Mu Qingcheng couldn't describe his shock. "What is Ji Rongrong's purpose, to avenge her mother?"

"Revenge is one thing, and on the other hand, she probably wants to keep the research data of the 'Invisibility Cloak' for herself. If such valuable information is taken abroad, it can definitely be sold for a good price. You also saw it when I lied to her and wanted to make a deal, she was very excited, but she really didn't know where the full information was. Cheng Yijie speculated, "She conspired with Jiang Lei to kill your uncle, and then killed Jiang Lei to kill her mouth, and used dry ice to confuse the inference of the time of death to create an alibi for herself." Before the explosion, she didn't know that Yang Ru was storing the data separately, otherwise, she wouldn't have blown up the laptop together, and later found that the information in the USB flash drive was incomplete, but it was too late. She copied the information in the USB flash drive, and then secretly put the USB flash drive into the shoe cabinet and framed Jiang Lei. I deliberately said in front of her that the police thought that Jiang Lei had taken the USB flash drive, and she pretended to be very angry, she really knew how to act. ”

"I can't figure it out a little, since Ji Rongrong and Jiang Lei conspired, no matter which of them took the USB flash drive, since the USB flash drive was already in their hands, why did Jiang Lei break into the duty room late at night and ask me where the USB flash drive was?" Mu Qingcheng asked.

"It's very simple, Ji Rongrong didn't tell Jiang Lei that she got the USB flash drive, and Jiang Lei also coveted the USB flash drive. Although they are colluding, it does not mean that they are of the same mind, maybe they are just using each other. Cheng Yijie said.

Mu Qingcheng sounded very reasonable, and asked again: "What method did Jiang Lei use to let my uncle enter the freezer by himself?" ”

Cheng Yijie expressed his guess: "That night, Ji Rongrong deliberately called Zhang Lizhen to ask for someone, so angry that she unplugged the phone line at home, and Zhang Lizhen and Yang Xirou's mobile phones were turned off, so that the outside world could not contact them." In Li Hua's mobile phone call records, there are several calls to Yang Ru, which coincides with what Ji Rongrong said that Yang Ru received mysterious phone calls for several nights in a row, and left after receiving the phone call on the night of his murder. It shows that Jiang Lei has used Li Hua's mobile phone to call Yang Ru many times before, causing him to be nervous. That night, Jiang Lei only had to claim that he had kidnapped your cousin and locked her in the freezer to avenge Li Hua. Yang Ru was so anxious to save her daughter that she could only rush to the freezer in a hurry when she could not verify it by phone, so she did not wear a cold-proof jacket and use a mobile exhaust fan to remove carbon dioxide at 3 o'clock in the morning, and only wore a short-sleeved T-shirt and entered the freezer alone. ”

"That's right." Mu Qingcheng suddenly remembered, "Ji Rongrong's classmates didn't confirm it, Ji Rongrong received a phone call on the way to the conference room, and the time was consistent with Jiang Lei's call record." At that time, she hid Li Hua's mobile phone on herself and secretly made calls to her mobile phone, right? ”

"If you can't even think of this, you're stupid." Cheng Yijie said simply and clearly, "After the explosion, Ji Rongrong asked Jiang Lei to hide in Li Hua's house, and they drank red wine together in the living room that day, Ji Rongrong took advantage of Jiang Lei's inattention, poisoned the wine glass, poisoned Jiang Lei, and then took out the dry ice prepared in advance, and while delaying the decay time of the corpse through dry ice, she opened the window to accelerate the sublimation of dry ice. She has a background in physics, so she naturally understands the physics of dry ice and can calculate the time just right. Once everything is arranged, go back to school and make an alibi for yourself. She is very smart, but it's a pity that the strong have their own strong players. ”

Mu Qingcheng laughed "snort". "You're really boasting."

"I don't just boast, I praise people." Cheng Yijie suddenly grabbed her hand and kissed her on the lips. "Little Orange, you are the most to my taste among the women I have ever met."

Mu Qingcheng retracted his hand in embarrassment, this hateful man had already taken advantage of her addiction. I was about to choke him a few words, but I saw him roll down the car window.

Outside the car window, Ji Rongrong was taken downstairs by Chen Yufei and Zhao Jun and walked towards the police car parked not far away. Chen Yufei knew that Cheng Yijie's car was parked here, turned around, and made a victory gesture to him, and Cheng Yijie replied with the same gesture.

The police car drove away, and Cheng Yijie also drove Mu Qingcheng back to the old glass factory. "Little Orange, I installed the set-top box on the TV in the duty room." Before Mu Qingcheng got out of the car, Cheng Yijie specially explained, "You can watch the TV programs that have been broadcast before, there are many episodes of "Super Brain" in the variety show, if you want to know more about me, you can order the sixth and twelfth episodes of the second season, and the first episode of the third season." ”

"I don't want to know more about you, I'm not interested." After Mu Qingcheng denied it duplicity, he jumped out of the car and ran without looking back.

After returning to the duty room, facing the newly renovated room, the numbers that Cheng Yijie just said naturally appeared in her mind. She turned on her TV and set-top box, began to search for programs with the remote control, and soon found "Super Brain", which was on demand for the sixth episode of the second season.
