Ding Xuecheng hurriedly ran back to the rental house with the express package, and searched for a long time in the small rental house, but did not find scissors or paper cutters.

He ran to the kitchen, held the express bag in one hand and the kitchen knife in the other, gestured for a long time, and gave up.

In the end, he put the packaging bag on the square table, pressed the express packaging bag with his thin hands, bit the corner of the seal with his teeth, tilted his head, tore open the seal, and carefully took out a thin color picture book, which was the science textbook his mother bought for him on the Internet.

Ding Xuecheng was born on September 1 and enrolled in the first grade of primary school last year, but the school told him that he was under the age of six and could not apply for a school registration until next year. He also said that those born on August 31 would be able to go on, and for this reason, he secretly wiped his tears.

He finally turned six this year and went to elementary school as he wished, but he was almost a year older than his classmates. However, in terms of height and weight, he is younger than his classmates, which makes people suspect that he is not yet of school age this year.

Zhong Yuqing, the little chubby girl who sits with him, can almost be "decomposed" into two of him, so the two-seater table Ding Xuecheng can't always guard his side, whether it is "territory" or "airspace", he is always "violated" by the chubby girl. He whispered a few words, always defeated by the chubby girl's pink fist and threatening eyes, and gradually accepted the chubby girl's smug "smile" and chubby soft lily rubbing the sparse yellow hair on the top of his head.

The little chubby girl also privately gave him a nickname that made him sick to his stomach - "Dingdian", "This is a personality insult!" Ding Xuecheng's protests several times were ineffective, but it was better than calling out to the whole class and having to endure tears. He meditated hard for half a lesson, and in turn gave her a similar nickname - "Fat Girl", and threatened her: "If you dare to scream, I will scream too, who is afraid of whom!" ”

Big eyes to small eyes, turtles to mung beans, no one can help anyone, no one. This was the only half-time success in Ding Xuecheng's "diplomatic history", and he went back that day to eat an extra bowl of rice to celebrate.

On the second day of school, when the head teacher distributed the textbooks, he explained that the science textbooks were shared by two people in the same seat, and the little chubby girl was "kept" as a matter of course. When he was in science class, the little chubby girl raised her thick arms, like a circular mountain enveloping the exquisite science textbook, and did not share it with him, which made him suffer a lot.

A few days ago, when I was on a long-distance phone call with my mother, Xiaocheng said that there was no science textbook and begged my mother to buy one. Mom agreed, saying that she would order a copy online and send it to the school, so that he could pay attention to the courier collection. So, Ding Xuecheng went to the school gatehouse every day to ask the doorman's grandfather, and today he finally got it.

When Ding Xuecheng was three years old, his father and mother went to the south to work, and his grandmother and grandfather took care of him in his hometown. Ding Xuecheng didn't enjoy the care of his grandfather, but he talked to his grandfather every day. For as long as he can remember, his grandfather has never gotten out of bed much, always taking medicine, and the room is full of pungent medicinal smells. In addition to taking care of elementary school students, grandma also has to take care of grandpa. I heard that my father and mother went to work to earn money to treat my grandfather. Grandma's health is not very good, and she said that she has back pain and leg cramps. After leaving the countryside to attend elementary school in the city, my grandmother went back to her hometown to visit my grandfather every other day. Today, my grandmother prepared the dinner of elementary school, and went back to my hometown to visit my grandfather, and I will come back tomorrow afternoon. Therefore, Ding Xuecheng is the fifth time that he has spent the night alone in a rental house today. The first and second times he was so scared that he cried in the middle of the night and didn't dare to sleep all night; Now he is not afraid, he eats hot meals like little adults alone, finishes his homework, reads books again, and then washes and sleeps.

Today, Saturday, tomorrow Sunday, and "Teacher's Day", there is no need to go to class, he can completely own the science textbook by himself, and read it well.

Ding Xuecheng looked at the comic-like science textbook, which was a little strange, the cover was different from the science textbook they used. But on the cover, there are obviously two big red words - "Science", and there is a yellow block below, and there is a row of light red small words in it - "First Grade Book I"; In the middle oblate illustration is four children, two girls and two boys, with the black earth and trees in the distance. The word "science" is "floating" on most of the earth, and there is a "Pokemon" with a propeller on the head flying above the earth, and it is impossible to see what species it is; There is a green icon at the top of the cover, which reads "Approved by the Ministry of Education", and there is a line of small bold letters next to it "Compulsory Education Textbook"; At the bottom of the cover there is a line of smaller words "Guangdong Science and Technology Press" and "Guangdong Education Press".

