The destruction of a corrupt dynasty is like the process of a parasite: constantly feeding on the host's nutrients, yet still maintaining superficial operation. When the system gradually fails like an immune system, problems accumulate but cannot be repaired; when internal contradictions approach a critical point, rebellions, uprisings, power struggles, and economic collapses erupt one after another, and the entire structure disintegrates. By this point, external shocks such as war or natural disasters are just the final blow; they are not the cause, only the moment it falls.
