The afterlife blew up Gensokyo

The desires in people's hearts are like a boulder rolling down a mountain; once started, they can never be stopped. If it weren't for the existence of some people who still uphold their principles and stop them, it's hard to imagine how things would have developed.

Saigyouji Yuyuko is the eldest daughter of the Saigyouji family and the only daughter of Saigyou Hoshi. In terms of personality, she inherited Saigyou Hoshi's ethereal and elegant nature. It is rare to see her angry, and she always has a gentle smile on her face.

This is a girl who is hard to dislike. It is precisely because of her that even though the other people in the Human Village have some complaints about the increasingly arrogant behavior of the Saigyouji family's followers, they have never said a bad word about Saigyou Yuyuko.

—Only within the Saigyouji family were she secretly referred to as a cursed being.

Any living being that comes into contact with her for a period of time will suddenly and mysteriously die. Whether it's a plant, a pet, a human, or a monster, none can resist this inexplicable curse.

Saigyouji Yuyuko had no idea where this curse came from. When she asked her father, he only gave her a puzzled look and a heavy sigh. She longed for excitement and friends, but she was forced to taste loneliness alone.

That afternoon, as she sat quietly under the eaves admiring the cherry blossoms, a strange presence suddenly appeared before her—a severely injured, almost dying, blond-haired monster.

Saigyouji Yuyuko used the best medicine to heal the other person, and then carefully hid him in her room. During this process, she didn't even dare to touch him, for fear that the curse on her body would harm him.

This was the beginning of their encounter... under the deliberate design of a certain sage.

Yukari Yakumo is not stupid; on the contrary, she is quite shrewd. If she still wants to be a sage among youkai, then she will have to step forward at that time, which is unavoidable.

But before that, she had already planned her escape route. It might be difficult for humans to understand the past and history of monsters, but it is very easy for monsters to investigate the past of humans.

In fact, from the very beginning, Yukari Yakumo had already set her sights on Saigyo's only daughter. To be honest, she didn't care about the process, only the result. Using the other person's kindness to achieve her own goals was nothing special.

Because of the curse that Saigyouji Yuyuko carries, virtually no one dares to come to this area, making it extremely quiet and arguably the safest place.

Because no one could possibly have guessed that she would choose to hide in the most dangerous place.

How long can a human life last? After Saigyou-shi grows old and dies, the Saigyouji family will be her first target. The day Saigyou-shi dies will be the day the Saigyouji family is destroyed.

At that time, none of the people from the Saigyouji family will be able to escape.

—This is a script she wrote a long time ago.

As the only daughter of the Saigyou Master, she seems to have inherited his strange abilities, though not as powerful as he appears, and seemingly unable to control them. When necessary to prevent the emergence of a second Saigyou Master among humans, she will not hesitate to eliminate him completely to prevent future troubles.

A monster? Don't think of her as too kind. The reputation of the Monster Sage is not based on benevolence, but on the "fearsome name" earned through countless trials of blood and death.

Cold, indifferent, ruthless, powerful... these are the most direct impressions others have of this sage demon. As for things like killing, they are actually not worth mentioning at all to her.

She habitually uses others as pawns to achieve her goals, using acting skills to cover up her truest thoughts. This is true of Matara Oki, and it is also true of Ibuki Suika. If possible, she also wanted to bring that guy under her control, but she failed.

However, she firmly believed that everyone has weaknesses, even that terrifyingly powerful guy. So, over the years, she had been secretly searching for information about the whereabouts of Kazami Yuuka, whom the other party had mentioned... This was also part of her plan.

However, she didn't know when it started, it seemed that after she finally became a sage of the yokai, the friends she had made slowly began to drift away from her. This was true for Matara Okina, Ibuki Suika, and Hoshiguma Yuugi... She would occasionally feel regret in her heart, but it was just regret.

—Until the sudden emergence of the Journey to the West monk.

When she fought that Western-bound monk, a feeling of vastness and imposing grandeur filled her consciousness. In that instant, it was as if he were looking down upon nebulae, and with just a wave of his hand, the heavens would collapse!

