117 Chapter 93: The Inner Domain and the Spirit Crystal, Xu Yan Gains Insight Again - 2

```

"If there are no pills in the Inner Domain, then I'll create a pill refining method. If successful, it will definitely be a delicacy for martial artists."

Li Xuan was incredibly intrigued.

"Grandmasters and above martial artists also cultivate by directly consuming spiritual medicines, but ordinary spiritual medicines have limited effects on grandmaster-level martial artists. They mainly rely on their own bodies for cultivation.

"Alternatively, they cultivate with spirit crystals to increase the speed of condensing and refining inner Qi, but spirit crystals are rare and can only temporarily boost the condensing of martial inner Qi. They're usually not extravagantly used for cultivation.

"In most cases, spirit crystals are used after battles, when the consumption is great, to enhance the recovery speed of inner Qi."

Xie Lingfeng spoke about the cultivation of grandmaster martial artists.

"Spirit crystals?"

Xu Yan was full of curiosity.
