Cao Zhen signed his name and entered the front courtyard of the Hidden Dragon Immortal Palace, where the decoration was very simple. There were no precious objects on display, yet the place exuded an aura of profound simplicity.
Hum! Hum!
Two powerful streams of Spiritual Energy suddenly soared into the sky, causing the air around to quiver slightly.
Cao Zhen turned around and saw to his surprise that it was Chang Tiance and Xu Ruyi at the signing area who had achieved Enlightenment!
In the path of cultivation, other than breakthroughs in Cultivation Base causing changes in the surrounding environment, only Enlightenment could cause such a phenomenon.
Enlightenment is different from breakthroughs.
Breakthroughs mean the strength has reached the next stage, and combat power has greatly increased.
Enlightenment, on the other hand, does not mean a sudden surge in power, but an increase in one's foundation... It is a deep understanding of the path of cultivation!
