"There's a reaction!" Luo Chuan said excitedly.

After Luo Chuan opened the electronic screen, he found the function of analysis and laboratory in it, and after clicking on it, the electronic screen projected a row of light blue virtual light on the inner wall of the mezzanine, and Luo Chuan tentatively put the bag of evidence into the range of virtual light mapping.

I only heard the sound of the electronic screen dripping, and the note began to read on it.

"Analyze Progress...... 30％”

"Has technology developed to this point now?" Luo Chuan said in amazement.

"It's high-tech, it's just cool. Lin Baizhou enviously reached out and touched Luo Chuan's suitcase, and then squatted aside and waited for the results to be generated.

After the progress bar is full, the electronic screen will map the analyzed data to the inner wall of the right mezzanine by projection.

"Chang Zhenghao, male, 31 years old, born in June 1989, from Shanghai, blood type B, no obvious abnormalities in blood. ”

A row of data on the inner wall gradually appeared, and Luo Chuan hurriedly took out his notebook and wrote it down.

"This is really Chang Zhenghao's blood, and it takes no effort to get it. Luo Chuan smiled slightly.

"However, even if you know that it is his blood, you can't find anyone else, and in the end it's still useless. Wei Yusi said dejectedly.

"No, it's a very big finding. Luo Chuan shook his head and said.

"Why?" Lin Baizhou and Wei Yusi asked at the same time.

"Because this is the first direct clue that points to Chang Zhenghao, no matter what can be obtained through this clue, it is better than nothing. ”

"Besides, don't you think it's strange to look at the distribution of blood stains in the corner?" Luo Chuan asked.

"I don't think it's strange. Wei Yusi shook her head bluntly.

"Hmm...... Why did the blood stains disappear all of a sudden?" Lin Baizhou pondered for a moment, then said with a frown.

"Good!" Luo Chuan nodded.

"From this bloodstain, we can draw several questions. ”

"1. Why was Chang Zhenghao injured, who was the person who injured him, was it Tang Jinglong, or was it because of other reasons. ”

"2. Judging from the distribution of blood stains, the extent of Chang Zhenghao's injuries should not be serious, because the amount of bleeding is very small. ”

"Of course, it's also possible that the first scene of his injury wasn't here, and by the time he got here, it was probably under control. ”

"Why did you come to the conclusion that he didn't bleed much? Is it just because there is less blood here?" Lin Baizhou couldn't help but interject and asked.

"You see, it's obvious that the blood is dripping drop by drop, and the distance between the two drops of blood is not particularly close, which shows that the speed of bleeding from the wound is actually not fast, otherwise the distance between the blood stains should be very dense. ”

"Ah, yes, when you have a nosebleed, the blood drips quickly, and the distance between the blood droplets on the ground is very dense. Lin Baizhou suddenly realized.

"Well, 3. That's the question you just asked, why did the blood stains disappear all of a sudden, what method did he use, and why did he deal with it after leaving a trail of blood?"

"If you don't even know what problem you want to solve, you will be arrested, and even if you succeed, you will experience a lot of twists and turns. ”

"Well, you have a point. Lin Baizhou gave Luo Chuan a thumbs up in admiration.

"So, now it's time to address the first question. Luo Chuan smiled confidently.

"Okay, let's go. Lin Baizhou shook his legs, which were a little numb, and then pulled Wei Yusi up.

"You guys go back first, go to Tang Jinglong's side, you guys are not very good with you, and there are some things they can't reveal casually. Luo Chuan looked at the two people in front of him and said.

"No, I want to go with you. Wei Yusi immediately pleaded and said.

"Obedient, I really can't do it this time, I'll come back to you when I'm done, okay? Luo Chuan rubbed Wei Yusi's little head and said.

"I ......" Wei Yusi originally wanted to say something, but as soon as he raised his head and met Luo Chuan's doting eyes, all the attacks seemed to have turned into nothing in an instant, and his face was slightly red and he nodded instinctively.

"Then we'll go back first, and you should be safe. Lin Baizhou clenched his fists and quietly pinned his head over.

"Okay, see you later. After Luo Chuan finished speaking, he walked forward alone until he left the alley and disappeared from their field of vision.

