I'm so angry that I can't read free e-books even though I'm jailbroken. Ask for the Great God's tutorial

After Apple jailbreak, it could access free e-books through some third-party software. For example, you can use an app like iBooks or a smartphone to read an e-book. After installing these applications, you can access them through jailbroken Apple devices and use their built-in browser to browse e-books. However, it should be noted that there may be security risks in the Apple device after jailbreaking. Therefore, it is recommended to operate with caution and follow Apple's regulations and recommendations. If you need help installing or using these applications, you can check Apple's official documents or seek help from other professionals.
