"You have done it well, why should you continue to add some unnecessary things?" Leo closed the research report in his hand, and then said to the fourth urban tutor who came to seek help with the study bottleneck, "You have already obtained a stable formula in one hundred and seventy-three experiments. All tests meet your initial research goals, and even better. Why do you have to add some unnecessary things to destroy the stability of the formula?"

"I just want to make it more powerful." The tutor from the fourth city district looked like a student asking for teaching rather than a scholar who came to communicate knowledge.

The mentor's face and hands were covered with scars on his face and hands, one eye was also prosthetic, his ears were deaf, and he needed to wear a special hearing aid device. Moreover, his skin was burned on his body, which made him look very scary.

His name is Rowell, and he is a very famous mentor in the Fourth City. He is famous because all the assistant scholars involved in his research died, and everyone's death was very miserable, and almost none of them could be buried in a state of complete corpse.

The reason for this is mainly because his research project is a kind of gunpowder used by countries around the world today. Whether it is the scars on his own or the dead assistant scholars, they are all due to failed experiments again and again.

The gunpowder used in this world is very unstable, including both the gunpowder formula and the world's laws. For example, the gunpowder with the same formula is more stable and more powerful in the New World. However, in the Old World, the power becomes very chaotic, sometimes large and sometimes small, and the trigger is extremely unstable, so the army of the Old World is still mainly based on cold weapons.

However, because the effectiveness of New World countries such as the Otter Federation after using gunpowder weapons as an example, even though gunpowder is very unstable, countries in the Old World have not given up on the development and research of gunpowder formulas, and even the True God Church is conducting related research.

As the place with the most wise men in the world, the Academic City naturally has its own gunpowder research project, and more than one. Among these gunpowder research projects, Rowell's research is the most valued, because his formula is much better than other formulas in terms of power and stability. For this reason, the School City specially built an extremely strong laboratory for him near the School City, and there were also the Legion of the Kingdom of Teresa to guard it.

It is also because of this that even though Rowell is the tutor in the fourth city, he rarely appears in the school town. Most of the time, he does experiments in his own laboratory.

As usual, he and Leo would not have much intersection, nor could they ask Leo for help with his research report, but what is interesting is that such a person who devotes himself to his research project and is indifferent to foreign affairs is a fanatical omniscient chess enthusiast. Leo is one of them in the challenge of fighting against a thousand, and he is also the last few players who admit defeat.

Because of this reason, he was extremely respectful of Leo's knowledge. After tentatively asking Leo about his difficult questions in his experiments and obtained very useful answers, he decided to give his research report to Leo to see if Leo can help him solve the problems that have been bothering him for many years.

However, some problems arose when his decision was implemented, because Leo was a foreign scholar after all, and his research designed the most important secrets of the School City and the Kingdom. Therefore, the management discussed this matter and consulted the Kingdom for a while. Finally, he decided to agree to show some of the research reports to Leo, and remove the contents involving specific recipes.

However, these people did not expect that even if Leo did not see the formula, he could infer the complete formula through the experimental process and some fragmented information disclosed in the report, and even speculate the formula ingredients modified by Rowell every experiment.

When Leo looked through the research report, while inferring the recipes one by one, and completely restored Roele's thoughts and intentions at that time, Roele's mentality could no longer be described as shock. Moreover, he no longer respected Leo, but worshiped like a believer. He even gradually recognized the rumors outside that Leo was the incarnation of the Spirit of Knowledge.

However, Rowell did not know that Leo was also shocked by him when he was looking through the research report. The reason why Leo was shocked was not that Rowell's in-depth research on gunpowder was far beyond the vast majority of people in this world, but Rowell's good luck and vitality.

The number of experiments recorded in the report was as high as 300 times, of which 294 failed records. Among them, nearly 90% of these 294 failures occurred instability during the ratio, which directly detonated. The ratio of each new formula was operated by Rowell himself.

In this case, the person who matches the ratio cannot escape the range of the explosion at all. In other words, Rowell has suffered more than 200 explosion injuries directly over the past few years. But what is amazing is that Rowell is still alive now, even though he is covered in bruises, his luck and vitality are obviously extraordinary compared to the assistant scholars who died in the explosion, and such a person is just an ordinary person.

In addition, Leo also found that Rowell's experiment had been successful for a long time. He obtained a stable formula in the 173rd experiment. The only flaw was that the power of the explosion was slightly smaller and only met the minimum standard of the research goal.

Because of this, Rowell still did not stop researching and continued to add different materials to this formula to try to improve its power, but he still did not get the desired results.

After discovering the problem, Leo directly gave a pertinent suggestion, but obviously Rowell did not intend to accept this suggestion.

Rowell's reaction was not beyond Leo's expectations. He thought for a moment and said, "You can try to use the two recipes in combination."

"Two recipes?" Rowell didn't quite understand what Leo meant.

Leo explained: "In your early sixty-seventh experiment, the power of that recipe has met the standard requirements of your research objectives, but it is very difficult to trigger the explosion. You can use that stable recipe as the trigger for this recipe..."

"I understand!" Before Leo finished speaking, Roell jumped out of the chair. He seemed very excited. Without saying anything to Leo, he ran out of Leo's office like crazy, making people outside feel extremely puzzled, curious about what Leo had said to Roell just now.

