Three poles on the sun, abandoned small building.

The dragonfly crouched on the ground and looked at the footprints of the single feet of various sizes.

"Sister, you've seen three incense sticks, and you're going to see through the floor." Feng Fu held his face in both hands and squatted to the side to look at the dragonfly.

"Do you wonder how a normal person's footprint can be only one?" The dragonfly said, pointing to the footprints on the ground.

"You've asked me this thirteenth time, strange, strange." Feng Su said perfunctorily.

"Say, how did these footprints go?"

"You've asked this question more than ten times, I don't know." Feng Su sighed, stood up and found a place to sit down.

"How could there be such strange footprints......" Dragonfly looked at it over and over again with interest. It's the first time she's grown up to encounter such a case. It's so much fun.

"Sister......" Feng Xu touched her flat belly and called her complainingly.

"What's wrong?" Dragonfly asked without replying.

"I'm hungry, let's go get something to eat first."

"Eat?" Being reminded by her like this, Dragonfly did feel a little hungry, but she couldn't solve this puzzle, and she was unwilling to leave like this.

"You go eat it yourself, and bring me a random cake."

Feng Xu looked at her with a sad look again, but the dragonfly didn't pay attention to her mind at all, so she had to leave by herself.

Not long after, Dragonfly heard thin footsteps behind her, and she asked, "You're back so soon?" ”

After asking, the footsteps stopped abruptly, and the dragonfly quickly turned around, only to see that there was nothing behind it, but there was a faint smell in the air.

"Suffered?!" The dragonfly hurriedly ran to the window and looked down, but there was nothing. She hurriedly rushed downstairs to look for it, but still found nothing.

"No......" Dragonfly appeared at the door on the first floor. She clearly felt someone approaching her just now, and in such a short period of time, if the person didn't go out, then she would still be in this building.

"What shouldn't you?" The figure of the phoenix appeared at the door.

She was still carrying a scallion pancake in her hand, and although she was tied to a brown paper bag with hemp rope, the dragonfly still smelled the fragrance.

"Did you see anyone when you came back?"

"This place is so remote that there is not even a ghost, let alone a person. If it weren't for my good work, I guess I would have just arrived at the market by now. ”

"The market is open today?"

"It's open every day, but some time ago, the things in the county government were rumored to be messy, and everyone didn't dare to go out to do business."

Dragonfly nodded knowingly. Changhe County is nearly twice as large as Qinghe County, and there are more people, so there is no need to open the market on even days like Qinghe Town.

"Guess what I just asked?" Feng Fu looked at the dragonfly with a smile.

"What did the lady hear?" The dragonfly asked.

"This haunted house really has ghosts."

"Wow! It's so scary! The dragonfly made a frightened face.

"On the first day of every month, in the first few days of the month, there will be all kinds of sounds in this building, and some people will see a lot of people walking back and forth inside."

"Oh~ It seems that a group of unjust ghosts are complaining to Lord Yama." The dragonfly shook its head and said.

"Sister, do you think those footprints are the ones they left behind?"

"Well......" the dragonfly rubbed its chin for a few moments, and said mysteriously, "very likely." So what we have to deal with is not people, but a group of ghosts. ”

Feng Xu asked Dragonfly with a serious expression: "Sister, do you want to ...... I'm going to catch a Taoist priest to catch a ghost? ”

"Go, it's best to tie up all the Taoist priests in the city, if you don't worry, the monks will also be arrested, make up the whole."

Feng Xu was just about to persuade the dragonfly not to make such a big fuss, when she saw that the corners of the dragonfly's eyes were a little crystalline, and the corners of her mouth couldn't stop twitching. She instantly realized that it was the dragonfly who deliberately teased her, and her face turned red with anger for a while.

"Sister! You're kidding me! ”

"With you, how can you judge me with such hurtful words?" Dragonfly said seriously.

"And said they weren't kidding me!" Feng Fu stomped her feet angrily, rushed up and pinched the itchy flesh of the dragonfly, and the two rolled on the ground and made a fuss.

While there was a lot of noise, the dragonfly suddenly saw a clean oil lamp in the corner.

"Stop! Look what's there. The dragonfly pointed to the lamp and said.

"Isn't it just a lamp, you still want to trick me!" The phoenix flopped over and rode on the dragonfly and scratched her again.

"Hahaha...... You damn girl...... The oil lamp did not fall into dust...... Hahaha...... "The dragonfly huddled in a ball to avoid her attack.

"That's like ...... What? Feng Fu turned over and looked at it, and there was really no dust.

She hurried over and took out the oil lamp. The handle of the oil lamp had been faded and shiny, and the small bowl of oil was black, and it was impossible to see what it was. At first glance, it looks like an old object that has been used for many years.

"Someone brought it?" Feng Xu asked.

"No, someone uses it a lot, and I guess I wiped it not long ago." Dragonfly replied.

