My fiancée Yukino

Hiratsuka Shizuka smiled and said, "That's really nice. If there's a chance in the future, let me get to know you. That's all for now. I won't bother you any longer. Good night, you have to go to school tomorrow."

"Okay, goodnight, Hiratsuka-sensei. See you at school tomorrow."

After hanging up the phone, Luo Bai looked at Rin Tohsaka, who had come to his side.

"Why are you here? Weren't you playing cards just now?"

Shaking her head, Rin stretched lazily and said, "My luck at cards was bad today. I lost six hands in a row, so I had to ask Yang Nai to replace me. What about you? Have you finished explaining to the teacher?"

"Yes, Ms. Hiratsuka is a qualified homeroom teacher. Although she knew I must have something to do to ask for leave, she still called to find out. It's not a big problem."

As he spoke, he picked up a cup from the coffee table, took a sip, and comfortably squinted his eyes.

"The Misaka Sisters issue has been resolved, but Academy City is a different story. There will definitely be more big things to come. He backed down when he met Aleister this time, but he's probably already planning to include me in his future schemes."

After hearing this, Rin asked curiously, "So, you're not planning to do anything to that Aleister?"

"I'm not interested in the specifics of what's going on in that world, but because of the Misaka Sisters, we can't ignore the safety of Misaka Mikoto and Shokuhou Misaki. Barring any unforeseen circumstances, when a major incident occurs, Aleister will definitely use some means to get Misaka Mikoto and the others to contact me. Of course, this isn't necessarily a bad thing; we've trained quite a few people here, and they need some real-world experience. Our world won't face such a major crisis for now, so we'll just have to go to other worlds to practice. Well, it's mutually beneficial."

The Guardians organization has a diverse range of talents, including combat experts, scientific researchers, and more.

Among the combatants, there are those skilled in melee combat, ranged combat, magic, and even wizards skilled in curses.

Although there are many combatants, there aren't that many villainous enemies in the world for the team members to practice on. Therefore, a large portion of the team members lack practical combat experience and can only increase their experience through daily simulated battles.

However, there is still a significant gap between simulated warfare and actual combat.

Now that a world called "A Certain Magical Index" has appeared, Luo Bai can't help but think that there are a lot of people in this world who like to cause trouble.

It's hard to say about the level of demon gods, but those troublesome mages on the magic side are excellent experience points.

Looking at Rin, Luo Bai smiled and said, "Want to go when there are battles later? A large part of the battles there are against the magic side, you should be interested."

"Sigh...someone from the magic side, a magician?"

If it's about magicians, Rin is indeed quite interested. She's been exposed to a lot of magic and spells she's never encountered before, and her strength has been steadily improving. She definitely needs to gain more combat experience.

After a brief moment of thought, Rin nodded vigorously: "Then, just call me when you need me, I'll do my best!"

At 10 p.m., although they had received treatment, the Misaka Sisters were not yet healthy enough to stay up all night. After playing around for a while, they were also a little tired.

So Luo Bai made the decision immediately: get some rest early tonight.

Although Last Order chose the last available room here as her bedroom, Ilya still dragged her to her place today. The two planned to sleep together tonight so they could chat.

Late at night, after Yukino and Utaha had fallen asleep, Luo Bai went to the bathroom to wash his face quickly, and then went downstairs to get some water.

I went to the kitchen to get a bottle of mineral water, and as soon as I came out, I saw the portal to the living room open, and the witch Elena, whom I hadn't seen for a long time, had arrived.

"Irena? Why are you back at this time?"

Upon seeing Luo Bai, Elena paused for a moment, glanced around, and whispered, "I... I didn't expect to choose to come here..."

Seeing Elena's expression, Luo Bai frowned and walked over to ask, "Did something happen?"

The moment she finished asking the question, Elena hugged Luo Bai and nestled in his arms.

Sensing the self-blame and unease emanating from Elena, Luo Bai didn't ask any further questions and gently hugged her.

Half an hour later, Luo Bai listened to Elena finish recounting her past experiences and sighed with emotion.

"Traveling through time? That's forbidden."

Volume 1: Chapter 716 Irena's Return and Her Encounters (2/2)

A serial killer, a time traveler—Irena has indeed experienced some truly outrageous things these past few days.

A sorcerer she knew wanted to travel through time to stop and save her friend who had become a serial killer, and Elena went along with him.

In the end, it was discovered that her friend had been acting strangely from the beginning, and that she had killed her own parents, not that they were killed by criminals.

After the battle, the witch named Estelle, who desperately converted her memories into magic, ultimately killed her friend for the second time.

Upon returning to the world ten years in the future, Estelle unsurprisingly lost all memories of her friend and was also severely injured. Even though Elena treated her, it wouldn't last long.

After that, a dazed Elena left the witch Estelle's residence and returned here.

Stroking Elena's silver-white hair, Luo Bai said softly, "It must be very painful to face something like this."

