After Zhang Han returned from prison, he was not in a good mood.

He knew that what Shen Sibo said was not alarmist, in fact, he had secretly checked the boy.

What made him most depressed was that his niece and the boy named Chen Jin were classmates and his niece's crush, and he secretly flipped through his niece's diary, which was full of niece's yearning and admiration for boys.

Zhang Han's feeling in his heart at that time was that the female university was not left.

Zhang Han went to his brother's house once a week as usual, why did he go every week? Zhang Han is also very helpless, he and his eldest brother are 13 years apart in age, so when Zhang Han was not an adult, his parents died one after another, and his eldest brother is like a father and mother to him, and the eldest brother also feels that as long as he has not been married, he has not grown up.

[Zhang Qiao, look at what your brother brought you? As soon as the sister-in-law opened the door and saw what Zhang Han was carrying, she happily called out to her husband.

[Yo, you kid, how do you know I'm hungry for this. The eldest brother came out of the kitchen and saw the crab in Zhang Han's hand, and joked happily.

[Big brother and sister-in-law, when will Meimei come back, she also likes to eat this the most. Zhang Han said with a smile.

[You, like your eldest brother, know that you are accustomed to beauty, and sooner or later you will be spoiled. The sister-in-law smiled and counted Zhang Han.

[It's okay sister-in-law, I've been used to raising her for a lifetime, just right. 】

[Yes, let her uncle raise her for the rest of her life, haha. Zhang Qiao happily echoed while receiving the crab in Zhang Han's hand.

[I mean, you two brothers, Zhang Han washes his hands, and the meal will start in a while, and Meimei will be out of school soon. 】

[Yes, sister-in-law. Zhang Han's fake salute.

Late at night, when the whole family fell asleep, Zhang Han opened the photo album on his mobile phone, which contained the contents of his niece's diary secretly taken in the afternoon.

September 26, 20YY was sunny

I saw Li Jin again when I went to school today, he was still so handsome, and he greeted me with a bright face in the sun. I feel like my face is going to be as red as a monkey's ass again.

I don't know what's wrong with me, Li Jin is there, my eyes are followed there, I can't control it, I can't pay attention to my spirit in class, alas, I like what he likes is incorrigible.

After school, Li Jin went to the old factory near the school again, and I was always curious about what he was doing, but I overheard the discussion of his classmates, saying that he was doing chemistry experiments there, and that he was going to participate in the national chemistry competition for middle school students. He's amazing!

The more I got to know him, the more I felt unworthy of him. Alas.

Zhang Han really couldn't stand the portrait of his niece, thinking that this boy was okay, and he wouldn't belittle the child so much.

But what kind of experiments is this kid doing in the old factory as mentioned in the diary? Zhang Han still muttered in his heart.

He didn't understand the dream he had that night, how could he have been chosen by death? When he came out of the police force, he felt that he was really not suitable to be a law enforcer, so he retreated and opened this detective agency, just to help his old classmates and friends investigate cases, not to enforce the law and enforce any rights.

The worst thing is that the Grim Reaper just let him be in a group with a child, if it was other adults, maybe he would play tricks to let himself win, but boy, he couldn't do it, so he kept hesitating.

Until he saw Shen Sibo's modus operandi, he seemed to be hit on the head, maybe this young man was not as simple as he thought.

Zhang Han looked at Li Jin's file carefully, 16 years old, a sophomore in Baoya High School, the student president, and the father of the family is the head of the security section of a state-owned enterprise, and likes to drink with colleagues after work. And my mother opened a mahjong parlor because she loved to play mahjong.

Seeing this, Zhang Han felt that Li Jin's child should lack family care since he was a child, but he himself was unusually strong, ranked first in his studies since he was a child, was good at thinking, and liked to break the rules, so even if the competition was imminent, he didn't use the school's laboratory, but went to the abandoned old factory to do some tests.

Until one day, Zhang Han saw from his niece Meimei's diary that Li Jin suddenly took the initiative to become friends with Meimei, and invited her to visit his experimental base after school.

At this time, Zhang Han felt bad and wanted to stop Meimei immediately, but looking at the date, Meimei should have been there more than once.

Zhang Han guessed that Li Jin should know that he was Meimei's uncle and took the initiative to get close to Meimei, but what would he do next after he got close to Meimei? Lure him out? But so far even Meimei doesn't know that her uncle is peeking at her diary, and Meimei in adolescence has become more and more rebellious, and she never wants to tell her family about things at school.

Zhang Han fell into deep thought......

The ringtone of the mobile phone exploded, pulling Zhang Han out of his contemplation: [Hey.......]

[Uncle, come and save me? 】

[Meimei? Where are you? 】

The other end of the phone suddenly hung up ........

Zhang Han immediately called his eldest brother [Big brother, is Meimei at home? 】

[No, Meimei called just now and said that she would go home later today and go to play with her classmates. 】

[Did she say which classmate she went to?] 】

[No, after this kid said this, he hung up the phone for me, and now he is becoming more and more rude. 】

[Big brother, call me when Meimei comes back. 】

[Okay, Zhang Han, why do you suddenly want to find Meimei today? Is she doing something bad outside? Zhang Qiao asked suspiciously.

[No, I bought Meimei her favorite figure and wanted to surprise her. 】

[I said, she's back, I'll call you.] 】

Zhang Han asked Su Yong to contact the school's monitoring to find out who Meimei was going to school with in the end.

As expected, surveillance around the school showed that Meimei and Li Jin finally went to the abandoned factory near the school.

But when he and Su Yong came to the abandoned factory, there was no one, only a dilapidated office on the second floor of the factory with several sets of beakers of different sizes, and thermometers, iron shelves, test tubes, alcohol lamps, and flasks on the table......

[Su Yong, does the surveillance really show that they haven't gone out since they came here? 】

[Yes, we didn't dare to miss it for a second, these two children never went out after they got here. It's weird, they can fly? If you can fly, you have to have a shadow. Su Yong asked suspiciously, scratching his head.

[Su Yong, I know you have other cases today, you are busy first, and I will look around here myself. 】

[Old classmates, don't be polite to me, I'll accompany you to find it, let them withdraw first. 】

[No, just two children, it is estimated that they will not run far, today is the suspect you have been checking for a month, and you are going to get out of the hole, don't delay the big thing for this little thing. 】

[Okay, I'm not polite to you, I'll come back to you as soon as I'm done. 】

[Okay, let's get busy.] I'll call you as soon as there's a situation on my side. 】

Zhang Han patted an old classmate Su Yong on the shoulder and signaled that it was really fine.
