"Ha, even you can finally make that kind of expression?"

"...If you really intend to provoke me."

The two stood facing each other.

And that demon, finally, developed emotions that only lowly humans like them could have.

"Well, at least you managed to do that."

It raised its hand, intending to twist the other's body in two.

For an instant.

—In the void, something else suddenly appeared.

Bang! ! !

What was forcibly blasted into the earth was something like a crack.

But emerging from that crack was another colorful radiance.

"Varied--?"

Accelerator and DO Apis both showed expressions of surprise.

Boom!! The demon was instantly blasted away by the colorful light that shot out.

It seemed utterly powerless to resist.

"Hee hee—! Finally, we've finally reached the end~!"

A soft thud—the sound of something hitting the ground rang out.

That wasn't the one who attacked; rather, the power possessed by that figure was far less than one-tenth of that of Accelerator.

Her body was not actually in a human form.

"It took about half a day to finally get here from another timeline!"

It has tentacles with suckers like an octopus, white wings, hair and the top of its head look like a jellyfish, and there is a small hole in its forehead. Its clothes look like they are made of newspapers pasted together.

But no matter how you look at it, she is still a young girl.

Accelerator kept a close eye on her, but did not let his guard down in the slightest.

"what are you?"

He even forgot that his hands were too weak to move, yet he still struggled to his feet and glared fiercely at the other person.

Otherwise, it might mean having to fight two enemies.

"Ugh, being treated like a stranger by the master is really not a good feeling! The master in this timeline is really in a tough battle, ugh... that guy named Yun something, since he brought me here, he should at least take care of the master's current nemesis!"

Owner?

What on earth is this incomprehensible creature saying?

"Well then, nice to meet you, Accelerator."

However, she still introduced herself.

This strangely-looking girl, clutching her skirt with both hands, performed a slightly ornate ceremony that contrasted sharply with her bizarre appearance.

"As I said, you are my master, and I... am the demon who has made a pact with you."

"—'Qliphoth545,' but that's too long. Just use the name you usually use for me, Master."

She spun around in place and smiled happily, showing her teeth.

"Just call me Q Demon! Hehe~"

Chapter 510 The Reverse Source Puzzle 545 (Qliphoth 545)

Gensokyo suffered devastating destruction.

And the source of that destruction is right here.

only.

Aside from DO Apis as the attacker and Accelerator as the defender.

Another figure then appeared here.

"An inverse source material puzzle... what is that?"

Words whose meaning is unclear to Accelerator.

This is not a scientific term, nor is it related to Gensokyo. Rather, it is unreasonable for such a girl to suddenly appear on such a dangerous battlefield.

The girl in front of him had a different name for herself.

--demon.

Just like the demon that represents the true abyss, they are the same race.

"The correct interpretation should be the Tree of Evil, which represents the inversion of the Tree of Life by using ten spheres and twenty-two paths to control the reverse world."

"what?"

"The tree that angels guard is called the Tree of Life, right? And the tree that is completely reversed and symmetrical is the Tree of Evil. Using the channels that the Tree of Evil possesses, whether it is the vast knowledge hidden on the other side of the world, or sinking into the distorted fog, it can all be done by relying on the power of the Tree of Evil."

Accelerator was completely baffled by this.

He had no idea about the Tree of Evil or the Tree of Life. Although he possessed an immense amount of knowledge, as someone born into a scientific background, he didn't pay much attention to information or knowledge related to the occult.

However, he did manage to read religious books such as the Bible carefully.

So you can hear some similarities.

For example, the positive tree of life, guarded by angels, capable of guiding the subject to the sacred path of this world.

"You... are from the realm of magic?"

Although he didn't know the specific meanings of these words, he immediately connected them to related information based on what the other person said.

In his memory, those involved in these matters were mostly magicians from his original world.

But that only made the girl in front of him look surprised.

Because that would mean that the person in front of you could analyze a whole lot of information based on just a few words.

"Huh...? Master already... knows so much?"

"And what about that 'master'? You said you were a demon, right? What does that mean?"

"Well, this is a long story... um! I'll make it short—"

The demon girl, who called herself "Qliphoth545," then became flustered, waving her arms and looking somewhat at a loss.