Ding Xuecheng looked at the cover repeatedly, and finally came to the conclusion that the science textbook they were using was not the "Guangdong version"! - Okay, the textbook is available, but it is not what he needs, Ding Xuecheng couldn't help but be discouraged for a while, and the capital to show off to the little chubby girl was gone.

A child's bad mood comes and goes quickly. Ding Xuecheng looked at the "picture album" that his mother bought, and felt very warm, and his attention quickly shifted to the "picture album", after all, the attraction of "extracurricular books" is far greater than that of textbooks.

So, Ding Xuecheng carefully opened the cover, and what caught his eye was a small tree growing on the green grass, and two little girls were standing next to the tree. The small tree has three leaves and a green "flower bud" on the top, and from top to bottom, two yellow characters are written in the "flower bud" "table of contents"; A cartoon bee rests on the top leaf; In the middle of the large round leaf is written "Unit 1: Understanding Nature" and Lesson 1 to 4 topics; The oblate leaves at the bottom are written "Unit 2 Fruits and Vegetables", and below are the topics for Lesson 5 to 7.

Ding Xuecheng looked carefully for a long time and found that he didn't know the Chinese characters in it, but fortunately, they all had pinyin. He studied two preschool classes in a row, and the Chinese pinyin is still very good, and it is not difficult to understand even spelling and guessing.

Reluctantly turning to the second page, the structure of the picture is basically the same as the previous page: two girls are replaced by two boys; The little tree is missing the young leaf, and the little bird flies beside the leaves above it instead of the bee; The leaves on it read, "Unit 3, Our Stationery" and Lesson 8 to 10 topics; The leaves below are written "Unit 4 Four Seasons" and Lesson 11 to 14 topics.

Out of disgust with the domineering little chubby girl, he didn't care about the slender girl in the flower skirt in front of him, but he was very interested in the two little boys on the second page and looked at it carefully. The boy sitting on the ground has a chubby face, which does not match Ding Xuecheng's thin face; The little boy next to him with a basketball in his left hand and a sunhat on his head was very energetic, and his right hand was stretched forward, as if he was saying something......

The key is that the face of the "basket student" is also very small, which is somewhat similar to that of the elementary school students.

Ding Xuecheng looked at the characters in the painting fixedly, and muttered to himself: "How nice it would be if I were that boy!" I also like basketball~"

Slowly flipping through the pages, Ding Xuecheng forgot to eat dinner, and did not stop until the light in the room dimmed and his eyes were unbearably sore. Touching his deflated belly, he felt very hungry, so he put down his textbook and prepared a hot meal to eat.

Although Ding Xuecheng is only six years old, no, he is now seven years old, and he has long been proficient in the work of hot meals. He placed the small stool on the side of the desk, removed the pot of the rice cooker, washed it, put half a finger of deep water in it, and put the pot back; Put the rice in a bowl and place the bowl on the surface of the rice cooker; Put the rice in the grid, transfer the dishes to a small bowl, and then put them in the grid; Finally, close the lid of the rice cooker and press the rice cooking button; Dry your little hands, climb into a small stool, and plug in the power plug. When the rice cooker is "atmospheric", unplug the power plug, and you can eat hot meals after a while.

After doing this, Ding Xuecheng turned on the small table lamp at the head of the bed, looked at the "picture album" with relish, and quickly indulged in it.

When he felt sour again, he didn't know how much time had passed, and then he remembered that the water in the rice cooker might have boiled dry. He yelled "not good", got up and ran to the stove, and his beloved "picture album" fell to the ground and he couldn't take care of it.

Unplugged the rice cooker, opened the lid and looked, the water had already boiled dry, and it smelled a little mushy. However, the rice cooker cooking button has already "jumped" and entered the "keep warm" state. It wasn't much of a problem, he had encountered it many times before, but he wasn't too afraid.

Ding Xuecheng said to himself: "I have to clean the rice cooker later, otherwise grandma will definitely nag for a long time when she finds out!" ”

After Ding Xuecheng finished eating, he washed the dishes, chopsticks and rice cooker, and boiled half of the rice cooker to wash his face and feet. He closed the door and climbed into bed, wanting to read the "album" for a while.

Only then did he realize that the "album" had fallen to the ground, and hurriedly went to pick it up. Picking up the "album", Ding Xuecheng found that there was something on the ground, he touched it with his hand, it seemed to be a transparent plastic sheet, the size of an ID card or bank card, it was estimated that it was originally sandwiched in the "album", and the "album" fell out after it fell.

