After inspecting Yao's house, Xiao Rui and the four of them left here, and on the way to Chengxi Study, he shared his discovery with Guo Jia.

Guo Jiaxian said: "Basically, it can be judged that Master Yao was killed by him, and it was killed by an acquaintance, because the deceased was sitting on a chair and did not resist, and according to the traces of blood spraying after the beheading, the murderer moved his hand from behind the deceased, and it should be the murderer's sudden hand when the two were talking." As for why he had to cut off his head, in my opinion, one is the murderer's serial plan, which deliberately caused panic. The second is to cover up the traces of an acquaintance's action, after all, if an acquaintance does it from behind, the deceased's face after death has a calm expression. ”

"Then how did the other party complete the murder in the closed room? The doors and windows were bolted from the inside. Xiao Rui asked.

Guo Jia explained: "I just carefully checked the wooden bolt of the bolt door, and the wooden bolt is broken in the front, indicating that the wooden bolt is only stuck at the front end of the card slot, and there are burnt marks at the end of the wooden bolt, so I guess that the killer placed an item similar to gunpowder at the end of the wooden bolt, ignited it to produce a certain impact force, and pushed the wooden bolt into the card slot, but the thrust was lighter, and all of them only advanced the front part." In addition, I found black ash on the ground, which was just right to test my suspicions. ”

"Oh?" Xiao Rui was slightly shocked, gunpowder was his magic weapon, how could it appear in Songyang County, but soon, Xiao Rui understood. As an alchemist, Ge Hong can discover the existence of gunpowder from the method of subduing fire, and other alchemists will naturally find out as well.

It's just that the current method of ambushing fire is still in the early stage and has not been taken seriously, so gunpowder has not been completely born on the mainland.

In other words, some people have inadvertently formulated the earliest gunpowder, which is not very powerful, but still uses a certain impact force after ignition.

Just like in the previous life, the method of ambushing fire was invented in the Tang Dynasty, and there was a prototype of gunpowder, but it was not until the Song Dynasty that it was used in military affairs, and there were larger attacks, and the early gunpowder was only used for acrobatics and performances.

Guo Jia said again: "What did Your Highness discover?" ”

Xiao Rui said: "This Master Yao's family has a lot of money, but his son doesn't know what business he does, according to the deceased's son, he once asked and was reprimanded, which shows that Master Yao's business has a big problem, and settling in Songyang County is more like hiding from the enemy." Secondly, I asked the deceased's son if he had any friends during his lifetime, especially outside Songyang County, but the deceased's son said no, and never heard the deceased mention it. However, on the fourth day of April every year, the deceased has to leave Songyang County, and he doesn't know where to go! ”

"The deceased used to be a big businessman, and he didn't have any friends outside, and at this time on the fourth day of the fourth month of April, how did it make me feel so familiar, as if it was a day, I can't remember it for a while."

Guo Jia nodded and said: "The first deceased revealed too many problems, let's check the other two deceased, these three people must have a connection, as long as they can find the connection between them, they can find out and reveal the truth." ”

"That's right!" Xiao Rui felt that this trip to Songyang County became more and more exciting.

When I came to the Ming Academy, the school that was supposed to read aloud was empty, and it was extremely depressed, and there was a murder in the school, and the students were afraid to study, so they went home one after another, leaving Songyang County.

Wu Biao, the county order, was not stupid and did not let the five witnesses leave, so after the four of them came, they could continue to ask.

Guo Jia asked the five students about the situation that night, while Li Yuanfang and Dian Wei checked the external environment, especially the trajectory and route of the headless corpse flying away, and carefully checked the environment near the trajectory.

And Xiao Rui came to the room where the headless corpse tore up Song Fuzi.

It is a simple study with a simple décor, a set of tables and chairs, a desk, and several bookcases, which are filled with books.

Xiao Rui flipped through the books that Song Fuzi read, and then looked at the drafts of his calligraphy, and when he opened a few paintings that he had not yet completed, he suddenly found that the content of one of the paintings was very familiar, and if you looked closely, isn't this the Pudu Temple next to Danyang Lake? Continuing to look through, Xiao Rui found that the content of a painting turned out to be the scenery of Kyoto.

The information shows that this Song master was born as a child and did not even pass the township examination, so he opened a school in a county like Songyang County to teach students. But judging from his paintings, the experience of this Song master is not simple, at least he has been to Kyoto.

Next, Xiao Rui didn't find any other useful clues.

Guo Jia asked five students, they were all eleven or twelve years old, that night was dark and windy, and their vision was not too high, they were about to ask Song Fuzi for questions, but suddenly saw a bloody headless corpse running out, holding two arms in his arms, and then soared into the sky and flew away.

But when Guo Jia asked about the height and general figure of the Feitian corpse, the five of them all shook their heads, they were all stupid at that time, where did they care about carefully distinguishing?

