"From the moment it was born in the mid-15th century, the differential machine has been subtly changing people's lives and thus changing the world. However, in the first hundred years, its functions were still very primitive and limited. In the eyes of most people, it is just a mysterious tool, with no essential difference from a pair of pliers and tweezers, and has nothing to do with itself." Professor Nicholas stood up from the dining table, walked to the edge of the platform, and looked at the night view of the city, saying, "But there are a group of scholars who saw the infinite potential of this tool from the primitive simplicity. For this reason, they devoted their entire lives to the research and improvement of the differential machine. This is not an easy task, because this work not only consumes huge wealth, takes a long time, but is not understood by most people. It is considered a waste of resources and wealth and waste of their precious lives."

"Fortunately, these scholars did not give up. Through lobbying, they received support from thirteen medieval families. These thirteen noble families stood behind them and gave them unlimited support, financial, material and manpower, and whatever they wanted, almost at any cost."

"In the end, with the efforts of both sides, scholars' research has achieved amazing results. Over the past hundred years, differential machines have been continuously improved, their functions have become more and more advanced, and their influence has become larger and larger. From the initial simple computing tool, the scope of influence has gradually expanded to every field. It is no exaggeration to say that during that time, the world has undergone subversive changes every year. By the end of the 16th century, people suddenly discovered that their lives can no longer be separated from differential machines. Industry, agriculture, and even handicrafts, everything is closely related to differential machines. The steam cars on the ground, the airships in the sky, and the steam armors that people use to protect themselves and strengthen themselves, and each is the result of the development of differential machines."

Nicholas turned to the direction of the cathedral, his eyes were a little confused, as if he had seen something, and said in a dreamy voice: "In the past hundred years, countless scholars have devoted themselves to research and improvement, and most scholars have only made the academic foundation more solid, but sixteen of them have achieved remarkable achievements by stepping on the foundation laid by their colleagues."

"Ha..." Following Nicholas's gaze, the crow seemed to see the sixteen bronze sculptures outside the church door, "Sixteen Saints?"

"Yes, it's them." Professor Nicholas nodded, "In the seventeenth century, the blowout development ended, and academic research on differential machines entered a stable stage, and the world's enthusiasm for differential machines gradually faded. However, scholars know that the potential of differential machines is far from being discovered, just like a huge treasure waiting for people to develop, but people are forgetful. If the enthusiasm of the world is allowed to fade, it will probably take decades for the world's views on related academic research to go back to the beginning, and scholars can only fight alone. They cannot tolerate it, absolutely cannot. If you two, will you watch things go to that point?"

"Why can't?" The crow shrugged and said lightly, "I am different from you. I don't think I have an obligation to help others improve their IQ, especially those stupid and self-righteous idiots."

Nicholas was speechless and found that he was speechless to a person like the Crow.

"But everyone has their own ideas, and they cannot force unification. The ideas of you scholars must be different from those of us ordinary people." The crow said indifferently, "So, in order not to return to the starting point, they used some small means."

"Yes, a little trick." Nicholas smiled self-deprecatingly, "So, with the first generation of differential machines as the totem, the scientific and research spirit symbolized by differential machines as the object of worship, and sixteen outstanding scholars who have passed away as saints, the Steel Church was established. At that time, most differential machine research scholars were concentrated in the Steel Church. It can be said that the Steel Church had mastered the scientific and technological authority of that era. Advanced technology will naturally attract the covetousness of all countries, but the technological power of the Steel Church is strong, and coupled with the support of thirteen sacred families that have grown into behemoths, those greedy countries cannot compete with the church at all, and can only choose to recognize the faith of the Steel Church in exchange for technical support. Those stubborn countries were cut off by the church's supply of technology and were soon annexed by other countries because of backward technology."

"After developing like this for hundreds of years, the Steel Church gradually became the co-lord of all countries. Even the rise and fall of the country and the change of royal power will be affected by the church. Because the church has always firmly controlled the relevant technologies of differentiation, and the priests in the church are all transferred by senior scholars, and they are not interested in interfering in secular power too much. All countries have gradually adapted to living under the influence of the church, and the two sides have formed a harmonious and good relationship of coexistence."

"Isn't this good?" The crow laughed and shook his head after he said that, "It was always quiet before the storm. Oh, the things in the world are actually similar. There are always some people who are not satisfied with what they have already obtained."

"In fact, they also have a good reason, ha, why should our country obey the command of one of your churches, even if it is only nominal subordinate." Nicholas smiled sarcastically, "So, in the mid-twentieth century, some countries with the same idea united and conspired to go to war with the Iron Church."

"They are not opponents."

"No, the whole world was divided into two camps at that time, and they were indeed at a disadvantage in number, but because they had been tolerant, the Iron Church had already created a large number of extinction bombs when they discovered their intentions."

"Huh?" The crow raised his eyebrows, "What is that?"

"A destructive large-scale weapon against the environment, after use, will not only turn into a barren land, but will also destroy the steam energy balance in the environment and cause environmental disasters."

"Tsk tsk tsk." The crow said, "This is a desperate bet and plans to die together. Why do I feel so familiar?"

"Blooded November." Rose replied coldly, "The military has survived with such a rogue threat."

"I know the story of your world," Nicholas said. "But the Steel Church did not give in, but chose to confront it head-on, intending to use technology to minimize the harm of the extinction bomb."

"Has the suppression been successful?"

"I don't know." Nicholas sighed, "The war ended before it even began. The rebels admitted their defeat and surrendered, and a world war came to an abrupt end."

"Wait, this happened in the 25th century? Two hundred years ago?"

"Well, two hundred and four years ago," Nicholas said meaningfully, "you seem to be very sensitive to the number two hundred years."

"Ha, it's an integer." Raven Yan said insincerely, "What's the reason for their surrender?"

"Top secret."

"Okay, okay, let me think about it." The crow pondered, "so six years after their surrender, the Iron Church split, and you and the Iron Church parted ways?"

"right."

"What's the reason? It's also a top secret?"
