A map appeared, a red dot kept flashing, and was logged into the private computer.

  Fang Xinxin felt something, everything was ready, then came out of the nutrition warehouse, washed and dressed, he was a boy, half an hour was enough.

  With this information, when taking public transportation, the personal computer and public system are connected, and after entering the route, it can naturally remind you to transfer buses and shifts. Fang Xing didn't know the way, but still arrived at his destination smoothly.

  The street scene is quite deserted, with few people on the quiet streets, and there are various shops and supermarkets on both sides. Although it's not too dirty, you can feel the atmosphere, this is a slum in this world.

  Fang Xin quickly found the location, which was a large building, but it looked very old from history. It had twelve floors, and each floor was drying its own quilts and clothes, looking like a country of ten thousand flowers.

  Looking at all this, Fang Xin felt a mix of emotions. His own villa and nutrient warehouse were luxuries that ordinary people in this place could hardly obtain. Even in this world, only the most basic food rations were guaranteed; everything else had to be earned through hard work.

  He's not unaware that it's already quite difficult for society to achieve this point, but such feelings are naturally produced.

  Only those who have the capital and leisure can come to do good deeds and accumulate merits.

  She went up to the tenth floor, knocked on the door, and out came a middle-aged woman who already knew about the information. The woman's name was Jin Zhaowen, 36 years old, with a dignified appearance but a tense face.

  "Who are you looking for?"

  "I am Fang Xin, through Huaxia Charity Union, I heard that you need a home tutor?"

  Jin Zhaowen hastily revealed a smile: "It's actually Teacher Fang, I didn't expect you to come so quickly, please come in, please come in."

  For the sake of her child, she naturally showed her most enthusiastic side.

  Fang Xin showed a shy expression, he knew how to gain her trust and make her feel more at ease.

  Jin Zhaowen let him in, and on the other hand, she felt a sense of melancholy. The tall and handsome face was nothing special, but what struck her most was that kind of refreshing and carefree aura.

  This temperament can only be acquired by those who have experienced great hardships and sufferings.

  "Please sit down, I'll go call Xiao Tong."

  He rushed over with the tea, and as he handed it to Fang Xin, he couldn't help but notice that the other person's fingernails were extremely short, with some even having thin calluses, while his own hands were fair and smooth, almost like a girl's delicate skin.

  He felt a bit awkward and hastily took it himself, taking a sip. The tea was slightly bitter. Taking advantage of her departure, Fang Xin looked around the place.

  This is a very cramped home, although there are electrical appliances and furniture, but it's obvious that they're all old. Two rooms, one for the couple and one for the child, the kitchen and bathroom are narrow and dimly lit.

  In just a few minutes, someone gently pushed open the door and approached cautiously.

  Fang Xin looked back, but it was a little girl, with clear black and white eyes, only twelve or thirteen years old.

  He was somewhat surprised, originally thinking that his opponent was a mischievous kid who didn't study well. Now it seems that learning first-grade math is already ahead of schedule.

  "Quickly call Teacher Fang, and from now on you must study well with Teacher Fang." Jin Zhaowen hastily said.

  Suddenly, he understood.

  Another hope of changing one's fate through reading, piling a lot of homework on the child's young shoulders, and he can't help but feel a little sympathy.

  After coughing slightly, he said: "Wu Dandan, hello, I'm Fang Xin."

  Wu Dandan gazed into his eyes, then stepped forward, stretched out her small hand, and the two of them seriously shook hands.

  "Miss Wu Dandan, I'm here to help you study. I hope that in two months, we can both gain something." As he held her hand and spoke, a faint, invisible light flashed from the Jade Ruyi within his body.

  Wu Dandan was stunned for a moment, then her eyes cleared up and she nodded vigorously.

  "Then let's get ready, I want to see your current level." Fang Xin said, he had just used the precious Jade Like Intention's energy to activate a weak prayer technique, making the other person full of good feelings, all for a good start.

  Wu Dandan nodded and didn't say a word, pulling him into her own room.

  Jin Zhaowen was somewhat surprised. Wu Dandan had always been quiet and taciturn, quite out of place, why was she so close to him?

