When later historians of the Central Continent recorded this period of history, they always talked about the joint performances of Zhao Xifeng, Gu Qingyuan and Dong Erpang who changed the general trend of the world several times, but in fact, the first cooperation between the three of them started from this small town on the edge of the empire tonight.

Zhao Dong and Gu took advantage of the night to touch the laundry in the south of the town, all three of them had already taken pictures, their footsteps were silent, and there were no pedestrians on the street, and they were not noticed by others all the way.

After coming to the laundry in the south of the city, the three of them climbed over the wall and entered.

On the day of the crime, eight people disappeared at the same time, so the laundry had been carefully investigated several times before by Mu Tie and the crowd, but there was no result, and for the three children who only had a list of clues, they didn't have much choice, so they had to start from here.

After entering the courtyard, the three of them found that they had locked the door after the last time they collected evidence, Dong Erpang was about to smash the lock hard, Zhao Xifeng took out an iron needle from his book bag, stepped forward and twisted it, and with a "click", the lock was opened.

Dong Gu and the others were dumbfounded.

Zhao Xifeng pushed the door in, and then turned around and said, "I studied this when I was six years old when I went to steal wine from Aunt Li's wine cellar, and the lock in the town has not been able to stop me." ”

The two followed Zhao Xifeng into the room, but the scene in the room was something that the three of them never expected, tables, chairs, counters, utensils, the normal furnishings needed in any room were not here, the room was surrounded by walls, not to mention any clues, even the floor was cleaned spotlessly!

The three of them stood in the empty room, looking at each other and smiling bitterly.

After a while, Dong Erfat stomped his feet, cursed a swearing, and then followed the method he learned from his uncle and uncle, and tapped every piece of the head in the room with his fingers, looking for possible dark rooms, but found nothing.

"I said that it must be a trip for nothing," Dong Erpang shook his head and sighed, sitting on the ground, "What even Uncle Mu can't find out, how can a few of us little kids who have never handled a case help anything, according to me, we still have to start with Chen Mo and his family, maybe they will know Chen Mo's whereabouts, I don't believe it, the surnamed Chen looks like a ghost who is afraid of his wife and is afraid of death, and he really wants to escape without talking to his mother-in-law!"

Gu Qingyuan shook his head and said: "No, this matter can't be known to others, only a few of us can act in private, how do you know that those killers have completely withdrawn from the town? ”

Zhao Xifeng nodded and agreed.

"Besides, it's not for nothing. Gu Qingyuan shrugged his nose and said with a smile, "Have you ever thought about why this family has to take time out to clean the ground before they hurriedly evacuate? The ground must be cleaned to clean the ashes after the incineration, believe it or not. ”

Gu Qingyuan stretched out his hand and pointed upward, Zhao Dong and the others stole it to look, only to see that there was a large scorched mark on the ceiling in the center of the house, which seemed to be blackened by someone in the room.

"So what? Everything that should be burned has already been burned. Dong Erpang frowned and asked.

"It was nothing, but it shouldn't have been, and they burned something that shouldn't have been burned. Gu Qingyuan smiled confidently and asked, "Since you entered the room, have you smelled anything different?"

Zhao Xifeng sniffed around, and said in a deep voice, "Sandalwood?"

"It's sandalwood, but it's not ordinary sandalwood" Gu Qingyuan nodded and said: "It's the purple river sandalwood in Laolongtan, Gushan County, this kind of incense calms the nerves, and the smell lasts for a long time after burning the incense. My family has always been engaged in north-south trade, and I haven't seen each other a few times in so many years. ”

"So you mean, if you find this incense, you will find the owner here?" Zhao Xifeng asked with a frown.

Gu Qingyuan smiled and said: "Yes, so if you smell this kind of fragrance in the town again, then it must be the person we are looking for, you have to remember this smell today." ”

Dong Erpang said disapprerovingly: "Since the person has already run away, I have to say two things if I can't come back." What's the use of just remembering the smell? You can't walk like a dog every day. ”

Gu Zhao and the others ignored him, nodded to each other, and walked out.

"Hey, where are you going next?"

"Li Sijia!"

After the three of them joked, they walked to Li Si's house in the west of the town, although the town was not big, but it was not close to the west of the town from the south of the town, and when the three finally arrived, it was already ten midnight.

It's still a familiar routine, Zhao Xifeng pries the door lock, and sure enough, the room is like a laundry in the south of the city, with four walls in vain, nothing is left, Dong Erfat sighed, and said in a mournful voice: "Alas, I wanted to do a big thing, but in the end, after working all night, I smelled a fart." ”

The two still ignored him, and carefully inspected the room, Zhao Xifeng frowned and said: "No, this place is different from the laundry, where the traces were buried by fire, but this place was just emptied. ”

"What's the difference? Maybe it's just that Li Si is lazy, just look at the way he is lazy and basking in the sun on weekdays, you can know that he is a lazy person. Dong Erpang shook his head and said, he had nothing to gain from working all night, which had made this little fat man feel anxious.

Gu Qingyuan shook his head: "Each organization has very strict rules on how to eliminate the traces of its own stay and existence, it is impossible to deal with it so casually, someone must have helped him dispose of the traces here, and after martial law that night, no one can leave the town without registration, so the person who handles the traces must still be there! That is to say, we only need to find this person!

The three of them, looking at each other, were all a little excited, this was the biggest discovery of the three tonight.

"And we can be sure of one thing. Gu Qingyuan said, "Li Si really has something to do with the people in the laundry. ”

"How can you see it?" Dong Erpang asked.

"Because there is also the smell of purple river sandalwood here. Gu Qingyuan replied as he should.

"Are you a dog?" Dong Erpang finally couldn't help it, "Smell it again?" I can still smell a little bit in the laundry just now, and there's obviously nothing here!"

"Mr. Zhou once taught us the technique of clearing the nose in class, which is specially used for cultivators in the two realms of first sense and body to capture subtle smells in the air, don't you?" Gu Qingyuan asked in surprise.

Dong Erpang and Zhao Xifeng glanced at each other. At the same time, he smiled awkwardly: "Of course it will, how could it not?" and then shrugged his nose fakely, and then nodded thoughtfully, indicating that he really smelled it, Gu Qingyuan smiled lightly, and did not debunk it.

Zhao Xifeng carefully sniffed every corner of the room and said: "Sandalwood or something, of course you can't hide it from me, but have you smelled a stronger smell, a..."

Zhao Xifeng pondered for a long time, pondered the wording, and said, "Greasy smell of blood?"

"Nonsense, don't you look at who Li Si is cooking for?" Dong Erpang said angrily.

Zhao Xifeng shook his head and said: "No, since we entered the house, there has been a faint fishy smell, and now after opening the door for ventilation for so long, this smell has not only not dissipated, but has become stronger, and the source of the smell is not in the house, but in..."

The three of them turned their eyes to the door together, and saw a chubby figure as a mountain blocking there for some reason, holding a kitchen knife with no color in his hand, and was sighing in a low voice, his voice was greasy and hoarse, with a trace of indescribable vicissitudes and obscenity.
