The three of them took the elevator to the top floor.

"This is the laboratory of Qiyuan Biologics, and our company has named it the 'Compass' laboratory." Qi Yuan spoke eloquently and introduced his laboratory, "At the beginning, I set it up on the top floor, not for anything else, but for safety issues. ”

"Oh? Isn't it inconvenient to escape from the top floor? Hu Zhiyong asked.

Qi Yuan stopped, turned around and showed an evil smile, and said, "There are only machines on the top floor, and most of the debugging is carried out downstairs. If there is an accident, the few people on the top floor will definitely not be able to escape, but the people downstairs will not be affected. If the lab were underground, the whole building would have been destroyed. With that, Qi Yuan glanced at Lu Jiuchuan.

Of course, Lu Jiuchuan understood the meaning of Qi Yuan's words, and also knew that Qi Yuan had lied at the press conference at that time, but he didn't show anything unusual, just pretended to be nothing, nodded and smiled politely at Qi Yuan.

The three of them quickly came to the door of the laboratory, and the moment Qi Yuan opened the laboratory, Lu Jiuchuan and Hu Zhiyong gasped, completely shocked by the equipment in front of them. The entire laboratory occupies almost half of the Qiyuan Building, and the equipment and instruments inside are arranged as exquisitely as the space capsule, and all the places around the wall are made of special metal to form a thick barrier, and the silver pipes on the top floor are densely distributed from the inside to the outside, looking like a compass from a distance, and there is a passage in the middle of the annular pipe, and with the passage looking up, it is a machine similar to a transmission tower.

Coming to the very center of the laboratory, there are two adjacent compartments, both connected to the top "compass" by silver pipes, one of which is completely isolated by the wall, so that the interior is not visible, and there is a radioactive warning sign affixed to the doorway; The other is a bulletproof glass room, which houses a console, a cabinet, and a container resembling a silkworm cocoon, the base of which resembles a thick black and black round boulder.

Qi Yuan entered his fingerprint at the door of the bulletproof glass room, and performed pupil recognition, and the glass door opened.

He pointed to the "silkworm cocoon" and said: "This is the main body of our time machine, which I have also shown to you at the press conference before. ”

"Yes." Lu Jiuchuan responded.

"Mr. Qi, how can this thing help us investigate the case?" Hu Zhiyong asked, for him, the key is to find out the case, maybe he can figure out the case seven years ago.

"Look." Qi Yuan took out a very small 360-degree panoramic camera from the cabinet at this time, and then asked Hu Zhiyong, "Do you know the specific time of death of the deceased?" There is also the specific location of the killing. ”

"The time of death was between 3 a.m. and 5 a.m. eight days ago, because the heating and air conditioning were on in the room at that time, which interfered with the judgment of the time of death. The place of death was Room 503, 5th Floor, Building 1, Zhangshu Community. Hu Zhiyong replied.

"Alas, because to go back in time, it is necessary not only to go back to that point in time, but also to go back to the space of that point in time. Because the earth and even the entire universe are constantly moving, if we only go back to the past, it may even lead to the overlap between the object that travels through and something in time and space, so we need a more specific time. With current technology, it should be accurate to at least 1 hour. Qi Yuan was debugging on the console as he spoke, his movements were neither fast nor slow, as if he was waiting for Hu Zhiyong's more accurate answer.

"Four o'clock in the morning!" Hu Zhiyong's heart is also up and down at the moment, because it is indeed impossible to determine the specific time of death, and can only take a median value.

"Yes, at four o'clock in the morning, the camphor community ......," Qi Yuan finished debugging as he spoke, and picked up the camera in his hand to introduce, "Because the energy consumption required to start this machine is very huge, my company will have to travel a living person to more than 2,000 years ago next year, so we can only use this small camera to save energy." The camera can take a 360-degree picture without blind spots, but only one. There is a biosensor inside, and when it senses the movement of a creature, it will automatically take a picture. However, this camera will only appear in places that your police have not detected at the scene, and the time machine cannot change history. ”

Qi Yuan deliberately emphasized again that a time machine cannot change history.

After carefully putting the camera into the "silkworm cocoon", he closed the hatch lightly, and after a careful inspection, he reached out and waved it back, signaling Lu Jiuchuan and Hu Zhiyong to retreat.

When Qi Yuan pressed the start button, the transmission tower at the top suddenly began to radiate a strange light, and the surrounding silver pipes also gradually brightened as the transmission tower began to change from flickering to dark at this moment, making people feel that there was a wave of energy shuttling rapidly in the pipe.

