Chen Tianyu glanced at Xu Jie meaningfully, he didn't know if the captain of the criminal investigation team really didn't know about the concealment, or if he was unwilling to disclose the truth knowingly, because he and the other party didn't know each other very well, and the trust between them was really limited. Chen Tianyu also did not answer Xu Jie's question, before the case was clear, even for the local police and safety supervision department, he did not dare to reveal too much, so he found a topic to diverge, and at the same time called to inform Xu Jingnan to come as soon as possible.

Xu Jingnan was ordered to conduct autopsies on the bodies of the five deceased people in the Chuba gas explosion provided by the police, and he found that these people had multiple external injuries on their bodies, some large and some small, and after comparison, they should have been caused by the impact of broken stones. Burn marks were also found on the skin and hair, but they were not noticeable, and the burn was extremely low, presumably caused by flash burns, and neither the body nor clothes caught fire. As analyzed by the local forensic department, it should have been the impact of the blast wave, which caused them to be thrown far away, and eventually their heads ruptured and bleeding to death.

This conclusion is the same as the previous forensic test results, but the local autopsy was not performed at first, because the cause of death was very obvious, and it may not be considered necessary, but the cautious Xu Jingnan insisted on the autopsy, and attached the laboratory to test the food residue in the stomach and blood. The final report made Xu Jingnan find out a little, the deceased had no obvious signs of poisoning, there was no problem with the food in the stomach, and there was no other damage to the internal organs, but traces of the hallucinogen ether were found in the blood test.

He listed this unusual discovery separately and planned to re-examine it in the context of the case, because the discovery of hallucinogens alone does not explain anything, especially since the deceased did die of trauma and not suffocation, so the appearance of ether can only be regarded as a doubt.

At the same time, Chen Tianyu, who had a whim, took Kuang Suo and Liu Zichen to the No. 1 mine in the mining area in person. According to Li Yiting and Wan Yongkun, Wang Mazi did not let them enter the mine, which aroused Chen Tianyu's suspicion and strong interest. In these days of peripheral investigation, he also heard more or less about the legend of the butterfly elf, which spread very widely among the miners, probably saying that after seeing this terrible butterfly elf, some miners will die mysteriously.

Chen Tianyu and Kuang Suo wore hard hats and explosion-proof flashlights in their hands, and after making the necessary preparations, they walked into the long-abandoned No. 1 mine. Considering Liu Zichen's physical condition and the unknown danger inside, Chen Tianyu asked her not to go in for the time being, and stayed at the mine entrance to guard and respond.

After walking for a long time, they found that the humidity inside was aggravated and very dark, and everything except the place illuminated by the flashlight was plunged into darkness. They separated, one on the other, and carefully searched the ground, the top, and the walls of the mine to see what was special. Most of the area was uneventful, with moss scattered around, fine stones falling and covering the ground, and solid rock on the top of the mine.

Suddenly, Kuang Suo noticed something unusual, and hurriedly called Chen Tianyu over, and the two of them really found a terrifying-looking butterfly on the left side of the mine wall. The eyes of this butterfly are empty and godless, but it seems to be staring at itself, and the huge wings are open as a whole, and the small holes on it are dense, which makes people very uncomfortable to see, especially its appearance and body, which are uglier and bigger than ordinary butterflies, and can really only be described with grimaces. Chen Tianyu and Kuang Shuo were taken aback, and after a brief inspection, they quickly left in order to ensure safety, the creature was uneasy to see too much, but Kuang Shuo still relied on his super memory, and quickly wrote down its appearance and the internal structure of the No. 1 pit.

Seeing that the two of them came out so quickly, Liu Zichen greeted him and asked, "Tianyu, have you found anything?"

Chen Tianyu didn't want to describe it specifically to avoid scaring Liu Zichen, so he said, "We just saw the butterfly elf, and it is inside, and it really looks very special. ”

"It's so special, it's scary. Kuang Shuo didn't think about it so much, and said bluntly, "This is really the weirdest insect shape I've ever seen." ”

"Alright, Nine Paths. Chen Tianyu stopped him from continuing to describe, and analyzed alone: "I guess the reason why Wang Mazi wants to block Yiting may be because he has seen this thing before, so he seems to have changed recently, but he doesn't want others to be frightened and cursed in the same way." Of course, this is based on the premise that Wang Mazi has no other purpose. ”

Kuang Suo and Liu Zichen both nodded in agreement.

"In this way, with our true identity, we will directly interrogate Wang Mazi, since this guy is related to Tao Sansheng and Grimace Butterfly, it's time to officially interrogate him. Chen Tianyu ordered to go down and asked Kuangsuo to bring Wang Mazi to the bureau to see him.