At the same time, Accelerator's eyes immediately started moving.

Boom! The crimson flames transformed into a slash, rushing towards the demon girl.

Without hesitation, he took a step forward and charged ahead.

Boom! A purple-black current of electricity rippled and formed in front of his body.

Unlike the invisible state of the past, this reflective film presents a dark, fluid appearance.

Even the attack from that abyss demon was deflected and bounced back along the same path.

However, this resulted in further physical damage to Accelerator.

"As expected... it's still a stretch."

Drip. More blood flowed down his arm.

His original level 5 superpower was simply not enough to reflect the abyss demon's abilities.

By further enhancing his superpowers using this unknown attribute, Accelerator was able to successfully deflect DO Abis's attack. However, in reality, he was like someone who had swallowed a date whole, unaware of the principles behind the analysis process. It was as if the ability itself was ignoring his will and proceeding with the analysis.

He was unable to properly control this force, nor could he take care of the burden on his body.

"Ha, it seems they don't intend for us to continue chatting."

"Eh--?!!"

The two looked up and saw a huge black figure slowly approaching them.

"I don't know where you came from, but you don't really think that turning one into two will make you stronger than me, do you?"

DO Apis, a monster powerful enough to easily destroy any world, doesn't care about the appearance of one more person.

Even if "Qliphoth545" is there to help Accelerator, it still won't bring any hope.

Because this petite girl who calls herself a demon possesses attack capabilities far inferior to Accelerator himself.

Even if you add a bucket of water to a lake, which is already far less vast than the ocean, the fundamental difference remains unchanged.

"Master! Are you... alright?!"

"...What exactly are you doing here?"

"Ah... well, I'm here to help you! Although I don't know the specifics, the person who brought me here said that you, my master, are about to face a great disaster..."

Before "Qliphoth545" could finish speaking, another burst of light struck.

Before the attack arrived, Accelerator grabbed her hand and flew with her into the sky at supersonic speed.

Boom——! ! !

Behind them, a hill had been destroyed.

This is nothing to DO Apis. It was able to shatter dozens of meteorites the size of Earth with a single blow, which means that it could easily destroy the entire Earth with a flick of its finger if it wanted to.

The reason it didn't do that was simply to demonstrate its absolute control over power.

Fortunately, Accelerator's powers were still intact, and in the critical moment, he grabbed the demon girl behind him and escaped into the air with her.

"Waaaaah...!"

"Ahem... Well, the thing is, I've already encountered a huge disaster, can't you tell?"

Accelerator used his ability to cough up all the stagnant blood in his body.

Forcibly moving his body still made his hands and feet very uncomfortable. His right arm had already suffered the negative effects of the previous "Doomsday Destroyer" super skill. Although the side effects of the time generator had been forcibly offset by the power of that abyss demon, it did not mean that Accelerator was in an easy state now.

Such a battle is already extremely difficult, and if you also consider the demon girl who can only panic after you take over, the battle becomes completely hopeless.

"So tell me, how exactly do you plan to help me?"

"Um...would you like to hear the reason first? Well, because I'm from a different timeline..."

"No need! Do we even have time to explain these trivial things now?!"

The first roar completely stunned the demon girl.

He's right, there's no time left.

The demon DO Apis has been waiting, eager to see just how far Accelerator can go now.

If the other side wanted to, they could easily destroy everything here at any time. The reason they didn't do so was simply to allow Accelerator to unleash his full power.

Therefore, there really is no time to care about the causes and consequences.

All he needs is the final conclusion.

"Tell me, demon! What is the way to defeat that guy? How can I gain enough power to completely crush that damned bastard? How can I protect everything around here?!"

The string of words left the girl stunned and speechless.

This was different from the owner she remembered.

Although the tone was equally intimidating, equally forceful and domineering.

However, the person in front of me seems to be more considerate of those around him.

He wasn't fighting solely to achieve his own goals; rather, he was fighting to protect these complete strangers.

This is different in some details from the first person she knew.

but.

This somewhat unexpected personality caused the girl, who was actually a demon, to smile.

Please call me Q Demon.

"Ah...anything is fine, Q Demon, please help me."
