After explaining that Yaoya Yashiki was going to ask for the recipe for the medicine from the mouth of Onimai Tsuji, Emiya found himself idle in the world of Demon Slayer.

Six of the winds were killed by Emiya, and five were killed.

Ghost Dance Tsuji is miserable and hides again, and he can't find his whereabouts for a while when he guards the palace, so he can only hand it over to the ghost killing team.

But the current Demon Slayer team doesn't seem to be able to find the whereabouts of Onimai Tsuji.

So Emiya decided to leave the Demon Slayer Blade world and explore a new world.

But before that, he first went to the Earth Error World to see how the members of the Ghost Slayer Team lived in this Earth Error World.

The Guard came to the Hephaestus family and learned from Hephaestus that the members of the Demon Slayer had been immersed in adventure every day since they arrived in Olari.

Departing in the morning and coming back in the evening, you spend at least half of the day in the dungeon.

The reason is simple, because they are here to increase their strength.

Hephaestus had no choice but to go with them, but she asked her family's blacksmiths to build some powerful armor for the members of the Demon Slayer.

These armors can protect their lives in critical situations.

The current members of the ghost killing team are rapidly improving their strength.

As for the knife forgers, after joining Hephaestus's family, they are currently learning some high-end forging techniques, and when they combine these skills with their own abilities, there will inevitably be a big explosion.

Even Tsubaki, the leader of the Hephaestus clan, is very much looking forward to the future performance of this group of knife forgers.

"Looks like you're very satisfied with these knife forgers." Emiya said as he drank his tea.

"That's right." Hephaestus nodded and said with a smile: "Tsubaki and I are very much looking forward to the future of these people, who will definitely become the mainstay of our family. If you meet such a good blacksmith in other worlds in the future, don't forget to tell me. ”

"No problem." Wei Gong readily agreed. Then he took out two letters from his pocket and handed them to Hephaestus, "This is a letter written by Yaoya Sanyashiki, the envelope is for you, and the share is for the members of the Demon Slayer Team." ”

Hephaestus took the letter and put it aside, "I know, I'll give it to them when they get back." ”

Emiya smiled, drank his cup of black tea, and got up to say goodbye to Hephaestus.

Hephaestus didn't keep it, and after sending him away, he picked up a copy of the letter that was written on it by the gods himself, opened it, took out the letter inside, and read it.

And after leaving the Hephaestus family, the palace came to the Mich family.

The Mihe family ran a small Azure pharmacy, and when Wei Gong walked in from the main entrance, he saw a listless, sleepy girl lying on the counter.

The girl heard the footsteps and straightened up suddenly, "Welcome." ”

Emiya looked at the girl, the girl's right arm was a prosthetic, and she should be Naza Elisis, who caused the Mihe family to almost fall apart.

Emiya remembered that she seemed to like Mihe, but Mihe didn't notice it.

"What do you want?" Although the scale of our Azure Pharmacy is very small, the elixir made is quite good," Nazha began to sell the Elixir of Azure Pharmacy to the Guard.

Emiya smiled and said, "Hello, I'm looking for Tanjiro Kamado." ”

Nazha couldn't help but be stunned, and looked Wei Gong up and down a few times, "Who are you and what do you have to do with Tanjiro?" ”

"Sort of a friend."

Nazha suddenly thought of something and blurted out, "You are the benefactor in Tanjiro's mouth." ”

"Benefactor?" Emiya said, "I don't feel like I'm a good friend to Tanjiro, because I think we're just a fair deal. ”

Nazha said, "But Tanjiro sees you as a great benefactor. ”

"That's probably because Tanjiro is very gentle."

"That's just as well." Nazha smiled and said, "Tanjiro is indeed a very gentle person, but it is unfortunate that you are here, Tanjiro is now on an adventure in the dungeon. ”

"Then I'll find your beans in the stove, is she there?" Emiya retreated to the next best thing.

"Unfortunately, You Bean and Tanjiro have gone on an adventure in the dungeon." Nazha said with a wry smile.

Wei Gong sighed, this is really unfortunate, "Okay, then I'll find Butterfly Shinobi, he should be there." ”

"You don't even know Shinobi?"

"Sort of a friend."

"If you endure it, you can also start in the dungeon, and Tanjiro, and your beans."

Wei Gong rubbed his temples, "Butterfly can't bear to learn pharmacology knowledge, what are you going to do in the dungeon?" "The reason why she was introduced to join the Mihe family in the first place was not to let Butterfly Shinobi learn medical skills?

Nazha said, "Shinobu went to the dungeon to find some special medicinal herbs. ”

Wei Gong was stunned, and couldn't help but suddenly realize, "That's the case, then do you know where she went?" ”

"With the strength of Shinobi, it should be around the tenth layer."

"Okay, then I'll go find them." Wei Gong directly pushed open the space door, and under Nazha's surprised gaze, he arrived at the tenth floor of the dungeon from the Azure Pharmacy.