Xiao Xiaocheng held up the plastic sheet and looked at the lamp, which was completely transparent; It is also covered with the picture of the "album", and there is no change; Covered in words, unchanged; Blank in the air, still unchanged.

He really couldn't figure out what it was about, and he was holding plastic sheets all over the house.

The rental house is a one-way room, divided into two rooms, with a kitchen-dining room at the entrance and a bedroom at the back. In the bedroom, on the wall directly opposite the bed, there is a long mirror fixed with two Ding Xuecheng's height, which may have been left by a previous tenant.

At this time, Ding Xuecheng walked to the mirror with a plastic piece, and he found that what he was holding in the mirror was not a plastic piece, but a bright nebula, the same as the starry sky seen on TV. The nebula was spinning slowly, without sound, like a television screen with sound turned off.

Ding Xuecheng's mind was completely attracted, he was not afraid, and he forgot to be afraid, but kept getting closer and closer...... As a result, he really walked in.

Ding Xuecheng seems to have entered a peculiar space, as if there is a boundary, but surrounded by hazy starlight, boundless. There are four seats lined up in the space, like four sets of desks and chairs for elementary school students, and there are cartoon images on the tabletops.

Taking a closer look, Ding Xuecheng found that these four cartoon images were the four children in the "picture album", all of whom were elementary school students about the same age as him.

Ding Xuecheng almost didn't think about it, and went straight to the "basket" seat he liked and sat down.

The space in front of him fluctuated like the surface of the water, and the strange dog-like "Pokemon" dived out, with a big round head like a leather ball, bare, and the "propeller" on the top flew into the shape of a disc; thin eyebrows and big eyes, a pair of small black eyeballs dripping and rolling in the big white circles; The black nose as large as Mickey Mouse covers half of the face; Under the big black balloon-like nose, a half-moon-shaped mouth with upturned lips and bright red lips; Behind his head dragged a pair of long streamer-like ears, black; Small arms, calves, small stomach.

It circled a few times in the air like a dance on ice, and suddenly said to Ding Xuecheng: "Hello Bobo, I'm Beibei, and I'm your guide." Before you start your scientific journey, test your basic attributes. ”

Before Ding Xuecheng could be stunned, a burst of light fanned down, and a light curtain popped up in front of him, and a complete 3D model of his character suddenly appeared on the light curtain.

Character: Bobo (Ding Xuecheng)

Age: 7 years old

Height: 101cm

Weight: 16.5kg

Strength: 0.5

Constitution: 0.3

Endurance: 1

Dexterity: 1

Will: 2

Spirit: 3

Charm: 0.1

Lucky: 0

Status: emaciated, short, sub-healthy

Skill: None

The Starter Pack is not open.

Task: Not Picked Up

Bonus: None

Ding Xuecheng looked at the light curtain in front of him blankly, his thinking stagnated, and there was no movement for a long time.

"Bobo-san, I'm your guide, friend, and assistant, well, it's artificial intelligence. The name and data on the light curtain are your current basic attributes, I will explain it to you, and you should always pay attention to the changes in the data above in the future to understand your physical condition. The normal weight of a six-year-old child is between 18.4kg~23.6kg, and the height is between 111.2cm~121.0cm. Therefore, your current state: thin, short, sub-healthy, you need to supplement nutrition, get enough sleep, and insist on exercising~"

Ding Xuecheng was awakened by Beibei's voice, his eyes regained their agility, looked at the cute "Pokemon", and listened to every word it explained, and his heart was very happy. Growing up, he was so lonely, and he dreamed of having a good friend and a good playmate.

"It's nice to have such a good friend! Ah, my body is so bad, I'm obviously older than my classmates, they think I'm weak, and they always bully me, especially that little chubby girl! In the future, do what Bei Bei taught me, grow tall and burly, and see if you dare to bully me! Wow~ I can also play basketball! Ding Xuecheng thought secretly.

"Hello Babe! What do the following ones mean by height and weight? ”

"The average of normal adults at their peak is 10, and athletes, fighters, etc., will be above 10, while women, minors, the elderly, and the sick are all below 10. If an adult's strength is 10, he can lift 100 kilograms; Your strength is 0.5, which is only one-twentieth of an adult's, and you can lift 5 kilograms. The rest of the data is as understanding as this, and I'll tell you what those names mean. ”

"Oh, okay, I just don't know what those names mean, thank you Babe!"

