I planted a sacred tree in Tokyo.

Chapter 326 Yin Dun Creation
Ding, ding, ding,

Along the Kamo River, which runs through Kyoto City, the sounds of dense and noisy hammering can be heard incessantly.
A massive ironworks was billowing thick smoke, forging weapons and armor day and night.

However, what was being forged was not human machinery, but rather 'ghosts' that were three meters tall, muscular, wearing tiger-skin skirts, with blue faces and fangs, and with shackles on their hands and feet.

In the supernatural tales of the island nation, "oni" specifically refers to a race of demons with strong bodies and immense strength; those monsters collectively known as "hundred demons" are mostly spirits and evil spirits. And those who can control the demon race to forge are naturally no ordinary beings.

It's easy to tell from the 'Gentian Flags' planted around the ironworks that this is 'Genji' territory.

The name Genji means "of the same origin".

The royal family of the island nation has been in an unbroken line for generations, and the emperor does nothing but eat, drink, be merry, and make babies.

It's not a big deal if you have dozens of children with certain emperors who are 'naturally promiscuous'.

In this situation, the national treasury was unable to provide for them, so the custom of "bestowing surnames to serve as subjects" came about. All those who were given the surname "Minamoto" proved that they were once princes and nobles: these Minamoto descendants left Heian-kyo and established samurai groups in Settsu Province, which is Osaka, and later dispersed to various parts of the island nation, becoming the source of most samurai families.

Therefore, in the history of island nations, most of the 'daimyo' (feudal lords) can be traced back to the imperial family through their family genealogies.

Boom, boom, boom, boom!

A child carrying a giant axe walks among a large number of 'evil spirits'.

The child was chubby, with a hairstyle like a straw hat, and wore only a red bib with a large "gold" character embroidered on it. Although he was just a child, the ground shook when he walked. The evil spirits, known for their superhuman strength, seemed to tremble in fear in his presence and stepped aside.

This character is a household name in Japan and frequently appears in children's books.

"Master of the Household,"

The giant axe boy walked to the center of the ironworks and bowed to a figure with long white hair.

"Kintaro, you've arrived."

The white-haired man turned around. He was dressed in a samurai outfit from the Heian period, with a simple breastplate and shoulder guards. The 'Gentian family crest' on his chest represented his identity.

The man looked down at people with his superior gaze, his face full of arrogance, making it clear at a glance that he was an ambitious and ruthless leader.

The head of the Minamoto clan, Minamoto Yorimitsu!

"Is there a problem?"

When faced with the child carrying a giant axe, Minamoto no Yorimitsu asked him gently.

"Master, we..."

The child, known as 'Kintaro', hesitated for a moment before finally asking the question that had been bothering him.

"Whom are we going to use the Ghost Army Department to deal with?"

The Demon Army is a secret technique of the Minamoto clan, powered by the flesh and blood of demons, with a steel body as its shell and the soul of a samurai as its core; it creates a tireless, fearless, and eternally loyal army.

These were once the weapons the Genji used to suppress all kinds of demons, but now they are being forged to fight against—

Is it 'human'?

Kintaro, the child carrying the giant axe, lowered his eyes.

He is one of the 'Four Heavenly Kings of Genji', a guardian deity of children in Japanese legend; but what should he do if his master wants to slaughter humans?
"Ha, Kintaro, have you forgotten the promise we made?"

The white-haired samurai smiled and asked in return.

"I haven't forgotten!"

The child named Kintaro shook his head vigorously. Since his "resurrection" from the underworld, he had been diligently fulfilling his duties. Although many memories had become "blurred," he had not forgotten that one sentence.

"Master, you once said: One day, the banners of humanity will be planted all over this land, standing above even the gods and spirits!"

This is Minamoto no Yorimitsu's ideal, and he is willing to stop at nothing to achieve it.

Weapons of war are forged from the corpses of demons and the souls of samurai!
That is why the Four Heavenly Kings followed him.

"I haven't forgotten either,"

'Minamoto no Yorimitsu' looked around and then looked at the 'Demon Clan' who was constantly forging and hammering.

“I know what you want to say, Kintaro.”

"We can no longer be considered 'human' anymore. Are you worried I'll attack humans?"

After all, he was a subordinate whom he had personally 'shaped', so 'Minamoto no Yorimitsu' knew exactly what Kintaro was thinking.

“You underestimate me, and Seimei underestimated me too. I, Minamoto no Yorimitsu, have never been a ‘good person’; but what I am determined to do, even the gods cannot stop or change!”

Expel ghosts and spirits, annihilate demons, and humankind will reign supreme!
thud,

Drop the giant axe,

The child wearing a bib immediately knelt down.

"It was I who presumptuously doubted the head of the family; I deserve to die!"

"It's not your fault. It's the duty of a servant to point out the mistakes of his master. Go and do your work."

"Yes!"

I received the head of the family's answer in person.

With his doubts dispelled, Kintaro happily went to supervise the forging of the Oni Soldier Department.

