At that time, there were two methods of steelmaking, one was steel frying and the other was steel pouring.

Fried steel is the most common application, and the steel produced is mostly low carbon steel or wrought iron. Although the impurity content can be reduced after folding and forging (steel making), the hardness of low carbon steel is low. For China at that time, talking about

Not advanced.

Steel filling involves alternately mixing raw and wrought iron, sealing it with mud, and placing it in a furnace for heating. The pig iron's lower melting point is used to infiltrate the molten pig iron into the wrought iron.

Then it is forged and forged to obtain pure quality steel.

If this is true, the Daxia Longque Knife is technically very advanced, and its toughness and hardness will be excellent.

It is not only ahead of other civilizations in the world, but also compared with the swords of the Sui and Tang Dynasties and even the swords of the Ming Dynasty two hundred years later, it does not fall behind in performance.

So whether it is true or not, you will know once you try it!

When Gao Bin and the others came back, they brought a piece of wood from outside.

In order to verify the authenticity of the knife, Gao Bin held the knife with one hand and asked Xu Yuan to hold one end of the wood with both hands and chop it off quickly.

With just one knife, the wood as thick as an adult's calf was cut off in an instant. The section was smooth and there were no burrs at the fracture, indicating that the sharp blade destroyed the structure of the wood in an instant.

Huang Yanyan knows some kung fu, but this knife is enough for her to see clearly:

"What a fast knife!"

Of course, knives forged with modern technology may not be unable to achieve this effect, but in ancient times, it was not easy to have such a sharp knife.

However, the blade is real, but the handle is not necessarily true.

Gao Bin had long discovered the problem with the handle of the knife. It was obviously a later addition. According to the ancient knife forging habits, the handle should be made of wood.

The handle of the knife in front of me actually uses black ivory technology that has been lost since Qianlong, making this knife look not practical, but more like a handicraft.

Is this a later replacement?

What Huang Yanyan is even more curious about is that Helian Bobo's tomb was found locally?

But as the eldest daughter of the Huang family, she had never heard of this matter.

The wolf is a terrifying animal that dominates the grasslands with its alertness, cunning, ferocity, cunning, and bloodthirsty.

Of course, these words are not only used to explain wolves, but can also be used to describe people, especially those emperors who were once arrogant.

Among the emperors of the past dynasties, there are countless clever, treacherous, cruel, cunning and bloodthirsty emperors;

But it is extremely rare to have these wolf qualities integrated into one body.

Helian Bobo, the founder of the Hu Xia Dynasty during the Sixteen Kingdoms period, was such a wolf from the north.

Helian Bobo, formerly known as Liu Bobo, was the son of Liu Weichen, leader of the Xiongnu Tiefu tribe.

The environment filled with smoke and war made Helian Bobo become a man as alert as a wolf at a young age.

In the 16th year of Taiyuan in the Eastern Jin Dynasty, Tuoba Gui attacked and killed Liu Weichen. Helian Bobo successfully got rid of the Northern Wei cavalry with his quick thinking and escaped to Chigangan alone.

Because Tuobagui sent someone to ask for Helian Bobo, Ali, who scolded the cadres, gave him to Gaoping Gong Wuyiyu of the Later Qin Dynasty, and Wuyiyu "gave him a female wife".

After a period of exile, Helian Bobo finally found a place to stay.

When in distress, wolves are best at camouflaging.

During Helian Bobo's stay, he always kept his tail between his legs, and actually won the reputation of being "intelligent in sex and beautiful in manners". Yao Xing, the king of the Later Qin Dynasty, "was surprised when he saw him and paid him deep respect", and not only named him a general of valiant cavalry.

, he was given the title of Captain Che, and was often asked to "participate in military and state affairs".

He Lianbobo was "favored more than honored" and became a rising star in the post-Qin political arena.

As time went by, Helian Bobo showed his wolf tail of "being slow to serve, being crippled by others, being greedy, violent and having no relatives". Yao Xing did not take it seriously, but instead "take Bo Bo as a moral integrity. General Anbei and Duke Wuyuan, together with There are more than 20,000 Xianbei and miscellaneous captives from the three tribes and five tribes, and they are in charge of Shuofang."

