Out of the five basic buildings required for a grade 3 county, the brothel and the college had already been built. He still needed the clock tower, the Confucius Temple, and the Military Temple.
It had to be said that the brothel in the game centered around the entertainment value of the civil servants. The girls there were selling their art and not their bodies, so they were mostly singers and dancers.
For the building blueprints for grade 3 counties, each of them was sold for 1000 gold. As the market had already removed the function of buying blueprints, Ouyang Shuo had no choice but to send three thousand gold over to little aunt and ask her to purchase it for him. Then, she could send it over to him to save the 10% sales tax.
At this stage, basic buildings stopped being the bottleneck that prevented territories from upgrading.
While Ouyang Shuo was upgrading, he still paid attention to Di Chen and the others.
