Liu Yuxin and the others are at the highest point in the surrounding area, and the surrounding situation is basically visible. Even if the sound is not disturbed by any obstacles, the maximum distance that can be conveyed is only a few hundred meters. Why did neither of them find anyone around? This strange situation made the two look at each other and shake their heads, which made them shudder.

Gong Liang winked at Liu Yuxin, entered the cannon position in two steps in three steps and loaded the bullets. After Liu Yuxin got Gong Liang's instructions, she entered the carriage and activated the mecha.

“150 meters ahead of the left, underground!”

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

"Brother Liang, what should we do?"

"It seems that there is some danger. Go and explore the situation. Remember, don't be impulsive when encountering things, and come back when you find something is wrong!

"I understand, Brother Liang"

Liu Yuxin agreed, controlled her grass green camouflage mecha and jumped out of the truck, holding the electromagnetic rifle in her hand, began to search forward carefully.

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

"Brother Liang, I found the entrance! It seems to be a tunnel leading to the underground."

Gong Liang used a telescope to see Liu Yuxin who found the hole and was about to get in. He quickly made a sound to stop his recklessness:

"Liu Yuxin, don't rush in, first check if there are any traps around you!"

Depending on the situation, the opponent they are going to encounter this time is probably a group of humans. In this wilderness, the other groups of bold criminal gangs are mysterious and strange sand people. Both types of people are very good at using favorable terrain to set up deadly traps to hunt down prey that they cannot compete with.

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

After a slew of exploration around, Liu Yuxin confirmed that behind the hole in front of her was just an ordinary underground passage. Liu Yuxin no longer hesitated and drilled in with an electromagnetic rifle.

The dim sky made Liu Yuxin fall into darkness after only a few meters. He had to activate the infrared vision of the mecha and continue to walk down. The mecha's eyes shone with a red luster that made people's hearts shine.

"ah!"

Shortly after entering the cave, Liu Yuxin clearly heard another woman's scream, which made Liu Yuxin feel a little impatient and quickened her feet a little.

After walking a while, Liu Yuxin could already hear some strange tones made by unknown instruments, accompanied by waves of "hulu" human excitement howls. Liu Yuxin knew that she was about to find the source of shouting and asking for help, and her movements became more and more careful.

After walking for a while, the corridor in front suddenly broke, leaving only a broken platform that was several meters above the tunnel entrance. Liu Yuxin walked carefully to the broken platform, and noisy singing and laughter came in waves from Liu Yuxin's bottom. Liu Yuxin turned off the infrared mode of the mecha and quietly poked her 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 human clothes are simple, and many people only have some fur or woven plants around important parts, and some accessories polished by various bones on their wrists and necks. Some strong men have long strings of claws and teeth hanging on their chests, sitting on the ground watching the rest perform.

Above the burning bonfire, there was a huge soup pot. Various corpses rolled in the boiling pot. The giant wolf with broken legs was broken and the scorpion was stinged with the scorpion tail. The centipede with its head and tail removed and the poison sac was removed. Liu Yuxin even found a woman with her hair shaved from it!

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

"Da~"

The mecha faithfully reproduced Liu Yuxin's movements, and the metal fingers scratched the face, which was not very conspicuous but extremely conspicuous.

"Who!"

The sand people below immediately became alert and looked alert. Several agile leaders even started climbing directly.

Liu Yuxin screamed in her heart and turned around and ran away. He didn't think those who wanted to come up wanted to invite him to have dinner together. Besides, he couldn't have eaten such a hodgepodge...

"Brother Liang, start the vehicle quickly! Shamin, the underground caves are full of Shamin!"

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

As soon as he ran out of the tunnel, Liu Yuxin turned over and the truck that had already started. Gong Liang immediately asked the truck to speed up and prepare to take Liu Yuxin away. This is a place of failure.

The Shamen were also very fast. Before Liu Yuxin and his friends drove their trucks fifty meters away, the most agile Shamen chased after them. When they saw the truck running away, they took off the weapon they were carrying and shot randomly.

"Swish swish swish swish swish swish"

"Doduo"

...