Sylvia, who had been by the side since the beginning, picked up the research report that Rowell had not taken away, looked at it, and asked thoughtfully: "Will the suggestions you just gave work?"

Leo did not answer immediately, but pondered for a moment and said, "The final effect may be much more than he expected."

"This is not a good thing," Sylvia said again.

"It depends on who is right." Leo responded.

There is no doubt that it won’t take long to appear a powerful and stable new gunpowder in the Old Continent, and the weapons that match it should also appear. This will definitely change the situation in the entire Old Continent. It is unknown who can benefit from this change in the end, but it is certain that the Church of the True God or Heretics who master the most extraordinary power will not be the winners.

Afterwards, the two refused other visitors, put on the burqa that was exclusively a senior mentor, left the back door of the laboratory building, and walked towards the large library in the fourth city area.

As early as a few days ago, after they obtained the status of senior mentors, they knew that they did not need to accumulate additional points. The authority of senior mentors has already made them qualified to access banned books in the large library in the Fourth Urban District.

Therefore, they submitted the relevant application that day, and the application was not approved until today. They were allowed to enter the Fourth Urban District Large Library to check any information within the next three days. There is no time limit for accessing the information, nor is there a reading limit, but the premise is that there must be a secret keeper in the forbidden book area, because many of the forbidden books contain dangerous powers. If you are not careful, you will be corrupted by the force. The secret keeper needs to restrict or imprison those dangerous forces on the side to be able to read safely.

During this period, Leo and Sylvia also learned about the situation of the secret keeper through various channels, but even scholars or mentors from the school city did not know much about the secret keeper.

Now I just know that there is a secret guard organization within the Xuecheng City. This organization is not under the jurisdiction of Xuecheng City, and its relationship with Xuecheng is only a partner. No one of the direct superiors of the Secret Guard organization knows it. It is just that some people speculate that it may be related to the first school dean, because the shape of the Secret Guard's badge is almost the same as the exclusive badge of the first school dean.

Almost all secret guardians themselves have a very magical restriction power. This force can limit and weaken all extraordinary powers, whether it is the power of evil gods, bloodline power, or the power of true gods. They will be suppressed and weakened when encountering such restriction power. Therefore, all items involving extraordinary power in the school city are supervised by secret guardians, and even the royal family and the Belmont family have hired a group of secret guardians from the school city to be responsible for guarding some special power items.

No one knows where these secret keepers come from, and how they are produced. The only thing they know is that every time a secret keeper will join, and the secret keeper will not have any entertainment activities, no ordinary feelings, and naturally they will not love and marry. They will not retire until they die. Therefore, many people in the Xuecheng City call them stone people.

Leo and Sylvia have tested the ban power of secret keepers. They found that the ban power of these secret keepers is related to their age. The older they are, the stronger their strength. In the sealed building of prohibited items in the second city, there is an old secret keeper in his seventies. The ban power on him has begun to have a significant suppression effect on the power of Leo and Sylvia.

According to Leo's inference, if there is a secret keeper over a hundred years old, even a demigod will be suppressed to be similar to an ordinary person.

However, it is basically impossible for a hundred-year-old secret keeper to exist, because while these secret keepers have this restrictive power, their bodies will be greatly weakened. For example, the secret keeper in his seventies can be said to have reached the limit of lifespan, and the lifespan of most secret keepers cannot reach this level. According to records, most secret keepers died of various diseases at around the age of forty.

Leo also tried to judge where these secret keepers came from based on their accents and habits, but the result was disappointing. The accents of these people were all very standard local official languages ​​of the Teresa Kingdom, and the standard level was even better than that of the locals. Their habits were like ordinary people, and they could not find any useful clues from them.

Even so, Leo still speculated about the origin of these secret keepers. He felt that these secret keepers did not arise naturally, but were produced according to some intelligent module like he did in the past, because these secret keepers had almost the same living habits, methods of doing things, and indifferent attitude towards the outside world, which made him feel like a biochemical person.

For this reason, he went to the cemetery next to Shuzhen that specifically buried the secret guards, and took away some of the bones on the bodies of more than a dozen secret guards.

Although the secret keeper has a powerful restraining power in front of him, he is no different from the corpses of ordinary people after his death. That kind of power also dissipates from them with death. No way can he recover their power in his lifetime. Even through a certain degree of resurrection, the secret keeper after his resurrection is just ordinary people.

Therefore, Xuecheng and the Secret Guardian Organization believed that no one would be interested in the corpses of the Secret Guardian, so they did not conduct special guards on the Secret Guardian Cemetery. When Leo took the remains of the corpse from the cemetery, no one naturally stopped them, let alone discovered them.

It is precisely because these secret keepers no longer have that kind of restrictive power, so Leo did not show any abnormalities when decomposing and analyzing these bones through witchcraft and other methods. After the analysis, he became increasingly sure of his previous guess that these secret keepers were artificially created and used the bloodline of the same person, because all the secret keepers' bones were completely consistent after analysis. These secret keepers are most likely a group of clones who have been transformed in shape.

Leo told Sylvia about her discovery and the clones. Sylvia was also very surprised when she found out, and she also had some associations, thinking that the bloodline used by these secret keepers would be Rupert Fitz's, and it might even be Rupert Fitz was still alive, secretly creating and controlling the secret keepers organization.
