In front of him, the advanced city of the Upper Origin Immortal Country, even the city walls, are forged from superior artifact refining materials, vivid and shining, even in broad daylight, exuding a hazy luster, adding a bit of grandeur to the entire city.
The vast city is beyond sight at a glance, with pavilions standing tall and houses everywhere.
As for why Lin Qian feels distressed, it's entirely because of the materials used to forge the city walls. Although they are excellent materials for artifact refining, they are not the best choice for city walls.
If such materials are added when refining armor, they can increase the toughness of Soul Armor, significantly enhancing the defense strength.
Although it is metallic Soul Ore, it is soft and tough, shining with a golden light, known as soft gold iron.
However, because of the toughness and relatively soft nature of soft gold iron, it is not suitable for forging defensive city walls at all.
