Mars has only half the radius of the Earth and a volume of only 15%, but its surface area is about the same as that of the Earth's land, and with the exception of the Moon, it is the most suitable planet in the solar system for development. After all, the temperature of several other satellites is often plus or minus hundreds of degrees, which is difficult for human survival.

Mars has been developed for decades, and there are still very few surface structures. One is that the gravity on the surface is less than half of the Earth's, which is difficult for people to adapt to, and the most important point is that the Martian atmosphere is very thin, and a random meteorite can smash a big crater in the ground. The building is placed on the ground, and it is purely a gamble of luck.

The largest human gathering point on Mars is the Mariner Canyon, which is 2,000 to 7,000 meters deep, digging deep into the canyon to form a huge underground city, which is where the McVan landed.

Walking out of the cabin, although I had been prepared, the low temperature of more than ten degrees below zero also made people feel refreshed and cold. Yun Feng had already keenly heard the sporadic gunshots in the distance, and couldn't help but be eager to try. This is Mars, it's rare to have such an opportunity.

The space illuminated by the lights as if it were day is all supported by rough metal frames, and the most important thing on Mars is all kinds of metals, so it is really a small waste. Gravity is less than half that of the Earth, and it feels a little light and fluttery when walking.

"Where does the oxygen on Mars come from? You don't even need a face mask. ”

Yun Feng asked the wolf team members who seemed to be extremely comfortable except for Nitya and Nathan. These guys often go on missions to Mars, and there is no problem of getting used to the environment.

"Mars is not short of water, and by using simulated sunlight, enough plants can be grown to achieve the oxygen and carbon dioxide cycle, which of course can only be achieved in such a confined space."

The crowbar took a cigar in his mouth and replied casually disapprehantly. He was observing the soldiers who had disembarked before them, and they had quickly divided into several teams and ran in different directions.

Yun Feng nodded clearly, it was not a profound technique, so he didn't ask any more.

The mission of the mercenaries is different from that of the army, which prioritizes ensuring that the space flight docking platform is not occupied by the rebels, and then gradually expands the scope of protection and clears the rebels. The four mercenary teams, on the other hand, are purely offensive, and of course, if the mission to rescue the hostages fails, there is an excuse to shirk. In short, everything went well, the mercenaries took the money, something went wrong, and the black pot was in charge.

It didn't take long to wait, and an officer with the rank of colonel hurriedly ran over.

"I believe you already understand the seriousness of the problem, and I don't need to say more, for the sake of the Federation, we must thoroughly let those fat pigs understand that the United States is strong and inviolable. I've asked my men to send you the specific mission to the connector, and no matter what the cost, you must achieve the mission goal! ”

Without chirping, the colonel shouted a slogan and asked their group of mercenaries to rush to the front line, and it was probably not optimistic that the situation was very unoptimistic.

"Humph!" The wolf snorted coldly, "I warned those bastards about the last Martian mission report, but it didn't work at all. I'm only sharpening my knives now, so I'm going to do something earlier. ”

"Head, don't complain, besides, such a fun task, if you really lose it with a word, it will be a real waste."

The monkey licked the corners of his mouth and went crazy excitedly as he walked, he had been lying in the hospital bed for more than two months, and his bones were going to be idle, how could he let go of such a fun task now.

Yun Feng looked around as he walked forward with the team.

The huge platform carved out countless spaces around the rock wall, planted with many plants, and separated by glass, should be the space command post that commands take-off and landing. There is only one exit from the entire platform, and the huge metal doors in the other directions are tightly closed, which should be the temporary storage of the space shuttle.

After passing through the arched passage more than 60 meters wide and 40 meters high, you will arrive at a huge and extremely open space, surrounded by green trees, and there is a green belt in the middle for separation.

"The materials that are usually used here to temporarily store and prepare for transportation back to Earth are all refined metals, and Mars has more of these things."

The wolf said casually, and had already picked up the assault rifle.

In this space of nearly 100 meters high and tens of thousands of square meters, the crisp gunfire can be clearly heard. Dozens of meters above the ground, the circular platform dug out of the brown rock wall encircling the entire space was surrounded by a number of heavily armed soldiers, and six 23mm cannons were aimed at the three entrances.

