After entering the ancient book shop, Zhou Yu began to browse around.
Soon, he found some records about the customs and culture of the Heavenly Origin World.
To avoid attracting attention, Zhou Yu picked out all the ancient books related to the customs and culture of the Heavenly Origin World, and at the same time, he also bought some ancient books about Pill Medicine and Formation.
In addition, he casually grabbed a whole bunch of miscellaneous ancient books.
Then, he used the token from the Skywind Mercenary Corps given by Liu Tang to check out and left.
The reason Zhou Yu did this was also to obscure others' scrutiny.
In this way, it would be difficult for others to discover any clues from what kind of ancient books he bought.
Although the possibility is very small, almost no one would pay attention to what Zhou Yu bought.
However, just in case.
After all, this is a strange place.
