In "Codename 193", "consciousness uploading", which uploads one person's consciousness to another person through experimental technology, is the key to finding the answer. Because the character can enter the brain consciousness to promote the development of the story, Xiao Lixiu studied a lot of psychology and multiple personality data when revising the script, and clarified the logic and narrative method of "consciousness uploading" in the film. The consciousness of different people in the movie was uploaded to Tony Yang's body, so he had to play the appearance of different people. Xiao Lixiu explained, "This is more complicated than a character playing multiple personality splits, because you have to understand what kind of person's personality he received the consciousness from, so that the audience knows that he has become another character." The heroine Zhang Rongrong plays a strong-willed brain science doctor with a 7-year-old child.
