Survival
Hua Wan'er was a bit surprised when Jun Tianyun asked that. " Well, It's made by Spatial Crystal. It's a rare crystal that's found in… rare places."
She paused as if she was hesitant to tell the source. " However, With perfect refining and inscribing a Space Expansion rune on it, we can make a Spartial Ring."
" However, It doesn't contain infinite space, nor is completely weightless." She added. " At most, It can store ten kilograms of materials and its space is five cubic meters."
" Not to mention, It's very fragile. One wrong move and all the contents inside will destroy. Our sect only has a dozen of the spatial rings."
Jun Tianyun was surprised when he heard that. Jun Tianyun looked at the spatial ring as he silently copied it and simulated a version in God's Space.
" So, Do you know how these beasts are graded?" Jun Tianyun suddenly asked. Hua Wan'er was startled as she nodded.
