Reborn as Platycodon, an infinite journey begins from Demon Slayer

Nightmare had merged himself with the train. Under his control, the train shook violently, and disgusting balls of flesh began to emerge from the entire carriage.

Tanjiro pulled out the Nichirin sword in his hand and attacked the ball of flesh, cutting it off with one knife, but the ball of flesh quickly recovered and continued to attack Tanjiro.

"Tanjiro, we need to kill the nightmare as soon as possible. Once he is fused with the train, it will be even harder to kill!"

A pleasant female voice reached Tanjiro's ears. It was Tanjiro's shikigami who was communicating with him in his mind.

【Lingyu】

【Gender: Female】

[Race: Cannibal]

[Level: A level (level 33)]

[Vampire magic: analysis, large-scale induction, breath elimination, sound transmission, mental resistance, shield creation]

[Introduction: A very rare auxiliary female ghost in the world of "Demon Slayer: Kimetsu no Yaiba". She was very satisfied with Kamado Tanjiro's performance when she saw her at Fujisei Mountain. Kamado Tanjiro also chose her because of her special vampire technique. As his shikigami, although his support is strong, his actual combat ability is extremely weak, so he usually won't go into battle. 】

"Lingyu, are you saying that we are equivalent to being in the body of a ghost now?" Tanjiro was shocked after hearing this.

"Yes, these meat balls attacking you are only part of his body. No matter how you chop, they will not cause harm to him. Hurry to the front of the train, that is his vital point." Ling Yu said.

"Okay, I understand!"

"God of Fire Kagura!"

"Halo Dragon Head Dance!"

The situation was urgent, Tanjiro did not hold back, slashed the Nichirin sword, and instantly produced a high-speed combo like a fire dragon. The fire light cut off the incoming inner group, and because of the characteristics of its breathing method, the flesh was The group was temporarily unable to regenerate, so Tanjiro took this opportunity to quickly rush towards the front of the train.

"What's going on? Why can't it regenerate?!"

"...Could this be the Breath of the Sun? You are the user of the Breath of the Sun!!"

Nightmare can also see at this moment that even the He Dao can only slow down the regeneration speed, but it can make the ghost unable to regenerate, even if it is only temporary, it is extremely terrifying.

In addition to the legendary Breath of the Sun, Nightmare really can't think of any other breathing method that can have such an effect. After all, that adult also suffered a big loss from this Breath of the Sun.

......

In order to protect the lives of everyone on the train, Purgatory Anjuro would turn into a fire dragon every time and cut off the meatballs in several carriages in an instant.

On the train, Anjuro Inferno was busy protecting hundreds of passengers, while Tanjiro on the other side was currently confronting Nightmare on the top of the train car.

Nightmare saw Kamado Tanjiro rushing onto the roof of the car, and he laughed excitedly, "Today is really my lucky day, a pillar, and the person who the Lord specially ordered to kill, use the sun to Use your breath to kill those who are at the bottom of the spider mountain in that field."

"That sir? Is it Muzan Kibutsuji?"

Nightmare ignored it and instead smiled mysteriously. Tanjiro frowned and disappeared from the spot. He flashed in front of Nightmare and slashed his neck with the Nichirin Sword. Nightmare's head fell to the ground.

After his head was chopped off, the connected piece of flesh grew a new head. Nightmare did not die. Instead, he continued to talk to Tanjiro like a normal person.

"It's useless, I'm immortal on this train!"

The train sprouted several more meatballs and launched an offensive against Tanjiro. Tanjiro cut the meatballs while hiding, but the meatballs quickly returned to their original shape.

"It seems that even if you know the Breath of the Sun, you can't use it continuously." Nightmare's offensive became more fierce.

"Tanjiro, we found it. Nightmare's neck is in the carriage under these meatballs!"

It turns out that Tanjiro did not use Breath of the Sun continuously because he followed Ling Yu's suggestion. Firstly, it could paralyze the opponent and achieve miraculous effects at critical moments. Secondly, it also gave Ling Yu time to find the location of the nightmare.

"Now that we've found it, let's make a quick decision!"

"Kagura, the God of Fire, Round Dance!"

The Nichirin sword was wrapped with extremely hot flames and slashed forward in an arc, instantly cutting off the incoming meat ball. The meat ball could not regenerate for the time being. Tanjiro raised his right hand.

"Iron piece broken!"

The powerful force directly blasted a big hole out of the top of the steel carriage.

"What a strong and disgusting ghost spirit!"

"Tanjiro, right below is the spine of the nightmare!"

"understand!"

Nightmare suddenly lost the previous relaxation and playfulness, showing a look of panic, and a mouth grew on the back of his hand.

"Vampire Art: Forced drowsiness and hypnotic whispers!"

The mouth on the back of Nightmare's hand uttered the word "Sleep", and when Tanjiro heard it, he was immediately forced to sleep.

Before Nightmare could breathe a sigh of relief, Tanjiro suddenly woke up.

"How can it be!?"

Nightmare was shocked. He used the vampire technique again, but Tanjiro soon woke up again. This time Nightmare entered Tanjiro's dream and saw an amazing scene. Tanjiro was dragged out of the dream by a female hand. .

"Are you traitors again!?"

Except for Tanjiro's shikigami, there was no one else here, and Nightmare was so angry that she gritted her teeth.

"Tanjiro, if you hold on for a while longer, I can fully analyze his vampire technique!"

"Okay, I'm sorry to trouble you, Lingyu!"

Infinity train in the sky.

A miko was using her moon steps to follow the Mugen Train. From above, she could see the battle between Purgatory Anjuro and Kamado Tanjiro.

"Yes, my strength has improved a lot."

Kikyo sensed the spirit feathers on Tanjiro's body and couldn't help but blink, sighing that Tanjiro was indeed the destined son of the Oni Blade world and could actually be favored by spirit feathers.

You must know that Ling Yu's auxiliary ability has been coveted by many members of the Demon Slayer Team. Even Mizuru Fusukawa, who hates ghosts extremely, has invited him. This shows that Ling Yu is special.

But for so many years, Lingyu only got close to her, and he didn't expect that he would eventually become Tanjiro's shikigami.

As soon as Kikyo arrived at Mugen Train, she received a task issued by the system.

[Release of side missions: 1. Protect the Infinity Train passengers without any death! 】

[2. Kill the last one, the ghost of sleep! 】

[3. Change the fate of Purgatory Xingjulang being killed by Yiwozuo! 】

[Task reward: Breathing of Fire, Coordinate Transfer Talisman*1, Soul Contract Talisman*3! 】

"Oh, the system is so considerate. These two kinds of talismans came in time."

However, Kikyo didn't go down to help immediately, and the system didn't say that she had to kill it herself. In other words, Tanjiro could kill Nightmare, which would be enough for the two of them to practice. Anyway, with her here, they wouldn't be afraid of accidents.

On the top of the Mugen Train carriage, Tanjiro ran quickly, jumped directly into the front carriage of the train.
