Therefore, Yang Xiaotao did not choose to upgrade half a year ago, thinking whether it would get better after this period. Anyway, the credits have no shelf life.

After procrastinating, it took another half a year, and now, unexpectedly, the accumulated credits were enough to upgrade to level seven, which made Yang Xiaotao even more speechless.

This is because the system is urging him to upgrade quickly.

Putting aside the "Mechanical Principles and Structure" he had on hand, he had already thumbed through the book. He already knew the contents inside thoroughly. If he judged it by the credits given by the system, he would have reached the stage of mastery.

In the past few years, Yang Xiaotao has also figured out the rules of credit awards.

Even the mastery of reading is also linked to the credits.

At first, you can only get 1~10 points by reading in a hurry. Later, you can get 10~50 points by reading thoroughly, and 50~100 points by intensive reading.

After that, there is the reading comprehension in the upper level. If you reach the level of knowing it by heart, you can get about 200 credits. If you reach the level of mastery, you will get 300~500 credits. Finally, if you have mastered it, you will get about 1,000 credits.

.

Of course, high-level reading is also related to the quality of books.

A low-quality book can provide up to 100 points.

A high-quality book has endless possibilities.

Yang Xiaotao has read books in the past few years, and there are only two books that he has mastered at all levels.

One is "Mechanical Principles and Design" which I am reading, and the other is a paper on Mendel's Laws of Inheritance that I read three years ago.

That time, we spent a lot of effort and hard work to hybridize corn.

The credits given to Yang Xiaotao by the two books are also different. Mendel's book was only given one thousand credits, but this book "Mechanical Principles and Design" is obviously much thicker than Mendel's, so it was given one thousand and five credits.

More than mastering English.

Because of this, it took Yang Xiaotao one year to save up to 25,000 credits.

Looking at the credits on the panel, a long series of zeros, I feel full of pride.

But now, Yang Xiaotao, who heard the system prompts, decided to upgrade.

According to the current situation, it will not change if we continue to wait.

It's better to use it sooner.

Anyway, sooner or later it will be a knife.

Later, when the system prompt sounded, Yang Xiaotao saw that a year of hard work was lost in one fell swoop.

The effect is that Yang Xiaotao has a bunch of more experiences in his mind. These experiences are like a series of memories. Pictures quickly shuttle through his mind. In just a moment, he remembers the flashing pictures.

The last time I had body shaking, this time it was even more intense.

Especially the hands are more flexible in producing rhythm, and the brain feels the hands more clearly.

It's as if your hands are like a strict vernier caliper, that feeling is right.

In just one minute, Yang Xiaotao recovered from the shaking, only to find that his close-fitting autumn clothes were wet with sweat, and there was cold sweat on his forehead.

Yang Xiaotao stood up and stretched his muscles, then found clean clothes and changed into them before checking the rewards after the system upgrade.

"Sure enough, it's just as expected!"

Yang Xiaotao raised his head and smiled bitterly.

Upgrade to level 6 fitter and receive a reward of 1,500 yuan.

If you reach level 7 as a fitter, you will receive a reward of 2,000 yuan.

Then, it was gone.

Just money and fitter experience.

"Forget it, the national situation is difficult, and the national destiny is like this, the system must adapt to local conditions and seek perfection through humiliation!"

Yang Xiaotao saw this clearly.

Of course, it’s useless to look away.

Get up and get ready to cook.
Chapter completed!
