"Zhang Yi, haven't you gotten up at this time?"

Feeling as if someone kicked the door open, and vaguely heard someone calling his name, Zhang Yi woke up, turned over, and rubbed his eyes.

Looking around in amazement, the narrow dormitory of only more than ten square meters, against the right wall of the dormitory are placed two iron shelves of high and low beds, opposite the bed are four wooden tables painted with red paint, and there are four small stools, and the ceiling fan above the head is creaking and turning.

He was lying on the low bed in the innermost part of the dormitory, the only window next to him, and the sunlight was shining through the glass, shaking Zhang Yi's eyes a little bit.

Seeing this scene, Zhang Yi sat up violently, wasn't he busy in the laboratory with the test of tackling key projects?

Shaking his head a little dizzy, Zhang Yi was a little confused, no matter how he looked here, it looked like the dormitory when he was in college.

Zhang Yi studied at Jiangcheng University, majoring in mining engineering.

At the end of the last century, the accommodation conditions of college students could not be compared with those later, and it was impossible to have air conditioning and hot water equipment, and this dilapidated dormitory only appeared in the college stage of life.

Looking at the familiar and unfamiliar figure in front of him, Zhang Yi's mouth opened for a long time, and he asked stupidly, "Are you ...... Andy?"

Li Guohua was stunned for a moment, "Do you kid have a fever?"

The more Li Guohua thought about it, the more he felt that there was such a possibility, this kid didn't go to class in the morning, he finished the morning class, and when he came back after washing clothes, Zhang Yi was still lying on the bed and falling asleep.

This is not like this kid's style, this kid doesn't skip class much, and he is usually jokingly called a model college student, and there are too few top students like him in college who don't skip class.

Li Guohua threw the freshly washed basin in his hand on the table next to him, walked quickly to Zhang Yi's bed, fixed it on the door of Zhang Yi's head with the back of his hand, and muttered: "It's not burning, could it be that it has become mentally retard......ed?"

"Fuck you!" Seeing Li Guohua's distressed look, Zhang Yi slapped away Li Guohua's hand on his head, and pretended to smile calmly, "You're mentally retarded!"

Although Zhang Yi has not changed much on the surface, at this time he has already set off a monstrous wave in his heart.

From the dormitory scene that appeared now, as well as the sudden appearance of the old friend in front of him who had disappeared in his world for many years, Zhang Yi had to think of a possibility.

That is, I crossed it myself!

He remembers very well that after graduating from university, Li Guohua went to work in remote mountainous areas, and later turned to administrative work, and in a chat with an old classmate, he also knew that Li Guohua seemed to be in the officialdom, and became the director of the county party committee office in his 30s.

After completing his master's degree at Jiang University, he went to the University of Queensland in Australia to study for a doctorate, and later studied for a postdoctoral degree, and stayed at the University of Queensland as a teaching assistant after the postdoctoral fellow left the station, until recently he returned to China and settled down in the Institute of Mining and Metallurgy of the Chinese Academy of Sciences in Jiangcheng.

Therefore, he and Li Guohua have not seen each other for 18 years.

What makes Zhang Yi most sure is that he and Li Guohua look and dress exactly the same as they did in college, even if these scenes can be reproduced, how can people still be the same.

Unexpectedly, I actually went back to college, but I don't know how old it is now?

Zhang Yi, who came back to his senses, asked Li Guohua, "Andy, what time is it today?"

At that time, there was no mobile phone, unlike now if you want to see the date and time, you can click on the mobile phone directly, at that time, you have to look at the date by the calendar hanging on the wall, and the time is mainly based on the watch.

He was embarrassed to ask what year and month it was, otherwise he would really be regarded as mentally retarded, but judging from Li Guohua's current clothes, indoor temperature and the scenery of the trees outside the window, it happened to be May or June in Jiangcheng.

"On the 7th, you can sleep, I don't even remember what day it is. Li Guohua looked at Zhang Yi and was fine, so he took the basin to the corridor to dry his clothes.

On the 7th, Zhang Yi silently recited in his heart, just now when he was observing the dormitory, he saw the principles of mining machinery, the introduction to mineral processing, and the study of mineral selectivity on the table.

These books are professional books, which are only used in the third year of college, and usually the roommates who don't use them often will put them in a drawer and stack them, leaving only the books for class on the desktop.

In other words, it's my junior year of undergrad, which is 1998!

Got off the bed and picked up the mineral selectivity study on the table, Zhang Yi gently flipped a few pages, looking at the words that were too familiar to be familiar anymore, Zhang Yi's eyes were a little moist.

It's a roommate's book, and he has a copy of this book too!

The book is a textbook issued by the school to students for use, but it is not the original version, but is copied from the original book and then bound.

