Liu Yuxin's position is the highest point of the surrounding area, the situation in the vicinity is basically unobstructed, and even if the sound is not disturbed by any obstacles, the maximum distance that can be conveyed is only a few hundred meters, why didn't either of them find anyone around? This strange situation caused the two to look at each other and shake their heads, which made both of them shudder.

Gong Liang glanced at Liu Yuxin, entered the cannon position in three steps and two steps and loaded the bullet, and Liu Yuxin got Gong Liang's signal, got into the carriage and activated the mecha.

"150 meters ahead on the left, underground!"

After the mecha's biological detection radar was turned on, Liu Yuxin finally figured out where the sound came from, and a bunch of dense yellow dots appeared not far in front of the mecha's tactical map.

"Brother Liang, what should we do?"

"It looks like there's some kind of danger, you go and find out. Remember, don't be impulsive, and if you notice something wrong, go back!

"Understood, Brother Liang"

Liu Yuxin agreed, controlled her grass-green camouflage mecha and jumped out of the truck, holding an electromagnetic rifle and began to search cautiously ahead.

After searching for a range of about 200 meters, Gong Liang's communicator heard Liu Yuxin's inquiry:

"Brother Liang, I've found the entrance! It's like a tunnel leading underground. ”

Gong Liang used a telescope to see that Liu Yuxin, who had found the entrance to the cave, was about to get in, and hurriedly stopped his recklessness:

"Liu Yuxin, don't rush in, let's see if there are any traps around!"

Depending on the situation, the opponent they will encounter this time is likely to be a group of humans, and in this kind of wilderness, in addition to the daring criminal gangs, the mysterious and strange sandmen, both of whom are very good at taking advantage of the favorable terrain to set deadly traps to hunt some prey that they cannot match.

In the narrow tunnels and closed underground passages, the performance of the mecha will be greatly restricted, except that the armor is still strong, and it is not enough to be used as a barrier to ensure its own safety.

After exploring the surrounding area for a while, Liu Yuxin determined that behind the hole in front of him, it was just an ordinary underground passage, Liu Yuxin no longer hesitated, and drilled into it with an electromagnetic rifle.

The dim sky made Liu Yuxin only advance a few meters before falling into darkness, he had to activate the mecha's infrared vision to continue walking, the mecha's eyes shone with a heart-chilling red luster.

"Ahh

Not long after entering the cave, Liu Yuxin clearly heard another woman's scream, which made Liu Yuxin's heart a little impatient, and her feet sped up a little.

After walking a little further, Liu Yuxin could already hear the strange timbre of some unknown musical instruments, accompanied by bursts of "purring" human excited howls, Liu Yuxin knew that she was about to find the source of the shouts and calls for help, and her movements became more and more careful.

After walking a little further, the road in front of Huo Ran was interrupted, leaving only a broken platform protruding a few meters from the mouth of the tunnel. Liu Yuxin cautiously walked to the broken platform, noisy singing and laughter came from Liu Yuxin's lower front for a while, Liu Yuxin turned off the infrared mode of the mecha and quietly poked his head out, more than ten feet below his platform, a group of bronze-skinned men and women were singing and dancing around a bonfire.

These humans were poorly dressed, many of them had only some fur or woven plants around important parts, some wrists and necks were somewhat polished with various bones, and some of the strong men had long strings of claws and teeth hanging from their chests, and they were sitting on the ground watching the rest of the people perform.

On top of the blazing bonfire, there was a huge soup pot, and all kinds of corpses were tumbling in the boiling pot, the giant wolf with broken legs, the scorpion tail stinging sand scorpion with the scorpion tail broken, the centipede with the head and tail removed, and the poisonous sac was removed, Liu Yuxin even found a ** woman with shaved hair from inside!

Thinking of the miserable and rapid scream just now, Liu Yuxin felt a tumultuous stomach in her abdomen, and subconsciously covered her mouth with her hand.

"Da~"

The mecha faithfully reproduced Liu Yuxin's movements, and the metal fingers scratched the face with a small but unusually conspicuous noise.

"What people!"

The sandfolk below immediately became alert, and their faces showed vigilance, and several leaders who were agile began to climb directly.

Liu Yuxin secretly screamed in his heart and turned around and ran, he didn't think that those who wanted to come up wanted to invite him to dinner, besides, he couldn't eat such a hodgepodge......

"Brother Liang, start the vehicle quickly! Sand people, the underground caverns are full of sand people! ”

Liu Yuxin, who was running, did not forget to remind Gong Liang, who was still watching the wind above.

As soon as he ran out of the tunnel, Liu Yuxin turned over the truck that had already started, and Gong Liang immediately accelerated the truck and prepared to take Liu Yuxin out of this place.

