Datang: My identity as prince was exposed by Li Er

Wait for Li Yi to leave Zhaoxiang Tower.

Ning Ziqi's pretty face turned pale.

She stamped her feet fiercely and gouged Li Yi's back.

Damn straight man!

You really don’t know how to comfort people?

Is this the attitude? Order me?

What should I do to you?!

It seems...he really deserves it.

She was angry, but Li Yi had saved her and her brother, if it hadn't been for Li Yi at that time.

In the Li Yuanying rebellion case, Ning Ziqi may have been killed by Li Shimin.

In other words, her life and her brother's life were both given by Li Yi.

And Li Yi never asked her to repay him.

But even so, you can't speak in a different way?

Qi returned to Qi, Ning Ziqi naturally knew Li Yi's plan.

This era needs to be more stable.

When the Turks were at war, she knew very well that in times of war, people were inferior to animals.

She also wanted to do something for this era.

There are some things that she will not regret even if she wears brocade clothes at night.

In the next two days, Ning Ziqi made arrangements for his brother and asked Li Yi to take care of him.

Alone, holding Li Yi's token, he headed towards Longyou.

The hidden sect of the Tang Dynasty family will be founded by Ning Ziqi!

……

These two days.

Li Yi didn't have any time to spare either.

He found that Tang Hengdao was still slightly inferior in actual combat.

In the last years of Zhenguan, the improved Tang Hengdao came out and caused a sensation in the world.

But before that, the Arabian Damascus knife had already come out.

In terms of actual combat, the Damascus sword of the Arabs is superior to the current Tang Hengdao.

Li Yi learned about the improvement method of Tang Hengdao from Song Yingxing's"Tiangong Kaiwu".

So he spent the past two days improving the smelting of Tang Hengdao.

Although Tang Hengdao at this time was powerful, it had not yet reached the level of a heaven-defying existence that could split armor.

Because Tsuna's willfulness is not strong enough.

It is missing two key core technologies.

One: covered with soil and burned blade.

Second: Baotou.

Covering the earth and burning the blade is, to put it bluntly, a local quenching technology.

The basic method is to cover the parts of the blade that do not require high hardness with prepared soil, and then heat the sword to a specific temperature.

When the red-hot blade enters the water, the naked part cools quickly, while the temperature change of the part covered with soil will not be very obvious, resulting in a different hardness than the unwrapped part.

This can accurately control the different cooling rates during quenching of different parts of the blade. The cooling rate is directly proportional to the hardness and inversely proportional to the toughness.

Steel-clad technology is a knife-making technology invented after in-depth research and understanding of steel.

The main method is to sandwich softer low-carbon steel into the V-shaped hard high-carbon steel; and sandwich steel is to sandwich a piece of high-carbon steel between two layers of low-carbon steel.

Both technologies embody the basic idea of ​​"good steel is used on the blade" to make high-quality swords, and also make the steel sword have excellent toughness.

As a result, the Hengdao became one of the best swords in the world at that time.

After understanding these two core technical principles.

Li Yi began to try to smelt and improve the Tang Hengdao.

Five days later.

The newly improved Tang Hengdao was unearthed.

Will Japanese swords be strong in later generations? powerful!

But if you really want to compare it with the purest Tang Hengdao from 1,300 years ago...it's nothing!

Because all the forging and smelting of Japanese swords are based on the technology of stealing Tang Hengdao.

These are all leftovers from my Han family ancestors’ play, and those that don’t play anymore.

What's more, the smelting technology of Japanese swords has not yet stolen the core of Tang Hengdao.

Early this morning, Li Yi held the newly smelted Tang Dao with a length of about 80 centimeters and fell into deep thought.

There is also a Tang Heng Dao about 1 meter long.

This length was called the Tang sword in later generations of Japan.

Look, what a willful and... ugly naming technique!

These two types of knives have slender blades with slightly curved heads, and the front and back width is no more than two fingers long.

The curves are graceful, just perfect!

Not long after, Di Renjie came over.

Seeing Li Yi's hot eyes, he took a deep breath. hiss!

He quickly said to Shangguan Yi beside him:"The look in my mentor's eyes……"

Shangguan Yi said calmly:"It's obvious that spring is coming."

Di Renjie:"……"

The two walked over.

Then he saw the two Tang Hengdao in Li Yi's hand.

It is different from the previous Tang Dynasty equipped with horizontal swords.

There is an indescribable sense of elegance.

The two of them couldn't help but have hot eyes:"What a delicate knife, so damn handsome!"

Soon.

Hao Chujun and others also came over strangely.

Seeing the excited looks in Li Yi and the other three's eyes, they couldn't help but shudder.

They walked over and then fixed their eyes on the horizontal knife.

"Damn it! What a handsome knife!"

"Under the light, my dog ​​eyes are blinded!"

A few students sighed in admiration.

However, some said with disdain:"Flower display, decoration is okay, but it is useless in actual combat."

Obviously, Li Yifu who spoke is an old man.

The other students nodded in agreement.

This knife... I guess it is for decoration.

……

Li Jing's mansion.

Li Jing cannot sit still and wait for death.

The last time I went to find out what Li Yi meant to Wan'er, I was disturbed by the old man Wei Zheng.

To be honest, Wei Zheng is really shameless.

At first, you said that your Wei family would not marry Li Yi, but now you are licking your face and begging Li Yi.

There is no such thing as this!

Li Jingde had to think of a way to solidify the marriage between Li Yi and Li Wan first.

In this situation, can Li Wan still marry someone else?

The whole of Chang'an knew that the daughter of Li Jing's family was having an affair with Li Yi.

Li Jing simply lost his shame.

Propose marriage!

I took the initiative to propose marriage to Li Yi, this must be done!

Although it is against the rules, the happiness of my daughter's life is important.

Li Jing generally knew Li Yi's identity.

Even if Li Yi is not the eldest son of the royal family, with his status as the richest man in the Tang Dynasty, ordinary gifts may not be available.

You have to find a decent marriage proposal.

What should I give as a gift?

Abruptly.

Li Jing patted his head:"Why did I forget this?"

"Someone, go get me my Damascus knife!"

This is what Li Jing took from an Arab warrior when he destroyed the Eastern Turks.

This kind of knife is very precious.

In the eyes of Arabs, they are all rare and good knives.

Li Jing personally tested it, and in the Tang Dynasty The cross-cutting of the horizontal knife can perfectly cut the Tang Hengdao.

It is such a precious knife.

Li Jing himself occasionally takes it out to pay respects.

Now that he wants to give it to Li Yi, he is really reluctant to part with it.

But for the happiness of his daughter... he will fight.!

With that said, Li Jing took the Damascus knife, wrapped it tightly, and walked toward Li Yi's mansion in a hurry.
