Before going out, Ding Xuecheng looked at the time, 7:30. The rental house is only seven or eight minutes away from the school, and it is still early to arrive at the school at 8 o'clock.

He found a flower bed in front of the bank, walked over to a stop, and pulled out the learning machine that looked like a thin board from his school bag.

This is not the learning machine he saw in kindergarten children at all, nor is it the learning machine he saw on TV, the whole thing is a thin pure black "plexiglass plate"! Thinner than a regular smartphone, it has no graphic logos, no buttons, and not even the slightest gap......

There are three holes on the side of the "thin plate": one seems to be a headphone jack, one seems to be a mobile phone card slot, and there is a USB socket. He has repeatedly studied his mother's mobile phone, and he has also seen the iPad of kindergarten children and the teacher's laptop, and he knows all these interfaces.

"Why is there no charging or data cable interface? The whole is one, tightly fitted, and definitely not on the battery. What happens if it runs out of electricity? Or will it never run out of electricity? Maybe it's not purely electric."

Ding Xuecheng looked sideways and vertically, turned it over and turned it upside down, and couldn't figure out what it used as energy; The screen is full of messy spots, and there is no boot.

He was a little helpless, so he could only spend points to ask Bei Bei for advice.

Ding Xuecheng called Bei Bei dissatisfied: "You must have done it on purpose!" How to use the learning machine? ”

"2 points."

"Buckle it, say it quickly!"

"This learning machine simulates the design of the iPad in reality, with an appearance size of 202.1mm*135.4mm*6mm, a weight of 160g, equivalent to a 7.9-inch tablet, a resolution of 2224x1668, a storage capacity of 256GB, built-in WLAN and a 1200W pixel dual HD camera. It is equipped with an external headphone jack, a SIM card slot for mobile phones, and a USB port. Voice, palmprint and iris recognition, voice and touch screen control, emulating the Android operating system, with all the features of today's smartphones. [Note: The core module data and all programs are confidential, the running software is bound, cannot be uninstalled and installed, and can be upgraded by spending points.] The energy consumption method is integral, and solar energy is assisted charging. 】”

"Wow, this is the smartphone I've been dreaming of! It seems to be more advanced than smartphones! ”

"That's nature."

"You don't need to recharge? No wonder you can't find the charging port! How many points do I spend per day? ”

"Bind the user for the first time. Under normal circumstances, solar energy charging can fully meet the needs of use; Without the use of solar assistance, standby consumes 1 point for a week, and about 1 point for a day of normal use. ”

"It's okay, it's okay to bask in the sun, so I'm reluctant to spend points. This learning machine also has each logo, which side is the front? ”

"There is no positive or negative side, and there is no difference between the upper and lower ends, they are all used the same."

"Awesome! There is no need to distinguish between positive and negative and backward, you can use it when you hold it. What other special features are there? Can you make calls and videos by inserting a mobile phone card? ”

"Grope for yourself, 2 points service is over."

"Slow, you haven't said how to turn it on!"

"I'm by you! Voice 'power on' with a prompt at the back. ”

Ding Xuecheng saw Beibei's explanation on the light curtain, his heart was so beautiful that he couldn't find the north and south, and he was stupid enough to ask "can you make a phone call and video", no wonder Beibei was angry.

He whispered to the "square", "Turn on." ”

At this time, a palm pattern appeared in the center of the screen, Ding Xuecheng made a gesture, found that it was his left hand, and immediately stretched out his left hand and pressed it. A bright colored line scans all the way down from the top and back to the top to indicate that the palm print is locked.

Then a pair of eyes appeared on the screen, which meant that the iris had been scanned, Ding Xuecheng lowered his head and leaned in, his eyes facing the screen. The colored bright line is scanned back and forth horizontally and vertically, showing that the iris is locked and turned on smoothly.

The entire screen of the learning machine lights up, and the desktop background pattern on it is actually the cover of the science "picture book": the upper end is a prompt that there is no SIM card inserted, as well as signal strength, WLAN signal, time and solar energy slot; In the middle are gadgets such as recording, radio, repeating, playing, calculators, drawing, notepads, clocks, calendars, lighting, compasses, mirrors, etc.; There are also icons for camera, phone, contacts, text messages, browser, and more at the lower end of the screen. The entire layout is the same as a smartphone.

Ding Xuecheng saw that the three binding recognition of the learning machine had been completed, so he put the learning machine into his schoolbag, walked to the school, and whispered: "This learning machine is good, but it is too big, and it is always troublesome to be discovered by classmates or grandma when using it." ”

The light curtain suddenly flashed open, and a line of words appeared on it: "The software can be upgraded with points, but the hardware can't be reduced, and you can exchange the points for improved ones in the future." ”

"Improved? Is it any wonder that this is called a prototype, and the improved version is very small? If it's too small, the screen will be small, how can a screen like an old man's machine go online? ”

"Don't think too narrowly, the more developed the technology, the smaller the host can be, the watch style, button style can be; The screen does not have to be a physical object, it is displayed with a light screen, as big as you want, and there is a difference in energy consumption. Watch more science fiction movies, which are in Star Wars. ”

"Hell, that's science fiction, it's not real!"

"Haha, you know the story of the frog at the bottom of the well, right? The frog at the bottom of the well thinks that the sky is only the size of the mouth of the well, what do you think? ”

"Also, the illusion space has come out, what else is impossible!"

"Yes, discipline and fantasy are twins, and the realization of fantasy is the eternal goal of science, work hard, Sao Nian!"

"Beibei, you took the initiative to 'speak' to seduce me to redeem new equipment as soon as I have points in the future? It's uncomfortable to see that my learning machine didn't spend points? Huh? I really thought of a question: sometimes I ask a question and you want points, and sometimes you take the initiative to explain a lot of questions and don't want points, what's going on? ”

"yes, why do you sometimes want points, sometimes you don't, and you're quite positive? I want to think about ......"

"You think this is too big a learning machine, I can't get angry before I take the initiative to explain."

"No, you took the initiative to tell me about the advantages of the improved learning machine, because you wanted me to change to the improved learning machine. If I change it, what will happen to this one? Others can't use it. How many points does this one need to redeem? How many credits do you have for an improved learning machine? ”

"This learning machine has 5,000 points, and the recovery price is 1,000 points; The improved type has 10,000 points, 50,000 points and 100,000 points. ”

"Haha, it's exposed! This time, you didn't ask for points, you felt that there was a business to do, and you ran out, you really look like a businessman. ”

"Hehe, I'm reminding you of the purpose of your points, and this time I confiscated your points."

"Yes, you want me to redeem expensive items for free, and you charge when I feel like I have no business to do! You thief and thief! ”

"It's normal to have won prizes, no points and no energy, how can I communicate with you if I don't have energy?"

"Oh, how do you talk about how points are energy? Where are you technologically productive? What forces created the Mirror Space? Earth or aliens? ”

"If you want to trick me, no way! …… Secrecy! ”
