At half past two in the evening, in the office of the special investigation team at the Wuqing County Police Station.

"Ahh......h

But at this moment, Zhao Yu was still in front of the two-sided whiteboard, thinking seriously about the case.

What is written on both whiteboards is information related to the corpse of Woman No. 7. Although it was late at night, Zhao Yu did not show the slightest sense of sleepiness, his eyes widened, and he was still thinking hard.

There are three main reasons why Zhao Yu is so persistent:

First, he has always felt that he seems to have missed something on the body of the No. 7 woman, and if he can find this missing point, maybe there will be significant progress in the case.

Second, his "Kun Qian" hexagram is still going on and has not yet been concluded, so he very much hopes that all the cases can be resolved before the hexagram is completed.

Because, according to past experience, when the "Kun Qian" hexagram ends, the system will have a short freezing period, and then the hexagram will not be able to be opened!

Third, he used sleeping pills to sleep for two days before, and now he has done Lin Chengye again, and he only feels refreshed at the moment, and it is the time when he is most concentrated.

Therefore, he decided to strike while the iron was hot, correctly solve the problem of the No. 7 female corpse, and completely end this strange case of the female corpse in the hanging coffin.

It wasn't just Zhao Yu who didn't sleep, Wu Xiumin was also doing some auxiliary work, and at this moment, she handed over the latest information to Zhao Yu.

"Team leader, I checked, Pang Zhihui is indeed a member of the Pang family, and he is also the 7th generation heir, so he is indeed very suspicious!

"Why don't you ......," Wu Xiumin said, "let's give him a DNA test too?"

"Don't use it for the time being," Zhao Yu said dryly, "A DNA test is easy to startle the snake." Since he is indeed within the range of suspects, we should dig up this person's information!"

"Team leader, the information I can find out now is limited, if you want to know exactly what happened to him twenty or thirty years ago, you still need to conduct a visit and investigation!

"But," Wu Xiumin said embarrassedly, "as long as we visit and investigate, we will still be startled!"

"Hmm...... Let me think about it again......" Zhao Yu pondered for a few seconds, and then asked, "Xiao Cui was right before, if the scope can be determined, then what if the scope can be determined first? Let's see who the No. 7 female corpse may be? As long as her identity is revealed, it will not be difficult to find the murderer, right?"

"Hmm...... Doctors are collecting information, and I think ......," Wu Xiumin said, "at least we can't search until the list is made, right?"

"That's right, they'll only start investigating tomorrow!" Cui Lizhu rubbed her eyes and said, "Boss, listen to me, let's go and rest quickly! The matter of the No. 7 female corpse can be solved sooner or later!"

"Hmm......" Zhao Yu ignored Cui Lizhu, but said to Wu Xiumin, "Sister Wu, you are also tired, show me Pang Zhihui's information, you can go and rest first!"

"Okay!" Wu Xiumin agreed, "Don't be too late, there are still a lot of things waiting for you to deal with tomorrow!"

Zhao Yu nodded, and Wu Xiumin left the office.

At this moment, in the office, only Zhao Yu and Cui Lizhu were left.

"Alright, Lizhu......" Zhao Yu turned his head to look at the whiteboard and said, "You can go to sleep too!

"Ahh......h By the way, what about Sister Miao?"

"It's still in Xiakou. Zhao Yu picked up the pen, wrote something on the whiteboard, and replied, "I asked Miao Ying to stay there and look at Lin Chaofeng!"

"Lin Chaofeng?" Cui Lizhu pouted and asked, "Could it be ...... Do you suspect that woman has a problem too?"

"A little bit," Zhao Yu said calmly, "In addition to being a little suspicious, I'm also worried that Lin Chengye has a backhand, so it's better to leave Miao Ying there, it's more reassuring!Hmm...... Huh?"

Who knows, Zhao Yu was talking to Cui Lizhu, but in his eyes, he suddenly found something important......

