Jiang Yifan's imagination was indeed rich, he thought that on the vast lands of the Great Xia Dynasty, tracks would sprout like bamboo shoots after a rain, crisscrossing randomly across the ground, to the point where even regular horse and ox carts would find it impossible to traverse the roads.
Ye Xinyan understood Jiang Yifan's concerns, pondering that the minds of ancient people were all spent on scheming against each other, "Rail traffic is different from others, if it really were to be built by the private sector, it might not be a bad thing. If it's short-distance and located in a bustling area, then report to the court, where to build, how long to construct, the court will approve or reject based on the situation. What's there to worry about?"
Jiang Yifan was still not entirely cheerful, replying, "The emperor is high, and the heavens are far away, I'm afraid it's not as simple as you say once this door is opened."
