"Using this treasure to grow spirit herbs is truly the most efficient method, but you can also use it in the mines to increase the production of spirit stones.
But there is a limitation to this. It cannot be used for cultivation. If anyone enters the area affected by the treasure, their perception is dulled. It's similar to the mist outside, but in a different manner.
Second, even if the time is accelerated, it doesn't mean you will receive ten years' worth of spirit qi in mere seconds. After all, It did not provide you with spirit qi, and nature's qi will enter the area in the same proportion as before.

So even for these spirit herbs to grow, you have to provide enough spirit stones to the soil to maintain their growth. And believe me, it's a lot.
