In Star Year 2345, Lin Rui, an outstanding federal lieutenant colonel officer, accidentally traveled to the border town of Carlo Empire in 376 Years of Iron Fire when his transport plane crashed due to an energy storm during an emergency border raid, and possessed the captain of the escort team of the same name. At this time, the town had just been raided by the Black Flag Army. It was devastated and the escort suffered heavy casualties. Lin Rui relied on modern military knowledge to command the remaining troops to successfully repel the Black Flag Army forward. But knowing that the crisis was not over, he decided to lead everyone to the Imperial Army's border fortress "Rock Castle" fifty miles southeast to seek refuge. In this chaotic era where cold weapons and early gunpowder weapons coexist and wars are frequent, how will Lin Rui survive in a desperate situation? How will he change the fate of himself and those around him, and write a legend of iron and fire?
Intention: Reversal of fate
