holy sword system

()Chapter 28 class

Wearing a gray school uniform and carrying a huge schoolbag, Su Yan walked quickly towards the classroom. The current Su Yan and the previous Su Yan seemed to overlap, and he returned to the student days again.

The gray and black schoolbag looks very huge behind Su Yan. Su Yan's body is only 16 years old, and his frame is not very big. It is only more than 160 centimeters. Such a height is due to his age. The reason should be the 16-year food shortage.

Compared with the crowd walking around the courtyard, Su Yan's height is obviously shorter, just like a junior high school student entering the world of college students, Su Yan is a bit out of place here.The walking crowd obviously also saw this, and all looked at Su Yan with strange expressions.Fortunately, no one showed contempt or ridicule because of Su Yan's height.Among them, there is not only caution about Su Yan's identity and background, but also ignorance of the weak.

The students of Fengcheng Military Academy are a group of self-proclaimed geniuses. They have physiques that exceed ordinary people. In terms of measurements, they have data that exceeds the average number of times.Intelligence, agility, or strength.For such a statement, Su Yan has the most right to speak. The information that flashed in his mind told Su Yan that most of the people here have data exceeding [-] points in individual attributes.

An ordinary person has an intelligence of nearly [-] points. Such a thing is extremely rare in the ruins. The guy in the mining area only has an intelligence of [-] points, and Harry only has an intelligence of [-] points. People are not called geniuses for nothing.

Power: 21

Agility: 9

Intelligence: 13

A black youth over two meters in size walked in front of Su Yan, and clear data appeared in his mind. People who are gifted in strength usually have a very strong physique.

Power: 11

Agility: 9

Intelligence: 23

Another person flashed past Su Yan's eyes. His intelligence as high as 23 points indicated that this person was extremely intelligent. Su Yan looked at the other person with a hint of thought on his face, but the girl looked around blankly as if she had discovered something. , obviously, super high intelligence made her perceive other people's peeping.

Withdrawing his gaze, Su Yan wasn't looking at that girl anymore. He knew that if it lasted for a few seconds, the other party would be able to find the source of his observation and have a conflict with a girl with an intelligence of over 20. Su Yan didn't have that idea yet.

After walking around, Su Yan finally came to the classroom. When Su Yan arrived, the people inside were still almost full. The full classroom was full of people, men and women, and there seemed to be no empty seats.Frowning slightly, Su Yan walked from the front row to the back, and finally an empty seat appeared in Su Yan's sight.

Putting down the backpack, Su Yan sat on the empty seat, a refreshing fragrance came from one side, his head turned, and a girl's profile appeared in Su Yan's sight.

Su Yan's observation did not attract the girl's attention, and there was no conversation. Su Yan took out the books in the backpack.

Su Yan took out four books, "Basic Mathematics", "Blessing and Principles of Cardinal Points", "Hundred Years of Destruction", and "Firearm Maintenance and Expertise", which Su Yan read in the book in the morning. Obviously, these books are the most suitable for Su Yan to read now.

When he took out the book, Su Yan noticed that the girl next to him glanced at him, but this look didn't last, it was just a blink of an eye, so when Su Yan turned his head, the girl still returned to her original state .

Ignoring the other party's strange state, Su Yan picked up "Basic Mathematics" and read it. In his previous life, he had a lot of experience in studying science in college, so he used to pick up "Basic Mathematics" for the first book.After glancing at the preface and preface, Su Yan looked directly at the table of contents.Familiar characters appeared in Su Yan's sight.

A hundred years have passed in the human world, but the basic knowledge of mathematics has not changed. It is still a few operations of addition, subtraction, multiplication and division. read through.Seventeen points of intelligence, clear thinking, plus the study of mathematics in the previous life, the number of pages of basic mathematics decreased rapidly in Su Yan's hands. After more than ten minutes, the last page was opened by Su Yan. Su Yan's understanding of modern mathematics With a clear understanding.

The mathematics in this era has not changed much from the previous life, but the direction of application has begun to focus on the blessing of human cardinal points. Su Yan did not understand some questions about the blessing of cardinal points.After finishing basic mathematics, Su Yan planned to open "A Hundred Years of History of the Great Destruction", but the suddenly quiet classroom made Su Yan realize that something seemed to have happened.

Looking up, a thin old man with white hair appeared in front of the desk in the classroom, with a huge globe and a map of geography. Obviously, this thin old man was the professor who explained geography.

"What we call a global geography today"

The silence of the crowd made the professor start the lecture without any prelude, hung the map on the blackboard, pushed his glasses, and started the lecture.

"After the Great Destruction, the earth's environment has undergone a huge change. Radiation and viruses are the notable features of the change, and the high temperature is the biggest difference between modern times and a hundred years ago."

The professor's opening chapter attracted Su Yan's attention, and Su Yan closed the "Hundred Years of the Great Destruction" that was about to be opened. Compared with reading a book, it is obviously better to have someone explain it.

"The initial temperature after the nuclear explosion once reached more than 60 degrees, and some places even reached more than 80 degrees. At that time, human beings could not survive on the surface of the earth. Let humans almost go extinct" The old man spoke very slowly, some of which overlapped with Harry's.

"Later, continuous rainfall dropped the temperature from over 60 degrees to over 40 degrees. The rain lasted for half a year. It was because of this rain that human beings had a chance to survive the extinction of species. That year was called It is the year of rain. It is also called the year of heaven"

Two unfamiliar words came out of the professor's mouth, and Su Yan could hear the gratitude of human beings for the rain. A rain saved the lives and reproduction of several races, rain and heaven.

"After the sky fell, the world's climate began to ease, but the changes brought to the world by nuclear explosions have not eased. The change in the geographical environment is one of the most prominent items"
