"Come back, when passing by the entrance of the community: 'Uncle Zhang, I brought you a chicken leg!'"

  Zhang Shuobo smiled and took it over: "A Xin, why are you back so late today? It's almost 10 o'clock at night."

  He went to Jing She, ready to learn some swordsmanship. Fang Xin's skateboard flashed by in an instant, rushing towards his small house, leaving Zhang Shu looking thoughtful.

  The residential area is lush and green, with a cool and refreshing atmosphere at night. In fact, the greening of this world is more than ten times stronger than that of the original Earth. Fang Xin had gotten used to it naturally before, but now he couldn't help but sigh in admiration. Not to mention other things, just look at the roadsides, behind those long wooden benches are dense green trees and some unknown flowers, making people feel relaxed and happy.

  Due to this body's biological clock, returned home, washed and brushed a bit, pounced onto the bed, adjusted the room temperature, and fell into sleep.

  Until tomorrow, the biological clock woke him up again, and he sat up in bed with a start, walked into the bathroom to wash his face, and then ran directly to the balcony. Sure enough, in the dark and bright moment, from the east, accompanied by the first ray of sunlight, the purple haze filled the sky instantly.

  To absorb the essence of the sun, one must have inner substance. Only when the primordial energy has been accumulated for a long time can one stimulate the lower abdomen and face the rising sun to take deep breaths. This is called the resonance of essence and primordial energy. Naturally, it becomes the art of inhaling and exhaling. After twelve times, you will feel that your body's inner breath is full, then stop and return to your room.

  This kind of Qi is precious and lies in persistence, taking the meaning of continuous and unbroken, cannot be taken more than one day.

  After having breakfast, Fang Xin opened his computer.

  Arrived at the "Education Network", logged in, skillfully entered the password, and entered his own page.

  Now education is divided into basic education and vocational education. Basic education is the foundation of all subjects, including basic mathematics, basic language, basic history, basic social common sense, basic skills, basic physics, and basic chemistry in this country.

  To say, the rest is nothing special, but basic social common sense is a very special place, which is divided into ten items and combined with basic skills. To say, Fang Xin's making dolls can also be considered a basic skill.

  Fang Xin has completed the basic skills of: making cloth puppets, basic painting, and brush calligraphy, which have already met the credit requirements. If he learns one more skill in swordsmanship, he can earn even more credits.

  The most special thing is the skill tree. For example, for any citizen, the basics must be learned, which is a compulsory subject to learn, but once the basics are completed, some subjects do not need to be learned at all, and instead climb the skill tree - learning literature-related subjects, high school math does not need to be learned, learning physics-related subjects, foreign languages and so on do not need to be learned.

  For every skill level upgrade, you can take academic credits and be awarded a certificate, which will serve as proof of your profession in the future. Of course, advanced skills require a lot of foundation, such as intermediate history, which involves basic social and political science content, which won't be introduced one by one here.

  After browsing through the credits, combined with Fang Xing's original memory, I knew that I could only be considered a mediocre student.

  Fang Xin is currently taking courses in Second-Year Mathematics, Second-Year History, Basic Socio-Economics, Basic Socio-Politics, Second-Year Physics, Second-Year Language and Literature, and Second-Year Classical Chinese, with no foreign language courses.

  I took a look at the second-level math and found that it's not much different from what's on Earth, basically just junior high school curriculum with no significant difference. Then I looked at the third-level math and found that it's roughly equivalent to high school content. After reviewing some online textbooks and last year's math exam papers, I realized that as long as I review a bit, advancing to third-level math shouldn't be a problem. As for fourth-level math, it's basically college-level math content, mainly calculus, which can also be passed with a year of review.

  Then click.

  "Fang Xin, student ID C-YJX-7842, please confirm whether you want to participate in this semester's second-level math exam." A female voice prompt appeared on the computer webpage.

  "Yes!"

  "Fang Xin, student ID C-YJX-7842, is it confirmed that you want to add third-order mathematics to your learning skill tree?"

  "Yes!"

  "Fang Xin, student ID C-YJX-7842, are you sure you want to add 4th-order mathematics to your learning skill tree?"

  "Yes!"

  "Application approved, course permission has been opened, are you continuing with the original instructor or choosing a new one?"

  At that moment, the entire skill tree had several more gray options, and a batch of math teachers appeared below, each with evaluations and ratings. Fang Xin didn't care about this, as he had already mastered these items, and the quality of the teacher's guidance was not very relevant to him.

  Only the original instructor would be clear about his level, although he can say that he made progress in learning during the self-study period, it's also a bit troublesome, so he randomly chose a new female teacher to participate in the work.

  "You have chosen mentor Lin Yanran, credits and mentor relationship are recorded, mentor space is established, and email and message are sent, archived at the Public Education Office."

  Don't think that self-study can be chosen at will, this is a matter of consuming tuition fees and social credit records. The speed and quality of completing courses are included in the evaluation of citizens' quality and credit column.

  Fang Xin didn't mind, he closed this item and entered the next one, making arrangements for other subjects. He found that although the world was different, many principles were still applicable. The views on society in basic social politics and basic social economics were somewhat different, but there were still many similarities. With his current level of study, he could quickly resolve them.

  The only thing that cannot be solved quickly is history.

  The degree of secondary history is to systematically sort out the entire historical dynasty, grasp the important events and influences of each dynasty, but do not make too specific requirements for time and names - that is the degree of tertiary history.

  The Xia, Shang, Zhou, Qin and Han dynasties. History took a turn in the Tang Dynasty, and subsequent history, dynasties, events, and known history were completely different. The Huaxia Han regime no longer had successful invasions from foreign tribes on the grasslands, although there were several changes of dynasty, but the orthodox continued to this day, and established its position as a world power.

  Fang Xin didn't bother to think about why, and at this moment, the information was transmitted. Fang Xin no longer delayed, opened the mentor space, and suddenly, the on-site teaching model was activated.

  Lin Yanran appeared on the screen, only twenty-three years old, with a background of lush cherry blossom trees, wearing a white dress, set off by her snowy complexion, elegant and refined. The people in this world seem to be of high quality, whether male or female.

  Lin Yiran also saw the boy on this side of the screen, who was staring at her with a dazed expression. With just one glance, the boy attracted her attention, as if he had some kind of mysterious aura about him.

  But of course no one really lost their composure, Fang Xin automatically greeted him and slightly bowed his head: "Hello, Director Lin."

  "Fang Xin, hello, your student ID is C-YJX-7842, you chose math courses from second-order to fourth-order?" At this time, Lin Yanran said seriously: "Are the chosen courses a bit too many?"

  "It doesn't matter, I want to study seriously and spend a few years on it."

  "Since that's the case, I'll test your level first so we can proceed with the lesson. What level have you reached now?" Lin Yanran didn't usually engage in small talk with her students at times like these.

  "The second stage is already completed, and the third stage has just begun, but the second stage has not been tested yet." Fang Xing quickly replied: "There are textbooks for the third stage at my home, I'll learn some first."
