Film and Television: My Cheat Code is AI

When they arrived at Beijing Tongzheng Company in Qianfeng Science and Technology Park, the receptionist led them in. Dong Yinglu was walking out of a laboratory full of servers. He was in his early thirties, wearing glasses, and his shirt sleeves were rolled up to his forearms. He looked like a typical tech-savvy boss.

"You're looking for me?" He took off his glasses, wiped them, and looked at this person and then at that person.

Tian Rui spoke first: "You must be Mr. Dong Yinglu, Liao Jiangqun's fiancé?"

Dong Yinglu nodded, her expression immediately tightening: "Yes, what happened to A-Qun?"

Ji Jie waved her hand casually, "She's fine. It's just that a few of us wanted to consult you about some technical issues."

Dong Yinglu visibly relaxed and turned to the administrator next to her, instructing, "Bring over three glasses of water."

"Okay, Mr. Dong."

After entering the conference room and sitting down, Ji Jie first asked a few questions about the company's business, then gradually steered the conversation towards elevator operation procedures. Dong Yinglu smiled apologetically after hearing the questions: "I'm sorry, although I'm a programmer, I'm not familiar with elevator operation procedures at all, so I'm afraid I can't be of any help."

Zhang Yang leaned back in his chair and replied unhurriedly, "Not familiar with it? Although you don't understand it now, you are a senior engineer. Learning some programming logic for elevator control systems shouldn't be difficult for you."

Zhang Yang called out in his mind. Shen Lan's voice immediately rang out—only he could hear it.

[Analyzing...]

[Dong Yinglu, legal representative of Beijing Tongzheng Company in Qianfeng Science and Technology Park, whose business registration information shows that the company's main business is customized development of enterprise-level databases, has a software engineering background and has participated in multiple industrial automation projects. Based on publicly available papers and project reports, his technology stack mainly focuses on the application layer and database architecture; there is no record of involvement in low-level embedded systems and real-time operating systems. Cross-comparison is underway and will be completed soon. He has no patents or technical papers related to elevator control systems.]

[Additional point: Two of this person's university classmates work at OTIS's China branch, but there is no evidence that he himself has direct experience with elevator control systems. He frequently adjusts his glasses when nervous; he did so four times just now. When asked about elevator technology, he answered "unfamiliar" rather than "completely ignorant," leaving room for interpretation, but his eyes didn't dart away, and his body language suggested anxiety about not being able to help rather than defensiveness about being exposed.]

[Conclusion: He genuinely did not understand elevator operating procedures.]

Zhang Yang composed himself and didn't press Dong Yinglu further. He trusted Shen Lan's analysis; the man in front of him couldn't offer technical assistance, but that didn't mean the direction was wrong.

Ji Jie changed the subject, suddenly asking, "Is Liao Jiangqun interested in your major?"

Dong Yinglu paused, probably not expecting the question to veer towards his fiancée. He thought for a moment and said, "I wouldn't say I'm interested, but she..." He stopped halfway through, as if choosing his words carefully, "What exactly happened to A-Qun?"

Ji Jie didn't answer him, but followed up with, "But what?"

"She's very smart, has a sharp logical mind, and a certain talent for computer programming." Dong Yinglu said this with an undisguised admiration in his tone, but then added, "Sometimes when I'm stuck, a single sentence from her can make me see the light. If she were to really become a programmer..." He paused, shook his head, "I don't want her to work too hard. This line of work isn't suitable for women."

Ji Jie stood up and pushed the chair back to its original position: "Thank you."

Dong Yinglu also stood up and asked for the third time, "What exactly happened to A-Qun?"

Ji Jie wore a businesslike smile: "She's fine, she's doing well."

"Let's go." The last two words were said to Zhang Yang and Tian Rui.

As they exited the company gate and descended the steps, Zhang Yang spoke first: "He really doesn't understand elevator operation procedures. The questions I just asked were all about the basic logic of embedded systems. If he had any experience with them, he wouldn't have failed at any of them."

