"Given the scale of Tanya Mining, there's no need for Kuang Zhuoma to deceive us. What I'm really curious about is why Tanya Mining abandoned the development of Great Demon Lake. Can we find that part of the information?"
Liang Wei asked his deputy.
"It's difficult. We would need to use top-level clearance and sacrifice two to three valuable undercover lines. I can send a report if you insist."
Liang Wei waved his hands repeatedly: "Then forget it."
The deputy nodded and then added, "However, we can be sure that Tanya Mining did not engage in large-scale military operations targeting Great Demon Lake. Their exploration activities over the past six years are no different from what we're doing now."
"Don't be so confident. They've been developing super deep drills (a type of semi-mechanized fourth-tier troopers) for nearly a decade. When it comes to exploring ancient ruins, even Black Star's war machines can't keep up."
