The determination of this result shocked everyone present.

"Who keeps the key to the glass case?" Chen Yufei asked.

"The keys to all the showcases are in the custody of our department." Yu Qingsheng replied, "We use the key intelligent management system, through RFID electronic tag identification technology, the key is managed in an all-round scientific way. Strict identity authorization is required before a key can be retrieved and returned from the smart key cabinet. The manager is responsible for the effective setting of personnel and keys, and can easily query various relevant information about picking up and returning keys and record the situation of key users in detail. It can also remotely control the key return management through the Internet, solve various problems and events caused by improper key management as much as possible, and realize unmanned scientific management. I am a manager, and after my setting, there are only three people in our department, Mu Qingcheng, Shi Qi and Li Yanshan, who have been authorized by my identity. ”

"We want to find out more about picking up and returning the keys today." Chen Yufei made a request.

Yu Qingsheng then took two policemen to inquire.

Zhong Chun's face turned pale, the treasure of the town hall was stolen, and the curator had an unshirkable responsibility. Zhong Jinxiang comforted him beside him: "Dad, don't worry, figure things out first, there will always be a way to solve it." Gu Hengyu's face was also ugly, and he was rarely angry: "Isn't the monitoring system very advanced, and it is claimed that even a fly can't fly in?" There are so many security guards, what do they eat! ”

"Your security guards should cooperate with each other inside and outside, and guard themselves to steal." Chen Yufei said unceremoniously.

Zhong Chun and Gu Hengyu were stunned again, and the police explained the general situation to them.

"Li Dong has been working in our museum for many years, and he is a very loyal and honest person, I really can't believe that he would do such a thing." Zhong Chun shook his head and sighed, "I really know people and faces, but I don't know my heart." ”

At this time, Yu Qingsheng and two policemen came back, and it is said that the system record information shows that Mu Qingcheng is the only one who took and returned the key to the glass cabinet from the smart key cabinet today.

"Li Dong should be threatened, the person who poisoned the food is the one who really participated in the whole plan." Gu Hengyu's guess and Cheng Yijie's judgment are consistent.

Mu Qingcheng suddenly felt like a mang, Gu Hengyu did not raise suspicions about her, but she had been included in the list of suspects by the police and Chen Yufei before. Coupled with the fact that she was the only one who had access to the key, the suspicion was even greater.

Gu Hengyu immediately noticed that Mu Qingcheng's face was different, and he didn't care about Cheng Yijie's presence, so he walked directly to Mu Qingcheng's side and comforted him softly: "I definitely don't doubt your intentions, no matter what, the person who poisoned you can't be you, I will stand firmly on your side!" ”

"Thank you!" Mu Qingcheng was at a loss, only feeling sour in his heart and dizzy. When Chen Yufei targeted her just now, Cheng Yijie didn't even say a word to defend his wife, he didn't care about himself, but it was Gu Hengyu who gave her comfort and support at a critical moment.

Later, Chen Yufei and the two policemen learned some more information from everyone, and after Shi Qi placed the props, he was also questioned. There is no direct evidence to prove that it was poisoned by Shi Qi or Mu Qingcheng, and Li Dong's girlfriend also needs to be investigated, so everyone dispersed one after another. Mu Qingcheng was still standing in place, she still had expectations for Cheng Yijie, expecting him to say a few warm words, and even take her home, softly and gently.

However, she was disappointed again, Cheng Yijie just told her that he would continue to analyze the surveillance video with Chen Yufei and let her go back to the dormitory by herself, so she left in a hurry, leaving her stunned.

"I'll send you back." Gu Hengyu's warm voice knocked her back to her senses.

"Okay." She answered, and walked outside with Gu Hengyu full of misery.

When he arrived at the hall on the first floor, Mu Qingcheng was surprised to see He Muxuan sitting on the couch for the audience to rest, and He Muxuan also saw her, and raised the corners of his mouth defiantly.

A nameless fire surged from Mu Qingcheng's heart, she asked Gu Hengyu to wait, she wanted to say a few words to He Muxuan alone.

"Are you waiting for Yijie?" She strode in front of He Muxuan and asked with a tense face.

"Knowingly asked." He Muxuan cocked Erlang's legs, becoming more and more presumptuous, "He asked me to wait, saying that he would finish things as soon as possible, and then accompany me to drink." You are really a poor woman, just newly married, you were snubbed by your husband and became a resentful woman in the boudoir, ahahaha. ”

Qi and blood were churning in her chest, but Mu Qingcheng couldn't help but didn't lose her demeanor, she straightened her back, raised her head, her face was cold, and her voice was cold: "You are just an outsider, what qualifications do you have to talk here!" ”

"Miss Mu, please put yourself in your position." He Muxuan said coldly, "The real outsider is you, not me." ”

Mu Qingcheng was slightly stunned. "What do you mean?"

