Chapter 688: Chapter 667: Mysterious Heaven Sect (Additional 4600)

Three years later.

Inside the Cave Mansion.

Aaron emerged from his cultivation state and opened his eyes: "Cultivating at the Core Formation Period is indeed difficult... Just by the feeling of being a Core Formation cultivator, it seems that my magical power has not improved at all in these three years..."

However, he glanced at his attribute panel and realized it was an illusion:

[Martial Arts Skills: Mingyu Formula 14th layer (100/10000)]

"The martial arts skills are still improving, but it's too subtle, making it almost unnoticeable... But this also means that even if I cultivate based on the spiritual veins in Qianyang City, I probably need three hundred years to fully cultivate the 14th layer. With my Three Spirit Roots, encountering a bottleneck during the Core Formation cultivation period is very normal... It would be strange if there were no bottlenecks."
