However, despite this, one can imagine the amount of metal within Small Knife's personal space.
Metal has always been the biggest bottleneck in artifact refining.
This is true even in the Four Celestial Great World.
At Little Knife Peak, spiritual artifacts like this Sword Cauldron, which are classified as large spiritual artifacts, consume even more metal.
In comparison, the reputation of the Immortal City in the Wu Feng Domain is well-known, but its quality is far inferior.
The reason is simply the lack of metal.
Although metal is not very expensive for cultivators, when the amount needed becomes excessive, the price is not something a single family can afford.
The Immortal City in the Wu Feng Domain was funded by many families pooling their resources together.
This was a necessary investment for them to establish a city in the Wu Feng Domain and have their own territory.
At this moment, a large amount of metal is being fed into the Sword Cauldron.
