You're dumping me, huh? Fine, then I'll just pick up the school beauty and make her my wif

Su Qinghe recalled, "Lin tide, Zhao Weilan, Shen Shiyu."

But after Su Qinghe finished speaking, she shook her head firmly: "Xixi and the others have no conflict of interest in this matter, so they have no reason to report us."

Xu Wenbin: "If that's not an internal leak, then someone must have been eavesdropping. Could it be that we didn't close the window properly that day, and someone outside heard us?"

"Take a good look around. We're at least ten meters away from the nearest window. Does that person have super hearing? How can they hear from that far away?" Song Mingxuan retorted.

"That's true..." Xu Wenbin scratched his head awkwardly.

Jiang Che stopped speculating: "Forget it, it's pointless to investigate who leaked it now. The key is how to deal with the upcoming investigation."

"I've already backed up all the data," Lu Ziang said. "I can provide whatever the school needs to check at any time."

"Old Song, please refine the project plan again, especially the part about the use of funds. Every single transaction must be documented."

Jiang Che looked at Xu Wenxiong, "Old Xu, go and contact those students who participated in the registration, and ask them if they are willing to cooperate with the school to verify the situation."

Xu Wenbin nodded and was about to open his phone to browse his contacts when Song Mingxuan's voice suddenly came from the side.

"Wait a moment."

Song Mingxuan flipped to the last few pages of his notebook, which contained his handwritten meeting minutes.

He pushed the notebook to the center of the table. "That budget of 500,000 was decided during our meeting here that night, right?"

Jiang Che nodded.

"I wrote a version on the whiteboard at the time, but I erased it later."

"But I sent the electronic version of the budget to our group chat of five people."

Song Mingxuan looked up at the group of people and said, "The group chat logs couldn't have been leaked, so there's only one other way: someone opened the file on their device, and that device was accessed by a third party."

There was a two-second silence in the living room.

Lu Ziang turned his laptop around, and on the screen were his background file access logs.

"I checked, the original budget document is stored in a shared cloud drive, and it has been downloaded three times since it was uploaded."

"The first time was by Song Mingxuan himself, the second time was when I imported it into the backend for testing, the third time..."

He swiped his finger across the screen, zooming in on the download history.

"The third time was Xu Wenbin's account, three days ago at 2:17 pm."

All eyes turned to Xu Wenbin.

Xu Wenbin was stunned for a moment, and the expression on his face changed from confusion to panic.

He stood up abruptly. "No... I did download it, but I did it to print it out and paste it into the project folder. As you all know, I printed out a paper copy of all the documents when I was preparing the defense materials."

"Where did you print it?" Jiang Che asked.

"It was at the print shop near the south gate of the school. That day, the printer downstairs in the dormitory was out of paper, so I went outside to print it."

Song Mingxuan: "So, you logged into your account on the public computer at the print shop?"

Xu Wenbin did not answer, but the fact that he stood still was the answer in itself.

Lu Ziang: "Let me check the login IP of your account three days ago."

Xu Wenbin's Adam's apple bobbed, and he took half a step back, leaning his back against the wall.

He wiped his face with his palm, from his forehead down to his chin.

"Old Jiang... if it really was me who logged into the printing shop and leaked the data, then this whistleblower letter is definitely related to me."

"It's my fault that you're in this situation."

Xu Wenbin beat his chest in frustration: "The reason you withdrew from the competition is because I foolishly logged into a stupid account at the print shop. It's all my fault."

"Don't jump to conclusions," Jiang Che comforted him.

"How can I not be anxious? It's my fault, it's my fault. You don't need to cover for me. I know the truth in my heart."

Jiang Che walked up to him and patted him on the shoulder. "Alright, have some water and sit down to rest. It's nothing serious, don't blame yourself."

Xu Wenbin sat back down in the chair, following the force of Jiang Che's hand.

"Old Xu," Jiang Che squatted down to look him in the eye, "Even if it really was leaked from the printing shop, it's not your fault. It was someone hiding in the shadows who did it on purpose. None of us could have predicted it."

"So what if you printed it on the dorm printer? If someone wants it, they can always find another way."

Xu Wenbin shook his head. "I understand the reasoning, but I feel guilty about you withdrawing from the competition, and I can't swallow this."

"Then use that energy on something worthwhile."

Jiang Che stood up again. "After Lao Lu finishes his investigation, if it's confirmed that the printing shop is the problem, you're responsible for going to that shop and getting the surveillance footage. I need to know who accessed your account."

Xu Wenbin looked up at him, his red-rimmed eyes gleaming as he nodded vigorously.

Lu Ziang's progress is very fast.

He pulled up all of Xu Wenbin's account login records for the past three days and arranged them on the screen by time.

"At 2:17, Xu Wenbin logged into the print shop and downloaded the budget spreadsheet. He logged out at 2:42."

Lu Ziang scrolled down, "But at 2:45, the same IP address logged in again, lasting for six minutes, during which it accessed three files in the shared cloud drive."

"Budget sheet, project proposal, and team division of labor sheet."

"2:45?" Xu Wenbin leaned closer to look at the screen, recalling in his mind, "I left at 2:40, I remember it very clearly, because I specifically checked the time on my phone at the time."

"That makes sense." Lu Ziang scrolled down the page. "After you left, someone logged into your account again using the same computer."

Did you not log out when you left?

Xu Wenbin opened his mouth, and the color drained from his face.

He didn't quit.

After he finished using the public computer at the print shop, he immediately closed the browser, but the cloud drive account and password were automatically saved by the browser.

The next person to use that computer can directly access his cloud drive simply by opening a browser.

"I..." Xu Wenbin's lips moved a few times, but he couldn't utter a complete sentence.

"Don't blame yourself." Lu Ziang's fingers continued to move across the keyboard. "More importantly, after this person downloaded the file from your cloud drive, the same file appeared in the outgoing mail history of an external email address at 8:11 p.m. that same night."

"What email address?" Jiang Che walked over.

Lu Ziang zoomed in on the screen; the domain name at the end of the email address belonged to a small marketing company.

"I've seen this domain name before when I was tracking smear posts on the forum."

Lu Ziang switched to another window and placed the two records side by side: "The IP address that posted the message and the registered address of this marketing company are in the same office building, and the legal representative of this company is named Wang Lihua."

It felt like the air in the living room had been sucked out.

Wang Lihua, Ye Yunjin's assistant.
