Spectacular is the only feeling that anyone who sees this giant arch bridge has. The subsequent idea is that this kind of building should not exist, and whether they see only doubts such as fantasy.

In fact, not only those who see this arch bridge at first glance will have this idea. Even if scholars who have lived in the academic city for many years and walk back and forth on this arch bridge will still have similar emotional fluctuations when they see the arch bridge.

A giant arch bridge that is hundreds of meters long and more than ten meters wide spans from the top of the mountain peak here to the top of the opposite mountain peak. The clouds and mist in the mountains float under the arch bridge. Walking on the arch bridge is like walking in the sky. This shock cannot be felt in other places.

Even when Sylvia saw this arch bridge, she was lost for a long time before she recovered from the shock. Not to mention Penny and Joan, they could only stare at the arch bridge in front of them, and couldn't help but repeat words like miracles.

The emotions expressed by Sylvia, Penny, Joan and others seemed normal to Delkan and others, because in their memory, people who had never seen this giant arch bridge for the first time would not show a similar look of shock.

But they soon discovered that the first exception seemed to appear, because the calmness shown by Leo made people wonder if something was wrong with his eyes, and whether the spectacular giant arch bridge in front of him turned into air in front of him.

"Mr. Leo, have you ever seen such an arch bridge before?" Delkan couldn't help but wonder and asked Leo.

"No." Leo shook his head and said.

Delkan asked again: "Then why do you look so calm? Isn't this building shocking enough?"

"It's shocking. According to the current world's construction technology and capabilities, this kind of giant arch bridge is absolutely impossible to build. However, this kind of arch bridge is real, and there is more than one." Leo said, his eyes shifted to the distance, looking at several other similar cross-mountain arch bridges, and then retracted his gaze, turned around and said calmly: "But I have seen buildings that are thousands or ten thousand times more spectacular than this arch bridge, so this arch bridge cannot impress me."

"Thousand times spectacular, ten thousand times?" When they heard Leo's words, both Delkan and Pol subconsciously felt that Leo was bragging, but then they saw the calmness on Leo's face, and they all felt that what Leo said might be true, and they could not imagine in their hearts what a building that was thousands of times spectacular and ten thousand times more than this arch bridge. Perhaps only the legendary palace of gods could do it.

At this time, others also recovered from the shock of the arch bridge construction. Boer continued to lead everyone to the second urban area opposite the arch bridge. During this process, Delkan introduced some stories about the arch bridge to Leo and Sylvia. Most of them were some architectural scholars' research on the construction methods of the arch bridge, etc.

At the same time, while listening to Delkan's introduction, Leo used the spiritual network to check the situation of the arch bridge and searched for the construction secrets in the arch bridge.

However, the questions that plagued all kinds of scholars and architects in the academic city for many years were solved by Leo after scanning them two or three times through the spiritual network. He was very sure that the construction process of these cross-peak arch bridges absolutely used stone remodelers specially designed by the Earth Federation for the colonists.

Generally speaking, colonial spacecraft use dedicated colonial cabins as residences. The materials and equipment used in this colonial cabin can be used normally for a long time. This time can last for thousands or even tens of thousands of years. In the era when Leo was located, there were still early Earth colonial cabins in use.

However, the number of colonial cabins is limited. Once the planet's colonization enters the middle stage and the population begins to explode, the colonial cabins will definitely not be enough. Therefore, local building materials must be used to build residences. In order to facilitate the construction of desired residences, stone reshapers that can reshape various stone forms according to the desired form will come into being.

The early stone reshaping machines were very large, equivalent to a fifty-seater land chariot, but by the time of Leo, the stone reshaping machines had become smaller, almost like an ordinary rifle.

The special rays emitted from the stone remodeler can make most rocks clay, and then the clayed rocks are changed to their form by manual or mechanical means, and then shine with solidified light to make them return to a hard state.

Rocks that are reshaped through this method have one common characteristic, that is, the density of the rock will increase several times or even dozens of times compared to before shaping, because the cured light of the stone reshaper is not only reducing hardness, but also compressing the rock to increase its density. Therefore, this type of rock is not only stronger than normal rocks, but also heavier in weight.

Although Leo has never seen the honey-like stone used to build arch bridges and cannot compare the density differences between the two stones, he can horizontally infer how strong the high-pressure environment is needed to produce such a high-density stone. The strength of the life produced in that high-pressure environment is definitely far greater than that of civilian steel.

Therefore, Leo immediately determined that the honey-like stone used in the arch bridge was definitely not produced in normal environment, but was re-cured through a stone reshape reshape. Only stone with a strength of more than ten times can be suspended for hundreds of meters without other support, without being crushed by its own weight.

Leo's expression on his face, who had solved the mystery of the construction of the arch bridge, changed slightly, and Sylvia on the side was very familiar with what Leo's expression represented, so he asked tentatively: "Have you cracked the secret of the construction of this kind of arch bridge?"

Leo nodded slightly, but was still a little more conservative, saying, "It has been confirmed that 80% or 90% of the remaining 10% can only be fully confirmed if the equipment was found during construction."

Although there are people on the arch bridge, there are not many people. In addition to scholars and students traveling to different urban areas, there are more architecture scholars and students who are addicted to studying the mysteries of arch bridge construction. Because the surrounding environment is very empty, even though Leo and Sylvia are talking very little, many people can still hear it clearly, which makes many people unable to help but look at Leo and Sylvia.

However, after just looking at Leo and Sylvia, these people immediately with a look of mockery or contempt, they immediately withdrew their attention and continued to do their own things. It was obvious that they all regarded Leo and Sylvia as sensational people.

