Chapter 423: Chapter 414: Dong'er, I Have Arrived

Atop the main body of the Octagon Frozen Grass, the diamond-shaped octagonal crystal fully appeared, exuding a pure chill.

In Huo Yuhao's Sea of Spirit, the Skydream Ice Silkworm exclaimed, "Wow, the purity and concentration of the ice element contained here far exceed the Ten-Thousand-Year Ice Marrow that I absorbed at the beginning. This must be the essence of the Extreme Cold Ice Spring that it has refined over ten thousand years."

The somewhat weakened voice of the Octagon Frozen Grass spoke up, "Since I'm going with you, there's no use in keeping this. This is the Octagonal Profound Ice Crystal that I cultivated over ten thousand years. Take it. Carrying it with you will speed up your cultivation, and if it's set into a weapon, it can endow any metal with the might of Ultimate Ice. The essence of my hundred-thousand-year cultivation is all here."
