The reason why Yuji disappeared in the third season 01 of The Scorching Xia Na might be due to the development of the plot. In the first episode of the third season, Yuji was involved in the conspiracy of a mysterious organization for some reason and lost her memory. As the plot develops, Yuji may need to relearn and face his past. In this process, he may choose to leave or hide to protect himself and the people around him. As for the rest of the plot, it might be because the plot of the third season was more complicated and profound than the previous two. It required more understanding and thinking to fully understand. The eye-catching Xia Na series itself had a certain philosophical and sci-fi color, so the interpretation of the plot might vary from person to person. It is recommended to watch and understand the plot carefully. At the same time, you can also seek the opinions and explanations of other readers or viewers.