  The door was half open and you could see inside.

  Fang Xin began to ask Wu Doudou about her homework and had her work on math problems from time to time, immediately calling up the corresponding teaching course.

  "Natural numbers are what we naturally use, understand? They're the numbers 0, 1, 2, 3, 4, 5... and so on, one after another, all the way to infinity, no negative numbers."

  "What is a negative number?"

  "Numbers less than zero are marked with a negative sign -, for example, if you have ten dollars, it's a natural number. If you owe someone ten dollars, it becomes negative ten dollars when recorded. As for rational numbers and irrational numbers, we'll learn about them slowly and understand later. Come on, let's do another exercise."

  Jin Zhaowen watched from outside the door crack, feeling relieved. She quickly took out meat from the refrigerator and cut it into shreds.

  Not much time had passed, at dusk, Wu Zhenggang came back from work. As soon as he entered the house, he saw the two people studying inside. He immediately moved quietly, helping his wife with cooking and setting the table while whispering to her: "Ah, there's a teacher here, looks very young?"

  "Ah, he's a student at Town Tech Academy. Look at his profile, he's only 15 years old this year, and he's already in third-year math, while all his other subjects have ended at second-year level. At his age, he's really a good student!"

  Wu Zhenggang carefully looked at the information on the computer for a long time before saying, "That's great! If Dandan can be like him, I'll be happy."

  "Don't just stand there, hurry up! Today we'll make a good dish. Teacher Fang doesn't want any money, but for the first meal, it should be made more sumptuous. You go to the supermarket and buy some more."

  Wu Zhenggang nodded, gazing at his wife: "Zhao Wen, it's been tough on you. Ah, this year our department said I have a free training opportunity, after completing it, my salary will increase by 30%. I hope that from now on, we can pave the way for our future and not let our daughter suffer because of me."

  Wu Zhenggang had just returned when Dandan finished today's lesson. Taking advantage of the time, Fang Xin also completed the plan book.

  Pulling Er Gou out, Fang Xin said seriously: "Two of you, come over here!"

  The couple hurriedly washed their hands and came over, sitting on the sofa.

  "Mr. Wu, Ms. Jin, I'd like to ask, your requirement is to finish the first-year math within this year, right?"

  "Yes, Teacher Fang, this is what I hope for."

  "Okay, one semester of math, with 200 teaching hours, tailored to Dandan's current level and state. I think it can be completed within two months, with three hours of teaching per day, and several hours of homework, for which I have already made a plan, please review."

  "Two months?" Both of them looked at each other in dismay, this time seemed a bit short. Normally, it would take a year to learn, and even with intensive teaching, it would take half a year.

  Wu Zhenggang took Fang Xin's computer and looked at it, with dense teaching materials on the screen. He felt dizzy after looking at them, but his confidence in Fang Xin increased: "Teacher Fang, you are a professional, so please handle it yourself. As parents, we will definitely support you."

  "The child's learning ability has a limit, and completing it in two months is already a very tight schedule. I will leave out the necessary rest time, please don't increase the course randomly." Fang Xin said seriously: "This is my only requirement, otherwise, I can only ask for someone else to take over."

  The power of Yu Ruyi is currently very weak, but can maintain three hours of deep learning, after which a full rest is required, so this condition is necessary.

  "Of course, of course." The couple hastily replied in unison.

  "Sign it then!" Fang Xin printed out from the printer at home.

  The two men looked at each other and then signed.

  It ended up like this, and after eating a little dinner, Fang Xin directly bid farewell. After going out the door, he didn't go back home but instead went to An Yi Jing She. As it happens, he has sword practice homework every day.

  In actuality, the early practice of swordsmanship basics is nothing more than basic training. The fundamental principle lies in the mind reaching the hand, and also training neural reaction speed, to achieve a state where one can cut or thrust steadily, with power and accuracy, which is roughly sufficient.

  Many people trained for three months and declared the end of basic swordsmanship, but Fang Xin was prepared to train for a whole year. Of course, if Yu Ruyi could accumulate power as expected, he could speed up the process.
