A dense black mist layer shrouded the sky.
In such an environment, releasing fireworks would make them even more brilliant.
So, one by one, enormous shining fireworks bloomed within the black clouds.
Countless shining light points trailed luminous tails as they radiated outward in all directions.
These light points, upon touching the black mist, continued to bloom into dazzling sparks.
The scene was magnificent.
But it wasn't over yet. Since the radiation was omnidirectional, a large number of light points fell toward the ground.
Thus, an even more brilliant scene emerged—numerous light beams falling from the sky, as beautiful as a rain of light.
But such beauty was indeed deadly.
Just as when industrial pollution becomes too severe, acid rain easily forms when it rains.
Highly acidic raindrops falling to the ground, onto any substance, would cause a certain degree of erosion.
The erosion level of these light points was far beyond what acid rain could compare to.
The erosion from these light points was even more terrifying than a rain of lava from a volcanic eruption.
The fortresses on the ground, capable of defending against tank armor-piercing shells, upon being hit, were like plastic foam doused with red-hot molten iron—rapidly melting, with some materials even vaporizing.
Those giant machine lifeforms, thirty meters in size like small mountains, under the shower of these shining light point rain, were like candles drenched in boiling water.
Or perhaps, like mud dolls rapidly melting into slurry when washed by rain.
Additionally, the huge mechanical factories the size of towns, under this light rain, had their protective shells looking like ant nests—densely perforated with holes everywhere.
Especially under the more intensely blooming fireworks, they transformed into giant cheese.
As for trees and other flammable materials, they naturally ignited instantly upon being hit.
In the blink of an eye, the ground scene made those witnessing it think of one description—a lava hell, with steam rising everywhere.
It could also be described as the earth being boiled.
And now, the sky that had seemed densely covered with dark clouds had mostly cleared up.
Those dark clouds seemed to have been vaporized.
"What kind of incendiary bomb is this?"
Teletha, shocked by this scene, couldn't help but mutter.
Earlier, during the battle against the giant machine lifeform, by comparing the environmental damage, she had estimated how powerful the firepower of the YoRHa androids' aircraft was.
And such power couldn't effectively break through the metal shell of that giant machine lifeform. So if such machine lifeforms were in her world, she dared not imagine what price would have to be paid to destroy them.
And now, under this rain of light, these things were rapidly dissolving—how high must the temperature be?
She didn't think this was caused by ammunition under chemical reactions.
Could this rain of light be plasma?
If so, then those earlier grenades were actually plasma grenades.
Imagining such an attack in a military operation against actual humans made Teletha's scalp tingle.
That scene would be even more hair-raising than the carpet bombing of white phosphorus bombs and cluster bombs.
Just imagining what would happen to a human body made her instantly nauseous, and she immediately stopped thinking further.
Hell lay ahead; it was better not to open that door and try to glimpse the hellish scene inside, only to torment herself.
....
Currently also online was an ID—Dr. Kouzuki, who was Yuuko Kouzuki herself.
She was watching this war with a somewhat grave expression, observing this special weapon codenamed [Fireworks].
This special ammunition would definitely be effective against the extraterrestrial life forms in her world, the BETA, with their extremely tough bodies and vitality.
Especially the Destroyer-class and Fort-class, these two types of BETA were most likely to tear through human defense lines.
The Destroyer-class BETA, a large species serving as the vanguard of the BETA group, could charge forward at a speed of 170 kilometers per hour, destroying all objects in their path.
The frontal armor shell of this type of BETA was extremely solid, capable of withstanding large-caliber artillery attacks and possessing a certain degree of regenerative ability.
The hardness of its shell reached Mohs hardness 15!
Considering that diamond's Mohs hardness is 10, and this shell was so many levels higher, one could imagine how solid it was.
It wasn't something that any ammunition could easily penetrate.
If the ammunition codenamed Operation Fireworks from the world in the current war scene could be mass-produced in her world, and if the universal fundamentals of both worlds were similar, it would definitely easily melt these monsters' outer shells.
"Truly worthy of the technology Lord Ejie brought..."
"6O, talking too much, do you want to be destroyed?"
A2 suddenly interrupted with such a murderous voice in the communication channel, cutting off the words of someone named 6O.
What did that mean?
Pupils suddenly widening, Yuuko Kouzuki abruptly stood up, then heard a noise—a whimper.
She diverted her attention slightly to reality, seeing a petite girl in front of her, who seemed to be trembling a bit, startled by her.
"Kasumi, can you tell what I'm thinking right now?"
Yuuko Kouzuki suddenly asked this seriously.
The silver-haired petite girl before her, Kasumi, was a product of Alternative III, created from an artificial womb with super-perceptive abilities.
After the Alternative III plan switched to Alternative IV, before the girl was sent away, Yuuko Kouzuki brought her to her side to assist with Alternative IV.
"Just say it directly, it's alright."
So, after Kasumi's statement, Yuuko Kouzuki was slightly disappointed, unable to perceive the Super-Dimensional Channel group.
However, when she was excited just now, this child had somewhat read some content from her brain, so she was a bit confused about whether she was overworked, causing her brain to be a bit chaotic.
"Kasumi, please continuously read my thoughts from now on."
Yuuko Kouzuki also decided to try to see if she could successfully connect this child to this Super-Dimensional Channel, to become a member as well.
After giving this instruction, Yuuko Kouzuki reorganized her thoughts.
The words of 6O just now seemed to suggest that the weapon in Operation Fireworks came from Lord Ejie.
And that Ejie was, of course, the fellow with the ID Golden Toilet. Could the technology from his world be applied in A2's world?
Was this technology the same as the grenade that blew up that large machine?
It had only been a few days, yet production had scaled to this level.
What if it was brought to her side? Could it also be easily produced?
Not just that, but perhaps A2's world technology could also be universally applied?
Thinking of this, Yuuko Kouzuki's breathing rhythm changed!
This might be the hope for this world.
So, the next opportunity for a cross-world invitation couldn't be missed.