Although these sand people were simple and had a little similar habits to the primitive tribes, their equipment was not at all behind, and even more fierce than ordinary small and medium-sized forces. There was actually a lot of military equipment in their weapons, and Liu Yuxin was beaten very embarrassed.

Liu Yuxin, who had already jumped out of the car, used her mecha body to block the various bullets flying towards the truck, and used an electromagnetic rifle to fight back. Under his precise shooting technique, Shamin kept falling to the ground and killing him, but Shamin had no intention of giving up.

"Brother Liang, my armor is almost unable to hold on! Quickly enter the ruins of the city!"

Seeing that several positions of his mecha began to float red, Liu Yuxin shouted anxiously.

In the sand sea without obstacles, it is almost impossible for them to escape from the dense pursuit fire. The only opportunity is in the abandoned old-time city ruins. Only in the complex terrain of the city can they find enough obstacles to avoid the enemy's long-range concentrated fire.

Gong Liang obviously thought of this. The front of the truck swung toward the huge city ruins. According to the map, it seemed that before it was abandoned, it was a first-class city with a depth of dozens 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 you are lucky enough, it may help them get rid of the pursuers behind them.

After being chased by the group of desperate people for nearly ten years, they successfully escaped into the ruins of the city. With the help of a well-connected transportation network, Liu Yuxin and the others successfully got rid of the sand people. Gong Liang parked the vehicle on the back of a collapsed building, and his face was lying on the steering wheel and gasping:

"We've dumped them?"

Liu Yuxin climbed to a high position, used the radar to scan it repeatedly several times before jumping down:

"We should get rid of them. There are no traces of large and medium-sized life activities found in the nearby kilometres."

After not having to cover Gong Liang's truck, Liu Yuxin, who had taken action, taught the followers a lesson. The continuous large number of casualties finally succeeded in making the sand people give up the idea of ​​putting Liu Yuxin and the others on the dining table.

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

After a few minutes of buffering, Gong Liang had already recovered. After Liu Yuxin mentioned Sha Min, he drew a cigarette:

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

"When the number of alien species increases, the alliance's armed forces begin to be stretched, the alliance's decision makers have to consider the specific operation of the city. Some areas with little value or maintenance costs are taken for granted for granted. Some people choose to stay and establish gatherings because their hometown is difficult to leave, but they underestimate the cruelty of the desert!"

"The harsh living conditions made the aliens here even more cruel and aggressive. The supply line was established from the Alliance Security Zone and then it was completely destroyed after several alien tides. The desert area completely broke away from the alliance system. In the brutal struggle against survival, those who lost supplies were eliminated from each other, and finally the strongest and smartest genes were left behind!"

"Those aliens have their own unique insights and values. You cannot measure them by their own moral standards. In fact, they have chosen another evolutionary direction and become different species from us. Even though they look and genes are the same as us, they have actually become a group of beasts with human appearance!"

After hearing this, Liu Yuxin felt a little upset. Human beings kept boasting that they had defeated nature and were the master of fate. In the old era, Liu Yuxin also agreed deeply. However, the counterattack of the earth was beyond everyone's expectations. The rapidly evolving aliens drove humans out of the seat of the overlord and began a new round of competition. Human beings who were unwilling to fail started a war for more than 100 years.

This is what Liu Yuxin learned recently!

Perhaps he is not qualified to tell the elites who formulated the entire human strategy that they were wrong, but Liu Yuxin really doesn't like this world full of disputes. The long-term war has spawned forces from all sides and cultivated aristocratic and luxurious family that does not take ordinary people seriously.

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

Liu Yuxin, who was a little unhappy, thought of going out for a walk.

Seeing that Gong Liang did not object, Liu Yuxin popped herself out of her armor and prepared to experience the scenery of this sea of ​​death with all her heart.

"Bring yourself up!"

Gong Liang threw his bp2000 to Liu Yuxin again.

Although this small energy weapon is not as good as its latest model bp3000 and cannot adjust the output power, it is no problem to deal with some common alien species.

"Brother Liang, what about you?"

Gong Liang patted the 30mm caliber cannon beside him:
Chapter completed!
