Of course, Arcadia has not been loitering during downtime, on the contrary, they have made so many preparations and emergency plans that the designers of such plans even doubted the need to carry them out now or in the future.
What's happening right now is one of those maniacal plans, designed by the primarily and most talented investigators at the research facility, or as the military like to call them, sinister and gruesome lunatics.
A product fruit of all the combined efforts of numerous brilliant minds full of imagination, talent, and, above all, madness, extreme madness.
They call it the yin yang bomb.
A metal ball that inside contains two different elemental liquids, one of extreme water and the other of extreme fire, separating these two substances is a thin membrane made of materials that you better not know for the sake of your own health mental.
This membrane is thin and extremely brittle, a certain amount of shaking is all it takes to unleash hell.
There is the pleasant and fortuitous coincidence that the vibration caused by the steps of the grade two zombies are more sufficient to fulfill this desired objective.
"Boom!"
Explosion after explosion spread through space, zombies, skeletons, and ghouls exploding to pieces and their fragments flying out and filling the sky, forming an unexpectedly colorful and magnificent scene.
But this was not the end, not even close, the fireworks are only beginning.
The shock waves from the yin yang bombs caused the activation of bombs located further and deeper, specially placed so as not to detonate just by being stepped on.
"BOOM!"
"BOOM!"
"BOOM!"
The destruction caused was fierce and violent, every second, thousands of undead were killed without resistance, the pieces of corpses filling the air offered a sinisterly beautiful and captivating sight worth observing.
At some point, Isabela had a bag of popcorn in her hand as she watched the show with relish.
The rest of the soldiers also enjoyed it, but their enjoyment came more from the fact that each zombie that dies there is a zombie that they do not have to kill, that the bombs of those lunatics wreak havoc! A dead zombie is a good zombie.
All the good has to end, all the explosives exploded and caused destruction, leaving painful wounds on the mighty legion.
What was once a legion of 50,000 became a horde of 30,000, more than 20,000 undead were killed, even some rank 3 captains were swept away by the shock waves and ripped apart.
The hard-won organization was brutally shattered by this single ruse by the very civilization they are on to destroy.
But this tough army won't be stopped simply by this insignificant setback, the mighty rank 4 generals flaunted their absolute authority to subdue the disorderly herd of undead, rearranging them in a matter of seconds.
Between them, the ghoul tyrannically demonstrated his dominance by forcing the other generals to submit with the simple use of his powerful aura.
Adriel looked at this scene with interest, he turned to the person in the scientist's gown behind him, "Tell Fiona and Mateo not to activate the rest of the traps, we don't need them for now"
The scientist did not bother to question, he nodded and went with great speed to where he was ordered.
Meanwhile, the newly rebuilt horde marched towards the Arcane walls with the same skill and discipline as before, it almost seemed that they had not lost half of their troops less than a minute ago.
Finally, the undead crashed into the wall.
"BOOM!"
Unexpectedly, the wall was not shattered by the shocking force exerted on it, in fact, only a few scratches appeared on its robust surface while the wall itself stood firm.
The high-ranking undead did not have time to grasp the situation before calamity descended on their rotten heads.
"BOOM!"
Attacks of all shapes and colors descended upon the herd of dead, tearing the rank 2 soldiers to pieces with almost no resistance, even the rank 3 generals would succumb after taking dozens of attacks head-on at once, defeated in front of the immense variety of powers displayed by Arcane soldiers!
Adriel was ... disappointed.
When the system said that the difficulty of the test would increase based on the strength of Arcadia, it thought that they will face a constant fight for survival, but unless the difficulty of the last tests increases 10 times, there will be no challenge.
Adriel shrugged, his body disappeared and, a second later, he was next to Isabela, who was still enjoying the show with a bag of popcorn in hand.
"I'll take the ghoul and the huge skeleton, you keep the red-haired zombie and the small skeleton"
Isabela stopped eating and joked, "Aren't you sorry to send a delicate young lady to two terrifying monsters?"
Adriel rolled his eyes, Isabela is many things, but 'delicate lady' is not one of them, "Please, at this point I don't even think they will attack you, honestly, I feel sorry for those poor monsters who have to confront you"
After her evolution, Isabela became exponentially stronger and strengthened many of her qualities, but the importance of her evolution comes down to two abilities.
[Heavenly Luck] and [Chosen of the Cosmos].
With [Heavenly Luck], she could sit in the middle of the horde and somehow no attack will hit her, with [Chosen of the Cosmos], most likely they won't even attack her and instead kneel in front of her.
That's how ridiculous those two abilities are, even Adriel has to admit that he's a bit jealous.
Isabela asked another question, "If I tamed those two, would it count as valid for secondary objectives?"
Adriel could not answer that, he has never considered it, neither he nor anyone else.
[It is valid]
A notification appears in front of the two, causing Adriel to sigh, "The system has to add additional rules because of you, and I believe that the anomaly is me."
Isabela smiled before asking again, "And the last zombie?"
Adriel looked away and directed his gaze to the silent general who organized the entire army.
