When a huge light and explosion came from the mansion opposite, Illya's family was taken aback.

"What's going on!?" Illya looked at the house that had turned into a sea of fire in shock, and her heart tightened, "Oops, what's wrong with Miyu and Miss Luvia!?" ”

Thinking of this, Illya was immediately very anxious, and hurriedly rushed to the door of the house.

"Illya, don't run around!" When Serra hurriedly tried to stop it, Shirou Emiya on the side coughed lightly and looked solemnly at the big mansion that exploded.

"Serra, let's hurry up and call the police, we have to go to put out the fire first, and see if there are any injuries or something."

"Huh? Oh good! Serra quickly took out her phone and made a quick call.

Then Emiya Shirou also walked out the door: "I'll go and see how Illya is doing." ”

Then, when he walked out of the door and saw a pink figure flying in the air, he ignored it, but turned around and walked to the other side, taking out his mobile phone.

After dialing the phone number that had just been added, Emiya Shirou whispered, "Xana, are you rushing this way?" ”

"Of course!" A girl's dissatisfied voice came from the phone, "With such a big explosion and magic fluctuations, there must be a heroic spirit fighting on your side, if something happens to you, won't I be able to get the Holy Grail!?" ”

"I don't have a problem here, you don't have to come over, otherwise if your identity is exposed, it will only add to the chaos."

"No Road Race!" Far away, a girl with flaming wings landed on top of a building, looking out at the light of the night sky, "Don't blame me for your death, master!" ”

Xia Na hung up the phone angrily, and then just about to turn around and fly away, but suddenly her steps froze, and her eyes fell on a figure at the end of the roof.

"When...... Appearing here? Xana's expression sank.

The gemstone necklace on her body shone slightly, and then a deep voice came out: "Since you went out just now, I have always had a feeling of being followed, but the other party is too well hidden, so I am not sure." ”

"Arastre, do you mean they found out about us early in the morning? How is it possible, I have already used the power of existence to replace myself with the existence of ordinary people! Xana asked incomprehensibly.

"It's hard to spot in theory...... "The necklace on Xana's chest replied in the same incomprehensible tone.

"Caster Xana, using the so-called 'power of existence' to replace herself with the existence of Sakurai Xue, a student of the High School of the Honkaihara Academy, so it is ununusual to integrate into the High Department of the Honkara Academy, and even other Heroic Spirits and magicians can't detect that you are actually a Heroic Spirit's existence." The young man in a black trench coat on the opposite side walked slowly and spoke with a faint smile.

"Why...... Would you know so well? Xia Na's red eyes, like burning flames, became more and more cold, and then she pulled out a long sword from the night hat that spread out behind her, and pointed at the black-haired boy in front of him.

"I'm sorry......" the dark-haired boy shook his head slightly, "I don't have much time for small talk, I have to beat you before your master arrives." ”

Then he leaned forward slightly, and as soon as he stepped on the ground, he swept a long distance, and the moment the five fingers of his right hand were clenched, a black long sword condensed in the palm of his hand, and slashed at Xia Na head-on.

"Be careful!" Arastel let out a low snort, and Xana took a step forward in response, and the sword in her hand swung diagonally at the same time, colliding with the long sword of the black-haired boy.

"Sword, Saber?" Shana held the hilt of her sword against the black-haired boy's sword with both hands, "So, the other party's master is also nearby?" ”

"That's right, you need to be more careful. If the opponent's master really has such a strong strength as Wei Gongjun, it will be a little bad. Arastelle's tone was solemn.

Suddenly, the black-clothed young man flicked his long sword, forcing Xia Na to slide back two steps, his heel clinging to the edge of the top floor, and behind him was a bustling street with a drop of dozens of meters.

"Danger!" At this time, Arastel suddenly shouted, only to see that the young man in black actually swept an oblique arc and leaned over and rushed directly into Xana's attack range.

And the black long sword in his hand also slid low across the ground, slashing towards Xia Na's waist with a cold glow.

Xia Na had just been shocked back, and she didn't expect that the other party would attack at such a tricky angle in an instant, so she only had time to hold the hilt with her backhand, and stood up to block the front of the black long sword again.

Although she would definitely be shocked out of the building by the other party, it was not a big problem for her, who had already spread her flame wings and could fly in the air.

However, she did not expect that the "danger" in Arastel's mouth was much more than that.

The moment the black sword collided with Xana's sword, sparks flew everywhere, but there was no such thing as the great force that Xana had imagined.

But at the moment when the two came into contact, the black-clothed young man actually took this opportunity to twist his toes, driving his entire body to rotate, and the black long sword quickly swung through an arc and ran towards Xia Na's other waist.

As early as the beginning, Xia Na was preparing to take the first slash of the black-clothed young man, who would have thought that the other party would actually retract his power so freely, just by symbolically touching the blade, he could quickly change the attack and slash out the second blow.

This slash can't be stopped by Xana's sword alone.

Xia Na whispered a few syllables, and when the long sword was less than a palm away from Xia Na's body, the black-clothed young man kicked the ground fiercely, and jumped out of a large distance in an instant.

And where he was just now, it was already engulfed by a large cloud of blazing flames.

Then the flame burst into flames, condensing a huge flame giant hand, blocking between Xana and the boy in black.

"What's going on with this guy, as if he can see what trick I'm going to use?!" Xia Na gritted her teeth and glared angrily at the black-clothed young man who looked relaxed not far away, and couldn't help but whisper.

"Not only that, judging from the appearance alone, the other party's age is not much different from yours, but in terms of swordsmanship, it is definitely much stronger than you who have been trained in the Heavenly Dao Palace since childhood." The necklace that Arastel had deposited shone slightly, and his voice could be heard to be extremely solemn, "This is definitely a very difficult enemy. ”

"Then, there is no other strategy." Xia Na took a deep breath and the flame wings whistled and flapped, and suddenly her whole person flew directly into the air, looking down at the black-clothed boy below, and once again condensed four flame giant hands, and pounced on the black-clothed young man standing quietly on the roof of the building.

"If the other party doesn't have the ability to fly, use the freedom method to decide the victory!" As soon as Xia Na's words fell, she was stunned to see that a faint light appeared behind the black-clothed young man, and then there were more slender wings like fairies, and his body was suddenly blurred, and he quickly dodged the encirclement of the flame giant hand left and right, and chased to Xia Na's side in the air in an instant.

The black long sword in his hand swept out heavily.
