(I'm the shell left over after hard work2...... ）

The so-called "opening the door to the underground" may sound like a fairly easy thing to do.

However, as long as you think about the content of this matter from the mouth of Xiang Yue Xihu, then you can already predict how thrilling it is.

This woman's purpose,Although it is "to ensure the survival of the Bailing Hiiragi School Park",But,Even if the main battlefield is in this school park,As long as it can be conducive to the implementation of the plan,Then,Sacrifice one or two key buildings a little,Give up one or two critical areas,Even simply sacrifice one or two groups of desperate students,It doesn't matter to her。

As for now...... This woman is here even more...... I couldn't believe how big it was.

"This ...... What the hell is going on...... Exploded? ”

If you just use shells or explosives, you won't be able to open a huge hole in the ground that suddenly appears like a huge sinkhole, a few hundred meters in diameter, right?

The surface of the earth seemed to be swallowed up suddenly, and even in the sunlight, the whole pit looked black and painful - this was not the point, the point was that the connection to this huge cavity was actually to the deeper part of the earth...... Huge passages.

"That...... It's one of the pathways to the BETA underground base.'"

From the body communicator, Xiangyuexi's explanation was unhurried.

Having already reached the ground, I was the first to take my own unreliable-looking but actually powerful and wing-capable driving armor, but for now, I wasn't going to fly and become a target for the rays.

"That is...... The next break-in is also going to start here, right? However, can you confirm the location of the brood? ”

"That kind of thing...... It's the job of the Sorrowful Emperor's driver.'"

Huh?

"The Four Styles of the Emperor of the Sorrowful Empire" was announced in advance as the core body of this operation, a terrible war weapon with powerful force, and before that, Xiangyue Xihu also said that only this body can complete the task of breaking into the ground and destroying the beta brood.

Indeed, without that kind of monster-like firepower, it might not have been possible to shake the brood, which was so huge in my imagination, but ......

The driver of the "Sorrowful Emperor" chose to ...... What is really hidden?

The mysterious girl Shekatsu, the foolish good person Otono, and the "Mystery Brain Man No. 2" that is kept underground as a secret of the Alternative Project in a bottle...... Well, in any case, I can't imagine anything like a radar in such a combination to find the nest of the brood.

Ahhhh......h Of course, if it is said that "the enemy is found on its own because of the waves of hatred", then the most likely brain is the brain that was stripped of flesh and bones by BETA, but it is just ......

"It's not time to explain the Alternative4 plan, but in short, please make sure to make sure that the area around the entry point is clear."

"What are you kidding about such a large area...... Do you want me to make sure by myself? ”

That's the entire school park's sports field and a large area of combat ground are directly swallowed up.,A huge pit with a diameter of nearly a kilometer makes it impossible for my driving armor to fill it, and I'm afraid it's not enough for this big pit to plug the teeth, right?

What's more, with such a big pit, if there is really a BETA cluster desperately planning to rush into it, I can't think of anything I can do.

The so-called "digging a pit is easy to fill a pit is difficult to fill a pit" seems to be like this? I don't know why, but this strange idea suddenly popped into my mind.

"Well, that's it."

"You're a ghost...... Feed? Hey"

Damn it, that woman unilaterally cut off communications

"Buzz ......"

When I waved my mechanical arm angrily, in front of me, the huge body of the five-person formation, the "Wu Yulei", one purple, two red and two white, had already launched this breakthrough operation.

Such a huge crater is naturally to allow the same huge body to easily invade, and when it goes underground, the underground passage opened up by the BETA will only be more spacious than the ground if it can allow the super large beta of the fortress class to pass freely.

"It's just ...... the words of 'Emperor Sorrow'...... How do you break in? ”

I looked around suspiciously, no matter what, there didn't seem to be a place for a big guy like the "Emperor of Sorrow" to hide, and I didn't see any other mechs approaching this side until the roar of Wu Yulei's huge engine disappeared underground.

"Emperor Poo? Refers to...... That big guy who smashed into the ground before?'

In the communicator, Xia Lu's lovely voice was extremely healing.

The orange "Hurricane", which is flying comfortably in the air at this time, is integrated by the data of the third-generation IS core and part of the fourth-generation IS core data, plus the quasi-fourth-generation mechage "Hurricane" recreated by Xia Lu himself, which is many times better than the previous "Rebirth of the Wind" in terms of performance.

That's why Xia Lu was able to easily deal with the sniper from the beams fired by a large number of gathered rays from the ground as if it were raining down, while still talking to me easily.

"Ah...... But Xia Lu, what are you talking about......"

"The big guy who just fell from the sky smashed into the ground in one go, and this hole was smashed out by that thing."

Accompanied by Lafra's voice, there was also a continuous burst of discussion from the live howitzer carried by the "Black Rain" body, and with such a bombardment, a large area of light species gathered by Xia Lu's yin* was blown to pieces almost without any power to fight back.

Merely...... Compared to this kind of killing as if it was mowing the grass, I was more concerned about the previous sentence.

"Open...... Are you kidding...... Throwing something that big from the sky? ”

Judging from the proportions shown in the construction diagram, the size of the body of the "Emperor of Sorrow" is probably more than any of the bodies present, and if something of this size falls from the sky, the impact it will bring can be known by just thinking about the surprise attack launched by the Sky Angel before.

