Demon Slayer: I will play the ancestor of the Flame Pillar

The old man was in a hurry to go to the hospital.

Tokyo.

Asakusa.

Chachamaru's healing house.

Yushiro handed coffee to Tamayo who was working late at night.

"Ms. Tamayo, we have stayed here for too long. We should move out."

Tamayo came back to her senses from her research and yawned a little tiredly.

"Really? It has been several months, but with Lord Rengoku here, we don't have to worry about our safety."

"No, that guy is elusive and can't always protect you, and what I'm worried about is..."

Yushiro shook his head. Although they didn't spend much time together, the girl was very good at socializing with people, and even the ghost who was obsessed with Tamayo was moved.

"I'm worried about Ayami Hoshiko. She's a human, and it's hard to cover up her scent. It'll be troublesome if she's discovered by a ghost."

Tamayo pressed her eyebrows and thought for a while.

"Hoshiko is indeed a good child. I didn't expect that you, Yushiro, still care about her, but in the end, it depends on what she wants."

Yushiro's eyes widened when he heard this.

"Master Tamayo, how can you listen to her? She's very smart, has good hands, and is very diligent in making food for us, but in the end, we can't stay together..."

Knock, knock, knock.

There was a knock on the door outside the house, and the girl's voice sounded.

"Excuse me, is it convenient for me to come in now?"

Yushiro immediately fell silent.

Tamayo looked at him with some doubts, and replied gently.

"Of course, please come in."

Ayami Hoshiko opened the door, jumped in front of Tamayo and stretched out her white arms.

Tamayo looked at her carefully.

"Well, you've recovered very well and are now completely healthy."

Stuck out her tongue, Xingzi was happy for a moment, and then immediately said pitifully.

"Ms. Tamayo, will I have to leave now that I'm better? But I don't want to leave yet?"

The girl tightened the muscles in her arms, trying to make herself look stronger.

"I can help you do a lot of things."

Before Tamayo could speak, Yushiro spoke first.

"No, no, you should leave here when you are fully recovered. We won't keep you here any longer."

"Why? Why do you have to drive me away?"

There was some confusion in Xingzi's eyes, and she sniffed gently.

"Ophiopogon japonicus, Dendrobium officinale, Polygonatum sibiricum, Lycium barbarum, Mulberry fruit, Red spider lily..."

"Ms. Tamayo's pharmacy has these flavors. I come from a family of Chinese medicine and know a lot of secrets that can help you with your current research."

Yushiro widened his eyes in astonishment, while Tamayo's lavender eyes looked directly at the girl, questioning her.

"Xingzi, are you really ready?"

The girl looked at him without flinching, with a firm look in her eyes.

"That's right, Miss Tamayo, I understand everything."

"No, you don't understand anything at all, and we can't take you in here."

Not because he was worried that Tamayo's care would be taken away by someone else, Yushiro was rarely emotional.

"You shouldn't belong here, and..."

"Besides, you are not human?"

The girl raised her eyebrows lightly, and continued to speak calmly in the dull eyes of Yushiro.

"Or is it because you are in danger at any time? You might die suddenly?"

Ayami Hoshiko sighed.

"I have nowhere to go. My family members died of diseases brought by the plague. If it weren't for Brother Tsunesuke, I would have died three months ago."

Her expression was sad.

"Ms. Tamayo, I am mentally prepared, so please stay with me."

"I understand."

Confirming the girl's determination, Tamayo walked up and hugged Hoshiko, and the girl who was still sad just now became happy again.

"Great! Ms. Tamayo agreed!"

She rushed out happily, intending to make some delicious food to reward herself.

The moment the door closed, the girl seemed to suddenly remember something, and turned back and added casually.

"By the way, my physique is special, and I have strong immunity to drugs and poisons, so I can be used for live drug testing..."

After sending the girl away, Yushiro's mouth was still wide open.

"Ah? This?"

Tamayo sighed and turned to Yushiro.

"Like you said, that girl has always been very smart, right? We have lived together for three months..."

Thin

The misty eyes stared at Yushiro, making him feel as if he was the fool.

"Yushiro, since when did you have the illusion that she hadn't discovered your identity?"

Yushiro shook his head.

"Even so, we shouldn't reveal our flaws. In addition to not being able to see the sun, we also endured eating all the food she made.

Tamayo shook her head and chose not to answer the question.

It was poison. The food was mixed with poison that had a slight effect on humans, but it didn't cause any discomfort to the body of the demon.

Hoshiko's pharmacology level was indeed very advanced. She made a test with only some common materials in her hands.

And...

Tamayo's eyes were deep.

Medical family, plague, relatives were all killed, one person wandered, poison, resistance, live experiments...

Although I don't want to guess, the truth behind these clues may not be as simple as the girl said.

Knock, knock, knock.

There was another sound outside the door.
