Feng Mingqing and Mr. Luo did not speak, and sat quietly. About half an hour later, the door of the room that originally belonged to Xiao C opened, and Qin Yu walked out expressionlessly.

"How's it going?" asked Mr. Luo, a hint of anticipation ignited in his eyes, which had been gloomy before.

Qin Yu remembered his identity as an expert in trace science, and in the room half an hour ago, in addition to taking the necessary photos, he had been thinking about how to speak: "Mr. Luo, I hope you don't mind that I took a lot of photos, there are indeed some strange things inside and outside your daughter's room, and I still need to go back to compare and analyze before I can give you an exact answer." ”

"That's no result. The glimmer of hope that Mr. Luo had just ignited was also disappointed. In the past two months, he and his wife have experienced this situation countless times, and they have long been like ashes.

"I'm sorry. Qin Yu bowed slightly, apologetic, but then the conversation changed: "I don't know if you know if your daughter has a hobby of watching live broadcasts on her mobile phone?"

"Live broadcast?" Mr. Luo was stunned for a moment, frowned and thought: "It seems to be, but it doesn't seem to have 。。。。。。 Hey, blame me for being so busy with work that I don't even know about this. Does this have anything to do with my daughter's case?" Mr. Luo still instinctively used the word "case".

"It would be better if we could know the exact answer. I need to take your daughter's phone back and ask the technical department to try to fix it. As soon as Feng Mingqing heard this, he knew that Qin Yu had probably discovered something, and immediately said cooperatively.

"Well, I'll ask my wife, and you'll wait a minute. ”

"Hey, in fact, mother, how can you not know what your daughter is doing. I just know that she studies hard, so I pretend not to know, and occasionally send some food to Xiao C, but also to remind her not to be too addicted, who knows... Mmmmmm Mrs. Law burst into tears as she spoke.

。。。。。。

"What did you find?" Feng Mingqing asked as soon as he came out, he knew that Qin Yu must have known something.

"How can you be sure that I have made a discovery?" Qin Yu asked rhetorically.

"If this is not a simple suicide, then the murderer must be a pervert. ”

"So what?"

"I think you too, perverted thinking is always similar. Feng Mingqing said very seriously.

“。。。。。。 Qin Yu sneered, looking at Feng Mingqing's eyes like a poisonous snake staring at his prey: "If I am a perverted murderer, who do you guess I will kill first?"

Feng Mingqing looked at the sky with his eyes, whistled and pressed the elevator: "Let's get down to business." ”

Qin Yu didn't get into the elevator, but turned around and went up to the eleventh floor, Feng Mingqing knew that there was a play at a glance, and hurriedly followed. The eleventh floor is the top floor, and there is a half-story attic that needs to be climbed by a staircase, and there is a locked iron door on it.

"Turn it on. ”

"I've been to the rooftop a long time ago, and I haven't found any clues. Feng Mingqing shook his head: "And I won't open the lock, I can't open it." ”

"You're a policeman, big brother, won't you call someone to open if you can't open it?"

Feng Mingqing immediately called the property and asked them to send someone to come up and open the door, and the two then stepped on the small platform on the roof.

"Just because you can't find it doesn't mean I can't. Qin Yu walked to the edge of the rooftop and looked down, a little dizzy. He bent down and carefully observed the traces on the roof of the roof, although it had been two months and there had been several heavy rains, Qin Yu, who had come prepared, finally found an anomaly about ten meters to the right of the window of the small C room. After wiping off the dust, you can see very small rope scratches on the edges and corners of the wall, and if you don't look closely, you may think that this is caused by the normal aging of the wall. And this place is far away from the small C window, although Feng Mingqing has carefully searched, he still ignores this point.

"You see the scratches here, they don't form naturally. The murderer should have gone down from here, and then swung out of Little C's window. Qin Yu directly used the word murderer.

Feng Mingqing's face suddenly became a lot more serious, and he also leaned over to distinguish it carefully, and the more he looked at it, the more he felt that what Qin Yu said made sense. He immediately contacted Xiao Li and asked him to bring his tools and hurry over. Then Qin Yu followed the angle of the scratches and went straight to the metal water tank in the center of the roof, and stretched out his hand to gessy.

In order to reduce the degree of abrasion, the murderer should have used a large nylon rope to tie the entire tank to make it evenly forced, and the possible scars were minimized. ”

Xiao Li soon arrived, with a special climbing rope for the police force, and called two special police officers. Several people tied the rope tightly in the way Qin Yu requested, and then tied the other end of the rope to one of the slightly thinner SWAT officers. After testing, although a little embarrassed, through the water pipes on the wall and the outdoor rack of the air conditioner, the SWAT officer still managed to grab the edge of the window sill and landed safely on the outdoor rack below the side.

"So that's the case!" Xiao Li suddenly realized, looking at Qin Yu's eyes full of capital admiration, but he immediately threw out another question: "If the murderer committed the murder like this, then how did he open the window of Xiao C's room from the outside?" At that time, Mrs. Luo said that Xiao C's window was locked all year round, and she also paid special attention to it that night, and it was indeed a state of reverse buckle. ”

Feng Mingqing handed the broken mobile phone to Xiao Li: "There are still many doubts, let the technical department try to repair it first and see if you can find anything." ”

。。。。。。

Saying goodbye to Feng Mingqing, Qin Yu returned to the dormitory, and he was startled as soon as he entered the door. I saw Liu Yuanzheng naked, with a strip of red cloth on his head that he didn't know where to turn out, with the word "Struggle!" written on it, and doing push-ups frantically.

"What are you doing, jerking?"

"I'm going to have a duel in a few days, I have to intensify my training!" Liu Yuan said intermittently, dressed roughly.

"Are you sure it's really useful to crammed like this?" Qin Yu was skeptical about this approach: "I think it's better for you to retain your physical strength, don't get injured before you do." ”

Liu Yuan had words in his mouth, and insisted on finishing two hundred push-ups, and the whole person fell to the ground with a bang, like a hungry dog, constantly sticking out his tongue.

“。。。。。。 Qin Yu was full of black lines.

After lying on the corpse for more than ten minutes, Liu Yuan slowly got up and moved his muscles: "I just bought 30 kilograms of dumbbells, and I will do a few more sets of bench presses later, and we will eat together in the evening, right?"

"I don't think you'd better do it, I'm afraid you won't be able to hold the chopsticks later. Exercising doesn't happen overnight, and there's not much point in strengthening your special training right now. Qin Yu walked to the desk and sat down, sorted out the books he was going to read recently, put them in a separate compartment and said, "You will have military training in a few days, and I plan to take advantage of this time to go out." ”

After getting to know the teachers and classmates briefly, the freshmen of Donghai Art Institute will usher in a half-month military training. And because Qin Yu is an auditor, he has no qualifications for military training, so he can arrange it freely during this time. It just so happened that Ma Ju contacted him a few days ago, saying that he was going to participate in the large-scale autumn jade exhibition held by Yun Province with Xu Laixiang, and asked him if he was interested in traveling with him.

Jade Exhibition, of course Qin Yu is interested. According to Ma Ju, in addition to a large number of exquisite jadeite products, there are also a lot of rough stones for sale at the exhibition. Others buy rough stones, that is called gambling stones, but for Qin Yu, who has an anti-heaven system, what is the difference between buying jade rough stones and picking up money for nothing?
