The crafting of the War Flying Ship is similar to the refining of ordinary magical treasures,
with the only difference being that magical treasures are crafted in one go, whereas the War Flying Ship requires its individual components to be refined first,
and then eventually assembled together,
in a way, it can also be considered a combination magical treasure.
The Tier Four Flying Ship that Zhou Xun and his team aimed to create,
has its core as the keel running through the entire ship, which must be refined using Tier Four materials, and for this step, Master Iron Mountain, a Tier Four Refiner, must personally complete the task,
While other parts of the ship, such as the hull and deck, can be made with Tier Two and Three Spirit Woods, and these parts can be completed by ordinary Tier Two and Three Refiners.
