Although Qin Hongfei has only been back to this era for a short time, she has been in the other world for more than 20 years. Her scientific research experience since she was a child is not in vain. To learn scientific research, she naturally needs to thoroughly explore the development of this industry.

She knows very well that even if the Internet was just developing in the 1990s, even if the computer teacher knows little, it is impossible for him to not understand the difficulty of making a new system.

Most likely, he has taken all the achievements of the young man in front of him for himself. Such shameless people are actually very common everywhere!

The scientific research report made by the students! Was noticed by the teacher, and then registered under his own name.

Jiang Wan said with a dull look on her face, "How is that possible? My teacher is a very nice person."

Qin Hongfei's guess was just one and she naturally wouldn't say it outright. It would be so embarrassing if she was wrong: "You can check the relevant reports and search for relevant information when you go back. I'm just making a rough guess. As for the new system, you don't have to question your own ability. The bugs in the new system are nothing more than those, incompatibility, viruses, and inability to boot into the main desktop. Just solve the boot problem first, and then think of a way to solve the compatibility problem." After a pause, she said, "Do you have a pen and paper?"

Jiang Wan shook her head consciously.

Qin Hongfei stood up and said, "Help me watch the stall, I'll go buy something."

After buying a pen and paper nearby, she began to write something on the pen and paper. After half an hour, she casually threw the notebook to Jiang Wan and said, "I have written down all the possible problems of the new system. You can eliminate them one by one according to the steps. I think... that's about it."

Jiang Wan was a little confused.

He opened the notebook and looked at it.

They were all things from the calculation course.

Are you so awesome?

But...

but the steps to solve the problem were written very simply. He couldn't help but wonder, can the problem really be solved so easily? "Little boy, you didn't write this just to trick me, did you?"

Qin Hongfei could understand his doubts and said slowly, "You don't have to worry about it, because there's nothing worth tricking me about in your current condition." He had no money and no looks. "Now, please move aside and don't block me from doing business."

Jiang Wan stood up awkwardly and moved aside, wanting to say something but stopping himself. However, a new customer had already arrived, and Qin Hongfei was greeting the new customer and ignored him. He had no choice but to leave hesitantly with the notebook in his hand.

The new customer came to ask for prices but didn't sell anything, so he left soon. Qin Hongfei turned around and found that Jiang Wan was gone. There was a calm thought in her clear eyes. She didn't know if this big brother would be able to use it. The things written in the notebook were just some common sense questions for her, but for Jiang Wan, they might be life-saving things.

Qin Hongfei was not blindly kind...

It's just that she was once brought out like this! Sometimes, a small action for yourself may save someone else's life. What's more, Jiang Wan may not believe it, and even if he believes it, he may not use it. If he uses it, it is his own luck. Qin Hongfei collected her thoughts and continued to do her business.

Just as Qin Hongfei said, she now looks too old to be able to write convincing novels, and others may not necessarily be convinced by what she writes. Jiang Wan didn't take it seriously after taking it back, and continued to fiddle with her system with the last glimmer of hope, but she still failed after a whole night. When she had a splitting headache, she glanced at the notebook and couldn't help but open it. After realizing her actions, she smiled bitterly.

"Jiang Wan, Jiang Wan, you are really desperate. The child is only a few years old. How can he know how to calculate such profound things..." "
