[Additional Reward: Yuanying City (a city without any living beings)]
[Additional Reward: Demon Suppression Formation Diagram (this formation is enough to trap deity stage Immortal cultivators)]
[Additional Reward: Aura of a King (a kind of spirit that Fu Shuangni has cultivated over the years)]
"Spirit stone reward, as expected."
After seeing the four additional rewards, Bai Yi was not surprised by the appearance of spirit stones, because in the later stages of Great Yan City, it was getting stronger and stronger. They had a huge amount of spirit stones.
To be honest, spirit stones were not particularly useful to Bai Yi.
That was because he almost did not need spirit stones to aid his cultivation.
In other words...
To him, spirit stones could be used as currency to trade with some Immortal cultivators, or as one of the materials to set up an array formation when he had some free time.
Other than that...
