Traveling Through the Book: Sauron Travels to the Point Where the Ghost Is Destroyed, and Wu Mei Breaks His Defense.

[System + Gu Yina + single female protagonist + fan] During the confrontation with the big bear, Sauron couldn't bear the pain and fainted. When he woke up, he found himself on an unknown mountain with wisteria flowers on the side. The prompt sounded in Sauron's ears: Ding, bind the Great Swordsman System. After completing the task, you can return to the original world and resurrect Kuina.
