Li You was stunned by Zhu Xufan's question... Xu Yi and Xu Yi's grandfather on the side showed curious expressions.

Then Li You smiled and shook his head: "I really don't know much about this. After all, the Tang Dynasty happened more than a thousand years ago. Our family has no family tree, just ordinary people."

"Then where did you get those jade pendants...!" Zhu Xufan asked curiously.

"Hey...ah...ahy...Old Zhu, you're asking too much...!" Xu Yi's grandfather quickly stopped because the antique shop rules are that the antique shop has been looking at the goods since ancient times and never asks where they come from.

"Haha..." Zhu Xufan bowed and smiled, "Sorry... I was a little curious for a moment... You also know how curious and yearning for the Tang Dynasty. I have seen some time travel and thought about how good it would be for me to travel to the Tang Dynasty."

Li You was slightly surprised, and then he heard Li You ask: "If Mr. Zhu traveled to the 17th year of Zhenguan, how would you change the Tang Dynasty...!"

"The seventeenth year of Zhenguan..." Zhu Xufan looked at Li You and said slightly: "This year was the most painful year for Li Shimin. That year... the chair in the Tai Chi Hall was so tempting.

The story of Li Shimin, Li Jiancheng and Li Yuanji was repeated during the Zhenguan period. The prince Li Chengqian, King of Wei Li Tai, and King of Qi Li You also launched a life-and-death battle to sit on the chair in the middle of the Tai Chi Hall.

Li You was born by Yin Concubine. He was not a legitimate son and was not within the scope of the successor Li Shimin considered. Li You was unwilling to be a vassal king, so he could only follow his father's emperor and also give him a military advise to seize the throne. Li You raised an army in Qizhou, attempting to invade Chang'an and recreate the scene of Xuanwu Gate back then.

But Li You overestimated his strength and was soon defeated and captured. Li You begged his father for his life, but Li Shimin shed tears and gave Li You a complete body. Although Li Shimin demoted Li You to a commoner, he gave Li You a decent funeral because of his father-son relationship.

The rebellion of Li You had not yet subsided, and Hegan Chengji reported that Li Chengqian had rebelled again. Li Shimin sent someone to investigate and cracked the rebellion case of the East Palace. The core members involved in the rebellion case of Li Chengqian were Li Yuanchang, Du He, Zhao Jie, Hou Junji and others.

King Li Yuanchang of Han was the son of Li Yuan and the half-brother of Li Shimin. Du He was Du Ruhui's son and Li Shimin's son-in-law. Du He's wife, Princess Chengyang, was the legitimate princess of Li Shimin and Empress Changsun. Zhao Jie was the son of Princess Changguang and Li Shimin's nephew. Hou Junji was a hero of Lingyan Pavilion and a brother who lived and died with Li Shimin.

The younger brother wants the life of his elder brother Li Shimin, the two elder sons want the life of his father Li Shimin, the son-in-law also wants the life of his father-in-law Li Shimin, and the nephew wants the life of his uncle Li Shimin. At this moment, Li Shimin has truly realized the pain of his father back then.

The more painful Li Yuan was in the ninth year of Wude, the more painful Li Shimin was in the 17th year of Zhenguan. Moreover, no matter how painful Li Shimin was, he had to find a way to clean up the mess. Li Shimin issued an edict, killing his younger brother Li Yuanchang, killing his son-in-law Du He, killing his nephew Zhao Jie, and killing his hero Hou Junji.

Li Chengqian was not Li You, he was the son of Empress Changsun. Li Shimin was reluctant to kill Li Chengqian, and he wanted to protect Li Chengqian and Li Tai. After thinking about it, Li Shimin could only make Li Zhi the crown prince. Li Shimin was not satisfied with Li Zhi, and once had the idea of ​​deposing Li Zhi and replacing Li Ke.

You guys really know how to choose, you will be able to choose this year after you choose."

To be honest, Li You began to admire Mr. Zhu at this time, and immediately pointed out the most important thing in the 17th year of Zhenguan. However, after hearing the latter sentence, Li You really knows how to choose, he smiled helplessly. This is not that he knows how to choose, but that he is unlucky. He travels through this year even though he is still alive.

"Well...!" Zhu Xufan thought for a while and said, "If I traveled through this year, I would definitely offer horseshoes..."

"Horsehoe?" Li You was stunned.

"Haha...I can't imagine it...!" Zhu Xufan smiled and looked at Li You and others, and then said with a proud look: "Horsehoes are said to have been popularized in Rome in the first century BC, and the history of Chinese horseshoes is not found online. Some say it is the Western Han Dynasty, some say it is the Southern and Northern Dynasties, and some say it is the Yuan Dynasty.

So when did horseshoe become popular...?"

"I know this..." Suddenly, Xu Yi on the side smiled and said, "Just a while ago, a rescue archaeological excavation was conducted at a Xianbei site in Kezuozhong Banner, Tongliao City, Inner Mongolia, rare cultural relics such as horseshoe nails were found, providing physical evidence for the earliest use of horseshoe iron in China.

The excavation area was 1,400 square meters, 2 house sites were cleared, and more than 10 ash pits were unearthed, and a batch of pottery, iron, stone tools, animal bones and other relics were unearthed.

This shows that horseshoes were used in the early Xianbei period, so there were horseshoes in the Tang Dynasty. Grandpa, if you offer horseshoes, you will be laughed at by others."

"Is that true... do you all think so?" Zhu Xufan asked as he looked at the other three.

"This...!" Li You and Xu Yi's grandfather looked at each other. Li You was actually confused at this time, because he always thought that horseshoes had begun to be used in the Tang Dynasty. Why do you think so? Because Li You saw that the horses in the Tang Dynasty all had saddles and stirrups.

Li You wanted to become a whole, but he was confused because he had seen the saddle and stirrup with his own eyes, but he had never seen the horseshoe with his own eyes.

Seeing Li You and his old friend not talking, Zhu Xufan said lightly: "I have read the news that Xiaoyi has read, but have you found a problem, that is, the Xiaohuhegele ruins are the ruins of the Xianbei people... In addition to discovering a large number of geometric patterns, archaeologists also have some horse patterns, felt tents and sun patterns, which show the scene of the Xianbei people's nomadic life.

The Xianbei is a major ethnic group in northern China's history and belongs to the Donghu tribe. It was active during the Han, Wei and Jin Dynasties to the Northern Dynasties. The Xianbei people traveled west along the Daxinganling Corridor and established the Northern Wei Dynasty.

But what everyone needs to think about is that in modern times, for example, if something exists, then it will be known quickly through the Internet and media. However, in ancient times, when you invented something, it happened that such a thing was very useful.

In order to enhance their strength, ancient people would keep it secret. The Great Xing'an Mountains were too far from the Central Plains. Indeed, horseshoes had appeared at this time, but as long as the Central Plains did not excavate strong testimony.

Then I can be sure that the Tang Dynasty did not have horseshoes at this time, which is the main reason why the Tang Dynasty consumed a huge number of horses and built so many horse farms, but still wanted to buy horses from the back turtle."

After listening to it, Li You felt that it made sense. The ancient times are different from modern times. If there are any inventions in modern times, they will be advertised immediately through the Internet or media, but the Tang Dynasty is different. Perhaps the nomadic peoples knew the benefits of horseshoe early, but the nomadic peoples who knew the benefits will definitely abide by this secret and prevent the Central Plains from knowing it.

So Zhu Xufan's words were valid. Li You smiled happily, because he seemed to have found a way to give a fatal blow to the turtle.