A wolf is a wolf after all, and it does not pay attention to repaying kindness.

Without the protection of his father-in-law, Helian Bobo would not have been able to stay away from the pursuit;

Without Yao Xing's favor, Helian Bobo would not have been able to leave the town.

After having an army and a territory, Helianbo's true nature was revealed.

Not long after Helian Bobo arrived at Shuofang, he encountered Xianbei from Hexi Province paying tribute to Yao Xing with eight thousand horses. Helian Bobo did not miss Yao Xing's courtesy to him and forcibly detained the cavalry.

After having the cavalry, Helian Bobo summoned 30,000 troops to attack Gaoping in the name of hunting, killed his father-in-law Wu Yiyu, and reorganized his troops.

A wolf is never familiar with food. It is the nature of the wolf to repay kindness with hatred.

Later, the twenty-seven-year-old Helian Bobo claimed to be the king of heaven, the Great Chanyu, established the Yuan Dynasty, appointed hundreds of officials, the country was named Daxia, and the history was called Huxia.

Usually, when a political power is established, there is often a capital city that symbolizes the foundation of the country.

However, when the generals "admonished the danger", Helian Bobo "disobeyed".

The reason why Helianbobo did not set up a capital city at the beginning was not only because Hu Xia "started a great undertaking but did not have many brigades" and his strength was relatively weak, but also because Helianbobo liked to engage in guerrilla tactics like a wolf.

That is what he said: "Riding on clouds and wind, catching the enemy by surprise. If you are trying to save someone before you hit them, hit them on the back. If you are trying to save them, hit them in front of them."

This strategy of "eating freely" not only strengthened Hu Xia's strength, but also fulfilled Helianbo's wolf ambition.

After the founding of the People's Republic of China, the arrogant Helian Bobo proposed to the bald monarch Li Tan, but was rejected.

In Helian's rage, his wolfish nature aroused and he "led 20,000 men to attack them...killing and wounding more than 10,000 people, plundering 27,000 people, and returning hundreds of thousands of cattle, horses and sheep."

No matter how ferocious the wolf is, it will sometimes give way, but when Helianbobo was injured, his behavior was even more ferocious and terrifying than that of the wolf.

"Lai Tan sent someone who was good at shooting to shoot him, hitting Bo Bo in his left arm. Bo Bo was able to fight back and defeated him. He chased him for more than eighty miles and killed tens of thousands of people."

Helian Bobo can be regarded as the most powerful general during the Five Husties period.

There must be many treasures hidden in his tomb. As a member of the Huang family, it is impossible for Huang Yanyan not to be interested.

But when Gao Bin removed the handle of the knife and poured out the 'Tianqi Tongbao' inside, Huang Yanyan finally put away his interest in the treasure and turned to look at the 'Tianqi Tongbao'.

"This is most likely a clue left by Uncle Xu." Gao Bin said decisively.

"But what's the use of this? What does father want to tell us by leaving this?" Xu Yuan was puzzled.

"I don't know either. By the way, didn't you leave any clues in your Sudinglu?" Gao Bin suddenly mentioned, thinking of Wei Academy.

"Su Ding Lu?" Xu Yuan was stunned for a moment, then took out the family secret book from his arms and looked through it.

After reading it for a while, I suddenly realized that this was not good, so I put the book down:

"Let's watch it together?"

Huang Yanyan asked:

"It's not good. After all, it's something passed down from your ancestors. What if we learn it."

Make a wish and shake your head with a smile:

"Don't worry, it's all passwords. No one can understand it except me."

When Gao Bin mentioned Su Ding Lu, he certainly wasn't trying to steal his master's skills. With Da Jin Ya's knowledge reserve, he was enough to do well in this industry.

His purpose is to lead out of the academy.

No, after reading for a while, he pointed to the preface and said:
Chapter completed!
