Split the Earth: Red Flag and Dragon Flag

An unexpected space-time rift opened, connecting two unrelated worlds. Twenty years ago, a group of ordinary people from modern civilization were swallowed up by the rift and fell into a different world where cold weapons and feudal dynasties coexisted. They were hunted as monsters, forced to give up their knowledge, and then discarded like grass after being squeezed dry. Twenty years later, an expeditionary force crossed the rift and set foot on this land. They brought steel, fire, and an answer they had waited too long. In the ruins of the north, a girl who escaped from the cold palace put on a military uniform. In the mist and rain in the south, a prince from the Pian'an Dynasty picked up a foreign gun. When the five-star red flag rises on the city walls of another world, and when the outline of an American warship appears on the southern horizon - everyone on this continent must answer the same question: What should tomorrow look like? This is not a simple conquest, nor an ordinary war. This is the first echo when two worlds meet.
