Lei was pulled over by Esther and Restia to chat. After all, as sword elves, the two had never seen a race like the Holy War Angels, and were quite curious about Lei. Lei had also never seen a sword elf, so the two sides chatted very lively with each other.

But Ruiko was miserable. Ever since she came back, she was pulled aside by Shirai Kuroko and lectured. She was told not to act rashly, that she should notify them first if anything happened, and that she should be careful in everything... Ruiko looked very bitter after hearing this, and had no choice but to beg for mercy from Fang Zheng with her hands clasped together.

"Alright, alright, this time it's my fault too. Next time I'll give each of you a personal terminal. Ruizi was just unlucky."

Seeing Lei Zi's pleading eyes, Fang Zheng also came out to smooth things over. He was not wrong. In fact, if Lei Zi had a personal terminal at that time, she would definitely contact others immediately. Unfortunately, Lei Zi really had no means of communication at that time. However, if it weren't for this incident, Lei Zi probably wouldn't have shared the same bond with her. So whether Lei Zi's luck was good or bad...

That would definitely be good.

"Thank you, Mr. Fang Zheng!"

Lei Zi, who was rescued by Fang Zheng at this moment, hurriedly thanked him and then asked curiously.

"So, Mr. Fang Zheng, what's going on with your investigation? Are there any results?"

"I'm almost getting the idea."

Fang Zheng shook his personal terminal. After scanning the abandoned core of the mobile city, Fang Zheng indeed obtained another set of coordinate manufacturing information. However, because the core itself was dead, most of this information became garbled, so Fang Zheng even had to use his divine power to activate it before successfully decoding it. But anyway, although it was a bit troublesome in the middle, the information was still obtained.

"Then we should go too...where's she?"

"Why?"

Seeing Fang Zheng glance at Lei, Lei Zi suddenly became anxious.

"Mr. Fang Zheng, are you planning to leave her here alone?"

"Of course not. I mean, is there anything else she'll do after she wakes up? Or will she stay with you?"

Fang Zheng remembered that the animation seemed to say that Lei was going somewhere, but that world was obviously not the same as this one, so he was not sure about Lei's current situation. Lei Zi seemed to have just come to her senses at this moment, and hurriedly ran to Lei's side, asking in a low voice. After a long while, Lei Zi raised her head and looked at Fang Zheng in embarrassment.

"Um...Mr. Fang Zheng?"

"Um?"

However, before Lei Zi could say anything, Lei came in front of Fang Zheng, raised her head and stared at him.

"I want to go to the Eddielu Courtyard."

"Eddielu Courtyard?"

When they heard the name, everyone looked at each other, and Lei nodded.

"That peaceful place, above the sky, among the clouds, invisible, where existence is nothing and nothing is existence, magnificent and carefree, creating new wealth and laying a new foundation..."

"Well……"

Faced with Lei's description, everyone looked confused. Fang Zheng frowned and looked at Feili.

"Have you ever heard of the Eddielu Courtyard?"

"No, I have never heard of such a mobile city."

"But the city Lei mentioned, judging by the description, should be in the sky! We should be able to help Lei find that place!"

"That's not a problem, the problem is..."

Having said that, Fang Zheng shrugged his shoulders.

"None of us knows where the place called Edielu Court is?"

"Well……"

This time, Lei Zi was speechless. Indeed, even Fili, who was born and raised in the local area, had never heard of such a place, let alone outsiders like them.

"I……"

However, at this moment, Lei spoke.

"I can feel it...it's calling me..."

As she spoke, Lei looked towards the north.

"Well, it seems we still have a human radar."

Fang Zheng shrugged his shoulders, then he stared at Lei seriously.

"Well, Lei...can I call you that? I want to tell you something."

"……What's up?"

"First of all, you have to know that a very long time has passed since the era you were in. A hundred years, two hundred years, or even longer. Do you understand? You see, now no one knows what the Holy War Angels are, and no one knows who you are."

At this point, Fang Zheng pointed at Feili, and everyone realized that although Lei's behavior seemed to be no different from that of ordinary people, if you think about it carefully, Lei was found by Leizi in the warehouse of this city. And according to Feili, this city was conquered by the contaminated beasts almost a hundred years ago.

In other words, although this girl looks about the same age as them, she is at least over a hundred years old!

