The black figure let out an enraged roar, and then several black-purple streaks of light suddenly emerged from around the void, rapidly assailing Ye Lin.
The next moment, a golden barrier erupted from within Ye Lin, blocking all of these streaks of light.
"A Soul Transformation Middle Stage attack? Is this your final trump card? Heh."
Ye Lin sneered, then increased the intensity of his actions, as he now intended to directly refine this black mist.
"Damn it, I held sway over the Ancient Era, yet I never expected to fall into your hands now? Damn it, damn it!"
"If I were at my peak, how could I be so aggrieved?"
The black figure endured the excruciating pain, roaring in indignation.
If he had come here at his peak, he could have blown Ye Lin to death with a single breath, but alas, he was now merely a wisp of a remnant Divine Soul.
If his treasure hadn't experienced some issues these past few days, how could Ye Lin have discovered him?
Damn it, where did Ye Lin come from? His treasure just happened to have problems these past few days, and Ye Lin just happened to arrive.
Why, why is there such a coincidence in this world?
At this point, he fell into deep self-doubt.
He had relied on this treasure to evade the investigations of various major powers for hundreds, even thousands of years, yet just as it had some issues these past few days, Ye Lin arrived.
Why is there such a coincidence under heaven?
Just five minutes later, the black figure, who had been so arrogant moments ago, was now on his last breath, having completely transformed into a pool of black liquid.
This was the purest Divine Soul power, and the next moment, Ye Lin took out Evil Slayer.
"No... don't, kill me, if you have the guts, kill me."
Upon seeing Ye Lin take out Evil Slayer, the black figure's face was filled with terror; he now knew what Ye Lin intended to do.
Ye Lin wanted to refine him alive, to use his Divine Soul power to nurture a Spiritual Artifact spirit.
However, Ye Lin completely disregarded the black figure's pleas and directly placed him inside Evil Slayer.
Although there was a spirit within Evil Slayer at this time, it was very weak, so everything else required his meticulous operation.
After all the Divine Soul power was integrated into Evil Slayer, the Spiritual Artifact spirit within Evil Slayer fell into a frenzied rage, rapidly devouring this Divine Soul power to strengthen itself.
"It's the most crucial moment."
At this moment, Ye Lin's expression was extremely solemn, without the slightest relaxation.
What he needed to do now was to completely erase the memories of this evil demon's Divine Soul, and then allow the Spiritual Artifact spirit to take residence, at which point, Evil Slayer's Spiritual Artifact spirit would develop sentience.
This process was extremely perilous; if the memories were not completely eliminated, and this evil demon's consciousness retaliated and devoured the Spiritual Artifact spirit, then it would be over.
If it came to that, all Ye Lin could do was obliterate the Spiritual Artifact spirit, and without a Spiritual Artifact spirit, Evil Slayer would be useless unless a high-level Artifact Refiner was invited to re-endow it with a spirit.
The potential of the Spiritual Artifact spirit directly determined the most obvious indicator of whether this weapon could grow to Heaven Rank.
If it were re-endowed with a spirit, then Evil Slayer would ultimately only become an Earth Rank Spiritual Artifact.
Even if it were re-refined using various top-tier Materials, it would be impossible to elevate it to the Heaven Rank level.
And if a high-level Artifact Refiner were to directly forge it into a Heaven Rank weapon, it would no longer be Evil Slayer, but an unfamiliar sword.
Even an ordinary sword used by a Mortal for decades, even if this ordinary sword had no Spiritual Artifact spirit and was just an iron tool, that Mortal would still consider this weapon to be of great significance, and no other weapon, no matter how exquisite, could compare.
This was a special bond between a Cultivator and his Spiritual Artifact.
