An update - and thanks for the feedback, guys, much appreciated.
A visit to China? Why, it is tradition by now.

It was time to go show the Ming Emperor again that he was not the son of heaven - we were.

The war started out great with a mad dash to Beijing,

...where we eliminated the Imperial Guard and laid siege to the palace.

The Ming responded in the usual fashion - gather a massive army (Honestly, how do they manage to supply close to 120k of troops?)
This was a hard-fought battle that went to the absolute wire.

The Roman forces lost much more, but kept up the siege.
This was important because it prevented the Ming from reinforcing their eastern allies:
Again, the Ming tried attacking our much-depleted armies at Beijing, this time amassing 150k troops (WTF? It would be one thing if these were low-tech forces, but Ming is fully westernized already.)

This time, the Roman lines broke under the onslaught.
Unfortunately for the Ming, four fresh legions were already marching towards them, led by the Emperor Bardas II Thanas himself.
With this victory, the legions could press onwards and started to threaten the Ming territories.
The Ming allies in the east begged for mercy...

and it was granted to them for the small price of half their territory.
The son of heaven recovered and led another massive army against the Emperor.

As usual, Roman discipline prevailed against the mass Qing artillery.
A peace treaty was soon signed...

in which the Qing Empire ceded over near-worthless desert and mountain territory again.

...but we are getting into China. Slowly. Should only take us another hundred years or so.
The war had a few side effects:

Wait...we never hired any mercenaries. So...why are former enemies begging us to sign them? No way. Get lost and be happy we did not crucify you for having that much cheek.
Meanwhile, in the new world:

We found the fountain of youth. Or not, because it has no effect whatsoever on the longevity of the Emperor, Generals or other people.
From "
Curiosities of the world", by Pennus & Giletta, Colonia Mexicana 2010:
"...we are now convinced that the water from that fountain was nothing but ordinary water drenched with an extraordinary concentration of coffee fruits, thus giving the drinker an extraordinary boost of energy. As test on the water kept in the Imperial cellar at Rome showed, it had no biological effect whatsoever."
(OOC: Seriously Paradox, either have the fountain of youth be the fountain of youth or don't bother with it).

We increased our technology.
A glorious monument to celebrate the achievements of Rome and of our dynasty? Why, there can only be one place for that.
Meanwhile, our black conquistador (see last update) sent back new maps:

...that is a lot of unclaimed land indeed.

WAR GALLEONS. And an admiralty. Hmmmmm....if only we had a city in our empire that was the epitome of Naval success and had provided the Roman Empire with huge amounts of ships in CKII....

OH YEAH.

Yes, let's do that.

Don't worry guys, even Emperors get in trouble with female warriors sometimes....oh wait, when we do,
WE MARRY THEM. You guys are pussies.

The reformed Tercio seems like the best way to deal with the mass chinese horde attacks.
Also, we could build a war college. Man, if only there was a city which was already renowned for the quality of its troops and the military schools...

*satisfied nod*

As if anybody would be surprised.
Let us try and go for more tangible riches.

Like the rich spices of Java.

I guess the Saxons are indeed a gift to civilization. Especially as all the cork-producing regions are owned by us.

An idea I don't need. (Mercs suck anyways as they don't upgrade, so if you are reliant on mercs you spent massive sums disbanding and rehiring them whenever a new troop type gets developed. Thus, mercs are not a viable alternative, making merchant republics utter shit at war due to their low manpower)

Islam is resilient, I give them that. However, our inquisition stamped this out within three years.

Who hasn't heard of the great farms of Salamanca?

Absolute rulership. Wait, we didn't have that already as Roman Emperor?
Meanwhile, the Roman and Westsaxon colonies in the new world had another fight among themselves, with nobody else caring about this.

Killing grounds. Exactly what is needed against the Chinese Hordes.
A few years later, our Emperor died.

Fountain of youth, my ass. Now we got another regency for 7 years.

Wait, you mean, just because she was fathered out of wedlock with some debutante you think she is unworthy to rule? We'll see what the legions think of that.

Not much, as it turns out. The dynasty of Thanas remained on the throne.

Meh, another idea that won't do much for us.
On:

Lithuania was integrated into the Empire.

giving our realm its biggest extent yet:
That's all for this update.
