procedures had been prepared long ago, the process was very fast and smooth, and Xu Changqing was also a little surprised. Originally, he thought that there would be some identity checks when taking over the position, such as using certain magic circles to check physical condition, etc., but none of them were there. He just signed some documents, and then handed over the key to opening the library, injected a magic power again, and completed the entire job handover.

Such a slack internal system made Xu Changqing feel that after so many years of long and stable rule, the internal internal decay may have been extremely corrupted. Even without him intervening, the resistance organization behind him who was guided by someone behind him could quickly subvert the rule of this realm in Jiuzhou Prefecture City. As for whether it can truly threaten the upper realm Tiangong, this is just an unknown. In this place where Taoism is revealed, a powerful existence is enough to influence the ownership of the Lord of Heaven and Earth. I think there must be such a strong man in the Tiangong.

After completing the transfer of positions, the guards of the former library could not wait to hold the luggage they had prepared in their hands, and no longer had the enthusiasm he had before. They quickly moved away from this ghost place that had trapped him for more than ten years as if they were hiding from the plague god.

The former guard left as Xu Changqing wanted. He threw his disguised luggage into the guard residence next to the library. He did not pick up the daily routine manual on the table, but directly picked up the key and opened the door of the library and entered the huge library that was as high as six floors and a diameter of 500 meters.
