Where should I go after being transported to Demon Slayer?

Is there something I've forgotten?

Why can't I remember?

A single sentence awakened him from his reverie: for Shinobu, that Nichirin Blade was indispensable.

Tianyi sighed deeply. It seemed he would have to go to the lord's place tomorrow morning.

It's time to draw a picture of Shinobu, otherwise it will be difficult to explain to the lord.

Life is tough, Tianyi has to make a living by performing.

The tsuba (handguard) resembles a butterfly with outstretched wings, making it very beautiful. The hilt is mint green with copper accents, and the blade is only sharpened at the head and tail, with a spine running through the middle.

The back blade is barbed, which is also where poison is hidden.

This very unique design not only reduces the weight of the knife but also maintains its balance, preventing it from being front-heavy and back-light.

(I'm sorry, I'm not good at loading images!)

Uchiha Tenichi wrote it all down in one go.

As for the scabbard, I remember that it could also be used to make poison, although only 50mg of poison was used. But the real trick was in the scabbard; when the knife was put back into the scabbard, the poison formula would change.

Tianyi looked at the paper, which was covered with densely packed words.

"My dear wife, this is all I can do to help you. The rest is up to you."

.........

the next morning

"Feng" Tianyi whispered to his capable assistant, "I must send it to deliver a message to my lord."

A crow flew down from the tree. (Hey, hey, hey, I'm not a crow, okay? I'm a harlequin crow, if you can't say it, then don't.) "Tianyi, what do you want? I'm still sleeping!"

"Feng, go tell the lord that I'm coming to visit him this morning. I have something to tell him. You can go now!" Tianyi watched Feng fly away and gave a satisfied smile.

"Tianyi, come and eat quickly, or these three gluttons will eat it all up." Hearing Lianyu Liuhuo's call, Tianyi looked at his familiar and cozy home and smiled.

"Leave some for me, I need to go see the lord today, I have some things to ask him." The four looked puzzled upon hearing Uchiha Tenichi's words.

Makijuro was the first to ask, "What are you doing going to the lord's place? Is there something important?"

Tianyi shook his head helplessly. It's alright to go to the lord's place for his wife, even if he gets lost!

"Don't worry, everyone. I'll be back soon. I'm not staying at the lord's place. This is my home, after all!" Uchiha Tenichi said, holding a few autumn cakes in his hand and eating them as he walked.

Arriving at the door, he looked left and right, as if searching for something.

"Hehehe, Lord Tianyi has given permission, hurry up and come with me."

It took about half an hour to walk.

Tianyi stood at a distance, looking at the big house.

This is something I couldn't afford before. After coming into this world, I feel much more relaxed. The people I feel most sorry for are my parents, who died without a word.

Uchiha Tenichi gently opened the door and stepped into the room. Seeing the young man whose forehead was already turning purple, Uchiha Tenichi quickly stepped forward and knelt on one knee. "Good morning, my lord."

"Oh, it's Tianyi! Get up quickly. Didn't I tell you before? You don't actually need to kneel before me. Is there something you want to tell me?" Uchiha Tianyi didn't reply, but just quietly looked at his lord.

"My lord, you have sacrificed so much for the Demon Slayer Corps. What's wrong with me kneeling?" Upon hearing this, Kagaya Ubuyashiki revealed a satisfied smile.

Uchiha Tenichi handed over the blueprints from his pocket. "This is a Nichirin Blade designed for Shinobu Kocho. Since she doesn't have much strength, she can only use poison. Please grant me permission, my lord."

Kagaya Ubuyashiki didn't speak, but simply looked at Tenichi Uchiha and smiled. "I know, Tenichi, you like Shinobu, don't you!"

Upon hearing this question, Tenichi quickly replied, "Lord Zhou Gong does indeed like you, but we've already started dating." Ubuyashiki Kagaya smiled contentedly upon hearing this answer.

"So you two were already dating! I had no idea, hahaha!"

"My lord, what is wrong with your illness?" Ubuyashiki Kagaya asked, explaining the situation.

"Because their family is related to Muzan Kibutsuji by blood, and Muzan Kibutsuji became the Demon Queen, the Ubuyashiki family was cursed, and all of them were weak and sickly, and would die young. In order to prevent their bloodline from dying out, the Ubuyashiki family followed the advice of the shrine master and married girls from the priest family every generation. Although they continued the lives of their descendants in this way, no one could live to the age of thirty."

Suddenly a crow flew in, and Kagaya Ubuyashiki handed over the blueprints. The crow grabbed the blueprints and flew away.

"Tenichi, the swordsmith will come to find you after half a month." Upon hearing this, Uchiha Tenichi nodded repeatedly.

"My lord, I shall take my leave now."

"Go, Tianyi."

Upon hearing this, Uchiha Tenichi's heart trembled. "My lord, I can actually heal you."

"Next time, Tenichi, you should go find Shinobu Kocho. She's still practicing her swordsmanship there!"

This time, Uchiha Tenichi didn't respond; he simply walked out alone.

He walked slowly towards the Butterfly Mansion alone, looking up at the sky, which was very blue and beautiful, but a few years later, the lord would never be able to see him again.
