Ye Lin calmed his mind and Qi, extending his Divine Soul into Evil Slayer, using his powerful Divine Soul energy to begin clearing the Demonic Soul's memories.
After the previous refinement, the Demonic Soul had become incredibly weak, so it could only watch as Ye Lin cleared its memories, unable to do anything.
It was undoubtedly true that the Demonic Soul's memories contained many valuable things.
Cultivators possess a Spell called Soul Search, which allows them to directly view and even plunder others' memories.
However, Ye Lin did not do this to the Demonic Soul. Soul Search is a suppressive Spell specifically used by high-rank Cultivators against low-rank Cultivators.
Although the Demonic Soul was currently only a remnant, its Peak strength was at least that of a True Monarch, so he dared not act rashly.
If he were to capsize in a ditch, it would be disastrous, so Ye Lin did not use Soul Search at all; he simply cleared the memories directly.
The entire process lasted a full half an hour, and after half an hour, beads of sweat appeared densely on Ye Lin's forehead.
This was a massive undertaking, even for him now.
Fortunately, everything proceeded as he had envisioned; the Demonic Soul's memories had been completely cleared.
Subsequently, Evil Slayer's Artifact Spirit began to merge with the Demonic Soul, and black-purple patterns slowly started to appear on Evil Slayer's surface, as if it were evolving in an unknown direction.
Ye Lin watched quietly. He had done everything he needed to do, and now he could only rely on Evil Slayer.
The reason he valued Evil Slayer so much was because it was his first weapon. Ye Lin was a nostalgic person; otherwise, he would not have spent a fortune to upgrade Evil Slayer to an Earth Rank Spiritual Artifact back then.
As more and more black-purple patterns appeared on Evil Slayer's surface, the connection between Ye Lin and Evil Slayer deepened.
This process took a full hour, and Evil Slayer had completed its evolution. At this moment, Evil Slayer rapidly rotated around Ye Lin.
Inside Evil Slayer, a tall, black-purple giant with terrifying patterns all over its body was looking at Ye Lin, its eyes filled with respect.
Looking at Evil Slayer now, its sword body was entwined with black-purple patterns, and black-purple mist surrounded the longsword, making it resemble a Demonic Weapon.
Even the Artifact Spirit's appearance was that of a demon.
After all, this Artifact Spirit was violently nurtured by him, and Evil Slayer had evolved into a Demonic Weapon.
"Master."
A voice emanated from Evil Slayer, clearly the voice of its Artifact Spirit.
The next moment, Ye Lin felt relieved.
Who cares? A Demonic Weapon is a Demonic Weapon, as long as he, Ye Lin, can suppress it.
"This harvest was good. Let's go."
Ye Lin nodded with satisfaction, and Evil Slayer transformed into a string of sword pills wrapped around Ye Lin's arm. Ye Lin then quickly left the underground cavern.
Upon reaching the surface, Stealing Heaven was quietly sitting on the flying boat, waiting for Ye Lin.
"You're out?"
Noticing Ye Lin's arrival, Stealing Heaven opened his eyes and looked at Ye Lin.
"Yes, let's go. We need to hurry to the next location."
Ye Lin nodded, stepped onto the flying boat, and then the flying boat transformed into a streak of light, flying towards the distance.
While Ye Lin was busy, on the other side, in Divine Sword City, a large square was filled with people.
In the center of the square, a young man sat quietly on the ground, surrounded by dense Sword Intent.