“What a simple 'spirit',”

Minamoto no Yorimitsu smiled and shook his head, then habitually raised his hand to rub his temples.

"However, I'm not lying. These demon soldiers weren't originally meant to deal with 'humans'."

These demon soldiers, and this 'Heian-kyo', are all places someone uses to practice their 'Yin-Yang Release' proficiency—the nature of Yin Release is creation, and many secret arts families, such as the Yamanaka, Nara, and Kurama families, specialize in the nature of Yin Release.

The most representative of them all is the Uchiha!

Once the Kaleidoscope is activated, Susanoo Gundam becomes a manifestation of creation from the void. Its Infinite Tsukuyomi can pull all the creatures on a planet into an illusion, so its power is self-evident.

The nature transformation of Yang Release is essentially the infusion of life force into a physical form. — For example, the Akimichi clan's Multiply Technique and the Senju clan's Body Healing Technique.

When Yin and Yang techniques are combined, they become the true power of the Creator.

For example, in his Six Paths state, the Crown Prince raised his hand to save Guy from certain death by using the Eight Gates, and waved his hand to create an eye for Kakashi.

Yu has been constantly practicing and researching with his clones. Now he is able to shape the remnants of souls in the underworld into physical forms and give them false memories. This is also why he only needs two clones and a huge number of 'evil spirits' as materials to build this huge 'Heian-kyo'.

"Unfortunately, it's just a change made to the 'raw materials'."

We are still countless miles away from the true realm of 'divine'.

Bunkyo Ward, Tokyo
In the 'Spiritualism' classroom of the Sorcery Academy,

That concludes today's lesson.

The teacher in charge of the lecture, Satoru Sakuma, put away his handouts and tried to maintain a calm expression.

Although he was also a superhuman, he still felt immense pressure facing a group of superhuman students. Unlike Mr. Yagyu, who possessed overwhelming swordsmanship skills, and unlike the principal, who was truly the 'strongest in modern times,' his lectures consisted mainly of intelligence gathered by the government and his own insights.

Fortunately, most of the 'students' seemed to be quite accommodating and didn't shout things like 'XXX, refund my money'.

"Ha, I thought he would have some profound insights to offer."

"Just a mediocre teacher who misleads students."

As soon as Dong Xiaomei stepped out of the classroom, an arrogant voice emanated from her.

With her delicate, girlish appearance, she might look like a little devil at first glance. However, in reality, she is a true demon queen!
"Sister Xinna,"

Dong Xiaomei spoke helplessly; she wasn't a particularly strong-willed person.

Having an extra strong-willed sister like Izuki inside her body was no big deal; now that there's an even stronger 'Oda Nobuna', she'll adapt just as quickly.

"Most of the students here are at the Wolf level, and the knowledge that Sakuma-sensei just shared is extremely useful to us."

"It's only somewhat useful for low-level psychics, there's no need to come again—"

"I do not want!"

To everyone's surprise, Higashimomi flatly refused.
"I've finally returned to school, and I'm determined to finish my three-year course."

?

Seemingly not expecting that Higashi Takami would dare to disobey her, Oda Nobuna raised an eyebrow, about to lash out.

"I object too!"

The spirit of high school girl Itsuki emerged from the other side.

"Shinnai, I don't care who you are. But Hsiao-mei's life should be her own to decide—if you're living in someone else's body, don't cause them trouble!"

? !
"You two—" "Hyomi, what's going on here?"

Just as tensions were about to rise, a soft voice came from behind.

Ryoko Miyashita, with her hair tied in a high ponytail but possessing the personality of a traditional girl, walked over hesitantly, her fingers twisting together as she whispered words of advice.

"Let's talk things out calmly and not argue."

"Arguing will only escalate the conflict and eventually lead to parting ways."

"Humph,"

"What you want to do is your business."

Someone interrupted, and Oda Nobuna waved her hand listlessly before shrinking into Higashi Takami's body.

She didn't consider herself Oda Nobunaga, but she was just as clear about Nobunaga's 'life': being too self-centered led to being betrayed by her subordinates and dying in flames.

If Nobunaga had communicated with Azai Nagamasa, his sister Oichi wouldn't have been forced to remain a widow for life.
If Nobunaga had communicated with Akechi Mitsuhide, it would have been impossible for him to be burned to death at Honnoji Temple;

His domineering personality led to repeated betrayals by those close to him.

Did Nobunaga, engulfed in flames, ever regret his actions?

"what?"

"Teach us how to change the nature of Yin-attribute spiritual power?"

Upon returning home, both the high school girl demon Itsuki and the middle school student host Higashi Takami were shocked by Oda Nobuna's proposal.

"What's that expression on your face?"

Oda Nobuna, sitting on the sofa, raised an eyebrow.
However, after thinking about the fate of 'Oda Nobunaga', he suppressed his anger and explained.

“I’ve said it before, you are all my ‘vassals’!”

"Is it so hard to understand when a master rewards his retainers?"

