The distance is closer, and Ye Xun can better capture the traces of wind and earth chisels under this mottled wall.

The huge and mottled wall, like a long winding dragon, stretches for two or three kilometers in length, as if it was a fortress used by ancient humans to defend against foreign invasions.

Behind the fort, a large number of primitive buildings are presented side by side, standing with their backs to each other, and even rows of wide loess roads appear.

The whole site is empty, only the cold wind is bleak, blowing on the building, creating a "whirring" wind sound, like a bamboo flute, poignant and graceful.

Ye Xun came to the foot of a city wall, looked at the ancient building that had long been dilapidated, tentatively reached over and gently pushed against the building.

In an instant, the seemingly solid rock suddenly weathered into a pile of gravel, escaping from between the fingers, forming a line of sand.

Ye Xun twisted his eyebrows into a Sichuan character and whispered, "In ancient times, people did not have smelting technology, and the hardest object they could touch was stone, so they usually chose this kind of round stone to build shelters. ”

But even such a hard rock can't stop the erosion of time, and it has weathered to such a field.

It is enough to show that this ancient tribe has existed for a long time, and I am afraid that it will be measured in 10,000 years.

Wang Gang also walked up and looked at the weathered buildings around him with a puzzled face, "I've read in the book that the ancients usually lived in clans, and such a large clan group has at least tens of thousands of people, what is the reason why they disappeared later and became completely extinct?" ”

Ye Xun shook his head, when he was in school, his historical grades had always been bad, and he really couldn't deduce the reason for the disappearance of these ancient civilizations.

Subsequently, when they were close to the complex, they found a lot of stone pillars.

Some of the pillars have collapsed into piles of powder, while others still have a broken appearance, standing there tenaciously.

I don't know how many years of wind and rain have passed, the surface of the stone pillar has long been mottled, and it has been corroded by the rain to create a series of anti-honeycomb eye-like scars, through some of the reliefs remaining on it, Ye Xun still vaguely guessed that the building here seems to have a certain relationship with the "three-eyed man".

Unfortunately, it was late at this time, and everyone had no time to study the contents of these reliefs, so they had to find a few fairly solid stone walls, and leaned against them to raise a bonfire.

After searching for days, everyone's physical strength was consumed, and after sitting down, Ye Xun felt sleepy for a while, so he simply arranged the personnel for the night vigil, and then leaned against a stone, closed his eyes and fell asleep.

As the main combat force of the team, Ye Xun must ensure that his physical condition is at the peak at any time as much as possible, so as to meet the challenges that may be faced at any time.

But this sleep was not sound, not long after Ye Xun closed his eyes, there was a "whirring" wind in his ears, and hidden under the wind was some ethereal and weird slight crying.

It was like a ghost's cry, so terrible and sharp that he was distracted, and he opened his eyes again after a while.

When he woke up again, it was already the second half of the night, Ye Xun got up, felt the strange cold wind lingering in his ears, and his heart became more and more calm.

Not only him, but even Wang Gang, Wen Qing and others, who were sleeping not far away, also opened their eyes at this time, revealing the same puzzled eyes as Ye Xun.

Obviously, everyone heard the kind of "crying" mixed with the bleak night wind, and the resentment was tactful, as if the female ghost was crying, and the weird and cold feeling set off the atmosphere to the extreme.

Wang Gang couldn't help but start to get nervous, looked around with his probe, and leaned towards Ye Xun, "Ye Xun, there won't really be ghosts in this place, right?" ”

"You're such a big person, and you don't do anything wrong, are you afraid of ghosts?"

Ye Xun smiled dumbly and couldn't help but glare at him.

At this time, Gao Yang came over with a box similar to a radio, and frowned, "I don't know if there are ghosts here, but I'm sure that there must be a very special magnetic field around here, you ...... listen."

Then, he handed over the radio station, and everyone listened attentively, and sure enough, they immediately captured a large number of "zizi" electric current sounds, as if the signal had been interfered with by some kind of strong magnetism, and became inexplicably hoarse and weird.

Ye Xun frowned again, "It seems that the reason why our military radio station failed was because of this strong magnetic interference, I believe that as long as we find the source of this magnetic field, we should be able to accept signals from the outside." ”

Military radios have a wide range of signal coverage and use satellite systems.

However, there is no satellite signal in this canyon, which means that there must be a strong magnetic interference signal in the middle of the canyon, maybe it is that thing that affects everyone's brain waves, causing them to be unable to walk out of this canyon.

Thinking of this, Ye Xun looked around, and then said to Yang Yong and the others who came over, "In this way, let the people of the special combat team continue to rest, and we will take out a few people who are relatively fast, and go to the direction where this kind of wind comes from to take a look, maybe there will be a harvest." ”

"Okay, then you must come back safely."

Yang Yong took his own gun and said worriedly.

Although he is the elite of the field team, due to his talent, he cannot awaken the bloodline of the mutant, so he is only an ordinary person with special training in terms of ability, and he can't keep up with Ye Xun's rhythm, so he can only be forced to stay where he is and continue to lead his special combat team members to patrol around.

Ye Xun and the others traveled lightly, relying on the strong magnetic signal captured by the radio, and left the wall directly, and walked towards the depths of Pinggu.

Hundreds of meters ahead, a strange hill appeared in front of me, and after turning over the hill, a huge karst cave appeared in front of me again.

This cave is different from the previous deep underground passages, the biggest feature of this cave is that it is spacious, and it is connected with the outside, like a half-exposed giant grotto, with complex roots and a very large cave entrance. Staggered, even if everyone is lying outside, they can see it clearly.

This scene attracted Ye Xun's attention, and while he was hesitating, Huang Wenyuan, who had been following the team, suddenly got up, and without waiting for Ye Xun to greet him, he bent his waist and walked directly towards the entrance of the cave.

"Why don't you listen to the command, come back quickly!"

Ye Xun frowned, and subconsciously stopped Huang Wenyuan, who knew that the other party didn't care about him at all, just glanced back lightly, and said with disdain,

"Why are you calling at me, really taking yourself as a character?"

“……”

Ye Xun was speechless, he was indeed not a person in the system, and he was not qualified to point fingers at this high-ranking cadre, seeing that the other party was unwilling to cooperate with him, he could only hold back his anger and said patiently,

"You have to think clearly, the environment everyone is facing is so harsh now, if you can't work together, I'm afraid that no one will be able to escape, and your behavior will not cause any benefit to yourself."

"Hehe, scare whom!"

Huang Wenyuan didn't care about Ye Xun's warning at all, shook his head with a rebellious face, and walked forward on his own, Ye Xun had no choice but to give up persuasion when he saw this, continued to stay where he was, and sighed,

"Forget it, he wants to act alone, just let him go by himself, let's not be impulsive for now, wait and see."
