A professor's rebirth: I entered Tsinghua University in 1977.

When Liu Hongyi suddenly decided to leave the farm, the people he was most reluctant to part with were Xiao Yawen and Ai Xiaoyu.

Ai Xiaoyu was crying with tears in her eyes.

It was the kind of silent crying, without any sound, just tears flowing non-stop, looking so aggrieved that anyone who saw it would feel distressed.

"Ai Xiaoyu, don't cry. I'll be back soon. My home is here..."

Liu Hongyi hurried to comfort her.

Ai Xiaoyu just cried, but said: "I know, your work is revolutionary and cannot be delayed, I know..."

Although Xiao Yawen was reluctant to let her son leave, seeing Ai Xiaoyu like this, she came over, took her hand, patted her gently, and comforted her: "Xiaoyu, don't worry, Hongyi will be back soon. You can live here with peace of mind, this is your home. If you have any problems, tell your auntie, and she will definitely help you."

Ai Xiaoyu finally stopped crying after being consoled by everyone, but she didn't sleep well that night and was groggy in bed, which made Chen Aiping sleep poorly too. When she woke up the next morning, she saw two giant pandas.

Duan Weimin's side is very efficient. He contacted the person in charge of Chuzhou yesterday. When they heard it was a military project, they naturally didn't dare to interfere and agreed immediately.

Early in the morning, Yuan Gang and his companion drove a jeep to the cadre school to pick people up.

Both of them have packed their luggage.

It was pretty simple, just some spare clothes. Tan Dexi also brought an abacus, an English-Chinese dictionary, and some information.

Amidst the reluctant gazes of the crowd, the two boarded the jeep and waved goodbye.

Looking at the jeep disappearing into the distance, Ai Xiaoyu couldn't help herself and burst into tears in Xiao Yawen's arms.

Xiao Yawen comforted him again.

She had taken a liking to this girl, and if nothing unexpected happened, she would marry her and bring her home to be the daughter-in-law of the Liu family.

Chuzhou is two hundred kilometers away from Daning. The road conditions cannot be said to be bad, but only extremely bad!

The road was full of potholes, and the speed of the cars was slower than a snail, according to Liu Hongyi. But given the current conditions, there was no rush.

Fortunately, Liu Hongyi has a very mature mentality. He is steady and silent. It is nice to take a good look at this pristine and beautiful land.

Along the way, whenever we passed through a market town, the most obvious characteristic of the era was the large white and gray slogans that could be seen everywhere on the buildings.

Given the current road conditions, it would take at least six hours for a jeep to drive from Yanggou Cadre School to the provincial capital.

Including the time spent eating on the way, it took a full seven hours.

Moreover, the jeep had no air conditioning. It was summer and the car was very hot. Even when the window was opened, the wind blowing in from outside was hot.

Seeing that Tan Dexi's sparse white hair was already stained with a layer of dust, Liu Hongyi couldn't help laughing and said, "Teacher, we are really exhausted."

A rare smile appeared on Tan Dexi's lips.

Even though he was mad at everyone, pushing Yuan Gang and even Duan Weimin up against the wall, he was actually quite happy. After all, he could resume his most familiar and favorite work, artillery design.

We were sweating all the way, and at around three in the afternoon, the jeep finally drove into the provincial capital.

Arrived at the institute at 3:30.

Duan Weimin attached great importance to the arrival of his old classmates and arranged for the office director to wait there. As soon as Tan Dexi arrived, he immediately led them to Duan Weimin's office.

Liu Hongyi looked at the research institute with some curiosity.

Although he had experienced that era, he had not been to the Military Research Institute very often.

It was actually a very ordinary courtyard, with gray walls and gray tiles. Apart from the armed soldiers standing guard at the gate, it was no different from other units.

When we arrived at Duan Weimin's office, a leading cadre in his fifties, wearing an old light yellow military uniform, a red collar badge, and a red five-pointed star on his head, immediately stood up and came forward with a smile.

"Hahaha, old classmate, I've been waiting for you to come."

He looks at least ten years younger than Tan Dexi.

But Liu Hongyi knew that Tan Dexi's actual age was about the same as Duan Weimin's. One was pampered and aloof, while the other worked hard on the farm from dawn till dusk. Over time, that's how they naturally ended up.

"Hehe, Old Duan, if it weren't for this mission, you probably wouldn't even know where I am, right?"

"Ah, old classmate, you know, given the current situation... there's nothing we can do. We're all technical people, so we just need to do our technical work well."

You're not a technical person...

However, Tan Dexi did not say this sentence after all.

Some things can be said, but some words, once spoken, will really hurt feelings.

In fact, Tan Dexi still recognized Duan Weimin very much, otherwise he would never agree to come to the institute. Even if he wanted to contribute to the country, he would insist on returning to Factory 576 and would never let someone he looked down upon take advantage of this ready-made advantage.

It can be seen that although the old man is stubborn, he actually has a scale in his heart.

"Okay, stop talking nonsense and quickly arrange everything for us two. We'll start working tonight."

Duan Weimin smiled and said, "No matter how urgent the task is, it shouldn't be this serious. We still have to eat... By the way, this kid is your favorite student, right? He's quite young. Is he over sixteen?"

"Reporting to Director Duan, I'm almost sixteen."

"Ouch!"

"Old Tan, you've given me a difficult problem. Our institute has never had such a young technician before."

Duan Weimin said half jokingly and half seriously.

"What? You don't trust my judgment? That's okay. Let's take the test. I'll give you three questions. Call all the junior, no, intermediate technicians in your institute over here. Let's work together to solve the questions. Whoever can solve them will pass."

"But Old Duan, let me be frank. If my student wins, you'll have to treat him like a mid-level technician, not just a junior one."

"We have to be fair and reasonable in everything we do, right?"

"Hey, why take it so seriously? Don't I trust you? I was just kidding. If you say he's a junior technician, then he's a junior technician!"

Duan Weimin would not be fooled.

You set the questions and test your own students. Do you think I, a deputy military-level director of a research institute, am stupid?
