Liu Yu and Chen Fa were released on bail pending trial to avoid being detained, and they had just left the city bureau.

Director Qian Feng informed the technical investigators that the technical investigation methods for Liu Yu were withdrawn.

Yao Zhenhua took out his mobile phone to check whether the mobile phone with the location concealment software could operate normally, and whether the positioning was accurate and sensitive.

Sure enough, Ren Zhen, the head of the technical section, is still reliable, and the positioning software he installed is very easy to use and very hidden.

The mobile phone software showed that Chen Fa was walking, and after a while, it showed that Chen Fa was running, but why did he run so fast and for so long?

Oh, I see, it turns out that he got in the car. Common sense analysis shows that Chen Fa should go home, his home is in the direction of Yanlai District, but he went in the direction of Dongshan District.

"Does this kid have to be a double-sided 'spy'? I think I went to report it to my boss. Yao Zhenhua speculated about the nature of Chen Fa's actions.

I always keep this mobile phone, but it's too much time. Yes, go find Youhua.

Yao Zhenhua came to the office of the back office, and the scene in front of him was a little surprised, all the team members were combing through the case files in the office of the back office, and they were busy.

"Master, you're here."

With Hua's voice, everyone turned to look at the door, looked at the captain, and waited for the task.

"Hmm. Chen Fa, this kid, didn't go home, probably reported to the boss. ”

Yao Zhenhua wanted to speak and stopped, originally wanted Youhua to guard his mobile phone and check Chen Fa's movements, but he didn't expect that she was also busy, so let's guard it for the time being.

"Please note that tomorrow, after Nobita and Liu Yan come back, we will have a team meeting as a team. In the time leading up to the meeting, everyone continued to advance the procedures of the case, complete the chain of evidence, and not a single document should be missing. ”

"By the way, Youhua, have you completed the task I gave you?"

"Master, I have expanded the task you have given me."

"Enlarged?" Yao Zhenhua couldn't believe his ears, why did this female disciple love to struggle so much? "Tell me about it?"

"I think it would be better to first express all the possible procedures in the criminal investigation stage, and then summarize each stage, and try to condense the language of the summary, and if you can refine the formula, it will be better."

Yao Zhenhua said in his heart: "Youhua is going to publish a book!" However, her ideas are still quite positive and positive, and if she can turn her ideals into reality, it will be of great help to the criminal investigation work. ”

"The idea is okay, but I don't know how long it will take you to succeed?" Yao Zhenhua asked all the people in the office what they thought.

"It's a bit of a lot of work, and if it's not busy, it might be two weeks." Youhua said that the time is actually still radical, how can it be so fast, not to mention that it has to be refined into a formula.

Yao Zhenhua didn't express his opinion immediately, but thought about it and said, "Master gives you twenty days, if you can succeed, I will support you to focus." ”

"Great!" Youhua was a little excited.

"Don't stand, keep fighting!" Yao Zhenhua said while checking his mobile phone and recording the trajectory of Cheng one by one.

Everyone continued to sort out the files in their hands. Youhua asked while sorting out the dossier: "Master, when I came back this time, my father asked me to ask you to help him study and judge some benefactors. ”

"This is an old thing, and there is a lack of materials, so it's not easy to analyze!" Yao Zhenhua is not prevaricating, but talking about things and telling the truth.

"Master, last time my dad only said a little, this time at home during the holiday, my dad told me a lot of plots, I think these plots are very valuable, but I just can't figure it out, why did my family's benefactor cut off the clues and hide in the land of the motherland."

"Tell me about it?"

Youhua sorted out the dossier and told the benefactor introduced by his father one by one, everyone in the back office, except for Yao Zhenhua, almost everyone else was listening to the heroic story, and Yao Zhenhua was thinking and looking for a breakthrough in the story.

When Youhua finished telling the heroic story, everyone felt unfinished, what a great heroic warrior at this time! "Death squad", "sacrificing one's life to save others", "not expecting anything in return", "deliberately hiding in an ordinary society and being willing to be an ordinary person".

