"Black Crystal is a type of Crystal Stone that assists in breakthroughs! Extremely expensive! If you ingest Black Crystal during a breakthrough, the probability of enhancing your breakthrough level can increase by several times!"
Increase several times?
Upon hearing this, a trace of joy flashed across Ye Feng's face!
Previously, Ye Feng had asked Kay how long it would take to break through from Xuan Master to Xuan Saint!
At the time, Kay had said it might take decades!
Now with this Black Crystal, can it significantly shorten the time?
Ye Feng paused for a moment, then asked:
"With this Black Crystal, can the breakthrough time be accelerated?"
"Yes!"
Kay nodded, smiled and said:
"If you have Black Crystal, you can try to break through now, and the chances should be quite big!"
"That's great!"
A streak of excitement flashed across Ye Feng's face!
"Beep Beep!"
