Demon Slayer: Become the villain Boss Muzan

The two of them were very excited.

When Xiaomei and Jifutaro were sent to the Infinite City by Yunyi, they were confused when they saw the "disheveled" Mingnu handed over two pieces of paper with densely written questions and two pens.

The two of them remembered that the "assessment" that Muzan mentioned was a cultural assessment.

Really, an exam?

Zheng——

Mingnu looked at the confused two people, stroked the pipa strings, and the two were sent to the exam table.

The confused two saw Lord Muzan eating snacks on the high ground.

Oh, Mingnu is the deputy examiner, and Lord Muzan is the chief examiner.

Muzan reminded him, "The papers will be collected in one hour."

The two realized that there was still a time limit, and hurriedly grabbed the paper and began to answer the questions.

Time passed quickly. While Muzan was waiting in boredom, the two "examinees" finally handed the papers to Mingnu when Mingnu reminded them, "Time is up."

With Muzan here, no one would dare to cheat even if he only used one set of papers from beginning to end.

Mingnu started to mark the papers ruthlessly.

In just a few minutes, the results came out.

Under the nervous gaze of Xiaomei and Jifu Taro, Mingnu looked at Lord Muzan:

"Lord, they passed."

---

Muzan regretted it very much. He suddenly felt that technology did not need to develop so fast.

Look, coal mining has begun.

Fortunately, it is still regional pollution, and Muzan can avoid where the pollution is serious.

Fortunately, there are no smoky factories around his house.

After thinking about it, he felt that he had to remind Asanuma Shizuji and the others, dare to make the air so smoky?

Now this place is not just a country, for Muzan, it is almost his territory.

Compared with Maruoka Masahiro and Maruoka Kinko, who mainly deal with political affairs and control the overall situation, Asanuma Shizuji's current experience is mainly focused on the new policies introduced.

Developing technology, commerce, shipping and the like.

So, Muzan found him.

"Lord Muzan..."

Aren't you making things difficult for us?

Asanuma Shizuji looked embarrassed. To get to this point, some sacrifices are necessary!

Looking at Muzan, Asanuma Shizuji looked embarrassed.

Muzan scratched his head: "Okay, don't take too big steps, take it slowly, and also, you can plant more trees and the like, that thing is good for the environment, don't be stubborn, have you lived for hundreds of years in vain?"

So, not long after.

New policies were introduced.

The area around the factory must be planted with trees, and transplanting of mature trees is not allowed...

To be honest, it's really convenient to solve the problem with just one sentence.

Soon, Muzan learned the news from Douma-the Demon Slayer Corps moved.

After all, they were discovered by the demons, even if they didn't know that "Xu Xing" was the demon king, they had to leave their original place.

Time passed quickly, and Douma finally waited for Akagi Rie to retire.

The reason was also very simple, the fracture was broken in the battle and could not be healed.

When Douma arrived, she had already chopped off the half-demon's head with one knife.

The bodies of four or five half-demons lying beside him were gradually dissipating.

Next, Douma kept explaining according to what the trash boss said.

The effect was also very gratifying, and Akagi Rie finally accepted Douma.

So, Douma moved directly to the vicinity of where Akagi Rie lived after retirement, and greeted him with a smile every day. Akagi Rie became more and more accustomed to having a grinder next to her.

After finding out that Douma likes to eat wisteria cakes, he always buys wisteria cakes for Douma.

Later, Douma watched Akagi Rie find her own happiness, and like a younger brother, he watched her get married and have children.

Douma also knew that he had never had any thoughts of a lover with Akagi Rie, but just made up for the maternal love and family affection that he had once lacked.

Today, he finally understood the good intentions of Master Muzan.

Muzan: "???"

---

Another dozen years passed quickly, and Muzan looked at the "steam car" in front of him.

He looked at Shan Zhuoan again.

Awesome!

You are almost a hundred years ahead of the steam car in the West!

Overtake on the spot, right?

Shan Zhuoan scratched his head with a simple face, and the other "team" members around him gathered around him.

Although he did not complete it alone, he is also one of the main contributors.

"Good, you did a good job, keep it up, if you need anything just ask."

Muzan looked like he was entrusted with an important task, and patted his shoulder with satisfaction.

Then he walked around and looked at this

A steam car that looks more like a carriage.

The "car" at this time is completely different from the cars of later generations, but the steam engine has been used as a power source.

Muzan gave each ghost head a satisfied look and left here, suddenly looking forward to it.

In fact, the steam car is just an attempt. Their real goal is electricity!

They have the knowledge given by Master Muzan, how can their goal be limited to a mere steam engine?

They want to build a generator!

Electric motor!

They want to start an industrial revolution!

Jump directly to the third industrial revolution!

ψ(｀∇´)ψ

Later, Muzan watched huge ships float on the ocean, cars began to appear, and factories rose from the ground.

Workers appeared.

Fifty years passed quickly.

Muzan looked at the so-called "phone" in his hand and was shocked!

This hang-up...

Thanks to the infinite life of the ghosts and the knowledge of Muzan's people, plus unconditional support, for fifty years.

He invented everything he could think of, including generators, gas engines, ships, light bulbs, and telegraphs.

Even Muzan saw people squatting in the bushes with guns in their hands hunting.

At the same time, the chemical industry also started its journey.

After all, the microscope had already been invented by him!

Tamayo and Yanagisawa Kiyuki had already started observing the microscopic world with microscopes.

What's more interesting is that the country's name was decided. As a "die-hard fan" of Muzan, the country's name was "Tsujikoku" and the flag was a big Tsuji character.

Muzan: "..."

(ー△ー；)

Well, this is really his territory now.

One day, a ship came back with a handful of seeds.

Three years later, Muzan ate what he had always dreamed of - melon seeds!

The Demon Slayer Corps was stunned.

How come the world changes so quickly?

(((;꒪ꈊ꒪;)))

In fact, it's not just the Demon Slayer Corps, there are also demons.

As an "old man" who has lived from the Warring States Period or later, he is used to the life of decades ago. Seeing the world changing almost every day, he is confused.

When he thought of others who are also demons, such as Sugihara, changing the world, while he is playing badly, he suddenly had the urge to roll up.

But when he thought of Muzan-sama, who is playing badly, he suddenly became Buddha again.

(:3_ヽ)_

And Douma, watching Akagi Rie, who is both his sister and mother, getting older day by day, accompanying her with a still young appearance, watching her children getting old.

On this day, Douma stood outside and watched Akagi Rie and her children send her husband off.

Soon, Akagi Rie finally came to the end of her life.

Standing by her bed, Douma had no smile on his face this time, just looking at her.

Akagi Rie tried to reach out and grab Douma's arm, and Douma stretched out his hand for her to hold.

The rough old hand tightly grasped his delicate hand like a child:

"Douma, promise me that you must stick to yourself, I believe in you."

Douma nodded obediently.

The withered yellow leaves outside the window fell gently, and Akagi Rie smiled gently, and her pupils gradually lost their light.

The sunlight near noon shone through the wooden window onto half of Douma's face.

The shadow of a fallen leaf passed across his cheek.