"It seems that Miss Mu's brain is not very bright." He Muxuan sneered, "There are some things that can only be understood, not spoken. ”

Mu Qingcheng was terrified, every word and every sentence of He Muxuan penetrated deeply into her heart, she felt a chill down her spine, and her palms were full of cold sweat. I want to go deeper, but I'm scared and can't explore. She straightened her back, maintained her pitiful pride and self-esteem, and walked away.

Gu Hengyu chased after him, "Qingcheng!" He shouted worriedly, "You look in a bad mood......

"I'm fine." Mu Qingcheng interrupted him, "I'm too tired and want to go back and rest quickly." ”

Gu Hengyu had no choice but to ask, "Where do you live?" ”

"I live in a dormitory at a cabaret theater." Mu Qingcheng replied.

Gu Hengyu was stunned for a moment, and then seemed to react suddenly. "You guys worked so hard to rehearse and perform, and you can't even go home."

Mu Qingcheng was also stunned, and then laughed self-deprecatingly, He Muxuan was right, she was a poor woman who was snubbed by her husband when she was newly married, and she was a resentful woman in her boudoir.

"What are you laughing at?" Gu Hengyu looked at her inexplicably.

Mu Qingcheng shook his head, smiled, changed his face to loneliness, and after a long sigh, he was speechless.

When the car arrived outside the gate of the Song and Dance Theater, Mu Qingcheng was about to get out of the car, Gu Hengyu suddenly pulled her hand, she trembled and wanted to withdraw her hand, but he held it firmly.

"Kiyoshi!" His eyes sparkled strangely, "I can see that you are not happy after you get married, can you tell me why?" ”

What happened at this moment made Mu Qingcheng panic, and the nervousness made her breathless, speechless, and vaguely heard Gu Hengyu open his mouth again: "It may be very inappropriate for me to say this now, but I still decided to say it." When I first heard that you were going to get married, I was very distressed, but I knew that there are some things that cannot be forced, and since you have made your choice, I can only silently bless you. To truly love someone, you must learn to let go and let her get a happy life that truly belongs to her. ”

He looked at her, his eyes thoughtful, but a small cluster of flames burning hot. Behind the flames, there is a deep loneliness. "I've been watching you secretly and attentively these days. If you really get happiness, I will admit it. But I found that the word 'frustration' was clearly written in your eyes, and I knew that I was not qualified to ask, and I did not dare to ask. But now I really can't help it, his attitude towards you just now, I can't see that he cares about you at all, how long have you been married, it shouldn't be like this. ”

For a moment, she was a little dazed. She knew what he meant, and he knew it as well as she did. She didn't want to say it, and she didn't need to say anything more. Between them, there was no spark in the past, and now it is even more impossible. There are indeed problems in her marriage, but he is not a good person to talk to, and once there is any entanglement, the result will only be cut and straightened out.

Thinking of this, she slammed her hand back with a slam of force. She couldn't speak, or even squeeze out a smile.

Gu Hengyu put his hand on her shoulder again, she instinctively flinched, he lowered his hand and smiled helplessly. "If you don't want to say it, I'm not reluctant. I just hope you can understand that there is someone who has been concerned about you, no matter what kind of difficulties you encounter, he is willing to do his best to share the burden for you and relieve your worries. ”

"Thank you." She said weakly and feebly, "I should go, goodbye." ”

In the museum's surveillance room, Cheng Yijie and Chen Yufei are analyzing the surveillance footage in the corridor on the second floor. "From 7:45 a.m., there was a slight change in the light." Cheng Yijie pointed to the screen and said, "Someone came in through the window, passed through the corridor, and went all the way to the exhibition hall. In addition, after nearly 10 minutes, the light changed again, and someone left the exhibition hall and returned to the corridor the same way, leaving through the window. ”

Except for Cheng Yijie, no one else can see the change in light. Chen Yufei also has good eyesight, but all she saw was the empty corridor, and she didn't see any change in the light. "What the hell, could it be that person who can't do stealth skills!"

"You're right, that guy is invisible." Cheng Yijie actually affirmed Chen Yufei's nonsense, "Do you remember the invisibility cloak researched by Yang Ru's team?" ”

Chen Yufei was stunned. "You mean, the thieves took advantage of Yang Ru's invisibility cloak technology? But wasn't the missing piece of information never found? We speculated that Yang Ru should have separated the data and stored them in the USB flash drive and the laptop respectively, but the laptop had been blown up in the explosion, so the information in the USB flash drive was incomplete. Ji Rongrong said that the backup data may be hidden in the network disk, but we have not found the network disk of which website it is, and others may not be able to find it. ”

"But we all ignored one point before, Ji Rongrong said that after the explosion, Yang Ruxin bought a laptop and re-stored the information for research. After Yang Ru was killed, she once turned on the computer, but she was actually infected with a virus, and all the data was lost before she could find it. Cheng Yijie said, "In several cases that occurred later, it can be determined that Jim had a hacker who assisted him, and now in retrospect, Yang Ru's computer was infected with a virus, which is likely to be done by hackers, and the hackers had already stolen all of Yang Ru's information at that time."
