Age of Empires 2 HD custom campaign: Lord of the steppe (part 2)

Now we are playing second part of our adventure! We learned how to make carpet traders and now have the castle age techs. Our task is now to earn 1000 gold and bring 3 relic carts to the Turk tent. Also we need to keep bringing horses in the stable so our tribe can continue growing. Along the map we have some soldiers who are ready to join us and to the west we have Persia with its trade workshop and market. Also, we have some Chinese to the south. Maybe they have something to offer?
