On the fourth morning,
Xu Nian was still refining artifacts after practicing for a full two days and two nights, and by now Xu Nian had essentially mastered the entire process.
"Buzz!"
Xu Nian, with a thought, retrieved a head-sized fireball from the roaring flames within the Copper Tripod.
With another thought, a piece of scrap iron floated in front of him.
Xu Nian controlled the fireball with his Spiritual Sense to envelop the scrap iron, quickly melting it into molten iron.
The fire was ordinary flame and the iron was ordinary iron, but this process required manipulation with Spiritual Sense, otherwise, it would take a long time to melt.
Next was the shaping step.
Xu Nian controlled the molten iron with his Spiritual Sense, gradually shaping it into a sword form.
He then controlled water to pour over the iron sword, casting it into an actual Sword Embryo.
After completing all this, only one step remained—Hammering, or in other terms, forging.