"The war is already so bad."

The brown bear lamented that this is already the last line of defense, as long as the rebels capture here, they can occupy the space platform, and if the earth wants to send another army, it can only be airborne on the surface and then attack from below the canyon.

"It's our turn. Apple! ”

The wolf snorted, and Apple immediately nodded: "Our first target is a satellite communication base station about seventy kilometers away from here. Because of the scale of this rebellion, except for the communication of the space platform, which can still be used normally, the rest of the communication base stations are all controlled by the rebels. If these base stations cannot be recaptured, the army will not be able to move outward quickly. ”

Looking at the route sent by Apple to the team channel, Yun Feng gasped. The seventy-kilometre road is almost tripled here, and there is no certainty that the route will be safe.

That's it, that's just the first goal. And the satellite communication base stations densely spread all over Mars surround the entire Mars, and anything marked with a red dot is a target that they must take.

The entrance to the left side of the square has been blocked by countless large shipping containers and dilapidated vehicles, a dozen snipers have occupied a vantage point to aim outward, and dozens of soldiers are idly hiding behind obstacles, smoking and farting, very leisurely. Only the occasional gunfire proves what is going on here.

Each of the four mercenary squads has their own goals and has dispersed. The task of the Wolf Squad is not the heaviest, but it is the most tedious, requiring countless locations, unicorns and cobras working together, and the specific mission goal is likely to storm the base camp of the rebel-controlled nuclear fusion power plant, and the hurricane should also be a satellite base station grab.

Hearing the sudden gunfire in the middle passage, the wild wolf did not dare to slack off, did not ask for fire cover, made a gesture to his team members, and took the lead to climb the obstacle blocking the passage.

Yun Feng tightened his backpack, and under the surprised gaze of the idle soldier, the two jumped out of the passage, and rushed out directly without looking for any cover.

"**, what a madman!" Several snipers cursed at the same time, but they did not dare to move, and their eyes were firmly attached to the scope. Their task was to defend, and they must not abandon their positions until there were not enough troops to arrive.

The twenty-meter-wide passage was full of bombed-out vehicles and collapsed rock walls, and the further you went outside, the darker it became. The lights had long since been cleared by the rebels, and even the lines were completely destroyed, with only the blood-stained ground and the smell of blood.

With night vision goggles, Yun Feng opened the way in front, the brown bear monkey protected the Apple Palace, and the others cautiously used the wreckage of the vehicles in the passage to cover the advance.

As the passage widens and vandalized shops appear on both sides, Apple has sent everyone a topographical map of the vicinity, reminding: "A hundred meters further on, there is the largest settlement in the vicinity." Mars is rich in metal deposits, and it is more expensive to build houses with cement, so most of the buildings are made of metal, and there are caves dug around the rock walls where people can live. I'm sure the rebels will be stationed here, Vic, be careful, even if it's an M500, the maximum range is no more than three hundred meters, the buildings here are complex, and the caves in the surrounding rock walls are the best hiding places, as long as a high-precision sniper rifle is enough to seal the entrance to this passage. The other party must have known that we had arrived, and I found three hidden motion sensors on the way. ”

Yun Feng was already scolding in his heart, there were indeed a lot of people, but they were all hiding behind the thick rock wall, both sides were fighting defensive battles, and with the support of the metal frame, even the machine guns couldn't shoot through, let alone his small pistols.

The location of all the rebels is marked on Apple's topographic map, mainly in the caves at the front of the passage, near the caves on both sides of the passage, and in some metal boxes in the middle. If he wants to kill these people completely, relying only on Yun Feng's small pistol is enough for him to break his legs.

"Hey, the maniac's ears are more accurate than the heat sensor." Crowbar sighed, "We don't have heavy weapons, there's nothing we can do with these metal boxes, head!" ”

The wild wolf knows the meaning of the crowbar, and this time it is not those stragglers in Africa that they have to face, but the veterans who have survived more than a month of fighting, and they have the advantage of numbers and terrain, and this bone is not easy to gnaw.