This was the second time she had felt utterly powerless. The first time was when she faced the guy who claimed to be forever 18. Although she managed to escape as expected, the injuries she sustained were much more severe than she had anticipated.

But it doesn't matter, everything is still in her plan, and the one thing she has in abundance is time.

Yukari Yakumo had a good plan, but unfortunately she overlooked a very important point... that is, pink hair is always black inside.

Saigyouji Yuyuko had never taken care of anyone before, so she was quite flustered at first. As a result, under her "meticulous care," Yakumo Yukari's injuries not only did not show any signs of improvement, but actually became more serious...

Meanwhile, as Yakumo Yukari was hiding with Saigyouji Yuyuko and facing the biggest crisis of her life, on the other side, Shibai was conducting tutoring for a loli on the Youkai Mountain.

Having witnessed the power of technology wielded by the gods in the Lunar Capital, Hirain Hana realized the most pressing issue facing the Youkai Mountain.

Reform is imperative.

If it weren't for the sudden and unexplained disappearance of Tsukiyomi, the supreme leader of the Lunar Capital, Hirain Hana would have had no doubt that the demons would have suffered a crushing defeat, even with the addition of the demons from the old underground hell.

Even though the same amount of time has passed, why is it that the other side can develop so rapidly, while we are just standing still with almost no change?

Ever since the surprise attack on the Demon Mountain, Hirain Hanako has been pondering this question, but no matter how much he thinks, he can't find a satisfactory answer. Even though he wants to study the power of science to learn from the barbarians and use their superior skills to defeat them, he has been studying for so long but still hasn't made any progress.

It wasn't until Shi Bai arrived that this anxious situation of never being able to get in was finally alleviated.

As the saying goes, with a system in hand, you have the world at your fingertips. Although most of the systems scattered throughout the myriad worlds were transformed from the [Fire Seed World], the system in his hand was essentially a legacy heart created by the entire Eastern God Clan with all their might, and naturally could not be compared with those systems.

In fact, Shi Bai also suspected that the system formed from the inheritance heart of the Eastern God Clan within him was created by the Eastern God Clan after capturing a powerful [Fire Seed World]. However, suspicion was just suspicion, and there was ultimately no substantial evidence.

Without any ulterior motive, and with his own "true luck," he could basically get whatever he wanted. After decisively stuffing a nuclear warhead in as a sacrifice for the summoning, Shi Bai successfully summoned a set of science textbooks from elementary to junior high school.

After summoning it, Shi Bai took a moment to look through it and then subtly discovered that it seemed to be the textbook he used when he was in school, with even his own handwriting on it. Back then, he was a true academic star, so he had carefully collected these used textbooks and kept them at home for his collection.

—But because of this unexpected discovery, he suddenly thought of a very terrible possibility.

This summoning follows the principle of equivalent exchange. Specifically, it involves transferring items from location A to location B, and then transferring items from location B to location A.

Regardless of whether the world he was in during this equivalent exchange was the one he had lived in before or a parallel world, it was certain that the world was related to him. After all, he could still recognize his own handwriting, and he even found some comics he had scribbled on in his textbook when he was bored in class.

So here's the problem: it's not a big deal that your collection of textbooks is gone in that other world, but what's wrong is that a nuclear warhead suddenly appears in your house...

Although this nuclear warhead is very stable and won't explode from a small collision, if such a thing were discovered... it would probably become an unsolved mystery in some world?

Shi Bai felt that this question was worth pondering, so he deliberately spent a minute thinking about it.

As the saying goes, a tall building starts from the ground up. Everything requires a solid foundation. Unlike the Moon Capital, the Youkai Mountain cannot directly plunder technological talents from other worlds and assimilate them. Therefore, it is only natural that they can only start learning from scratch.

To be honest, watching Asakura Rikako and those kappa tengu clutching their elementary to junior high school textbooks and studying them like they were precious treasures always made Shi Bai feel inexplicably strange and uneasy.

New knowledge, new disciplines, new civilization, new heritage.

