"What, what is this?!"

Saten Ruiko could feel the power of the wind contained in the blade. The wind seemed to resonate with her, filled with a strange flow... Oh, is this the perfect model that Mr. Fang Zheng mentioned? Not only that, this blade is so big, but it looks as light as a feather, not heavy at all... Wait!

At this moment, Riri Saotome was suddenly surprised to find that the blue-haired girl who was beside her was gone!

"Hey? Hey? Where's the kid?"

【careful】

However, just as Riri Saten was looking around, the voice of the blue-haired girl suddenly emerged in her mind, and then Riri Saten saw the polluted beast in front of her rushing towards her immediately!

"Woooooa ...

[Concentrate your mind, gather your strength, and chop it down]

“Ah… yes!”

Although she didn't know what was going on, Leizi still followed the voice in her head, raised the wind sword in her hand high, and slashed at the polluted beast in front of her. However, a scene that Leizi could not imagine happened just like that.

"call--!!"

As Lei Zi swung the sword, the next moment a wind blade as thick as her arm instantly burst out from the sword and instantly split the polluted beast in front of her into two. Then Lei Zi saw that the moment the wind blade penetrated into the body of the polluted beast, it suddenly exploded and turned into a raging gale, directly tearing the polluted beast in front of her into pieces from the inside!

"Woooooa ...

Seeing this, Lei Zi was also shocked. She didn't expect that this sword was so powerful!

You have to know that before, with the help of Fang Zheng's artifact, Ruizi's ability level was only about Lv3, and the wind blade she released was only the size of a thumb, and this was the result of Ruizi's full strength. But just now, Ruizi felt that she only exerted a little force, but it produced a kind of effect similar to a little effort to achieve a great result... She didn't understand this word, but if Ruizi used the words she knew, it would be that she felt that she used her Lv2 ability to release a Lv4 level!

This is horrible!!

[Be careful, it comes again]

But now, Ruiko Saten had no time to be distracted by this. At this moment, the voice in her head sounded again, so Ruiko Saten hurriedly concentrated her mind and looked forward again. At this moment, the polluted beasts from several other places had also rushed over and surrounded Ruiko Saten.

"Let's break out first!"

Riri Saotome was no longer an ordinary girl. After all, she had seen so many strange things with Fang Zheng. Now that she had come to her senses, she could probably guess that the sword that had inexplicably appeared in her hand might be related to the blue-haired girl just now. So she immediately gathered her spirits, swept the sword directly, and ran towards the passage where she had just defeated the pollution beast.

This is the difference between Saten Ruiko and Misaka Mikoto. If it were Misaka Mikoto, she would not leave until she killed these polluted beasts. But Saten Ruiko is different. After all, she was originally a powerless person, and she does not have the domineering power of Level 5 like Misaka Mikoto. Therefore, she is more sober when facing the battle.

Riri Saotome also has her own judgment on when to fight and when to run. No one knows how many polluted beasts there are here, and no one knows how long this sword can last. Instead of fighting to the death here, it is better to escape to a safe place quickly. There is such a big noise here, Mr. Fang Zheng must have discovered it a long time ago. As long as she can hold on until Mr. Fang Zheng and others come to rescue her, there will be no problem!

Thinking of this, Ruiko Saten immediately turned around and rushed in the direction of the polluted beast that she had just torn apart. Although this passage was filled with blood and stench because of the polluted beast that had been torn apart, Ruiko Saten didn't care about this at the moment. She gritted her teeth and used the Gale to speed up and fly forward.

Behind Saten Ruiko, the pollution beasts were also chasing closely. Their bodies were not as big as the ones Fang Zheng had encountered before, so they were much faster. If Saten Ruiko had not listened to Fang Zheng's instructions and used the wind to speed up, she would have been caught up by the pollution beasts by now.

However, even so, the good luck soon came to an end. Soon, Riri Saotome saw that the road in front of her was cut off again, leaving only a section of wreckage, and below was a bottomless abyss.

But Lei Zi had no other choice at the moment.

“Drink…!!”

Looking at the broken iron bridge in front of her, Lei Zi gritted her teeth and leaped out suddenly. Then she raised the long sword in her hand and pointed it downwards. The next moment, a roaring airflow suddenly spurted out, carrying Lei Zi upwards! The pollution beasts obviously did not have the ability to fly. They rushed over and could not brake in time, and fell directly from the edge of the iron bridge.

“Hahaha, it worked!”

