The science fiction war game "Star Fortress" presupposes that humanity is defeated and retreats to Stockholm, and the official forcefully tampered with the plot to crush players in Shanghai and New York. Ordinary people at home and abroad, including deliverymen, veteran welders, overseas students, and Wall Street white-collar workers, were unwilling to be manipulated by the script and formed a coalition across the ocean to defend Shanghai. They broke through the barriers between virtual rules and reality, used ordinary bodies to fight against the established fate, and used their blood and perseverance to write a passionate epic of humanity across mountains and seas.
