One year later, on the underground spirit island beneath Little Plum Mountain.
Li Ping abruptly opened his eyes, and two beams of divine light seemed to shoot from them.
After breaking through to second-tier body refinement, he discovered that the Nine Tribulations True Spirit Sacred Canon, a mysterious cultivation method of unknown origins, could extend his lifespan.
Within those additional years, he might be able to cultivate to the peak of core formation and attempt nascent soul formation without relying on pills.
Thus, for a fifty-percent chance of successful nascent soul formation, he unhesitatingly decided to make the Marsh Water Life-Nourishing Art his primary cultivation method.
For the moment, however, he was still cultivating the Nine Tribulations True Spirit Sacred Canon for his second golden core.
His second golden core would encounter no bottlenecks before core formation. Even if he continuously consumed spirit herbs, there would be no risk of destabilizing his foundation, allowing him to reach the third tribulation of the Nine Tribulations True Spirit Sacred Canon in seventeen or eighteen years.
Once that happened, he would be able to see the third-tier body refinement portion of the method. Then he could relegate his second golden core's cultivation to a secondary position and focus on the Marsh Water Life-Nourishing Art.
This time, however, he had stopped cultivating not because of his cultivation itself, but because the purple-patterned wood planted on Gray Island had reached a thousand years of age.
Thousand-year-old purple-patterned wood had already reached third-tier lower-grade.
If he continued nurturing it, it would only reach third-tier middle-grade at two thousand years.
After reaching third-tier top-grade at five thousand years, it would stop growing altogether.
They were all third-tier materials, and there was little difference between third-tier lower-grade and third-tier middle-grade. Spending another thousand years on that was not