Seeing this, Lei Zi was relieved. She had thought about using wind power to fly a long time ago, but her ability level was too low, so she couldn't do it at all. Lei Zi just tried it as a last resort. After all, with the help of this sword, she was able to exert Lv4 power, so she should be able to fly!

The fact was just as Ruizi thought, she actually flew!

Next we need to find a place to land...

While thinking of this, Lei Zi adjusted the wind speed while looking around. Soon, Lei Zi locked onto a platform above her head not far away, and increased the wind speed again to fly towards that direction.

Just a little bit more... Just a little bit more...

However, just when Ruizi was an arm's length away from the platform, suddenly, the voice of the blue-haired girl appeared in Ruizi's ears again.

[No, I can’t hold on any longer]

"Hey? Wait, don't..."

Hearing this, Lei Zi's face suddenly changed. However, before she could finish her words, the wind blade wrapped around Lei Zi's right hand disappeared instantly. At the same time, the blue-haired girl appeared beside Lei Zi again. Without the support of their power, the two of them fell into the bottomless abyss again.

“Wow——!!”

At this moment, Lei Zi also screamed loudly, but then her eyes went dark and her butt fell heavily to the ground. At the same time, Shirai Kuroko's voice came from beside her.

"Really? What on earth are you doing?"

"Shirai-san!"

Hearing Shirai Kuroko's voice, Saten Ruiko finally breathed a sigh of relief. She opened her eyes and saw Shirai Kuroko with his hands on his hips, staring at her helplessly, while the blue-haired girl was standing beside Shirai Kuroko, looking around in confusion, it was obvious that she didn't know what was going on.

"I just heard some noise downstairs, and Mr. Fang Zheng said that something might have happened to you, so my sister and I came here in a hurry to look for you... What on earth are you doing?"

"Oh no, Shirai-san!"

Having said that, Riri Saotome reacted hastily.

"There are pollution beasts down there, lots of them!"

"Pollution beast?"

When Shirai Kuroko heard what Saten Ruiko said, her expression changed.

"Let's get out of here first, but then again..."

Having said that, Shirai Kuroko looked at the blue-haired girl beside him in confusion.

"Who is this girl with you?"

"It's a long story, let's go back to Mr. Fang Zheng first."

Riri Saotome is not willing to waste time here right now. Although those polluted beasts seem unable to fly, who knows if there are any that can fly?

"I see."

As he spoke, Shirai Kuroko turned his head and looked to the side.

"Please inform Mr. Fang Zheng that the person has been found."

As Shirai Kuroko was speaking, Saten Ruiko only then noticed a pink petal quietly falling from the sky and then disappeared without a trace.

"What's this?"

"This seems to be a power called 'Mind Power' that Miss Fili possesses. She just used this power to find you... Never mind, let's talk about the rest when we get back."

With the help of Shirai Kuroko, the journey back to the core control room was very smooth. After all, spatial movement completely ignored all kinds of obstacles and was perfect for escaping. Saten Ruiko was already used to it, but the blue-haired girl stared at Shirai Kuroko in surprise all the way, as if she wanted to figure out how he did it.

When Shirai Kuroko brought the two back, the others had already gathered.

"You are really good..."

Silently looking at the blue-haired girl beside Ruiko, and listening to Ruiko's smiling story about how she found the blue-haired girl, Shirai Kuroko and Misaka Mikoto both looked as if they were listening to a mystery, while Fang Zheng was speechless.

Of course he knew this girl. If Fang Zheng remembered correctly, she was the Holy War Angel, Lovely Mezalanth, one of the Seven Brilliant Treasure Trees.

The Holy War Angels have the ability to transform into weapons and fight together with humans through synchronization contracts with humans. Fang Zheng has seen this in animations before, but at that time he only had a slightly deeper impression of the heroine, and he doesn't remember the story itself very clearly.

If Fang Zheng remembered correctly, Lei's attribute was wind, which was quite compatible with Saten Ruiko's air flow control...

"This girl can become a weapon?"

After hearing what Ruizi said, Misaka Mikoto and Shirai Kuroko both looked incredulous.

"Is this really true?"

"What's so strange about this? I have the same problem."

At this moment, Fang Zheng also interrupted with a smile, immediately attracting the attention of others.

"Really? Mr. Fang Zheng? How come I've never seen you use any weapons?"

“Because there’s no need.”

