"If we still can't meet the demand, we can next work on increasing the speed of the vehicles. As long as this aspect is improved, it can also alleviate the pressure on the tunnel."
The Crown Princess fully demonstrated her wit, turning her head to come up with several feasible strategies to relieve pressure, much more time- and effort-saving than Gaven's proposal to dig a new tunnel.
"Changing the mode of transportation is indeed a very feasible strategy." Gaven agreed, "Later on, we could adopt a method of pulling rail vehicles for short-distance rapid transit."
Beast-drawn carts, even if faster, have relatively limited speed, far less effective than mechanical power in excavation, and this mechanical power does not solely refer to steam boilers and combustion engines but also includes magical power. Among other things, the Goblin Sorcerers in the Three Rivers Region are researching a bona fide Magic Furnace powered by Negative Energy.