Secondly, Guo Jia was also curious, why didn't the five students go home so late and stay in the school so late? According to the five people's answers, it was Master Song who specially asked them to stay, saying that they had important knowledge. Behold... This is what happens when knowledge is not imparted.

And Li Yuanfang and Dian Wei, according to the trajectory of the flying corpse flying away described by the five students, carefully checked the trees around the trajectory.

This school was built in the middle of the mountains and forests, and all the rooms were lined with trees, so it was not impossible for the murderer to tie ropes to the trees and create the illusion of flying with the help of external forces.

However, the two men checked the surrounding trees, and both found traces of rope binding and friction.

Just when the two thought that there was no clue, Li Yuanfang in front of them suddenly found that there was a dense bamboo forest ten zhang away in front of the school.

Li Yuanfang suddenly thought of a possibility, and immediately went to the bamboo forest to check, and after careful observation, he finally found traces.

After the four of them finished inspecting the school, they began to get together to discuss and discover.

Xiao Ruixian said: "This Master Song is by no means an ordinary old pedant, just like the first deceased Master Yao, it is definitely not as simple as it seems. But there are fewer other clues, and you can't find deeper content. Bonghyo, where are you? ”

Guo Jiadao: "Basically, it can be concluded that it was not a headless corpse murder at all, but a conspiracy designed in advance, a play performed by the murderer, and the murderer also knew the second deceased, and the murderer deliberately let the deceased leave five students to serve as eyewitnesses, so as to confirm the evidence of the headless corpse killing." On the day of the crime, it was dark, and the five students were young, so in the face of the so-called headless corpse, how could they bother to observe, and only remember that it was a headless corpse, which was equivalent to making false testimony for the real murderer. ”

At this time, Li Yuanfang also told the clues he found: "I checked the trees on both sides according to the trajectory of the headless corpse flying away, and there were indeed no traces. So, how did the headless corpse fly away? Later, I found out that there was a bamboo forest in front of the school, and I found traces from the bamboo forest. It turned out that the murderer used the strong tenacity of the bamboo to first bend a few bamboos with a rope, and then tied them to the corpse with a rope dyed black. ”

Xiao Rui and Guo Jia glanced at each other, Xiao Rui smiled: "Let's not talk about why the murderer killed three people, what is his purpose in doing this?" Just to create a horrific killing effect? ”

"It's not that simple, I feel that the murderer's purpose in creating ghosts to kill people is to cause panic and let some people in Songyang County leave Songyang County, so convenient for him to plan something!" Guo Jia calculated.

Xiao Rui nodded and said, "It is very likely that the people of Songyang County are already panicking now, and everyone who can go is gone." In that case, let's go to the third deceased and maybe find something new! ”

In this way, the four of them immediately moved to the south of the city and came to the pharmacy of the third deceased.

This pharmacy is very ordinary, it is an ordinary pharmacy, a long counter, behind it is a Chinese medicine cabinet, this pharmacy is also responsible for helping people boil medicine, there is nothing peculiar.

Guo Jia questioned the deceased's wife, Sun, and she was heartbroken and painted the scene.

It was a noon, his husband was drying medicinal herbs in the backyard, he went for a long time, he didn't come back for a long time, and the pharmacy was busy, so Sun went to the backyard to call the deceased, not thinking about it, just came to the backyard, he saw his husband being held by a headless corpse, unable to move, and then immediately after, the fire suddenly burst out from the feet of the two, and black smoke, accompanied by a crackling sound, the two of them were on fire, Sun listened to the screams of his husband, frightened, and hurriedly went to call someone, but in the end it was too late.

After listening to Sun's description, Guo Jia asked, "Sun, can you smell the pungent smell of sulfur when the fire and black smoke come out from the feet of Sun's shopkeeper and the headless corpse?" ”

Sun recalled, nodded immediately, and said, "Indeed." ”

Xiao Rui asked: "You just said that your husband was held by a headless corpse and couldn't move, and even after his body caught fire, he could only scream and couldn't move?" ”

"Yes, yes, the headless corpse was strangled too tightly." Sun wiped his eyes and cried.

Xiao Rui and Guo Jia glanced at each other, it seemed that the deceased had been drugged, so he couldn't move, how could it be that the headless corpse was strangled too tightly. In addition, the flames under the feet of the two must have been caused by the ignition of gunpowder, and it is believed that there are also flammable things on the two of them, which is why they burn so quickly.

As for this play, it is naturally also to let the Sun family see with his own eyes and see the illusion of a headless corpse killing, so as to cause greater panic.

However, I know how the murderer killed, but I still have no clue who the murderer is and what his intentions are.

"Oh yes, what does your husband do on the fourth day of April every year? Do you have any impressions of this day? Xiao Rui always felt that this day was very familiar, but he couldn't think of what it was.

And when I was in the Ming Scholar School just now, the five students also recalled that it seemed that the tragic death of Master Song would be suspended from class every year around this period of time, and he didn't know where to go!

Hearing Xiao Rui's inquiry, Sun didn't hesitate, but nodded!
