"Actually, what we can't understand the most is..." Pang Zhihui was still talking about his professional knowledge with relish, "We never thought that the coffin was empty! There was nothing!

"I have been involved in the excavation of hanging coffins for so many years," he said with his hands spread out. "Even if the corpse is rotten, there are still some residues of teeth, hair, etc., but... the seven coffins are empty, not even a little residual corpse oil, as if they have never been filled!"

"Will that... be... robbed?" Ran Tao asked, "Will such a good seven-star hanging coffin attract to grave robbers and clean up the things inside... well... too..." Unexpectedly, before he finished asking, he denied himself, "Where can anyone get the body away?"

"Yes! Tomb robbers are not so clean!" Pang Zhihui said, "The hanging coffin itself is an unsolved mystery, while the seven-star hanging coffin is undoubtedly a mystery in the mystery!"

"It's quite evil!" Ran Tao scratched his head and asked Zhao Yu, "Team leader, do you think this hanging coffin case will be related to some Feng Shui secret techniques? Is it because someone is using hanging coffin to refine corpses?"

"No way?" Pang Zhihui frowned, "In order to develop scenic spots, we had conducted a large-scale civil survey on the seven-star hanging coffin, but it has been blank so far. No one knows the origin of the seven-star hanging coffin!

"Also, we locals are in awe of the hanging coffin, and no one dares to make an idea!"

"So..." Ran Tao raised his eyebrows, "Isn't the murderer a local?"

While talking, Ran Tao suddenly saw Zhao Yu bent down and looked down at the cliff again. Because Zhao Yu bent down too much, Ran Tao quickly reminded: "Hey, boss, be careful! Although there is water below,..."

He wanted to say, "But if it falls down, it's over." But as soon as he thought that this was too unlucky, he quickly stopped.

"The cliff wall... isn't it vertical, right?" Zhao Yu looked down and asked without being moved.

"Yes! Yes!" Pang Zhihui hurriedly replied, "The cliff wall is tilted six or seven degrees inward, wide at the top and narrow at the bottom. The cliff is 67 meters high in total, and the hanging coffin is located between 20 and 40 meters!

"In this way, even if there are any rocks falling on the cliff, the hanging coffin below will not be injured!" As he said that, Pang Zhihui clenched his fists, "But unfortunately, the one that fell yesterday was a telephone pole! The telephone pole rotated in the air and hit the corner of one of the hanging coffins! It's really...ah..."

"President Pang, you can't say that!" Ran Tao said, "Although he damaged a little cultural relics, he discovered such a big case, which is a blessing in disguise! Otherwise, these poor girls would not know that they would be discovered by people in the Year of the Monkey and Horse Month?"

"Well... leader," Pang Zhihui seemed to have thought of something and asked nervously, "How is it? Have you found out that the identities of those girls? They... they are not killed by someone, right?"

"Well..." Ran Tao wanted to answer his question.

However, Zhao Yu suddenly interrupted: "You don't need to know this! I think, let's think about how the murderer transported the body into the hanging coffin!

"President Pang..." Zhao Yu pointed to the bottom of the cliff, "You said, since the mountain is tilted inward, that is, no one can climb up from below?"

"Well... it's almost the same!" Pang Zhihui said nervously, "I feel that even if someone can climb, it's impossible to climb up with a dead body?"

"Indeed, although it's a little girl..." Ran Tao shook his head, "but it's also a bit heavy! Just climbing up like this... is it a bit too incredible, right?"

"There is water under the cliff..." Zhao Yu stretched his neck and looked at it, "It is unlikely to use a machine! But... Ran Tao..." He instructed Ran Tao, "I will find some experts in climbing to consult later!

"And, take people to the bottom of the cliff to check it out yourself. If someone climbs the rock, what marks should be left on the mountain!"

"No, no, no..." Unexpectedly, Pang Zhihui shook his head and said, "The leader doesn't know anything, but he doesn't know anything! The entire mountain here is structural granite, and granite is one of the hardest rocks. It takes a lot of effort to dig a hole with manpower alone!"

"But I heard that when climbing, you don't have to dig a hole. You can use the cracks in the rock to install a rock wedge fixture!" Zhao Yu retorted.

"Leader, I'm telling the truth!" Pang Zhihui said politely, "There is no one in Fulai Province who knows the seven-star hanging coffin better than me!

"There are no cracks under the cliff!"

"Ah?" Zhao Yu was surprised.

"There is another point. As the name suggests, the Baisha River contains a lot of white sand!" Pang Zhihui pointed to the river water below and said, "So, on the side close to the cliff, the river water is very, very shallow, and it is full of sand. The cargo ships in the river are worried about being stranded, so they usually avoid it from the distance!

"If someone really dares to climb rock climbing, then once they fall down, they will definitely die! So..." Pang Zhihui said seriously, "Rock climbing is almost a very strange term for us!"

"Tsk tsk...tsk tsk..."

Although Zhao Yu doesn't like Pang Zhihui's way of speaking very much, he has to admit that people are right.

So he finally pulled back, left the cliff, and turned his gaze elsewhere.

At this time, the staff were changing the position of the scaffolding to prepare to go down to the second hanging coffin.

Seeing this scene, Zhao Yu thought about it and said to Pang Zhihui again: "President Pang, what did the engineering car that installed the telephone poles look like yesterday?"

"Well... they are all yellow!" Although Pang Zhihui didn't know what Zhao Yu meant, he still answered quickly, "One car is equipped with an impact drill bit and is responsible for making pits, while the other car has a telephone pole and is ready to insert the pole!"

"Is it big?" Zhao Yu asked again.

"It's not particularly big..." Pang Zhihui stretched out his hand and gestured, "It's like an ordinary small excavator!"

"You said..." Zhao Yu thought, "If the scaffolding and lift were fixed on those two cars, could those two cars bear it?"

"Ah? So...this is this?" Pang Zhihui finally understood and hurriedly said, "Leader, you really asked the right person! Do you know? When I was in college, I was actually a major in physics!

"Wait a minute, I can use a computer to calculate it roughly. Is the idea you mentioned feasible..."

As he said that, he actually took out his cell phone and started to calculate. While calculating, he pointed to the scaffolding and muttered: "Suppose the lightest scaffold weighs 50 kilograms, then the elevator can basically be calculated based on 50 kilograms, and then the rope and people..."

Seeing that President Pang was so serious, Zhao Yu couldn't interrupt him, so he had to wait patiently with Ran Tao.

As a result, in less than three minutes, President Pang raised his head and said affirmatively to Zhao Yu: "Leader, no! If the scaffolding and lift are fixed with two large vehicles, then these two large vehicles will be at least one-third larger than the two yesterday!

"And there is another key point," said President Pang again. "The scaffolding must be 100% fixed. If it is not fixed on the ground, it must be fixed on the car! So..."

"So... the driver's level must be particularly high!" Zhao Yu pointed to the unobstructed cliff and said, "Cars must drive to the edge of the cliff!"

"Yes! That's what it means!" Pang Zhihui nodded.

"Ha..." Unexpectedly, when Zhao Yu heard this, he laughed softly, "If this is the case, then things seem to have become simple!"

"Why?" Pang Zhihui and Ran Tao asked together.

"President Pang!" Zhao Yu turned around and pointed behind him, "Is it the only way to this cliff that we came?"

"Right!" Pang Zhihui nodded.
