"However, the earthworm should be no more than two meters in diameter...... what the hell is that big guy?"

"Who knows! Why are you so calm?"

"Alright, okay, don't be so loud, Boss. They don't handle well underground and make a lot of noise when they move. Just by looking at the sound, you can grasp the approximate position. 」

The boss closed his mouth and gritted his teeth so hard that he almost made a sound. He looked angry, and he looked like he was about to wave the gavel in his hand and make a fuss. If he could, he really wanted to blow the head of the monster with his own hands immediately.

"That's it. So, Boss, please stand back. It's coming. 」

Hearing Al lower his eyes and whisper, the boss didn't care to answer, and immediately ran as fast as he could. The vibrations of the ground also approached rapidly, and the water at El's feet splattered throughout. Before the boss could say a word, the earthworm burst out from Al at his feet. Even the boss was terrified when he saw this. Although it was thought that it was impossible for El to be swallowed like this by having mastered the approach of the earthworm, the scene still seemed to be very bad for the heart.

The boss who didn't need to worry about Al saw the moment the earthworm flew out, and cast an atmospheric compression propulsion magic and jumped up. The earthworm also stretched out its body, chasing the El flying into the sky at an alarming speed. However, El accelerated further in the air, escaping the beast's pursuit, and he maintained a leaping position and stretched out his staff Winchester.

"Welcome, please try this!"

Earthworms can dig freely underground, but once they are in the air, they cannot change direction. The two Winchesters fired violently at the carapace at the front of the beast like a grinder, and the fire-piercing spear magically stabbed the earthworm to the ground, causing it to explode in a wave as it was hit.

Even if the earthworm's carapace has the power to shatter even rocks, it can't withstand the magic attacks that fly one after another. A targeted burst of flame pierced through the carapace, causing it to burst, and the subsequent magic burrowed into the large hole and detonated, blasting through the surrounding body tissues with tremendous pressure. Twenty percent of the tip of the slender earthworm burst apart, splitting apart in the air. After a second, the beast ceased all signs of life activity, and the fragments of its body dug into the ground one after another.

"I've kept you waiting. 」

Confirming that the earthworm had exploded, Al flipped over and landed on the ground. The magic absorbed by the atmospheric shock splashes dirt and stagnant water, absorbing the impact of the landing. Immediately afterward, he ran to support the other students and knights who had been attacked by the earthworms.

In order to deal with the demonic beasts attacking from the underground, the knights and students did not adopt a dense formation, but maintained a certain degree of dispersion. The most terrifying thing about the earthworms is that they attack directly below, so they are engrossed in watching the movement.

"Honk carefully!Run if you feel close, don't stop!!"

"Here, watch to the right!"

Earthworms that came out of the ground swept past them as they hurriedly dodged. The earthworms, which are extremely ferocious in the earth, have to burrow into the ground if they want to attack the creatures on the ground, and the excessive force of breaking the ground will cause them to appear defenseless in the air. That moment was an opportunity to attack.

"Bastard earthworm! Don't look down on people!!"

Although the students and knights were not flinched by the surprise attack for a while, once they regrouped, they launched a fierce counterattack. With each wave of their wands, they shoot a ball of flame, blooming in the rain. Earthworms that were struck by the explosion collapsed from the air and fell to the ground, some of which exploded in the air due to the direct bombardment of most magic. The knight and the students took advantage of the fact that the earthworms had no time to escape back into the ground, and quickly delivered a fatal blow.

The earthworm's skin grows very strong to withstand friction against the ground, but it is not hard enough compared to the front carapace. The Boss ran to a shattered earthworm that had been hit to the ground by the Flame Ball, and smashed the hammer in his hand with all his might.

"How dare you attack our people!!"

This hammer unleashed the powerful muscles of the dwarves to the extreme, and struck the part that was not covered by the carapace. The sledgehammer swung down with strong kinetic energy, breaking through the skin of the demonic beast. The skin of the monster cracked open because it couldn't bear it, and the tip of the hammer was buried inside. The infiltrating and spreading impact smashed the internal tissues to pieces, and the body of the demonic beast was slammed into two pieces. The earthworm, which had no vocal organs, spasmed violently as if it were screaming silently, and finally fell to the ground weakly.

The boss who confirmed this pulled out the hammer buried deep in the demonic beast's body and covered in bodily fluids. He waved it and put himself back in his stance.