"What?" Cui Lizhu was extremely alert, and as soon as she saw Zhao Yu staring at the whiteboard in a daze, she immediately asked, "What's wrong, boss?"

"This ...... This trace...... Got a problem, right?" Zhao Yu stretched out his hand and pointed to several photos pasted on the whiteboard.

"Traces?" Curious, Cui Lizhu hurriedly came to check, but saw that the photos were all heavy and gloomy hanging coffins!

"These traces ......," Zhao Yu said, pointing to one of the photos, "they were all left by Yue Yongnian when they opened the hanging coffin!

"Oh......" Cui Lizhu looked at the photo and said, "There is nothing wrong?" There are no fresh traces on the seventh hanging coffin, which means that Yue Yongnian and the others have indeed not moved. So, the No. 7 female corpse obviously has nothing to do with them!"

"But......" Zhao Yu asked with his eyebrows, "Have you ever thought that Yue Yongnian and the others used cargo ships and ladders to open the coffin! But if the No. 7 female corpse was not made by them, then how was the No. 7 hanging coffin opened?"

"Huh, yes, why didn't I think about it?" Cui Lizhu scratched her head, "The No. 7 hanging coffin is the highest, more than 40 meters!"

"Moreover, if the No. 7 female corpse is really a person born more than 30 years ago, assuming that she was 16 years old when she died, then when she was put into the hanging coffin, it should still be in the nineties of the last century," Zhao Yu asked again, "At that time...... Where's the ladder truck?"

"That's right!" Cui Lizhu frowned, "That murderer, how can he do it? Unless...... Unless...... They descended from the mountains and went down with the corpses, but ...... That's too dangerous, isn't it?"

"Of course!" Zhao Yuyan said, "Have you found that the murderer who placed the No. 7 female corpse is the same problem as Yue Yongnian, they can't do it during the day!"

"That'...... Then what else is possible?" Cui Lizhu became more and more puzzled, "The key is that Yue Yongnian and they placed the corpse for fraud! But what about the No. 7 female corpse?

"Why, I don't know very well, but ......" Zhao Yu looked at the photo and said, "How did the murderer put the No. 7 female corpse in, but I almost already know!"

"Huh, so powerful?" Cui Lizhu hurriedly asked, "Then don't sell it, right?"

"No, it's not Lao Tzu's style to not pretend to be forced, hehe......" Zhao Yu smiled evilly, pointed to the photo of the hanging coffin and asked, "Xiao Cui, have you noticed?" Although the No. 7 hanging coffin is the highest among the seven coffins, it is from the bottom up!"

"From the bottom up?" Cui Lizhu pondered, "You mean, you should look from the top down?"

"Smart," Zhao Yu snapped his fingers, "Looking down from above, the No. 7 hanging coffin is the closest to the cliff!"

"I think it is precisely because of this different perspective on distance that this has caused the fact that Yue Yongnian and the others solved the other 6 hanging coffins first, thus leaving this 7th coffin!"

"Hmm...... But I still don't understand?" Cui Lizhu frowned.

"Look at these traces of opening the coffin left on the hanging coffin," Zhao Yu said again, "There are no fresh traces on the No. 7 hanging coffin, the traces are already very old, right?"

"However, if you look closely, you will find that there are actually some old traces of opening coffins on the other 6 hanging coffins!"

"I know this," Cui Lizhu said busily, "In '85, wasn't the hanging coffin opened once because of the scientific expedition?

"yes, actually...... If you get rid of the fresh traces left by Yue Yongnian and the others, you will find that," Zhao Yu pointed to the photo and said, "The old traces of the other 6 coffins and the old traces of the No. 7 coffin are all the same!"

"Huh!?" This time, Cui Lizhu finally understood, and shouted in surprise, "You...... You mean, that's where the problem came in!? the scientific expedition."

"Hmph......" Zhao Yu smiled slightly, "Now you know, why am I so suspicious of Pang Zhihui?"