Faced with this entirely new knowledge, completely different from their basic understanding, the scientific research monsters on Monster Mountain were collectively bewitched, frantically exploring this knowledge, and even fearlessly trying out the famous experiments recorded in those textbooks one by one.

For example, there was a silly kappa who tried to make a lightning rod experiment by flying a kite during a thunderstorm. When he was finally found, he was basically half-ripe and had been lying in bed for a whole month.

For example, there was a fool who used a giant prism to conduct an experiment to break down sunlight. He was so engrossed in it that he successfully caused a forest fire and was severely punished.

For example, there was a very imaginative and creative tengu who planned to conduct a high-altitude drop experiment using two iron balls of different weights thousands of meters in the air. As a result, the iron balls fell and almost killed someone...

During this period, the mountain of monsters was in complete chaos, with demons running rampant.

Because if you're not careful, you never know when a few iron balls might fall from somewhere, or a few javelins or flying vehicles might fly out from somewhere... it's just indescribable.

As for Rikako Asakura, she was on a higher level. She was using chemical reagents to prepare new drugs in the laboratory when a sudden explosion occurred during the preparation process, causing a toxic gas leak. The released super-toxic gas successfully knocked out a large number of tengu and kappa around the laboratory... It's just that these monsters are relatively tough and have high enough life force. Otherwise, if ordinary people played like this, who knows how many people would have died long ago.

This world is fundamentally different from the world Shi Bai lived in in his previous life. With the abundance of spiritual energy in the world, and the fact that the Monster Mountain is a rare gathering place of spiritual veins, the raw materials born here are many times more powerful.

Shi Bai felt that if Asakura Rikako continued to do this, she might actually create a zombie virus in the yokai world... So, despite her strong protests, he forcibly deprived her of the right to use the laboratory again.

Aside from all that, Shi Bai usually spends most of his time telling stories to lolis like Aya Shameimaru, Momiji Inubashiri, and Suika Ibuki. He lives a very carefree and leisurely life.

Hmm... although it seems like there's a demon loli who's several thousand years old mixed in here...

P.S.: If there are more than 20 posts in this chapter before today, I'll release three chapters in a row! (((*°▽°*)八(*°▽°*)))?

Chapter Thirty: Physics to the Heavens and New Chapters

Thanks to the science textbooks kindly provided by Shi Bai, Monster Mountain thus entered the era of the first great technological revolution.

Although no results are yet visible, and all that remains is a technological mutation called a scientific experiment that is wreaking havoc on the entire Monster Mountain, the future is already imaginable as time goes by.

After nearly being hit on the head by a falling iron ball, Shi Bai, believing that his young heart had been hurt and needed time to recover, went off to hang out with a bunch of little girls.

There's no way to deal with these kappa researchers who claim to be dedicated to science; they're simply not to be trifled with. I've heard that some of them have already started organizing round-the-world trips, wanting to prove with their own actions that the Earth is a sphere...

However, recalling Ibaraki Kasen's promise to travel around the world, which has been going on for countless years and who has yet to return, Shi Bai felt that the chances of these kappa returning safely were extremely slim.

Although Asakura Rikako seemed eager to drag him into the research and expressed her deep regret that his talent shouldn't be wasted on frivolous fun, Tokihaku resolutely refused.

Are you kidding me? Even though I'm a top student, nothing beats being with cute girls!

So much time has passed, and the Old Hell has been opened. However, because she needs to guard those vengeful spirits, Hoshiguma Yuugi still stays in the Old Hell most of the time, while Ibuki Suika has plenty of time to come out and play. This is why Hoshiguma Yuugi never appeared in the previous war, because she had a more important mission.

Just as oxycodone chose to be imprisoned in hell, Hoshiguma Yuugi naturally wouldn't choose to abandon the responsibilities he bears.

Sometimes, Shi Bai would choose to go to the Old Hell to drink with Hoshiguma Yuugi, and also secretly visit the two little ones in the Earth Spirit Palace. With the care of Hoshiguma Yuugi and Ibuki Suika, Xiao Wu and Renren's lives were relatively peaceful. At least so far, Renren had not chosen to close her third eye.