"Great!"

"Hero!"

"What a hero!"

……

Liu Dong, Hao Chunxiao, Yi Siming, the three of them couldn't help but express their emotions one after another, of course, they must have more emotions in their hearts.

"Youhua, a general said that he went to the benefactor's stepfather and the benefactor's biological father, but he didn't find any clues, and even the police station didn't have relevant household registration relocation information?"

"Yes."

Actually, these are also true. Because, at that time, it was nearly 30 years ago, and the household registration system of that era was very backward, and many people's identity information was not true, and some directly changed their names and surnames, but the original identity information was not changed in the original household registration place, and even the change records were not kept in the original household registration information. ”

"In a word, the hukou system was quite chaotic at the time."

"It is because of this confusion that many cases have been delayed and broken through, and they have become unsolved cases."

"The matter of the general's benefactor, perhaps just like those unsolved cases, due to the imperfect implementation of the household registration system, many identity information changes have not been linked to the identity information of the original place of household registration, so the clues have been cut off."

"In this search for a benefactor, there is a key clue that has been overlooked."

"What clues?" Youhua, like everyone, is bright-eyed.

"The general's benefactor, 'Brother Zhuzi', right?"

"Yes." Youhua replied.

"What was the original name of 'Brother Zhuzi'?"

"My dad said that it seems to be called 'Li Tiezhu'."

"Who is the surname 'Li' with?"

"Benefactor Li Tiezhu, originally named Cheng Tiezhu, later due to his mother's remarriage, he changed his name to his stepfather's surname, and Cheng Tiezhu to Li Tiezhu."

"He changed his name, and he didn't get the approval of the new family, but the original family no longer accepted him, so if it were us, we would change to 'Brother Zhu', then what would we do?"

"Oh, Master, I've figured it out! Since you don't accept me, I'm going to stay away from you, so I went to be a soldier, because I recovered from my injuries, and because I couldn't live together, I might change my name and surname, and this time I must have nothing to do with my biological father's family and stepfather's family. ”

"Well, you have figured it out." "Then think about it again, this benefactor, what will his surname be? Why? ”

"His mother's last name!" The people in the back office said almost in unison.

Yao Zhenhua smiled slightly, glanced at his phone, and added: "From beginning to end, we have never been informed that he has any conflict with his mother, so he is likely to choose his mother's surname." ”

"Master, you are amazing!" Youhua raised his hands flat, stretched out his thumbs, and praised his master's hands.

"Don't be too happy, it's just reasoning, not necessarily correct." Yao Zhenhua is calm, but Youhua is emotional, not only because she is a girl, but mainly because this benefactor is too important to their family.

"Thank you, Master!"

"I've got to tell my dad about this so he can be happy."

Yao Zhenhua didn't pay attention to this matter, and his eyes shifted to his mobile phone.

After looking at his mobile phone for a while, he found that Chen was in a stationary state, and Yao Zhenhua marked this location.

"Coco, charge your drone, charge the backup battery, and choose two high-altitude, long-endurance, and long-range control models."

"Yes!"

"Tomorrow, we will report in a unified manner, we will apply for a gun, bring more bullets, and we must prepare body armor and communication equipment ......"

"Team Yao, we have an important operation?"

"Yes." "There may be a lot of unknown dangers in this operation, so everyone should be prepared." "Coco's drone does a good job of reconnaissance." "When the time comes, Liu Dong will be responsible for driving the car and partnering with Coco to do reconnaissance and logistics preparations."

As long as he knew the danger, Yao Zhenhua didn't want Liu Dong to rush to the front line, because Liu Dong's blood was panda blood, unlike ordinary people, he couldn't be injured.

Everyone understood what the captain meant, and of course Liu Dong understood, but he felt uncomfortable, because in the three major teams, except for Captain Yao, Liu Dong's comprehensive ability may be the strongest.
