The connection between the first, second, and third parts of the Heavenly Demon God Tan mainly included the following points: The first and second parts were both the main story of the Heavenly Demon God Tan. The two were inseparable. In the first book, the protagonist Ares grew up to become a powerful magician and showed his strength in the battle against evil forces. In the second movie, Ares continued to fight against the evil forces and joined an organization to start an even more intense battle. The third part was based on the first and second parts and mainly talked about the challenges and adventures that Ares and his companions encountered during their journey. Different from the first and second films, there were some new characters and more complicated plots in the third film. There were also some connections between the storylines of the first, second and third chapters. For example, at the end of the second movie, Ares and his companions found a mysterious portal and decided to go there for more adventures. This portal was also similar to the portal in the first movie, so it could be said that the stories of the first, second, and third movies were related. The connection between the first, second and third parts of the Heavenly Demon God Tan was very close. Together, they constituted a complete story world.
