Lin Yi picked up the brocade box with both hands and weighed it in his hand.

The weight is not heavy, and it looks like a total of seven or eight pounds.

Take it under the candle flame and take a closer look.

The outside of the box was covered with a layer of black-gold brocade, and it was so old that it turned into ashes when you touched it with your hand.

However, the box itself exudes a faint fragrance, which should be made of sandalwood as the main body of the box for insect prevention.

The brocade box is not locked, and there is no mysterious mechanism.

Lin Yi opened it up and down.

Underneath is a cover with a letter written on a sheepskin.

When I opened it, the text was written in Tang Kai, and the content was related to the "obstacle knife":

According to legend, Ou Yezi, a sword-casting master in the Spring and Autumn Period, stopped casting swords in his later years.

Later generations asked the reason, and Ou Yezi replied: There are too many swords cast in this life, and the killing is too heavy, so the furnace is sealed.

In Ou Yezi's life, except for the two generals and Mo Ye, there were no more apprentices, and the world thought that his ability to forge swords was lost.

Unexpectedly, until the Tang Dynasty, there was a swordsmith named Zhang Yajiu, who had some experience in sword casting.

But he has a strange temper and does not want to make friends with powerful people, so he lives in the mountains all day long, making some farm tools and iron tools.

One day, a fisherman came and said that when he was fishing in the river, he fished up a rusty iron rod and said that he wanted to find Zhang Yajiu to change some farm tools.

When Zhang Yajiu accepted the iron rod and was about to return it to the furnace to be recast, he summoned the "sword spirit" that Ou Yezi had given to him.

It turned out that although Ou Yezi sealed the furnace in his later years, it was a pity that this skill was wasted.

Before his death, he cast the seven famous swords of Tai'a, Longyuan, Gongbu, Zhanlu, Juque, Yugu, and Chunjun, but he failed to make up the full number of ten, and he still had a lot of regrets in his heart.

So he took his favorite piece of material, turned his sword-casting experience into a "sword spirit" and sealed it into it, and threw it into Weishui, so that future generations could know his mind.

After Zhang Yajiu forged this raw material, he cut it into three sections as a preparation material.

The first one that opened the furnace was the Zhou Gong remnant sword that Li Chunfeng took.

As for what conditions Li Gong used in exchange, there is no mention in the parchment scroll.

In the Western Zhou Dynasty, the swords of scholars were mostly decorative and sharp weapons, and the sense of ceremony was greater than practicality.

Zhou Gong's saber was the same, nearly two meters long, and after being taken out by the group of monks, it was cut into several pieces and thrown together with the bronzes in those deep valleys.

All that was left was a hilt and a portion of the blade.

Zhang Yajiu used the raw materials left by Ou Yezi to recast and forge this sword and made it into a "barrier knife".

During the Tang Dynasty, there were four types of swords:

The ceremonial knife is luxuriously decorated, beautiful and generous, and it is an exclusive ceremonial knife for the aristocracy.

The horizontal knife is simple and practical, easy to carry, and is a necessary self-defense weapon for conquest, official business, and travel.

Modao specializes in cavalry, which is extremely powerful, and is an actual combat knife that has been baptized by war.

These three tools require too many raw materials, and only the "obstacle knife" is suitable.

The obstacle knife has the least surviving number of knives in the Tang Dynasty, and there is no accurate specification for its shape.

The archaeological community defines it as the ancestor of the "rib cha" of the two swords worn by the samurai of the Wa Kingdom, the shorter of which is the one.

After casting, Li Chunfeng put the "Barrier Knife" and the "Cloud Seal Heavenly Book" into the stone box and brought them into this sarcophagus.

Lin Yi finished reading the words on the parchment scroll, folded it and put it aside.

Then carefully open the lid of the sandalwood box.

A "barrier knife" lay quietly inside.

The length is less than fifty centimeters, and the handle of the ring head is the same as the saber of the Western Zhou Dynasty and even the Spring and Autumn Period and the Warring States Period, which should be the hilt part of the Zhou Gongdan sword.

The grip is wrapped in cowhide lines, and the blade is made of the same material as the handle.

The shell is made of rosewood, wrapped in copper and pearl rain skin.

Although it is the product of the splicing of two eras, there is no discord at all.

Lin Yi held the barrier knife in the position of the tiger's mouth in both hands, and suddenly felt as if he had traveled through a thousand years of time, and was having a face-to-face conversation with the old people thousands of years ago.

"Cangchang" sounded, like a dragon's groan, and the barrier knife was pulled out by Lin Yi.

After thousands of years, the blade is still as good as new, and the cold light is approaching the door.

There is a blood groove on each side, and the blade has a wavy pattern, and the overall width is almost two fingers, which is the same before and after.

The head of the knife is an obvious Tang knife system, a sharp and hard line, which can be stabbed and chopped.

"Good knives!"

Lin Yi didn't have much contact with knives, but the eldest brother Abu gave him two daggers from southern Xinjiang - Yingjisha.

It is now the product that best represents the hand-forged process.

It's really easy to use, Lin Yi cherishes it very much, and he is reluctant to bring it out this time.

However, compared with the "barrier knife" in his hand, the two Ingisha can only be said to be inferior.

Facing the candlelight, Lin Yi gently stroked the edge of the blade with his fingers.

Suddenly, I only felt that my fingertips were cold, and a few bean-sized beads of blood flowed down the blade, rolled down the blood groove a few times, and disappeared in an instant.

"Is this a confession?"

Legend has it that the magic weapons in this world have personalities, and they cannot be used by people with a temperament.

If it is forcibly controlled, it will be suspected of devouring the master.

As for how to confess the Lord, the simplest thing is to shed blood.

If the master's blood is absorbed by the sword, it proves that the recognition of the master is successful, and this magic weapon will not only not devour the master, but will also accompany the master for life, becoming a sharp weapon for overcoming thorns and thorns.

By the time the blood beads dissipated, the wound on Lin Yi's hand had also healed.

Only a white mark remains.

At this moment, at the junction of the blade and the blade, two engraved seal characters are faintly revealed:

"Kill the Scoundrel!"

Kill the killer, kill also!

瞾 is a word specially coined by Wu Zetian in order to name himself.

It means "the sun and the moon are in the sky, shining on the earth", and it is rumored that "Mingkong" is Wu Zetian's name in Shimen.

This "barrier knife" is named "Killing Grass", and the meaning is simply not too obvious.

It seems that Li Chunfeng was indeed arrogant to himself at the beginning, and told Wu Zetian about this piece of feng shui auspicious soil, which caused Li Tang Jiangshan Society to be ruined in one fell swoop, and regretted it.

It's a pity that Wu Cao's luck was unstoppable at the beginning, and Li Chunfeng could only leave various clues in this auspicious soil, so that future generations could come and reveal the secrets here.

As for Wu Cao's fate, Yuan and Li had already made a conclusion when they deduced it, and after the disciples sorted it out, they named it "Tui Bei Tu".

As for why Wu Zetian did not choose to come here to be buried after his death, but chose to be buried in the Qianling Tomb as the daughter-in-law of the Li family, it is unknown.

In the last few lines of the tortoiseshell "Cloud Seal Heavenly Book", Li Chunfeng wrote the method of cracking the "Three Poison Hides" and pointed out a way to escape from here.
