Liang Yuan stood with his hands on his knees and sat under an extremely lush tree by the lake, staring at the fog rising between his fingers, allowing memories that broke through the shackles of reason to churn in his mind.

If the water flows backwards,

The fallen leaves flew back to the branches,

How many lovers are there until they are old?

If the water reaches the flow,

Everything can be started from scratch.

How many tears will stop flowing.

How many fallen leaves are blown away by the wind,

How much youth doesn't look back,

How many dreams are going with the flow,

Travel eastward.

Why can't you see through and let go of your hand?

I thought there was still...

After breaking up with Chen Qian in my previous life, the song "If Water Flows Back" that I have heard countless times seemed to echo in Liang Yuan's ears.

Chen Qian's home is located in Qingyuan City, southeast of Shengjing. If it is sunny, standing on a skyscraper over 40 floors of Shengjing, holding a telescope, you can even clearly see the outline of Qingyuan City on the horizon.

"Professor Zhu has developed a new material. Xiaoyuan, can you go to Qingyuan to see it?"

Liang Haiping asked this, and Li Yuanling also asked this. Every time Liang Yuan subconsciously shook his head and found various excuses and reasons to turn it over.

Qingyuan Special Steel, located in Qingyuan City, is a very well-known special steel smelting enterprise in the Republic. More than half of the special steel for aerospace in the Republic are from Qingyuan Steel Plant. Although the smelting equipment of the Northeast Locomotive Factory is very advanced after the technical transformation, before the vehicle factory introduced large vacuum furnaces, all Zhu Liguo's new material formulas were conducted on Qingyuan Special Steel.

In order to maintain the consistency of data and development experience, after Zhu Liguo obtained a 10-ton vacuum furnace, the cooperation with Qingyuan Special Steel was not interrupted, and a considerable number of metal formula experiments were still carried out in special steels.

The distance between Qingyuan and Shengjing is very close. After Liang Yuan's last lifetime, the East-West Expressway that runs across Shengjing was completed, it only takes a 50-minute drive from Shengjing city center to Qingyuan city center. For large cities in the Republic, the itinerary between the two cities is about the same time as the time spent across districts in the city. The two cities can be regarded as one city.

What am I hiding? Or what am I escaping? Can these things that have not happened still be considered as memories? There should be no regrets with Jia Jia by his side. Some things may not even be born at the beginning.

I don’t know if I can see the vague outline of Qingyuan City on the horizon after the Shangri-La Hotel was repaired and standing on the top floor with a telescope? Countless thoughts were rolling in Liang Yuan’s mind.

Maybe this is called "Long Watson". Liang Yuan smiled mockingly and turned his head to look at the big tree he was relying on.

It seems like the national destiny of the Republic after the two battles in Nansha. Some things are destined to not return to the past once they have changed. The big stump that Chen Qian liked when she was reading in the early years in her previous life is still growing lushly. There is no sign of becoming a stump.

Life is unsatisfactory. No one can get everything. Liang Yuan took a deep breath of cigarette, extinguished the dark red cigarette butts on the wet grass under him, stood up and patted the bark of the big tree with vicissitudes of life. Liang Yuan said softly: "Grow up well."

When Liang Yuan returned to the classroom, all the relevant experiments on liquid helium have been completed. Zhao Yinong is citing Landau's "quantum theory of helium 2 superfluidity" to briefly explain the causes of liquid helium superfluidity.

Back at the seat, Liang Yuan took out a piece of bubble gum from his schoolbag, threw it into his mouth and chewed it for a while, and then poked Wang Mengmeng. After confirming that there was no smell of cigarettes, Liang Yuan began to take notes with peace of mind.

"Students, today we have learned about magical superconducting materials and many unique phenomena in low-temperature physics. It can be said that the discovery of high-temperature superconducting materials has attracted the attention of countless top scientists around the world. If a normal temperature superconductor can be discovered in the future, human society and civilization will undergo earth-shaking changes."

Zhao Yinong raised his hand to look at his watch, and made a final summary while cleaning up the lesson plan.

"Nuclear fusion, which is almost endless energy, space engines that can be used for interstellar navigation, and new types of ground transportation systems are closely related to superconductors. It can even be said that the discovery of high-performance high-temperature or room-temperature superconductors will determine whether the future of mankind will stop at planetary civilizations or evolve into intergalactic civilizations."

"Students who are interested in this knowledge can come to the hospital office at any time. However, the difficulty of finding high-temperature superconducting materials is much higher than the difficulty of finding filaments when Edison invented the electric lamp. In order to find suitable filaments, Edison has tested tens of thousands of materials in order to find suitable filaments. Since humans discovered the superconducting phenomenon in 1911, it has been nearly a century in order to find suitable superconducting materials science. As of now, scientists from all over the world have tested millions of materials."

