"Boss, why is there no signal? Xingsheng, you should think of a way! Seeing that the transmission signal was lost, Wang Xiaopang asked anxiously.

"Don't worry, this is not the first generation of reconnaissance eyes of the military department, this is the second generation of fully intelligent type, and they will make corresponding countermeasures according to the actual situation." The Prosperity explained proudly.

As soon as the Xingsheng finished speaking, the reconnaissance eye withdrew from the fog area and was suspended in mid-air, and the signal was connected again.

Seeing those reconnaissance eyes suspended motionless in mid-air, Wang Xiaopang asked again: "I said, Xingsheng, which one are you making trouble, this reconnaissance eye has come out, how can you reconnoitre?" ”

Xingsheng didn't answer Wang Xiaopang's question, but only pointed to the holographic map.

In a few moments, all the scouting eyes were seen flying to the Dark Lands. Half an hour later, all four thousand miniature reconnaissance eyes gathered in the misty area, neatly suspended in mid-air, and the dense small spheres in the sky from a distance made people feel very shocked, except for dense phobia.

At this time, the Xingsheng sent a command, and then saw the 4,000 reconnaissance eyes, swarming into the fog area, staying suspended in mid-air every fifty meters, in order to establish a short-frequency link and ensure smooth signal transmission.

After a while, the holographic map opened again, and it was still a gray fog with nothing else in sight, and the reconnaissance eye flew about twenty kilometers, and the fog gradually thinned.

A few minutes later, the fog disappeared in front of it, and what appeared in the field of vision was a very huge canyon, the canyon was about five thousand meters in diameter, and the depth was about more than two hundred meters.

It was a semi-circular fortress, about two kilometers in diameter, and the beacon lights on the fortress flickered brightly and dimly, and there were soldiers in armor and weapons patrolling back and forth in the lanes of the fortress.

At this time, Lin Yifan and Wang Xiaopang stared at everything in front of them with big eyes in shock, they never thought that there would be such a big fortress here.

"Boss, this fortress is so big, how can we find Sister Swift? The defense is still so tight, even if you find the two of us, how can you go in and save people. Looking at the well-defended fortress, Wang Xiaopang couldn't help but smack his tongue.

"What, you're scared sometimes?" The Prosperity sneered as soon as it took the opportunity.

"I... Will I be afraid? I'm worried about Brother Lin Nan and them! Wang Xiaopang was stunned, and he couldn't find the right words to refute for a while, and his face turned red with anger.

"I think this should be the private armament of those nobles, such a large fortress should have been in operation for a long time, it seems that they are indeed planning a big conspiracy behind it. It's not certain whether Shangguan Yuyan is in it or not, but I think they have been kidnapped and have nothing to do with the forces behind this fortress, so we have to search carefully anyway. Saying that, Lin Yifan gave another order to the reconnaissance eye.

Receiving the order, all the scouting eyes began to move, and they flew in a neat formation towards the valley fortress.

Although the fortress was heavily defended, it could not prevent the intrusion of the miniature scouting eye. At a distance of 100 meters from the fortress, all the scouting eyes scattered in all directions, scanning the entire outside of the fortress first, and then silently entering the interior of the fortress through the vents.

The outer armor of this fortress is made of tungsten steel, with a thickness of about ten centimeters, which is very strong, and on the periphery of the fortress annular circle, it is equipped with forty automatic guns, and it is also equipped with a far-infrared scanning system, which can be said to be immediately discovered as long as it enters the canyon, and the outer defense here has almost caught up with the military fortress, which makes Lin Yifan and Wang Xiaopang feel very shocked.

However, when the Scout Eye entered the interior, the scene inside once again shocked the two of them beyond comprehension. When you enter the inside of the fortress, you will think that this is just an ordinary military fortress, and when you enter the underground core area, you will find that this is actually an arsenal, in which countless robotic arms are constantly busy, and sets of battle armor and various weapons are neatly stacked together.

"Oh my God... Top dog. This... Is this going to war? Looking at so many weapons and equipment, Wang Xiaopang asked in surprise.

Without waiting for Lin Yifan to answer, Xingsheng spoke: "Little master, the reconnaissance eye has thoroughly scanned the entire fortress, and has not found the three of Shangguan Yuyan. ”

Although the sudden discovery made the two of them a little shocked at this time, Lin Yifan was not too entangled, his purpose was to find Shangguan Yuyan and them, and the question of the fortress was not something he should ask. Immediately let the Xingsheng back up all the information of the fortress and prepare to pass it on to General Shangguan and them.

Lin Yifan evacuated all the reconnaissance eyes and continued to search in the forest, and after about forty minutes, he found a karst cave three hundred kilometers north of the canyon, and there were dozens of black-clothed people guarding the entrance of the cave.

After the reconnaissance eye entered the cave, Lin Yifan suddenly stood up, his eyes staring at the holographic screen, and a dark-skinned person with a hideous scar on his face appeared in the picture.

"That's him!"

Lin Yifan recognized this person at a glance, although he only glanced at it at the time, but the scar on his face made Lin Yifan very sure that it was this person who shot at them with a sniper rifle.

However, this also has a lot to do with Lin Yifan's special physique, if he is replaced by an ordinary person, he will definitely not see the appearance of the sniper in the car.

Immediately after that, the reconnaissance eye began to conduct an all-round reconnaissance of the cave, which was large and had many separate rooms, and basically people were imprisoned in each room. Although Lin Yifan didn't know them, he could guess that the background of these people was definitely not ordinary.

However, what gave Lin Yifan the most headache at this time was that there were no Shangguan Yuyan and the three of them in these rooms. But his intuition told him that Lin Nan and the three of them must be in this cave, but they couldn't think of what they missed for a while.

Lin Yifan stared at the holographic screen and thought, he found that there was a corner in the innermost part of the cave, there was a tunnel with no light in the black hole, and every time the patrolling guards walked there, they would avoid it intentionally or unintentionally, as if there was some danger there.

Lin Yifan felt that there was something strange there, and quickly mobilized two groups of reconnaissance eyes and flew towards the tunnel. The Scout Eye flew to the mouth of the tunnel, turned on the scanner and began to scan the tunnel, and the scan showed that there was only metal inside, and no signs of life were found.

Lin Yifan was unwilling, he controlled a reconnaissance eye and flew inside. The walls of the tunnel are very smooth and have strange patterns carved into them, and at the end of the tunnel is a black gate that feels so strong that it is not made of ordinary materials.

Looking at the scanning information, the Xingsheng suddenly spoke: "Little master, there is a problem with this tunnel, this wall and the gate inside are made of titanium alloy, the tunnel is fifty meters long, two meters high and wide, and the reconnaissance eye also scanned that there are energy fluctuations behind the metal wall, this design is a bit like a beam cage." ”