After separating from Lin Baizhou and the others, Luo Chuan dialed Wang Yue's phone and asked her for Tang Jinglong's contact information.

After contacting Tang Jinglong, Luo Chuan proposed to meet with Tang Jinglong to chat, and after learning of Luo Chuan's intention, Tang Jinglong immediately agreed happily, and made an appointment with Luo Chuan to meet at room 307 of Jiuyi Hotel at three o'clock in the afternoon.

Luo Chuan looked at the time, it was two o'clock in the afternoon, although it was still early, but it was better to go a little earlier, otherwise there would be nothing important now.

"Bloodstains...... Wounded...... Disappearing"

Luo Chuan muttered these keywords as he walked, and his brain was running rapidly at the same time.

After a while, Luo Chuan stopped and looked up, and the Jiuyi Hotel appeared in front of him.

Luo Chuan was hesitating whether to go in, because it was not yet half past two in the afternoon, and there was still half an hour before the appointed time, and just when Luo Chuan was hesitating, he happened to see Tang Jinglong walking out of the hotel.

"Hahaha, Brother Luochuan, I came early. When Tang Jinglong saw that it was Luo Chuan, he hurriedly greeted him with a smile.

Tang Jinglong's temperament is relatively straightforward, and his own ability is also very strong, he has more or less solved many cases, and he is a very good policeman.

He doesn't care if you are older than him, he only looks at your ability and personality, and whether you can be recognized by him.

Since learning about Luo Chuan's deeds from Liu Zhenhui, Tang Jinglong has developed a strong curiosity about Luo Chuan, and after seeing Luo Chuan, his behavior and meticulous observation and reasoning ability also made Tang Jinglong sigh to himself.

"Well, I wanted to walk around, but I didn't expect to come over by chance. Luo Chuan also nodded in response.

"Let's go, I'll take you there first, they haven't arrived yet. ”

"Good. ”

Tang Jinglong took Luo Chuan to the door of 307, and after unlocking the access with the room card, he pushed the door and walked in.

"Why is the Boss back? uh... Who is this little brother?"

"He is the little brother of Luochuan that I just mentioned to you. Tang Jinglong pulled Luo Chuan in front of them and said.

"Hello!" a man who looked to be in his early thirties held out his hand to Luo Chuan in a friendly manner.

Luo Chuan naturally didn't dare to slack off, and after the two shook hands, Luo Chuan looked at Tang Jinglong and smiled a little embarrassed.

"Hahaha, don't be nervous, just be casual with them, anyway, one is more shameless than the other. Tang Jinglong said with a laugh.

In fact, Luo Chuan is not nervous, but in this room... The thick smell of stinky feet almost made Luo Chuan feel suffocated.

Luo Chuan walked to the window, opened the window a small slit, and then symbolically leaned on the window to look at it a few times, and then sat on the windowsill.

"Well, the ventilation here is not bad..."Luo Chuan breathed a sigh of relief.

"Have all the people arrived?" Tang Jinglong looked at the time.

"Report boss, it's not here!" said a man with a hippie smile standing up.

"Where did they go, and why haven't they come back?"

"Didn't you say that the meeting was at three o'clock, it was only two forty-five, and they might go down to buy food. ”

"Okay, that's waiting. Tang Jinglong nodded apologetically at Luo Chuan, Luo Chuan naturally didn't say anything, he was originally early.

In about ten minutes, the people who went out to buy food also came back one after another, Tang Jinglong cleared his throat and stood up.

"Regarding Chang Zhenghao's case, we have been following up and investigating it for four days. ”

"Well, it's exactly four days, and it started at three o'clock in the afternoon. ”

"Chang Zhenghao is very cunning, he has escaped our pursuit several times, and I believe that you are all holding a breath in your hearts, right. ”

Everyone clenched their fists tightly, and naturally put away their jokes at this time, and their expressions were slightly unnatural.

"This Luochuan brother is a reinforcement sent to us from above, and I hope that everyone will work together to capture Chang Zhenghao, instead of engaging in individualism. ”

"Although Brother Luochuan is young, I dare to say that his ability to solve the case is no worse than that of you from the police academy, so I don't want any of you to have those disobedient thoughts......
