At home, she always heard the old man say 'Mystic Gate Shield'(I don't know if it's these words). What exactly was the Mystic Gate Shield? Is it superstition or science?
The Qimen Shield was a fictional concept that usually appeared in novels, movies, television dramas, and other fictional works. It could be a formation, spell, skill, or weapon that could resist other unknown forces. However, in real life, the Mystic Gate Shield did not exist. It could be a fictional concept used to increase the plot and complexity of the story without real scientific basis. Therefore, we cannot regard it as superstition or science. In fictional works, the Qimen Shield may be a fictional concept created to increase the plot and complexity, but it should exist based on the needs of the story. In real life, we should understand and explore the world with a scientific attitude instead of blindly believing in fictional concepts.
