After modifying the White Tiger Blade, Wang Daoyuan did not continue modifying the other four Natal Artifacts.
The White Tiger Blade alone had consumed five years. To transform the Five Elements Subduing Demon Seal into longswords, each artifact would require major alterations.
The fusion artifact inscriptions would also need drastic changes. Completing the entire improvement without thirty or forty years was nothing but wishful thinking.
Wang Daoyuan did not want to waste too much more effort either. The White Tiger Blade's current power was already enough to contend with any opponent below the Nascent Soul realm.
As long as he did not encounter Nascent Soul-level combat power, he would not be defeated.
The gap in combat power between Nascent Soul and Half-step Nascent Soul was a chasm that could not be crossed. Even if he modified the Yinglong Demon Slaying Sword, it would not be a match for a Nascent Soul cultivator.
At most, he would be able to exchange a few more moves with a Nascent Soul Cultivator.
Before breaking through to Nascent Soul, modifying these things held little meaning.
It would be better to first head to the Seven Stars Sea Cultivation World. There had once been Deity Transformation Cultivators there, so its various inheritances ought to be more sophisticated as well.
Stones from other hills could be used to polish jade.
Once he broke through to Nascent Soul, his understanding of artifact refining would surely rise to another level.
After absorbing some of Seven Stars Sea's inheritances, the Natal Artifacts he modified would become even stronger.
It was also time to deal with other matters. There were still quite a few spiritual plants in the Spirit Pearl Space that needed tending.
That Seven-Leaf Ghost Face Flower from back then had long since gone to seed and withered.
