Looking at Zero Doubt's expression, Cario smiled. The instructor sat down in his chair and pointed to the chair in front of his desk, motioning for Zero to sit down. Cario laughed, "You see, Hammer of Doom's recruits aren't always recruited, after all, there aren't many recruits with an average level of three or higher. So once or twice a year, a training camp like the one you stayed in. But the rest of the time, the damn bourgeoisie didn't let Lao Tzu be idle, so he had to do the job of a task dispatcher when he had time. ”

If Valkyrie had been here, he would have been unhappy with Cario's claims. Asgard has given him the responsibility not to be a simple high-level officer, but to a first-level strategic staff officer. The Command's mission release is only a small part of his job, and Cario's main job is to be responsible for the strategic planning and scheduling of the whole of Asgard. In the headquarters, he has a very high right to speak.

Naturally, Zero is not aware of any of this. So he just nodded, and then asked, "Instructor, ...... your injuries?"

"Don't get in the way, Anji Gullit isn't qualified to kill me yet. This small injury, in fact, can heal by himself without entering the cultivation tank. Cario said very stiffly, as if he had thought of something, and waved his hand in great annoyance, as if to sweep away the topic of discussion between the two. He said: "To get back to the point, this time I asked the golden cat to call you up, because I have a task that wants to cheapen you." ”

The word cheap made Zero's nerves jump slightly, with what he knew about Cario. The so-called cheap things of the chief instructor are usually linked to the difficulty.

Cario entered a series of commands on the light keys in the corner of his desk, and the blackout curtains were automatically lowered from the office windows. The wall behind Cario also flipped out a light screen, which showed a topographic map west of the Julian Mountains. On this 5,000-kilometre-long topographic map, a band of blue light extends from Asgard in the direction of the western permafrost plateau. On this band of light, there are red and green light spots flickering.

Cario explained, "These two points of light represent the alien race that we have found so far. The light point of the green sè represents friendliness, and the red sè naturally represents hostile relations......"

There are seven red and green spots on the blue band. They were flickering when suddenly a green sè went out and turned gray.

"That's your job. Cario pointed to the gray point of light and said, "Aaron, a half-human alien race. They retain the ability to fly as birds, possess intelligence equivalent to that of adult humans, and have begun to wield simple weapons. ”

As he spoke, a diorama of a half-human bird appeared on the light screen. It has an upright humanoid body, but its arms are connected to the flesh of its side like a pterodactyl. This Aaron's model is armed with a spear and automatically makes some jab-gun movements. The movements are simple but very clean, and they are effective battlefield fighting techniques.

"This gray point of light is the village of the sub-ethnic group. The village is not large, and there are more than a hundred Aarons living there. In these friendly alien territories, we all have life monitors. Just a few days ago, a life monitor set up in an Aaronic village showed that all life in the village had been lost. Not an invasion, but an extinction, without any life reaction. "The command has issued a series of orders for this, including investigating the cause of the Aaronic death and annihilating them if a foreign enemy invades. This order was to be sent out in the morning, but I saw that you were back, so I asked you to carry it out. This is a D1-level mission, and if it weren't for me, I wouldn't be able to accept this mission according to your team's rating. ”

The command graded the mission according to its difficulty, from low to high, it was E, D, C, B, A, and S. Each level is divided into three levels from 1 to 3. With the zero team only having an E level, it is natural that he can't accept D-level tasks, so he directly throws the unreleased tasks to Zero, and Cario can be said to have taken great care of him.

Zero Nature has no reason to refuse.

"Go ahead and finish it beautifully. Then, invite me to dinner!" Kario smiled.

Zero nodded in agreement and left. After he left, Cario's smile faded away, and even became a little solemn.

The reason for the extinction of the Aaronic race was not simple, and these half-bird-man adult individuals possessed the ability of liliang and agility equivalent to the third order of human ability. Coupled with the simple and practical stabbing skills, it is not a pleasure to be caught in close quarters by them. It's not hard to kill one or two half-birdmen, but it's not easy to kill the entire Aaron.

The reason why the command issued this mission was to find out whether the cause of the extinction of the Aaronic race was disease, or was it a conflict of species, or was it deliberate? If the first two are fine, if the latter is the latter, then Asgard must consider updating the surveillance model and strengthening the monitoring liliang.

Thinking about this question, Cario naturally remembered what was happening at the Cossack military base. After he and Valkyrie woke up, they immediately reported to Ben that the command's order issuance system had been used. Ben naturally attached importance to this matter, and asked the two to investigate the matter secretly. But to this day, the two still have no clue.

The people behind the scenes are clever and clean, and they can't find any relevant clues at all. Cario was well aware that the investigation should not be completed anytime soon. The Chief Instructor was not a patient man, so Cario had already given Valkyrie full authority to handle the job.

He turned his head to look at the virtual sky outside the window, and his mood was very complicated. Beneath the surface of peace, Cario felt a strong sense of unease. Unease is like an undercurrent, surging against the reef of peace in Asgard.

