"The deceased's name is Geng Yaai," Zeng Ke read to the information, "a native of Baiping Town, Beigang City, 16 years old this year. I ran away from home a month and a half ago and haven't returned!"

"Baiping Town?" Zhao Yu opened the map on his mobile phone and checked it, quickly found the location, and said, "It's more than 100 kilometers away from Wuqing County!"

"I'll just say it!" Cui Lizhu rubbed her palms nervously and said with a solemn expression, "Only a perverted murderous demon would do this, kill people, and put them in hanging coffins!" It's so cruel......"

"Since ......that's the case," Zhao Yu said to Miao Ying, "Team Leader Miao, let's go our separate ways! You take Zeng Ke and Cui Lizhu back to the Wuqing County Criminal Police Team, first go to investigate the situation of the deceased, and find out the identities of the other deceased! Since there is one match now, there may be more matches!"

"Understood!" Miao Ying nodded in agreement, "then...... Don't forget to be the first to notify me if there's news from the autopsy!"

"Okay! don't worry......"

Zhao Yu explained two more sentences, and then let Miao Ying and the others go back to the police station first.

Call......

That's right!!

After the person left, Zhao Yu first sighed heavily, and then involuntarily glanced at the hexagram opened today, but saw that the system interface was prominently written - the word "Kungen"!

Kungen!

Kun represents the big thing, and Gen represents the case.

Through Zhao Yu's understanding of the system, this is a standard big case hexagram.

This hexagram was driven by Zhao Yu on the way to take the high-speed train after learning about the case. In other words, he had already expected that the hanging coffin case was by no means an ordinary case!

It has now been proven that one of the deceased in the hanging coffin case was a missing girl. Then it undoubtedly shows that the probability of the girl being murdered is very high!

If these seven girls were all murdered, then this case is no less than the headless female corpse case, or the demon case!

Moreover, the deceased were all underage girls, and the nature of this case is obviously worse!

Who is it!?

Who would have killed these girls? And chose the strange way of hanging the coffin to hide the body?

Murderer...... Why?

"Team leader!" At this time, Ran Tao came to Zhao Yu with a middle-aged man in his 50s and introduced, "This is Pang Zhihui, the president of the Wuqing County Cultural Relics Protection Association, or ...... Well...... The head of the county cultural relics bureau and the deputy director of the county museum!"

"Don't, don't...... Leadership...... Don't be so polite!hehe......" Pang Zhihui hurriedly waved his hand and said, "Our Wuqing is a small place, in fact, the museum, the Cultural Relics Bureau and the Cultural Relics Protection Association are all one unit, which is the same thing!"

"Team leader!" Ran Tao said, "Chairman Pang just led me and my colleagues from the technical team around, and except for the half-dug power pole pit, I didn't find any particularly obvious traces!"

"Oh...... Say ......" Zhao Yu nodded and asked, "President Pang, do you think that the murderer didn't fall down?"

"No, no, no...... I'm not sure......! Leader, come to ...... Come and take ......a look," Pang Zhihui said, he took the lead to a certain place on the edge of the cliff, pointed to an inconspicuous place on the ground and said, "Look, these small holes sealed with cement were all used to fix scaffolding when we first conducted scientific expeditions in the 80s!"

"Whoa......," he said, pointing to the people who are now working, "just like there, we used this method to go down in the first place!"

Zhao Yu squatted down and took a closer look at the small holes sealed by the cement, after a long time of wind and sun, the cement almost merged with the rock, if you don't identify it carefully, you can't see it at all.

"I understand!" Zhao Yu said, "There are seven hanging coffins on the cliff wall, and the positions of the hanging coffins are different! Therefore, if the murderer wants to use scaffolding to go down and release people into the coffin, then he has to change seven different positions, so that it will leave very obvious traces!"

"Hehe...... "Hey Chairman Pang nodded and praised, "A leader is a leader, I don't think I can say it clearly, but you understand it all when you hear it......!

"What if...... There is no need to install scaffolding and lifts," Zhao Yu asked, "Is there any other way to go down?"

"This ......" Pang Zhihui thought for a while, "There are many hanging coffins and cliffs in Wuqing Mountain, but every time we conduct scientific investigations, we use this method for the sake of safety......!

"Yes!" Zhao Yu pondered, "The murderer is not a person, he has to carry at least a dead body on his back, and he also has to open the coffin board......! This coffin board...... Is it easy to open?"

"Of course it's hard to open!, but ...... It's not hard to open!" Pang Zhihui said embarrassedly.

"What kind of nonsense are you?" Ran Tao urged, "Is it good to open or not to open?"

"It's not difficult to open it if you master the essentials," Pang Zhihui hurriedly replied, "But if you can't master the essentials, you won't be able to open it at all!"

"Oh, what do you say?" Zhao Yu asked.

"There are no nails, no wooden wedges!" Pang Zhihui introduced, "I'm afraid you can't imagine that this coffin is from 600 years ago, but it is indeed a slippery lid!"

"Huh?" Ran Tao was speechless, "Isn't it a flat one?"

"There is a fixed slide between the coffin and the coffin board, but there are several exquisite wooden tenon structures set up on the slide, and only if you know how to disassemble the wooden tenon, you can open the hanging coffin!"

"Is it so high-tech?" Ran Tao was surprised.

"The wisdom of the ancients is far beyond our imagination!" Pang Zhihui smiled slightly, "The leaders don't know, this seven-star hanging coffin is different from the other hanging coffins in Wuqing Mountain! Our other hanging coffins are all in 2000, the earliest, and can even be traced back to the primitive society!"

"However, these seven hanging coffins on the banks of the Baisha River are different! They only have a history of more than 600 years, which can be regarded as relatively young among the ancient hanging coffins in the country!" Pang Zhihui said eloquently, "These seven coffins are suspended on the cliff, showing an obvious pattern of the Big Dipper, which is really rare."

"We also found out that the plates of these seven coffins are not the same as other hanging coffins...... As soon as he mentioned the profession, President Pang's eyes suddenly lit up, and he raised four fingers excitedly, "Cypress, pine, willow, and sandalwood!"

"Sandalwood!" Ran Tao said without thinking, "I often hear people say that sandalwood is the best board for coffins!"

"Yes, yes, but not all right!" Pang Zhihui smiled mysteriously and said quite complacently, "The Seven Star Hanging Coffin is indeed made of sandalwood, but through our testing, it has been confirmed that this sandalwood is already in a semi-petrified state!"

"We have detected a variety of compounds and unknown chemicals on the samples!" Pang Zhihui gushed, "Some experts suspect that after the Seven Star Hanging Coffin was made into a coffin, it was soaked in some kind of liquid similar to tung oil for a long time before it became what it is now!"

"So, let's say that in another thousand years, that is, in another ten thousand years, this hanging coffin will not be eroded by wind and rain!"
