Controlling the Butterfly Effect from Demon Slayer

After listening to the system's explanation, Hori Gaku felt a little confused:

"This... My personality is not as bad as in the original novel, and it did not affect Xingming's imprisonment. This is a good thing, so it is a positive butterfly effect. I understand this.

But I learned the first form of Thunder Breathing, which is also a good thing! How can it cause a negative butterfly effect! ?"

The calm electronic sound of the system sounded in his mind:

"The butterfly effect involves cause and effect, time and space, which is unpredictable and unpredictable. The probability of positive and negative butterfly effects occurring is 50%."

"Okay, what exactly is this negative butterfly effect that I accidentally caused this time?"

"Ding! The host has learned the first form of Thunder Breathing, breaking the fate, and the negative butterfly effect caused is: the protagonists of this world, Tanjiro Kamado and Nezuko Kamado, are about to die!!!"

"What the hell!?!"

Hori Gaku jumped up excitedly, his heart was in turmoil:

"My future brother-in-law and future wife are going to die!? Just because I learned the One-no-kata!? I wouldn't have learned this if I had known!? What should I do?"

Hori Gaku cried out in the snow, and quickly calmed down and thought quickly, but after thinking for a long time, he had no idea:

"It's all my fault for not watching the show carefully. I have no idea where the Kamado family lives, and I can't find them! How can I save them! ? My wife! My brother-in-law!

What should I do! ? What should I do! ?

Kyogoku Mountain! The Kamado siblings' current destination should be Kyogoku Mountain! We should be able to find them by following the direction of Kyogoku Mountain! Ask the stinky old guy, he will definitely know where Kyogoku Mountain is!

And there's also Tomioka Giyu! Tomioka Giyu should have seen the Kamado siblings at this point, so please ask Tomioka Giyu to look for the Kamado siblings and you should be able to find them!

Damn it! The question is... is there enough time! ? System, system, what exactly do you mean by imminent death? How long will it be! ? That

's right! System! Aren't you a butterfly effect control system? You must have a way!"

I don't know if it was Horitake's illusion, but the electronic voice of the system in my mind seemed a little helpless:

"Ding! Please don't get too excited. One of the responsibilities of the system is to help the host resolve the negative butterfly effect."

"Then hurry up!"

"Ding! The system issues a task:

Please solve the negative butterfly effect, the death of the Kamado brothers and sisters!

The system has a guidance function that can help the host find the Kamado brothers and sisters.

According to the system detection, the host's current strength is enough to fight against the dangers that the Kamado brothers and sisters are about to encounter as long as they are cautious enough.

Warm reminder: There are still 24 hours before the death of the Kamado brothers and sisters, please hurry up in time.

Reward for successful mission: Advanced moves of Thunder Breathing·One Type·Thunderbolt Flash.

Penalty for failed mission: Kamado Tanjiro and Kamado Nezuko die, the host loses his future wife and future brother-in-law, and his fate changes greatly, and the butterfly effect collapses further!"

Looking at the details of this task, Hori Gaku was a little stunned.

So... that's what happened.

I triggered the butterfly effect. The system doesn't care about the positive butterfly effect. The system will solve the negative butterfly effect by issuing tasks by me personally, and the system's rewards can enhance my strength.

Kill two birds with one stone!

Hori Gaku was in a state of surprise and stagnation. At this time, a 24-hour countdown appeared in the upper right corner of his sight. There is no doubt that this is the system's time prompt!

"System, well done! I'll leave right away!"

Without saying anything, Hori Gaku ran home and went straight to Jigoro's house in Momoyama!

He pushed the door open very roughly, almost knocking it over. Hori Gaku rushed into the house and started packing his things. Jigoro in the house looked confused:

"What are you doing, little brat?"

Horitake quickly cleaned up without even looking up:

"Stinky old man, this coat is quite warm, I'll take it first! I'll also take your spare Nichirin sword! And these rice balls, they'll be your dry food on the road……"

The well character above Ci Wulang's head burst out:

"Brat, what on earth are you going to do! ?"

After finishing packing, Horitake ran out and quickly went down the mountain.

Jigoro stood at the door of the house and shouted angrily:

"What's going on? Where are you going? When will you be back?"

From the branches in the distance, Horitake's distant voice came back:

"I'm going to meet my future wife and future brother-in-law! Don't worry, I'll be back in a few days.……"

Holding onto the door frame, the old man turned into a beady-eyed man:

"Future wife and future brother-in-law? How come I don't know anything about this? Could this be the reason why he came down the mountain several times before?"

Thinking about it, Ci Wulang began to fall into beautiful fantasies, petals appeared around him, and the painting style began to become cute:

"That's great. It's time for this brat to consider his lifelong affairs. I wonder which family this girl is from. Is she pretty? Is she virtuous? Is she worthy of my brat?"

On the other side, Horitake, who ran down the mountain, found the road and hurried along according to the system's directions.

As he ran, he thought to himself:

I will definitely catch up, I will definitely catch up! The system will not issue tasks that I can't do!

As long as I maintain a good breathing rate and use the Thunder Breathing well, I can make my physical strength more lasting and my speed faster. Maybe I can also learn to breathe with full concentration.

Nezuko, my future wife, you can't be in trouble!

Tanjiro, although it's a bit incidental, but you can't be in trouble either. If you are in trouble, the plot will be messed up, and my foresight as a time traveler will be discounted!

In this way, Horitake was on the road for 24 hours without stopping. Stop.

If you are hungry, just eat a rice ball; if you are thirsty, just drink some stream water; if you are tired, take a rest; if you are sleepy... people on the road will not feel sleepy!

In this way, a day and a night passed, and the 24-hour countdown was coming to an end.

So, what is the fatal danger that the Kamado brothers and sisters are about to face?

It stands to reason that when the Kamado brothers and sisters first encountered a disaster and went to Gorge Mist Mountain, except for the last encounter with a Buddhist temple ghost, they did not encounter other ghosts on the way.

Due to the occurrence of the negative butterfly effect, this time, the Kamado brothers and sisters were on the road, unfortunately, they encountered another ghost, and it was a ghost with special powers!

""Nezuko!" Tanjiro shouted at his sister at the top of his lungs.

The brother who wanted to protect his sister is now facing the opposite situation, with his sister protecting him!

On the way, they unfortunately encountered a ghost. Tanjiro was no match for this ghost, but fortunately Nezuko, who had turned into a ghost, was quite powerful. She bravely rushed out to protect her brother.

Covering his bleeding arm, watching the ghost fighting back and forth with Nezuko, Tanjiro held an axe, flustered and helpless.

In fact, in terms of strength and speed alone, this ghost is just so-so.

However, this ghost has a special ability that injured Tanjiro and made him suffer!

Staring at the ghost, Tanjiro realized that the enemy was about to open his mouth, and hurriedly reminded his sister loudly:

""Be careful!"

The ghost opened his mouth and spit out four fangs from his mouth! It was like four darts shooting at Nezuko!

Although Nezuko was reminded to dodge, a fang still hit her back!