"Let the horses come! Next, bring them all over! I'll beat it far away no matter how many comes!!"

It is said that the invincible momentum, not to mention the Warcraft, even the students are extremely frightened.

The small earthworms were defeated one after another under the counterattack of the knights and students. They were able to deal with small monsters calmly, actually thanks to the hard work of the Phantom Knights troops.

At a distance from them, the giant earthworm that El called "The Leader" was on a rampage.

As soon as the Phantom Knight troops realized that the earthworm leader was more interested in Phantom Knight than humans, they immediately distanced themselves from the knights and students. Earthworms generally do not have a high IQ, so the leader is completely hooked and cleverly led into the forest.

A giant mouth with more than half the diameter of the Phantom Knight rampage, crushed equally on the ground and in the forest. The woods that get in the way of movement are a disadvantageous battlefield for the Phantom Knights, and even if the leader is different from the living people, there is still no one to compete with. They understand that their side is at a disadvantage and must fight far from their fellow travelers.

"Damn!!"

The Trestal 1 piloted by Haiwei roared and rushed forward. The two backs of the arms spread out on their shoulders let out a low roar, and a series of magic bullets fired left arcs in the air. Although the magic bullet directly hit the leader's body, it was worthy of being a behemoth of more than 100 meters, and its endurance was extraordinary, and there was no obvious effect.

"What the hell! I hit it and I didn't get hurt, isn't that a foul!?"

Against the bosses who are moving forward with their long and thick bodies, they can only give scattered attacks. The mass of the enemy is too large, and the damage that can be dealt by a simple magic hit is limited. And since the magic guide armor is not effective, it can only rely on Gardatoya to slash with a sword, but even the sword of the Phantom Knight can't inflict a severe blow on the leader.

Compared to the Phantom Knight, the boss's attack is deadly. One of the planes that had been nearly captured by the leader's assault immediately set up his shield, and then a sharp noise resounded all around, and a large number of sparks erupted from the contact surface between the leader and the shield. The carapace, which rotates at high speed, slices away the surface of the shield like a file, and shreds it as easily as a piece of paper.

Gadatoya was knocked away by the leader's assault, and his shield and left arm were reduced to debris in place of his body—a blessing in disguise. Allies immediately run towards the fallen mech.

"Are you alright!?"

"Well...... shield and left hand are gone, but they can still move. You can swing a sword!"

"Trestal, everyone assemble with me!"

Amid the roar of the leader's shattering of everything, Edgar shouted through the built-in speakers. The Treistal forces burrowed through the leader's furiously wriggling body and gathered around the second aircraft piloted by Edgar.

"What are your plans? Have you come up with a good idea?"

"Hmm. Dispersing attacks doesn't have much effect, so it's better to concentrate artillery fire. Everyone attacks from the front in a "quadruple form". We're going to get that guy to stop. 」

Although it was to concentrate firepower, he did not expect Edgar to propose an attack from the front. Gadatoya's driver would probably wonder if he was in his right mind, or wouldn't let him propose it at all. However, the students believe that the new machine has a way to achieve its purpose. They smiled brightly in the driver's seat and nodded vigorously in understanding.

"Alright, let's have a fight! 」

Trestal put away his melee weapons and threw away his shield. In each hand, he picked up a magic guide armor that was inserted on his waist, and further unfolded his back armament. This state of lifting a total of four magic guide armors is a veritable "four-in-a-row form", and it can be said to be the true ability of Tresthal, who can use most magic guide armors at the same time.

Since most of the Phantom Knights are concentrated in one place, this intrigues the boss - it locks on to its target and begins to assault. Seeing Trestal gathered in the direction of the tumbling beast, a horse trainer from Datoya hurriedly issued a warning:

"What do you want to do!?Danger, get out of the way!"

"We're going to focus on the magic guide armor and shoot!If that guy retreats, I'm going to trouble you to chase after him!!"

The Tresthal troops lined up as if they were about to welcome the leader, aiming the sights on the illusion projector at the center of the leader's mouth. It was so close that it could never be missed.

"Shoot!!"

At Edgar's command, the five Trestals immediately moved. A total of 20 guns - equivalent to more than 10 magic armors of an ordinary Phantom Knight firing at the same time. Backed by a massive amount of mana stored in the plate-like crystalline muscles of the mana storage armor, a surprisingly dense rain of bullets spewed tongues of fire through the rain.