--------------------------------------------------------------------

Li Yiting, Wan Yongkun and other team members all waited in front of the pit for a long time, but they didn't see Wang Mazi. On weekdays, he came very early and was never late, but today it had been more than half an hour, but he still hadn't come, and they immediately went to the chief dispatcher Zou Qi to report the situation. After working in the mining area for many years, Zou Qi had never heard of Wang Mazi being late for work, and he felt a little strange, so he called him, but no one answered, and then called home, and his wife actually said that Wang Mazi went out early.

Zou Qi felt that something was wrong with the situation, and Li Yiting was also faintly aware of the crisis, so they led this group of miners together and began a carpet search of the mining area and the vicinity, and they were busy for a long time, but there was still no trace of Wang Mazi. At this time, someone mentioned that Wang Mazi liked to go to the abandoned mine to smoke, Zou Qi was a little dissatisfied, but in view of the importance of finding someone, he personally brought someone over to check, and soon, in the abandoned No. 2 mine, they found Wang Mazi, who had been missing for a while. It's just a pity that when he found out, Wang Mazi had already lost his breath.

The miners were in an uproar, and it was really puzzling that a person who was fine yesterday died today, and died in this long-abandoned place. Li Yiting immediately made a covert investigation at the scene, and he found that Wang Mazi was smashed on the head by a large stone, and the blood stained the ground, and the stone seemed to have fallen loosely from the top. In the rest of the body, no wounds were found only from the naked eye, but because there were clothes to cover it, it was not completely certain for the time being, but what impressed Li Yiting was Wang Mazi's expression: his eyes were wide open, his mouth had not been closed, and he seemed to be greatly frightened. Li Yiting estimated that Wang Mazi was killed by a stone falling from the top of the mine, but this seems too unreasonable, right?

Xu Jie, the captain of the Criminal Investigation Brigade, and Chen Tianyu of the Beiting Detective Agency rushed over immediately after hearing the news, along with Xu Jingnan and several forensic doctors, and Liu Zichen was about to come to Wang Mazi, but when he heard the unexpected news, he also came to the scene to help Xu Jingnan investigate together. Worried about the exposure of his identity, Li Yiting retreated with Wan Yongkun after a brief survey before, mixed in with the miners who watched the excitement, the current situation is unclear, and there was a sudden incident of dead people, the truth is still far away, they naturally need to continue to lurk.

Mine No. 2, like Mine No. 1, was shut down on its own initiative after several accidents because safety could no longer be guaranteed. At this time, Wang Mazi was lying on the ground, his head was smashed open, in addition, there were indeed no other external injuries on his body, and there was no sign of fighting with people, through the investigation of the nearby ground, no other people's footprints and traces were found, but this place was not used for a long time, it was very dirty, and many places were covered with gravel and damp vegetation, even Wang Mazi's own footprints were not completely extracted.

Through the preliminary investigation of the scene, Xu Jingnan believes that the cause of Wang Mazi's death can basically be determined to be due to a heavy blow to the brain, which led to a head injury and death, and the murder weapon was smashed into a pile of stones not far from him. As for whether the stone fell automatically after a long time, or because of other reasons, it is difficult to judge as a forensic doctor, and it needs to be analyzed by professional geologists. Xu Jingnan took Wang Mazi's body back to the police station and decided to conduct an in-depth autopsy and examination, and he had a strange conjecture that needed to be verified, whether it would contain hallucinogens like those miners before him?

Chen Tianyu looked at everything in front of him silently, this seemingly accidental death was actually full of suspicions. Even if it happened to fall down, how could it be so coincidental at this point in time, it happened to be smashed down by Wang Mazi when he happened to pass by, and hit his head impartially. Moreover, he was just about to interrogate Wang Mazi, and he got the news of his death, judging from past experience, the probability of such a coincidence occurring is extremely low, and the probability of premeditated crime is very high.

As for the other melon-eating masses, there are many discussions: Wang Mazi saw the grimace butterfly, and soon he really died, could it really be the curse of the butterfly elf?

Chen Tianyu naturally didn't believe it, Wang Mazi's time and place of death were quite special, he faintly felt a chill, since the arrival of Beiting, there was an invisible black hand in the entire mining area that was secretly controlled, and their investigation on the surface was within the control of the other party, and this intuition of being inexplicably monitored made him very uncomfortable.

At the beginning, the original intention of the Beiting Detective Agency was only to receive a whistleblower on the website of the Micro Alliance to reveal that the mining area had concealed the death toll of the gas explosion, but as the investigation gradually deepened, they did not get any effective evidence when they knew that the report was basically the truth. And everyone here feels like they're in the middle of the game. Although the local authorities were very cooperative and allowed Beiting to intervene in the investigation in an all-round way, now there is a strange legend of the ghostly butterfly, and then the important witness who has just been found has died in front of his eyes.

Chen Tianyu, who had just encountered the grimace butterfly, frowned, he needed to think carefully and find the entry point of the case as soon as possible.

At least, the Grimace Butterfly he had seen was not as evil as the legend, and it didn't take the initiative to attack him.

What's going on here?