With tears in her eyes, Elena said, "I'm still not mature enough. Even though I've been through all sorts of battles, I still couldn't stay calm in the face of something like this, and I didn't even know what to do. I went back to the past, but I couldn't change anything; instead, I made her go through it all again. So, is the past really unchangeable?"

Luo Bai paused for a moment before saying, "The time-travel magic that the witch developed does indeed have a certain possibility of changing the past, but for what she wants to change, a ten-year span is not enough. And if she wants to go back further, neither magic power nor blood will be enough to support this magic. Time cannot be easily toyed with; it will come at a huge price. If she were to do it at the cost of her life, it could very well lead to an even greater tragedy, just like what you experienced this time."

"..."

Irene did not answer, letting Luo Bai wipe her tears with a tissue.

Seeing that Elena's emotions were gradually stabilizing, Luo Bai felt somewhat relieved.

However, turning back time and changing the past...

Luo Bai had seen many books on time-related magic in the base's library, and he had also studied some of them himself.

However, with his current strength, he has not yet been able to unleash the kind of magic that allows him to travel through time, nor can he prevent any unexpected consequences that might arise from it.

I traveled through time once before in the Type-Moon world, and it was only because of the interference of the Counter Force that I succeeded.

However, when you switch to your own world, because this world has already connected with many other worlds, the influence of time will become increasingly significant, and the difficulty of time travel will increase exponentially.

Luo Bai originally wanted to study it further and then change Ying's past, but now it seems that he can't do it in the short term.

Elena's situation is a perfect example. Even though it's a world where they've developed magic to reverse time and repair items, traveling through time still causes such serious consequences.

Playing with time is indeed an extremely dangerous thing. It comes at a great cost and is very unstable. Any small action can cause irreversible damage to the person, and then the past cannot be changed.

It's so painful, it's truly painful.

Looking at Elena, Luo Bai comforted her, "This was something that couldn't be helped. It was the best you could do. Elena, don't blame yourself."

Leaning against Luo Bai's chest, Elena nodded: "I know, but when I think back to that scene, I still can't help but feel sad."

"That's how travel is. Along the way, you'll see happy things and you'll also encounter things that make you sad. Even if you know it, that's what you have to face on your journey. If you're feeling down, just rest here for a while and adjust your state. I've finished dealing with things here for the time being, so I won't be traveling around. Whether you want to go out and have fun or stay at home and rest, that's fine too."

"Okay, then I'll rest here for a while. I also need to organize my travelogue."

Nodding, Elena rubbed her stomach and looked at Luo Bai, saying, "I'm hungry, is there anything to eat?"

Luo Bai smiled and replied, "Of course, and we also support ordering food."

Irene wasn't greedy and just ordered a bowl of noodles.

After Luo Bai finished cooking for her, Elena pulled Luo Bai to sit down in the living room again, and under the cover of night, she asked him about his experiences during this period.

Seeing that Elena wasn't planning on sleeping, Luo Bai simply stayed with her and told her about his previous experience going to the Singularity and how he went to the A Certain Magical Index world yesterday to rescue Misaka Mikoto.

As the story unfolded, time passed slowly, interspersed with Elena recounting her travels, such as visiting her teacher at the Royal Magic Academy, passing through a wine-making village, and being asked to help make wine as a grape-stomping girl.

As Elena finally drifted off to sleep that night, her emotions calmed down considerably.

Seeing that the sky outside was already bright, Luo Bai gently picked up the girl in his arms and carried her upstairs to Elena's bedroom, which had been empty for some time.

"Only I can go a night without sleep without any problems; other people really wouldn't be able to handle it."

After settling Elena in, Luo Bai came out of the room and happened to meet Yukino, who was rubbing her eyes as she came out of the bedroom.

Upon seeing the doorway where Luo Bai was, Yukino paused for a moment before realizing, "Irena's back?"

Luo Bai nodded slightly: "We've been through a lot, and I spent the whole night talking with her before I finally fell asleep. It's not even seven o'clock yet, why don't you get some more sleep?"

Yukino glanced at the bedroom and said, "I was very uncomfortable sleeping with Utaha holding me up. It was about time, so I decided to get up."

Then, the two went to wash up together, and Luo Bai briefly recounted what Elena had experienced.

I told Yukino while I was washing up.

After wiping her face, Yukino put down the towel and sighed, "I never expected something like this to happen. I originally thought that with the strength of the witch Elaina, she would at most encounter some danger, but she could still resolve it. But this time, she has encountered such an unsolvable situation."

"That's how time works. Even if a powerful global will actively intervenes, some unpredictable changes will occur. If human effort tries to change the past, it has to face the challenges that time presents. If it can't be resolved, then one can only bear the consequences and the pain."

Looking at himself and Yukino in the mirror, Luo Bai said softly, "For example, when facing Goetia before, if my future self hadn't developed the ability to travel through time and successfully transferred the power to my present self, we would have suffered heavy losses in the battle against Goetia. Mash and Gudako would definitely not have been able to live a happy, ordinary life here, Roman would most likely have perished together with Goetia, and Chaldea would have suffered more than half its losses."

