Yingtai, a small railway station in the northwest, is so small that it is not marked on the map, and can only be found on a special military map.

A green train whistles, puffing thick white smoke slowly into the station, every 15th of every month, there will be a train arriving at this small station of Yingtai, not an ordinary train, but a special freight train.

Su Yichen rubbed his numb feet, and stood up in the carriage with the high and heavy goods stacked beside him. Since this is a military train, there is no passenger carriage at all, and naturally there are no seats, so he and Professor Wan Changchun are crowded in this carriage full of goods all the way, the conditions on this road are not very good, the sealed carriage is stuffy, hot and uncomfortable, and the most important thing is that you can't even drink more water all the way, because there is no way to go to the toilet.

"It's finally here!" Wan Changchun looked at the small station that was about to stop through the narrow ventilation window, and a smile appeared on his face. Behind him, Su Yichen, who had already moved, was removing their luggage from the shelves full of goods.

"Teacher Wan, this is the winning table?" Following Wan Changchun's gaze looking out of the window, Su Yichen leaned over and looked.

"Yes!" Wan Changchun nodded, pointed out the window and said: "This place was called Yintai in ancient times, Qianlong of the Qing Dynasty in the twentieth year, that is, in 1755 AD, the size of the Huijiang and Zhuo rebellion, the Qing army sent troops to suppress it, at that time, the army was divided into two roads, the counselor minister Erongan, the right deputy general of Dingbian Salal, went out of the west road and the North Route Army in Bortala to conduct a division, this place was the logistics of the West Route Army to store grain. The army fights, the ancients pay the most attention to superstition, Erongan deliberately changed the place name of Yintai to win the platform, in order to take the horse to the meaning of success, since then here has been passed down to the name of the winning platform. ”

"You know a lot!" Su Yichen sighed, he didn't expect that as an expert in electronic engineering and a famous professor in the School of Science, Wan Changchun would even know such a long history allusion.

"Less sycophants." Wan Changchun said with a smile: "This is still when I was sent to the northwest squatting cowshed, an old professor of history who specializes in the Western Regions told me a small story. ”

"That's not easy, it's almost seven or eight years, by the way, Mr. Wan, ...... old professor now?"

Wan Changchun's face suddenly darkened, and he shook his head with a sigh. Seeing his expression, Su Yichen regretted a little that he had mentioned something that he shouldn't have mentioned, I'm afraid that this old professor is probably long gone. At this time, there was a bang, the train stopped steadily, the carriage door opened from the outside, and Su Yichen hurriedly picked up his luggage and beckoned Wan Changchun to get off.

Got off the train and stepped on the simple gray platform, Su Yichen couldn't help but look around, except for the small winning station and a row of simple warehouses behind the platform, there were patches of green grassland in the distance, the cattle and sheep of the local herdsmen were dotted among them like white clouds, and the far away was the endless mountain range, and the white of the thousand-year-old snow could be faintly seen at the highest point of the mountaintop, if Su Yichen guessed correctly, this should be the famous Kunlun Mountains.

Su Yichen is a Ph.D. student in the School of Science of Shimen University of Technology, and his supervisor is Professor Luo Shaohua, Dean of the School of Science, a well-known physicist and computer expert in China. As a proud disciple of Professor Luo, Su Yichen has made small achievements in physics, electromagnetism, computer science and mathematics, and is known as Professor Luo's successor.

At the end of the 70s, Professor Tzu Yungui of the National University of Defense Science and Technology presided over and set up the project plan of China's supercomputer, the goal of which was to develop China's 100 million supercomputer - the Galaxy supercomputer, and the project team that Su Yichen joined was part of this huge plan, and the project team was mainly responsible for the overall design and comprehensive testing of the supercomputer general integrated circuit. At the same time, as a well-known expert in electronic engineering, Professor Wan Changchun served as the deputy leader of the project team. The entire project team took four years and was completed only two months ago.

But before he could feel the joy of the final success of the Galaxy Giant Machine, the school suddenly received an order from his superiors that due to the requirements of the national space department and the military, the Northwest Space Base was in urgent need of experts proficient in computer and electronic engineering. As the core group of China's first supercomputer general integrated circuit development project, the School of Science of Shimen University of Technology has requested the university to dispatch a group of experts to support it.

