At dawn, the convoy set off, because of the previous lesson, did not dare to use helicopters, all of them were vehicles with good off-road performance. Yan Biao led the team in the front, mainly capable combatants, with equipment and material vehicles in the middle, and Qi Xiaoyang and Qiao Ya led a platoon of people to hold back.

Passing through the bottom of the lake, there is a so-called karst landscape, along which there are many mounds of earth left by weathering, ranging from a few meters to tens of meters high, and of various sizes. Although the road conditions are very bad, fortunately, the vehicle performance is superior, and it takes more than 80 kilometers to reach it in four hours. Approaching the gray fog area, Yan Biao asked the team to stop advancing, and sent three soldiers wearing protective suits to advance to the edge area to try the reaction. As a result, as recorded in previous documents, the fog was not too thick, the visibility was about 100 meters, the fog was not harmful to the human body, and the communication and electronic equipment were normal. It's a strange fog, obviously devoid of moisture, like smoke but not drifting, not dissipating, not at all like something in nature.

Yan Biao gave an order, and the team drove into the fog area along the route of the scientific expedition team, and the people around him used three satellite phones to keep in touch with the temporary command post set up at the military station, and he used the walkie-talkie to keep in touch with the commander of the entire team.

When the team reached a two-kilometer position, there was a sudden abnormality, all the communication equipment failed, only a noisy current sound was left in the speaker, the GPS and other electronic equipment were all disordered, and the car was all dead and could not be started again!

A team of more than 200 people quickly alerted on the spot in accordance with the response plan in advance. But after waiting for more than ten minutes, there was no other movement, Yan Biao was in a dilemma, and sent a message for Qi Xiaoyang to discuss in the middle of the team.

"I want to take a few people to the front to touch it for a while, you take everyone to stay put, if I don't come back for an hour, you immediately lead everyone to withdraw!" Yan Biao arranged.

Qi Xiaoyang nodded: "Okay, I think I have to send a few people back, go out of the fog area to report the situation to the military station, and stay outside to answer." ”

The two heads acted at the same time, Pan Changfeng shrunk the team into three circles, and Qi Xiaoyang stayed in the middle and waited. In a few minutes, a few gunshots suddenly rang out in the direction of the turn, Qi Xiaoyang dodged and rushed back, a distance of several hundred meters was supposed to be in the blink of an eye, but due to the low visibility, Qi Xiaoyang had to make a few pauses, this delay, when he arrived at the place where the gunshots rang out, only the three soldiers sent out on the ground were shot in the head.

Before he could take a closer look, he noticed that bullets were flying out from behind the mounds in different directions more than ten meters away, Qi Xiaoyang suddenly moved his body away and pounced on one of the mounds in a zigzag line! The moment he crossed the mound, Qi Xiaoyang saw a sniper wearing loess-colored clothes and pants all over his body, who was arching up from the ground to run. Qi Xiaoyang is not good at using guns, but he has prepared a lot of pistol bullets in his marching bag, and when he shakes his hand, two of them fly out, bend his legs and hit his head, and immediately knock them back to the ground.

At this pause, two more sniper bullets followed, Qi Xiaoyang concocted the same method, cleaned up the second sniper, and then pounced on the third, but the rest were gone. Qi Xiaoyang didn't chase after him, he turned around and prepared to arrest a live interrogation, who knows that it will only be one or twenty seconds, and these two snipers have already lost their breath! Although Qi Xiaoyang threw the bullet quickly and accurately, the strength was not as good as that from the chamber of the gun, but the two people were seriously injured, they all committed suicide because they couldn't escape, what kind of way Qi Xiaoyang couldn't see, neither like taking poison, nor external injuries.

Worried that there would be another problem on the team's side, Qi Xiaoyang immediately rushed back, but fortunately, there was still no movement here. Qi Xiaoyang looked at some small mounds around him, and quickly searched again, and saw that there was no ambush, so he settled down.

Three people were sacrificed, but they finally knew that the other party was also human, which made people feel less afraid. Qi Xiaoyang took a squad of soldiers and prepared to get the two corpses over to study, but he didn't expect that when he returned, only some blood stains were left on the ground, but the corpses were gone, so he could only bring the remains of the three comrades.

Now the situation is obvious, the opponent hiding in the shadows has blocked the way back, and intends to leave all the people who came in, Qi Xiaoyang analyzed from the opponent's combat strength just now, he can easily deal with it, so he is not afraid at all, if he didn't make an appointment with Yan Biao to wait for an hour, he would have led the team to rush inside.

Half an hour later, Yan Biao and the others came back, and there were only six of the fifteen people left, and even Yan Biao was slightly injured! "Sure enough, it's not a ghost, it's all done by people! They are all masters, and one of them is very powerful!" Yan Biao said as he showed Qi Xiaoyang the injury on his calf: "Look at what kind of strange weapon this is?"

