A light quadcopter reconnaissance drone, painted dark gray throughout, rises from the top of a van parked behind a mound like a large bloodsucking mosquito unique to Black Africa. But in the blink of an eye, it had disappeared into the dark night. In the van, the sturdy Halbara was hunched over his waist and sweating profusely as he fiddled with the control platform for the drone.

Thanks to Fu Xiaofei's modification technology, the camera installed on the drone has been greatly improved and upgraded. It not only improves the observation magnification of the camera, but also adds a relatively sensitive thermal imaging function. Looking at the mirror image of the camera feedback installed on the drone, the sentry posts outside the transfer base that are hidden in the grass or semi-underground sheltered fortifications are all exposed. However, the several groups of snipers discovered by Gu Weisu seemed to use anti-thermal imaging detection equipment, and did not appear in the thermal imaging screen.

Controlling the drone to rise to the corresponding height, Halbara observed the two different types of images transmitted by the drone, and quickly transmitted the received image data to the military tablet computer carried by Tang Guoming and others: "Boss, I have calibrated all the detected sentry posts around the perimeter of the target building. But I can't see a few groups of snipers, so I can only leave them to fried liver for calibration! ”

When the words fell, on the display screen in front of Halbara, seven or eight locations marked with eye-catching red light spots flashed, and Gu Weisu's voice also came out clearly from the communicator: "If you want to guard the target building, these points are the best card positions for the sniper team." ”

Carefully observing the picture materials transmitted by Halbara, Tang Guoming's brows slowly wrinkled: "The external passage of this transfer base is a very standard Y-shaped passage, but two of the passages have obviously just been established, and they happen to lead to the front exit base built by two low-end mercenaries. The other is the source channel of supplies....... Don't you think the source of that material is a bit awkward? ”

Glancing at the Y-shaped path displayed on the military tablet, Pan Guan pointed to the source of materials without hesitation: "Straightened!" The source of materials uses the old road that originally led to the village and town, and the local people will not have any deliberate planning to build the road, especially in this kind of village and town that is basically in a semi-primitive state, it is good to have a road, and it is impossible to have the heart to build the road so horizontally and vertically. ”

Stretching out his hand to compare a few times on the image data embodied in the military tablet, Tang Guoming nodded approvingly: "The local people have always followed the terrain and the direction of the water flow to build roads, and the smaller the amount of work, the better, so ...... Roads have been straightened in at least three places! So the question is - in at least two places, the road straightening requires a lot of earthwork to fill, but there are no obvious traces of soil near the road, where did they take the soil? ”

Staring at the topographical images uploaded back from the drone, Halbara hesitantly pressed the communicator button: "Theoretically...... Even in the valley, which is about six kilometers from the road, there are also traces of ruts on the ground. Wait a minute, I'll control the drone and go over and see ......"

In the blink of an eye, Harbara's voice came out again from the communicator: "There are indeed pits in the valley, but there are several, and this doesn't make sense....... These guys are so environmentally conscious, and they have to disperse the soil to get it? Could it be that they also want to protect the terrain and native flora and fauna of the area? ”

Glancing at each other, Tang Guoming and Pan Guan slowly retreated and climbed down the ridge, squatting behind a rock. Looking around at the terrain around him, Pan Guan raised his hand and pointed to a path leading to the valley: "From here?" ”

Glancing at the path pointed out by Pan Guan, Tang Guoming shook his head slightly: "Do you smell it?" ”

With a slight snort, Pan Guan suddenly realized: "The wind is blowing from the direction of the path, carrying the smell of rotting animal carcasses." Other words...... This trail is also being targeted by those guys? ”

Tang Guoming nodded: "It should be a mine and a trap with an early warning device, only the larger animals killed by these two things will emit the smell of rotten animal carcasses that can spread far away with the wind." We descended the river in a straight line, crossed the river and walked to the middle of the mountain on the valley side. If I'm not mistaken...... The original residents of the village should now be in some kind of excavation pit in the valley! ”

Taking a slight breath, Tang Guoming reached out again and pressed the communicator button: "Dagong, continue to collect all the information near the target building, and at the same time explain to Abdu, let him and the people of his tribe ensure that all the participants remain quiet." Fry the liver, keep an eye on it, and the judge and I will go to the valley where these guys have taken the soil! ”

Avoiding the path that was obviously lurking in danger, Tang Guoming and Pan Guan formed a horizontal team at a distance of about twenty meters, and with the help of the cover of grass and trees, they quickly touched towards the small river that was about to dry up.

Apparently because of the weather, the water level of the river dropped very badly. In some places, the water surface can almost only be submerged to the knees of Tang Guoming and Pan Guan. Carefully stepping on the stones in the river with their toes, Tang Guoming and Pan Guan tried not to let themselves cross the river, causing too much turbidity of the water flow, so as not to disturb the opponents who might appear on the riverside in the lower reaches of the river, and it took a long time to wade through the small river that was not too wide.

Raising his hand towards Pan Guan, he played the tactical sign language of 'follow forward', Tang Guoming still bent his waist and walked towards the middle of the mountain on the side of the valley. When walking, Tang Guoming and Pan Guan were also very careful to step on the exposed stones as much as possible, so as not to raise dust and scatter in the wind when they were walking, revealing their whereabouts. After a careful hour's walk, Tang Guoming and Pan Guan finally approached the nearest excavation pit to the entrance of the valley.

Pulling off the night vision device on his head, Tang Guoming looked at the ruts next to the earth-taking pit at the bottom of the valley, and then looked at a few loose mounds of dirt in the earth-taking pit, and couldn't help but sigh slightly: "I guess it's right here, right?" ”

Nodding approvingly, Pan Guan bent down his waist and made a preparatory move to slowly slide down the hillside to the bottom. But before Pan Guan began to slide, Tang Guoming grabbed Pan Guan's arm: "There are mines and early warning devices on the path leading to the valley, do you think there will be any here?" ”

Quickly pulling out a dagger from behind his waist, Pan Guan whispered to Tang Guoming: "Then I'll go down to explore first!" ”
