Alan and the others stood up, and Ke Jiesi said indifferently: "You guys are really lucky, come with me, it's time for a long time." ”

The curiosity of the crowd followed him out of the conference room, bypassing the parts workshop of an arsenal and turning into the large playground. The floor of the large playground is constantly shaking, and from time to time there is mud and sand spewing out of the ground. Kirgeth grabbed a soldier passing by and asked, "What's the situation?" ”

"Two burrowing worms and a hundred knife ants, sir!" The warrior replied.

Korges let him go, and said to the Alan group behind him, "This is a common occurrence, the burrowing worms will sneak into the base from the ground, and the knife ants will follow the passage opened by the worms. ”

Alan lost his voice and said, "Isn't there a lot of holes under the base?" ”

"It's not that strict." "The rocks in the Blood Eagle Heights are so hard that even the burrowing worms can't open their way at will. There are at most three to five passages underground, and the burrowing insects all pass through the original passages of guò and then break through the ground. As for the aftermath, oh, here they are......"

The playground rumbled and shook the sky full of mud and dust. A hundred-legged giant worm poked out from the ground, its mouthparts full of broken teeth and its sharp cry. Another burrowing worm also broke through the ground not far away, and the two worms writhed vigorously and crawled up from under the crypt.

On the playground, several teams of fighters covered the past. Seven or eight of them were machine guns, and one or two were using flamethrowers to shoot dragons at the drillers. As soon as the fire dragon landed on the giant insect, there was a sizzling sound, and the insect's grease burned at a speed visible to the naked eye, and soon the burrowing insect fell under the machine gun and flames.

"The burrower has plenty of fat and a very low ignition point, so it can be ignited lightly. To add up, the fat of this bug can be extracted/refined and processed to become a liquid energy source that we can use on the Underworld Star. Kirgeth said casually.

After taking down the two drillers, a non-commissioned officer shouted for orders, and several teams of soldiers rushed towards the passage opened by the drillers. A reddish-brown knife ant suddenly appeared in the passage, and a pair of sharp feet of the knife ants swiped wildly, and the soldiers in the front row met it with a long knife in their hands and pressed the knife ants back. Behind him, his colleagues interspersed with each other, and the machine guns fired in unison, and the bullets rained down and bombarded the crypt passage.

After a round of fire, a soldier threw a hand/grenade down the passage. Immediately, an orange flame exploded in the passage, and as soon as the flames passed, the passage was silent. The warriors on the other side also did the same, seemingly easily blocking the knife ants in the passage and bombing them to death.

After a short battle, two engineering vehicles drove in. The body tilts, pouring a large amount of mud and gravel into the passage. Finally, it is compacted with a bulldozer and then covered with a layer of sand and gravel, and the playground is restored to its original state.

Allen and the others looked at each other, it turned out that the so-called aftermath work of Cogis was so concise. In this way, there is only a large bone mound under the base, where a large number of dangerous corpses are buried. These corpses can fill the tunnels dug by the burrowing worms, and can also create obstacles for these dangerous species to infiltrate the base, without having to spend time and energy to dispose of these corpses.

It's convenient, but the thought of stepping on top of so many corpses every day doesn't feel so comfortable.

The following days were spent in a course that instilled all kinds of common knowledge on the planet of the underworld. Naturally, Ke Ges will not explain the perfect planet system to them like the mentor of Dawnblade, but directly introduce some dangerous species that Alan and others will often encounter in battle, as well as the composition and army establishment of the Sword Demon Tribe.

In addition to the knife ant and burrowing worm, another of the more common servant beasts is the wild-horned wolf. This dangerous wolf species can be domesticated into a mount, and when combined with the elite warriors of the Sword Demon Tribe, it can be transformed into a wolf knight. The Wolf Knight is the backbone of the Sword Demon Tribe, from the mid-sized tribe to the ten under the control of the Sword Demon King, all of them come and go like the wind, and most of them are in groups.

The horn of the horned wolf can fly like a bullet when needed, and once a sufficient number of horned wolves gather fire and bombard, the lethality is also terrifying. However, the horn of this giant wolf is connected to the nerves of the brain, and once the horn is shot, the nerve line must be torn off, so the horned wolf will not survive. Therefore, this kind of lose-lose tactic will not be adopted until the critical moment.

In addition, there are other powerful servant beasts among the sword demons. However, the number of these servant beasts is limited, and they are only controlled by the ten tribes, and the probability of encountering the Blood Eagle base is almost equal to zero, so Ke Jies did not mention it.

Then there is the Blade Demon, a native of the planet that dominates the Underworld Star, and the Blade Demon can be said to be an innate warrior. They are cruel and ferocious, bloodthirsty and warlike. The sword demons are not necessarily very united, even between tribes, there are constant wars.

They were humanoid aliens, tall and thin, with their hands almost hanging to the ground. The skin of the Blade Demons' bodies has a dull metallic sheen, and it turns out that their skin is almost as tough as an iron skin. The five fingers of the sword demon have hook-like sharp armor, and the front of the arm hides a retractable bone blade. The spine is exposed, with spikes, and is as hard as steel.