Looking at the thin blood line on Yan Biao's arm, Qi Xiaoyang subconsciously touched his thigh. "Could it be him? Tell me what was going on!"

It turned out that Yan Biao led people to walk less than two kilometers inside, and found the vehicles and equipment left by the scientific expedition team, where they were also ambushed. Two of the warriors were shot with sniper rifles, while the other seven were killed in a sneak attack by three men in gray, who were so clever that they could suddenly emerge from the sand, and their weapons were not only pistols, but also a strange knife with thin blades. Yan Biao injured one of them in the battle, but another more powerful man in gray pounced and fought with him for a few rounds, the two were equally powerful, and the man was finally kicked by Yan Biao, and at the same time, he didn't know what weapon to cut a thin hole in Yan Fei's calf, and then they all disappeared into the mist, and the fog inside was much thicker.

"It's really a bit like, the little devil is not small, he dares to come here!" Qi Xiaoyang heard this situation, which was somewhat similar to the short fight between the turtle breathers of the island country last time, so he told Yan Biao his guess.

After the two discussed, they felt that the fog inside was too thick and not suitable for the play of firearms, and with the skills of the other party, the soldiers who rashly attacked it might suffer greater casualties, so they decided to withdraw first. This retreat was explored by Qi Xiaoyang, Yan Biao was postponed, but there was no ambush, and he successfully returned to the outside of the fog area, it is estimated that the other party knew that there were also two masters here, so they withdrew the ambush.

Although all the vehicles were lost, all the important equipment was brought out, and communications were restored to normal. After Yan Biao reported the situation on the phone, he was instructed to retreat two kilometers and stand by in place.

After settling the team, Qi Xiaoyang's Yan Biao called to the side and asked in a low voice, "What do you think will happen above?"

Yan Biao thought for a while and said: "There are three relatively large possibilities, one is to increase the number of troops and use the tactics of a sea of people; the second is to use artillery or even missiles to bomb and search again; and the third is the old method!"

"Don't the latter two consider their own people inside?" Qi Xiaoyang's heart was cold.

Yan Biao shook his head with a wry smile and said, "It's not something I can guess, let's look at the meaning above." ”

"That's it, you watch outside, I'll go in and take a walk!" Qi Xiaoyang didn't use a tone of discussion, but said resolutely.

Yan Biao was startled, and hurriedly grabbed him: "This can't be done no matter what, if something goes wrong, how can I afford it!"

"Don't worry, now that I know they're just a bunch of people, I'm sure I'll be able to get out safely. You wait for my news. Qi Xiaoyang patted Yan Biao's hand.

"You insist on going, then the two of us will go together, so we can take care of it!" Yan Biao saw that he couldn't stop him, so he wanted to follow, he was not Qi Xiaoyang's superior, and he had no right to give orders directly.

"Okay, then let's explore this Longtan tiger's den together!" Qi Xiaoyang's eyes flashed with excitement - he wanted to uncover this mystery that had plagued the Huaxia military for ten years!

There was no need to take care of the soldiers, Qi Xiaoyang and Yan Biao only arrived at the location where they had been ambushed before, and the fog here was really much thicker, and they couldn't see anything from thirty meters away. The corpses of the sacrificed soldiers were still lying there, Qi Xiaoyang's eyes were on fire when he saw it, these people were all brought by him from the Lijiang base!

"You follow me a few meters away, I'll lure them out!" Qi Xiaoyang said this to Yan Biao, and immediately flashed forward a few meters from behind the car where he was hiding, and then strode forward. Yan Biao didn't hold it, so he had to follow behind with a 92-style hand.

After walking a few hundred meters away, Qi Xiaoyang saw that there was no attack, and his heart became impatient, so he turned around and gestured like Yan Biao, and began to leap into it quickly at a distance of about twenty meters each time. The concentration of the fog did not increase until three kilometers later, Qi Xiaoyang's eyes lit up, and a fog-free area with a radius of half a kilometer appeared in front of him, only there was no fog on the ground, and the fog was still covered like a pot lid in the air of twenty or thirty meters;

There was not a single figure in sight around, only a ten-meter-high semicircular hole with a white glow, like a huge mouth with its fangs bared in the dark environment shrouded in mist. Hidden behind a mound of earth and observing for a few minutes, there was no movement in the cave, Qi Xiaoyang instructed Yan Biao beside him: "You just stay here to answer me, I will go first to find out the situation." ”

"Hey-" Yan Biao's words were still in his throat, and Qi Xiaoyang had turned into a streamer and shot into the hole.
