Control the Butterfly Effect from Demon Slayer: Blade

Listening to the system's explanation, Horigake fell silent and understood.

Resurrection from the dead is always a provocation to the laws of the world, and it is the most blatant provocation!
As long as this world has its own rules of operation, this kind of thing will never be allowed to happen!

The world can allow Tianlei to breathe, can allow Wuxiang's knife, and can even allow vitality to replenish potions, but it cannot allow the resurrection of the dead.

However, his own system is superior.

The system feels that no matter whether the world is allowed to be resurrected from the dead or not, it must be killed first and played later!
Therefore, the system urgently needs Horigake to use this stand-in doll.

Judging from the current situation, Horigake himself does not need to use a stand-in doll.

That being the case, it is better to let others use it.

That's the idea of ​​the system, and why.

Horigake was speechless. After a while, he shook his head and sighed:
"The situation and reasons are so complicated...

Forget it, that's it.

Anyway, with my current strength, there is basically no need for a substitute doll, so it is better to give this substitute doll to Tanjiro and Nezuko to save their siblings.

By the way, the system, if I give them this stand-in doll, does it count as helping them?In other words, after the brothers and sisters use the dolls to resurrect, will my mission be considered a success? "

The system was silent for a while, then replied:

"The requirement of the task is that in the following plot of Forging Sword Village, the host is not allowed to help or save the protagonist's brothers and sisters.

But before the plot of Forging Knife Village, it doesn't matter. "

Horie nodded, understanding.

In fact, this is a word game.

Looking at the stand-in doll in his hands that has been kept close to him for many years, Horigake shook his head.

This time the double doll can't be kept, so it's inevitable that it will be sent out this time, and the lives of Tanjiro and Nezuko will be given priority.

Although it can only guarantee one life, it is almost enough.

Based on the strength of Tanjiro and Nezuko, it is basically impossible for two brothers and sisters to suffer together, at most, one of them will be life-threatening.

After shaking the substitute doll in his hand, Horiyake continued to ask the system in his mind through his thoughts:

"Okay, I already know the details of the mission, so what about the punishment for mission failure? And the reward for mission success?
Especially this task reward, I have been coveting it for a long time.

Before the system, you promised me to help me solve the problems of Tianlei's breathing and Wuxiang's knife, this time you can't pretend to be deaf and dumb. "

The system answered honestly:
"There is nothing much to say about the punishment for the failure of the final mission this time, it is nothing more than the protagonist Tanjiro and Nezuko brothers and sisters, one of them died, or even both died.

Even if the protagonist is dead, the subsequent development of the plot may collapse, and the fate and laws of this world will undergo great changes, and even chaos.

If the host is in this world, it will also be greatly affected.

And the reward for the success of the final mission is just as the host wishes.

The mission reward for this final mission is... Tianlei breathing method, upgraded to Tianlei breathing method! "

After hearing the mission reward, Horie Yue opened his eyes and sat up straight!

The amount of information is a bit large.

The mission reward this time is to upgrade the Heavenly Thunder Breathing Method to the Heavenly Thunder Breathing Method!
Is there any connection between Tianlei breathing method and Tianlei breathing method?

There does seem to be a connection.

One is breathing and the other is exhalation. It sounds similar, but in fact they seem to be quite different.

Breathing is breathing, there is nothing to say about it.

But Tuna, obviously taller, and even has a sense of sight of practicing exercises!
It's worthy of an upgrade, a big upgrade in one upgrade!

When the Tianlei breathing method is really upgraded to the Tianlei Tuna method... my Wuxiang knife will definitely be able to output at full power, right?
Thinking of this, Horie took a deep breath to regain his composure.

With such an important mission reward, this final mission is bound to succeed!

Tanjiro, Nezuko, you two brothers and sisters must fight this time, you must fight!

Now the plot of Forging Sword Village has not fully started, why don't I start a small stove for Tanjiro.

Thinking of this, Horigake looked towards the Butterfly House next door, and shouted loudly over there:

"Tanjiro! Come here! I have something important to tell you!"

Horigake's voice was like an electromagnetic wave, and it was transmitted steadily to the training ground on the side of Butterfly House, and all the little ones who were training in the training ground heard it.

Yes, today's situation is quite special. The little ones did not train at Horigake's house, but chose to train with Kanao at the training ground of Choya.

When the children heard Horigake's voice, they all looked at Tanjiro who was training.

Tanjiro wiped the sweat off his brow, smiled brightly and said:
"Senior has something to ask me, I'll go over here, everyone don't have to wait for me, just continue to the next stage of cultivation, I will catch up when I come back."

Everyone nodded and didn't do what he thought.

Tanjiro hurriedly trotted all the way, ran out of the training ground, passed through the circular arch, and came to the courtyard on Horigake's side.

After Tanjiro came over, he saw Horigake sitting on the porch, walked over quickly, and stood in front of Horigake:

"Senior, do you need me?"

Horigake nodded, and kept silent for the time being. Instead of directly explaining the situation, he first asked Tanjirou how he was doing now:

"Tanjiro, how's your training going?"

When asked this question, Tanjiro replied in a high-spirited manner:
"I practice very hard every day, and I feel that I am improving every day."

Horie nodded silently.

In fact, it is not necessary for Tanjiro to say in detail, Horigake can see the specific state of Tanjirou at a glance.

Tanjiro's current strength is very good. It can be said that he is the swordsman who is second only to ten pillars in the Demon Slayer team.

If this kid activates the Breath of the Sun with overload, his strength will be close to Butterfly Ninja, and even surpass Butterfly Ninja temporarily, which can be said to be very good.

This strength is enough, and it is enough.

It is not enough to say that it is not enough.

With Tanjiro's current strength, it is not a big problem to survive the next calamity.

But with Tanjiro's current strength, it is not enough to participate in the final battle in the near future, at least the basic strength must reach the pillar level.

Thinking of this, Horigake shook his head lightly again.

That's all, you can't force too much, Tanjiro has grown to this level, it is already very good, it is not advisable to overthrow the seedlings.

At this time, Horigake looked at Tanjirou seriously, and began to tell him some of the situations that will be encountered next:
"Tanjiro, you should know that I have the ability to see the future for a short time, right?"

Tanjiro nodded, then his expression changed.
