So for the tech path, after Math, I was gone for Poly, and then Litteracy. After that (11 turn later) I searched Currency, and Calendar (due in 3 turns) for the silk and the incense.
I spread buddism in most of our cities, I forgot Turfan...

But our religion spread spontaneously to most of Bismarck's cities.
Socrates appeared in Dehli, so I build an academy in Dehli.
For the infra:
aqueduct in Dehli, library in karak (market due in 13 turn, karak MM for growth), lighthouse and library in madras, turfan library done and granary (due in 8 turns)... and I done the Great Library in Karak.
On the diplomatic side:
Hatty ask for currency... I say no!
Bismarck trade us Pig for Ivory, I accept as he didn't have construction for the moment.
A settler is ready near Karak, I didn't move it, so the next player can choose our next city... probably in the south peninsula.
