Qin Feng found in a dossier called "The Records of the Founding of the Hundred Sons" about the changes of the Lingnan Wang family, the Saibei Hou family, the Xiguan Liu family and other major families, as well as several major sects including Luohumen. It seems that this book was written by the previous generation of pavilion masters, and the back of the file is also printed with the seal representing the pavilion master of the Breeze Fuyue Pavilion.

The reason why it is said that the previous pavilion master is not the current pavilion master Fan Yang'a, is because the silk silk used for writing has obviously a history of nearly 100 years, and the handwriting is also different from Fan Yang'a's.

Red Sleeves and Lan Ling also found several dossiers about the Northern Regions, which recorded several times of the captives' journey south, and they also recorded in detail the outstanding contributions made by the two major families of Nangong and Beiming.

Unlike the Nangong family, which is stationed in Yunzhou all the year round, although the children of the Northern Hell family are not weaker than any of the four major families in the east, west, south and north, they do not directly participate in the battle. They were more inclined to provide logistical support for the Nangong family and the generals of the Great Wei Dynasty army who were fighting on the front line.

The ancestor of the Northern Underworld family was born as a blacksmith and preferred to deal with those red-hot soldering irons by the stove, so the Northern Underworld family also became the largest supplier of weapons and armor to the army of the Great Wei Dynasty and the Nangong family.

According to Hua Feiyu's understanding, the reason why Zheng Pingping, Marquis of Jingping, was able to pull out a team of 50,000 people in just a few years, was due to the contribution of the Beiming family, and the armor and weapons of these 50,000 people were all handled by the Beiming family, and the quality and durability of the finished products produced by them far exceeded those of ordinary blacksmiths, not to mention that compared with the backward technology in the Northern Regions, it was simply a heaven and an underground.

There have been several wars because of these armor and equipment provided by the Northern Underworld family, so that Jingping Marquis Zheng Pingphong resisted the many attacks of the captives, imagine that when the fierce battle was in full swing, the scimitar in the hands of the captives continued to break and roll the blade, while the steel knives in the hands of the defenders of the Great Wei Dynasty were still strong, how exciting it would be!

Ouyang Xun quickly and carefully searched the files on the bookshelf, he couldn't read too many words, but after all, he also knew a few words such as "Great Wei", "Northern Regions", "Yu Yu", etc., he was also smart, and sorted out the books with these words at the beginning, just waiting for Qin Feng to look through them one by one, and then present them to the eldest sister Hua Feiyu.

As for whether he would mess with the bookshelf and let the pavilion master Fan Yanga punish him, this was no longer within the scope of his thoughts. He only knew that he had just shown his loyalty to a few people at this moment, and this thing was just right for him to vote.

"Well, kind of interesting. Qin Feng raised the corners of his eyebrows, glanced at Ouyang Xun who was still working hard in an encouraging manner, and turned around and walked towards Hua Feiyu.

Although there are not many bookshelves, because of this, Hua Feiyu is studying very slowly, and she is looking at a book called "Northern Regions Folklore Examination", which records in detail the relevant information about many ethnic customs and habits in the Northern Regions, but although it is rare, it has no practical help for the southern invasion of the captives.

Qin Feng walked in front of Hua Feiyu and saw her close the "Northern Regions Folk Customs Test" in her hand, and then handed over the book in her hand with a smile: "Eldest sister, take a look at this." ”

"General History of the Northern Regions!"

Hua Feiyu's first reaction was: This author has such a big tone and courage! He dares to go deep into the Northern Regions to write such a book, but as she opened the book, her eyes gradually became solemn.

Because it was not written by a person from the Central Plains, but by the people of the Northern Regions themselves.

Perhaps it is a problem with the translation of Qi language, but many places in this book have an obvious Qi language structure, and each sentence is accompanied by the original words of Qi language. Because the language is too obscure to be translated in the original language, the translator simply uses the Chinese language instead, and marks the possible meaning of the language that he himself deduced on the side, which is very difficult to read.

But it is such an obscure book, but Hua Feiyu continues to harvest surprises.

One of the words mentioned in it made Hua Feiyu's eyes shine.

Ice age!

