In a parallel world on the earth, two time travelers came to the Ming Dynasty one after another. One was proficient in the arts of hundreds of schools of thought, and the other had superior military capabilities and became the emperor of the Ming Dynasty in this world.
Since then, the human history of the earth has changed beyond recognition like a wild horse with loose reins.
More than a hundred years after the death of the time-travelers, the Ming Empire expanded into an empire on which the sun never sets. There are many factions within the empire. The advantages left by the time-travelers are lost, and the development of science and technology slows down.
The outside world gradually learned from European countries to catch up with the technological development of the empire, and military frictions and conflicts continued.
For territorial interests or to divert conflicts, various countries are gearing up to look at the Ming Empire, which owns almost half of the earth.
A new military fan traveler breaks into this world. What new changes will he bring to history?