Facing Riri Saotome's words, Fang Zheng shrugged his shoulders and told the truth. Then he stretched out his hand, and soon, two magic marks appeared on the back of Fang Zheng's hand.

"Come out, Restia, Esther."

Following Fang Zheng's call, a pitch-black broadsword and a silver-white dagger appeared out of thin air in front of the girls, and then transformed into a purple-haired girl with dark purple hair and a Gothic dress, and a silver-haired girl in a pure white dress. The two girls slowly landed on the ground and saluted everyone.

"Nice to meet you. I am the dark elf, the magic sword that pierces through reality - Restia."

"The Holy Sword of Demon Slayer - Esther."

“Wow…!”

Seeing this, Misaka Mikoto, Shirai Kuroko, Saten Ryoko, and Fili all widened their eyes in surprise, looking at the scene in disbelief, and Lei was also looking at the two girls in front of her in surprise, not knowing what to say for a moment.

"That's amazing, Mr. Fang Zheng, so amazing, are they the same as Lei?"

After introducing herself, Lei Zi now knew Lei's name, and she excitedly came to the two sword elves, staring at them curiously.

"Almost the same, but not quite the same. They are the spirits of swords, and Lei can only transform into swords."

Having said that, Fang Zheng looked at Lei and nodded, while Restia and Esther smiled at Lei, without any of the hostility they had towards Frostmourne before - well, probably because the person they had contracted was not themselves.

If Lei chose to make a contract with herself, I'm afraid Restia and Esther would be jealous by now.

Having said that, Ruizi's luck is really good.

While thinking, Fang Zheng looked at Lei Zi who was holding Lei's hand and chatting with Restia curiously, and couldn't help but chuckle.

This scene reminded Fang Zheng of a statement he made when he watched an anime a long time ago, that is, Misaka Mikoto is not the protagonist of A Certain Scientific Railgun at all, the real protagonist is Saten Ruiko. It's the same reason why INDEX is not the protagonist of Index of Forbidden Books...

The other party also listed several reasons to prove that in "A Certain Scientific Railgun", Misaka Mikoto was actually only a central character, not the protagonist.

First of all, in Japanese ACG, most of the protagonists are ordinary, good at housework, gentle and considerate - Ruiko Saten just meets all the conditions. She is a level 0 incompetent person, good at cooking, energetic and cheerful, and also gentle and delicate.

Secondly, all the protagonists have the physique to trigger events - facts have proved that almost all the events in "A Certain Scientific Railgun" started with Ruiko as the catalyst. The Fantasy Hand was first told by Ruiko as an urban legend, the chaotic opening incident was also where Ruiko saved everyone from the fire and water, the beginning of the SISTERS incident, it was also Ruiko who first witnessed her sister and told it to Misaka Mikoto, and in the Febre incident, Febre was also sticking to Ruiko.

In the end, the protagonist is able to inadvertently turn his enemy into a friend and bring him into his harem - in this respect, Saten Ruiko's aura is even stronger than Kamijou Touma's.

In the novel, four people went to the Academy City together and encountered a crisis. The enemies on the magic side tried to control a certain weapon to launch an indiscriminate attack on the Academy City. However, the magician who was in charge of controlling the weapon immediately and decisively chose to abandon the magic society's decades-long plan and dismantle its weapon after seeing Ruiko. She had only met Ruiko once before. Ruiko treated her to a meal and changed her into a swimsuit. That was the extent of their relationship.

In the comics, when Ruiko was abducted by the Anbu because of the poker incident, it was Frenda who stepped forward to rescue her, even at the risk of getting hurt herself - but before that, the only interaction between the two was when Ruiko made a meal of canned mackerel for Frenda.

Kamijou Touma needed the friendship punch to build a harem, but as long as Saten Ruiko meets someone, treats them to a meal, and chats with them, the other person will be willing to risk his life for her.

Kamijou Touma really can't compare to this aura...

Even Misaka Mikoto can't compare.

Of course, these events are unlikely to happen again because of Fang Zheng's actions. The external magic world has become a mess because of the decline of the Vatican, and the Anbu in Academy City have all left. However, some things cannot be changed. For example, Frenda has become good friends with Ruiko and often goes to Ruiko's house to eat mackerel dinners, and INDEX is also sticking to Ruiko Saten and is unwilling to leave...

So it doesn’t seem to be anything strange that Riri Saotome picked up a Seven-Colored Treasure Tree.

But... for Fang Zheng, this is certainly not a bad thing.
