This is a very interesting plot that can be explored from different angles. One possibility was that the protagonist realized that the world was full of uncertainty and could not predict which would come first, tomorrow or an accident. This might involve the protagonist's discussion of his own uncertainties and fears, as well as suggestions on how to face the situation. Another possibility is that the protagonist discovers that people are always trying to predict the future but often can't accurately predict the future. This may involve suggestions on how the protagonist can help people realize the true value of uncertainty and how to make people better adapt to this uncertainty. There was also a plot where the protagonist found that he could control uncertainty and use his wisdom and skills to deal with future challenges. This might involve advice on how the protagonist learns and grows, and how to remain calm and clear in the midst of uncertainty. These are just some possible plots. You can choose one or more of them according to your preferences.