No wonder they thought so. After all, the construction mysteries of these cross-peak arch bridges have plagued the academic city for many years. Countless architects from all over the world have not been able to find any useful clues. Countless speculations that are so wonderful have been overturned. Now a stranger suddenly said that he had solved the mystery of the construction of the arch bridge. How could other people around who know the situation of the arch bridge not think that the other party is sensational?

However, Delkan, who knew Leo a little about Leo and knew that Leo was extraordinary, did not treat Leo like others. Instead, he asked expectantly: "Mr. Leo, have you really cracked the secret of the construction of this arch bridge?"

Delkan's inquiry once again attracted the attention of some people, some of whom also recognized Delkan's identity and did not understand why the famous tutor in the school town would ask about such an obvious lie.

However, Leo did not give the other party a positive response, but simply asked back: "I remember the stone used in this arch bridge is honey and gold stone? Are you sure?"

"Of course, it is certain that the stone of the arch bridge meets all the characteristics of honey and gold stone." Delkan responded, and an architecture instructor who led the students to study the structure of the arch bridge not far away could not help but stand up and said.

"Don't be so sure, compare the hardness and weight before talking about it!" Leo smiled and looked at the architecture instructor, gave a simple reminder, and then he didn't seem to have the intention to continue and continued walking across the arch bridge.

After hearing Leo's words, the architecture instructor did not immediately refute, but stood there in a daze, as if he had really gotten something else. The students around him also looked at his teacher with confusion.

At this time, Delkan, who was following Leo, also showed a thoughtful expression on his face. Obviously, the prompt Leo gave not only touched the inspiration of the architecture tutor, but also made Delkan, who was not from an architecture, think of something.

The use of honey stone for arch bridges is a recognized fact that all scholars engaged in arch bridge research, because the person who discovered this was the most outstanding geology and architecture master at that time. In everyone's opinion, this master would never be able to judge the type of stone used in the building. Moreover, the characteristics of honey stone are so obvious that even ordinary geology or architecture students can judge it. In the eyes of many people, there is no possibility of error.

Because of this, later arch bridge researchers also focused their research on the construction method, and no one really questioned the problem of stone, and no one would knock a piece of material from the arch bridge to compare it with honey stone of the same weight. Otherwise, previous researchers would have easily discovered from the hardness and weight that there is a huge gap between stone and honey stone of the construction of arch bridges. This gap can even be regarded as two materials.

Just after Leo and the others walked out for a distance, a sudden riot sounded from behind him. When everyone looked back, they saw several Xuecheng City Guards in charge of the safety of the arch bridge pressing the previous architecture tutor to the ground. The tutor was holding a small hammer in his hand. The students around him looked at the chaos in front of him at a loss.

It is not difficult to guess what happened just now, obviously the instructor of architecture was inspired by Leo and wanted to knock down a piece of debris from the railing of the arch bridge and take it back to compare the density and weight. As a result, the city guards who were patrolling back and forth were discovered and arrested as a destructive member.

The reason why the city guards have such a big reaction is that in addition to the importance of the arch bridge itself, more importantly, there have been more than once before, when people from the anti-School City sneak in to cause damage. These arch bridges connecting different urban areas are the focus of their targets. Therefore, the Xuecheng City will add additional city guards to be responsible for safety at both ends and middle of the arch bridge. Of course, the external school city only declares that it prevents people walking on the arch bridge from being too addicted to the surrounding scenery and jumping down, so it will add people to protect safety.

Delkan looked at the scholar-instructor who was pressed under the city guard and kept explaining his purpose. He felt like laughing, but at the same time he felt a little scared, because just now he had the idea of ​​knocking down a piece of fragments. After all, the appeal of cracking the mystery of arch bridge construction is too great. Even if he is not engaged in the discipline of architecture, it is still difficult to resist the temptation of solving the mystery.

"This bridge cannot be destroyed with a hammer." Leo looked at the situation behind, then looked at Delkan and Pole, who were still eager to try on their faces, and prompted.

As he said, after the density of honey stones on this bridge increased so much, its hardness was far greater than that of normal rocks. Not to mention a hammer, even if it was installed on a steamer at full speed on a ring rail, it would not necessarily cause damage to its surface.

So in Leo's view, if the management of Xuecheng City knows the hardness of these arch bridges, then they have sent so many city guards to the arch bridge, and their purpose is probably not to protect the arch bridge. It is likely to be using this practice to cause misunderstandings to those anti-xuecheng forces, mistakenly thinking that the arch bridge is easily destroyed, and then use the arch bridge as bait and trap to lure those anti-xuecheng forces into the bait.

The group did not stop to watch the subsequent development of the matter and continued to walk towards the second city area. On the way, Delkan and Poul were no longer as excited as introducing the situation in the school city to Leo. They were all full of worries, and the eyes of looking at Leo became strange. They seemed to have a lot of questions to ask, but they didn't know how to speak.

Leo did not answer their questions either. He and Sylvia were all focused on feeling the gradually increasing suppression and repulsion around him.

As they approached the second city, they all found that the situation in the second city was completely different from that in the first city. It seemed to be enveloped by an invisible forbidden area. This forbidden area had some effect similar to the laws of the world. This law was only aimed at those who had extraordinary power. They had a certain suppression and weakening effect on any extraordinary power. It is hard not to remind people of the phenomenon of the divine forbidden area that appeared in the territory of Teresa's Kingdom. Therefore, there are also people in the outside world who have academic cities mastered the method of creating the divine forbidden area.
