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

The owl in the sky circled back and forth, and finally landed on Lin Heng's shoulder, stretched out its claws and handed over three test tubes. "Is the first phase of the human transformation medicine finally completed?" Staring at the light blue potion in his hand, Lin Heng was eager to try it. The progress of the medicine was slightly faster than the original work. After all, the three people developed it together and collected the blood of Muzan and himself. "Gu, gu." "Is it still a little defective, but it doesn't matter. Next, we need to focus on other things." Lin Heng took out a piece of paper and started writing. "Ms. Tamayo, congratulations on your successful production of the first-stage human transformation potion. Now it's time to fulfill your promise.

I need you to make a potion that can allow demons to survive in the sun before the final battle with Muzan.

As for the raw materials, the blue red spider lily that Muzan is looking for only blooms during the day. I guess Nezuko has eaten it. Please search in the Kumo-tori area.

Attached are my three tubes of blood."

Expertly drawing out four tubes of blood, Lin Heng tied them to the owl.

"Gugu, go find Caijian Xingzi first."

Waving his hand and looking at the owl flapping its wings, Lin Heng's eyes darkened.

"Tell her to be safe..."

Demon Slayer Corps Headquarters.

Rock Pillar Training Ground.

"Okay, I'm so tired, Tanjiro."

With his eyes rolled up, Agatsuma Zenitsu lay on the big rock, and tears could not stop pouring out.

"I'm really going to die if I practice like this day and night! Tanjiro!!"

"You're so long-winded, Manjiro has already mastered the pattern and even pushed a big rock."

After walking out of the freezing cold stream, Zhuzhu kept chanting Buddhist scriptures.

"Namo Amitabha, Namo Amitabha..."

"Inosuke, please don't say that about Zenitsu, I'm almost at my limit." Tanjiro had big dark circles under his eyes and a dead look on his face.

Because Lin Heng told them to take special care of them, the pillars all increased their strength.

After passing through Tengen's physical training, Mitsuri's flexibility training, and the eldest brother's combat awareness training, etc.

They met that man.

The wind pillar, Fushigawa Shima, who also had heavy dark circles under his eyes and a dead look on his face, suddenly became excited.

"Since you are all so strong, why don't you come together to participate in the evening's anti-pillar training! That's it!" He said so.

So the nightmare began...

At midnight, there was a rumble in the backyard of the Demon Slayer Corps.

The three little ones were terrified and trembling as they saw the pillars with the activated patterns being beaten to pieces.

The culprit, Lin Heng, didn't even breathe, but walked up to them and smiled kindly.

"It's your turn next..."

As long as you don't die from training, you will train to death.

Under such high-intensity pressure, the three little ones burst out with potential, and their strength has improved by leaps and bounds.

"Tanjiro, Zenitsu, Inosuke, the training of the three of you will be temporarily suspended."

A steady voice sounded, and the tall Gyoumei led a few people to the shore slowly.

"An emergency has occurred. The enemy has been discovered in the Swordsmith Village. Muzan may choose to attack there."

Hyoumei turned sideways and let the people behind him go.

"The idle pillars have been dispatched. I will be in charge of the headquarters. Now we will rest until the evening. You will set off together at midnight."

"Is it the village of swordsmiths? Tanjiro's sword is broken." Zenitsu looked saved.

Tanjiro looked at the few people with surprise.

"Kanao, Xuanya, you are here too, and the one behind..."

"Thank you for escorting me at night. I am the guard of Master Yoya, Yomito Jinsai."

A hoarse voice sounded.

The armored man looked at the three little ones who were in awe, and reached out to the yellow-haired man in the middle who was making a fuss.

"Nice to meet you. You must be my wife Zenitsu..."

————————————

Midnight.

On the small road leading to the swordsmith village.

Because the location had been exposed, the group went directly according to the map.

Tanjiro looked at the figure leading the way in front with curiosity.

"I didn't expect you to come with us, Mr. Rengoku."

"Yes, I'll go with you too."

"Yes, yes."

At this time, Nezuko had already crawled out of the backpack and was crawling back and forth on Lin Heng's back.

Looking at this harmonious scene in front of him, Tanjiro smiled sincerely.

