"Dad, what are you doing here?" Zhao Yuemin's own father put the drawings back in the drawer, looking puzzled.

"Yuemin, do you think the new drill bit can be conjured directly from the drawing?" Zhao Chunda explained, "The drill bit design and drawing are only preliminary. It also needs to be molded, steel body processing, powder loading, and pressureless sintering. With so many complex production processes, do you expect to be able to complete them at home? ”

Zhao Yuemin understands that, just as the newspaper said, practice is the only criterion for testing truth. It is still far from having drawings alone, and it is necessary to produce samples, then do tests, and repeatedly carry out statistical data before it is possible to come up with qualified products.

"Dad, what are your requirements for the production process, I will bring it to the factory and use the factory's production line to make samples for you."

"Joke...... Just our loose machine shop with a floor full of parts? Zhao Chunda shook his head and said, "At present, our Jiangbei Oilfield does not have this condition. Other relevant oilfield units also do not have this qualification. Except for a few mechanical technology research institutes in Beijing that have the capacity of this equipment, no other place is possible. ”

Zhao Chunda's words made Zhao Yuemin have almost no hope for the machine repair factory he will take over.

A few days later, Hu Lin came to the house.

Zhao Yuemin is worried about how to find a place to develop diamond drill bits. He entertained Hu Lin somewhat absentmindedly.

"Linlin, pour your own water."

"Linlin, take the fruit yourself."

If ordinary girls see that Zhao Yuemin is not in the right state, they may leave with interest. But Hu Lin, the first optimistic girl born in the oil field, is different. She generously poured water for herself, peeled apples for herself, and allocated an orange to Zhao Yuemin, and then moved a bench to sit at Zhao Yuemin's table.

"Brother Yuemin, what are you doing?"

"Brother Yuemin, what were you doing yesterday?"

"Brother Yuemin, what were you doing the day before yesterday?"

"What were you doing the day before yesterday?"

No matter how cold the atmosphere is, Hu Lin can always break the ice.

"Brother Yuemin, I'll show you something." Hu Lin smiled and took out a piece of paper from her bag.

"Letter of acceptance?" Zhao Yuemin was stunned for a moment, and suddenly saw the words "Beijing Petroleum Institute", and then Hu Lin's personal information.

In those days, except for the form, which was typed in advance, all other information on the admission letter was handwritten with a black pen.

Beijing Petroleum Institute, the predecessor of China University of Petroleum.

"That's good, Linlin." Zhao Yuemin became excited, took the admission letter, looked left and right, and felt extremely rare.

"Of course it's good. Beijing Petroleum Institute has the strongest petroleum professional faculty in China. Brother Yuemin, I said that if I wanted to take the petroleum major, I must be admitted. In the future, when I graduate, I will be assigned to return to Jiangbei Oilfield and work with you. Hu Lin's eyes flashed wide, and his face was determined.

"What if I don't do it next year?" Zhao Yuemin said with a smile.

"Really?" Hu Lin's eyes showed sadness.

Seeing Hu Lin's sad expression, Zhao Yuemin suddenly felt that he shouldn't make such a joke. He didn't know how to deal with Hu Lin's feelings.

"Don't worry, I will work in the Jiangbei Oilfield." Zhao Yuemin promised.

Hu Lin's face glowed again, and he pouted with pride and said, "My brother Yuemin is the best." The girls in the class know that you have become a section-level cadre. You're only a few years older than us, and you're already a factory manager. Brother Yuemin, we all think that you will definitely be the director of the bureau in the future. ”

"Director?" Zhao Yuemin smiled, "Linlin, when are you going to report." ”

"I'll leave at the end of the month." Hu Lin stood up excitedly and paced back and forth in the room, "I heard that the campus of Beijing Petroleum Institute is very large, and there is a large library, as well as a nationally renowned mechanical technology research institute. ”

"Oh?" Zhao Yuemin's eyes lit up, and he thought to himself, since the factory in his own oilfield could not make samples, it was better to go to Beijing with the drawings to see if there was a chance.

Zhao Yuemin told Hu Lin that in two weeks, he would go to Beijing to see her. Hu Lin clapped her hands excitedly when she heard this.

Zhao Yuemin knew that his father, Zhao Chunda, had extremely strong design skills, but he was not so interested in putting it into practice and walking off the production line from the drawings.

I'm afraid that drawing drawings is like fishing and playing cards for him, which is a hobby. And this drawing of a natural diamond drill bit is one of the many intricate designs in his drawer.

Zhao Yuemin asked for leave from the bureau and only said that he was going to see relatives in Beijing. He is very cautious and does not want to give out information easily until he is completely sure that he will come up with the product.

However, asking Su Guoliang for leave led to an episode. Su Guoliang's daughter, Su Hong, was also admitted to Peking University. Su Guoliang asked Zhao Yuemin to bring him some Jiangbei pork shops and sesame sauce for Su Hong.

Going to Beijing to see Su Hong made Zhao Yuemin's heart flutter. The dancing in front of the dance room and the chic and free manner during the interview made him deeply impressed by this unusual girl. He felt a hazy and irrepressible force in his heart, dragging him towards Peking University.

At that time, the railway capacity was not abundant, and the sleeper tickets to Beijing were not so easy to buy. Zhao Yuemin got a ticket for the lower bunk through the connections in the Jiangbei Oilfield Bureau.

The driver of the bureau drove Zhao Yuemin to the Huaiyang City Railway Station. The waiting room faces north, and there are two dark green doors in the middle facing the station road, for passengers to enter and exit and wait for the train. On the south side opposite the gate is the entrance to the passenger ticket gate, which has a gate of the same size and color. In the waiting room, there are wooden lattice benches lined up along the wall and in the middle for passengers to rest and wait, and there are two small ticket windows in the southwest corner.

If you enter from the south gate of the waiting room, you will find the long platform No. 1. Platform 1 is mostly covered with cement and half is dirt road, leading to the west crossing.

Zhao Yuemin carried a large bag and got into the car, and the carriage was already stuffed with people like canned sardines. At this time, there were still some passengers who did not get on the train, and the conductor shouted loudly below: "The passengers in the carriage, squeeze in again, so that the people below can get on the train." The people in the carriage moved as a whole, pouring out the air inch by inch, and the people who came up behind moved in one after another, sticking in, and stepping on their feet and hitting their shoulders have become actions ignored by the crowd.

In such a noisy environment, those who can buy sleeper tickets are naturally the envy of everyone on the bus.

Zhao Yuemin sat down next to the sleeper under the envious gaze of everyone and put the luggage away.

The train starts slowly.

On the train, there was nothing to do. Zhao Yuemin lay on the bottom bunk, in a daze. Suddenly, he heard a slight ** sound, and the face of an elderly passenger standing next to him turned extremely pale......
