The night passed without incident.
Xu Ping'an spent almost the entire night immersed in cultivation.
Overnight, Xu Ping'an devoured a large amount of Sixth Rank Monster Cores and began to strengthen his True Yuan.
Upon completing the First Transformation, Xu Ping'an started undergoing the Second Transformation.
By the end of the night, he had only completed the transformation of five hundred strands of True Yuan.
As for the Thunder Attribute True Yuan, he also began the First Transformation, but likewise, he only completed five hundred strands.
Simultaneously with the True Yuan transformation, Xu Ping'an was also utilizing Indestructible Thunder Bone Tempering.
Now his Bone Tempering had reached the Sixth Rank Peak, and the seventh Bone Tempering was nearly completed.
Once finished, Xu Ping'an would be able to break through to the Seventh Rank.
It must be said that after his Soul Realm had grown stronger, his speed of cultivation had increased greatly.
