"What do you mean? I still have to watch you two?" Old Zhang said slowly until he could no longer hear the sound in the corridor. Han Xu and Chengzi wiped the sweat from their foreheads almost at the same time. "Chengzi, Xiao Xiao usually looks very gentle, but when it comes to doing things, he is like a tigress. Do you want to reconsider it?" Han Xu patted his chest in fear, feeling like he had just escaped from a tiger park. Chengzi's thick and black eyebrows almost twisted into two balls when he heard this, but soon relaxed, "I like this number!" Old Zhang shuddered after hearing this, "Chengzi, your brother Zhang is an experienced person. Well, I won't say much about other things, you, just wish yourself good luck!" Old Zhang's words were extremely straightforward, but no one in the office didn't know that he had tracheitis. So Chengzi and Han Xu just passed by and didn't take it to heart at all. "I tell you, if you don't listen to the old man, you will suffer!" Old Zhang gritted his teeth when he saw that the two did not pay enough attention. Orange stuck out his tongue at Old Zhang, "You are only a few years older than us, and you are still an old man? Where are the old men?" Old Zhang pouted and said no more!
"Okay, don't interrupt, Orange, take the little mute back to the dormitory to settle down." Han Xu was about to hand the little mute to Orange, and then said to Old Zhang, "Brother Zhang, please go back to the interrogation room and keep an eye on Wei Daguang. If he has any questions, you should ignore them and wait for me to come back to interrogate him again!" Old Zhang nodded, and then asked in confusion, "Where are you going?" Orange didn't understand what Han Xu wanted to do, and looked over with the same concern. Han Xu smiled and planned to keep it a secret. However, Lao Zhang recalled what happened in the morning and quickly guessed what Han Xu was going to do, "Are you going to find Song Jiaer?" Orange heard what Lao Zhang said and understood, "You don't know, Han Xu, you and Li Le were on a business trip for two days, Song Jiaer was like crazy, she went into the laboratory and hasn't come out for a long time." Han Xu frowned and asked in confusion, "What's the situation?" Lao Zhang also heard about it, and said helplessly, "It's probably because the trace inspection department has not been able to help with the recent cases, and Song Jiaer's fighting spirit has come up again." Han Xu also knew Song Jiaer's personality and temper very well. As long as she was determined to do something, she would work a hundred times harder to achieve her goal. "Alas, this girl is really stubborn and too stubborn!" Han Xu said this, but he couldn't help but feel distressed in his heart. Chengzi was unhappy, "She was helping us solve the case! Even if she didn't have any credit, she still worked hard! You're so hurtful!" Old Zhang also felt that Han Xu was too much, and couldn't help but retort, "I don't think any of you can match Jia'er's fighting spirit, and you still have the nerve to say that she is stubborn, Han Xu, you're too much!" Han Xu just said it casually, he felt more distressed than anyone else, but he didn't expect to be criticized immediately, and hurriedly admitted his mistake, "Look at my mouth, I'm just worried about her." After that, he didn't care what Old Zhang and Chengzi said, and got up and left the detention room. Chengzi's words were on the tip of his tongue, but he had no one to vent to, so he swallowed them back, and then looked at Old Zhang with a blank face. Old Zhang smiled, "Actions are always more convincing than words. Orange, you should learn from Han Xu." The nervous Orange tilted his head, "What to learn?" "When will you get the hang of it?" Old Zhang said, and also left the detention room and walked towards the interrogation room. Orange smiled knowingly, picked up the sleepy little mute, and prepared to go back to the dormitory to catch up on a nap. After not sleeping all night, he was really a little sleepy!
... As for Han Xu, he hurried to the building where the technical team was located! He ran to the second floor in a few steps and came to the laboratory of the trace inspection department. Han Xu took a breath and looked up. There was a note on the door. "No entry for idle people, please do not disturb!" Ha, they really got into a fight! Han Xu knocked on the door impatiently, but there was no response from inside. "Song Jiaer, open the door quickly! It's me, Han Xu!" It seemed that he heard the movement. After a while, the door opened a crack with a "creak". Han Xu hurriedly pushed the door open and saw a tired figure. "Why are you here?" Even his voice was a little hoarse. "How long have you been here? Are you going to die?!" Han Xu asked. Song Jiaer looked back at Han Xu, puzzled, "What's this? I used to stay for a week! Are you here to ask for punishment?" Han Xu was speechless, feeling as if someone had calculated him! But there was no evidence! Song Jiaer laughed out loud, it was the first time she saw Han Xu's anxious look. "How dare I? I heard that you locked yourself in the laboratory, so I came to see!" Han Xu saw that Song Jiaer was fine, and his tone was much gentler, "Are you alone?" "How many people do you need? I'm just doing a few experiments here." Song Jiaer looked at Han Xu puzzledly, as if she wanted to see something from his face. Han Xu, who was always thick-skinned, felt a little uncomfortable being stared at. "Well, did you get anything?" When Song Jiaer heard the topic turned to the case, she immediately became a different person, and her spirit and energy changed! The visible fatigue was swept away, and he said excitedly, "Of course I have gained something, I am not wasting my time here in vain." "What did you gain?!" Han Xu saw that he had successfully changed the topic, and hurried to strike while the iron was hot. "Come and see what this is?!" Song Jiaer took Han Xu's hand and walked to the front of the experimental table, pointing her other hand to the computer screen. It was an enlarged incomplete fingerprint! Han Xu frowned, "Isn't this the fingerprint extracted from that brick?" Song Jiaer's face was full of smiles, dazzling, "Yes, isn't that fingerprint incomplete? I tried many methods and finally extracted a fingerprint with 13 features!" "Really? Is this okay?" Han Xu was shocked, because he knew very well how difficult it was to extract effective fingerprints on a brick with a rough surface. If what Song Jiaer said was true, then it could be a breakthrough in a huge problem!
"Well! I've been up for two nights. Look at this fingerprint on the computer screen. Although it's still incomplete, it already has 13 features, which can be used to identify criminal suspects! How about it? I'm awesome, right?" Han Xu shook his head and had to admire Song Jiaer's perseverance. This kind of work of extracting fingerprints looks easy, but in fact it tests a person's patience the most. "Awesome! You're really awesome!" Han Xu praised sincerely from the bottom of his heart. You know, Han Xu originally took out the brick just to mess around. Although the effect was surprisingly good, because the fingerprint with 13 features was not extracted, it could not be used as evidence in court. In other words, if Li Mingyuan regretted in court and overturned his confession, Han Xu would have no way to deal with him. But now it's completely different. Song Jiaer has put the ironclad evidence in front of Han Xu!
