Next, Liu Zhenhe referred to oracle bone inscriptions, gold inscriptions, and pictographs, combined with the "Historical Records. Xia Ben Ji, "Bamboo Book Chronicle. Xia Hou's Clan, Imperial Century. The third (Xia)" and other historical documents record the historical materials of the Xia Dynasty.

Liu Zhenhe read out more of the inscription on the inner wall of 'Yiqipan'.

This is an inscription of praise.

In the inscriptions, the exploits of Dayu are praised: "control the flood and stabilize the world", "conquer the three seedlings", "formulate the calendar, guide agricultural production", and "divide the country into Kyushu".

Qi's exploits: Tong Guò conquered Boyi, the leader of the Dongyi tribe by force, defeated him and succeeded to the throne, and defeated the powerful Youhu clan in the Battle of Tong Guò, which allowed the Xia Dynasty to be consolidated

There is a paragraph of text under the picture of 'Yiqipan', which occupies half a sheet of paper, about hundreds of words, and the text tells that Chen Rui has made a detailed and detailed summary and analysis of the study of 'Yiqipan'.

The text says: Yiqi Pan was cast during the reign of Xia Chu, and it was cast by a person named Yiqi who was the Taishi Ling in the Xia Dynasty, so I call it Yiqi Pan.

First of all, Chen Rui told the origin of Yi Qipan's name, and then entered the main text.

Through the research of Guò Yiqipan, we can understand at least three aspects of the history and social life of the Xia Dynasty.

First, the Xia Dynasty had a mature and progressive writing.

Second, the Xia Dynasty had advanced bronze smelting technology and bronze casting technology.

Third, the Xia Dynasty was a very unified tribal federation state.

Chen Rui used three all-round pictures of the front, inner wall and bottom of the Yiqi plate and a text summary and analysis of the Yiqi plate. To argue that at the beginning of the paper, Chen Ruiming Zong Kaiyi put forward an argument that 'the Xia Dynasty was in existence, I have no doubt about this. The Xia Dynasty has crossed the threshold of civilization, and I am very sure of that. ’

There is also a text below. In the text, Chen Rui gives a complete genealogy map of the Xia Dynasty and tells the historical events that occurred in the Xia Dynasty in the form of a list.

Liu Zhenhe looked at the three clear pictures of the front, inner wall and bottom of Yiqipan on the manuscript in his hand and the text summary and analysis of Yiqipan by the contributor below the picture.

Liu Zhenhe expressed his affirmation.

The picture of Yiqipan is very clear, and the summary and analysis of Yiqipan are very in place, meticulous and reasonable.

If you can be sure that the Yiqi disk on the picture is real.

Then it can be proved with great certainty and certainty that 'the Xia Dynasty is a zài, and the Xia Dynasty has entered the threshold of civilization.

These two issues have always been very controversial in the international and domestic academic circles.

Thinking of this, Liu Zhen and his chest almost exploded, and he couldn't suppress the excitement in his heart.

The hand holding the manuscript was too excited, and some of them trembled.

A thin, wrinkled face showed an expression of ecstasy.

At this time, one of his students happened to pass by his office. Seeing Liu Zhen sitting in the office through the glass window of the office and his expression at this time, he must be very surprised.

To know. Liu Zhenhe has always given people the impression of a steady, very strict person.

His students rarely see the expression on his face, and in the eyes of his students it is a poker face.

Yi Qipan brought Liu Zhenhe a very big surprise.

Liu Zhenhe is very much looking forward to what he will see in the manuscript of the paper next.

Liu Zhenhe turned the next page of the paper with anticipation.

A bronze sword came into his eyes.

The bronze sword is smooth and shiny, finely organized, and has no trachoma. The blade is thin and sharp, and the cold light is shining.

Liu Zhenhe's eyes couldn't help but close, this was an extremely sharp bronze sword, so dazzling that people didn't dare to look directly at its blade.

A bronze sword has survived thousands of years without rust, which is a miracle, and it also shows that the Xia Dynasty had a very high bronze smelting technology on the side.

Liu Zhenhe found a string of inscriptions near the hilt of the sword, which read: Inherit the mandate of heaven, the world is Xian Dynasty.

The eight-character inscription vividly reflects the royal momentum and hegemonic ambition of an emperor.

"This is a real sword of the emperor." Liu Zhenhe said with some feelings.

'Sword of the Emperor' can be redefined.

In ancient China, there was a saying that there were ten famous swords.

The sword of the Holy Dao, the sword of Xuanyuan Xia Yu.

The Sword of Benevolence. Zhanlu.

The sword of the emperor, Chixiao.

Sword of Might, Taia.

The sword of integrity and purity. Seven Star Dragon Abyss.

The sword of love, the cadre, the evil.

The sword of bravery, the intestines of the fish.

The peerless sword of honor, pure jun.

Ten famous swords, each sword tells a story, and each sword represents a good quality of the Chinese.

The Sword of the Emperor. The Chixiao Sword can be replaced with this bronze sword, which is more suitable for the name Emperor Sword than the Chixiao Sword.

The Chixiao Sword is compared to this bronze sword. One notch worse.

There is a text below the bronze sword picture.

Qi sword, Xia Yuzi Emperor Qi to Gengxu eight years cast, 89.7 cm long.

There are few words, less than 20 words, but they are concisely summarized.

First, the name of the bronze sword is introduced, and when it was cast.

Second, focus on the length of the bronze sword, which is 89.7 centimeters.

Why did Chen Rui focus on the length of this bronze sword here?

Outsiders may not understand, you introduce a sword, important such as the sword ornaments, ornaments, inlaid gems you don't say, you have to focus on the length of the bronze sword, this is not to grasp the point, to say that you can't describe it.

However, Liu Zhenhe understood very well that Chen Rui would focus on the meaning of the length of this bronze sword here.

This length is quite remarkable in the Xia Dynasty.

It is well known that in the Bronze Age, the key to sword casting was how much tin was added to the copper during smelting.

There is less tin, and the sword is too soft; There is a lot of tin, and the sword is hard and easy to break.

Therefore, in the bronze swords of the Shang Dynasty found in archaeology, their sword bodies are generally very short, only twenty or thirty centimeters, and the production zuò is also relatively rough.

Until the Qin Dynasty, the length of the Qin sword in Guanzhong reached 80 centimeters, and the longest could reach 95 centimeters.

The Qijian is 89.7 centimeters, nearly 90 centimeters, and its copper-tin ratio makes the hardness and toughness of the bronze sword just right.

The length of the tong guò qi sword can show that the bronze smelting technology at that time in the Xia Dynasty had developed to a very mature and advanced Cheng dù.

From the casting years.

Sharp edges.

This is a sword of the emperor.

And through the sword, travel through time and space, return to the Xia Dynasty copper casting workshop more than 4,000 years ago, and personally feel that the Xia Dynasty has been very mature, advanced bronze smelting technology and exquisite bronze sword casting technology.

Based on these four aspects, Liu Zhenhe believes that it is not an exaggeration to call 'Qijian' the first sword in China.

Xuanyuan Xia Yu Sword, which is more qualified to become the first sword in China than Qi Jian, this sword is a legendary thing and cannot be taken seriously. (To be continued)
