The four-rotor light reconnaissance drone, painted in dark gray, rose from the top of a van parked behind a mound. However, in the blink of an eye, it disappeared into the dark night. In the van, the strong body Harbala hunched his waist a little afflictedly, and sweated his head and fiddled with the control platform that controlled the drone.

Thanks to Fu Xiaofei's modification technology, the camera installed on the drone has been greatly improved and upgraded. Not only has the camera's observation magnification been improved, but it has also added a relatively sensitive thermal imaging function. Judging from the mirror image of the camera feedback installed on the drone, the posts hidden in weeds or semi-underground concealed fortifications outside the transport base are all exposed. However, the groups of snipers discovered by Gu Weisu seem to have used anti-thermal imaging detection equipment and did not appear in the thermal imaging screen.

Controlling the drone to rise to the corresponding height, Halbala observed two different types of images transmitted by the drone, while quickly transmitting the received image data to the military tablet computer carried by Tang Guoming and others: "Boss, I have calibrated all the detected posts on the periphery of the target building. But I can't see several groups of snipers, so I can only leave it to the fried liver to calibrate!"

As he finished speaking, seven or eight places marked with eye-catching red light spots suddenly flashed on the display screen in front of Harbara, and Gu Weisu's voice also came out clearly from the communicator: "If you want to alert the target building, these points are the best blocking positions for the sniper team."

After carefully observing the pictures and information transmitted by Harbala, Tang Guoming's brows slowly frowned: "The external channel of this transport base is a very standard Y-type channel, but two of them were obviously just established, which happened to lead to the forward base built by two low-end mercenaries. The other is the source channel for materials... Don't you think the source channel for materials is a bit awkward?"

After glanced at the Y-shaped path displayed on the military tablet, Pan Guan pointed to the material source channel without hesitation: "It has been changed straight! The material source channel uses the old highway that originally led to the villages and towns. Locals will not have any intention to make the road construction, especially for such villages and towns that are basically in semi-primitive. It is good to walk on the road. It is impossible to have the intention to build the road so horizontally and vertically."

After reaching out to gesture on the image data reflected by the military tablet computer, Tang Guoming nodded in agreement: "The locals always follow the direction of the terrain and water flow. The smaller the project volume, the better, so... at least three places have straightened the roads! So the problem is - at least two places have to straighten the roads to fill it, but there are no obvious traces of soil extraction near the roads. Where did they get the soil?"

Staring at the terrain image uploaded from the drone, Halbala pressed the communicator button hesitantly: "Theoretically... it is a valley about six kilometers away from the highway, and there are traces of ruts on the ground. Wait, I will control the drone to go and take a look..."

In the blink of an eye, Harbala's voice came out from the communicator again: "There are indeed soil extraction pits in the valley, but there are several soil extraction pits, which makes no sense... These guys are so environmentally friendly, and they have to disperse the soil to get it? Could it be that they still want to protect the nearby terrain and protozoa and plants?"

Looking 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?"

After glanced at the path that Pan Guan pointed out, Tang Guoming shook his head slightly: "Do you smell it?"

With a gentle sniff, Pan Guan suddenly realized: "The wind blew from the direction of the path, with the smell of rotten animal corpses. In other words... this path was also targeted by those guys?"

Tang Guoming nodded: "It should be mines and traps with early warning devices. Only larger animals killed by these two things will emit a rotten smell of animal corpses that can spread farther with the wind. Let's take a straight line down the river, and then cross the river and walk in the middle of the mountain on the side of the valley. If I'm not wrong... The original villagers should now be in a certain soil extraction pit in the valley!"

After a breath of breath, Tang Guoming reached out and pressed the communicator button again: "Dagong, continue to collect all the information near the target building, and at the same time, he told Abdu to ensure that all participants of the war remain quiet. Fry the liver and keep the surveillance. The judge and I went to the valley where these guys were taking soil!"

Avoiding the path that was obviously hidden with danger, Tang Guoming and Pan Guan formed a horizontal lineup about twenty meters away. With the help of the cover of the grass and terrain, they quickly touched the river that was about to dry up.

Obviously, due to the weather, the water level of the river dropped very seriously. The water surface in some places could almost only flood the knees of Tang Guoming and Pan Guan. Carefully tentatively trampled on the stones in the river with their toes. Tang Guoming and Pan Guan tried not to let their actions when crossing the river, causing too much turbidity to occur, so as not to disturb the opponents who might appear by the river downstream of the river. It took a long time to tread through the river, which was not too wide.

He raised his hand to play the tactical sign of "follow forward" towards Pan Guan. Tang Guoming was still hunched over and walked towards the middle of the mountain on the side of the valley. While walking, Tang Guoming and Pan Guan also carefully stepped on the stones exposed outside the soil, so as not to raise dust and drift away with the wind and expose their whereabouts. After walking carefully for an hour, Tang Guoming and Pan Guan finally approached a pit nearest to the entrance of the valley.

After pulling off the night vision device worn on his head, Tang Guoming looked at the ruts next to the soil extraction pit at the bottom of the valley, and then looked at the loose mounds of soil that were abruptly in the soil extraction pit, and couldn't help but sigh slightly: "I guess it's here, right?"

Nodded in agreement, Pan Guan hunched his back and made preparations to slowly slide down the hillside to the bottom of the valley. But before Pan Guan began to slide, Tang Guoming grabbed Pan Guan's arm: "There are landmines and early warning devices on the path leading to the valley. Do you think there will be no here?"

He quickly pulled out a dagger from behind his waist, and Pan Guan whispered to Tang Guoming: "Then I'll go down and explore first!"