After secretly taking photos of the two sisters' pets, such as CatCar and Sky, under the pangs of conscience, the complete character encyclopedia of the Underworld Temple was officially completed. As for the potential impact when these obviously secretly photographed cards are released in the future... well, I probably won't get killed.

Aside from that, Shi Bai spent most of his remaining time teaching his three best friends, Aya Inubashira, Momiji, and Hatake Himekaido, while also writing books in his spare time.

Perhaps because they had personally experienced war, the three of them had become much more mature than before. Although Aya Shameimaru and Kaidou still argued constantly, anyone could see the changes that had taken place in them.

As for Inuzoku Kaba... Shi Bai discovered that this white wolf tengu seemed to have become even dumber than before.

"Mechanical armor? How could you possibly have such a strange idea?"

Looking at Asakura Rikako, who was wearing a white coat and holding a junior high school physics book, Shi Bai's expression became rather strange after hearing her explain her purpose for coming.

Are these things taught in elementary and middle school textbooks?

"Scientific research is endless, and the most important thing is imagination. Imagination is the most important thing."

Rikako Asakura pushed up her glasses with her fingers, a glint of wisdom in her eyes.

"Thanks to your valuable teaching materials, I have developed a series of powerful equipment that is driven entirely in a non-magical way. Would you like to try it?"

"...Just these basic textbooks?"

Shi Bai's lips twitched slightly as he looked down at the physics textbook the other person was holding.

"How far have you gone?"

"It is possible to fly into the sky using pure scientific power."

Rikako Asakura pushed up her glasses again, a glint of shrewdness flashing in her eyes.

—Shi Bai later realized that this was a habitual cover-up that the other party would make when they wanted to deceive someone or set a trap for them.

"How about it? Would you like to try out the equipment I developed?"

"Flying into the sky... let's give it a try."

With mixed feelings of regret that he had wasted his time studying and being a top student, Shi Bai nodded.

Ten minutes later, at an open space on the Monster Mountain.

Are you sure this thing can make me fly?

Turning his head to the side, Shi Bai looked at the ordinary backpack that Asakura Rikako herself had named the "Rocket Jet Backpack" on her back, with a look of suspicion on her face.

"That's right, this is the piece of equipment I'm most proud of."

Rikako Asakura pushed up her glasses and took a few steps back without making a sound.

"It's very easy to use. See the button on the watch you're wearing on your wrist? Just press it."

"That's it..."

"boom--!!!"

With a loud bang, someone caught off guard was blasted into the air by the suddenly exploding backpack...

"Hmm...it seems we need to make further improvements. This backpack is only for one-time use and is completely unusable..."

While looking up at the sky and calculating the altitude and distance of this flight in her mind, Rikako Asakura took out a pen and paper and quickly wrote down various parameters.

"However, for the next experiment, it seems the gunpowder loading capacity can be doubled..."

................................................

"I was wrong!!!"

Rikako Asakura knelt obediently on the ground, prostrating herself completely to express her deepest apology.

"If it's an apology, then it's common sense to take off all your clothes when you apologize, right?"

Looking at the rather sensible Asakura Rikako in front of him, Tokihaku's face was as black as the bottom of a pot.

He was naturally immune to injury, but this was the first time he had ever experienced being physically launched into the sky like this... What the hell is this "rocket jetpack"?!

"Take off all your clothes? I get it."

After a slight pause, Rikako Asakura suddenly realized what was going on, and without thinking, she put her hand in front of her chest and started unbuttoning her clothes... Someone immediately stopped her with a chop to the neck.

"Tell me, why did you deliberately try to trick me?"

Even after accepting the tea that was politely offered, Shi Bai still appeared quite annoyed.

"Uh... because the other brave researchers have already filled the wards..."

Rikako Asakura turned her head away, feeling slightly guilty.

"truth."

"Because you won't let me into the lab, and you're strong enough not to get hurt in these kinds of experiments, and you're also the most approachable person, the one most willing to do these things with me."

Rikako Asakura gave an honest answer.