The social form of the Sword Demon is a relatively loose tribal civilization, taking a medium-sized tribe of 1,000 people as an example. The members of the tribe are chiefs, shamans, commanders, centurions, tribesmen, and servants. And in the ten parts, there are also archpriests, generals, and commanders. It can be seen from this that the class of the sword demon is very distinct, and the army is tightly organized, otherwise it would not be able to squeeze into the list of the seven strong clans in the Jotun Star Domain.

Cogges wasn't the kind of person who only imparted theoretical experience, and while instilling this knowledge, he even brought some living specimens for Alan and them to practice so that he could familiarize himself with the battle with the Sword Demon Tribe.

Among the servants, the burrower can be said to be the most non-threatening servant beast. Their fear of fire and low belligerence determine the fact that these dangerous species are not even cannon fodder. As for the knife ants, their individual combat power is not high. Not to mention Allen, even a soldier like Natsu can easily deal with it. But once the knife ant is formed by an order of magnitude, it is a different concept.

To deal with the servant beast of the sword ant, the army's tactics are basically long-range fire bombardment.

During this time, Corgeth even found a Blade Demon. Even though he was just an ordinary warrior of a small tribe, a seventh-level warrior like Natsu had to cooperate with the other two soldiers to kill this sword demon. Of course, for a series like Allen, it's a piece of cake. The fact that Ke Ges found another sword demon and let Eren slash him three times is a powerful proof.

As the days passed, by the time Hubble and the other squads joined the learning course, the progress of Allen's squad had left them far behind.

A month has passed in the blink of an eye, and Alan is basically familiar with life on the Underworld Star. On this day, when they were conducting a team simulation battle, there was a violent vibration in the direction of the playground. Kirges whistled and said, "It's cheaper for you, let's change the simulated battle to actual combat." ”

Natsu and the other soldiers were all overjoyed, they hadn't fought a real battle since they came to the Netherworld, and now their chance had finally come!

Two soldiers were armed with flamethrowers, while others were armed with machine guns. Alan naturally carried his fangs and led the team towards the playground. On the way, Alan said to Lucy next to him, "Don't stay too far away from me." ”

Lucy gave him a bright smile: "Don't talk about how delicate I am, but don't forget that I'm also a person who participated in the death ring." ”

In a blink of an eye, they had come to the playground, and on the big playground, four burrowing insects broke out of the ground in different directions. Eren gestured, and the team ducked over to the nearest one. After entering the firing range, Natsu and the others each looked for a battle position and used machine guns to suppress the giant insects. The two Pyros took the opportunity to push in and spew fire dragons at the Drillers.

The flames burned themselves, causing the burrower to suffer. The giant worm writhed, its tail wrapped around the flames and slapped at Natsu. The soldier changed color, and suddenly there was a flower in front of him, but it was the tall Bloy in front of him. The highlander raised an army-specific riot shield, lowered his center of gravity, and carried the blow of the Drill Worm with both shields. Bloy shook the worm's tail, and after the slap, the highlander pushed hard and pushed the tail away with his shield. Natsu took the opportunity to push in, dumping bullets from the chamber onto the Driller.

However, after the giant worm struck hard, it was already dead. It's just that Natsu and the others participated in the battle for the first time, and they were inevitably excited, but they didn't see that the bugs were dead. They didn't stop shooting until Alan shouted to stop. Eren gestured again, pointing towards the crypt passage. Bloy took the lead, shield-wielding his shield and advancing into the crypt. Alan saw it in his eyes, and thought to himself that he had to find a weapon for the highlander.

Judging from Bloy's development route, the army's steel eagle long knife is not suitable, and Bloy needs more offensive weapons like war hammers or giant axes, so I don't know if there is such a weapon in the Blood Eagle base. But that's after the battle. Alan held his fangs and spread out with Willik left and right. Lucy was in the center and a little behind, and behind them were the soldiers of the squad.

I thought that giant ants would rush up from the crypt, but suddenly a wolf howl sounded in the passage.

When he heard this wolf howl, Corgeth's face changed slightly. The next moment, a dark gray shadow leaped out of the crypt passage and landed. It was a calf-sized gray wolf with four turquoise eyes. Under the wolf's kiss, the fangs glowing with turbid yellow are all over the place. At the joints of the limbs, a pitch-black bone spur sticks out. As for the forehead of the wolf's head, there is a long Z-shaped horn.

Horned wolf!

What attracted the attention of Alan and the others was not this horned wolf, but another figure on the gray wolf.

Purple light shimmered like ice chips in his eyes, and a deep black bone blade bounced out of the flesh on each arm, and the bladed demon sitting on the horned wolf swept the crowd with a hateful gaze, and then let out a dull roar from his tall, thin body that was not commensurate with his size.

It's a wolf knight!