Then, he saw Yukino take his hand.

With a smile, Yukino looked at Luo Bai and said, "Believe in yourself, you can do it. But now, it's time to make breakfast. I'll also help Elaina cheer up."

"Okay, let's go downstairs then."

Volume 1: Chapter 717 A Harem of Over Ten Thousand? (1/2)

At the breakfast table, Medea nodded in realization after hearing about what happened last night: "So that's how it is. I was wondering why I sensed someone coming around in the middle of the night. After I found you coming down, I didn't come out. So it was Elena. Time travel, the magician in that world, she really had a lot of guts, daring to do something like that."

In Medea's time, there were also divine magicians who wanted to study the mysteries of time, but they all failed.

Medea herself was well aware of the danger involved, so she had no such thoughts whatsoever.

Rin also glanced curiously in the direction of the stairs.

"Is it okay to let her fall asleep on her own?"

Luo Bai shook his head and said, "It's alright, she just went to sleep this morning. She's quite familiar with the area, so there's no need to worry about her. Medea, Medusa, if she wakes up later, please help look after her as well."

"Leave it to us with confidence," Medea said with a smile. "I've long wanted to meet this genius magician from another world."

After breakfast, Luo Bai and the others went to school, while Shinobu Kocho, along with her sisters and three Misaka Sisters, went to the base for treatment.

At 11 a.m., the bedroom door opened, and Elena walked out in a daze.

"Ah, I've had a good sleep. I didn't expect to sleep until noon. According to the note Luo Bai left, he has already gone to school, but there are other people at home. I also noticed a special magical fluctuation. Although it wasn't very noticeable, it was definitely very strong."

After a quick wash and change, Elena went downstairs and saw Medusa and Medea reading in the living room. It was the first time she had ever seen either of them.

"You're awake? We were just discussing whether we should come up and knock on the door, since it's almost lunchtime."

Setting down her book, Medea looked at Elaina and said with a smile, "Hello, Miss Elaina, I am Medea, a Heroic Spirit and a magician."

Medusa said, "I am Medusa, and also a Heroic Spirit."

"Oh! Heroic Spirits, I heard Luo Bai mention you last night. Hello, I am Elena, and my witch title is the Gray Witch."

After sitting down on the sofa, Elena looked at Medea and said, "Your magical energy fluctuations are quite unique!"

Medea chuckled, "Of course, after all, we come from different worlds, and our power systems are different too. I've also learned about some of the magic in your world from Luo Jun, and quite a few of them are quite interesting. We can have a good exchange later. But before that, let's think about what to have for lunch this afternoon, since neither Medusa nor I are very good at cooking. We also brought our two maids, Ilya, to the base."

Medusa said, "Why don't we go out to eat? We have money anyway, and I'd like to find some new novels I haven't read yet."

Then, the two looked at Elena.

Elena nodded happily: "Okay, let's go out then. It's been a while since I've been here!"

At school, after the morning classes, Luo Bai was having lunch in the club room when she received a text message from Elena with a photo of her having lunch with Medea and Medusa outside.

It seems that she has adjusted her emotions quite well.

Because he was going to visit the Misaka Sisters at the base after school in the afternoon, Luo Bai sent a message to Elena, telling her that if she was free, she could also go to the base later and they could all meet there.

Elena was also curious about the Misaka Sisters' situation, so she decided to go for a walk outside with Medusa and Medea in the afternoon before heading to the base.

At four o'clock in the afternoon, Luo Bai brought Yukino and the others to the base, while Xiao Ai went to STARRY to continue working on the new song with Hongxia and the others.

The treatment was very effective. Even the Misaka Sisters, who had been in the incubation chamber, could now move freely and had fully learned cognition and language. They were curiously looking around to understand and learn everything they wanted to know.

As soon as Luo Bai arrived, he was instantly surrounded by the Misaka Sisters.

"Ah, it's my older brother! This is the first time Misaka has met my older brother. I'm so happy."

"Big brother, Misaka's ability has been upgraded from Lv2 to Lv3, all thanks to you, big brother."

"My brother is so handsome. I wonder if I can stay and have dinner with Misaka." Misaka was excitedly looking forward to it.

Watching the Misaka Sisters chatting away, their voices lively but not noisy, Luo Bai smiled.

"Looks like you had a good day here. Come on, let's go inside. I still need to look at your treatment reports. By the way, where's the Last Work?"

"Misaka Misaka is here!"

When the voice of Last Order came, Luo Bai realized that Last Order was actually being held back outside by the Misaka Sisters.

After all, this child's figure is too petite, and she simply cannot squeeze into the circle of the other Misaka Sisters, even though she is the command tower of the Misaka Sisters.

Beside Last Order are Misaka 9982 and Dolly.

After Last Order squeezed through, Luo Bai smiled and picked her up, then walked towards the medical department surrounded by the other Misaka Sisters.
