In the comics and novels of God Save the People, what is the psychic password of Huacheng is not given, because his psychic password is not an ordinary password, and he does not need to contact other people in the gathering spirit array. He only touches Xie Liu alone. When Xie Liu knew his psychic password, he couldn't believe it and asked himself if he was mistaken. It can be seen from the side that his psychic password must be related to thank you, and everyone guessed that it was my husband Saburo. There are actually three kinds of guesses. The first kind: direct confession, similar to: "My beloved person is my husband Saburo", "My husband Saburo, my wife thanks" and so on.
The second type: Yuan Zhen's "Leaving Thinking" is the song "Once the sea was difficult for water, amber forever". Lazy looking back at flowers, half the sky is repaired, and half the sky is a gentleman. "The third kind: What Fanwai Flower City said, Liu Xie blurted out. Those two words: "You are the only God in my heart, and I will always be your most loyal believer."
The reason why it is not mentioned in the book may be that this password belongs to only the two of them, and this secret is a small interest between them, so this psychic password Huacheng only tells Xie Liu that Xie Liu will be embarrassed after listening to it.