And obviously, this collapsed passage in front of me is the "masterpiece" of that big guy, right? The question is, is it true that using that kind of thing as a "prop to open the door" doesn't cause any damage to the body?

『…… It's okay.'

Huh?

Looking at the unfamiliar signal connected to the communication channel, I was stunned for a moment before I reacted, because ah, I am not unfamiliar with this voice at all.

"Yes...... Rosy clouds? ”

"Sincerity...... Makoto-san, it was really exciting just now.

"Who made that risky battle for fools?"

When Yin Wu's voice also sounded, it was obvious that this strange signal was a communication message from the Emperor of Sorrow.

It's just that it's too risky, isn't it? Let the mech parachute into the ground or something......

『…… After careful calculations, the infinite force of the Emperor Four's position can neutralize 100% of the impact caused by the high-altitude landing, so it is also the most reliable way to break through today."

Shexia calmly explained the battle to me.

Ralfo position? It's a brand new term...... In short, I'm afraid it's also similar to the Absolute Realm, a super powerful defense system, right?

In any case, it seems that this "Poignant Emperor" is not just what it seems on the surface, it only has a body with super powerful firepower, after all, such a big target, if it does not have a super strong defense, then it can easily be broken as a target.

Only five "Wu Yu Lei", as a combat unit, although it is very powerful, yes, but, if it is cover, in front of the tide of BETA, it will never be perfect, it seems, the so-called "combat core" may really be this performance beyond imagination of the "Sorrowful Emperor".

"But...... This place can't be defended at all, right? ”

The girl who was curled up in my arms moved her body carefully and uncomfortably.

Although I had already asked this incompetent girl to stay in the command room before this, I couldn't convince the stubbornness and willfulness of the void, so now, the drive armor, which was not spacious in the first place, was squeezed into three people at once.

Xuzi, me, another one......

"Lord...... Master...... Do you want a massage? ”

Ah, that's right, even the docile little maid C.C was brought in by the way, after all, since it is a big combat force, it seems a little unreasonable not to bring C.C, and maybe at a critical moment, this amnesiac maid can bring me some unexpected accidents?

"Ahh......h Chengjun is really ...... I'm thinking about strange things at times like this.'"

The black girl who transformed into the school park connected to the strings,Long hair fluttering on one side of my body.,On the other side,It's a pure white angel girl.,As for the ...... on top of my head.。

"Anyway, Serra, wouldn't standing in a place like this make the goal more obvious?"

"I'm not a showy ninja below, but standing taller can better identify the enemy."

That's right...... Well, actually, I just prefer to be in that position with a tight-garment or a skirt-like Kana, as for Serra...... Well, skinny jeans are a good choice.

"Hey, the space is obviously very narrow, so it's really ...... to squeeze this kind of thing in casually."

The void in his arms blushed and protested angrily, as for the content of the protest...... It seems that it was because I had unfolded a magical item that would make the space even narrower under inappropriate circumstances.

"Or else...... It would be better to put this thing in another space, right? ”

"Mixed ...... How can such a thing be ...... now?"

"Goo...... Goo...... Host...... Not...... The host is saying...... Like this...... Goo ......"

"So, even a maid has to see the incident clearly, and then act recklessly, right?"

“……”

I was amusefully silent about the anger of the Void Son, but it wasn't a bad thing to be able to enjoy the services of C.C during the battle, and my mission was only to ......

"Hmm, what's that sound?"

"Also...... It's not the sound of that thing of yours yet."

"It's not that...... I mean......"

In my ears, I don't know when it started, there was a murmuring of songs.

Without warning, the voice suddenly echoed in the ear drum, as if it had ignored the sound insulation of the body from the beginning, and sang a beautiful melody softly but clearly.

"This singing...... It's a hymn mass, isn't it?'

Zhixian's voice also carried inexplicable doubts.

"Hmph...... It's a weak accompaniment to this battlefield.'"

『…… It's very good.'"

Of the two very different comments, I'm naturally leaning more towards the latter, which is the way it sounds, and it's true that the sound sounds a little too lyrical, but in terms of singing alone, it's pretty good.

However, why is there such a song inexplicably heard on this battlefield?

I have the impression that the only one who uses her singing voice as an attack is a girl named Intix, right? However, the stupid nun's words, because the hungry Cheng dù was not enough, it seemed that she still stayed in the command room temporarily with the young man of Shangjo.

『…… Hey, hey? Is it Makoto-san?'

Said that when Ma Dang Ma appeared, but at this time, I was suddenly contacted......

"What's the matter, do you want to fight?

"That...... That song."

"Ah...... What happened to the singing? ”

I listened to the unidentified voices coming from the air, trying to find the source of the song from all around.

Not...... The huge sinkhole in front of me was the first target to be eliminated, after all, I didn't think that the creatures of the BETA would make such a beautiful song, as for the ground...... There doesn't seem to be anything like a guy who can play this kind of vocal music in passing during combat?

『…… That...... That singing voice is...... It's ......

Really, the more critical it is, the more unreliable this guy is when he is numb, and he has to stutter for so long when he can finish everything in one sentence.

"So, why don't you just let Intix sue me for me?"

『…… Be...... Apostle.'"

The next second, the girl's uneasy voice came from the communicator.

Huh?

Suddenly realizing something, I looked up in surprise and looked up at the sky.

Be...... That guy?

With my body, I can't see the apostle's condition clearly from such a distance, but ......

What the hell is that guy going to do when he suddenly makes such a battle? V
