This is not the date I wanted.

However, when Mengyue saw the happy expressions of her good friends, Yui and Yakuya, she slowly loosened her fists.

Watching Shidao and his group slowly leave, Mengyue looked up at the sky. After a long time, she sighed with a sense of relief and bitterness.

"...As expected. Seeing it will only ruin my mood."

20 Different Worlds, Same Person (V)

==============================

In September, the hot summer vacation is over and it is time for school to start.

"School..."

Passing by the gate of Laichan High School and looking at the students attending classes in the teaching building, Mengyue couldn't help feeling a little nostalgic.

Although she had graduated from high school a long time ago when she was still "he", it seems interesting to experience what the difference is between high school life in Japan and the cramming-style teaching in China.

but……

"Well... forget it. It would be troublesome if I made a promise with that harem man because of that. And my future self has experienced it once, and it seems to be just like that."

Meng Yue sighed and shrugged, then turned and left.

Since coming to Tiangong City, Mengyue did not choose to leave, but settled here directly.

In my future self's memory, in the next few months, many serious incidents will occur in this city because of DEM, the elves, and Ratatoskr.

The citizens were brainwashed by their idol's violent temper, causing the city's functions to be paralyzed; the harem man failed to protect his harem, causing the woman to turn evil and go berserk, slashing the earth; a certain airship was hacked by the enemy because its defense was too fragile, and it almost fell into the city; the internal struggle of the enemy forces resulted in the fall of several artificial satellites, intending to raze Tiangong City to the ground, and so on...

Meng Yue couldn't help but think of a certain Dongbi city that was as peaceful as ever.

To be honest, Meng Yue would definitely stay away from such high-risk areas and try to stay as far away from them as possible.

However, if he dragged his friends into those disasters, it would be a different story. Moreover, monitoring whether the harem man bullied Yakushiya and Yui was one of the reasons why Meng Yue stayed here.

(What a contradiction...I am.)

Meng Yue couldn't help but think with some self-mockery.

Although she knew that she didn't want to have anything to do with Gokawa Shido, she still took the initiative to find Yui and Yakuya because she was lonely.

She clearly hated the harem and knew it was a place of trouble, but when she thought of her friends' difficulties, she actually took the initiative to ask them to find the man in the harem.

"I've been waiting for you for a long time, Miss Mengyue."

In front of him, the most evil elf, Tokisaki Kurumi, was waiting for him with a smile.

"Well, next I'll have to trouble Miss Mengyue to lead the way and take me to DEM to find the imprisoned elves."

"...Hi! I will definitely keep my promise."

After responding to Kuang San, Meng Yue couldn't help but scratch her long brown hair and sighed helplessly.

(Really…what on earth am I doing?)

————————————————I am the dividing line between invasion and infiltration————————————

DEM Japan Branch, Second Office Building, Advanced Technology Research Institute.

"Stop, what are you two doing here?"

"Excuse me, we're here to deliver food, but this building is too big and we got lost here accidentally. Can you tell me where Miss Jessica Bailey's office is?"

Looking at the magician who was wary of her, Mengyue picked up the ramen in her hand and showed a 100% sunny smile for welcoming guests.

"Captain Jessica? She should be training in the main office building right now."

The magician frowned, looking at the two girls in delivery uniforms, and lowered the gun in his hand slightly.

"This is the second office building. You've come to the wrong place... Wait!? This is the seventeenth floor. How did you get in without a special ID card--"

By the time the magician realized something was wrong, it was already too late. Kurumi's shadow silently spread to her feet.

Just like that, the magus, who was deprived of a lot of physical strength, lost consciousness and fell to the ground without even being able to shout "invader".

"Good night, young lady."

Kuang San whispered this softly, looking at her own position, with a hint of eagerness and anticipation in her eyes.

In the previous world, in order to find the "elves" imprisoned by the DEM club, Kurumi took advantage of the chaos created by Shidao and Miku in the DEM club and came here with Mengyue.

However, they arrived too late, as the imprisoned "elves" had already been transferred to other places.

