Beneath the Firmament: The Silent Watcher

In 2011, ordinary university student Sun Lin walked through the doors of Jiangcheng Beifeng Aviation, thinking he had landed a secure job for life. Administrative chores? Running errands for the engineers? He became an inconspicuous “watcher” of a major national project. This isn’t a spy thriller. It’s the real, silent battlefield of China’s defense industry! Administrative procedures, subcontracting agreements, network ports... Every corner hides a deadly threat. From a green rookie to a key state-security informant, Sun Lin guards the cutting edge from an ordinary post, with a backbone of steel. Fourteen years of turbulent change. See how the “watcher,” beneath the vast skies, uses loyalty as armor and intelligence as a blade to forge an iron Great Wall protecting the skies in a war without gunfire! Behind the rise of a great nation are countless unsung women.
