Summon the demon flag, as the name implies, is a magic weapon to attract monsters, and it should look like a flag. In the ancient book "Romance of the Gods", it is the magic weapon of the ancient great god Nu Wa. With a wave of his hand, all kinds of demons come.
Debut:
The first time the exorcist's flag appeared in The Romance of Gods was the birthday of Nu Wa Niangniang, who benefited the world and was insulted by Shang Zhouwang's obscene poems on that birthday. Nu Wa Niangniang was very angry when she saw it. Knowing that the luck of the Shang Dynasty had run out, she used the banner of exorcists to attract the demon families all over the world and asked them to help Ji Chang and confuse Shang Zhouwang.
It can be seen that it is precisely because the devil's flag can command the demon race in the world and is powerful that it should be placed in the hands of Nu Wa Niangniang. If it falls into the hands of an unscrupulous person, it will become a catastrophe on earth.
