"It seems the Red Sand City Lord didn't deceive me, and there's really something going on." Seeing the news, Li Xiu showed some interest in the Super Spirit Gemstone mentioned by the Red Sand City Lord.
However, if such a gemstone were to appear, the people from the City of Light would definitely not let it slide. If there was a fight for it, not only would they have to face those Demon Spirits, but also compete with the City of Light people. Even if they snatched it away, the City of Light might come knocking later; it's just a lot of trouble.
The key issue is Li Xiu doesn't even know what the Super Spirit Gemstone looks like; even if he saw it, he might not recognize it.
With so many stones in the gemstone mine, who knows which one is the Super Spirit Gemstone?
"Let's wait until the old guy finishes my Demon Armor first." To avoid causing trouble for the City of Light, creating a set of unseen Demon Armor to snatch it might be a plan.
