Excitement is excitement, but when Zhao Yu was about to open the box, he still hesitated deeply, almost inevitably remembering the nightmarish scene that had happened when he opened the metal box buried by Tao Xiang under the grave.

Every time he thought about it, he felt his hairs stand on end, and he was terrified, and it took a long, long time before he gradually got better.

That, this time...... Will it repeat the mistakes of the past?

Don't forget, the last time I found the head of the treasure chest, I also opened the "Kun" hexagram, and this time I saw the "Kun hexagram" again, will it ......

Who knows, Zhao Yu hesitated, but Cui Lizhu was different. Although she was also one of the parties who saw the head at the beginning, her reaction at the moment was completely different from Zhao Yu's, and after bringing the box over, she almost did not hesitate to reach out and pull the lock of the suitcase.

"Hmm...... You ......"

Zhao Yu wanted to dissuade her, but Cui Lizhu's movements were very fast, and with the sound of stabbing, the old suitcase was opened by her.

In the next second, the two of them saw the contents of the box clearly at the same time.

"I'm going to click, won't I?" Seeing the contents inside, Zhao Yu couldn't help but let out an exclamation, "This ...... What is this?"

He never imagined that there was neither horror nor dazzling things in it, but ...... It's some books that look like they've been around for a long time, and some clutter that has been dusty for years.

"These ...... These ......" Who knows, Cui Lizhu's reaction was different from Zhao Yu, she reached out and grabbed a broken rag doll, and muttered, "This...... I think it's a toy I used when I was a child, and I still have some impressions of ......it!" she picked up a pencil case again, "This is what I used when I was in school, I don't want to throw it away, once it's old, my dad can repair it like new, he ...... He even kept it for me!"

As she spoke, she took out a very ordinary photo album and flipped through it.

Oh......

Zhao Yu first looked at the stone pier and hammer next to him, and then remembered Cui Lizhu's reaction before, and then finally realized: "Oh...... Little girl, play with your boss, this is! you...... You already know what's in this box, right?"

Seeing Cui Lizhu's noncommittal, Zhao Yu patted her head depressedly and scolded: "Okay, you shrewd ghost, you've been making trouble for a long time, you are using me as a coolie who doesn't need money!"

"Hehe......" Cui Lizhu smiled evilly at Zhao Yu, and in the next second, she stared at the photos on the album and watched it intently.

Zhao Yu looked over, but saw that the front were some old photos, some of which were still black and white, and the age was quite old.

"I guess......" Cui Lizhu said, pointing to a group photo, "these...... They must all be my dad's brothers and sisters, right? Look, this one...... Isn't that Li Fei?"

Through the reminder, Zhao Yu suddenly became interested, and hurriedly sat down with Cui Lizhu to watch attentively. But seeing that the person Cui Lizhu was referring to was indeed Li Fei, the murderer of the headless female corpse case.

At that time, Li Fei and Tao Xiang were very young. There were two other smaller men and women next to them, and through identification, Zhao Yu quickly recognized that the man and the woman were Cui Lizhu's biological mother Du Manting, as well as her biological father Cui Fangyu.

"They are all thieves, and they actually take pictures!" Cui Lizhu stroked the photo, her heart was full of infinite emotion, "Aren't they all lightless?"

"Look at this background in a photo studio!" Zhao Yu pointed to the photo and analyzed, "Look at the smiles of a few of them, they are smiling so happily! I think this may be their brothers secretly taking pictures behind their backs!"

Cui Lizhu nodded, flipped back again, and Du Manting's personal photo appeared in the album.

"My mother is so beautiful!" Cui Lizhu exclaimed, "No wonder, my father has been thinking about her all his life, and he can't forget her until he dies!"

"But ......," Zhao Yu said, "you don't look like your mother at all......!

"That's a good thing to say, is it that I'm ugly?"

Cui Lizhu pouted, turned back, and finally, a little girl appeared in the photo, and that little girl was undoubtedly Cui Lizhu when she was a child.

"These photos ...... I've only seen part of it!" Cui Lizhu recalled, "I didn't expect that my father stayed all of them, and now it looks like it's really ...... Alas......"

The old photo touched on the sad thing again, and tears fell from the corners of Cui Lizhu's eyes again.

"Well......" Zhao Yu wanted to comfort her a few words, but suddenly felt that something was wrong, and hurriedly frowned and asked, "Lizhu, your father...... What the hell was I told you at the time?"

"Huh?" Cui Lizhu relieved herself from her memories and asked, "What do you mean? Why do you ask?"

"It's impossible...... Zhao Yu pointed to the box, "Tao Xiang has spent so much effort to bury the box in this hidden place, it should be ...... I don't know if it's for these photos?"

"Well......" Cui Lizhu bit her lip and said angrily, "Detective, don't you get nervous if you don't have a case?"

"My dad buried things here, it's just to bury a precious memory for me! Look at ......" she said, she put down the album and began to pull through the other things in the box, "Oh, it's all books and things I used to do when I was a child, you say, my dad even confessed to the murder, can there be any secrets in this?"

"It's not...... Isn't it ......" Zhao Yu also reached out to look through the books, and said with deep doubts, "I always feel that there should be something wrong!" Lizhu, think about it again, when you mentioned this box, did your father really say nothing......? And also...... This...... What kind of books are these?"

Zhao Yu asked questions, but found that these books were not the same as normal books, some were notebooks, some were manuscripts, and even some were the kind of old-fashioned vertical printing books. He flipped through a few pages, and in addition to the traditional characters, there were many delicate illustrations drawn on them, as if they were industrial drawings.

"Hmm......" Cui Lizhu looked at it and said, "These...... It should be all the secrets left by the thief ancestor, right!?"

"What?" Zhao Yu stammered, "This thing still has an ancestral secret, it's too evil, isn't it?"

"I don't know the specifics," Cui Lizhu said as she looked through the books, "When I was a child, my dad mentioned it to me, but I wasn't very interested. You think, technology is changing with each passing day, and progress is so fast, if you want to become a good thief, you have to keep up with the times. What's the point of learning these ancient books? The locks of ancient times are different from those of modern times!"

"Yes...... But......" Zhao Yu took out another notebook and said, "Look at this book, this book is full of dry goods!"

Cui Lizhu took it and looked at it, and sure enough, she saw that the notebook was densely filled with text symbols, including mathematics, physics, chemistry, and even some biological knowledge. It's just that all of this knowledge has one purpose, and that is that the ultimate goal is to improve the technology of stealing!

"This ......" Cui Lizhu looked at it staggeringly, "This should be my father's notes, this guy...... What a hard work!"

"See, the line is the champion! No matter which line of work, if you want to be the champion, you have to work hard to do it!" Zhao Yu sighed, "I feel that your father will not regard these things as real wealth, and he wants to pass them on to you and let you inherit them, right?"

"Don't ...... Don't be kidding, big brother, I've already changed my ways! When my dad was sober, I had already told her clearly," Cui Lizhu shook her head vigorously, "He also wants to personally thank you for helping me change my ways......!" Well...... But ......"

"But what?" Zhao Yu asked hurriedly when she saw that Cui Lizhu's expression was wrong.

"But...... When you say that, I really remember one thing!" Cui Lizhu said in surprise, "Didn't you just ask me what my father said about this box......? He did seem to have something to tell me, but unfortunately, he was no longer able to do it at that time, and he couldn't remember it without finishing speaking, and at that time, he kept his mouth open, as if he was in a hurry......

"Could it be ......" said Cui Lizhu looked at the box again, "Could it be ...... Is there really anything important in this?"
