There weren't many bricks and tiles on each carriage. Otherwise, they would be too heavy and the horses wouldn't be able to pull them.
Moreover, the carriage had to go back and forth several times a day. If the horses were tired, there would be no horses to pull the carriage the next day.
Jiang Yue naturally thought of the big trucks in her original world. If there were such big trucks, they could probably transport all the bricks and tiles in one morning. They would not need to use that much energy bringing the goods back and forth.
It was no wonder that bricks and tiles were so expensive. It was too time-consuming and laborious.