"So, the Edilu Courtyard you are looking for is likely to have been destroyed just like this city. Do you understand?"

“…”

Hearing this, Lei hesitated for a moment and nodded.

"Even so, you still want to go?"

"Yes...I'm going to go no matter what."

"That's fine."

Fang Zheng didn't take it seriously. In his opinion, since this was the world, then that courtyard must have the core records he was looking for.

"Well, let's go now. You can sense it from time to time. If there are any deviations, you can just tell me directly. Do you understand?"

"OK."

"Okay, let's go back then, we're done here."

After getting Lei's confirmation, Fang Zheng didn't have much to say. He had to look for her anyway. Since there was a human body radar, it would obviously be more convenient, right?

Hearing Fang Zheng's words, the girls responded, and while no one else was paying attention, Riri Saotome quietly ran to Fang Zheng and looked at him with a smile.

"Um...Mr. Fang Zheng?"

"Hmm? What's up?"

"Can I go with Lei? After all, you see, she saved my life, and didn't we already have that... mutual bond? Although I'm not quite sure what it means, this means that my fate and hers are connected, and she's been sleeping alone for so many years, I'm afraid she doesn't have any relatives or friends..."

Lei Zi said this in a low voice, looking at Fang Zheng with a pleading expression. After all, she was really afraid that Fang Zheng would never bring her here again because of what happened this time, and Lei Zi was indeed very worried about Lei.

"Sure, no problem."

"real?"

"certainly."

Looking at Saten Ruiko's excited expression, Fang Zheng chuckled. Of course, he would not tell Saten Ruiko that no matter whether the Eddielu Courtyard could be found or not, Lei would probably be inseparable from her. By that time, if Saten Ruiko brought Lei back to Academy City and was seen by INDEX...

When the protagonist has a harem, most of the concubines will be jealous.

I want to see how you clean up this mess.

Lei Zi didn't know that Fang Zheng had this in mind. Now that she knew that she could go with Lei to look for that courtyard, she felt relieved. She hummed a song and returned to Lei's side.

During this time, Misaka Mikoto and Shirai Kuroko were also very curious, and even suggested to Fang Zheng whether they should search the entire city to see if there was anyone who had experienced something similar to Lei. However, Fang Zheng had just scanned the entire city and found nothing. Moreover, they only had a few people at the moment, so it would not be normal to want to search the entire city ruins.

In fact, after they asked Lei, they were surprised to find that Lei didn't know where this place was, because when Lei had memories, there was no such thing as a mobile city. As for why she appeared in a warehouse in such a city, Lei herself had no impression at all.

This surprised Felli as well. If even the mobile city didn't exist, then the world that Rei lived in would probably be more than five or six hundred years away from now...

After that, along the way, everyone listened to Lei's stories about her time. Apparently, the era when Lei lived was not peaceful either, and all kinds of monsters caused a lot of sacrifices. Because of this, humans adopted many methods to protect themselves, including capturing those holy war angels and forcing them to form a bond with them to gain power.

After all, although the holy war angels can exert extremely powerful power after forming a bond with humans, if there is no user, the holy war angels themselves are nothing special. Take Lei in front of us. If she had not formed a bond with Lei, she would be just an ordinary girl with no power. In terms of combat power, she might even be worse than Lei. She is probably at the same level as Hatsuharu without a computer.

So at that time many humans were capturing the Jihad Angels, and that was also the reason why Lei hated humans.

Fili silently calculated what Lei said, and then whispered to Fang Zheng that if Lei was not lying, then the era she lived in should be the "Edge of Doom" era six hundred years ago. It was after that time that the earth dried up, and polluted beasts rose up everywhere, forcing everyone to rely on "mobile cities" to move and survive.

However, Fili had never heard of the Holy War Angels, and she didn't know if there was anyone who could be transformed into a weapon. After all, so many years had passed, and it was possible that Lei was the only one left in the Holy War Angel clan.

Fang Zheng didn't react to this, but just nodded to show that he understood. On the contrary, Feili was very excited. She had always wanted to get out of the cage of the mobile city and explore the outside world. She didn't expect that she would encounter such an interesting thing just after she got out... So, what will she encounter next?

At this time, Fili was already full of anticipation for the future journey.
