In the area filled with red fog, the field of vision is extremely narrow, even if it is a flat place, looking around, with the eyes of the engine soldiers, you can see things within a radius of two hundred meters at most.

In addition, the terrain of Mars is extremely complex, so the actions of the Fifth Army must be based on full reconnaissance and counter-reconnaissance.

Although they are more familiar with the action in the red mist, with thousands of years of rich experience in war reconnaissance of human beings, it did not take long for them to gradually become familiar with the actions in the red mist, at least in reconnaissance and counter-reconnaissance, not only is it not weaker than the other party, but also gradually exerts the rich combat experience of human beings, often making the alien race jump, sweeping but returning empty-handed.

At this moment, a few scattered but well-trained figures climbed over the small hill shrouded in red mist, and saw their limbs flying sideways, green blood splashing all over the ground, a mess.

"My God, are the people of the Fifth Legion so violent?" Zhao Gu exclaimed.

"Don't sigh, hurry up and bury the sensor, Zorn, help me get one." On the side, Cheng Yi said.

Casually brushing aside the corpse of the thorn demon whose head was crushed into a broken watermelon, Cheng Yi shook his head, it must have been the big captain of the fourth detachment, he liked to grab the head of the alien race and crush the head with the red crystals inside.

"Come on, come on, know that you are calling this genius." Zorn muttered, took out a brown sphere the size of a ping-pong ball from his backpack, and handed it to Cheng Yi.

"Okay, you're a genius, but you're no more genius than Ling An, right? People don't talk as much as you do. A little farther away, Zhao Gu, who was pouring some liquid on the corpse of the alien race, teased.

The liquid is colorless, but as soon as it touches the corpse of the alien race, it produces a violent reaction, and the corpse of the alien race, which is already decorating at an extremely fast speed, is now dissipated at a speed visible to the naked eye.

Zizi Zizi~

"This thing is really scary, I said, can you turn it by splashing this corpse water directly on the alien race?" Zhao Gu was amazed.

"Living aliens, with their physical resilience, can resist this erosion, not to mention them, even if they are splashed on you, they can't die, don't you believe in trying?" Cheng Yi just buried the sensor and clapped his hands.

"Let's go, Captain Matt and Ling An are waiting in front."

Until now, Cheng Yi still feels a little incredible.

Nothing else, just think it's too coincidental.

A month ago, they volunteered to join the Fifth Legion as part of the Owl Squad.

The problem is that the comrades-in-arms who formed a new detachment with them are actually new fighters!

Among the personnel that [Owl] added when he came back last time, all the newly promoted C-level personnel were divided into three-tier teams.

The third team was all killed in the last battle behind enemy lines, so the entire third team, including the team leader, was full of fucking recruits!

What made Cheng Yi even more speechless were these new comrades-in-arms.

The captain of the detachment is a guy named Matt, although he is B-level, but looking at his appearance, he is not young, he should be limited by talent like himself, and he has been relying on diligent cultivation to break through to B-level.

As for the team members......

Zhao Gu followed him into the Fifth Legion, and then the two boys who had been promoted together in the promotion hall at the beginning, one was called Zorn and the other was Ling An.

There is another one, who is not younger than himself and Zhao Gu, called Kaisen.

The total number of each squad of the Fifth Legion is not large, and there are only seventy-eight people in the [Owl] team, and there are only these six people in their three teams.

It's not that Captain [Owl] Jiang Muye is biased, but the average number of people in each squad is seven.

However, although there are few people, all of them are elite, and each squad has a B-level fighter as a captain, and the team members are all C-level, and even a few of them were originally captains of the guerrilla squad.

After a long time in the rear battlefield, the combat effectiveness of the Fifth Army is incomparable to that of normal guerrillas, take the corpses that were disposed of by Cheng Yi and Zhao Gu before, there are more than 20 alien races, including assassins, raiders, and a kind of minotaur that was rarely seen before, in just one minute, it was killed by a team of only seven people, and even the news could not be transmitted.

While thinking, Cheng Yi, together with Zorn and Zhao Gu, quickly climbed over the small hill and chased forward, leaving only the rapidly decomposing alien corpses in this low-lying area.

After a while, a young man with a gun and an eyepatch appeared in his field of vision.

"Ling An, it's all dealt with." Cheng Yi said.

"Well, I'm fine here, too." Ling An nodded, "Captain Matt sent a message ordering us to move closer to the center of the formation and protect the core mecha. Let's go, front ...... Old. ”

The corners of his mouth twitched slightly, Ling An was still not used to it, he was a polite person.

But Cheng Yi said that the seniors were shouting, just like how old he was, so Ling An directly called the old man good.

"Where's Kayson?" Zorn scanned around, but didn't notice the yellow-haired fellow man.

"He's in front, go to Captain Matt, you know, the one hundred and fifty meter limit distance rule." Ling An shrugged his shoulders and pointed behind him, in the red mist, there was a faint very small figure, that was Kaisen.

