Bus!
So this is the means of transport used for getting around in Konoha!
Heitu curiously examined the vehicle, which looked similar to a train but was much shorter, and its four metal wheels ran on a white track.
It appeared as if the white track would rise from the ground ahead as the vehicle moved forward, and it would disappear behind the vehicle after it passed.
This must also be mycelium, right?
Thinking this, Heitu felt a curiosity about the Hokage of Konoha Village, "Could it be that the Hokage possesses a Kekkei Genkai that can control mycelium?"
Perhaps the entire Konoha Village underground is filled with mycelium, which greatly facilitates the movement of these vehicles.
In the Ninja world, such railcars are highly impractical since a single Earth Release Ninjutsu could destroy the tracks, essentially inviting others to dismantle them.
However, using mycelium as tracks, this issue could be resolved.
But this type of vehicle is probably popular only inside Konoha.
