Hearing Guo Kang's advice, Xiao Jeanna didn't say a word, but Zhu Wenkui was very interested.

"Can you understand other civilizations now?" He asked curiously: "After all, you have also been in contact for so long, and you have been in contact with each other, so you should have the experience of 'translating' each other." ”

"We often don't understand." Guo Kang smiled bitterly: "When we first went to school, we had to study not only the history of Serris, but also the history of Rome and modern Europe. As a result, everyone often complains that these three courses should not be juxtaposed at all. The history of modern Europe is too thin......"

"A history of Europe? Make up your own textbooks. Princess Jeanne asked.

"yes, it took a lot of work to do this." Guo Kang said with emotion: "My uncle presided over the compilation of this book back then, and left a special instruction, saying that in the future, it should be reviewed every five years and replaced every ten years. It's important to remember that this is just an outline, and there are likely to be quite a few mistakes. ”

"Why is that?" Princess Jeanne was a little strange.

"Because the information is too complex, and the credibility is questionable." Jeanne Jr., who has read the book, took the initiative to explain: "Many historical sources, which are records of churches in various places, do not have a clear official history book like Seris's as an outline. It's terrible. ”

"The official history books, while not always credible, provide a framework within which the overall timeline, sequence of events, and chronology of the characters can be determined. Even if some merits are exaggerated and some events are devalued, the impact on the overall context is limited. ”

"That's the trouble on our side." She shook her head and said, "If you really want to talk about the historical materials themselves, there are actually a lot. After all, churches have to do things like counting church memberships and accounting for taxes. Even the monasteries in the countryside have accumulated a large number of records over a long period of time. ”

"But the biggest problem is that the records can't be strung together. It's like just a bunch of pearls, but missing that thread. "In this case, if you want to write a general history, you have to find the information from scratch and then examine the connections between them," she said. That's too much trouble. ”

"That's right." Guo Kang agreed: "What is more difficult is that these materials still exist in different places. For example, if you want to write the history of a place, you can only search for records in the local area. With a bit of luck, the local clergy may have written some chronicles, but these are also regional and may not care about other places at all. Everyone's records may not be matched. ”

"It's really like pieces that it takes a lot of work for local scholars to sort them out, let alone outsiders like us. The local lords and churches are not necessarily welcome to look up the books. ”

"Since we can't go to many places, we have to commission a few scholars and businessmen to inquire – but this kind of inquiry is very inefficient. As the county lord said, their historical records lack context, and after a few generations, even they don't know when and where important events were recorded. ”

"It's like studying the war at the end of the Sui Dynasty, but you only know that during that time, all the churches said that the world was in chaos, and it was not even clear how long it had been fought and who was fighting whom. Because the records are full of the clergy's favorite theological parables and prophecies, some of them will make you think that Satan is going to attack heaven. He gave an example.

However, because of its great influence, some of the more reliable church historians also paid attention to the war and recorded many details. You learn that there was a famous battle at Tiger Prison Pass, and General Lee, who had been blessed by his Heavenly Father, was victorious. But that's all that is usually written in church history, and you'll have to find the rest yourself. ”

"If General Li's family is still around, then you're lucky, and you'll probably be able to find a relevant biography from their family's records for more detailed information. If you can't find it anymore, it's even more troublesome. The diocese where Tiger Prison is located may have some other perspectives, and if the ecclesiastical historian is reliable enough to accurately record its location, and the local parish monastery happens to have not been destroyed by the war, then it is possible to go there again and complete the record. ”

So far, this is only the one person who has been found. The question of who the rival Lord Dou and Lord Wang were—or whether they were human beings, or some strange and evil creature, had to be investigated. ”

"Don't laugh, this kind of swear is very common in depictions of wars with infidels." He shrugged his shoulders and said to Jeanne Jr.: "Considering that the struggle for hegemony in the Central Plains is also a legal struggle related to the right of sacrifice, its correspondence in Europe may be more exaggerated than this. And in view of the habitual exaggeration of European recorders, we have to examine the size of the enemy for ourselves—it is impossible for all of them to be as many as five million anyway. ”

"I'm talking about the basics. When it comes to real operation, even a duplicate name problem alone can make the history cultivator collapse. As I said before, they don't have a clear timetable. John Lee II of Jingzhao, John Lee III of Wannian, and John Lee III, son of John Lee II of Kyungzhao...... will mix together. The kind of famous nobles are better, and can be distinguished by nicknames and lineage order. If it's the kind of person who isn't particularly famous, you may not be able to tell who's who at all. ”

"That's right......" Princess Jeanne couldn't deny it, so she could only nod.

"At that time, we selected some events and composed a simple history book, and tried to write down the major events of each country, such as the establishment and collapse of the Franks, so that the students could have some preliminary understanding of it." Guo Kang replied.

"It's just that we didn't be able to sort it out too much at that time, so we had to entrust others to collect it slowly, and then gradually make up for it. But even so, this part of the content is still much thinner than the other two. ”

"It's history." Zhu Wenkui complained: "Is this thing necessary to learn?" Isn't it just ......"

He wanted to mock the barbarians, but Princess Ma glared at him. Zhu Wenkui was stunned, looked at Jeanna's mother and daughter again, and stopped talking.

"It's still necessary. Especially the hostile countries of our north. It's harder to understand them, but it's still a bit harder to research. Guo Kang said: "Only by understanding the enemy can we defeat them more efficiently." ”

"Didn't you just say that these people are not easy to understand?" Jeanne asked, "Is it useful to learn this?" ”

"You don't need to understand, you just need to know the general logic of their behavior." Guo Kang told her: "Like us now, we have summed up three basic rules when fighting. ”

"What's that?" Jeanne Jr. wondered.

"If you can fight and peace, you will fight; can be punished or forgiven, then punished; If you can attack it, you can attack it. Guo Kang said: "This is also what my uncle summed up back then. ”

"Although I myself often can't understand their way of thinking, these lessons learned from the enemy's behavior are obviously very useful, and they are called the 'Three Principles of the Guo Family'. We still use it to this day. ”
