Blade 2046: Dawn Front

In 2046, Dragon Nation's aerospace, military industry, and space agriculture technologies lead the world. On the southwestern border, border defense lieutenant Li Ming leads a cross-border drug interdiction mission, only to discover the targets are not ordinary traffickers but special operations teams from an old hegemonic power conducting covert infiltration. The foreign enemy, unable to wage open large-scale war, initiates Operation Withered Leaf: using drugs to erode people's livelihoods, colluding with domestic moles, digging underground tunnels, and seeking to create border instability to gradually dismantle Dragon Nation's foundations. Intelligence is tampered with, charges are forced upon them, and Li Ming and his comrades are branded as traitors overnight, wanted nationwide. In desperation, the duo holds key evidence of the enemy's stolen cutting-edge individual combat armor, navigating the underground tunnel network. They evade their own forces' pursuit while confronting foreign heavy special operations and intelligent combat machines. Two generations of high-tech military equipment clash head-on, with multiple factions scheming against each other. No cheat systems, no mindless power-ups. Relying on tactics, intelligence, tacit understanding, and iron will, they tear through the transnational conspiracy shrouding their homeland, waiting for dawn to break on the dark border. — Description from novelcodex.org