There are several rules that must be observed when operating in areas of red fog behind enemy lines, where the terrain is complex and where the field of vision is narrow.

One of them, the 150-metre limit distance rule, is used to maintain contact between the members of the reconnaissance unit when conducting a search formation.

This distance is the maximum distance required by each member of a detachment between each team, not that this distance can ensure that when someone is attacked, others can find and support at the first time, but this distance can have a variety of ways to transmit warning messages when they are suddenly attacked, so as to expand the search range while saving the lives of the team members to the greatest extent.

Now that the central command system has issued an order to assemble and shrink the formation, this distance will naturally be reduced.

Ling An and the others walked towards the center of the [Owl] team's formation, as if a thorn demon would scream out of the red mist at any moment, or a raider would emerge from behind him, spreading his flickering scythe forelimbs.

Although he had been joining the Fifth Legion [Owl] squad for a month, this was the first time that Ling An had come to the rear battlefield with the squad.

The day before yesterday, they had just entered the Red Mist Zone through a secret passage, on the southern edge of the Tarsis Plateau on Mars.

This place is full of dangers, and it is not at all as desolate as Ling An has seen in film and television works, but because of the red fog, it has an extremely strange atmosphere.

Red fog has changed the ecology of Mars.

For example, at this moment, when Ling An's figure was rapidly passing by, several bushes with unusually bright red fruits and dark blue blades of grass were swaying slightly by the strong wind.

This is called the blood fruit shrub, although the name is a little scary, but surprisingly, this is a plant with medicinal value, the blood fruit on it, after slightly processing, can be used as a hemostatic agent, direct consumption also has an analgesic effect.

There is also the soil in the Red Mist area, which is also full of a nutrient, but the plants in the Red Mist area, including the Red Mist itself, have a property.

Staying in the red mist area for a long time, or eating too much of the plants raised by the red mist, will make people haunted by abnormal excitement, inhibition and other effects, a series of neurological and psychiatric symptoms, and even affect the growth of mental power!

And this time is about three months, so when there is no emergency, each squad of the Fifth Army will return within forty-five days of entering the Red Mist Zone, and will only enter the Red Mist Zone again after at least half a month of recuperation.

The red mist can be sucked, and it also contains a relatively rich amount of energy, which is also one of the reasons why the strength of the soldiers of the Fifth Legion has improved relatively quickly, and there is even a relatively rich oxygen in it, but it will be a little strange to inhale at first.

In fact, for these fighters who can rely on the engine to decompose G matter to provide the energy required by the body, they no longer particularly rely on the body's oxygen consumption to provide energy, but breathing has become a habit.

Soon, Ling An and the others had reached the designated position, and Captain Matt and another team member, Kaisen, had reached the designated position.

"Captain, we've arrived, and we've left enough detectors along the way." Cheng Yi said.

Ma Ting nodded, his eyes glancing at Ling An.

Ling An didn't expect at first that Lin Cheng's so-called arrangement was to let Matt also enter the Fifth Legion and become his captain again.

Matt had been suppressing himself before without breaking through, and this breakthrough, the speed at which he upgraded was very amazing.

More than a month has passed, and his combat power has skyrocketed at a rate of tens per day, and at present, it has stabilized at two thousand one.

This combat power may be ranked very low among all the detachment leaders of [Owl], but Matt also has the strength of a mountain, which is also an ability that several other detachment leaders, including the captain Jiang Muye, who is an A-rank fighter, also have an ability.

But Ling An always had a grudge against Matt, that is, why he didn't choose to break through at the beginning, in that case, Sun Lei, Zhao Bin and others would not die.

"It's all there." Matt said lightly.

"The task of our third team is to protect the right flank of the center, to prevent any alien race from being detected by the fourth and fifth detachments, now, each of them keeps a distance of thirty meters, remember, if you see a foreign race, kill it directly."

"Yes!"

At the sound of an order, everyone, including Ling An, dispersed, with Matt in the center of them, once an enemy appeared, as long as the various team members could resist for a while, he could arrive.

At this time, Ling An's personal terminal came with instructions.

The order from the [Owl] central command system showed that the units had arrived at the designated position, the formation change was completed, and they continued to move forward.

Ling An took a deep breath, but he was almost choked by the red mist, he held back his cough and turned his head slightly to the left, and saw several tall shadows that were faintly visible two hundred meters away.

Ling An knew that it was a special mecha of the [Owl] team.

Rushing behind enemy lines is not the same size as the guerrilla squads in the past, and four special mechs that are seven meters high and covered with a camouflage layer can provide sufficient mobility, fire support, and logistical support, and can easily shuttle between complex terrains, and can maintain stable communication within a certain range.

These mechs, along with a small squad of members guarding them, form the command center of the entire [Owl] squad.

Once these special mechs are destroyed, the [Owl] team will be blinded by stabbing eyes, smashed brains, and can only escape back into the range of human control.