"Since not long ago,

, Nezuko seems to have suddenly fallen in love with Mr. Rengoku. She is very happy to be with you. Thank you, Mr. Rengoku."

"Stop talking, Tanjiro, please stop talking." Zenitsu looked heartbroken.

"Hmm? Maybe she feels close to me."

Without looking back, Lin Heng accurately grabbed Nezuko who was moving restlessly behind him and snatched the test tube with light blue liquid from her little hand.

"You can't play with this thing."

Nezuko turned her head away.

"Mr. Rengoku, what is that? Is it dangerous?" Tanjiro looked at the potion curiously.

"It's the human transformation potion developed by my sister."

Kanao, who had been silent all the time, quietly raised her head.

"But the finished product has just been made, and the effect is average. It can only barely make the newly transformed ghost turn back into a human, but if Nezuko uses it, it will damage her body. "

Everyone's eyes lit up, and just as they were about to speak, Lin Heng got ahead of them.

"That's right, this is what will happen if you use it forcibly."

The forward steps suddenly stopped, Lin Heng curled his lips, and injected the liquid in the test tube into his body in the eyes of everyone.

Before he could feel happy about the successful development of the human transformation drug, Tanjiro saw Lin Heng's figure shaking and falling straight to the ground with disillusionment.

The air in the woods was quiet for three seconds, and then a thunderous high-pitched sound rang out.

"Ahhhhhhhhhhhh!!! Ghost!!!"

Zenitsu made a sharp explosion, and in a trance he seemed to see his grandfather waving at him.

So he came back to his senses and held the Sun Blade tightly with both hands.

"Mr. Rengoku is a ghost!!!"

The Jinsai helmet on Xuanya's back was full of echoes, and his brain was stunned by the shock.

"You're so noisy, Zenitsu, calm down, it's not what you think. "

"Oh my, this is unbelievable, this is unbelievable, you actually found me."

A teasing voice came.

Lin Heng quickly decomposed the transformation potion, while holding Nezuko and standing up easily.

"What a pity, it seems that I can't leave you here."

(Only a few people in the Demon Slayer Corps know Lin Heng's identity as a demon, and most people still see him as a god)

At this moment, in his ears was the pleasant sound of the real value increasing, but unfortunately it stopped at 99% and did not move.

Shaking his head, the effect of the first-stage transformation potion was rapidly weakening, and Lin Heng drew out the Sun Wheel Sword and moved forward slowly.

"What should we do? Since we are exposed, we must not let you leave here alive."

The approaching shadow covered everyone, and the terrifying breath made several people tremble.

"What should we do, what should we do, so strong is indeed not human." Zenitsu looked up and looked around at a loss.

"Asshole, we can't beat him. "Zhuzhu gritted his teeth and pulled out his two swords.

Only Tanjiro remained motionless.

Some echoes from the past rang in his ears.

"People who fight monsters must be careful to prevent themselves from becoming monsters..."

Is that so?

Red spots lit up on his forehead, and Tanjiro's eyes suddenly became determined.

Swish——

The flames exploded, and Tanjiro's figure turned into a fire dragon soaring into the sky.

The God of Fire Kagura, the Dragon of the Halo Head danced!

"Please give me Nezuko, Mr. Purgatory!"

Bang——

The sound of metal interweaving rang out, and Lin Heng easily held the fire dragon.

Under the desperate eyes of everyone, the other hand pointed to Tanjiro's forehead.

Da.

Unexpectedly, Tanjiro just shook his head slightly.

"Haven't you grown a lot? You dare to swing your sword at me. ”

Lin Heng slowly turned around after carrying Nezuko, who was moving around on his back, onto Tanjiro.

“Jinsai will explain everything to you. We are not far from the swordsmith village. I will go first.”

His figure flashed and gradually disappeared into the dense forest.

“Goodbye, Tanjiro.”

“I knew it.”

Tanjiro relaxed his whole body after taking a deep breath and fell to the ground with some exhaustion.

The worried crowd quickly surrounded him, and Tanjiro in the center looked at Lin Heng’s departing back.

Thinking back to the story of that year, he couldn’t come back to his senses for a long time…

(The recent episodes of anime are a bit too joyful.)
