At 2:30 in the evening, the Wuqing County Police Bureau was transferred to the office of the special group.

"Oh..." Cui Lizhu, who was lying on the desk, yawned and looked at the center of the office.

But at this moment, Zhao Yu was still thinking seriously about the case in front of both whiteboards.

The whiteboards on both sides were all about the information related to the female corpse No. 7. Although it was late at night, Zhao Yu was not sleepy at all, his eyes widened and he was still thinking hard.

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

First, he always felt that he had missed something on the female corpse No. 7. If he could find this missing point, maybe there would be significant progress in the case.

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

Because, based on past experience, when the "Kun Gan" hexagram ends, the system will have a short freezing period, and the hexagram will not be opened at that time!

Third, he slept well with sleeping pills for two days before, and now he has done Lin Chengye again. At this moment, he only feels refreshed and is the time when he is most focused.

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

Not only Zhao Yu was not sleeping, but Wu Xiumin was also doing some auxiliary work. At this moment, she handed over the latest information she found to Zhao Yu.

"Team leader, I checked it. Pang Zhihui is indeed a member of the Pang family and is also the 7th generation descendant, so it is indeed a big suspicion!

"Or..." Wu Xiumin said, "Let's test his DNA too?"

"Not for now," Zhao Yu said simply, "After testing DNA, it is easy to alarm the snake. Since he is indeed within the scope of the suspect, we should dig out the information about this person!"

"Team leader, the information I can find 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 alert to the enemy!"

"Well... I'll think about it again..." Zhao Yu sank for a few seconds and asked again, "Xiao Cui was right before. If the scope can be determined, then start with the missing person? Let's see who the female corpse No. 7 may be? As long as her identity is revealed, it will not be difficult to find the murderer, right?"

"Well... Forensic Gao and the others are collecting information, I think..." Wu Xiumin said, "At least we can only search after the list is completed, right?"

"Yes, they will only start checking tomorrow!" Cui Lizhu rubbed her eyes and said, "Boss, listen to me, so let's take a break! The matter of the No. 7 female corpse can be handled sooner or later!"

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

"Okay!" Wu Xiumin agreed and reminded, "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, only Zhao Yu and Cui Lizhu were left in the office.

"Okay, Lizhu..." Zhao Yu turned around and looked at the whiteboard and said, "You should go to bed too! There is nothing to do with you here!"

"Oh..." Cui Lizhu stretched and shook her head and said, "No, I'll just watch you here! It's better to help you get some help. By the way, where is 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, "Do you suspect that woman has a problem?"

"A little bit," Zhao Yu said frankly, "In addition to being a little suspicious, he is also worried that Lin Chengye has a backup plan, so it's better to leave Miao Ying there, so it's more reassuring! Well... um?"

Unexpectedly, Zhao Yu was talking to Cui Lizhu, but suddenly something important was found in her eyes...

"What?" Cui Lizhu was extremely alert. When she saw Zhao Yu staring at the white board, she immediately asked, "What's wrong, boss?"

"This...this trace...is there something wrong with it?" Zhao Yu stretched out his hand and pointed to several photos pasted on the whiteboard.

"Traces?" Curious, Cui Lizhu hurried to check it out, but saw that the photos were filled with heavy and gloomy hanging coffins!

"These traces..." Zhao Yu pointed to one of the photos and said, "It was all left by Yue Yongnian and the others when they opened the hanging coffin! Because the coffin board was very heavy, they took a lot of effort!"

"Oh..." Cui Lizhu read the photo and said, "Nothing is wrong? There is no fresh trace on the 7th hanging coffin, which means that Yue Yongnian and others have indeed not touched it. Therefore, the No. 7 female corpse obviously has nothing to do with them!"

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

"Huh? Yes? Why haven't I thought about this?" Cui Lizhu scratched her head, "The 7th hanging coffin is the highest, more than 40 meters!"

"And, if the female corpse No. 7 was really a person born more than 30 years ago, if she was 16 years old when she died, then it should be the 1990s when she was put into the hanging coffin," Zhao Yu asked again, "At that time...where was there any ladder van?"

"Yes!" Cui Lizhu frowned, "How could the murderer do it? Unless... unless... they descended from mountains and took their bodies down, but... that was too dangerous, right?"

"Of course!" Zhao Yuyan said, "Did you find out? The murderer who placed the No. 7 female corpse was facing the same problem as Yue Yongnian and the others. They could not do anything during the day!"

"Then...what else is possible?" Cui Lizhu became more and more confused. "The key is that Yue Yongnian and the others placed the corpse to cheat! But what about the female corpse No. 7? Why?"

"Why, I don't know very well, but..." Zhao Yu said as he looked at the photo, "I almost know how the murderer put the female corpse No. 7 in it!"

"Ah? So awesome?" Choi Lizhu asked hurriedly, "Then don't keep it aside, right?"

"No, it's not my style to behave, hehe..." Zhao Yu smiled badly, pointed to the photo of the hanging coffin and asked, "Xiao Cui, have you noticed it? Although the hanging coffin No. 7 is the highest in the 7-mouthed coffin, it can be seen from bottom to top!"

"From the bottom to the top?" Cui Lizhu thought, "What do you mean is that you should look from the top to the bottom?"

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

"I think it is precisely because of this different perspective of viewing distance that Yue Yongnian and others first solved the fact that the other 6 hanging coffins were left behind!"

"Well...but, I still don't understand?" Cui Lizhu frowned.

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

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

"I know this," Cui Lizhu said hurriedly, "In 1985, wasn't the hanging coffin opened once because of the scientific examination? Of course, they were left at that time?"

"Yes, actually... if you remove the fresh traces left by Yue Yongnian and others, you will find out," Zhao Yu pointed to the photo and said, "The ancient traces of the other six coffins are the same as those of the No. 7 coffins!"

"Ah!?" This time, Choi Lizhu finally understood and shouted in surprise, "You...you mean, the problem lies in that scientific investigation!!"
Chapter completed!
