Under Reimu's watchful eye, Shiki begins to dig graves.

Soon the grave was dug up by Shiki, but what appeared inside was not the expected decomposing corpse.

"Huh?"

Reimu blinked and looked at the empty cemetery.

"No?"

"Yes."

Shiki fumbled in the dirt nearby for a while before finding a white strip-shaped object.

"What's that?"

"Bones."

"Bones?!"

"Yes, there are tooth marks on it, it was gnawed like this."

As he spoke, Shiki found some bone fragments around him.

"The corpse was eaten."

"This shouldn't be the work of a wild dog, right?"

"Nope. It's something else. ”

"How did this strange thing happen lately?"

Reimu frowned.

Once the situation had been determined, Shiki and Reimu buried the scattered bones back in the ground.

"It's miserable."

As she collected the bone fragments, Reimu muttered.

"What do you mean?"

"It's just that the corpse has become so tattered."

"Really? When human beings bury their bodies in the soil after death, they will naturally be decomposed by microorganisms, and these decomposed parts are integrated into the soil to become nutrients for plant growth, and then animals eat plants, and humans eat animals, which is the ecological cycle. I don't think it's a miserable thing. ”

"Hey~~~?"

Reimu looked at Shiki with some surprise, and she could sense that Shiki was serious.

"Ecological cycle? I don't understand. ”

Reimu shrugged.

"Anyway, it's not a good thing to be eaten by that monster, right?"

"Indeed."

Thinking of what would eat the corpse, Shiki nodded in agreement.

"Rest in peace."

After the event, Shiki and Reimu put their palms together and prayed at the grave.

"You know what it is that eats corpses?"

"Got it."

"Really? It can't be a ghoul, right? ”

"It's a ghoul."

“……”

Reimu's expression stiffened.

"It's a ghoul."

"I hear you clearly."

"That's good."

Shiki didn't care about Reimu's expression either.

He had just found the ghosts that had eaten the corpses and the mouths of the villagers from the memories that remained around him, it was a creature very similar to humans, it also stood on two legs, but its body leaned forward, some like wild beasts, and its body was also somewhat deformed. And judging from its habits, it is most consistent with a creature like a ghoul.

"I'm going to follow the traces left by the ghouls. Reimu together? ”

"Of course!"

So the two walked out of the cemetery.

The seasons followed the ghouls' tracks and the memories that lingered around them, and soon came to a distance from the village.

According to the knowledge of the four seasons, this area is supposed to be the Magic Forest, and the dense trees around it gradually obscure the day, making the place look gloomy.

The seasons stopped.

"What's wrong?"

"There's no trace of it."

The surrounding environment is too complex to find footprints, and memory remnants are also affected by complex environments, generally speaking, it is not easy to save one day, and it is already the limit of the four seasons to be able to trace it to now.

"No clue again?"

"Hmmm......"

Shiki looked at the forest around him, he and Miyuki had been to the Magic Forest before, but they had entered from a completely different direction, and now it was relatively uninhabited, and the forest was more primitive.

"It's weird."

"What's weird?"

"Ghouls feed on human corpses, and if there are no corpses, they will attack humans, but if they need humans anyway, then they should not go far away from people."

"It's really strange that there will be no one here in general, it is indeed strange that something is attracting ghouls, just like the fire spirit last time."

"What's near this forest?"

"Around here?"

Reimu thought about the question of the four seasons, then flew to the top of the tree and looked around, and when she returned, her face was not very good.

"There's really a place around here that might attract ghouls."

This answer did not come as expected by the four seasons.

"Let's go."

This time, it became Reimu to lead the way, with a clear destination, and they flew directly in the air.

"Where are we going?"

On the way, Shiki asked Reimu.

"Think again."

Reimu uttered a term that the seasons were unfamiliar with.

"Walk through the Forest of Magic, and then through the path, you will reach the Tomb of Nothing. It is a cemetery for the untouched, and suicide victims from the outside world often get lost in it. Because it is a remote area of Gensokyo, it is easy for people from the outside world to come in. In autumn, the path of rethinking will be full of flowers, and those who want to commit suicide will be poisoned when they walk on this path, and the painful and unpleasant experience may give birth to the courage to live. That's why that trail is called the way of rethinking. ”

"I see."

Shiki understands Reimu's reason why this place attracts ghouls, and if someone from the outside world appears there, it can easily become a prey for ghouls. In addition, after knowing the location of the Missing Mound, it is likely that those ghouls were hiding there before.

"Reimu, have you ever been to the Void Tomb to investigate before?"

"No, there's no one there. Do you think this is also related to the Demon Book? ”

"It just so happens that other species have entered Gensokyo, which may also exist, but the timing is too coincidental to get rid of the suspicion of the demon book, after all, there are still some books that have not been recovered."

"Ahhh~~~ That's enough! Are the questions of those books endless? ”

"It's just my speculation."

"When you go back, you must reprimand Xiaoling again!"

But Reimu can't listen to it anymore.

As they move on, the area of the Forest of Magic is huge, and the Way of Rethinking and the Tomb of Nothing are in the remote area of Gensokyo, so it will take a while to get there.

Just as they saw the end of the forest from a distance, they suddenly noticed that the yin qi around them had become heavier. It was not because of the darkness caused by the lack of sunlight, but because of the dead man's death.

Shiki quickly glanced around, and noticed that there were many ghosts floating in the nearby forest.

"Is that usually the case here?"

"How is that possible?"

Reimu vetoed it flatly, meaning that this was not a normal situation.

"Really! The ghouls haven't been solved yet, and so many ghosts have escaped! ”

As Reimu complained, a figure flew at high speed over the forest not far away.

It was a girl with short silver hair, dressed in a green dress with two katanas tied around her waist, and even more peculiar was a half-human-sized cloud-like ghost floating around her.

Because it's a famous character in Gensokyo, Shiki immediately recognized that it was a half-human, half-spirit girl.,Soul Demon Dream.。

"Wait a minute! What the hell are you doing? ”

The moment she spotted the suspicious (Reimu perspective) guy, Reimu immediately rushed forward
