Gu Xichi’s computer was specially meant for the laboratory and had documents with a private watermark that could not be copied and was difficult to remove.

After a while, his former mentor would pester him for his thesis and encourage his students. He was used to it and would look for a document to send out.

That was his standard.

As it was too rushed this time, he sent the report immediately to Qin Ran once he got it.

Gu Xichi reluctantly picked up his phone and opened WeChat. He clicked on Qin Ran’s chat and opened the document—

The striking watermark could be seen.

Gu Xichi put down his instant noodles indifferently, closed the document, and sent Qin Ran a pitiful emoji.

After that, he sent a begging emoji.

At the school doctor’s office.

Qin Ran was relaxing on the sofa and answering Lu Zhaoying’s question. “It’s a test report from my friend’s grandma that my friend sent me.”

Lu Zhaoying nodded and finally looked up from the document. “I know. Is the surname of your friend Gu?”

“Yes.” Qin Ran acknowledged. She pulled the blanket on her body and suddenly looked up.

“It’s Gu Xichi.” Lu Zhaoying placed the printed report next to Cheng Juan’s computer and looked at Qin Ran indifferently.

Qin Ran was speechless.

Her phone vibrated. She looked down and saw the two emojis that Gu Xichi sent her.

Cheng Mu watched as Qin Ling flipped through the pages. He wanted to ask him if he actually knew what he was doing.

Upon hearing Lu Zhaoying say the name “Gu Xichi,” he almost fell off his stool.

The usual detectives could barely get information on him. Cheng Mu also heard a little about it from Jiang Dongye and knew that Gu Xichi had a few subordinates, including Matthew and people from the slums.

Cheng Juan came back to reality and picked up the printed document.

His gaze moved from the computer screen to Qin Ran’s body. “How do you know Gu Xichi?”

His eyebrows were slightly knitted. He knew more than Cheng Mu and the rest. Gu Xichi meddled with those who walked on the edge of the law and was involved in all sorts of illegal activity. How could Qin Ran have anything to do with him?

In fact..

Cheng Juan looked at the detailed report. Gu Xichi’s watermark was very obvious and did not seem to hide anything.

Gu Xichi was a strange person and he would not entertain normal people.

The most common thing he did was to go the slums or war-torn areas to treat the sick.

The laboratory report was casually sent—he wouldn’t send it to someone he didn’t really trust.

Naturally, Cheng Juan thought about the news of Gu Xichi in Ninghai Town. This time, he suddenly appeared in Yun Cheng and got into a fight with Jiang Dongye because of Chen Shulan.

What was the relationship between the two? Why would Gu Xichi put in so much effort for her?

Cheng Juan glanced at the document and did not say anything. Instead, he stood up from the sofa, went to his temporary laboratory, took out a few test tubes, and turned on the microscope.

After half an hour, a report was printed out.

Cheng Juan took out his phone and casually took a photo.

After that, he sent it to Qin Ran. “All you have to do is send this to him.”

Qin Ran slowly lowered her head and sent the photo to Gu Xichi.

Gu Xichi quickly replied to her with a thumbs-up emoji.

Qin Ran did not want to reply to him at all.

Not even a punctuation mark.

Li Dazhuang lived up to his name.

“It’s not 10 pm yet.” Cheng Juan lowered his head and looked at the time on his watch. After that, he glanced at Qin Ran. “Shall we go out for a chat?”

Qin Ling immediately turned to look at Qin Ran.

He closed his English book.

Qin Ran kept her phone and gave Qin Ling a pinky promise. “Xiao Ling, let me send you back first.”

Qin Ling took the English book, stood up, and followed behind Qin Ran.

Cheng Juan took his car key. After that, he took his jacket and gave Qin Ran her jacket. “Let’s go.”

**

The atmosphere between Cheng Juan and Qin Ran was a little strange as the three of them walked out.

After that, Cheng Mu finally spoke to Lu Zhaoying in a low voice. “Young Master Lu, do you remember that during Miss Qin’s apprenticeship banquet, there was a friend with the surname Gu that did not show up. Was it Gu Xichi?”

At this time, the things they missed flooded their minds.

Why would her friend with the surname Gu tell Grandma Chen that he was coming, but after Qin Ran left for a while, he never arrived?

There was also the pink object she said was glass, but Cheng Mu did not dare to verify it. It was obviously an uncut pink diamond, right?!

Gu Xichi was very familiar with the diamond trade and he probably had enough uncut diamonds to play marbles with, right?!

Just now, Miss Qin also gave Cheng Juan three million..

