Place the Vortex Gate's exit directly at Ice Song City, then your Radiant City can conduct trade with Ice Song City at zero distance. Various items that are commonplace and sell for low prices in the Elf Kingdom can all be transported to Ice Song City.
Even if Ice Song City doesn't need them, perhaps the poorly equipped Beastmen from the War Soul Clan will need them? You could use Ice Song City as a transit station for goods. Anyway, as long as the Vortex Gate is connected to Ice Song City, it will be extremely easy for you to promote the prosperity of the other side!
By that time, your reputation will soar, and buying various Ice Song Divine Artifact sets at wholesale prices will be a breeze! Moreover, Ice Song City can also connect to the Nether Sea, allowing you to transport goods there, and soon the entire Earth will revolve around you! This is high-end, advanced global networking, haha!
