Moaning for No Reason

The core setting is that the main and secondary worlds are intertwined, with the main world being reality (narrated in a diary-like form and multiple perspectives), and the secondary world being ancient times (third-person narrative). The experiences of the main world will be mapped to the sleep dreams of the secondary world, and the secondary world includes Chinese history (main) and world history (auxiliary); there is an emotional experience setting, and "sorrow, sadness, joy, anger, and joy" are respectively associated with five dynasties/periods. After the death of the secondary world, returning to the main world requires Wu Bing to understand life (other conditions need to be improved) to return stably. Looking forward to it
