After all this, it was already dawn, Uncle Li covered up everything in the house, took Yang Yi and Wei Ergou out casually, and then called the peach wood demon to go to breakfast together.

After eating, Zhu Xiyan was busy with his own military affairs, and Uncle Li did not keep him, so he secretly sent Yang Yi and Wei Ergou out to look for the copper rooster.

Out of the yamen, Yang Yi and Wei Ergou wandered around the street for a long time, the hell in this stone horse shop city is not big, there are a few antique shops have gone, this army is in chaos, whether it is a rich family or ordinary people, there is silver on the body to keep the use of disaster prevention and escape, so those few antique shops are full of doors, and the empty shelves inside are also full of dust, a few old people who look at the shop looked at Yang Yi and Wei Ergou who came in drowsily, and they didn't know.

Disappointed, Yang Yi and Wei Ergou came out of the last antique shop and stood on the street blankly, not knowing where else to look for the copper rooster. Suddenly, Yang Yi and Wei Ergou saw the crowd in front of a private house in front of them, shouting as if something had happened, and involuntarily walked over there.

After getting closer, they found that it was the old man they had rescued before, who was holding the body of his granddaughter in the courtyard crying and grabbing the ground, which made people unbearable, and also accompanied the old man to cry.

As soon as they saw that they knew the old man, Yang Yi and Wei Ergou couldn't help but walk up to the old man, first looked at the girl's corpse, and found that the girl's face was bruised, her lips were blue, and her slender neck was full of red scars, which looked like she had been strangled to death.

"Uncle, didn't you go to your relatives, why haven't you left yet? What's going on here? Yang Yi, out of professional sensitivity, looked at the scars on the surface of the girl's corpse, and basically concluded that the girl died of mechanical suffocation caused by being choked by someone's neck, so he squatted down, looked at the old man and asked.

When the old man saw someone asking, he raised his teary eyes, and saw that it was the two fathers who had come to his rescue yesterday, and he was lying on the ground, crying loudly.

After crying for a while, the old man stopped his grief and told Yang Yi and Wei Ergou about the changes that had happened at home. It turned out that after returning home last night, he and his granddaughter packed up the few clothes at home, and because the Taiping Army imposed a curfew at night, they could not leave the city, so they wanted to rest for one night and go out of the city tomorrow to join relatives and friends.

It was night, the old man who could not leave his homeland could not sleep, he sat in the hall with a lonely lamp, in the middle of the night, when the old man was confused and would not sleep, he heard the sound of babbling in his granddaughter's room, at first, the old man thought that his granddaughter was tired, talking in his dream, but after a while, he saw that his granddaughter's babbling did not stop, but made a heavier and heavier wheezing sound, and he knew that it was wrong. Only then did he panic and shouted for help, and the surrounding neighbors rushed over when they heard the sound, and someone went to invite Lang Zhong, but when Lang Zhong arrived, a fresh life was already scattered and dusty, turning into a soul in the cold wind and passing away.

After listening to the old man's story, Yang Yi and Wei Ergou carefully examined the scars on the girl's neck, and found that those pinching marks similar to those left by fingers were very small, definitely not like the palms of adults, but more like the palms of children or dwarfs, and each pinch mark was stained with black peat, which was incredible.

Yang Yi and Wei Ergou left the old man and went into the room where the girl lived before her death to take a look at the scene, only to see that there was a vermilion wooden bed near the southeast wall of the room, decorated with a cloth curtain, and a thin quilt was stacked messily on the bed.

Looking around, the whole room had no windows, only a wooden door leading to the hall, and outsiders would never be able to enter the girl's boudoir without passing through the hall.

After looking at the building structure of the scene, Yang Yi felt that the only thing that killed the girl was that the murderer sneaked into the house through the main door, and then entered the girl's boudoir through the hall, committing the crime of murder.

However, the old man sat in the hall all night, even if the murderer entered the girl's boudoir while the old man was asleep (there is another difficulty, that is, the main door is in the hall, how did the murderer judge that the old man was in a daze, so that he could grasp the time of sneaking into the room so accurately?). According to the old man's description, after he heard his granddaughter's moaning for the second time, he went in to check and found that his granddaughter had collapsed on the bed, indicating that the murderer had finished the crime and fled. But according to the old man's recollection, his granddaughter made a sound twice, and the time between the voices was very short, and he was worried about his granddaughter. He didn't sleep all the time, so how did the killer slip out from under his nose, or did he hide somewhere at the scene and then slip away when a neighbor came to help?

Thinking of this, Yang Yi looked at the scene again and found that in that cramped room, except for a low wooden bed that could not hide people at all, there was a vermilion lacquered dresser, and there was no place for people to hide, but how did the murderer disappear mysteriously in front of everyone's eyes?

"Will there be a tunnel here?" Listening to the questions in Yang Yi's heart that he said, Wei Ergou reminded thoughtfully.

"yes, that's really oversight." Yang Yi patted his head and remembered the tunnel that Lu Jingtian set up under the master bedroom leading to the ancient tomb, and couldn't help but shout.

Subsequently, Yang Yi and Wei Ergou were banging on the floor of that room, but after tamping the loess, the ground that was only laid with green bricks was as hard as iron, and there was no tunnel or secret passage entrance at all.

"This is really evil, hey, this murderer is not a human, but a ghost who can change, hehe" Wei Ergou looked at Yang Yi, who was also unclear, and quipped.

"Ghosts, ghosts, ......" Wei Ergou's joke woke Yang Yi up, and after muttering a few words of ghosts, he reached out and touched the ground, and the green bricks were very damp, as if they had just been sprinkled with water.

Yang Yi's heart moved, and he went under the girl's bed and touched it with his hand, and the blue brick floor under the bed and the side of the wooden bed base facing the ground were also full of water droplets.

"There are nine droughts in Shanxi in ten years, and the summer is as expensive as oil, and now it is a dry and cold winter, where does so much water vapor come from?" Yang Yi looked at Wei Ergou, and suddenly felt that the tone of his voice and the way he thought now were becoming more and more like a Taoist priest chattering with gods.

"Water vapor? What do you want to say, do you really think this is a case of murder in a closed room using an ice distiller as a murder weapon, you Conan has seen too much, no, your dynasty doesn't have Conan, no, what's wrong with you, Lightning, look at the two of you, it's so crazy, don't make trouble, it's good......" Wei Ergou saw that Yang Yi's expression was wrong, and asked with some concern.
