บท 705: Chapter 678: Attack

Xu Fan looked at the spirit treasure in front of him that contained the Great Dao of Time, falling into deep thought.

He was pondering how many spirit treasures he would need to ascend to the Mahayana cultivation level.

"Grapes, can you tell me what the most common spirit treasure is that contains the Great Dao of Time in the cultivation world?" Xu Fan asked.

A small transparent crystal stone, about the size of a ping-pong ball, appeared in front of Xu Fan.

"The Space-Time Crystal, which is most prone to form in areas of unstable space. To condense this small piece of Space-Time Crystal would take hundreds of thousands of years," Grape explained.

"How long can this small space-time crystal accelerate time?" Xu Fan asked.

"This small piece can accelerate time for 8-10 years."

Xu Fan picked up this small piece of crystal stone, studying it carefully.

Then he placed it back within the pile of time spirit treasures.