Hua Feiyu definitely remembered these three words, because he had seen this word in more than one book about the Northern Regions, but those books were only hastily introduced, and the author must not know what kind of meaning it had.

However, this "General History of the Northern Regions" is different, the author himself is a captive person, and he has a deeper understanding of the Ice Age than the Central Plains people through word of mouth, and it is even very likely that he has experienced it himself. The fear and deep awe of the Ice Age revealed between the lines, even if it is translated, still makes Hua Feiyu and Qin Feng empathize.

Powerlessness, despair. This is the most direct and most used word for the Ice Age in the book.

Herds of cattle and sheep died, the originally green grasslands were completely covered by snow, and the loss of homes and displacement became the norm for the captives, even the deepest families could only shrink their strength as much as possible to survive this catastrophe, and as for those small and medium-sized nomadic tribes, they could only shiver in the cold and hunger, waiting for death to come.

This is a disaster that is even more severe than the famine, locust plague, and drought in the Central Plains!

"The book is useful, but there are some things that I need to translate further. Since seeing this book, the joy in Hua Feiyu's eyes has not stopped, and she glanced at Ouyang Xun, who was still fighting in the pile of books, and a smile rose on the corner of her mouth.

Until this moment, Ouyang Xun didn't know how much impact what he did would have in the future. He just wanted to do as much as he could, so that Qin Feng, Hua Feiyu and the others could leave a little impression of themselves in their hearts. finally got on his thighs, Ouyang Xun didn't want to live the idle life he had before.

He also has an adventurous and motivated heart!

By the time everyone had searched all the files on the shelves, the sky outside had already darkened. After a rough estimate of the time, Hua Feiyu found that a few people had been here for a whole day.

Fortunately, the information that should be found is basically found, and there is nothing worth cherishing here. Several people began to work on restoring these files to their original state, although these arrangements may be seen through at a glance after the return of Pavilion Master Fan Yang'a, but there is always a glimmer of possibility that they will not be discovered.

Hua Feiyu has now made up his mind, and when he goes out, he will immediately take the cronies who were collected yesterday to Yunzhou with Qin Feng and Li Yanxue, and then the seven sons of Fengyue will converge in one place, and first pacify the invasion of the captives in the south, and then try to do anything else!

After all, Hua Feiyu didn't deal with the Great Wei Dynasty again, she was also a Central Plains person after all, and she couldn't watch the Central Plains land be devastated! The speculation about the reason behind this captive invasion made Hua Feiyu a little uneasy, if the truth was really as she expected, then this captive invasion might not simply end!

Before leaving, Hua Feiyu took one last look at the Book of Wei, and after a long time of entanglement, he still didn't take it away. She had memorized all the contents of it, and it was obvious that Fan Yang'a attached great importance to it in such a conspicuous position that she didn't need to take this risk.

As for "General History of the Northern Regions", it was directly taken away by Hua Feiyu, which is also a helpless thing, after all, she can't memorize it. As for taking it out and copying it again and sending it back, Hua Feiyu didn't think about it in her heart, but now that time is pressing, and this book is extraordinarily thick, she is afraid that it will be too late.

That's right, the current situation in Yunzhou is precarious in her eyes!

Waiting for Hua Feiyu to come out of the secret passage in the rockery, I saw Li Yanxue leading people to wait at the entrance with torches, it seemed that she had been standing here for a day.

Hua Feiyu smiled lightly at Li Yanxue, and then asked softly with a little regret and apologies: "What we have seen is something amazing, and we have no choice but to leave, second sister, are you willing to leave Qingfeng Fuyue Pavilion with us?"

The reason why I say regret and sorry is because Li Yanxue is a martial arts idiot, and the reason why she was willing to join Qingfeng Fuyue Pavilion was because of the countless martial arts cheats treasured in this Heart Washing Pavilion, but she couldn't go back this time.

As soon as these words came out, the secret sentinels behind Li Yanxue all showed different colors, but Li Yanxue's face did not show much surprise.

"Let's go, to be honest, I've been tired of staying here all these years, just blindly cultivating is not a good path, since the eldest sister is leaving, being a younger sister is naturally not leaving. ”

The two girls looked at each other, and they all smiled.