After a while, when the "compass" at the top had stopped brightening, this energy was injected into the "cocoon" along the silver pipe at the top of the glass compartment, and the "cocoon" began to vibrate slightly. At the same time, the base of the "cocoon" began to emit a series of inexplicable, very harsh noises.

The whole process lasted about five minutes, and after the three of them watched intently as the light faded, Qi Yuan excitedly walked over to open the "silkworm cocoon", and turned around and said, "It's successful." ”

As soon as the words fell, Lu Jiuchuan glanced at the internal structure of the "silkworm cocoon" and thought thoughtfully.

Hu Zhiyong also leaned over and found that the camera was no longer there, so he asked, "Then what should we police do now?" ”

"In Zhan Guoxiang's house, I can't give up any corner of this camera in a carpet search. It may even be embedded in furniture or walls. ”

Hu Zhiyong quickly dialed the number of the bureau: "A panoramic camera is comprehensively searched at Zhan Guoxiang's house, no corner is negligent, and the search will be answered immediately!" ”

"Let's go back to the office first, we'll have an answer soon." Qi Yuan said confidently.

Back in the office, Qi Yuan immediately returned to his position, picked up the pen and began to continue his work, while Lu Jiuchuan and Hu Zhiyong waited like this.

About half an hour later, Hu Zhiyong's phone rang suddenly, and the moment he spoke on the phone, his expression immediately froze. Then, he solemnly walked to Qi Yuan's desk.

"Mr. Qi, thank you very much for spending a lot of money to help us provide clues! Just now, the police officer of our team called and said that a panoramic camera was embedded in the gusset in the corner of the kitchen of Zhan Guoxiang's house, and after importing it into the computer, it was found that there was indeed a photo inside, which happened to capture the side face of the murderer when he committed the murder! Excuse me, boy, let's go! After Hu Zhiyong finished speaking, he bowed to Qi Yuan, and pulled Lu Jiuchuan, who was ignorant, out of the office.

After Qi Yuan saw the two of them close the door, he blinked slowly, and his eyes revealed all kinds of disdain.

……

"Squeak-" With the sound of the door opening, a middle-aged man and a young man entered the office one after the other. Then the middle-aged man sat down in his office chair, and the young man sat across from him, and the two men looked at each other.

"Boy, the source of the creature is not simple!" Hu Zhiyong suddenly remembered something, turned on his mobile phone, and showed the photo of the murderer sent by his colleague to Lu Jiuchuan.

Lu Jiuchuan received the mobile phone and found that although the photo was not taken from a normal angle, it could barely be seen that it was a slightly fat man, wrapped tightly all over his body, with a big beer belly, very thick arms, and a side face, the bridge of the nose was very high, and the shadow of the nose in the light covered his other half of the face. In the photo, he has a fierce look on his face, staring ahead with a vicious expression.

Lu Jiuchuan thought to himself: Presumably Zhan Guoxiang is in front of him, but he can't shoot it because of the angle and the obstruction of the wall.

"Could it be a composite photo?" Lu Jiuchuan reacted and asked Hu Zhiyong.

"No, we got the photos and we let the appraisal team check them, it's a real shot!" Hu Zhiyong paused and continued, "This person is not in our public security database. ”

"It's impossible to judge a person's appearance just by their side face, especially in such an environment."

"Boy, I know you're still suspicious of the Origins, but as it stands, it doesn't look like they did it, because there's really no motive. I have also checked their job fairs in the past few years, and since the establishment of Qiyuan, the company has been recruiting talents in physics, and their channels for purchasing time machine materials are all formal channels, and some of them are even purchased by the local management bureau in person. Qiyuan is the star of Linxin City! Hu Zhiyong looked very emotional, but he was actually very disappointed.

Such a result also shows that Hu Zhiyong's investigation is about to start from scratch again, including the case from seven years ago, and the slightest hint has been extinguished by reality, isn't it?

"But ......" Lu Jiuchuan still didn't give up, because he remembered that Leng Qian said that Zhan Guoxiang's first manuscript was probably already in the hands of Qiyuan Creatures.

"Shut up! Boy, you can go out, and leave the case to our police! Hu Zhiyong suddenly reprimanded angrily, his expression serious and fierce.

Lu Jiuchuan was stunned by this inexplicable anger, he really couldn't understand why Hu Zhiyong was angry, didn't he suspect the Kaizen creatures! Just now he himself was clearly suspicious!

Lu Jiuchuan felt that he had suddenly changed from a serious and reasonable person to a stubborn uncle. He nodded disdainfully, and when he stood up, he deliberately made a slight movement to vent his dissatisfaction, and slammed the door.

Seeing this, Hu Zhiyong's eyes flashed, and he sighed lightly: "Alas, I'm still young." ”