The author of the book is the founder of the domestic mining industry, Professor Lu Guangji, who was elected as an academician of the National Academy of Engineering and an academician of the Academy of Sciences in 1995 when the country assessed academicians for the first time.

This book has had a great impact on Zhang Yi, not only because this book is regarded as a classic by the backward students in the mining industry and is a must-have book for everyone, but also because this book carries the career and dream he has pursued over the years.

Wherever he went, the book was with him.

From bachelor's degree, master's degree, to Queensland, Australia to study for a doctorate, Zhang Yi devoted himself to scientific research until he was 39 years old, because his father died of cancer, which made Zhang Yi realize that he owed too much to his parents.

When I was studying for a bachelor's degree and a master's degree in China, Zhang Yi went home to see my parents during the summer and winter vacations, although I met a few times in a hurry every time, but I was still able to reunite with the family.

Later, when I studied in Australia, although my parents were happy and felt that Zhang Yi had a great future, they had less time to meet.

As the saying goes, if your parents are there, you don't travel far!

Zhang Yi didn't understand the profound meaning of this ancient admonition when he was young, until he was almost unconfused, when his father died suddenly, and the pain of his son's desire for filial piety and the absence of his relatives hit him deeply, and at the same time he also had the idea of returning to China.

Although his father is gone, but his mother still needs to take care of him, his parents are his son, when he studied abroad, his parents depended on each other, and they also took care of each other, and he should return to China to fulfill his filial piety after his father was gone.

And because of the major breakthroughs he has made in scientific research, he has also published many papers with high impact factors in internationally renowned mining journals, making him well-known in the world's mining circles.

He is young and very powerful, and at the same time he is an international student from an internationally renowned university, so he has naturally attracted the attention of many domestic universities and scientific research institutions.

At an international mining conference, the Institute of Mining of the Chinese Academy of Sciences from Jiangcheng threw an olive branch to Zhang Yi, hoping that he would return to Jiangcheng to work, and promised him financial subsidies and a house at the same time.

Zhang Yi agreed after a little thought.

It's not because of how strong the research institute of the Chinese Academy of Sciences is, there are still many units with better conditions than it, but Zhang Yi returned to China mainly to settle down.

On the one hand, it is convenient to take care of his mother, on the other hand, Zhang Yi studied in Jiangcheng for his bachelor's degree and master's degree, and after staying here for seven years, he is still very familiar with Jiangcheng, so he decided to return to this familiar city.

It's a pity that it backfired, and Zhang Yi's development did not go smoothly after returning to China.

In terms of strength and level, Zhang Yi will continue to work hard, and after a few years, it will be easy to evaluate a professor-level senior engineer and mix with Changjiang Scholar and Chutian Scholar, but in fact it is not as simple as he thought.

The development of the institute is booming, but the resources are limited, and the allocation of scientific research projects has become a major problem.

As the saying goes, where there are people, there are rivers and lakes, and scientific research institutions are no exception.

Zhang Yi returned from studying abroad, and he was still a returnee, but the most important point is that Zhang Yi had no foundation in the research institute at all, and there was no scientific research project that fell on his head in the end.

This Zhang Yike quit, and reported the situation to the director many times, but the reply he got always waited, and then it was delayed again and again, and it was over.

In the end, Zhang Yi had no choice, so he found his mentor when he was a master's degree, and only with the help of his mentor did he receive a small project.

In fact, Zhang Yi didn't want to go to his master's tutor in his heart, speaking of which, Zhang Yi was the best among all the students trained by the tutor, and now that he was mixed up like this, Zhang Yi didn't have the face to go back.

But he also understood the gap between his ideals and reality, and in the end he was forced to choose a compromise!

After getting the project, Zhang Yi also worked hard, and he had to make some achievements.

Zhang Yi's subordinates were also unavailable, and there was no one to start, so he had to complete all the test tasks by himself, getting up early and greedy every day, doing experiments and writing materials day and night. In the end, I was so tired that my eyes were black, I fainted, and I was unconscious.

Unexpectedly, I woke up again and actually returned to my junior year.

......

Zhang Yi gently closed the book, and after the initial shock, his mood gradually calmed down.

Since God has given him a chance to start over, he must make up for the regrets of the previous life.

Father's illness is the root of the disease accumulated over the years of overwork, after more than ten years finally broke out, now back to more than ten years ago, father's body should still be very tough, as long as no longer overwork, pay attention to rest, and then check the body regularly, it should not be a big problem.

For the career, Zhang Yi will have enough of the feeling of being under the fence, this time he was reborn, and his head is not only the scientific and technological level that is 19 years ahead of the current industry, but also the development direction of the future society.

With this advantage, Zhang Yi wants to change his fate.

Controlling your own destiny is what Zhang Yi wants!
