Just as Lin Yi was about to take the ten Spirit Stones, the monk shopkeeper smiled and pulled out a jade slip. "Friend, would you like the Spirit Wood Technique? It's the best to check cultivation levels and distinguish between the strong and the weak. It's a must-have for every cultivator, only ten Spirit Stones per copy."
The Spirit Wood Technique is a spell that many cultivators possess. With a flash of spiritual light in the eyes, one can examine the opponent's cultivation level. Of course, if the opponent's cultivation level is higher than one's own, it can't be seen. However, if the spell level is high, it can break this limit.
However, no one will spend time on a small Spirit Wood Technique. It is generally sufficient just to detect the strength of cultivation.