"Sixty-seven, seventeen on the high front, twenty-eight scattered in the flat buildings, and about ten on the rock walls on either side. Maniac, the middle hand is handed over to you, is there any certainty.? ”

Yun Feng untied his backpack and moved his shoulders, "Meaningless." The distance between the caves on both sides was at least three hundred meters, and I could only attract their attention. ”

The wolf nodded, "Nitya, cooperate with the madman to suppress the target in the front height." Quick Knife Hand, Brown Bear, Ghost Hand, you and I rush out together and suppress the fire on both sides. Shadows, monkeys, touch them from both sides with invisibility cloaks and kill them. Crowbar and Nathan are ready to support the madman, and Nightingale protects Apple. Get ready! ”

After assigning the task, Yun Feng rushed out directly, like a flickering phantom, hiding in the shadow of the building and running quickly.

The gunshots rang out from all directions continuously, but they only swept behind Yun Feng in vain, and it seemed that even the bullets couldn't catch up with his speed.

As soon as the wolf clenched his fist, the four of them rolled out of the passage at the same time, they didn't dare to be as arrogant as Yun Feng, they bowed down and ran forward quickly, and the assault rifles in their hands shot at the caves on both sides.

The crowbar pressed head-on, and Nitya finally pulled the trigger, and a blood-colored flower suddenly bloomed on the opposite cave.

Yun Feng flew up and jumped up, dodging the cross-fire of the blocked space, and the two guns came out together, and in less than a second, the four firing points had been completely dumbfired, and four people died under his gun. If it weren't for the others to hide quickly, Yun Feng would have been able to kill these people within three seconds.

The four wild wolves were divided into two groups, two by two cross-covering shots, and the fire suppressed the caves on both sides, and they were extremely skilled in cooperating.

The shadow and the monkey had put on a transparent smock, much like the cloak Harry Potter had draped, but it was magic, it was technology. The use of light refraction to give the human eye an illusion is very expensive and has many weaknesses.

Heat sensors, motion sensors and infrared sensors can all be easily detected, and if the speed of movement is too fast, it can be seen with the naked eye. It's not a new technology, after all, the finished product of the latest technology will definitely not be available to mercenaries.

The two parted from the entrance of the passage, dodging possible stray bullets as they slowly approached the terraced rock wall. It's hard to see through from a distance, but if you get closer, you can still faintly see that the light around them is unnatural when they move.

The upward stairs have long been destroyed, but fortunately, the rebels on both sides are hiding in the caves and firing from the windows or doors, and there are several high and low platforms four or five meters wide in between.

"Concentrate your firepower and take out that damn yellow-skinned monkey!"

There was a scream from the cave high in front of him, and the surrounding fire suddenly became fierce, and the bullets fired from all directions forced Yun Feng to retreat into a house.

Throwing off the jacket on his body and wearing only a short-sleeved tight T-shirt, Yun Feng silently counted the gunshots.

Mars lacks several necessary raw materials, and the opponent must have its own weapons production workshop with such strong firepower, but it is unable to produce new ammunition. Therefore, it still uses the old gunpowder technology of more than 100 years ago, and the magazine capacity is limited.

“28，29,30,31,32.” Yun Feng secretly counted in his heart, although the old-fashioned firearms and ammunition have changed due to the height of human beings on Mars and other reasons, the ammunition of ordinary firearms is generally 35 rounds.

"Crowbar!"

Yun Feng shouted violently, and the person jumped out of the window, stepped the windowsill, and jumped onto the roof of a townhouse three meters away. The man was still in the air, and the guns had fired without hesitation, and the three rebels who were huddled behind the windows fell to the ground.

The crowbar understood the meaning of Yun Feng's shout, and immediately changed the magazine and ran out of the passage, and the assault rifle desperately suppressed the fire from the high front. Nathan also resisted Barrett, replaced with concussion grenades, and shot directly at the opposite side, regardless of whether he aimed or not.

Yun Feng succeeded in one blow, and didn't dare to stay on the roof for a moment, so he rolled down, landed and rolled, and drilled into another house.

Seven have been resolved, and there are still twenty-one enemies.