The movements of those sand people were also very fast, and Liu Yuxin and their truck had not yet driven fifty meters, and the most athletic sand people chased them out. When he saw the fleeing truck, he took off the weapon he was carrying and shot indiscriminately.

"Woohoo"

"Dododo"

……

Don't look at the simple clothes of these sandfolk and their habits are somewhat similar to those of primitive tribes, but their equipment. But it is not backward at all, even more ferocious than the firepower of ordinary small and medium-sized forces, and there is actually a lot of military equipment in the weapon, Liu Yuxin was very embarrassed for a while.

Liu Yuxin, who had already jumped out of the car, used the body of the mecha to block all kinds of bullets flying towards the truck, and at the same time used an electromagnetic rifle to return fire.

"Brother Liang, my armor is almost out of place! Fast forward to the ruins of the city! ”

Seeing that several positions of his mecha began to turn red, Liu Yuxin shouted eagerly.

In the sea of sand with no obstacles, it is almost impossible for them to retreat in the dense pursuit fire, and the only chance is in the abandoned ruins of the old city, and only in the ruins of the city with complex terrain can they find enough obstacles to avoid the enemy's long-range fire.

Gong Liang obviously thought of this, and the front of the truck swung towards the huge ruins of the city, according to the map, it seemed that before it was abandoned, it was a first-class city, with a depth of tens of kilometers and a population of millions, because the city itself has a large number of industries, its transportation system is also very convenient and developed, if they are lucky enough, they may be able to get rid of the pursuers behind them.

After being pursued by the group of outlaws for almost ten years, they successfully escaped into the ruins of the city, with the help of the extensive transportation network, Liu Yuxin and they successfully got rid of those sand people, Gong Liang parked the vehicle on the back of a collapsed building, lying on the steering wheel with his face panting:

"Did we get rid of them?"

Liu Yuxin climbed to a high position, and jumped down after scanning it several times with the radar:

"It is time to get rid of them, no traces of large or medium-sized life activities have been found in the vicinity for several kilometers"

After not covering for Gong Liang's truck, Liu Yuxin, who was free, taught the trackers a hard lesson, and the continuous large number of casualties finally succeeded in making those sand people give up the idea of putting Liu Yuxin and them on the table.

"Brother Liang, who is Shamin? Why did they become like that? ”

After a few minutes of buffering, Gong Liang had already eased his spirits, and when he heard Liu Yuxin mention Shamin, he smoked a cigarette:

"Those sand people are actually the descendants of the people of the city in front of them......

"When the number of xenomorphs grows, the Alliance's armed forces begin to be overstretched, the Alliance's decision-makers have to consider the specific operation of which city to protect, and some areas that are not of much value or too expensive to maintain are naturally abandoned, and some people choose to stay and establish a settlement because they can't leave their homeland, but they underestimate the cruelty of the desert!"

"The harsh living conditions have made the xenos here even more ferocious and aggressive, and the supply lines established here from the Alliance's safe zone have been completely destroyed after several xenomorph waves, and the desert region has completely broken away from the Alliance's system. In the brutal struggle for survival, those who have lost their supplies eliminate each other, leaving behind the strongest and smartest genes! ”

"Those aliens have their own unique opinions and values, and you can't measure them by your own moral standards, in fact they have chosen a different evolutionary direction and become a different species than us. Even though they are physically and genetically identical to us, they have become a bunch of beasts with human appearance! ”

Liu Yuxin's heart was a little breathless after hearing this, human beings have been boasting that they have defeated nature and are the masters of fate. In the old era, Liu Yuxin also thought so. However, the Earth had to fight back, and to everyone's surprise, the rapidly evolving xenos ousted humanity from the overlord seat and began a new round of competition. Unwilling to be defeated, mankind has therefore set off a war that has lasted for more than 100 years.

This is what Liu Yuxin has learned recently!

Maybe he is not qualified to say that they are wrong to the elites who formulate the grand strategy of the entire human race, but Liu Yuxin really doesn't like this world full of strife. The long-term war has given birth to the forces of all sides, and has cultivated a family that is arrogant and extravagant, and does not take ordinary people seriously.

"Brother Liang, you rest first, and then I'll go around and see if there is any potential danger."

Liu Yuxin, who was a little unhappy in her heart, thought of going outside for a walk.

Seeing that Gong Liang did not object, Liu Yuxin ejected herself from the armor, ready to experience the scenery of this sea of death.

"Bring yourself on defense!"

Gong Liang threw his BP2000 to Liu Yuxin again.

Although this small energy weapon is not as good as its latest model, the BP3000, and cannot adjust the amount of output power, it is completely easy to deal with some common xenomorphs.

"Brother Liang, what about you?"

Gong Liang patted the 30mm caliber cannon beside him:

"Don't I have it? Don't worry, there are no high-level energy reactions around here, as long as you keep the radar on the mecha on, there will be no huge changes here. ”
