Demon Slayer: The man who forged the sword, the blade flows like fire and it scares people to cry.

The knife is pulled out of its scabbard.

The rusty blade has faded in the sun.

But even so,

the masculine aura in the blade body is still endless.

After hundreds of years of dust, the breath is still emanating outward through the show...

This knife is simply an artifact that specializes in killing evil spirits.

Looking at this knife,

a flash of joy flashed in Xin's eyes.

For the problem that the slashing knife could not block the ghost's regenerative ability,

Shinichi suddenly thought of a solution.

If you fuse this knife with the chopping knife ....

However, now facing two problems

, the first is that all the rust on the body of this knife must be cleaned up immediately, so that the original masculinity of this knife can be completely emitted.

However, this grade of knife should be handled very carefully, and the time consumed is not short.

Coupled with the fusion of all the slashing knives, it will be a big project.

The second problem is...

Although this He knife is very strong, there is only one after all.

If this knife is divided equally among all the slashing knives, the power will be greatly reduced.

Village chief: "I believe Mr. Xin Yi can also see that this is a superb knife."

"Originally, Hotaru Izuka planned to sharpen it himself and give it to you,"

I think it's better to show you the knife first, and it's up to you to decide." Tie

Xie Sen: "This grade of knives, just grinding, it takes at least five days, and the middle can not be interrupted." However, the ancestral craft of Hotaru Steel Tsukasa can be completed in three days.

Hotaru nodded again and again and said, "Yes, Mr. Shinichi, give it to me, it can be completed in three days!" Shinichi: "

Thank you, village chief, I need such a knife right now."

"Thank you very much Hotaru-san for your kindness, but....

"Three days, it's still a bit long. "

Three days, among our people, is already the limit..."

Iron Tsuka Hotaru: "Mr. Shinichi, if you polish it yourself, how long will it take?" For

the speed of polishing, Shin Yi was still quite sure in his heart

, because the forging process and speed of the chopping knife itself were much stronger than the Nikkawa knife, and

Shinichi's forging speed doubled in the basic data of the system.

In terms of speed, Shinichi felt that there was no problem.

However, for the grinding stage

, if the speed is increased too quickly, the danger level will increase significantly.

Not to mention the cracking of the knife body, but the heat emitted by the knife body is already a big problem for humans.

After all, during the polishing stage, the hands must always touch the blade.

Wearing protective gear will not work, and if you do that, the finesse and speed of the craft will be lost.

Pay for one's whistle.

At this time, Xin Yi remembered the three breathing methods he had -

[Breath of Flame] [Breath of Embryonic Day] [Breath of Worm] Breath of Worm is

mainly fine.

Although Yanzhi's breath can resist high temperatures in forging, it is too rough for polishing this process.

Then there is only this embryonic version of the breath of the sun....

Xin Yi: "It should take half a day. The

three knife forging men were shocked.

But

everyone was not too surprised

, after all, Xin Yi could forge such a thing as a slashing knife, and the

sharpening speed was five or six times faster, which seemed to be reasonable.

Village chief: "Then it can only be polished by Mr. Xin Yi himself." Tie

Xun Sen: "Half a day is fast, so can the three of us watch Mr. Xin Yi polish?" After

all, it is a top-level sword

, even if it cannot be polished personally, as long as there is a chance to watch, it is also a pleasure for the three of them.

Xin Yi: "Please take care of yourself."

After that, Xin Yi turned around and went back to the room and began to prepare for work.

............

Evening.

The sun is already about to set.

Yiyong had just returned from cultivation.

Recently, he has been cultivating alone on the next mountain, and he is becoming more and more proficient in the control of the slashing knife.

When he stood in the courtyard, he found that there was not a single figure.

Except for Shin Yi's room, which was lit up, there was no movement in the other rooms.

Yiyong

looked around curiously, and then walked to Shinichi's room.

The moment he pushed the door open,

a wave of heat came through the crack in the door.

When

Yiyong walked into the room, he found that the room was full of people.

Everyone huddled in Xin Yi's room to watch Xin Yi sharpen his knife.

Although the room seemed very stuffy, everyone did not pay attention to it, and they still watched very engrossed.

Yiyong

: "You..." Tie Dong Sen: "Shh..." Tie Dong

Sen turned around and interrupted Yi Yong, and put his index finger in front of his mouth, signaling Yi Yong to keep quiet.

Yiyong craned his neck curiously to watch.

The scene in front of him instantly stunned Yiyong...

It turned out that the heat wave in the room came from this knife in Xin's hand....

I saw Xin's hands pressing the knife in his hand, quickly polishing back and forth on the whetstone.

Where the blade was rubbed, it had begun to redden slightly.

Shinichi's speed is fast.

If it weren't for the small range of movement,

everyone would not even be able to see the trajectory of his hands.

Despite the speed, there was no spark where the friction was blowing.

It can be seen that Xin's pair of details such as sharpening angle and strength have been mastered to the extreme.

Although there is no spark,

the red color that is rubbed out does not look like good stubble.

They are ready to move, like trapped beasts, ready to break through the shackles and bite everything at any moment.

Yiyong also quietly joined the observation.

The spirit of everyone in this room is highly concentrated.

Xin Yi has maintained this movement for an afternoon, and the blade body has not changed much.

Others remained in this position and watched for an afternoon.

As the longer I watched, the more engaged my spirit became, and

every "croak" sound made during the sharpening process involved the hearts of everyone present.

Everyone was silent, for fear of making a noise and interfering with Xin Yi's polishing work.

Under the gaze of so many pairs of eyes....

At this time, the blade body finally began to undergo unusual changes.

The reddened part in the middle of the knife body began to grow, and the red color began to spread on the knife body.

This means....

The polishing of this knife entered the final stage.

The range of red is getting bigger and bigger....

More and more wide....

As the flushed red spread to Xin's fingertips....

Yiyong exclaimed: "Be careful!" Yiyong

was worried that Shin Yi was too absorbed and would be burned if he didn't pay attention.

Before the words fell, a powerful aura shook out from Xin Yi's arms.

Everyone was stunned.

I saw Xin's eyes emitting a white glow.

Xin Yi's arms were wrapped in a faint layer of

red, this red was white,

not as bright as the flames,

more like...

This

layer of light red, tightly fitting on Shin Yi's hands.

The originally unbearable red on the knife became extremely docile under Xin Yi's hands.
