At the top of Mt. Yokai, the fog has gone, the mountain wind is blowing strongly, and only a castle tower stands on it.

I don't remember when there was this pavilion, but it was here before the tengu knew how to record their glory with pen and paper.

It's bigger than any human castle tower, but it's also more modest than any human castle tower.

Originally, the castle tower was built as a watchtower and castle, and it was also the residence of the castle lord.

For tengu, naturally there are no such curves.

The only people who can live on the top of Yokai Mountain are big yokai.

And the only thing that can live in the tallest building on the top of Youkai Mountain is naturally the Heavenly Demon.

It symbolizes the strongest, and that is enough.

As you go deeper into the castle tower, you will see its main entrance.

Those are two doors that are too large for a person, and if you look closely, you can still find those past sword marks on the door, and imagine the rise and fall of this pavilion for thousands of years.

Inside the castle tower is a very ordinary hall, the hall was originally very spacious, but now there are only two people.

A youkai, a shrine maiden.

They are not as strong as people.

So here they are.

"Why are you doing this?"

Hakuri Reimu calmly faced the chains that bound her hands and feet, her face was a little pale, and her hands were a little cold, but this did not prevent her from fulfilling her duties as a shrine maiden.

She asked, pointing to a hill in front of her.

Then on the hill, a voice rang out.

"A lot of things don't really need a reason and don't need a reason. It's as natural as eating and drinking, as pleasant as crushing an ant, it's the law of nature. 」

This voice exudes the meaning of neutrality and peace, but there is also a hint of weakness in it, and if you listen carefully, you can still hear her faint coughing up blood.

Xiaoshan is not a mountain, it is a demon, it is a heavenly demon. The strongest of Yokai Mountain.

The Celestial Demon's body was so large that the entire castle tower was just a prison for him to barely stand, and he was wearing a huge armor full of cracks, as old as the sword marks in front of the castle tower's gates.

"So I'm locked up here, watching every plant and tree in the world, flowers blooming and falling. 」

It probably touched the pain of the body, but the eyes were still warm, but it brought out a bit of reminiscence.

"I thought that I would be trapped in this pavilion forever for the rest of my life, but I didn't expect that now God has given me a second choice. 」

Bo Li Reimu said calmly as she looked at the Heavenly Demon.

"Your choice is for me to bear these sins?"

The Hakurei Shrine Maiden knows all the ways and has never had any problems in her cultivation, and Hakurei Reimu is regarded as the most talented and potential of the Hakurei Shrine Maiden in the past.

Now he was trapped on the top of Youkai Mountain for three days to atone for his sins.

Redemption naturally does not be an ordinary sin.

Hakurei Reimu glanced lightly at the bottom of her.

Beneath her were white bones, countless white bones.

With bones as a cage, so powerful, so terrible punishment.

……

……

"Are these bones your sins?"

Maybe the time was coming and he was about to get out of trouble, but the Heavenly Demon did not refuse to answer the witch's question, and said with a smile.

"It's a complicated story, of course. 」

Perhaps because of the anticipation in his heart, Reimu's reaction at this moment was very calm, and he said, "I want to hear it. 」

The Heavenly Demon was silent for a moment, and then recalled.

"The defeat in the Yuedu War directly changed the pattern of the world. In addition to the official retreat of the ghost clan to the underground, the demon world has also closed the passage to and fro. From that time on, the yokai officially went into decline. 」

"At this moment, we suddenly received the news that the princess of Yuedu and the sage were on the ground, and what made us enchanted the most was the elixir of immortality in their hands. 」

"The news spread very quickly, and it was a little unbelievable. But we didn't have time to think, and the anger after the defeat made the youkai ignore the rules of the world and choose to take action. That's where the story begins. 」

When this period of history came slowly, the tone of the Heavenly Demon was like a spring breeze, but the cruel pictures in the past were omitted from the words.

Hakuri Reimu looked at the white bones under his feet, thinking about the internal strife in the long story told by the other party, and said after a moment of silence.

"Greed has always been a shortcut to death. 」

The Heavenly Demon looked at her with full eyes and said with emotion.

"Look at you, you're the most promising of all the Hakurei witches of all ages, and you're also the one with the most potential to break through your fate. Why is your knowledge so short-sighted?Didn't the previous shrine maiden tell you what kind of power youkai had in the human world in the past?"

Hakurei Reimu has been a shrine maiden for no more than five years at most, except for a few youkai. In her eyes, most of them belong to situations that are not terrible, and even have some cuteness.

The Heavenly Demon's eyes slowly drooped.

"In addition to the tengu, the rain girl, the flying man, the kappa, and the snow girl...... There are tens of thousands of types of monsters. If it weren't for the fear of the gods' protection of humans, the youkai of those days would have been enough to establish a kingdom. 」

"But you failed. 」

The Heavenly Demon sighed, his sigh full of compassion, "We knew the news of the Princess's exile and the sage's defection, but we didn't expect him to come. Just because he came. 」

"He?"

Hakurei asked with a frown.

The Heavenly Demon was silent for a long time, and then laughed, and there was a complex meaning hidden in his smile, some emotion, some bitterness, and some pride.

Then his name was pronounced.

"Eight Meanings Sword. 」
