There are changes from "Zi Mu Shu"
It is said that there was a family named Gu Yan in the Northern Song Dynasty's Jingshi Bieliang, and Gu Yan had a friendship with Su Hai, who lived in Zhuxian Town, saying that the seventh day of the first month of July was Su Hai's sixtieth birthday. Gu Yan rode a donkey with a birthday gift to an old friend's house to wish for a happy birthday. Because Gu Yan left relatively late. When I arrived at a place called Xidaoyu, it was dark. Just as Gu Yan was hurrying to hurry, he heard a red-faced man on horseback behind him catch up. He said to Gu Yan, "Old man, it is still too late to rush to the barren mountains and wild mountains, where is this going?" Gu Yan said that he was going to see his old friend Su Hai. The red-faced man was very surprised to hear it. Immediately said: "It's a coincidence, Su Hai is my brother-in-law, I am also going to wish for a happy birthday, you and I just happen to be walking all the way." It was a coincidence that Gu Yan listened. Just like that, the two of them chatted and walked towards Su Hai's house.
But along the way, the red-faced man always deliberately lagged behind Gu Yan. You must know that Gu Yan is riding a donkey, and the red-faced man is riding a horse. Gu Yan immediately realized that this man would not be a villain, he said that Su Hai was his brother-in-law, who knows whether it is true or not. Not only would I be afraid at this thought, but if this person was a bandit, wouldn't he be a sheep in the mouth of a tiger now? At this time, suddenly lightning and thunder sounded, and Gu Yan secretly looked at the red-faced man by the light of the lightning, only to see that the red-faced man actually put his head under the horse's body, and his feet were upside down and hanging in the air. Seeing this scene, Gu Yan almost didn't scare him to death.
At this moment, the red man opened his blood basin and spat out a cloud of black gas to hit the thunder and lightning that fell from the sky, and also spat out black gas with his tongue that was more than a mile away, Gu Yan was scared and bloodless, and ran all the way to Su Hai's home. When you get to Su Hai's house, you don't have to say that Su Hai is really the brother-in-law of the red-faced man, whose real name is Wu Yifan, and opened a silver shop in the county town. That night, Wu Yifan and Gu Yan stayed at Su Hai's house.
When he went to bed that night, whenever Gu Yan thought of Wu Yifan's behavior on the road, he was always palpitating and could not sleep. At the third change of the night, Wu Yifan quietly got up, went to the West Wing where Gu Yan was sleeping, spit out his blood-red tongue, and immediately lit up the room. Immediately, he ate the servant who served Gu Yan, and at this time, Gu Yan, who was secretly sleeping, was so frightened that he almost fainted. Just when Wu Yifan was about to eat Gu Yan's thousand guns, Gu Yan shouted: "Old Master Guan saved me" (Gu Yan believed in Guan Yu). Gu Yan's voice actually appeared. The Guan Saint Emperor who had descended from the sky was actually here, with a red face and long hair, holding the Green Dragon Crescent Moon Sword, and slashed at the wu yi fan's brain gate. Wu Yifan didn't look good, and immediately turned into a giant butterfly and fought with Guan Yu, and after a while, the butterfly monster and Guan Gong suddenly disappeared.
Gu Yan lived so long that he encountered the "Immortal Fight". Suddenly passed out. Until the next day, when the sun went up to the three poles, Su Hai saw that Wu Yifan and Gu Yan did not come out. I couldn't help but be suspicious, kicked open the door, and found Gu Yan, who was paralyzed. Wait until Gu Yan slowly wakes up. He told him exactly what he had seen and heard last night. Gu Yan and Su Hai looked around, the house was full of blood, and it was unbearable to see, and Wu Yifan naturally disappeared. Unsettled, Su Hai immediately sent someone to the home of Jingwu Yifan to check the situation, only to see that Wu Yifan was discovered. Just at home, he was drinking and eating meat by the carbon stove, and he was confused about the interrogation of the people who came, and even apologized that he had forgotten that this day was his brother-in-law's birthday, and he had never been to Zhuxian Town.
The original title of this story, "Butterfly Monster", comes from the collection of novels "Zi Bu Shu" written by Yuan Ming in the Qianlong period of the Qing Dynasty.
