My seven demon sisters

Somewhere in a closed underground laboratory.

In the dim and dim light, the girl with short white hair was excitedly scanning the old scroll in her hand.

She is the girl who mocked Rurika and Ayaka at the "Sword Dance Festival" before.

At this time, the corners of the girl's mouth suddenly twisted into a terrifying smile, as if she had made some new discovery.

The bloody pupils glowing red couldn't help but make people feel cold in their backs.

"Ah~ Maybe this method is feasible~ Hehehehe..."

As she spoke, the girl excitedly picked up the box on the table, turned around and walked towards the dark room.

After entering the room, the girl could no longer control her emotions.

She covered her blushing face and said with a sick face: "Ah~ah~ It's not good... I'm so excited~ Hurry up... Let's hurry up and experiment..."

As far as the eye could see, the walls of the room were covered with various eerie portraits, and the floor was painted with blood-red forbidden charms.

On the shelves on the side are a row of densely packed test tube racks, filled with all kinds of bizarre biological specimens.

In the far corners, several large glass containers are piled up, each containing an unformed test subject.

Gigantic miniature creatures... A fierce beast with the characteristics of insects... Animals with human faces... It's all creepy stitching monsters....

And these test subjects... The moment he saw the girl, it was like seeing death, his originally dull eyes suddenly trembled, and his body began to writhe violently.

Even if they've long since lost their minds... But under the torture of the maiden... As long as I see her, I will still instinctively feel fear...

It can be seen how tragic the girl's experiment is...

At this time, the girl opened the box in her hand and took out the purple-black prismatic fragment from it.

The shard, like a living creature, slowly floated into the air, and its surface began to squirm continuously.

Then, several black rays of energy burst out.

At the same time, the girl's body was also filled with the same black energy as the fragment.

Two pitch-black tentacles stretched out of her back... Then he stabbed towards the two nearest containers.

I heard a cry of pain coming from the room.

The two test subjects were ruthlessly dragged out by her.

"Hmm... It is written on the scroll... Letting the subject touch the artifact at the same time - the "Calamity Box" will most likely increase the stability after fusion~"

As she spoke, the tentacles behind the girl shook violently, smashing the two test subjects into the fragments floating in the air.

With a deafening scream, the bodies of the two subjects began to gradually disintegrate under the influence of the black energy... Melt... Reorganization....

In the end, it fused into an even more exaggerated stitching monster...

However, in the next second, the stitching monster began to swell... Then it burst like a balloon... Moment... Blood splattered all over the room....

"I hate it~ It's useless at all. Could it be because the artifact is incomplete?".

Looking at this miserable picture, there was no trace of turmoil in the girl's heart... I just took the fragment back into the box with a look of regret.

At this moment, two footsteps from the door immediately made the girl excited again.

Walked in... It's the blonde and brunette who attacked Iori before....

"Lord Lavina... I'm sorry to excuse you..."

, the blonde knelt on one knee and respectfully addressed the short-haired girl known as Lavina.

The brunette on the side also knelt down with her.

Lavina covered her face and twisted her body excitedly: "Hehe~How is it??people?I can't wait!

""Really... I'm really sorry... Lavina... My lord... I... Missed..."

"?...? ....? ....? ...???? "

Listen to the brunette... Lavina's body froze directly.

"That is to say... Gone?... Gone?... Gone? Gone? Gone? Gone, my experiment can't be done?..."

"Ravena-sama... You listen to me explain... That snake girl... It's not an A at all—"

The brunette was only halfway through her words... I saw Ravina with a hand knife...

Eh?...

World... How to turn the ?... upside down

This is... How.... Return.... Thing-boom

....

With a muffled sound....

The next moment... The brunette is already the head of the person separated ... The headless torso fell like this....

The blonde woman on the side was directly stupefied by this scene... Her body began to tremble uncontrollably...

"What about the waste... Rubbish... Rubbish... Rubbish... Waste! Even the weakest of the Seven Sisters can't handle it... My experiments... What about my experiments!?

Lavina leaned back, clutching her head in pain and howling.

"Ah~Forget it~ I have to endure it for a few more days~ Anyway, after the match, I can attack them~Hehehehe~"

However, after only a few seconds, Ravina seemed to recover from the collapse.

Seeing that Lavina was relieved, the blonde secretly breathed a sigh of relief in her heart. This time, I can be regarded as escaping.

"That's... Mistress Lavina... Forgive your subordinates for their ignorance... Why are the people above so obsessed with the study of 'artifacts'?...

" Lavina smiled after hearing this: "Hehe~ Of course, it's to fight against humans." "

Confrontation ... Mankind?... IMHO... What the hell is there to be afraid of in those inferior species?..."

The blonde woman looked incredulous.

"To say that you are ignorant seems to be really ignorant. Do you think that the War of the Three Realms a hundred years ago ended just because of simple negotiations?"

"This..."

Speaking of this, the corners of Lavina's mouth once again showed a touch of excitement: "Indeed, humans have no superpowers and magic, and their physical fitness is far lower than that of gods and demons~ but-"

As she spoke, Lavina spread out her hands and gestured in a huge arc.

"The weapons in their hands are more powerful than any~ any ability and magic~ So, some people are very unhappy. They think that this kind of weak species that can only play "clever" is not qualified to be on an equal footing with themselves~

" "Teachable... Thanks to Lady Lavina, my subordinates understand... In other words, do the people above want to make up for the gap in strength through the power

of the 'artifact'?" "Yes~ Although I don't care at all, I'm just interested in studying these things~ I'm also quite interested in human technology, but they limit the sharing of technology. What a pity~"

Lavina happily spun around in place, then picked up the box on the table next to her and handed it to the blonde.

"This is today's test, as usual.

"Yes. The subordinates will go. After

taking the box, the blonde figure disappeared in an instant.

After a long ——————

, the blonde arrives at an underground black market, blends in with the crowd, and eventually enters a bar.

However, all of this was seen by a figure in the dark.

As the night light shines, the shadows in the dark gradually become clear.

It is colored leaves.

"Ahh
