I Have Already Become an Immortal, and You Tell Me About the Holy Light?

Jiang Lin, the scroll king in the world of cultivation, was proficient in talismans and alchemy, but he was plotted against by a man and a woman who drained his cultivation and died.

Jiang Lin weighed the low-grade spiritual stone named "Magic Crystal" in his hand, then looked at the primitive world that was full of "treasures of heaven and earth" for him, and showed a kind smile.
