It was pitch black in the dim underground passage.

A small figure was running fast in front, and behind it, another figure was chasing closely.

“Swoosh! Swoosh!!”

Purple magic bullets were shot out from time to time, hitting the small figure in front. The small figure struggled desperately, trying to escape the pursuit behind. However, no matter how hard it tried, it could not escape the pursuit. From time to time, magic bullets passed by it, leaving blood marks on its body.

This scene also appeared in front of Fang Zheng and Zhi Shi through Xiao Hei's personal terminal.

"It seems we are not the only ones looking for this thing."

Looking at the little white animal running fast in front of him, which was already covered with wounds, Fang Zheng couldn't help but sigh, and Zhishi nodded.

"Really, it looks pretty pathetic when you look at it that way."

Just as Zhishi said, at this moment, the strange white animal on the screen was already covered with wounds, and even its movements were not so agile. However, the hunter behind it still had no sympathy, but fired one magic bullet after another, trying to destroy it.

"Teacher, that child must be the magical girl we met before."

Tomoyo stretched out her hand and pointed at the magical girl who was chasing the white animal on the screen, and Fang Zheng nodded.

"Yes, it's her... It seems that we are not the only ones who found that the guy named QB is not right... But now we don't know if this is QB."

At this moment in the picture, the little white animal has rushed into a ventilation duct and is trying to escape. Not only that...

"Big brother, someone is coming!"

Through the search on his personal terminal, Xiao Hei also immediately discovered something unusual. Soon, a pink-haired girl came over, looking around. She looked like she was looking for something. It seemed that this was not just a simple mistake.

"What now?"

"Go and bring that white thing back. Sakura and Illya will go to support you. If there is any problem, open the barrier and go directly to the sky. Nanoha and Fate will support you there. Remember, considering how dangerous this thing is, don't be too careless."

Faced with the current situation, Fang Zheng quickly issued orders.

"learn!"

At this moment, in the underground passage, Kaname Madoka was still looking around in confusion.

Just now, she and her friends were enjoying music in a CD store not far away. But at some point, a voice for help suddenly rang in her mind, and it was this voice that attracted her. Kaname Madoka came to this closed place that was under renovation.

"Is there anyone? Who is calling me?"

While walking cautiously in the dim corridor, Kaname Madoka shouted nervously.

“Ka la…Ka la…”

However, at this moment, the ceiling above the girl's head not far away suddenly fell down, and then a white, bruised little animal fell heavily to the ground along with the ceiling.

"ah--!"

Seeing the little white animal falling from the sky, Kaname Madoka screamed and rushed forward to try to save it.

However, at this moment, suddenly, a series of flashes of cold light appeared, and then several huge sword blades fell rapidly, forming a cage, locking the little white animal inside.

Then, Kaname Madoka was surprised to see a girl with long silver hair, brown skin and wearing strange clothes appeared out of nowhere and stood in front of her.

"Excuse me, big sister, this place is off-limits. We are on a mission. Can you please leave?"

Xiao Hei looked at the pink-haired girl in front of him with a smile, and facing the sudden appearance of Xiao Hei, Kaname Madoka was obviously quite surprised. She instinctively took two steps back, but at this moment, the white little animal made a few sad cries. Hearing this sound, the pink-haired girl stopped again.

"Well, that... that child is seriously injured. Shouldn't we help him? At least, we should let him recover from his injuries first..."

As she spoke, the pink-haired girl tried to bypass Xiao Hei and rescue the white animal. However, just as she took action, Xiao Hei immediately waved his right hand, and the next moment, a sharp blade was pressed against the pink-haired girl's neck, preventing her from taking any further action.

"Big sister, don't meddle in other people's business. This is not a matter for you to interfere in. You are just an ordinary person. If you ask me, you'd better leave here immediately."

“Ugh…ah…”

Looking at the silver-haired girl in front of her and feeling the cold blade against her neck, Kaname Madoka gasped. At this moment, her desire to survive as a human still prevailed. Under the threat of Xiaohei, Kaname Madoka finally slowly backed away.

"very good."

Seeing that Kaname Madoka was obedient, Xiao Hei smiled playfully and put down the dagger in his hand.

"So what's next..."

“Crash!”

