Based on what he had learned during his time in Teyvat, aerial transportation was the best option. Building roads here, especially highways connecting different nations, was simply far too troublesome.

Anti-gravity devices were nothing to Shen Fei, but most ordinary people could not afford them. It was a matter of cost. For example, Shen Fei could casually give an ordinary person an airplane, but what would happen then? That person simply could not afford to