When Cario was sick and worried about the safety of Asgard, the city of God, Zero, who had always only wanted to make money, had already called Shangfeng and a few people to drive the same rented off-road vehicle and hit the road. Along the main road that runs north and south until the Asgard, passing through the long, dimly lit passage, when the hydraulic gate was opened, the two sides of the mountain wall used for disguise were divided equally, and a shijie of ice and snow appeared in the eyes of the four of them.

The front tailgate of the super wild car was removed, and the snow detrainer was already installed because it had to walk in the snow. The snow drain is a peripheral component of the car, which is in the shape of a rectangular steel trough. There is a slit in the front of the steel trough with a strong suction device installed in the slot, which creates a great suction force on the space in front of it. The snowdrift in front of the car is pumped into a steel trough, where it is ground into powder by thousands of steel wheels, and finally ejected by the hole-shaped snow drainers on both sides.

As thick white smoke erupted from each end of the car, the car drove forward at a constant speed of 40 kilometers per hour, gradually driving into the snow-covered western wilderness. The speed of the off-road vehicle is not fast, but it is rare in an environment where snowdrifts are piled up to three meters high. Today's weather is not bad, there is no wind or snow, and the reddish sky light reflects the magnificent sè color at the moment when the clouds are covered with ice crystals.

Yan sè is very magical, but it is a pity that it is difficult for people nowadays to be in the mood to appreciate it. It's not easy to live, and it's hard to be in the mood to see the scenery.

The car, as indicated on the electronic map, drove past the perimeter of the Cossack military base. The land seemed to have been plowed all over again, revealing bare formations that even the wind and snow had not had time to bury them all. From a distance, nearly half of the buildings on the surface of the base are in a state of destruction, and it is not difficult to see the fierceness of the battle from the other side. However, it is less than a month away, but it makes people feel far away.

Continuing westward, there is an endless stretch of tundra. A flat river, there are raised things from time to time, and they become the things of old trees that have been frozen into frost pillars. Life is rare in the tundra, with the occasional Fenri wolf scurrying by. This kind of demon wolf jǐng is extremely strong, and when the car is still at least three hundred meters away from them, it has already spotted zero of these uninvited guests. Their green and golden-threaded pupils glanced at the buggy, then let go of their hooves and swept away, quickly leaving the sight of Zero and others.

Seeing this scene, Kaede was so embarrassed that he had to get into the sniper rifle he borrowed from Zero. He was going to kill these demon wolves, after all, the fur of the Fenri wolf was very popular with the nobles. The fur could be made into a fur coat or a fur collar to adorn the coat to show off their aristocratic atmosphere. A complete fur is worth at least 300 points when converted into a success medal!

So, under the voice of Kaede's remorse, the journey turned from the plains into the frosty forest. The dense forest of conifers covers an area of tens of thousands of square kilometers and has become a natural barrier to isolate human civilization. There are dozens, if not hundreds, of indescribable alien intelligent life forms inhabiting this dense forest and the land behind it. And the expeditionary force sent by Asgard, the journey of the Golden Tomahawk was only through the frosty forest, and reached the Screaming Canyon three hundred kilometers behind.

Frosty Forest, these conifer members are much taller and taller than their counterparts from the old days. They usually require ten people to hug together and reach a height of more than 300 meters. What's more, it is nearly 500 meters tall. In this way, the giant tree is covered with long needle-like leaves, and the leaves are fat and thick, and the energy of the giant tree is stored without losing too quickly. When winter comes, these needles become the indispensable food for life in this forest.

Thick needles contain plenty of water and hungry plant fibers. Although each conifer is covered in frost, the thick bark insulates the icy cold of frost and snow, preserving the abundant nutrients in the leaves.

When the off-road vehicle drove into this forest, Zero felt like he had entered the land of giants. The tall trees are like pillars that support heaven and earth, showing a strange shijie in the eyes of a few people. Although it is a cold winter, there are still traces of life in the forest. The most common is an alien creature the size of a fox, but looks like a wolf.

These mutants, known as fox wolves, have two large, fluffy tails, which allow them to glide through the air for short periods of time. Fox wolves feed on needles, and when they eat this food, a special organ in their body digests some of the food and turns it into a poisonous gas. When needed, fox wolves emit poisonous gases like skunks, and the poisonous gases they release will not spread with the wind, but will permeate a certain area for a long time, and defend against the attacks of other mutant beasts.

In addition to the fox wolf, there are several other alien creatures active. They chase in front of giant trees, snatching food, or even tearing them apart to fight for their territory. But no matter what they're doing, as soon as they hear the sound of the buggy's engine, they'll scatter and flee, leaving Zero with nothing but a look at the strange figure.

The village of the Aaron tribe is in the dense forest, and it is not easy to find this half-birdman village in the middle of a sea of trees, as if there is no electronic map. A few people were also wandering around in the dense forest before Zuihou found the location of the Aaronic village. It is clear that a cleared land has been cleared by deforestation and has become a village for the Aaronic people. From a distance, there are patches of thatched huts in the open space, very simple construction methods, and the materials of the houses are also made of local materials. This half-birdman village allows a few people to experience the original style.

