I Became a Hive Mind in the Game

In the middle of the great plains located in the south of South Pyongan Province, there is a huge lake formed by groundwater springing up.
As water is a very precious resource, naturally this lake is considered the best strategic point, and therefore, the ruler of the plains would reside at this lake—thus, at this best strategic point of the plains, an Orc fortress is located.
The stationed forces are truly the main force of the Orc army. It consists of the Orc Lord, the chiefs and shamans of the 17 most powerful tribes, most of the medium-grade and higher Orcs and the low-grade Orcs supporting them, and the monsters that are their livestock and mounts.
10,000 Orcs and 20,000 mounts. As all the main forces of the Orcs, that is, the professional warrior class, are deployed, this fortress also shows a scale befitting that.
This huge log fortress, made by cutting down tall and straight trees growing in the plains, is centered around a long and high palisade that encompasses the entire lake.
A total of 19 watchtowers are installed throughout the palisade to observe the surroundings, and these watchtowers are always manned by about 7 Orc archers watching the surroundings.
And this was no exception for the 9th watchtower, located at the northernmost point and thus called the Winter Watchtower.
“Gruks, bored…”
“…You’re not the only one bored, so for Zebabal’s sake, shut up. Idiot Gruks.”
“Gruks not idiot!”
“So what!”
These archers, showing typical Orc-like camaraderie, were passing time watching the stupid antics of the new recruit Gruks, who had just joined after one of the previous archers died in an accident.
“Why did this guy pass the test?”
“Did his mom give it to the examiner?”
“Stop with the disgusting talk, Churuk. It’s almost lunchtime.”
“So what, Korus.”
These archers bickering all day long, though it might not seem so, surprisingly all know about the great defeat in the jungle.
Therefore, according to principles, those on duty at the northernmost watchtower closest to the jungle should always be vigilant of the surroundings, especially the north, and shoot arrows the moment they spot any suspicious movement, but…
Remember. You shouldn’t expect such diligent and honest performance of duties from Orcs with an average intelligence level roughly equivalent to that of a marine.
Throwing their bows somewhere aside and bickering with each other, they’re looking forward to lunch soon rather than being vigilant.
…Let’s keep it a secret for the honor of the Orcs that just by not leaving the watchtower for work performance, they already possess the top 10% of character and personality.
“I’m—hun—gry—!!!”
And while they were on duty making a noisy commotion.
“…Huh?”
Korus, the most senior among the Orc archers, realized at some point that the watchtower they were in was vibrating, but this never left his mouth.
Whoosh—BOOM!
Hundreds of huge rocks flying from far away collided with the palisade, shattering it to pieces, and this was no exception for the watchtower.
The rocks that hit the upper part of the watchtower, that is, where the Orcs were located, not only destroyed the building but also crushed the Orcs inside, and immediately after that. The beings who threw the rocks from beyond the horizon began to charge.
KRAAAAAAAAAAK—!!!!!
KIEEEEEEEEEK!!!!
HOROLOLOLOLOLOL—!!!!
Letting out indescribable roars, thousands of humanoid monsters charge towards the fortress with bloodshot eyes flashing.
Jungle Trolls, Goblins, Sugarglidemen, Ogres, Crockmen, and various other humanoid monsters, despite once being in opposing relationships, pay no heed to such things.
This advance, which could aptly be called a mad charge, naturally drew attention from the start as it made a splendid entrance by breaking the palisade, and thus—warriors on standby rushed in to stop these humanoids.
Most of the Orc warriors stationed at the fortress are composed only of renowned or exceptional warriors from each tribe, so they are all tough warriors with a minimum of grade 7 and over 30% being medium-grade.
In addition, because these are the Orcs who originally stood at the vanguard of the Orcs attacking the Lizardmen, they are well-armed with looted advanced weapons and equipment from the Lizardmen.
Of course, over 7,000 humanoids are burdensome, but as long as they abandon intelligent movements or use of throwing weapons typical of humanoid monsters and charge like animal-type monsters, it shouldn’t be too difficult to handle them, but…
Ku, kuaaaaaak!
Crunch!
KIEEEEEEEEEEEK!!!
As these humanoids are consumed by madness, the story changes.
The humanoids, charging without caring what happens to their bodies, biting and clawing, attacked the Orcs wildly until they were completely unable to move due to their breath being cut off.
While Ogres and Jungle Trolls face Orc warriors who have evolved into medium-grade monsters or low-grade Orcs in formation, Goblins swarm in large numbers, clinging to low-grade monsters to overcome their disadvantage in weight class.
A chaotic battle of killing and being killed broke out as monsters consumed by madness charged in without sparing their bodies, but as warriors from the rear kept joining, the scales were gradually tipping in favor of the Orc side.
‘…It’s a mess.’
And there was someone who showed such a reaction upon seeing the two humanoid groups visible in the distance—
[Advance, Seri.]
‘Yes, captain.’
It was the being now called Seri, who started moving the army according to the orders of the Hive Queen, whom she calls captain.

※ ※ ※

Seri. The commander leading the Drakemen was an unidentified being in human form, not exposing any skin at all.

She wears black armor made of a large amount of nanomachines and the highest grade materials all over her body, with silver fur and a cape fluttering behind her back.
On her head, she wears a helmet with horns that look like animal ears, and in her hand, she holds a two-handed sword that makes one think this might be what a magic sword from fantasy novels looks like.
And she rides a monster resembling a horse wearing armor similar in design and form to her own armor, its name is Ironbreaker.

Nanomachine Horse Armor(A), Charge Hammer(A)

Its appearance is simply put, a giant black horse wearing full-body black horse armor. It has an appearance mostly similar to an ordinary horse, but the thorny wire tail at the end and the curved devil’s horns growing on its head prove that this horse is a monster.
Its legs (hooves) are equipped with large and beautiful rechargeable shockwave-generating close-range weapons called Charge Hammers (weapons), and the horse armor is no different from being assimilated with the skin and is a masterpiece that can change its form into various shapes.
Even the greatsword held by her riding such a fine steed(?) is definitely not ordinary, the greatsword is a grade 3 monster called Anitheus.

Psychic Sword(A)

Anitheus, a living sword that freely changes shape and assists the user with psychic abilities as an ego sword, is the best weapon, and she who wields such a dangerous weapon-monster is skilled enough not to be controlled by the sword.

Anyway, enough boasting, now it’s time to move according to orders from above.
‘Let’s go, Ironbreaker.’
[Neigh (Understood).]
Skillfully giving instructions to her mount, she immediately issued advance orders to the Drakemen through the Hive Mind network she was connected to, while simultaneously dispersing the auxiliary Lizardmen forces in all directions.
And after briefly watching her comrades start moving according to orders, Seri infused energy into her weapon Anitheus to change its form into a cavalry lance and then—
《—Let’s go!》
Breaking out of the concealment field hiding the Hive Mind’s army, she charged with all her might into the flank of the Orc warriors who had been fighting with the humanoid slaves for a while.
Thud—!
