Heavenly Spirit Boats, also known as flying boats, were the primary means by which Great Zhou armies marched.
Otherwise, how could a group of soldiers whose cultivation had not yet reached the Dao Entry Realm undertake long-distance marches relying on their own ability to fly?
Leaving aside anything else, traveling from North Sea Commandery to the nearest Ancient Teleportation Array in the Marquisate of Haiyuan would take at least a month.
As for the various hidden dangers brought by the collective flight of more than two hundred thousand troops, even the many complicated possibilities of midair collisions, none of it could be predicted.
But one thing was certain: once it happened, it would cause utter chaos.
Although these Pulse Forging Realm and Palace Opening Realm soldiers were relatively weak compared to top commanders, their flying speed was still quite fast.

Moreover, an army's marching speed did not depend on its fastest person, nor on the speed of most soldiers. It depended on its slowest soldier.
Therefore, flying boats were the best way for a large army to advance.
