The Timurids led by Taimur e Lang, the man who conquered the most territory in history since alexander, doesn't die en route to China and goes up against the Ming dynasty

who wins?

Keep in mind Taimur is probably a top 5 general in history ... he's undefeated and conquered all of Persia, parts of modern day Iraq, C Asia, and parts of India

But the most important thing is that he defeated the Golden Horde Mongols ... the same guys who embarrassed beyond belief the Ming dynasty in the Tumu Crisis where just 30k Mongols destroyed an army of 500k Chinese killing 200k+ of them ....

they were beaten badly again in another fight with the Mongols

And unlike the Mongols, he Timurids preferred urban fighting rather than the open fields ...

I think he smashes China ... especially when its rumored that he could build a force of around 100k men ...
