In 2035, a virtual reality tactical shooting game called "Operation Delta" became popular all over the world, but no one knew that there was a shocking secret hidden behind it. Former special soldier Chen Feng was accidentally involved in an internal fight at a gaming company and was forced to become the leader of a team of mysterious operators. While performing a series of seemingly ordinary missions, this team of "marginal people" with their own unique skills gradually discovered that the game was actually a testing ground for the military to monitor high-risk elements. When the truth emerges, Chen Feng must lead the team to make a choice between virtuality and reality - to become a pawn of power, or to tear up the shadow agreement and return the truth to the world? The smoke-filled battlefield, the conspiracy of swords and swords, and the comradeship of life and death, everything starts from here.
