"It's been over..." Xiang Xiaofei hurriedly stepped forward to comfort the excited brother, "It's been three days...what are you doing..."

"H-type fin economizer! Now I feel disgusting when I see the 'fin'! Tell my mom, I throw the fins away next time I stew the fish!" Zhang Yifu threw the damn design drawings to the ground.*

Zhao Hongqi also came over at this time and picked up the picture. He looked at it and was dizzy enough. For him, who had no idea what he could tell, this thing was even more terrifying than Tianshu. He just covered his head and asked, "Brother... there are no fish fins on it?"

"Everything said, don't mention the 'fin'!" Zhang Yifu took the design drawing and slapped Zhao Hongqi in the head, "This is intellectual property, don't look at it!"

Zhang Yifu has never paid so much attention to intellectual property in his life. He is almost exhausted even if he copycats. How difficult is the original development! He blamed himself for all the pirated copies he has used in his life!

"I can't it be fine if I don't read it..." Zhao Hongqi said with a sad face, "I guess not many people in the country can understand this thing."

"So you have to find someone who can understand it." Zhang Yifu finally calmed down and rushed to Xiaofei, "Xiaofei, please buy me a train ticket to Baozhou!"

"Baozhou? What are you doing in Baozhou?" Xiang Xiaofei only thought for a moment, then quickly realized, "Go back to school?"

"Well, I have to go back, and the real experts are there."

…………

One afternoon a day later, after half a year, Zhang Yifu returned to the Northern Electric Power Academy again. He felt that the air here was fresher and purer than other places.

Counselor Wang Ruisheng waited for people at the gate. He saw Zhang Yifu, who was dressed in a neat manner, but he didn't dare to recognize him at first. When he got closer, he still had the usual smile that Zhang Yifu had made him confirm that this was the person he was waiting for.

"Oh, Yifu! I haven't seen each other for more than half a year, so I'm matured very quickly!" Wang Ruisheng then laughed and came forward.

He didn't dare to admit it at first, but it wasn't really his fault. Zhang Yifu spent all four years in college and passed the exam. He was famous for sleeping. He belonged to the type of person with the lowest awareness and the most cynical one.

No one would have thought that Zhang Yifu was like this after just over half a year of entering society.

The more Wang Ruisheng looked at Zhang Yifu, the more relieved he felt. After shaking hands, he smiled and said, "No. I should call Section Chief Zhang. Come on..."

He said, taking out his business card.

Zhang Yifu had no choice. It was embarrassing to exchange business cards with people he knew, but since the counselor insisted on doing so, it didn't matter.

The two of them changed their business cards and sighed, and both felt that the world was changing so quickly.

Wang Ruisheng is no longer an ordinary counselor. He has been promoted to the secretary of the Youth League Committee of the college, which can be regarded as entering the career path of the education system. Zhang Yifu is even more exaggerated. The head of the technical department of Jibei Power Plant and a senior engineer. For the 23-year-old, these titles are too heavy.

Wang Ruisheng was not very surprised. He thought he had heard about Zhang Yifu's situation from his alumni. After sighing, he said "It's not simple", he enthusiastically led Zhang Yifu to the college.

"I have already said hello. Professor Chang from the Department of Power is guiding the master's students today. Let's just disturb you."

"Thank you, thank you. Professor Chang Siping is not easy to make an appointment, thanks to Teacher Wang." Zhang Yifu said gratefully.

"Hey! I can't be considered a teacher. I can just call him a teacher when I was in school. Now I'll call him Ruisheng, or Lao Wang, too, haha."

While chatting and laughing, the two entered the teaching building of the power department.

Strictly speaking, the power department is just abbreviation, and its full name should be the "Department of Energy Power and Mechanical Engineering". It belongs to the second largest department of the Northern Electrical Institute. After the college becomes a university in the future, the so-called "department" will also rise and become a college.

The largest current department is naturally the power department where Zhang Yifu is located. The courses and majors are wider, mainly electrical basics, power systems, motor science, power transmission and distribution, relay protection, automation, electromagnetic fields, etc., as well as some economic and management teaching, such as power planning. However, the power department is more specialized and aims to study actual industrial topics. Perhaps in industrial research in other fields, the power department is not outstanding, but only in industrial engineering used in the power industry. In terms of thermodynamics, steam turbines, boilers and auxiliary machines, the power department of the Northern Electric Institute can be ranked among the top three in the country.

The two of them went all the way to the third floor and found the laboratory, then knocked on the door and entered.

The laboratory is not big, but there are many equipment. In addition to the secretary's documents and other materials, there are also two computers, which can be regarded as luxurious configurations.

At this time, an old man was worried about the computer in the laboratory. The old man's hair was half white and energetic, while the young man was on the other hand. His hair was black and he looked a little weak with thick glasses.

The old man thought it was Professor Chang Siping. When he saw the two of them coming, he was not in a hurry to get up to greet him. He waved his hand slightly: "Wait for a moment, let's solve this problem."

"Sure, let's do your business first." Wang Ruisheng smiled helplessly when he saw this and whispered to Zhang Yifu, "When Professor Chang is busy, even if the principal comes, he has to wait for him to finish..."

"I understand, do you have academic knowledge? I'm not in a hurry."

So, Wang Ruisheng signaled Zhang Yifu to take it upon himself, and he found a chair and sat down, picked up a professional magazine and read it.

Zhang Yifu was quite interested in the study of the two. He quietly came to the computer and stood behind them.

There is an extremely simple geometric figure on the screen, about an irregular pentagon with a tangent line in the middle. Chang Siping pointed to the angle between the tangent line and the edge and said: "Here, how should I use it to mark the angle?"

The graduate student's expression was a little tired: "Teacher Chang... This software is really not easy to use. I have used it for so long to draw a pentagon, and I have to mark the angle..."

"Study it, study it." Chang Siping was unmoved at all, "It's only a little more difficult? I'm persisting with such poor English. What are you afraid of?"

"Oh..." The graduate student sighed helplessly, and began to drag the mouse around and typing it on the keyboard. After half a minute, he still couldn't find the operation command. He spread his hands and said, "How about you come, I'll go and draw pictures with paper. With the time we used on this software, many designs have come out."

Chang Siping looked disappointed: "You don't understand. This thing will sooner or later be eliminated from hand-made drawings. I force you to study this now, and it will be more convenient for you in the future. I am still learning at such an age, let alone you?"

"No... computers are too stupid..." The graduate student took off his glasses tiredly and rubbed his eyes. "Maybe there will be smarter software in the future, but I really don't think there is any need to study this."

At this time, Zhang Yifu's voice came from behind: "It is not convenient to operate versacad."

The two were stunned at the same time, and the graduate student asked subconsciously: "Have you used this software?"

"It's not just used it, but I'm so big that I'm too big to make a picture." Zhang Yifu scratched his head and smiled, "But there's no way. I don't have the basics of industrial drawing, so I can only use software."

When the graduate students heard that they had no foundation, most of the interest they had just developed disappeared in an instant.
