"... This weapon is just silver lower-rank? It's a bit underwhelming."
"That is determined according to the strength of the curse attached to it, and can't be accurate. This lance is severely damaged, the internal evaluation of the Life Bank is obviously low, but the evaluation of the Bureau of Anomaly Management must be very high."
As the big cat said, ordinary professionals cannot distinguish between "upper silver" and "silver lower", they simply categorize them as black iron, brass, silver, but within the silver-tiered taboo items, differential regulations are made according to their value and risk.
This "Soul Suppressor" is the highest standard taboo seal that is "not allowed to be lent out under normal circumstances and prohibited from being moved out in non-essential times", and its weapon identity further raises its price... An excellent taboo weapon is enough to establish a battle-profession centered on it.