The magic bullets dragging the dazzling tail feathers struck at the leader in unison, and the carefully aimed magic bullets shot directly into the leader's big mouth. No matter how much it eats, it can't swallow the magic bullets emitted by tactical-level magic. The front of the leader was suddenly shrouded in brilliant sparks. Tresthal's concentrated rain of bullets destroyed rows of carapaces, forcing the menacing leader to slow down.

At this moment, even the leader twisted his body in pain. The blast caused the beast to dig into the ground in an attempt to escape underground. It's a pity that the magic blow just now should be enough to shatter the front end of the ground and suffer a lot of trauma. The lack of parts prevented him from digging into the ground, and his huge body just rolled and writhed on the ground.

"Now, pursue!Deal with it now, don't let it escape!!"

None of the present had spared a foe full of vulnerabilities. Gadatoya struck with swords and spears, and the Trestal troops, though they had lost a considerable amount of their magic power, squeezed out the last of their strength, grabbed their melee weapons and rushed forward, smashing their swords or spears into the wounds inflicted by the strikes. The leader, who struggled to flee underground, soon became in tatters.

At this moment, a Trestal vigorously swung his two-handed axe gun. The rope-shaped crystalline muscles that spread all over the body play a melody like a stringed instrument and release great power when it is pulled strongly. The axe spear with violent speed and centrifugal force roared into the body of the demonic beast, and the bubbling body fluids mixed with the rain and soil, spraying everywhere.

Finally, the leader who couldn't bear it cracked widely, and broke in half with a pop. Even if it is as strong as a leader, this blow is enough to kill. The huge body, which had lost its vitality, fell to the ground with a loud thud, unable to move again.

The riders who had defeated the mighty beast raised their mech's hands and cheered loudly. However, they only basked in the joy of victory for a moment, and soon returned to the original attack to support the knights and students. However, by the time they stepped out of the forest, most of the earthworms had been wiped out by the knights and students in a furious counterattack. Sure enough, it's still the leader who is more difficult to deal with.

In this way, it didn't take long for the streets to return to their original calm.

"Alas, the stinky earthworms have caused me so much trouble. 」

After defeating the big and small earthworms, everyone breathed a sigh of relief, and the boss complained with such a stinky face. In front of him were wagons reduced to wreckage and gnawed corpses of horses.

"Can you keep the carriage that moves everyone?"

"No, it's really not something that can be repaired in three or two strokes. No matter how quickly you fix it, if half of it can move, thank God. Besides, we're riding forgers, so we're not very good at carpentry. 」

The inquiring knight had somehow expected such an answer, and he crossed his arms in anguish. For them, the loss of most of the carriages they used to move was arguably the biggest blow of the battle.

"No way, we have to transport the injured first. Let the running carriage carry the wounded to the Kazadexiu Fortress first. The car is okay but there is no horse? Let the Phantom Knight pull it. A short walk from here there is a village, and we'll get there first. If only I could borrow some means of transportation......

Everyone followed the knight's orders and began to act. The Boss angrily kicked the earthworm's corpse away, but that didn't make it any better. The only thing they were thankful for when they were about to move on foot was that the rain gradually became much lighter.

As a result, the group still couldn't find a means of movement in the village, so they had to ask the Kazadexiu fortress to send a carriage to pick them up. After that, they encountered the Demon Beast several times, but they didn't meet the big guy at the boss level, and they could kick it away with the combat power of the Phantom Knight. In this way, although a few days later than the scheduled date, the students and Trestal finally gathered at the fortress of Kazadxiu.

"Okay, let's start the overhaul of Trestal!Especially the back armament should be carefully watched!!"

The boss and the others, who had moved into the fortress workshop, immediately began to overhaul the body. After a fight with the unexpected big guys, Trestal needs to be fully prepared - after all, they are here to show Tresthal. The maintenance team led by the boss carried out the refurbishment of the airframe without sloppiness.

The forgers of the fortress looked at the scene with great interest. They also got the rough idea of what happened. Originally, I was half expecting and half skeptical about the new type of machine developed by the students, and I was not impressed with them until I saw the new type of machine with my own eyes. The knights of the Guards who actually participated in that battle were even more pleasantly surprised, and there were many of them who wanted Trestal to be a standard production machine, or at least wanted to add the same function. They secretly look forward to the day when it will come, and now they are just quietly watching the work in front of them.