However, before Xiao Hei could finish his words, he heard the sound of chains, and then another figure jumped down from above. Seeing this figure, Kaname Madoka's eyes widened in surprise.

"Humura!!"

That's right, the person who appeared in front of Madoka Kaname was the transfer student Homura Akemi who had just transferred to their class today. However, Homura Akemi was wearing strange clothes at the moment. She just stared at Madoka Kaname coldly without saying a word.

"Ah, it's you, the black-haired big sister."

At this moment, Xiao Hei also noticed Homura Akemi and greeted her with a smile. Homura Akemi looked at Xiao Hei and frowned slightly.

"It's you..."

"Yes, it's me. Big sis, you're here to look for this thing too? It's called... QB, right?"

"Yes."

"That's good."

After hearing Homura Akemi's answer, Xiao Hei finally breathed a sigh of relief.

"Our eldest brother wanted to ask it something, and I thought it would be troublesome if he found the wrong one, but fortunately, it seems that he did not find the wrong one. So..."

As he spoke, Xiao Hei walked to the side of the sword cage, reached out his hand, grabbed QB, and threw it at Homura Akemi.

"I took this away, okay?"

"casual."

“Wait, wait!!”

Seeing this scene, Kaname Madoka screamed again.

"That child...what are you going to do to that child? It wants me to save it, and I..."

"Sister, please don't make subjective judgments. I'm not a bad person."

Looking at Kaname Madoka's tearful face, Xiao Hei rolled his eyes helplessly.

"Don't think that those who look pitiful are all good people. When criminals are chased by the police, they are even more embarrassed than this. Do you also think that criminals are good people... Then this... I'll take it?"

After saying this, Xiao Hei grabbed QB again and shook it towards Homura Akemi, who nodded slightly and said nothing.

However, at this moment, suddenly, a voice sounded.

"That won't do."

Along with the sound, several ribbons suddenly appeared on the ground. They jumped up as if they had life, and then tightly bound Xiao Hei and Akemi Homura. Then, a girl with golden curly hair came over. Although she had a smile on her face, her tone revealed uncontrollable anger.

"That child is my friend, could you please return him to me?"

“Wow, here comes another one. What a nuisance… ah!”

However, just when Xiao Hei was about to say something, QB, who was originally held in her arms, took this opportunity to jump up and escape from Xiao Hei's hands, then ran quickly towards Kaname Madoka and the blonde girl.

"ah--!"

Seeing the little white animal running towards her, Kaname Madoka hurriedly squatted down and stretched out her hands to pick it up.

However, at this moment...

"Wind, please turn into chains that bind me - WINDY!"

A howling gale suddenly rose from the ground, and the next moment it turned into a translucent barrier, wrapping QB in it. Then Sakura quickly rushed over from the other side of the passage and landed next to Xiaohei. At the same time, the "Wind Card" she controlled also pulled QB back steadily.

"Xiao Hei, are you okay?"

"I'm fine, just a little bit of an accident."

While joking with Sakura, Xiao Hei looked at the blonde girl in front of him again.

"Big sister, it seems like you don't intend to let us take QB away."

"Of course."

At this moment, the blonde girl also raised her right hand, and along with her movement, several muskets emerged from behind her.

"This child is my precious friend. I advise you to let him go. Otherwise, I will not be polite."

"Hey, um, I..."

"Xiaoying, I'll leave that QB to you!"

At this moment, Xiao Hei suddenly spoke, interrupting Xiao Ying's words, and then a few flashes of knife light flashed, and the next moment, the ribbon that originally bound Xiao Hei was torn and cut. Then Xiao Hei stretched out his hand, and soon, two short swords, one black and one white, appeared in Xiao Hei's hand.

"I'm here to meet this big sister. I heard that Nanoha had a fight with a magical girl from this world, and I'm a little itchy. Leave this curly-haired sister to me!"

"Ah... okay, I'll leave it to you then..."

Hearing this, Sakura nodded, and then used the wind card to restrain QB and walked to the side. Xiao Hei grinned and smiled at the blonde girl.

"Come on, big sister, let me see what you have to snatch someone from me!"

Having said that, Xiao Hei's eyes narrowed slightly, and then she whispered an inaudible spell.

"I'm the bone of my sword..."