Emiya went around in circles on the tenth floor, killed a group of monsters, and did not find Butterfly Shinobu on the tenth floor.

Could it be that he has already entered the tenth floor?

Wei Gong thought so, entered the tenth floor, and after turning around, he still didn't find the butterfly ninja them.

So he went down.

Twelve, thirteen, fourteen, fifteen...... Weigong Lu broke through to the seventeenth floor, killed hundreds of monsters, and the devoured life force was full again.

But he still hasn't found Butterfly Shinobi.

Could it be that he was wrong, Butterfly Shinobu had not yet entered the tenth layer at this time, but was above the ninth layer.

So he went back from the seventeenth floor, and when he came to the seventh floor, he found Tanjiro Kamado and Kamado Bean, who were fighting with the spider monsters.

At this time, the stove door has already taken off the bamboo tube in its mouth, and jumps sideways on the left and right of the spider monster, and can kick the spider monster to death with his feet.

"Ernie sauce, leave it to me here." Kamado Beans protect Tanjiro's back, so that Tanjiro Kamado can rest assured that the enemy in front of him is not worried about being attacked by monsters behind.

Because his sister is protecting him.

With his sister's protection, Tanjiro Kamado is full of energy, and the Hinawa knife in his hand cooperates with the breath of water, and he can easily cut off the head of a spider monster with each knife.

This strength ...... Yes.

Emiya can see that the current Tanjiro Kamado should maintain the state of the complete works and the constant state, and the strength is very good.

But what's even more powerful is his sister Kamado You Douzi, whose strength is still above Tanjiro.

The strength is no longer inferior to the lower string ghost.

This Nima is very powerful.

And it seems that Kamado You Beans has regained her senses, and she speaks clearly and methodically.

Mihe is worthy of being a god of medicine, but there is a way.

After the two of them had killed all of the spider monsters, Emiya walked over, "Also, Tanjiro Kamado." ”

"Wei ...... Emiya-sama. ”

Tanjiro Kamado was also very surprised to see Emiya, put his sword into the sheath, saluted Emiya, and asked, "Did Lord Emiya also come to the dungeon to practice?" ”

The stove door on the side of the door You Douzi also hurriedly saluted, she can remember that she can recover, it all depends on the benefactor in front of her.

"No, I'm here for you."

Wei Gong took out another letter from his pocket, "I went to the Azure Pharmacy, but you weren't there, so I came here to look for you, this is a letter that your master Scales Zuo wrote to you recently, take it." ”

"Master......" Tanjiro Kamado took the letter with both hands, his face excited. He didn't expect that after coming to this world, he would still receive a letter from his master.

Wei Gong asked: "I gave the letter to you, you can read it at any time, by the way, what about Butterfly Shinobi, didn't she follow you?" ”

"Lord Wormpillar is gathering herbs nearby." Tanjiro Kamado said.

Emiya couldn't help laughing, "It looks like you already know the identity of Butterfly Shinobi." ”

If you think about it, both of them are holding a Hinawa knife, and you can understand each other's identities just by looking at them.

Tanjiro Kamado said, "When I first met Lord Worm Pillar, I was also shocked, I didn't expect that so many people from the Demon Slayer Team would come to Olari. ”

"Alright, take me to find Butterfly Shinobi."

Tanjiro Kamado nodded, "Please come with me, Emiya-sama." ”

Under the leadership of Tanjiro Kamado, Emiya soon found Butterfly Shinobi, who was collecting herbs.

"Ahh Butterfly Shinobu was also a little surprised when he saw Wei Gong, and said lightly.

"It's not an accident." Wei Gong took out a letter again, "This is a letter from your lord-in-law, take it." ”

"My lord's letter to me?" Butterfly Shinobu was surprised and reached out to take the letter.

Wei Gong said: "Okay, since the letters are all for you, I will go first, I wish you a good time." ”

The reason why he came to the wrong world this time was because he was got rid of Yaoya by Sanyashiki and came to deliver the letter.

Hephaestus Seal, Ghost Slayer Seal, and Butterfly Ninja Seal.

After seeing this situation recently, Tsutaki also wrote a letter and asked Emiya to hand it over to Tanjiro Kamado.

Wei Gong felt that this was just a gesture, so he simply agreed.

Now, he has handed over all the letters, and after saying goodbye to Butterfly Shinobi, Tanjiro Kamado, and Kamado Bean, Emiya left the dungeon and returned to the surface.

After that, Wei Gong went to the Pavilion of Dusk again and found Loki.

"Yo, Loki."

When Loki saw Wei Gong, he ran over like a gust of wind, grabbed Wei Gong's collar, and shook it vigorously, "You guy, you still have the face to see me?" ”

Emiya was dizzy and quickly broke free from Loki's clutches.

"What are you crazy about, Loki." He said dissatisfied.
