His obsession with the Innate Spirit Treasure Secret Technique was also related to the bottleneck he had encountered in the Innate Restriction Method over the past three years.
Over the past three years, he had not neglected trying to master more profound Innate Restriction Methods, hoping to add more Innate Restrictions to his existing Emperor Artifacts, such as the Chaos Profound Bell and Mountain Splitting Sword, and increase their power.
Yet every attempt had ended in failure.
Aside from the fact that his current Emperor Materials could not withstand more Innate Restrictions, the crucial bottleneck lay in the strength of his own divine soul.
Engraving Innate Restrictions placed extremely high demands on the divine soul's strength and precision. With each additional restriction, the divine soul expenditure increased geometrically.
Although Lin Yi's divine soul far surpassed those of cultivators at the same level, he was still unable to forcibly engrave more than nine Innate Restrictions onto already-formed Emperor Artifacts. Every attempt caused a tearing pain in his divine soul, and he simply could not hold on.
For that very reason, Lin Yi had placed all his hopes on creating the Primordial World this time.
He hoped to use the unmatched, majestic power born at the creation of a world to break the shackles of conventional artifact forging, allowing the Innate Spirit Treasure being nurtured to be born with more than nine Innate Restrictions.
Ideally, it would reach eighteen, thirty-two, or even more, becoming an existence far beyond top-tier Emperor Artifacts and capable of rivaling a Dao Artifact.
Finally, before formally creating his inner world, Lin Yi raised a hand and swept it through the air. A colossal object materialized as a projection and crashed down upon the central mountain peak of the Spirit Vine World.
It was the Dragon God Remains