According to Asgard records, the Aaronic society is currently equivalent to the primitive age of humanity. They were matriarchal societies, and matrilineal Aarons took the position of chiefs in the village. The male Aarons were responsible for hunting, construction, and all the other heavy lifting. In the records, not only the Aaronic race, but also other intelligent races have a longer reproductive cycle than the mutant beasts, which is closer to the reproductive cycle of humans in the old era.

However, during the long period of childbearing, the offspring born still die at a very high rate. Otherwise, humanity would not have been able to defend the entire circle of civilization that dominates the coastline. From the emergence of the first generation of the Aaronic tribe to the present, it has gone through three generations of breeding, but their population has only grown from more than 20 people at the beginning to about 100 people now. But even so, the Aarons are already the most populous race among the recorded alien races in Asgard.

The buggy stopped at the entrance to the Aaronic village, saying that it was an entrance, but it was just a wooden tree as a sign. There are three skulls nailed to the wooden tree, and from the appearance, they are humans, fox wolves, and a relatively rare mutant beast, the megalodon bear. Obviously, this wooden tsubaki is both a sign of the village and a kind of jǐng notice. It's just that judging from the current situation, this kind of jǐng sue is not very useful.

Half of the huts in the village were burned to ashes, leaving only charred black marks. In the open space of the village, there were even scorch marks left by the fire, and the fire was so fierce that it burned the ground into glass. Seeing this scene, the four of them frowned. For a natural flame to reach the high temperature that bakes the ground into glass, it requires a sealed environment to be continuously warmed. The village is ventilated on all sides, and the air flow is very obvious, which is obviously not possible to meet the conditions of high temperatures.

Then the rest may be done by the capable people of the elemental domain. Using some of the abilities of the Elemental Domain, it is indeed possible to produce high-temperature energy destruction in an open environment. And the high-temperature energy that can crystallize the ground, that is at least a fifth-order liliang. A fifth-order elemental domain capable is a formidable opponent no matter what type of elemental destruction he is proficient in.

So several people immediately entered a state of imminent battle, Zero's Browning ****, Su's alloy heavy sword, and Feng's Tang knife were all in hand. Only Ma Pei had his hands empty, but the veins under his skin were bulging up so that he could transform into an ironclad rhinoceros at any time.

The village is quiet, eerily quiet. The strange source was that there were no corpses, and a few people searched the village back and forth several times, but did not find a single Aaronic corpse. The valuable object found was only a life sensor that turned into a piece of black charcoal, and judging from the traces of destruction, it was also damaged by a high heat attack.

The absence of corpses is not a normal thing, although there are very few scavenging beasts like corpse wolves in the Frosty Forest. But now it's the cold winter season, and the corpse can stay fresh for a long time. Fresh meat is the favorite of many mutant beasts, especially intelligent lifeforms like Aaron, whose flesh and blood are tantamount to a tonic existence for other mutant beasts.

But even if they were visited by these beasts, it was impossible for the entire village not to even see the shadow of the corpse, and the mutant beasts with low intelligence could not make such clean hands and feet.

"Keep looking. Zero said lightly and gave this simple order.

However, this time, the four of them turned over almost all the corners of the village, leaving no trace behind. But whether they wanted to accept it or not, there was nothing suspicious about the village except for the traces of damage. It wasn't until the four of them extended the range to within 500 meters of the village that they found the trail of battle in the east.

It was a forest nearly 500 meters away from the village, and the corpses of the sub-tribe could occasionally be seen on the nearby giant trees. The ground and several tree trunks showed large scorch marks, and among them, there were even a few scorched corpses. In front of a giant tree, a ten-meter-old wooden spear was inserted diagonally. The unusually sharp spear pierced the ground, and one of the spears had a fragment of leather deep under the tip.

The leather is dark red sè with jagged edges and signs of tearing. It is conceivable that the Aarons must have attacked those who had destroyed their village in a cluster of throwing spears. But it's a pity that so many spears only tore off a piece of the other party's robe. Zero removed the piece of leather from under the gun, and found a metal coil in the middle of it. This is a defensive interlayer, and the metal coil not only plays the role of blocking the attack, but also plays a buffering effect because it has a certain bullet effect.

This alloy coil acts as a defensive layer for clothing, which is expensive, at least not for everyone. It can be seen that this person who attacked the Aaronic tribe has some origins.

The traces of the battle were here, and they went nearly a kilometer or so deep into the dense forest in the southeast. Along the way, a few more Aaronic corpses were found. Some of them have severe burns, while others have been eaten by wild beasts. But these bodies add up to less than half a body, and at least thirty or so bodies are missing. And at the edge of the battlefield, there are some irregular traces that extend towards a downhill point, which looks like the murderer dragged the body in that direction.

So a few people followed the trail and stepped forward, and the terrain gradually descended, forming a small curve. There is a vertical stone wall with a drop of 10 meters at the bend of the slope, and there is a trench 100 meters long and about 10 meters wide under the stone wall. The trench was like a scar on the ground, and on the other side of the ditch, a black cavern appeared. The drag marks that appear from the uphill slope also appear in the trench and extend into the cave on the other side.

The entrance to the cave was pitch black, as if a giant beast had opened its mouth, waiting for its prey to come to the door!
