Turn 86:
Well, first thing I notice is another good request from Rome for 100 gold. Not too sure how much gold I have sent to Rome by now, luckily I am making enough gpt due to Marco Polo.
Attention is on Quanzhou initially with wonder charging and harvesting of the copper. Petra is at 251/400 which means that two more charges will safely net the wonder with a maximum overflow of 5 (which disappear if previous wonders are anything to go by). The second builder is harvesting the copper for 180 gold which is reinvested into a water mill much to Sulla's displeasure.
At Shangdu, the water mill, that is purchased, results in an additional envoy to Seoul (now at 2 envoys). I have the option of sending a third envoy to Seoul later once I get a campus. The additional hammer at Shangdu will add to the overflow into the walls. With the Eureka kicking in for construction, research is set on it. machinery and stirrups are now both 1 turn short of finishing any time I would like to get crossbows and knights. I will add a few more chariots first before heading for stirrups. Maneuver will be an option once CS kicks in as I will not be using Limes for a while.
As for the remainder of the turn, the settlers are getting close to their destinations. Quanzhou ramps up production again via tile rearrangement. Petra will hopefully add more hammers to finish the temple on T92 as I will need to invest one turn production into Jebel Barkal which has been planted. Charging will commence next turn.
At Hangzhou, I am producing walls for another turn to get them to 78/80 to then finish the campus as soon as possible. An overview of production and invested hammers shows:
Hangzhou: 19.8 hammers,
walls 39/80 (T87 78/80) -> campus 52/117 -> archer/chariot
Shangdu: 15.4 hammers, granary 54/65 ->
walls 30/80 (T88 64/80) -> archer/ chariot/trader
Quanzhou: 17.6 hammers, temple 17/120, Petra 251/400, Jebel Barkal 0/400 -> granary/builder
Shanghai: 8.4 hammers,
walls 38/80 (T88 72/80) -> quadrireme
Beijing: 12.1 hammers
walls at 75/80, granary 46/65 -> builder
Kashgar: 4.4 hammers next turn at 6.6 walls 37/80 (T88 58/80) -> granary
I indicated the potential production after the current projects. I also indicated the walls' status for each city at T88, the turn I will most likely switch off Limes.
I would like to start some naval units using maritime card for +100% in order to generate some overflow at Shanghai. The production capacity is rather low at the moment, but should increase once the hills to the west are part of the city. The question will be what to produce in Kashgar after its walls production. The city will need a granary for more housing and surely some tile improvements to get off the ground. The two new cities could both be set on galleys/quadriremes with the +100% cards in play. They as well as Quanzhou could add the walls later on.
As for missionaries, I hired a new missionary at Quanzhou to quickly convert the new cities. The missionaries in the east are in place to convert the next city and in the Ocean. By the way, Sulla, I checked and it seems a missionary can also only move 2 tiles inside the water each turn. So, your galley can take position accordingly to protect it. As long as your galley is on the tile that my missionary will move to during my turn, it should be safe.
A quick calculation shows, that with the additional 5 city conversions and Petra, China's gpt should increase to roughly 70.