At first, Cheng Mu thought it was an illusion, but this time, it made sense.

He thought about the type of people Gu Xichi knew. Diamond mafia bosses, police officers, and gangsters. How would a simple person be related to Gu Xichi?

Lu Zhaoying touched his earring. Didn’t he remember? He was about to go crazy, but he still asked himself if he remembered. Of course, he did!

He even joked with Qin Ran and said that her friend had the same surname as Gu Xichi.

At that time, what was Qin Ran’s reaction?

She just looked at him!

“It turns out that we were so close to catching Gu Xichi before?” Cheng Mu looked at his phone.

He actually did not dare to tell Jiang Dongye about this news..

If he knew, he would probably cry.

On the other hand, Qin Ran called Qin Hanqiu. She knew that he was still at the barbecue stall.

She sent Qin Ling there.

Qin Hanqiu was still drinking with Qin Hanqiu and lamenting for the past two hours.

When Qin Ran went over, his face and eyes were red.

“Ran Ran, I’ll just pick him up with Old Zhou..” Qin Hanqiu stood up and took a piece of tissue paper to wipe his nose. He gestured for Qin Ling to come over. “This.. this is..”

Before he could finish, he saw Cheng Juan standing behind Qin Ran.

Cheng Juan was wearing a black coat. He had a long figure. Under the subtle reflection of street lights, his droopy face appeared exquisite.

He greeted Qin Hanqiu politely. “Hello, uncle.”

He also introduced himself.

“Oh.” Qin Hanqiu was suddenly excited. “Xiao Cheng, have you eaten? Eat some barbecue with me..”

“Dad, you should go home.” Looking at the time on her watch, Qin Ran said, “It’s 10 pm. Qin Ling should be asleep.”

Qin Hanqiu was a little terrified of Qin Ran. He nodded and reluctantly said, “That’s true. It’s time for him to sleep.”

The hotel was diagonally opposite them, so the three of them turned around and went over.

Cheng Juan sent the three of them to the hotel lobby very kindly. He even looked regretfully at Qin Hanqiu because he did not manage to eat some barbecue with him.

The back view of the three people disappeared. After that, Cheng Juan looked at his surroundings and saw a bar nearby.

Five minutes later, the two of them sat in a corner of the bar.

There were few people there.

Leaning against the chair, Cheng Juan habitually took out a cigarette. However, he did not light it and only looked at Qin Ran. “Did Gu Xichi appear in Ninghai Town because of you as well?”

“Yes. I let him visit my grandma.” At this time, Qin Ran did not deny it. She took the glass that was placed at the side.

Cheng Juan did not like mixing in the Cheng family business.

Old Master Cheng told Jiang Dongye to investigate Gu Xichi, but Jiang Dongye couldn’t find any information for years.

That was because Gu Xichi suddenly had another hacker behind him that could change his accommodation information at any time.

When Jiang Dongye couldn’t find anything, he would look for Cheng Juan.

Cheng Juan gave Jiang Dongye the few traces he had.

Cheng Juan had a few encounters with the big boss.

He went straight to point, did not drag anything, and was very calm about it.

Thinking about it, his style of doing things was too familiar!

Gu Xichi’s last appearance was three months ago in Ninghai Town. The information about his arrival was also covered up.

Jiang Dongye begged Cheng Juan and Cheng Juan gave him an address.

He was quite curious about who was behind Gu Xichi. The person could wipe out all kinds of flight, hotel, and even purchase records.

After Cheng Juan was done with his task, he went to Ninghai Town with Jiang Dongye to see what was going on.

As expected, Jiang Dongye could not find anything.

After that, he went to Yun Cheng because of the file of the unsolved 712 case. Of course, he stayed in the school doctor’s office and Cheng Juan did not deny that he had selfish motives.

Later, all the technicians in the Qin Ran paid respect to Qin Ran.

Cheng Juan suspected that the 712 incident was related to her.

The last time when Qin Ran showed him a radiation report chart, he suspected that the report was related to Gu Xichi.

The disappearance of the photo in Jiang Dongye’s hands was too coincidental.

The arrogant style of the picture on his computer was also very familiar!

Cheng Mu caught up with Cheng Juan’s thinking on this point. Everything related to Gu Xichi was not simple.

Cheng Juan narrowed his eyes, looked at Qin Ran, and chuckled softly. Slowly, he said, “Are you the one who’s been messing around and making all sorts of outrageous changes regarding Gu Xichi’s information? Li Dazhuang?”

He was sure of it!
