After leaving this place, Gu Chen went to the merit hall and retrieved the weapon he had previously exchanged, a long sword called Red Refinement.
This sword was about three feet long, and the blade emitted a red glow. It was forged through repeated smelting with a type of ore called Red Refinement Steel, making it a lower-grade treasure weapon.
Treasure weapons surpassed common weapons and were categorized into upper, middle, and lower grades. Gu Chen's previous sword was only a sharp weapon made of ordinary iron and was far from being a treasure weapon.
Even an ordinary person wielding a treasure weapon could easily kill a martial artist at the pinnacle of the Body Refining Realm, and even a Blood Refining Realm martial artist dared not face it head-on, showing the power of a treasure weapon.
What some Jianghu people referred to as magical weapons were actually treasure weapons.