So this time, after Kurumi got the news that "Material A" was transported here from her clone, she immediately found Mengyue and asked Mengyue to help her sneak into DEM Club on the condition that he would protect the Yamai sisters and Gokawa Shido during the Miku incident.

"You really helped a lot, Miss Mengyue. How can I repay you? My body?"

"Stop it. You're doing me a big favor by not bothering me."

Meng Yue rolled her eyes in annoyance, obviously not taking Kuang San's words seriously. She sighed and came to a wall.

Her fingers gently slid across the smooth metal plate. With the memories of the previous world, Meng Yue quickly found the hidden touch screen membrane.

Originally, this was a combination lock made up of multiple layers of passwords including fingerprints, retina, DNA, etc. Although it was a very tricky thing for ordinary humans, for Mengyue, this thing was no different from a virtual thing.

"But then again... this reaction is too slow. Are all the magicians in DEM such noobs?"

During the unlocking process, Meng Yue glanced at the magician lying on the ground and couldn't help feeling speechless.

Before invading here, Meng Yue had investigated the structural design drawings of the building in advance to confirm the shortest route, and used her abilities to tamper with the images of the surveillance cameras, used ventriloquism to trick the patrolling magician, and also hacked into the building to crack the combination lock... In the end, she deliberately revealed this flaw to test the other party's vigilance.

"I say... don't you think our invasion went too smoothly?"

Meng Yue couldn't help but frown in confusion.

If DEM's security is really limited to this level, then I can just sneak into the DEM boss's office and kill the final boss with one sword, thus saving myself a lot of trouble.

But if the problem could really be solved so easily, I would have done the same in my previous world.

"Really? I think it's normal. After all, no one would have thought that two elves would sneak into the magician's base in broad daylight."

Seeing Meng Yue's suspicious look, Kuang San shrugged with a wry smile.

To be honest, DEM's guard was definitely not relaxed. But the only thing he could do was to see how unruly this elf was to humans.

First of all, the security system as the first line of defense is of no use to Mengyue. In addition, Mengyue's habit of making full preparations before taking action also allows her to react immediately when encountering emergencies.

Although Kuang San was confident that she could sneak in by herself, it was completely impossible for her to sneak in as quietly as Meng Yue and quickly penetrate into the enemy without causing any commotion.

It has to be said that the title of the most dangerous elf to humans is well deserved.

"Yeah...too."

Meng Yue showed a somewhat subtle expression. But it was true that DEM had no idea that elves would invade, and the elf transportation route called "Material A" was only known to a few high-level people in DEM. Even she and Kuang San knew the existence of this secret room because they investigated this place in the previous world. The magicians here didn't even know that there were elves imprisoned in this building, so it was naturally impossible to have as strict guards as the main office building.

(Maybe I am really too neurotic.)

Putting aside the uneasiness in her heart for the time being, Mengyue quickly unlocked the combination lock of the hidden room, and a secret passage appeared in front of Mengyue and Kuang San.

She also disarmed the traps inside. Just as Meng Yue was about to go in, a sense of incongruity suddenly came over her, forcing her to stop.

In the previous world, when Meng Yue and Kuang San came here, although they did not see the imprisoned elves, there were indeed residual spiritual power fluctuations left after the use of spiritual power.

But this time, Meng Yue couldn't even feel the fluctuation of spiritual power, let alone the presence of elves inside.

(There is indeed a problem!)

Meng Yue was about to tell Kuang San to retreat. However, Kuang San lost his composure in a hurry, and did not notice the incongruity, and rushed into the room quickly.

That idiot! Meng Yue couldn't help but curse inwardly and quickly summoned the angel.

"Ratziel (Sage of the Dawn)!"

[Calculation begins——Future prediction starts.]

Vision, hearing, touch, smell, sixth sense - all the information that the body can collect is now collected by the Dawn Sage and processed at ultra-high speed. The next moment, a scene like this appeared in front of Mengyue.

Suddenly, a laser blade swept out, splattering the room with blood, and rolling on the ground - Tokisaki Kurumi's head.

"——Kuang San!"

After a loud roar, Meng Yue almost subconsciously kicked her feet and stood in front of Kuang San in an instant, using the Sage of Dawn as a shield to block her body.

