It was such a sudden change that Su Bai was totally shocked.
Luckily, he was well-experienced and wouldn't be affected too much by such stuff. After the surprise, when he saw their smooth practice turn into an embarrassing orgy, he calmed down and noticed marks on those people's foreheads like masses of dark clouds. Those marks weren't there before, Su Bai was sure about that.
Walking through those people's mirage was like walking into a five-dimension film; it felt real but became nothing to enjoy after a little while. Especially, these Taoist ladies looked really plain without their elegant Taoist clothes, probably because they were on a light diet and carried out fasting from time to time.
Even after Su Bai had passed this small pavilion, their orgy was still going on. Actually, those man could not last very long. Su Bai had noticed that they were young and lacking in sexual experience due to their isolated life in the mountains, and therefore would always come really quickly.