Originally, according to the plan, Professor Luo Shaohua led the team directly, but unfortunately Professor Luo Shaohua was temporarily unable to move due to physical reasons, in order to ensure the urgency of technical support, Su Yichen took the initiative to propose that he take the first step instead of the teacher, so he and Professor Wan Changchun went first as the first batch of people to set off, and Professor Luo Shaohua waited for his body to recover before he led the team behind to leave.

"The two of you are experts from Shimen, right?" Just when Su Yichen looked at the surrounding scenery and sighed with emotion in the poem, "The sky is vast, the wilderness is vast, the wind blows the grass and sees the cattle and sheep", a rough voice pulled him back to reality.

When he turned around, he saw a PLA cadre wearing four pockets standing in front of Wan Changchun, his face as dark as a knife, and a pair of bright and sharp eyes looking them up and down.

The reason why the other party asked them directly, the answer was actually very simple, because the entire train, including all the staff in Yingtai, were all soldiers in uniforms or military uniforms, and only Su Yichen and Wan Changchun were wearing civilian clothes. In addition, Wan Changchun is 60 years old, with gray hair and glasses, and an obvious intellectual appearance, which is extremely conspicuous among these people.

"We are experts from Shimen, you are the comrade who came to pick us up, right?" Wan Changchun hurriedly replied, smiling and stretching out his hand to the other party.

But who would have thought that the PLA cadres on the opposite side were not as enthusiastic as they imagined, and they didn't even raise their hands, but instead stared at Wan Changchun, who was about to shake hands with him.

Feeling a little strange, Wan Changchun soon reacted, and quickly retracted his hand and took out the letter of introduction and his special documents from his pocket. Seeing Wan Changchun doing this, Su Yichen also hurriedly put down his luggage, and also took out the red paper representing his identity from his jacket pocket.

The other party took the letter of introduction and the certificate, opened it and looked at it very carefully, and even compared the photo on the document with the person standing in front of him. After confirming that it was correct, the PLA cadres handed back the letter of introduction and documents to Su Yichen and them with both hands, and then raised their hands and saluted: "Hu Zhijun, platoon commander of the second platoon of the third company of the 781 base guard battalion, welcomes the arrival of the expert comrades!" ”

After saluting, he put down his hand, and Platoon Commander Hu, who was still vigilant in the face of class enemies a moment ago, instantly smiled on his face, took the initiative to take Wan Changchun's right hand with both hands, shook it extremely enthusiastically, and said: "Expert Wan, Expert Su, I can finally look forward to you." I'm really sorry just now, our troops have iron discipline, and we neglected you, please don't care about it! ”

"It's okay, it's okay, Platoon Commander Hu should do this." Wan Changchun replied with a smile, and there was no blame in his demeanor. The space base, that is, the 781 base, is a state-level secret unit, and they were reminded before setting off that they must carry the special documents they hold with them to avoid misunderstandings.

"The head of the base asked me to pick you up, did you work hard along the way?" Platoon Commander Hu asked very enthusiastically.

"It's not hard to take the train, it's just that the time to come all the way is too delayed."

"Hehe, this is also a helpless thing, you know, our side is very remote, and the arrangement of military columns has fixed procedures. By the way, our car is over there, it's not early, we still have to hurry, if it's convenient for you, let's go? ”

Wan Changchun knew that there was still a long way to go, and there was a long way to go from Yingtai to the 781 base, and he had to walk a whole day. In order to arrive at the destination as soon as possible, Wan Changchun of course would not refuse Platoon Commander Hu's arrangement, and nodded briskly in agreement.

Su Yichen picked up his bag, bent down and was about to take his and Wan Changchun's luggage, but Platoon Leader Hu hurriedly stretched out his hand to stop him, saying that where there were guests who came, they had to carry their luggage by themselves. Then he turned around and shouted, "Amir, come on!" ”

As soon as the words fell, a young minority warrior hurriedly came over and helped lift the luggage neatly, and even the bag that Su Yichen was already carrying on his shoulder was snatched by him, making Su Yichen, who had empty hands, a little embarrassed.

"Thank you, Comrade Amir." Su Yichen said.

Who would have thought that as soon as he said this, several young soldiers, including Platoon Commander Hu, suddenly burst into laughter, and the soldier named "Amir" suddenly turned red on his face, and said to Su Yichen in somewhat stiff Chinese: "My name is Gudamai." After saying that, he hurried to the car.
