Unlimited progress

There are three classes in the afternoon in the third year of high school, and the third class is usually for self-study. Yao Ke took Lu Gao's seat at this time, and Zhang Xiaobai was going to teach him calculus.

"In fact, calculus is divided into differential and integral. Differential is to divide the x-axis into countless segments, which we mark as dx... and integral is the process of summing..."

As Zhang Xiaobai explained, there seemed to be a different kind of excitement filling Zhang Xiaobai's heart.

"Thank you, Zhang Xiaobai, I'll treat you to dinner later," Yao Ke said in a low voice.

[Ding, congratulations to the player for making up for his regret*1, reward: 1 free attribute point]

Is this also my regret? Explaining questions to someone I admire? If I ask him questions, will it also make up for the regret?

With only 20 minutes left before the get out of class was over, Zhang Xiaobai asked his own question:

"How did you learn Chinese and English? I memorized words and ancient poems, but I just couldn't improve."

"English is actually a system. It is not enough to just memorize words. You need to master grammar, common sentence patterns, and decorative techniques. Once you have mastered the rules, it will be easier. The so-called sense of language is the result of mastering all these things..."

"Chinese is learned through accumulation. In addition to memorizing ancient poems and classical Chinese, it is more important to accumulate materials outside of class. I usually like to read biographies, current affairs news, etc. The 60 points in writing are accumulated through extracurricular accumulation. In addition, writing style is also very important..."

[Ding, congratulations to the player for making up for his regret*1, reward: 1 free attribute point]

Zhang Xiaobai was in a good mood after getting another free attribute point. He just glanced at the task panel and found that the main task of the copy had not been completed yet. There was only more than an hour left for the task and he had to eat dinner soon. Did he have to make up for all the regrets before he could complete the main task?

What regrets do I have? Zhang Xiaobai couldn't help asking himself, but the bell for the end of get out of class rang, interrupting his thoughts.

"Let's go to the cafeteria, I'll treat you to a meal!" said Yao Ke.

Zhang Xiaobai did not refuse. Chen Ying and Tang Qin, who were sitting at the back table, also joined him. Along the way, everyone was discussing how many days were left before the college entrance examination and how they should study. Zhang Xiaobai felt a little melancholy.

As soon as he arrived at the cafeteria and looked at the 5-yuan meal in front of him, Zhang Xiaobai instantly felt like crying. He hadn't eaten hot rice since he entered the game. It was so delicious!

"What's wrong with you? Are you going to cry?" Chen Ying said from the side. Yao Ke and Tang Qin also looked over. Zhang Xiaobai had been silent all the way, as if he was worried about something. Now he was going to cry while eating?

"It's okay, the food is just so delicious. By the way, can you lend me some money?" Zhang Xiaobai thought of a scrap recycling station around the school where he could go to convert some raw materials. In fact, when he was going downstairs, he tried to convert the iron railings in the stairwell, but found that he couldn't.

Generally speaking, high school students don't have much money, with only a few hundred yuan a month for living expenses, and even less to lend to Zhang Xiaobai. Unexpectedly, Tang Qin was a wealthy woman and directly lent her 100 yuan. Yao Ke and Chen Ying only raised yuan.

After quickly finishing his dinner and taking more than 600 yuan, Zhang Xiaobai walked to the recycling station near the school without asking anyone to accompany him.

After passing through a small alley and turning a corner, he arrived at the scrap recycling station. Zhang Xiaobai looked at the large piece of scrap in front of him and couldn't help but get excited. The scraps that he had looked down upon before were now priceless treasures to him.

I secretly picked up a mineral water bottle and tried to convert it, but it said again that it could not be converted. It seems that only the items I own have the power to convert?

After wandering around for a while, Zhang Xiaobai found the owner of the recycling station. The owner was a middle-aged man in his forties or fifties. He originally collected junk, but he didn't expect that someone would come to him to collect things.

Originally, he had his own sales channels and would not sell things to other people, but Zhang Xiaobai begged here, saying that his school had a practical activity on waste utilization and he wanted to turn waste into treasure by himself. In addition, Zhang Xiaobai was willing to pay a high price for the recycling.

Two years of experience as a Didi driver made Zhang Xiaobai no longer have the bookish air of a student. Instead, he had the air of a seasoned veteran. After some coaxing and deception from Zhang Xiaobai, the owner of the recycling station finally agreed to sell the product to him.

An old TV for 100 yuan? Buy it! An old refrigerator for 100 yuan? Buy it! A washing machine for 100 yuan? Buy it! These big items cost Zhang Xiaobai half of his savings, but Zhang Xiaobai didn't feel bad because there was a lot of metal in them!

"Boss, I don't want good things! The worse the better! We need to develop our hands-on skills."

The boss was a little confused, but still threw out a pile of things that were broken beyond repair.

A tricycle without wheels, a fan with only one blade, an air conditioner with only an outer frame... Zhang Xiaobai bought all of these things and was even excited inside. The most important thing was that they were cheap!

Since there was not much time left and the main task had not been completed, Zhang Xiaobai hurried to pick out some large items, including sponges and a lot of rotten clothes.

"Boss, that's all. Just help me move it to the gate. My classmates will come to move it away later." Zhang Xiaobai and the boss calculated the price, which came to 630 yuan in total, and Zhang Xiaobai only had 5 yuan left.

The boss instantly felt that this guy had great potential and was more like a rag collector than himself! However, making 200 yuan at this time was not bad, so he helped Zhang Xiaobai move the pile of rags to the door.

When the boss turned around, Zhang Xiaobai decisively used his transformation ability.

[Are you sure you want to convert the washing machine to 0.5 units of metal, 0.2 units of plastic, and 0.1 units of magnet? ]

"Magnet?" Another new raw material. Isn't this a necessary material for making electric cars? What a surprise.

[Are you sure you want to convert the TV to 0.3 units of metal, 0.1 units of plastic, 0.1 units of glass, and 0.1 units of magnet? ]

[Are you sure you want to convert the clothes into 0.3 units of cloth? ]

...

A series of pleasant sounds rang in Zhang Xiaobai's ears until all the objects in front of him disappeared. Zhang Xiaobai glanced at the system panel:

Raw materials: wood 6.0, metal 3.5, rubber 3.1, plastic 1.5, glass 1.2, cloth 4.0, charcoal 1.2, magnet 1.0.

All raw materials exceeded 1 unit, especially there was an additional raw material, magnet, Zhang Xiaobai was very happy.

"I smile triumphantly, I smile triumphantly..." Zhang Xiaobai walked back humming a song. He thought that he still had a regret that he had not made up for. Perhaps this was his biggest regret.

However, just as he reached the corner of the alley, Zhang Xiaobai heard an arrogant voice.

"You little bitch, you dare to ask your sister to come and cause trouble for us? You are very capable, just shout again! No one will help you even if you scream your throat out this time."

It was a girl's voice, and she seemed young. School bullying? This place was close to the school, so she must be a student.