"No, not at all,"

Higashi Takami quietly made a gesture, signaling Izuki not to speak yet;
Izuki also has a strong personality, and she would start arguing with Oda Nobuna after only a few words.

Is it because of the daytime classes?

After thinking for a moment, Dong Xiaomei gave a reason that she thought was possible.

"Shinna-nee thinks the teacher's level is too low,"

So you couldn't help but teach them yourself?

"You can think whatever you want,"

Shino sat cross-legged on the sofa, one hand supporting her chin, the other hand waving casually.

"Watch closely, the change in the nature of Yin attribute spiritual power—"

As she spoke, she opened her palms.

A long sword appeared out of thin air above his palm, with its hilt, guard, and blade.
Snapped,
Next second,
A gleaming samurai sword appeared out of thin air.

"then,"

With a shout, Oda Nobuna threw her katana to Higashi Takami.

"Hey?!"

Despite being flustered by the flying samurai sword, Higashi Takami managed to grab the hilt with precision, avoiding injury from the thrown weapon.

"So, what does this mean?"

As the high school spirit Itsuki looked on in confusion, Oda Nobuna sighed and rubbed her forehead in exasperation.

"Fool!"

"Didn't you notice that the knife was a solid object?"

? !
Yes~~
The person and the spirit suddenly realized...
Most evil spirits are ethereal, so they are immune to any physical attacks.

Its attacks are also aimed at the soul; however, injuries to the soul will also be reflected in the body.

Upon reaching the Wolf level, the evil spirit can interfere with reality to a certain extent; for example, Izuki's 'rope' can suspend Higashi Takami and fly around; as its strength increases, it can even whip armored vehicles away. However—

This still doesn't change the fact that she is a 'spirit', and she will soon disappear once the rope on her wrist is cut.

The sword made by Oda Nobuna
Higashi Takami swung her sword a few times, and the clear sound of it cutting through the air declared one fact:
It is absolutely true!
"Homi,"

Sitting on the sofa, Oda Nobuna leaned forward slightly and spoke, pointing to the knife in Higashi Takami's hand.

"Try cutting something with this weapon."

?

"Ah, okay~~"

After looking around, Dong Xiaomei's gaze fell on the television.

brush,

With a gentle swing of the longsword, the television was split in two.

? ?
"So sharp!"

"Ah, this is my beloved knife, 'Katsu'."

As Oda Nobuna proudly introduced the story, Itsuki, standing next to her, almost reflexively mocked her.

"Is it the sword that, after you had a fight with someone while drinking tea, you cleaved the tea shop owner and the tea stall in two?"

"That's Oda Nobunaga, not me!"

Oda Nobuna rolled her eyes at Itsuki. She didn't know what to do with this 'fearless' spirit.

"Stop arguing, all of you."

The two powerful evil spirits within her body were giving Higashi Takami a terrible headache.

"The nature of Yin-attribute spiritual power can be altered—allowing for the creation of objects at will?"

Thinking back to the young principal's methods at the opening ceremony, Higashi Takami guessed the answer.

"That's exactly right,"

Oda Nobuna, leaning back on the sofa, had an expression that said, "She's a promising student."

"Advanced application of Yin-attribute spiritual power: Void creation, just like the rope on this blond guy's wrist, which is able to materialize."

"Tch, I thought it was something special."

The girl called 'this blondie' pouted unhappily.

"I can do it too."

She could only visualize the rope as a physical object, but she refused to back down verbally.

"No, Sister Xinnai, you mean: the change in the nature of Yin attribute spiritual power is not only about creating things from the void, but also about endowing them with certain characteristics?"

Higashi Takami seemed to be deep in thought. It was obvious that her television was not so fragile as to be easily slashed open with a knife; moreover, Higashi Takami knew very well that she had not used any force at all, relying entirely on the exceptional sharpness of the samurai sword in her hand.

"That's right,"

"This is the most important aspect of the change in the nature of Yin attribute spiritual power: bestowing upon it unique characteristics!"

In the Naruto world, when Itachi Uchiha and Sasuke were fighting, Orochimaru suddenly burst out from Sasuke's body and used the 'Eight-Headed Serpent Technique'.

However, Itachi, having activated Susanoo, first took out the 'Yata Mirror' which could deflect all physical attacks, and then pulled out the 'Totsuka Blade' which could permanently seal the target in its hilt, leaving Orochimaru speechless.

Neither the 'Yata Mirror' nor the 'Totsuka Blade' are abilities inherent to Itachi's Mangekyou Sharingan.

But -

The 'spiritual artifact' left behind by the former Mangekyou Sharingan Uchiha using Yin Release.

With the power of the Mangekyou Sharingan, one can completely imbue the 'Spiritual Weapon' with various effects: it's essentially a weakened version of the 'Six Paths Ninja Tool'.

"How about it?"

Oda Nobuna leaned back on the sofa in a boss-like posture with a smile on her face.

"To imbue weapons and armor that have been conjured from nothing with various properties—want to learn?"
