At four o'clock in the afternoon, the Wuqingshan County Criminal Police Brigade, the temporary office of the special investigation group.

Wuqingshan County is a real small mountain county, far away from the plains, the location is remote, and the scale of construction naturally cannot be compared with big cities.

However, since it is a famous tourist destination, it is still quite good in terms of environmental hygiene. Moreover, the police station here is surrounded by mountains on both sides, and one side faces the water, which can be described as beautiful mountains and rivers, but it is also very elegant.

In addition, although the police station is small, it is well-equipped and has a smooth network, which can basically meet the needs of the work of the special investigation team.

Zhao Yu ...... Why did you come back so soon?" Suddenly seeing Zhao Yu appear at the door of the office, Miao Ying felt very surprised, "I just transported three corpses here, aren't you staring over there?"

"What's the use of staring? After the scene has been surveyed, I let Ran Tao stare there!" Zhao Yu took a glass of water from the water dispenser, and after drinking it, he said, "Now, they have got another lift, and the two of them work together, and it should be completed before dark!"

"Team leader," at this time, Zeng Ke raised his hand in the distance, "I have already sent someone to retrieve the video surveillance near the cliff intersection, and Captain Xiong has also transferred several experienced criminal police from the city to assist in checking the surveillance, it shouldn't be tonight, and the investigation will be completed!"

"Okay!" Zhao Yu said again, "It's best to walk on two legs, and then let Captain Xiong send a group of people to visit the neighborhood, don't miss any clues! As long as we can find the tools used by the murderer, the case will be half solved!"

"Okay!" Zeng Ke received the order and immediately began to set it up.

"Zhao Yu," Miao Ying pulled Zhao Yu aside and asked, "Except to use the scaffolding lift, didn't the murderer have any other way to put the body in the hanging coffin?"

"Impossible!" Zhao Yu immediately told Miao Ying what Pang Zhihui had said.

"That's not necessarily!" Who knows, Miao Ying objected after hearing it, "Have you heard of Stellio?"

"Huh, what is it?" Zhao Yu frowned.

"You haven't climbed a rock before!" Miao Ying clicked a few times on her mobile phone and retrieved a picture from the online shopping page, "This thing is called a gecko climbing rock wedge, which is a kind of holder that can climb on a smooth rock wall, similar to a gecko in principle!"

"Meow meow...... Zhao Yu shook his head in denial, "Don't say anything about geckos first, climbing a rock with a dead corpse on a person's back is a poisonous spot in itself!"

"Hey!" Miao Ying shook her head, "Zhao Yu, you're still a detective! Can you use your brains? Who said that the murderer must have to climb the rock with the corpse on his back?"

"As long as a person climbs up, he can install a pulley from the hanging coffin and pull the body up!" Miao Ying said.

"I'm not a fool, Zhang Peipei's people and the technical team have already confirmed," Zhao Yu spread his hands to defend, "There are no traces of pulleys installed near the hanging coffin!"

"However, in order to lift the body, the pulley does not necessarily have to be installed near the hanging coffin, you can use a cave, or a beam under the hanging coffin, etc.......," Miao Ying added.

"That's the truth!" Zhao Yu nodded and said, "Moreover, I have already asked the people of the technical team to check it all again!" but, ......" He smacked his lips and said, "You know that President Pang Zhihui, right?"

"That guy almost treats the seven-star hanging coffin as his treasure, he himself said that he will go to the hanging coffin at least once a week to check it, he not only knows the hanging coffin well, but also knows the entire cliff like a treasure......!

"Anyway, if something was wrong, he said he would have found out!"

"That'...... What about the hanging coffin itself?" Miao Ying asked again, "What is the explanation? The murderer took such a big risk to put the body in the hanging coffin, probably not to hide people's eyes, right?"

"Lao Pang said," Zhao Yu poured another glass of water, "The seven-star hanging coffin is a mystery within a mystery, and its origin, whether official or civil, has always been a blank!"

"Alas!" Miao Ying sighed, "Wuqingshan is so big, if you want to dispose of a corpse......, it's too easy! It's too risky!?"

"That's right!" Zhao Yu nodded, "Lao Pang also said the same, in the east of Wuqing Mountain, there is that kind of cave-like hanging coffin, and there are more than twenty coffins stacked in a cave!"

"If it's really to cover up the corpse, wouldn't it be safer to put it there? besides, the cave there is much easier to climb than this seven-star hanging coffin!"

"So......" Miao Ying pondered, "Cracking the mystery of the seven-star hanging coffin may also be a direction for us to solve the case?"

"Don't worry!" Zhao Yu nodded, "I've already asked the above to send experts in this area from all over the country to come over as consultants......!

"Hmm......" Seeing that Miao Ying was still frowning, Zhao Yu hurriedly asked with concern, "Meow...... Are you alright?

"Zhao Yu......" Miao Ying said with a solemn expression, "The girl whose identity we have now confirmed has disappeared a month and a half ago!" Miao Ying said, "A corpse has been in a hanging coffin for more than 40 days, it is impossible not to decompose! But those corpses are ......."

"Okay, don't scare yourself!" Zhao Yu hurriedly explained, "The girl disappeared a month and a half ago, it doesn't mean that she was killed a month and a half ago!

"That'...... Are all 7?" Miao Ying's eyes revealed even greater surprise, "All 7 bodies are well preserved, could it be that all 7 girls have just been killed?"

"Well......" Zhao Yu thought for a moment and explained again, "Don't forget Li Fei in the headless female corpse case!

After saying this, the two of them looked at each other speechlessly, and they were both thinking deeply about this almost evil thought: the corpse in the hanging coffin was not corrupt, and it really had something to do with the murder of those girls?

"Hmm...... By the way, don't just talk about me," Zhao Yu waved his hand and asked, "How are you doing here?"

"We confirmed the identity of Geng Yaai, who grew up in a single-parent family," Miao Ying said, "before she disappeared, she had a big fight with her mother and ran away from home in the middle of the night......

"I have already arranged for Wu Xiumin and Cui Lizhu to go to Baiping Town to investigate! Sister Wu is an expert in this area, and it is best for her to contact her family!"

"Oh...... However......" Zhao Yu showed a worried look, because the treasure case had just ended, he felt that it seemed a little inappropriate for the two female comrades to go out to investigate the case.

"Don't worry!" Miao Ying had already guessed Zhao Yu's thoughts, and said, "They are going with half of the criminal police team! In addition to understanding the situation with the family, they also have to investigate the girl's disappearance, and if necessary, they will also cooperate with the Beigang police to act!"

"Oh...... That's good, that's good!" Zhao Yu relieved himself and drank the second glass of water again.

As soon as the water was drunk, there was a sharp knock on the office door, and a police officer ran over to inform Zhao Yu and Miao Ying, saying that the forensic doctor Zhang Peipei asked them to go to the autopsy room immediately......
