In 2045 AD, Hua Penguin Company developed the epoch-making immersive game "Operation Delta: War of Resistance". Special operations team leader Lin Feng became the first tester.
His consciousness was thrown into the torrent of history, from the snowy night of September 18th to the ruins of Songhu. Sometimes he transformed into a platoon leader who defended his position, and sometimes he was a strategizing commander, risking his own life in every key battle.
However, the game was far more than he imagined. He can not only create local miracles, but he must also experience the true meaning of sacrifice in the doomed defeat. When the weight of history and the memories of his comrades are superimposed on him, Lin Feng gradually blurs the boundary between virtuality and reality - this is not just a test, but a journey home that must be engraved in the soul.