Hiss!

The next moment, the waist of the longbow and the laser sword collided violently, and fierce sparks flew between the two.

"Throat? What an excellent reflex ability."

Seeing that his long-prepared attack was blocked, Alan Mathers' eyes showed a light of surprise.

You know, this was a sneak attack by the strongest magician who deliberately concealed her murderous intent. According to her idea, she could kill the "nightmare" and subdue the "hacker" in an instant.

"Ms. Mengyue?"

Kuang San couldn't help but look at Liang Yi Meng Yue in surprise. However, Meng Yue didn't respond to Kuang San at this time, but looked at Allen who was confronting her with a serious face, and said sarcastically.

"Oh? The strongest magician is actually able to ambush here and do such a despicable thing as a sneak attack. Is the world going to change? Or is he too angry at work and his cycle is out of balance?"

"…What you think of me has nothing to do with me. I am only following Ike's orders."

Alan raised his eyebrows slightly and answered in a very calm tone.

"Although Ike asked to capture him alive, but... we should still chop off his limbs just in case."

A dangerous woman. Feeling the fierce murderous aura coming from the other party that was almost materialized, Meng Yue's mouth twitched slightly.

"Sorry, I'm not interested in messing around with you."

Since the elf that Kuang San is looking for is not here, Meng Yue naturally has no reason to stay here for long.

"Lightning Spear!"

The bowstring was pulled, and dense lightning shot towards Allen in an instant.

"it's useless."

Alan used the protective shield opened by the random field. The blue and white electric light seemed fierce, but in fact it did not have much power and was easily blocked by the protective shield.

However, just as Alan was about to attack, the room suddenly became dark.

Only then did Alan realize that the opponent's real target of attack was not him, but the light in the secret room.

"Raigun (A Certain Scientific Railgun)!"

"——!?"

Hearing Meng Yue's voice, Alan, who temporarily lost his vision, reflexively took a defensive stance.

However, the expected attack did not come, and instead, there was a strong shaking of the ground.

"not good!"

Alan quickly turned on the lighting system of his mecha, but at this time, Liang Yi Meng Yue and Tokisaki Kurumi had already disappeared, and all that was left was a pit that was penetrated by the electromagnetic cannon and led directly to the first floor.

"Damn it! Don't even think about running away!"

Seeing two living elves escaping right under his nose, Alan felt that his dignity was greatly challenged.

"Okay, that's enough, Alan."

Just as Allen was about to continue chasing, a man in his thirties with sharp gray hair suddenly walked out of the darkness and called out Allen.

If Meng Yue had not chosen to escape directly, she would have been able to recognize that this man was the executive director of DEM - Isaac Westcott.

"Just now, the magician downstairs sent a report. After escaping from you, the Hacker and Nightmare disappeared right in front of them."

"…Sorry Ike. It was a mistake on my part."

Gritting his teeth unwillingly, Alan couldn't help but apologize self-blamingly.

"It's okay, Alan. Don't hold yourself accountable. You did a great job."

Westcott chuckled and waved his hand, looking unconcerned.

In fact, this is true. Westcott observed it very clearly in secret. It was not that Alan did not do well, but that the Hacker's elf made a judgment too quickly and decisively.

At the beginning, Westcott imagined that the Hacker would use her best measurement to invade Allen's mecha, and then Allen would use the random field to cut off the wireless communication, and then capture the Hacker while the other party was at a loss.

However, he had no intention of attacking, nor did he choose to use hacking technology to invade Alan's mecha. It was as if he knew in advance that his method of cracking the manifestation device would not work on Alan. When the other party realized his whereabouts, he knew that it was not appropriate to stay here for long. He had no intention of fighting and chose to escape directly.

The moment he blocked Allen's sneak attack just now, the opponent's reaction was too fast, so fast that Westcott couldn't help but wonder if the opponent had predicted the future.

"Whether it's the method to crack the manifestation device that he learned from somewhere, or the extraordinary reaction and judgment just now... this elf... is really incredible."

Walking to the big hole blasted open by the Hacker, Westcott touched his chin and muttered to himself thoughtfully.