Tian Rui walked beside her, her tone very certain: "That must have been Liao Jiangqun's doing. The car belonged to Dong Yinglu, and she borrowed it to drive; the technology belonged to Dong Yinglu, and she learned it and used it. A cashier with meticulous logical thinking and a talent for programming, isn't that tantamount to admitting it herself?"

Ji Jie opened the car door, glanced back at her, and asked, "Where's the evidence?"

Tian Rui was momentarily speechless, but after thinking for a moment, she said, "As long as we can prove that she had the opportunity to commit the crime, we can detain her for questioning."

As soon as they finished speaking, they heard hurried footsteps behind them. The three of them turned around and saw Dong Yinglu chasing after them from the company gate. She ran to the car in a few steps, looking flustered, as if she had been fighting an unfinished battle in her mind before coming out.

"Officer Ji," he took a breath, as if he had made up his mind, "I just made that up. Actually, Ah Qun knows nothing about computer programming. She's quite slow and naive."

Ji Jie, with one hand on the car door, didn't rush to get in. She just stood there looking at him, her lips twitching slightly: "Think carefully first, is it the lie you were telling earlier, or the lie you're telling now?"

Dong Yinglu's Adam's apple bobbed. After a few seconds of silence, she said something unrelated to the case but related to everything: "Officer Ji, A-Qun loves me very much, and I love her too. We're getting married."

Ji Jie nodded: "I know, the wedding is on the 18th."

Dong Yinglu looked up at her, a deeper meaning in her eyes: "Does she know you came to see me?"

"I don't know." Ji Jie started the car and leaned half her head out of the window. "But we should thank you. Goodbye."

With a tap of the accelerator, the car turned out of the park gate, and in the rearview mirror, Dong Yinglu was still standing in the same spot, getting smaller and smaller.

In the car, Tian Rui held up the dress in her hand and said, "Ji Jie, is this a new dress?"

Ji Jie said with a smile, "You can borrow it for now, but you'll have to run errands for me again later."

"what?"

Back in the group, I saw Lao Zheng chatting with Ding Jian and Chang Baole.

Ji Jie rushed over and said, "Ding Jian, Bao Le, come with me quickly."

Old Zheng stopped him, saying, "Hey, hey, where are you going?"

Ji Jie whispered, "Just borrow it for half an hour, please don't tell Yang Zhen."

After getting on the bus, Zhang Yang looked at the three unfortunate men and said, "Well, now we've all been caught."

Arriving at a building next to Tong Jiaxian's apartment complex, the layout, the hallway, and the stairs were identical. The task was to run from the 25th floor to the 13th floor, push someone down, and then run back up, all within three and a half minutes.

Ji Jie timed it. Ding Jian was the first to return, panting as he sat on the ground. Ji Jie said disappointedly, "Oh dear, four minutes."

"Impossible," Ding Jian said after learning the whole story. "Absolutely impossible."

Tian Rui was panting as she ran, still wearing the dress Ji Jie had given her; the dress was already torn from running.

At this moment, Chang Baole also ran back. Ding Jian said, "This is absolutely impossible! The three of us men are so fast we can't even do anything in three and a half minutes. Can she fly?"

At this moment, Zhang Yang also ran back. Chang Baole's time was 4 minutes and 7 seconds, and Zhang Yang's time was 4 minutes and 8 seconds.

Tian Rui ran back, panting, and said, "Sister Ji, please...please compensate me for my dress. I can't climb the stairs in this dress at all, I really can't run."

Chang Baole laughed and said, "Oh, a glimpse of spring has just occurred."

"Fuck you."

Ji Jie said, "I have a feeling there must be another dress that looks exactly the same."

Tian Rui said, "Exactly the same?"

Zhang Yang thought for a moment and said, "Sister Ji, do you think she would keep the clothes she wore that day when she committed the crime?"

Ji Jie nodded.
