Li Yulan exclaimed in surprise, "So this Qi Changrui is a mixed black and white person? And it turns out that he is actually the subordinate of the foreign force we are looking for?"

  Du Ming nodded and said, "Yes, according to these materials, what we are looking for should be this Qi Changrui."

  Li Yulan said, "I really didn't think of that, what does Mr. Du need me to do?"

  Du Ming shook his head and said, "The information is not enough yet, and it's still unclear what kind of person Qi Changrui is behind the scenes. I need to investigate him for a while longer, so you don't need to do anything for now."

  "Alright, Mr. Du, I'll be ready at any moment," Li Yulan said seriously.

  Li Yulan then curiously asked, "Mr. Du, how did you obtain these materials?"

  Du Ming said, "Before I found you, I was caught by Old Zhu's office first. When he wasn't around, I rummaged through his office and found these files from the safe box. They were copied from a mobile hard drive, and there were also some paper documents in the safe box. Later, Old Zhu came back, and I restored everything to its original state. I think Old Zhu still doesn't know that someone has rummaged through his office."

  Li Yulan exclaimed, "No wonder you're Mr. Du! I couldn't find these documents at all, but you found them in no time. Unfortunately, we didn't have enough time, and we can't make a detailed copy of that paper document to take away."

  Du Ming raised an eyebrow and said, "Who says there's not enough time? I've already brought back the contents of the paper documents. It's not necessary to bring those papers back."

  Li Yulan exclaimed in surprise, "Already brought back? How did Mr. Du bring their contents back and where are they now?"

  Du Ming smiled and pointed at his own head, "It's here."

  Li Yulan was taken aback and said with some confusion, "Mr. Du means to remember it by heart? How is that possible?"

  "This can't be impossible," Du Ming said, pulling out a piece of paper from the side table and taking a pen to meticulously copy down the contents of the document he had seen at the underground gambling den.

  Li Yulan looked on in shock, her mouth agape. "Mr. Du, did you memorize this with your brain?"

  Du Ming nodded and quickly finished writing on a page, putting down his pen. "Actually, the rest doesn't make much sense, just some repeated transfer records. The key is this," he said, picking up his pen again and circling a bank account number on the paper. "This account, originating from overseas, I need you to keep an eye on it, observe its movements, if there's anything unusual, report back to me immediately."

  Li Yulan said, "Okay, no problem, just...". She seemed to still be immersed in the fact that Du Ming had memorized a stack of documents with his brain. "Mr. Du, you are simply a miracle."

  Du Ming smiled and waved his hand, saying, "This is the first time I've heard such a description. Now that you know how formidable I am, follow me closely and learn from me. You still have a lot to learn."

  Li Yulan nodded vigorously.

  Du Ming checked the files on that hard drive again and found a lot of information about Qi Changrui and his underworld gang.

  Du Ming copied the information from this part and put it on a separate U disk, planning to give it to Jin Ling'er next time they meet.

  Du Ming left Li Yulan's home and returned to the Yun family after discussing some task-related issues with Li Yulan.

  The next morning, Yun Cai found out that Du Ming had returned and asked with concern, "How is it? How did you handle yesterday's matter?"

  "My wife is now concerned about my work? Don't worry, the problem has been solved, although there were some twists and turns, but the task is almost completed."

  Yun Cai nodded and said, "That's good, can my personal bodyguard finally go to work today?"

  "Of course, of course, if it weren't for all these tasks and investigations, I would definitely be by Yun's side at all times."

  "Never mind, I rarely see you for several days at a time. Let's go, hurry up and drive, or I'll be late."

  Du Ming drove Cloud Rainbow to the company and himself went to the security room to play with his phone and take a nap.

  At noon break, Du Ming had just ordered a boxed lunch and was about to return to his room when he was suddenly stopped by Bai Mei Gui, "Du Ming?"

  Du Ming turned around and saw that it was Bai Mei Gui. He asked, "Bai Mei Gui? What's wrong? Are you looking for me?"

  "Uh, I have a bit of a favor to ask, could you help me out?"

  Du Ming raised an eyebrow and asked, "What's going on?"

  "Here's the thing, I have a cousin named Bai Yihuo who is currently attending university in Donghai City. She's a freshman and winter break is approaching soon. My uncle is very busy and doesn't have time to take care of her, so he asked her to stay at my place first. I originally agreed to pick her up today and help her get familiar with the environment, but something unexpected came up at work and I won't be able to leave until tonight. Can you please help me out and bring her back to my place for a night?"

  "This is a small matter," Du Ming said with a smile. "It's easy, isn't it just picking up a little girl and taking her to your home?"

  "Yes, but," Bai Mei said with some embarrassment, "my cousin has been a bit rebellious lately and might not listen very well, so please be patient with her."

  "Alright, a little girl, what can I do to her?" Du Ming said helplessly, "Isn't it just puberty? This kind of thing is normal."

  Du Ming readily agreed and that night went to pick up Bai Yihuo at Donghai University, as told by Bai Meigui.

  Du Ming first sent Yun Cai back home and then drove to Donghai University, which was mentioned by Bai Mei. He stopped the car at the university gate and got out of the car.

  Bai Mei gave Du Ming a photo of Bai Yihuo to look at, and Du Ming remembered her appearance in his heart. When he arrived at the main gate of Donghai University, he looked around but didn't see Bai Yihuo.

  "This little girl, hasn't arrived yet? Did I arrive too early?" Du Ming glanced at the time and found that he had also arrived two minutes earlier. After waiting for a while without seeing anyone, he saw a group of young people dressed up in flashy clothes swarming into a nearby bar.

  Du Ming stared at it for a moment and found that one of the girls inside was Bai Yihuo.

  "Hmph, I'm waiting for you here, but you've gone to the bar to have fun," Du Ming said to himself, "This little girl is really a careless child."
