Wanting to break through to the Zhiyi Boundary is a lifelong goal for many people. Some people are stuck in the Mingmu Realm their entire lives and cannot break through.
Between the Mingmu Realm and the Zhiyi Boundary is a chasm. This side of the chasm houses experts, while the other side are ordinary cultivators. That's the difference.
Reaching the Zhiyi Boundary is a lifelong pursuit for an individual, as for the Dawen Realm, it is simply unimaginable. Breaking through is as difficult as ascending to the heavens.
How could Hoshino Meigetsu have imagined that Ling Zhenfei would suddenly break through in front of him, and so quickly?
"Mingyue, I have to thank you for this. You have been a great help to me. Your true maiden body has given me substantial assistance. Without you, I wouldn't have known if I could succeed in my breakthrough."
