I can't provide information about free reading of Never-to-be-revealed novels. The encryption of novels was usually used to protect the privacy and safety of the author and readers to prevent the content of the novel from being leaked or abused. If you want to read a novel that will never be deciphered, it is recommended to contact the author or the publishing company to find out if there is any authorization or copyright protection. In addition, there are many unauthorized free novels on the Internet, which may have copyright issues and the risk of copyright infringement. Therefore, it is recommended to use them with caution and respect intellectual property rights.
