In the year 2040 of the Blue Star Calendar, the mysterious game "Operation Delta" comes to reality and is deeply bound to the national destiny. All adult citizens around the world must enter the "War Zone" to compete for resources. The loser will not only lose all their assets, but their country will also be punished by natural disasters. Haf Coin becomes a hard currency that can be directly exchanged for real currency or to purchase lifespan. The protagonist travels to a parallel world and discovers that although the people here have extraordinary physiques, they do not understand the real tactical game. As the top "special agent" in the previous life, the protagonist uses information gaps and extreme operations to fight against the great powers and rebuild the glory of the Dragon Kingdom through high-end gameplay such as "using small to make a big difference", "malicious team formation", and "seizing the body" in the national destiny battlefield.
