Control the Butterfly Effect from Demon Slayer: Blade

Horie looked at the big gourd that Zenitsu had blown open, with a troubled expression on his face:
"My request to you is to blow up this gourd, not just blow it open, Shanyi, you... Forget it, just barely pass."

After thinking about it, Horie finally let Zenitsu go.

More or less it was because the kid was too nervous to perform well, but it did not mean that his own ability and breathing power were not enough, so let him go for now.

Zenitsu breathed a sigh of relief after hearing Horigake's sentence.

He gasped for breath quickly, to relieve the feeling of lack of oxygen, rolled his eyes upwards, wobbled so much that he almost fell down.

Tanjiro and Inosuke from behind rushed up to support him.

But even if he was supported by his two companions, Shan Yi was still unhappy:
"You two are too disrespectful. You only came to help me now, and now to make amends. It's too late! My young heart has been seriously hurt..."

Regardless of Zenitsu's resentful chatter there, Horigake faced the four cubs and officially announced:
"Congratulations to the four of you, you all passed my exam, and your strength has made great progress."

The four little ones rejoiced.

Just when Horiyake announced that they passed the exam, the system in Horiyake's mind had a movement:

"Ding! The host, Tanjiro, Zenitsu, Yae, and Inosuke, these four are stepson, which had a certain degree of major influence on the protagonist group in the original work, disturbed the fate to a certain extent, and triggered a negative butterfly effect: Infinite Train battle!"

Hearing the voice of the system again, Horigake couldn't describe his mood at this time.

It stands to reason that the system can unlock itself, which is obviously a good thing.

But every task released by the system, and the negative butterfly effect released by the system, are all things that can't be solved, which makes Horyue very speechless.

Just like this time.

It is indeed something that is completely absent in the original book that I adopted the four little ones as my stepson. As a result, such a thing caused a strange negative effect.

This negative butterfly effect is called the Infinity Train War.

Isn't the battle of the infinite train the same as the battle in the original plot?

In this battle, I encountered the nightmare of the first one of the last string, and also met Yi Wozuo of the third one of the upper string, which directly resulted in the death of the elder brother Purgatory Xing Shoulang. How many people are upset.

I don't know what the hell will happen in this battle now?

Forget it, since the system has been disabled for him, why do he still have so much resentment?It's clear that you get cheap and sell well.

So Horiyake stopped thinking so much, and directly asked the system in his mind through his thoughts:
"Okay, okay, just talk about it, what is the inexplicable mission that can't be achieved this time?"

Immediately afterwards, the system issued a sound:
"Ding! The system issued a task:
Ask the host to solve the negative butterfly effect: the infinite train battle!

The wireless train battle in the original book will still happen.

Everything is the same as the original, and should have developed according to the original plot.

However, because the host defeated Yiwozuo before, Yiwozuo was greatly stimulated in the follow-up. He began to train hard, and until today, his strength has been further strengthened.

Now Yi Wozuo's strength is much higher than that of the original Yi Wozuo.

If the host sits idly by and allows things to continue to develop according to the original plot, not only will Purgatory Xingjulang die in the next Infinity Train battle, but the four little ones may also be wiped out.

Once the protagonists are all dead, the subsequent situation may all collapse.

To avoid such a bad situation, the host is invited to participate in this infinite train battle, defeat the enhanced version of Yiwozuo, and protect the four little protagonists.

Reminder: It's just that Yiwozuo's strength has been strengthened, and the plot of the original book has basically remained the same. What more reminder do you need?
However, there can be another kind reminder.

Another kind of warm reminder, reminder: Please master this mission well, complete this mission as much as possible, and don't make mistakes.

Because the task reward this time is a very useful reward.

Once the host gets the reward of this mission, he will be able to retreat in the face of no misery in the future with absolute certainty, and he will also have enough means to restrain Naruto's spatial ability.

Task success reward: Tianlei Breath·Lu Zhixing.

Punishment for mission failure: All four cubs of the protagonist group died, and the subsequent fate fluctuated greatly, and the direction of this world ran in an unpredictable direction. "

The system said a lot more.

Listening to the things the system said, Horigake found something that caught his attention.

The first is the task situation this time.

There is nothing to say about this mission, except that Yiwozuo's strength is stronger than the original book, no other accidents will happen, just follow the steps.

Then there is the mission requirement of the system this time.

System requirements, I only need to protect the four little ones of the protagonist group.

In other words, from the system's point of view, as long as the undeserving protagonists in the original book are not dead, that's fine.

In other words, the death of Purgatory Kyojuro has nothing to do with the system.

Whether Yiwozuo is dead or not has nothing to do with the system.

Thinking about it this way, Hori Yue deeply felt that his system is really a cold guy!

How many people were upset by the death of the eldest brother back then?
This time, he finally had a chance to save, and had a chance to set things right, how could he not save Xing Shoulang from Purgatory?

Not only should Xing Shoulang be saved from Purgatory, but Yiwozuo must be completely left behind.

Although Horiyue admires the third brother and regards Yiwoza as a good opponent, an enemy is an enemy, and only a dead enemy is a good enemy!

It can be foreseen that even if the third brother this time is an enhanced version of the third brother, he is definitely not his opponent.

Horiyue intends to completely keep Yiwoza this time, and he will never give up!
I'm afraid that at the last moment, Wu Mi will not turn a blind eye, and Wu Mi will ask Ming Nu to rescue Yiwozuo.

But Horie will not let this happen.

It was annoying enough to let Yi Wozuo escape last time. This time, as long as I am fast enough, I can completely kill Yiwozuo before there is no tragic reaction!

Again.

The third brother is indeed a good guy.

But dead enemies are the best enemies.

In addition to the system's requirements for the mission, what interested Horigake the most was the mission reward this time.

The system also specifically stated in the warm reminder that the mission rewards this time are very important.

If he gets the mission reward this time, he will be able to retreat in front of Wu Mi in the future, and he will also have a way to restrain Naruto.

I have to say that Horie was very moved.

Needless to say, retreating in front of Wu Mi, this method is undoubtedly a life-saving method.

And to restrain Naruto...
