As an important witness and the victim's family, Wang Ruyun's account has confirmed what happened to Wang Mazi before his death from the front, as Chen Tianyu speculated, Wang Mazi inadvertently saw the grimace butterfly in the No. 1 mine, which was associated with the rumors in the mine for many years, so he was frightened and lost his soul, and hurriedly arranged the aftermath, no wonder that in the next week, Li Yiting and Wan Yongkun, who worked under Wang Mazi, felt that the team leader was absent-minded, and now everything has been accurately explained.

If before this, Chen Tianyu still felt that this legend was only limited to words, then the existence of Wang Mazi's mysterious death soon after seeing the butterfly will indeed make people think about it. Could it be that there is really a curse of the butterfly elf? Isn't it true that anyone who has seen a grimace butterfly will meet with an accident?

Chen Tianyu felt that this was still completely unacceptable, if this was the case, he had also seen the grimace butterfly with his own eyes, but he was not alive and well? Moreover, Cao Hongwei's son and Cao Bao were killed in the field, he had never gone down the mine, nor had he mentioned seeing the grimace butterfly, but he still died, and Yan Baoping did not say that her husband and son had mentioned seeing butterflies.

It's just that what happened to Wang Mazi doesn't seem to be groundless, Chen Tianyu suspects that someone may have used the butterfly elf to design and murder Wang Mazi. If this is the case, this person must know the situation in the mining area very well, and he must know the story of butterflies very well, so that he can use it so properly.

Chen Tianyu still has a doubt, if Wang Mazi hadn't gone to the mine to hang out, he should not be able to see the butterfly elf in the abandoned mine, so would he die later? Or would he kill him according to the murderer's plan whether he saw it or not?

There seems to be no evidence of a breakthrough in these doubts for the time being, but according to Shen Mingyue's discovery in the valley and Wang Ruyun's explanation, both lines point to the same clue again, that is, the butterfly elf. The investigation of the real body of the ghost-faced butterfly has also become the main direction of the coal mine explosion case, and Xu Jingnan, under the arrangement of Mei Yuanzheng, entered the mine layer where the explosion occurred in the No. 3 mine, hoping to find traces of the butterfly. But what disappointed him was that after searching in the level for most of the day, he didn't find any clues about butterflies, and there were no butterflies at all in that place!

But he didn't give up, or in the cracks of the rocks, he found some tiny insects, which seemed to be larvae, and could only crawl, not fly, Xu Jingnan caught some into the evidence bag, and planned to go back and test it. Later, Xu Jingnan proposed that he wanted to go to the blocked No. 2 mine to check, and Mei Yuanzheng was a little embarrassed, after all, the order to seal the well was just given by himself. However, at Xu Jingnan's strong request, in order to cooperate with the investigation, Mei Yuanzheng still found professional excavators, and spent several hours of hard work to reopen a small hole in the No. 2 mine that had been filled in the pit mouth for Xu Jingnan to visit.

This is the place where Wang Mazi was found dead, after his accident, the police have sealed off here, except for the people who investigated the case, there will be no more idle people in the future, until the mine decided to block the mouth of the pit. Although it has been a while since Wang Mazi's death, it is still a relatively well-preserved crime scene that has not been damaged too much.

Xu Jingnan walked in alone and lingered for a while at the location of Wang Mazi's body found, this area had been inspected in detail before, and there was no other harvest except for the incomplete footprints found. As for the big stone that caused Wang Mazi's death, the results of being brought back for testing were automatically detached, and no human fingerprints were found on it. However, this cannot be completely ruled out as murder, because after all, there is a possibility that the murderer wore gloves and picked up the fallen stones to kill Wang Mazi. After Xu Jingnan returned to the scene, he found that there were obviously a lot more stones falling off here, and he had taken photos before, and compared them, and sure enough, there were slight changes in many positions on the top of the mine, and it seemed that the structure here was still affected by the blast wave, and it was no wonder that the coal mine wanted to stop production and abandon it.

There doesn't seem to be anything new to be found here, Xu Jingnan continued to walk inside, the mine was getting darker and darker, and it was getting colder, Xu Jingnan gritted his teeth and walked slowly, it was not easy to come in, he hadn't gotten what he wanted to find.

In Mine Three, he failed to find any trace of the butterfly spirit, which did not match the rumors of the miners. In particular, according to mine manager Mei Yuanzheng, after each explosion, there are ghostly butterflies, and the locals also suspect that the butterflies caused the explosion. But there is indeed no No. 3 mine, so Xu Jingnan needs to continue to verify it in the No. 2 mine, if there is no here, the so-called legend of the butterfly elf seems to be just a coincidence, or it is artificially created to hide from the world.

When he reached the deep position of the well, there was no light at all, and he could only rely on a flashlight, and in the sound of the wind, the keen Xu Jingnan really heard the unusual movement. It seemed that something was crawling, and it seemed to be a low roar, Xu Jingnan continued to search on the rocks on both sides with a flashlight, which had been in the dark all the time, and theoretically said that there should be no animals and plants to live. Suddenly, he saw a huge black butterfly resting on the cave wall on one side, and with just a glance, Xu Jingnan was sure that the appearance and form of this butterfly were very similar to those found in the No. 1 mine. The biggest difference between the faces is deformed and distorted, and the wings are covered with holes, but the butterfly in Mine 1 has been dead for a long time and has become a specimen, and this butterfly is still crawling slowly, its wings flapping lightly, hitting the rocks, so it makes a strange sound.

Xu Jingnan quietly walked up, no one expected that the legendary ghost-faced butterfly not only existed in it, but was actually alive! The butterfly seemed to be dazzled by the light of the flashlight, fluttering, but it was powerless to fly, and could only barely squirm. Xu Jingnan took out a professional handkerchief and a sealing bag, saw the right time, caught it without hurting the butterfly, and then sealed it directly in the bag. As a forensic doctor, Xu Jingnan has performed countless autopsies, and he has long been accustomed to many terrifying and disgusting scenes, but even so, he still has lingering palpitations about the strange appearance of butterflies and his body full of holes. After getting the target, Xu Jingnan immediately withdrew from the mine and rushed to the police station, intending to immediately conduct a comprehensive examination of the larvae and butterflies found.
