As he spoke, he invited the other party to disy a video on the screen. After adjusting the progress bar, the individual stepped aside and offered a respectful gesture to Li Yalin, encouraging him to watch.


    The video depicted a train approaching the Duke Mining loading yard.


    In the distance, Duke Mining sprawls across a vast yellow-white in. Along the train’s path, Duke Mining’s phosphate mining areas nk both sides, where numerous construction machines operate at high speeds.


    Interestingly, within the expansive phosphate mining area shown in the video, many workers are seen constructing and welding iron towers towering at least 20 to 30 meters high. These iron towers resemble high-voltage line towers, but they feature tforms for people to stand on at mid and upper levels. Judging by the size of the workers in the footage, each tower can likely support at least seven or eight individuals at once. Throughout the mining area, at least a dozen such iron towers have been erected, with several more currently under construction.


    Li Yalin paused the video, pointed at the towers, and remarked to Charlie, “Mr. Charlie, these towers appear to be intended for warning purposes. It seems they are indeed enhancing security measures.”<h3 style="background-color:DodgerBlue">


    Charlie nodded in agreement, stating, “The terrain there is very t,posed entirely of phosphate mining areas. There are no tall buildings nearby. The height of these towers allows for distant observation. If equipped with professional security equipment, it would be quite challenging for anyone to breach the area. Furthermore, from what we see in the video, the mining area is still a considerable distance from the heart of Duke Mining.”


    “Exactly,” Li Yalin replied. “I reviewed the data on Skyline. They’ve expanded the mining area over the years to at least six kilometers in all directions. Since the mining area is moving further out, they’ve constructed several conveyor belts to transport the extracted ore to the refinery. If an intruder were to approach from the periphery, prating such a long distance would be exceedingly difficult.”


    Charlie nodded slightly, encouraging Li Yalin to resume the video. The train in the footage drew nearer to the refinery, which resembled a fortified structure encircled by high concrete walls. Caltrops and high-voltage wires were strung above the walls. Although the train tracks led directly into the refinery, a robust iron gate guarded the entrance.


    From the video, it was evident that numerous individuals were waiting outside the iron gate. As the train slowly approached, several people did not immediately open the gate. Instead, one individual boarded the front of the train to converse briefly with the driver. Following this, instructions were given for the gate to be opened, allowing the driver to enter the factory area.


    The factoryyout resembled arge T-shape, with the production area at the top and three train tracks along with two semi-enclosed loading tforms below.


    Among the three tracks, the main line runs between the two tforms, while the opposite side features two arrival and departure lines.


    In the footage, a freight train was parked on the left arrival and departure line, while the train in the video passed the switch and halted on the right arrival and departure line.


    At this point, numerous staff members were present on the right tform, actively transporting the produced phosphate to the loading area, awaiting the arrival of empty carriages from the train. As soon as the train reached the station, they would begin loading the empty carriages.


    However, both Charlie and Li Yalin perceived a deeper purpose behind their actions. The loaders appeared strong and agile, resembling martial artists, diligently working on the tform as the train arrived. It seemed their true intention was to monitor the trains entering the station vigntly, ensuring against any potential attacks.


    Once the train in the video came to aplete stop, it uncoupled and began to change direction before towing the fully loaded train from the opposite side onto the departure line. The entire process was efficient, taking only a short time, with nearly a hundred staff members of various roles consistently present on the tforms nking Duke Mining.<fnedba> Readplete version only at find?novel</fnedba>
