Walking slowly along the Dark Court's corridor, Tang Xiu's eyes constantly swept across the stalls on both sides. His spiritual sense even enveloped all the surrounding areas, observing the items on the stalls and independent shops. He did find some Demon Stones, but after seeing the things here, he immediately realized that there were better items than Demon Stones for him, such as Demon Cores and Demon Essences.
Aside from that, there were still a lot of demon fruits. The one that amazed Tang Xiu the most was that some people were bold enough to sell demon pills.
It must be noted that anything that came from the Demon Realm had always been shunned and rejected by orthodox Immortals. Even some people with a sense of justice forcibly killed people who sold such items from the Demon Realm.
