The originally abandoned underground tunnel turned into a battlefield in just a moment.

“Haa ...

The curly-haired girl suddenly waved her hand, and then dozens of muskets suddenly appeared in front of her, and then suddenly fired dazzling golden magic bullets towards Xiao Hei. However, facing the oncoming magic bullets, Xiao Hei was not afraid at all. She waved the black and white swords in her hands and instantly knocked the oncoming magic bullets away.

Then, Xiao Hei was seen holding the black and white swords in her hands and crossing them on her chest. At the same time, the low moaning in her mouth did not stop.

"Steel is my body, and fire is my blood."

“Swish!”

Along with the chanting, several hard black steel swords shot out from Xiao Hei, whistling towards the curly-haired girl. Seeing the long swords shot out by Xiao Hei, the curly-haired girl also jumped back in a hurry. At the same time, several intersecting muskets appeared in front of her again, smashing all the long swords into pieces.

“Bang, bang, bang!”

The black iron sword shattered, but among the debris and thick smoke, Xiao Hei's petite figure suddenly emerged. The black and white double blades in her hands drew arcs and slashed towards the curly-haired girl's neck!

However, the curly-haired girl obviously would not let Xiao Hei succeed so easily. As Xiao Hei stretched out her wrist, several ribbons appeared out of thin air and tightly wrapped around Xiao Hei's wrist, preventing her from taking any further action. Then the curly-haired girl grabbed the musket summoned from the void, aimed at Xiao Hei's forehead and pulled the trigger.

“Crack!”

But at the same time, a sharp blade fell from the sky and cut the musket in the curly-haired girl's hand into pieces along with the ribbon that bound Xiao Hei.

"I have created over a thousand blades."

Countless muskets bloomed like flowers with the curly-haired girl as the center, and the magic bullets shot out swept across the entire battlefield. Xiao Hei turned over and leaped up, with a black longbow in her hand. She held the black longbow tightly with her left hand and pulled the bowstring with her right hand. The moment she released the bowstring, a dense stream of light like meteors shot out, flying towards the curly-haired girl from all directions with different trajectories.

"Unknown to Death, Nor Known to Life."

“Bang, bang, bang!”

Facing the arrows shot at her, the curly-haired girl seemed to be able to fly in the air. She stepped on the wall and rushed forward at a speed unimaginable for ordinary people. One musket after another appeared in her hands as if they were free of charge. She clenched the musket, fired, threw it away, and then took out a new musket again, continuously aiming at the flying arrows, and Xiao Hei in the distance pulled the trigger.

Swords shattered in mid-air, cracks began to appear on the walls, and the ceiling shook and emitted dust from time to time. Huddled in the corner, Kaname Madoka was trembling, watching the battle in front of her anxiously, her mouth wide open but unable to utter a single word.

"What's going on? Why did the fight start?"

At this moment, Illya also quickly arrived and was shocked at the scene in front of her, while Sakura responded quickly.

"Sister Xiao Hei found QB and wanted to take it away, but the curly-haired sister said QB was her friend and refused to let Xiao Hei take it away, and then the two of them started fighting..."

"But this is too noisy. Luckily I saw the situation was not good and opened the barrier to repel people, otherwise... wait, Xiao Hei wouldn't..."

At the same time, Xiao Hei's chanting also reached its end.

"Yet, those hands will never hold anything. So as I pray, Unlimite Blade Works!"

At the moment the chanting ended, Xiao Hei happened to roll over and avoid the attack of the curly-haired girl. Then she landed steadily on the ground, looking at the curly-haired girl with a smug smile.

"Big sister, welcome to... my world!"

Before Xiao Hei finished her words, a howling wind mixed with smoke suddenly emerged from under her feet, then quickly expanded, covering everything around it.

“Ooooo…!”

Faced with the sandstorm, Homura Akemi, Madoka Kaname and the curly-haired girl all closed their eyes involuntarily. However, when the wind died down and they opened their eyes again, the scene before them completely stunned them.

The underground passage that had become dilapidated due to the battle between the two sides has disappeared, and in its place is a hill dyed red by the setting sun. It is densely packed with various weapons, and among the thick clouds, one can even see the constantly rotating gears.

"What on earth is this..."

Staring at the scene in front of her in astonishment, Kaname Madoka was completely speechless. Homura Akemi and the curly-haired girl also showed the same shocked expressions.

"This is……"

"Barrier? Could it be that... you are a witch?"

"Whatever you say, I want to see how you are going to defeat me now, big sister."

"Since you are a witch, I will not show mercy!"

Hearing Xiao Hei's answer, the curly-haired girl showed a cold expression, then she waved her hand suddenly, and summoned countless muskets from the sky again. For a moment, hundreds of magic bullets turned into a rainstorm and blasted towards Xiao Hei.

However……

"This makes absolutely no sense!"

Facing the barrage of bullets flying down from above, Xiao Hei giggled, then she suddenly raised her right hand.

"Rho Aias!"

A purple shield like a petal instantly unfolded in front of Xiao Hei, blocking the flying bullets. Then Xiao Hei looked at the curly-haired girl and swung his right hand.

Soon, the countless long swords stuck on the hill suddenly left the ground like soldiers who heard the general's order, whistling and stabbing at the enemy in front of them. Seeing the attack of countless sharp blades, the curly-haired girl gritted her teeth and once again summoned a musket array to block in front of her, trying to resist the almost infinite bombardment of sharp blades.

At the same time, the curly-haired girl raised her right hand behind her, and a huge musket that was taller than her and looked like a cannon appeared.

"This time, it's my turn to use my ultimate move!"

Seeing that the curly-haired girl seemed to be planning to use her trump card, Xiao Hei was unwilling to be left behind. She stepped back, then stretched out her hands to her sides and clasped them in the air.

"Trace on!"

Along with Xiao Hei's chanting, golden light gradually condensed and took shape beside her hand, transforming into a long sword emitting shining, holy heroic glory.

Xiao Hei held the sword with both hands and raised it high. The shining and brilliant hero light shot up into the sky.

At the same time, the huge musket in the curly-haired girl's hand also emitted a golden glow.

"Ex...calibur!"

"Tiro...Finale!"

The next moment, the golden torrent of light and the huge magic cannon bombardment collided heavily with each other!

The whole world was enveloped in dazzling light.
