I remember there was an article in children's literature about a general who met a pool city and a god in a game. He lost and died of depression.

The theme of this story might be ancient wars, immortals, generals, pool cities, etc. According to the described plot, one could further imagine the image of an imaginative, brave and fearless general and a mysterious and powerful immortal. The general thought that he would win before the war, but in the end, he lost the war, which led to depression and depression. This could be a story about war, human nature, psychology, and other topics. The general's death could be a key plot turning point that could reveal the general's emotional changes and why he lost the war. Some elements could be added to the story, such as the general's wife, son, friends, etc. They might experience a series of sad events after the general's death, but they also had to face it all with strength. The story could revolve around the general's expedition, war, victory, defeat, psychology, and other aspects. At the same time, some myths, legends, and mysterious elements could be added to enhance the story's legibility and interest.
