Under the Sky: the Silent Watcher

In 2011, Sun Lin, an ordinary college student, stepped into the door of Jiangcheng Beifeng Airlines and thought she had an "iron rice bowl." Administrative chores? Technical errands? He became an inconspicuous "watchman" of a powerful weapon. This is not a spy movie, this is the most realistic silent battlefield of China's military industry! Administrative procedures, outsourcing contracts, network ports... There are hidden dangers everywhere. From a young rookie to a key informant of the National Security Bureau, Sun Lin used her hardest backbone to guard the cutting-edge edge in her ordinary position. Fourteen years of turmoil. See how the "Watchers" use loyalty as their armor and wisdom as their blades under the sky to build the Great Steel Wall that defends the sky in a war without gunpowder! Behind the rise of great powers are thousands of silent people.
