After Cheng Jin finished speaking, Cheng Jun didn't say anything, and still looked at the direction outside the door.

After a while, he turned to Cheng Jin and spoke indifferently: "Want to see me?"

The study room was very quiet and there was no sound outside the door. Cheng Jun's words were a bit sarcastic.

"Tomorrow, the group headquarters." Cheng Jin lowered his eyes.

Cheng Jun smiled. He glanced at Cheng Jin, his eyes were quite light. In the end, he didn't say anything, and just said casually: "I understand."

After saying that, he opened the door and walked towards Qin Ran.

Cheng Jin was still standing there, looking at Cheng Jun's back, and couldn't help but pursed his lips.

**

Cheng Mu's collection room.

Qin Ran is still studying some rusty locks.

This was left to her by Chen Shulan. She didn't want to break it with brute force, but Chen Shulan didn't leave her the key either.

Just when she wanted to find a lock unlocking expert, Cheng Jun squatted down beside her: "Do you want to unlock the lock?"

"Well," Qin Ran was still half-squatting in the same place and fiddled with it for a while. The lock was quite retro, and I don't know why there was so much rust. "I don't know if it can be opened."

Just as she was thinking, Cheng Jun reached out and pulled away the box from her hand, and looked at it, "The spring beads are stuck, and they can be opened."

He said, asking Cheng Mu to bring the toolbox over.

Then he took the wooden box outside, put it on the table, and pulled open a chair and sat down.

Qin Ran followed him and sat opposite him, with her hands loosely on her chin, looking at him curiously, "Can you open this?"

She felt that she had learned enough and messed up. What kind of mess did Cheng Jun learn about this?

Who can associate doctors with locksmiths?

It seems that I heard from Qin Hanqiu that he was doing well in economics.

"It's okay, I've studied it for a while." Cheng Jun glanced at her and spoke slowly.

Cheng Mu took out the toolbox, Cheng Jun reached out and flipped through it, found two paper clips, pinched his slender fingers slightly, straightened them easily, and then bent the end into a tiny arc.

He took out a wrench and inserted one end into the lock core.

Qin Ran had never studied the structure of these locks, and in her eyes, there was no lock that could not be beaten.

At this time, I didn't see how he operated it.

His eyes were just looking at Cheng Jun. He was always lazy in his daily work, and it seemed that most things could be predicted and he didn't take them seriously.

At this time, he lowered his eyes, his clear contoured side face was a little light, and he showed confidence.

"Crack--"

The lock is opened.

Cheng Jun threw the paper clip and wrench into the tool box, then raised his chin at Qin Ran, and tapped his fingertips on the blue box: "Take it."

Qin Ran was not very careful about Cheng Jun and Cheng Mu, so she opened the lid of the box.

There was a document inside, like a research report, and a piece of metal that looked like a dark black. I don’t know how many years it has been left without any rust.

Cheng Mu saw these but couldn't see anything.

When Chen Shulan and Ning Wei were in Yuncheng, Cheng Mu realized that the two of them didn't look like ordinary people, but he couldn't guess what was wrong.

Of course, he couldn't see it at this time. He just looked down at the wooden box and then withdrew his gaze.

Continue to go back to the room to read the pile of books Qin Ran gave him.

Qin Ran looked at the research documents and pursed her lips, knowing that it should be the last thing left by her grandfather.

She flipped through the back, took the documents and the metal over, and flipped over a slightly yellowed letter at the bottom of the box.

As soon as he took out the letter to read, Cheng Jun suddenly pressed Qin Ran's right hand.

Qin Ran looked up, looked at Cheng Jun, and raised her eyebrows.

"Take it back to the room to see." Cheng Jun didn't look at her, his eyes just stared at the metal in the box. After a while, he raised his head, "Your grandpa...is really..."

He didn't know what words to describe, but his dark eyes showed respect.

"Okay." Qin Ran didn't ask anything.

She covered the box with a "slap".

The two went upstairs together.

After Cheng Jun went out, Cheng Jin walked into Cheng Mu's collection room and looked at Cheng Mu who was sitting cross-legged on the ground reading comics. He calmed down his face and asked, "Have Ouyang Wei contacted you recently?"

"No," Cheng Mu looked up and looked at Cheng Jin in surprise, "You don't let me contact her."

He hasn't figured out why until now.

Cheng Jin said "yes" thoughtfully, "That's right, you did the right thing."

"Ah, by the way, brother, wait, I'll transfer some money to you." Cheng Mu remembered something, he took out his cell phone and transferred 20 million to Cheng Jin.

Cheng Mu has to go through many procedures to transfer money, not as fast as Cheng Jin, 20 million, and it will probably take several hours to verify it before the account can be received.

But Cheng Jin saw the 100 million yuan in Cheng Mu's account, and he paused for a moment and was quite surprised: "Where did you get so much money?"

"Miss Qin taught me." Cheng Mu raised his chin, and he could see that he was quite proud in his eyebrows.

Seeing Cheng Mu like this, Cheng Jin simply said nothing.

He stood up and went straight out of the room door.

"I'll go to the study to handle something." Back upstairs, Cheng Jun glanced at Qin Ran, reached out and touched her cheek, "Don't think too much, do whatever you want."

After thinking about it, he lowered his head, "It's better to follow me lately."

Qin Ran looked at him, Mr. Xu had said this to her before.

She nodded, originally wanted to ask Cheng Jun if he knew what was in the box.

But looking at Cheng Jun's reaction, she could probably guess, and he must have known.

She turned around and walked towards the room thoughtfully.

"Forget it," Cheng Jun looked at her back, thought for a while, and then reached out and pulled her back, "Go to the study together to study."

What Chen Shulan left behind is indeed Ning Er's research data.

Qin Ran sat on the desk in the study, looking at the information on it.

It is indeed as Mr. Xu said, another list.

Chen Shulan has always been Ning Er's assistant. Fang Zhenbo called Chen Shulan Professor Chen at Chen Shulan's funeral, and obviously recognized her.

Cheng Jun turned on the computer and pulled a video with Cheng Shui from Mzhou.

After the meeting, he went out to answer the phone.

Qin Ran sat on the chair, looked at Cheng Jun's back, and knocked on the list left by Chen Shulan with one hand, thinking for a moment.

Before I could figure out anything, the phone I kept at hand rang.