"In the foreseeable future, this kind of situation of looking for a needle in a haystack will continue. In the future, students who are interested in this research must truly love this major to achieve it. Real scientific research can be said to be a very boring job."

At the end of the course, Zhao Yinong emphasized the difficulties of low-temperature physics research, so as not to impulse the students in the junior class to choose majors that they are not really passionate about.

As the bell rang, seven or eight students who were interested in what Zhao Yinong had just said gathered around the podium and asked, and the others were packing their schoolbags to leave after school.

"Xiaoyuan, Mengmeng, are you both not interested in low-temperature physics?"

"Yes, Star Sailing sounds very sci-fi, very high-end."

Yu Wenjie and Song Fei quickly packed their stationery and carried their schoolbags, and ran to Liang Yuan and Wang Mengmeng's desks.

"You two, please ask Mengmeng. A guy like me who is on the verge of being fired will not have the heart to consider the problem a year later." Liang Yuan hid his hands in the desk, carefully re-fixing the hard-earned box of "food and grass", while saying with a bitter face.

Before the juvenile class officially chooses a major, it will conduct three years of preparatory education. During these three years, while everyone consolidates high school courses and learns some university courses, they must receive a more comprehensive science and engineering education. From physics to chemistry, from mathematics to biology, students can choose their favorite majors from several subjects and directly transfer to undergraduate and master's degree program in three years.

"I'm not interested in low temperature physics." Wang Mengmeng said simply.

"I heard from my dad that the new generation of chips in Nanhu Science and Technology Park has been invested in research and development. If nothing unexpected happens, the new chip will be successfully discharged at this time next year. At that time, the medical imaging system developed by my dad and others can break through the bottleneck of data processing. I think I may be forced into their business by my dad and my mom in the future." Wang Mengmeng said with great uncertainty.

Wang Mengmeng's parents Wang Yan and Ji Xiaomeng both engaged in the development of embedded processors at Dongda University. Long before Liang Yuan founded Yuanjia, the two had already started the research and development of medical ct control systems and image processing systems. Even without Liang Yuan's intervention, Dongda Digital Medical Equipment Co., Ltd., a university enterprise under Dongda University in history, was also the only large enterprise in the Republic that can produce medical and industrial cts. However, the Republic itself did not have any industrial processors to be put into use at that time, and Neusoft's core technology could only be based on Japanese hardware.

In the mid-1990s, although Neusoft's self-developed multi-layer spiral scanning CT was the first to break the sky-high monopoly of medical testing equipment abroad, due to Neusoft's high-level strategic vision and the Republic's relatively rigid economic policy towards the Northeast heavy industrial base, after entering the new century, Neusoft lost in the talent battle with emerging companies such as Huawei and ZTE, and eventually became a single person, and ultimately failed to grow into an international giant in the medical industry.

When Liang Yuan graduated in his previous life, all the technical backbone who was independently responsible for development projects at Neusoft, except for a very small number of them, almost all the rest were poached by Huawei, ZTE and other companies with high salaries. Neusoft was nicknamed the national technical supervisor reserve team by people in the IT industry.

Neusoft's first pot of gold came from software outsourcing by Japanese companies in the early 1990s. At this time, Liang Yuan had already put Dongda on a historical fork, so where could he wait for Japanese companies to integrate Dongda's computer talents?

Although Liang Yuan has not yet made a large-scale tossing work on the science and technology park, the basic cooperation work began two years ago, from the initial simple optimization of the remote control-related circuits to the custom development of railway signal systems, from the outsourcing of some sub-projects of the Hong Kong-based electric collectors, to the discussions between the two parties to establish a joint venture, the cooperation between Yuanjia and Dongda University has been deepening.

"Fatty, Song Fei, what are your plans?" Wang Mengmeng asked.

"Antarctic is too cold, I don't want to continue my dad's work." Yu Wenjie subconsciously shrank his head.

Yu Wenjie's father is engaged in geophysics related work and stays in the polar region for several months every year with the Antarctic scientific expedition team of the Republic.

"I might go to the mathematics department, or study programming with Mengmeng, which is also good." Yu Wenjie said.

"I haven't thought about it yet. I plan to think about it slowly this year. I really can't think of it. I will invest coins when choosing a major next year and decide what to learn." Song Fei said uncontrollably.

Recently, it was not Liang Yuan’s dormitory duty. After Liang Yuan hid the "food and grass" and packed his schoolbag, the four of them left the classroom together.

Standing at the three-way intersection leading to the dormitory and the school gate, Liang Yuan stopped and said, "Mengmeng, fat man..., you guys go back. I won't go back to the dormitory today. My mother can come back at any time in the past few days. I have to keep an eye on what I promised you at home."

"Okay, let's go back first, and Xiaoyuan, don't forget to ask about magnetic levitation." Wang Mengmeng added.

Liang Yuan nodded, waved his hand and said goodbye to the three of them, and turned onto the path leading to the main entrance of the school. (To be continued...)
