On the evening of the fourth day, at three o'clock in the morning.

Liu Ming's snoring is still like the exhaust sound of a modified car, and the pump is full of strength.

The porcupine also slept soundly, he was holding the cylindrical Thai latex pillow given to him by Zhu Tingting, and a string of shameful saliva flowed from the corner of his mouth, looking full of girlishness.

Under the dim light, after Kong Shucheng finished reciting a song of Li Shangyin's "Jin Se", he felt some pain in his cervical spine, and stood up and moved his muscles and bones. By the way, I rubbed my temples too.

The system turns on again.

Glanced at the points.

There are already 33 credits.

He was about to shut down the system when he suddenly noticed a vague rectangle floating in the upper right corner of the interface. The cuboid unknown object is exuding a faint halo at the moment, full of charm. At first glance, it looks like a chocolate chunk and a ......... Blackboard eraser.

What is this?

Kong Shucheng gently poked the glowing square with his hand.

[Welcome to the host, enter the application applet just launched in the system mall - "small blackboard knock"]

“.........”

Kong Shucheng subconsciously swallowed a saliva.

The system is produced and must be a high-quality product!

His instincts told him that this thing should be a good thing.

But I don't know, which is more disadvantageous between this "small blackboard knock" and the previous "multiple-choice shake".

If you don't understand, just ask.

"May I ask the system, what is the use of your 'little blackboard eraser'?"

[Ding Dong, dear host, this is a 'small blackboard knock', not a "small blackboard wipe"]

“.........”

Oh yes, yes, I got it wrong.

It's a knock, not a rub.

[Knock on the small blackboard, in fact, it is a small program product under the system mall, which focuses on solving the problem of "difficult book selection" encountered by the host when reviewing and taking the exam. Knock on the small blackboard, and you will know all the key and difficult points. 】

Oh, when you say that, then I'll understand in seconds.

In other words, this "small blackboard knock" can help me mark the key points?

Okay, this is good, this is good.

The key points of each subject in the college entrance examination, hurry up and give me a dozen.

[I'm sorry, all the black technology products launched by the system mall, the host needs to pay credits to purchase]

Well, I get that.

The things in the system mall are not surnamed Ma or Wang, and we can't eat and drink for nothing. Otherwise, there would be no point in accumulating credits.

Speaking of which, how many credits do you get for a key review of the college entrance examination in the year after tomorrow?

[Sorry, the host's top student level is not enough to have access to such services]

“.........”

After Kong Shucheng was ruthlessly disliked, he did not choose to give up.

He immediately thought of the final project of the "Mayor's Cup" ancient poetry contest.

Yes, yes, the system will quickly give me a key point, let me concentrate on reviewing and strive to be the first.

[I'm sorry, the final scene of the "Mayor's Cup" Ancient Poetry Contest is a test of the host's on-the-spot adaptability, and the interactive links are changing rapidly, and this system cannot provide a condensed version of the effective review outline]

“.........”

Kong Shucheng was a little powerless to complain.

Just said that his "level of academic tyrant is not enough", and now he says "unable to provide"?

How does he feel, this "little blackboard knock", a bit of An Dehai.

Two words: incompetence!

Immediately, Kong Shucheng thought about it carefully again and found that what the system said seemed to be right.

Listening to Long Piaopiao, there are many links in the finals of the "Mayor's Cup" Ancient Poetry Contest that are very interactive. For example, in "Flying Flower Order", the keywords are determined by random lottery on the spot, and it is impossible to predict which one it will be, and for example, the question of the poem solitaire is also random, and you can't guess how the opposing player will respond.

A game full of variables, of course, it is impossible to "knock on the blackboard and mark the key points".

Kong Shucheng felt a little discouraged.

Let's click in and see for yourself.

Without saying a word, he immediately entered the small program of "knocking on the small blackboard".

In an instant, rows of "service products" appeared in front of him.

When he looked closely, he was stunned.

Although the sparrow is small, I didn't expect that in this "small blackboard knock", there are almost all kinds of materials related to learning. It can be said that there is a lot of variety!

[Knock on the small blackboard, product No. 001: condensed version of high school Chinese review materials (with three detailed review reference books, and 50 compulsory question type simulation training for key circles) - priced at 999 credits]

[Knock on the small blackboard, product No. 002: condensed version of high school mathematics review materials (with nine detailed review reference books, as well as 50 key circle-based compulsory question type simulation training) - priced at 1999 credits]

[Knock on the small blackboard, product No. 003: condensed version of high school foreign language review materials (with three detailed review reference books, as well as 50 compulsory question type simulation training for key circles) - priced at 999 credits]

[Knock on the small blackboard, product 004: condensed version of high school physics review materials (with two detailed review reference books, and 50 required questions for key circle-type simulation training) - priced at 1099 credits]

.........

At first glance, it looks like a portal of revision materials related to studying.

Well, the price, it's an expensive horse.

Kong Shucheng dragged the interface down and found that the prices of most products were far beyond Kong Shucheng's existing purchasing power. He is like a low-income household full of ideals in his heart, and with only 33 yuan in his arms, he accidentally walked into the BMW fourth son store. He couldn't afford even the cheapest model.

Especially the "Condensed High School Mathematics Review Materials", which costs 1999 credits.

It's just sadistic.

Kong Shucheng was a little helpless, and the song "Cool and Cool" lingered in his heart again.

Just as he was about to close the "small blackboard knock", a "product No. 119" glowing green successfully caught his attention.

Wait, why "Product 119"?

This number......... Is there also a particular one?

119, isn't that what it means to "put out fires"?

Kong Shucheng looked at it again, and the goosebumps all over his body stood up.

[Knock on the small blackboard, No. 119 product: This product is specially tailored for the fourth audition of the first "Mayor's Cup" ancient poetry competition in Dongrao City, including a key reference book. - Price: 30 credits]

Oh my God, this is good!

There is nowhere to find the iron shoes, and it all depends on the "small blackboard knock".

In the past three days and three nights, Kong Shucheng has been bursting his liver uninterruptedly, although he has also gained a lot of knowledge of ancient poetry, but after all, the start is too late, the time is too short, and it is difficult to achieve the effect of overtaking in the corner.

Not to mention anything else, Feng Babai, who is in the first class of the second year of high school, can completely press Confucius to the ground and rub back and forth in terms of his ancient poetry reserves. Not to mention, there are also Zhou Luoxia and those top-level ghost animals in Class 0 of the second year of high school.

However, with this "product No. 119".

Perhaps, Confucius can see the Buddha and kill the Buddha, right?
