After Accidentally Killing an NPC, Reality Synchronized

In 2025 AD, the seventh generation of the world's top special operations simulation game "Operation Delta" was launched. Using revolutionary "neuroimmersion" technology, players can get a 95% realistic battlefield experience. However, three months after the game was launched, top players from all over the world began to receive mysterious invitations: "Your battle will no longer be limited to the screen." The protagonist Lin Ye is a former member of the Delta Force. After retiring due to post-traumatic stress disorder, he became the top technical anchor of "Operation Delta". When he accepted the invitation to enter a secret test called "Project Undercurrent", he discovered that the boundary between the so-called "game" and the real world was collapsing - every mission in the game corresponds to a real crisis that is happening or is about to happen in reality.
