In the secret chamber, Lin Tianming held a jade slip in his hands, pondering deeply after consulting it.
Today, he had purposely bought a large number of books from various shops in the marketplace, including some that recorded the wonders of heaven and earth, but he still hadn't found any references related to the Mysterious Moon Order.
Lin Tianming speculated that it was very likely the key to some secret realm or the token of a large family or sect.
In the vast Cultivation World, there are many dangerous places and secret realms, which contain a multitude of treasures but also numerous prohibitions and formation protections, all extremely powerful. Usually, special tokens or certain items are needed to enter.
Alternatively, when a secret realm emerges into the world, its prohibitions might be weakened, making entry much safer.
If one does not have the specific items and attempts to force their way in, it's very easy to be attacked by the prohibitions, risking loss of life.
