"Exchange for top grade Spirit Stones?"
The receptionist gave Lin Chen a slightly surprised look.
Though top grade Spirit Stones have a high absorption rate of spiritual energy, their price is astronomical!
The spiritual energy contained in one top grade Spirit Stone is equivalent to about ten upper grade Spirit Stones.
However, using top grade Spirit Stones for cultivation only doubles the efficiency of upper grade Spirit Stones.
But the price?
One top grade Spirit Stone requires twenty-six upper grade Spirit Stones in exchange.
If measured in lower grade Spirit Stones, one top grade Spirit Stone requires five thousand lower grade Spirit Stones.
Yet, its spiritual energy content is only a thousand times that of a lower grade Spirit Stone.
It's equivalent to losing about five times with every exchange for a top grade Spirit Stone.