"Yesterday! Yesterday I saw the lights on inside! Feng Xu said. But then she wondered, "But when I came in, I didn't see anyone, and I didn't see anyone go out." ”

"In this building, there may be a secret passage." Dragonfly guesses.

"And what about the haunting on the first day of the month?" Feng Xu still didn't understand.

"On the fifteenth day of every month, the door of hell is wide open, and when the yin energy is at its highest, it should be the time when you want to make noise. First...... Unless the first day of junior high school can gather all the people. Just like our market in Qinghe County, there are only a few days a month when farmers can come up to catch the market, so the big market will be opened. ”

"Yes...... What kind of people are only available on the first day of junior high school? Feng Xu asked.

The dragonfly's gaze suddenly turned to the county office.

"Every month, county officials, big and small, need to go to the county government to participate in routine official arrangements. The time set for each county is different, Qinghe County is set in the middle of the month, and maybe Changhe County is set on the first day of the month. And that person is only convenient to appear here when official arrangements are made. ”

Several positions suddenly came to the dragonfly's mind.

Feng Xu followed her train of thought for a while, pointed to Xiaolou and said, "Then why are there only footprints on the third floor, or a single footprint?" ”

Dragonfly can't answer this question, and she has the same doubts about comparison.

"Maybe there is some secret passage in this building, and when we find the secret passage, we will naturally know what is going on."

"Or ...... Getting around the neighborhood? Feng Xu asked.

"Let's go, anyway, I don't have the heart to investigate the case now."

So, the two walked hand in hand in the direction of the market. In the abandoned small building behind them, a pair of eyes suddenly appeared, staring at the distant backs of the two.

——

After eating, Yun Feng arranged the basic matters, and took the prison key to interrogate the people he caught last night. Now it is almost certain that Ning Yong, who is far away in Chongzhou, is really a fake, and all the catchers in the county government have either been killed, or escaped from the city and hid in the mountains.

There is also the valley not far from Changhe County, the bodies at the bottom of the valley, most of the deceased have been identified, and most of them are the dead Catcher and his family. Others were merchants passing by.

Two of the bodies were so badly mutilated that they could not be identified, and six of the bodies were confirmed to be members of Ning Yongzhen's family.

After finding out these clearly, the next thing is the motive, why did they kill Ning Yongzhen to replace his identity, why did they replace all the catchers in the county office, and what was their purpose.

Except for a few counties in Chongzhou that have suffered such incidents, have the same things happened in other places?

Intuition told him that this time the emperor summoned him back, appointed him to the post of Shaoqing of Dali Temple, and promised that he could help General Shi overturn the case, and there should be an ulterior conspiracy behind him waiting for him to solve.

"Master Yun, I just had dinner, where are you going?" Xu Yi happened to come to the county office and collided with him.

"I'm going to the prison to see those prisoners, what is the matter with Lord Xu?" Yun Feng asked.

Xu Yi showed a serious expression, mysteriously took out an open letter from his sleeve pocket, and quietly handed it to Yun Feng.

"This is something that adults asked me to investigate, and when I encounter some tricky things, I need to be cut by adults."

Yun Feng took the letter, gave Xu Yi a reassuring look, and motioned for him to go back first. When Xu Yi left, he changed his steps when he wanted to go to the prison for interrogation and went to a temporary residence.

In the evening, a catcher stumbled to knock on Yun Feng's door, waking him up from his sleep.

"Lord Yun, Lord Yun, it's not good!"

"What's the alarm?" Yun Feng asked.

"Prisoner...... Prisoner ......"

Yun Feng got up suddenly, ran over a few steps to open the door, and asked him, "Run?" ”

"Nope! No! Dead, all dead! ”

"What?!" Yun Bong raised his voice.

If the person runs away, he can find a way to catch it again, anyway, he has already ordered the painter to paint the portrait of those people, and if he dies, he can't ask anything.

"Go! Get the job for an autopsy! After saying that, Yun Feng ran to the prison in a hurry. He blamed himself for being snoozy all the way, and he should have gone to prison for interrogation immediately after reading the letter.

When he ran to the prison, he saw Feng Xu standing at the door, and Feng Xu waved at him happily.

"Master Yun, that's a coincidence!"

"Why are you here?" Yun Feng asked.

Feng Xu said humbly: "We...... I found something and wanted to report it to the adults, but it was a coincidence...... I heard someone shouting here, so I came over......"

As soon as Yun Feng saw her like that, he knew that most of the two of them ran out to go shopping halfway through the investigation of the case. sighed secretly, but he didn't mean to blame them, he only felt helpless and tired.

"Do you want to go in with me?" Yun Feng asked.

"My sister asked me to guard here, saying that no one can enter except Lord Yun." Feng Xu replied.

Hearing such an arrangement, Yun Feng's heart was much clearer, it seemed that the dragonfly had discovered something, and he was worried that there would be many people and confusion.

"So you will have to keep it." After speaking, Yun Feng lifted the hem of his clothes and walked in.

Feng Xu watched his snow-white back gradually shrink, even in the shadows, it would not be dim.
