The art of "Blood Sacrifice for the Sword" had been circulated among the Nine Domains, yet for most people, it remained a profoundly mysterious matter.
To perform a blood sacrifice for the sword, to the common eye, seemed like a demonic practice.
But this art of sword sacrifice was actually the most crucial part of the ancient art of swordsmithing, where the blood sacrificed was that of the divine spirits.
The higher the quality of the sacrificial blood, the better the effect, and the more noble the blood, the better the results of the sacrifice.
Yet among noble blood, none could compare to that of an ancient war dragon, a single drop of Chu Fengmian's blood was essentially equivalent to a drop of true ancient war dragon blood.
When refining the Red Flame Sword, the edge of the sword instantly became much sharper.
Chu Fengmian picked up the Red Flame Sword; with a swing, the flames within it took on the golden color of dragon fire.
