The Red Flame Sword was entirely crimson, forged from a special type of Red Flame True Iron, and measured seven feet long—it was unmistakably a heavy sword.
"This material used to forge the Red Flame Sword is indeed good, but the forging technique is too crude," Chu Fengmian remarked in a low voice after glancing at the Red Flame Sword.
The material for crafting the Red Flame Sword, the Red Flame True Iron, was a kind of celestial black metal naturally imbued with extremely powerful fire Spiritual Power, making it the perfect material for forging fire-type Spiritual Artifacts.
Given to some Artifact Refining Grandmasters, the Red Flame True Iron could potentially elevate an artifact to the level of a heavenly-class Spiritual Artifact or, at the very least, effortlessly create a top-tier earth-class Spiritual Artifact.
However, the quality of this Red Flame Sword was merely a mid-level earth-class, no wonder Chu Fengmian felt that the forging of this sword was exceedingly crude.
It could even be considered a waste of heavenly materials.
There were seven patterns engraved on it, but to Chu Fengmian, these patterns were equally crude.
If it were properly refined, the power of this Red Flame Sword could be many times greater than it was now.
"Although this Spiritual Artifact has already taken shape and cannot be reforged, the Array on it can still be re-engraved," Chu Fengmian murmured quietly to himself, then suddenly walked over and grabbed the Red Flame Sword.
The moment Chu Fengmian took the Red Flame Sword, a surge of flames burst forth, scorching his hand.
The Red Flame Sword already possessed a spirit; unless it was subdued and its master acquired, control over it could not be gained.
"Just a Spiritual Artifact and it dares to resist Chu?" Chu Fengmian frowned, his body’s Spiritual Power erupted entirely, filling him with formidable dragon might.
Dragon Might was an exceedingly domineering type of pressure; even the Red Flame Sword, upon sensing Chu Fengmian’s dragon might, started to retract.
How could a mere Spiritual Artifact dare to defy the majesty of an ancient war dragon?
The flames on its body immediately extinguished, allowing Chu Fengmian to take control.
Chu Fengmian shouted lowly, and a surge of Spiritual Power charged directly at the Red Flame Sword, which also tried to resist. However, in the face of Chu Fengmian’s dragon might, it could only give up.
Allowing Chu Fengmian’s Spiritual Power to shatter all seven patterns on the Red Flame Sword.
"I wonder how many patterns I can engrave with my current strength," Chu Fengmian mused to himself. In his past life, as an Alchemy Grandmaster, he had learned to engrave patterns.
Back then, Chu Fengmian, who possessed no Spiritual Power, could rely on the power of the Pill Furnace to practice Alchemy, but he was unable to engrave patterns.
This was actually the first time Chu Fengmian was truly engraving patterns himself, and even he was unsure of the outcome.
"All patterns will be power-enhancing; the heavy sword lacks sharpness, but its strength must be formidable!"
Unlike light swords, which rely on skill in combat, the heavy sword is swung with hardly any finesse but rather involves pure power clashes.
To overwhelm the enemy with sheer force, the strength of the heavy sword must be substantial.
While engraving patterns on Spiritual Artifacts, they typically choose patterns that reduce the consumption of the artifact’s Spiritual Power, allowing the user to lessen their own Spiritual Power expenditure.
However, this would also reduce the inclusion of other types of patterns, such as with an earth-class Spiritual Artifact only being able to incorporate up to nine patterns at full capacity.
This results in a loss of some power, but it remains crucial for countless Spiritual Masters.
But for Chu Fengmian, there was no significance at all. He possessed the Divine Veins, with infinite Spiritual Power, and, to him, inscriptions that reduced the consumption of Spiritual Power were utterly meaningless.
He now intended to inscribe only strength-enhancing patterns, aiming to make the Red Flame Sword even more powerful.
In his mind, Chu Fengmian silently chanted, and a wave of Spiritual Power split and in front of him, coalesced into patterns that responded to his will.
Those three patterns then charged towards the Red Flame Sword.
They were forcefully inscribed onto the body of the Red Flame Sword.
Once the three patterns were added, Chu Fengmian immediately felt that the power held by the Red Flame Sword in his hands was now 50% greater than before.
The first three patterns were easily inscribed, which slowly built up some confidence in Chu Fengmian’s heart.
Three patterns wouldn’t suffice for Chu Fengmian; his sword had to be tremendously powerful to truly match him.
A stream of Spiritual Power gently floated out and formed another three patterns, all meant to enhance strength.
Again, he directed them towards the Red Flame Sword.
This time, the Red Flame Sword began showing some resistance. If the inscriptions weren’t backed by absolute skill and sufficient power, they would be quickly repelled.
"Let me inscribe them!"
Chu Fengmian roared, his Spiritual Power fully bursting forth. The three patterns were firmly pressed onto the Red Flame Sword, and soon Chu Fengmian saw them permanently inscribed onto it.
Now six patterns had been inscribed, and the current strength of the Red Flame Sword had greatly surpassed that of the sword before Chu Fengmian re-refined it.
Although the earlier Red Flame Sword had seven patterns, those were quite mixed in nature, whereas now, all six were devoted to enhancing strength.
Therefore, in terms of power, it was indeed much stronger than the previous Red Flame Sword.
Such Artifact Refining could likely be endured by no one else but Chu Fengmian himself, letting an ordinary Martial Artist wield this Red Flame Sword would likely result in their Spiritual Power being completely depleted after just a few strikes.
With six patterns, the power of the Red Flame Sword was already commendable.
However, this was far from enough to satisfy Chu Fengmian. He aimed to inscribe a total of nine patterns, and when all nine were simultaneously inscribed, their interactive forces would be at least twice as strong as the current six.
"Continue! Condense!"
Another set of three patterns coalesced from the air, this trio of patterns also forming.
Chu Fengmian focused his mind, and those three patterns once more surged toward the Red Flame Sword to be imprinted.
"With blood as the seal! Dragon Sacrifice Swordsmanship!"
The moment the three patterns struck out, Chu Fengmian also used the Sword Edge to slice his finger.
A drop of golden blood fell into the Red Flame Sword, immediately setting the three patterns in place.
The Sword Sacrifice Technique, the last method Chu Fengmian used, was indeed the most mysterious technique in swordsmanship, the Sword Sacrifice Technique.
