Chen Yu didn't give me time to think about the problem, and she didn't want to answer, but continued to talk on her own.

"It's another year since the Prince of Khotan was exposed to wind and sand, so he had no choice but to go to Hujiangu City to take refuge. As a result, he found that the capital of Xiye Kingdom had become a hell on earth.

"The Prince of Khotan escaped from Xiye and submitted a letter to the Protectorate's Mansion. The new Protector Chai Zhewei was about to find someone to establish his authority, so he gathered the coalition forces and led the army to the south. After a night of besieging the city, the people of Xiye disappeared.

"This is the last trace of Xiye Kingdom in history. Since then, the Shule people of the Yue clan occupied this land. Xiye was completely renamed Zhujubo Kingdom. The land is still there, but it has nothing to do with the Xiye people of the original Di Qiang tribe.

"We might as well call this long thousand years the "absent period". During the entire absent thousand years, the land in the Western Regions experienced the rule of the Tubo people, Uighurs, and Mongols, and finally reopened Xinjiang and established a province during the Qing Dynasty.

"During the Republic of China, Western explorers like Stein and Heding went deep into Xinjiang again and again. They discovered many ancient cities in the Western Regions and dug and stole many cultural relics, but still did not find any traces of Hujiangu City, the capital of Xiye Kingdom.

"So, three questions were left behind during the absence period, that is, where did the people of Xiye go? If they were really buried by sandstorms, why would the mountain mandibular appear after a thousand years? And why are other ancient cities in the Western Regions gradually discovered, but the Hujiangu, a big city, no one knows all year round?"

"This...is the reason for geomagnetic?" I couldn't help but say.

"Why don't you talk?"

"No, no, Teacher Shen, please continue, I'll listen to the class carefully."

Chen Yu stretched out his little finger and pointed at the soda water on the table, and I quickly brought it to her.

"Teacher Shen, please use tea."

"You can sit down."

"You are a person with diligent legs and feet, excellent memory, and a lot of brains now. Thanks to your struggles these days, we have figured out the specific year of the absence period, that is, from the first year of Yonghui in the Tang Dynasty (650) to the reappearance of the faceless man this year, a total of 1366 years.

"However, although this period is called the absence period, there are actually some traces vaguely, such as the origin of the Wei family in Yuntang. According to Wei Laokun, the Wei family in Yuntang came from Yuanmao Mountain in Gansu, and their ancestors were cave dwellers. As for why they didn't go down the mountain, it was because there was a circulating ancestral teaching, that is, the cave dwellers were scouts of the gods, that is, the people who kept watch over the gods.

"And a few days ago, when you and Hualien were traveling through the desert, they accidentally encountered the real Hujiangu City, where two wrong locations appeared, one was in Yuanmao Mountain and the other was in Yuhan, Gansu. If you look at the map, Yuanmao Mountain and Yuhan happened to be stuck on both sides of the narrow Hexi Corridor. It seems that the so-called scout is the place where Xiye Kingdom sent to see the military information in the east.

"When did the cave dwellers stay in Yuanmao Mountain? Wei Lao Kun didn't know, so we didn't know even more. However, during the Yongle period of the Ming Dynasty, the cave dwellers were exterminated by the Ming army. The escaped Duke Shiyuan was abducted and came to the Wei Yangan family. Later, the ancestors passed down from generation to generation, but there were often fish-faced men with abnormal appearance and certain supernatural powers in the bloodline of the legitimate relatives, and Wei Lao Kun was one of them.

"As for the reason why they became faceless men, Wei Lao Kun was because of three ‘Pearls’. He was unwilling to let Mingzhu bring disaster to his descendants. He participated in the design of the tomb of King Luqiu, the younger brother of King Huai, and made a ‘tomb in the tomb’, sealing himself and the three pearls at the bottom.

"We have been to Wei Lao Kun's residence. There are white grass and some products growing everywhere under the ground dozens of meters deep. These have allowed Wei Lao Kun to live underground for more than 400 years. After Wei Lao Kun's death, the Wei family still did not escape the misfortune of gene mutations. The recent fish-faced boy with a gene mutation is Wei Zanxin, the grandson of Wei Shengchuan and Wei Yanxin's son.

"There is an inexplicable Spring Festival couplet in the old house of Wei, which says, "Thousands of times, the wind blows the green willows, and a drizzle moistens the red lotus." There are many secret words in this house. According to Wei Lao Kun, it is said that it has been digging since the first generation of Wei Shiyuan, with the purpose of giving the Wei family a strange appearance and cannot accommodate the fish-faced descendants in the world.

"Wei Zanxin hid in the secret passage and later disappeared for no reason. Later, the child appeared in Qujiang and Guzhong case. According to the visitor from Hell, the faceless man surrounded him and was very respectful to him. According to the documents of the "Science Society" puzzle solving, he was actually a descendant of Master Xiye and was found by the Morro Sect to be a "saint child".

"In this way, we understand that in the 'absence period', there was actually a group of Xiye people, who were probably descendants of the national teacher. They left the Western Regions and came to the easternmost end of the Hexi Corridor - and further east, the Guanzhong Plain, the hinterland of the Tang Dynasty. These people chose two mountains in the Hexi Corridor and lived there. They took the task of scouts to help Xiye people see the movements in the Central Plains.

"After generation after generation, because there is no writing, the one among the cave dwellers has disappeared, and the one in Yuanmao Mountain has gradually forgotten its mission. They have passed on history through songs and survived on the desolate mountain top with three pearls.

"These people later came to Weiyang and settled in Yuntang. Therefore, the Wei family should be the only descendant of the people of Xiye who live in the secular world."

I kept nodding, Shen Yu was right. She said two days ago that she felt that her abilities were gradually recovering. Did she find that the ability of the "logical singularity" had returned?

"I finally finished talking about history. Now it's time to talk about what happened later." Shen Yu said in a long sigh, "Look at this time. After the talk is over, we should also go to Luqiao Park to see the rally."

"It's time to talk about this year, right?" I asked.

"Of course not. I just talked about the chronicles of the Wei family, and I want to talk about the history of another family."

"Who's home?"

"The other branch of the descendants of Xiye - Wen Jia."

"Wen Tingxu? What does his family's history have to do with Xiye? His grandfather was from Changbai Mountain in the northeast. He followed the Fourth Field Army to Central and South China, and finally stayed in Weiyang. The place in Changbai Mountain is related to the bronze gate, and it is thousands of miles away from Xiye, but it is impossible to fight."

"No, you still remember, Wen Tingxu said that his grandfather once remembered a song."

"Remember, remember, it's called 'The foot is waving the sword dog, and the head is in Weiyang City. Weiyang settles his home, and wants to go quickly', right?" I asked.

"Your memory is really not something you can see." Shen Yu said admiringly, "Then I ask you, what does wielding a sword mean? Does it mean wielding a sword and cutting off the dog's head?"

"It's certainly not. According to the parallelism of the following sentence, the sword-waving dog should be a place name - but I have never heard of this weird place."
