I, Yan Jiefang, will live to 2025 in this courtyard house.

After walking slowly for about a kilometer, Yan Jiefang found a quiet open space with few people.

He hung his schoolbag on the railing and then began practicing radio calisthenics.

The name of the third set of broadcast gymnastics is very much in line with the spirit of the times: "Colorful Sunshine".

There are nine sections in total: preparatory section, stretching exercises, chest expansion exercises, leg kicking exercises, side bending exercises, torso rotation exercises, abdominal and back exercises, jumping exercises, and whole-body exercises.

The entire set of exercises took nearly 5 minutes, and my body felt slightly warm.

It's no different from doing regular exercises.

Upon opening the panel, I found that my physical fitness had not changed at all, and my score for radio calisthenics was still 41/100.

Obviously, things aren't that simple; you can't improve just by practicing once.

However, given the precedent of the critical hit system, he had no choice but to believe in this cheat system.

As an adult who has been through the harsh realities of later society, he still possesses the necessary patience.

After closing the panel, he immediately began the second round of practice.

After five repetitions, Yan Jiefang began to sweat slightly, feeling warm all over.

After doing it ten times, he felt a little hungry, and at the same time, he was sweating profusely, and even his head started to steam.

Feeling a bit tired, Yan Jiefang stopped practicing, took out a steamed bun, and started using it.

At the same time, he glanced at his personal panel.

My physical fitness remains unchanged, but my proficiency in radio calisthenics has improved by two points, now it's 43/100.

Although it wasn't as useful as I had imagined, it wasn't completely useless either.

After all, this cheat is only at a basic level, so it's understandable that its effect is somewhat lacking.

After eating half a bun, he felt he was almost full, so he put the remaining half away.

Feeling a bit thirsty, Yan Jiefang decided to temporarily stop practicing and take a break to read a book.

He found a stone stool to sit on and took out his junior high school algebra textbook.

This textbook has several tears, and there are several different names on the title page and side pages.

Besides himself, Yan Jiefang, there are four other names that are all over the place: Lin Moshu, Xie Wanning, Gu Yanqing, and Yan Jiecheng.

The blank spaces in the textbooks were filled with all sorts of scribbles, notes, and little drawings.

Clearly, this is a textbook with a story!

And its story will continue after he graduates.

At the very least, we won't need to buy textbooks for Yan Jiekuang and Yan Jiedi anymore.

Fortunately, the original content of the textbook is still there. As long as you can ignore all the messy stuff mentioned above, it won't affect your studies much.

After browsing through the table of contents, Yan Jiefang discovered that the content of the third year of junior high school during this period was much simpler than that after 2000.

The topics are: quadratic equations in one variable, the relationship between roots and coefficients, quadratic functions, simple statistics, and an introduction to logarithms.

Although he hadn't been to school for many years, he was a science and engineering student before he transmigrated. After spending some time briefly going through the whole book, he basically understood the essence of this algebra book.

Looking at the panel, my proficiency in junior high school math has indeed exceeded 85, and is now 91!

I estimate that after he finishes reviewing geometry, he might score over 95 in that subject!

If I spend more time cultivating my skills and addressing my weaknesses later, I'm sure getting perfect scores every time won't be too far off.

As the sun was already overhead, Yan Jiefang put away his books and began his return journey to courtyard number 95.

Back home, Yang Ruihua had already prepared lunch.

It was still the same old mixed grain steamed buns and cornmeal porridge.

Ignoring Yang Ruihua's stern expression, Yan Jiefang quickly finished the corn porridge, so thick it reflected his image, in a few gulps.

He summoned his third brother, Yan Jiekuang, to his room and gave him the cornbread he hadn't eaten at noon.

Yan Jiefang went to the kitchen, grabbed a large enamel mug, filled it with cooled boiled water, and left the yard without looking back, carrying his schoolbag and the enamel mug.

With access to thirst-quenching boiled water, he spent the entire afternoon practicing radio calisthenics in a relatively secluded spot on the Shicha coast.

After spending 4 hours and several large steamed buns, Qicai Yangguang's proficiency level increased to 51.

At the same time, although his physique was still weak, it did improve a little, reaching 5.

The next day was Saturday.

There are no weekends off during this period; you still have to go to school or work on this day.

Yan Jiefang did radio calisthenics all day long.

After a full day of practice, his physical fitness improved a little more, reaching 6.

Although it is still far from the average level of healthy adult males, it is not too weak for a junior high school in this difficult period.

It's 50% stronger than when I first transmigrated here the day before yesterday!

With a little caution and an adult mindset, an average student might not be a match for him.

Dealing with that student who made those threats and Pang Dahai shouldn't be a problem.

After all, after a long period of hunger, their physical condition was not much better than it was before Yan's liberation, probably only around 4 points, definitely not more than 6 points.

In the evening, the family gathered around the dining table to eat their dinner.

Yan Jiefang couldn't eat anything, and he wasn't hungry. After finishing the cornmeal porridge, he wanted to leave.

Yan Bugui stopped him, glanced at the children, and slowly spoke:

"You all know the situation at home; we're almost starving. Luckily, tomorrow is Sunday, so you can all rest."

He paused for a moment at this point.

Actually, everyone knew what he was going to say.

Yan Bugui then spoke:

"It just so happens that the wild vegetables outside the city, such as shepherd's purse, dandelion, and bitter greens, are at their most lush and delicious. I've taken you to dig them before, so you should all recognize them. Yan Jiecheng, tomorrow morning, take your younger brother and sister to Zuojiazhuang to dig up some more, which will help lighten the burden on the family."

Yan Jiecheng was very unhappy. He finally had a day off tomorrow and was planning to go shopping at the department store. He immediately retorted:

"Dad, aren't you off tomorrow too? Why don't you take them?"

Yan Bugui leaned back slightly and glared at his eldest son:

"Why are you so unreasonable, child? I'm just taking advantage of my break to go for a stroll over Shichahai Lake. Maybe I'll catch some big fish and bring them back to improve the family's meals."

Yan Jiecheng looked disgusted.

"Dad, how can you say that? When have you ever come back empty-handed? Even if you occasionally bring back one or two small fish, you have to pickle them and save them for the New Year! I've heard that you sell all the fish you catch to the purchasing department of the steel mill!"

Upon hearing this, Yan Bugui immediately raised his voice slightly:

"Jiecheng, you're not young anymore. You'll be 20 this year, which is the age to get married! What am I selling this for? Isn't it to save money for your wedding?!"

Mentioning this, Yan Jiecheng immediately felt as if his vital point had been stepped on, and his desire to retaliate vanished instantly.

He has indeed reached the age where he wants to be with women.

He still dreams of moving out and living separately after getting married.

Yan Jiefang watched from the side, inwardly scoffing: The boss is no good at all!

As for himself, he is currently in a phase of quiet development and should not cause any unnecessary trouble.
