Priceless on the market, hard to exchange!
But now, with academic credits as currency, there are clear set prices.
Even those superior immortal implements, which are treasures from the Demonic Dao Heavenly Caves that not even the Blessed Lands and Ancient Sects dare to lay their hands on, besides the immortal implements, there are also many high-order spiritual objects and various Divine Power techniques.
These rare and sought-after treasures, which can be exchanged for relatively common magic artifacts and spiritual treasures, even if at a loss, are acceptable to the various Blessed Lands and Ancient Sects and even quite welcome.
Besides, this business might not necessarily mean a loss. Perhaps there might be a larger investment in the early stages, but as one gains more experience in artifact refining, skill becomes second nature, reducing the failure rate and the cost of sword refining directly, eventually turning losses into profits.