"You're welcome, as a facilitator, it's my job. Physique is the comprehensive quality of the body, and in traditional Chinese medicine, it is the quality characteristics of the body formed by the rise and fall of the viscera, meridians, qi and blood, yin and yang, etc. Physique is formed by congenital heredity and acquired acquisition, and the inherent and relatively stable characteristics of human individuals in terms of morphological structure and functional activities are related to psychological character. The difference in individual constitution is manifested in some differences in response to and adaptation to external stimuli in physiological states, as well as susceptibility to certain pathogenic factors and the tendency of disease development in the process of pathogenesis. Therefore, the study of physical constitution helps to analyze the occurrence and evolution of diseases, and provides a basis for diagnosis and treatment of diseases. ”

"Beibei, I don't understand these~"

"Oh, get used to it, I'm sorry! Forget that you are still in the stage of enlightenment, let me explain it in plain language. For the more difficult content, I projected it on the light curtain and explained it against it. ”

Bei Bei said this, and a text appeared on the light curtain in front of Ding Xuecheng. ——

Constitution is a relatively stable feature of the human body in terms of morphology and function based on genetic variation. Specifically:

1. Physical morphological development level: body shape, body posture, nutritional status, etc.

2. Physiological and biochemical function level: that is, the metabolic function of the body and the working efficiency of various systems and organs of the human body.

3. Physical fitness and athletic ability: that is, the physical qualities such as strength, speed, endurance, agility and flexibility shown by the body in life, labor and sports, as well as the athletic abilities such as walking, running, jumping, throwing, climbing, climbing, draping, and supporting.

4. Psychological state: including proprioceptive ability, personality, interpersonal relationships, willpower, judgment, etc.

5. Adaptability: the ability to resist the external environment and cold and heat, and the ability to resist diseases.

There are many factors that affect people's physique, such as genetics, environment, nutrition, education, physical exercise, health care, lifestyle, etc., among these factors, school education, especially school physical exercise, has an important impact on enhancing students' physique.

Bei Bei explained the content on the light curtain in detail, and finally made a summary: "To put it simply, physique is physical condition. You're only 0.3 now, which is too far from the normal physique of a child of your age of 1.0, so you have to work hard~"

"My normal level for this age group is almost 1.0?"

"Well, that's pretty much what it means, your comprehension is good!"

Beibei's praise made Ding Xuecheng very happy, but when he saw the numbers 0.5, 0.3, and 0.1 on the light curtain, he couldn't help but be greatly discouraged, fortunately, there are still 1, 1, 2, and 3, aren't those 2 and 3 much higher than those of children of the same age?

Beibei's voice sounded again: "Endurance is the body's endurance; Agility is the speed at which the body reacts instinctively and nerves react. These two items are normal for you. ”

"The first four, strength, physique, endurance, and agility, focus on the physical body; The last four, Will, Spirit, Charisma, and Luck, focus on the soul. The first four items are easy to understand, but the last four items are not understood by you now. ”

"What's the use of those? Can you put it simply? A little bit will do. ”

"Well, to put it vaguely, will is a state of mind, which is the mental process by which people consciously, purposefully, and systematically regulate and govern their behavior, which can be understood as perseverance, self-control, etc.; Spirit, is the thinking activity of the brain, and the dark energy released by the brain tissue of the organism can be understood as the ability to remember; Charm is to describe a person's personality and beauty, and the natural exudation of likable feelings is a powerful force that can attract people and arouse the favor of others; Luck refers to the fact that good things that are difficult to happen actually happen, focusing on good luck, and is mostly used to describe people's good opportunities. It is lucky to realize your wishes and meet your needs. Whether you feel lucky or not depends mainly on your own wishes and needs. These are complicated, I'll talk about ...... later."

Ding Xuecheng vaguely felt that those were all "good things", how to obtain and improve? Bei Bei didn't say it, and he couldn't help it, so he dismissed it with a sentence of "I'll talk about it later". Especially that "lucky", it is actually 0, it is really aggrieved!

"Babe, what are we going to do now?"

"The first and second grades here are life experiences, please look at the light curtain."

Ding Xuecheng turned his head to look at the light curtain, and four lines of words appeared on it.

Main quest 1: Life experience.

Reward: One all-attribute enhancement solution.

Side quest 1: Get to know nature.

Reward unknown.

"Babe, is this a game?"

"Well, it can be used as a game! Note, you have to pay attention to answering the questions on the light screen at any time, and there is a reward for scoring high~"

"What's the 'All-Attribute Augmentation Liquid'?"

"A good thing to increase all the attributes of the character, you still have to think about how to get it first, hehe~ Bobo-san, are you ready?"

Ding Xuecheng didn't know what he was going to start doing, he just thought it should be fun, and replied loudly: "Ready!" ”

"So, let's start our scientific journey – the 'Science Gate' opens!"
