"Actually, what we can't figure out the most is ......" Pang Zhihui was still talking about his professional knowledge with relish, "we didn't expect that the coffin was actually empty!

"I've been involved in the excavation of the coffin for so many years," he said, spreading his hands, "even if the body is already decomposed, how can there be some teeth left, hair and other residues, but ...... The inside of these seven coffins was empty, and there was not even a little residual corpse oil or anything, as if they had never been filled with anything!"

"Isn't that going to ...... Was it stolen and excavated?" Ran Tao asked, "Will such a good seven-star hanging coffin attract tomb robbers to clean up the contents inside...... Well...... It's also ......" Who knows, before he finished asking, he gave his own negative, "How can anyone rob the tomb take away the corpse?"

"Yes, the tomb robbery is not so clean!" Pang Zhihui said, "The hanging coffin itself is an unsolved mystery, and the seven-star hanging coffin is undoubtedly a mystery within a mystery!"

"It's quite evil!" Ran Tao scratched his head and asked Zhao Yu, "Team leader, do you say, could it be that this hanging coffin case will have something to do with some feng shui secret techniques or something?"

"Wouldn't it?" Pang Zhihui suddenly frowned, "In order to develop scenic spots, we once did a large-scale folk survey on the Seven Star Hanging Coffin, but it is still a blank, and no one knows the origin of the Seven Star Hanging Coffin!"

"Also, we locals are in awe of the hanging coffin, and generally no one dares to fight its idea!"

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

While speaking, Ran Tao suddenly saw Zhao Yu bending down and looking down at the cliff again, because Zhao Yu bent down too much, Ran Tao hurriedly reminded: "Hey, boss, be careful! Although there is water below, it is ......."

He wanted to say, "But if you fall, you'll be finished," but when he thought it was too unlucky, he quickly stopped.

"Cliff ...... It's not vertical, is it?" Zhao Yu looked down unmoved and asked.

"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, and the hanging coffin is between 20 and 40 meters!

"In this way, even if there are any falling rocks on the cliff, it will not hurt the hanging coffin below!" Pang Zhihui clenched his fists as he spoke, "But unfortunately, it was a telephone pole that fell yesterday! The telephone pole spun in the air and hit the corner of one of the hanging coffins......! Alas......"

"President Pang, you can't say that!" Ran Tao said, "Although a little cultural relics have been damaged, it can be regarded as a blessing in disguise that such a big case has been discovered! Otherwise, these poor girls don't know that the Year of the Monkey can only be discovered by people?"

"Hmm...... Leader," Pang Zhihui seemed to think of something, and hurriedly asked nervously, "What's wrong? Have you found out the identities of those girls......? They can't be killed, 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 still think about how the murderer transported the body to the hanging coffin!"

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

"Hmm...... Difference...... Almost!" Pang Zhihui said nervously, "I feel that even if someone can climb, it is impossible to climb up with a dead body?"

"Indeed, although it is a little girl......" Ran Tao shook his head, "but it also has some weight......! It's a little weird, isn't it?"

"There is ......water under the cliff," Zhao Yu craned his neck to look, "If you use a machine, it's impossible......!" Ran Tao......" He instructed Ran Tao, "Later, let's consult with some experts in climbing!"

"And, take someone down the cliff and check it out for yourself. If someone climbs, there should be some chisel marks left on the mountain!"

"No, no, no......" Pang Zhihui shook his head and said, "The leaders don't know something, they don't know anything! The entire mountain here is structural granite, granite is one of the hardest rocks, and it takes a lot of effort to dig holes with manpower alone!"

"But I've heard that you don't have to dig holes to climb rocks, you can use cracks in the rocks to install rock wedge holders!" Zhao Yu retorted.

"Leader, I'm telling the truth!" Pang Zhihui said politely, "In the entire Fulai Province, there is no one who knows the Seven Star Hanging Coffin better than me!"

"Under the cliff, there are no cracks at all!"

"Huh?" Zhao Yu was surprised.

"Another point, as the name suggests, the Baisha River contains a lot of white sand in the river!" Pang Zhihui pointed to the river below and said, "So, on the side close to the cliff, the river is very, very shallow, and it is full of sand.

"If someone really dares to climb rocks, then once they fall, they will definitely die!" so ......" Pang Zhihui said seriously, "rock climbing is almost a very unfamiliar term to us!"

"Tsk...... Tsk......"

Although Zhao Yu didn't like Pang Zhihui's way of speaking, he had to admit that people were right.

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

At this time, the staff is changing the position of the scaffolding in preparation for the second hanging coffin.

Seeing this situation, Zhao Yu's heart moved, and he said to Pang Zhihui again: "President Pang, yesterday ...... What does the engineering truck where the pole was installed look like?"

"Hmm...... It's all yellow!" Although Pang Zhihui didn't know what Zhao Yu meant, he still quickly replied, "One is equipped with a percussion drill bit to be responsible for digging holes, and the other is holding a telephone pole, 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 say......" Zhao Yu pondered, "If the scaffolding and the lift are fixed on those two cars, can those two cars withstand it?"

"Huh......? 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 physics major!"

"Wait a minute, I can now use the computer to roughly calculate whether this idea you said is feasible......

As he spoke, he actually took out his phone and began to calculate. While calculating, he also pointed to the scaffold and muttered: "Assuming that the lightest scaffold weighs 50 kilograms, then the elevator can basically be calculated according to 50 kilograms, and then the rope and human ...... are calculated."

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, Chairman Pang raised his head and said to Zhao Yu with certainty: "Leader, no! If the scaffolding and the elevator are fixed by two large vehicles, then these two large vehicles must be at least one-third larger than the two yesterday!"

"Moreover, there is another key point," said Chairman Pang, "the scaffolding must be 100% fixed, if it is not fixed on the ground, then it must be fixed on the car......!"

"So...... The driver's level must be very high!" Zhao Yu pointed to the unobstructed cliff and said, "The car must be driven to the edge of the cliff!"

"That's right!" Pang Zhihui nodded.

"Ha ......" Who knows, hearing this, Zhao Yu laughed lightly, "If that's the case, then things seem to have become simpler!"

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

"President Pang!" Zhao Yu turned around and pointed behind him, "Is there only the same road leading to this cliff as when we came?"

"That's right!" Pang Zhihui nodded.

"I just noticed that there is a Sky Eye installed under that road!" Zhao Yu snapped his fingers, "So, we just need to check what large vehicles have been on this cliff recently! Maybe the problem will not be difficult to solve!"
