"The year 4738 of the Yellow Emperor calendar?"

Chen Shi was stunned, but he breathed a sigh of relief, he actually used the traditional calendar Yellow Emperor calendar, and he thought at first that if it was other calendars, he might not know the specific time at all.

The Yellow Emperor calendar is much simpler, this is basically the well-known traditional calendar, and the conversion with the Western calendar is very simple, with the Yellow Emperor calendar subtract the Western calendar 2697 can know the current Western calendar.

So do the math, and learn that the production date of this food is 2041 in the Western calendar, which is indeed a future world relative to 2018.

But it should not be so easy to think that just because at the end of the Yuan Dynasty, history had changed, and the two worlds were in the same year, and technology, politics, and culture were very likely to develop to different degrees.

Knowing the specific year, but it didn't help him much, Chen Shi tore open the carton, and the biscuits inside had already become dry and crushed, such a carton could be stored for up to 6 months, and this result was not unexpected.

He threw away the cardboard box and chose to look for the plastic-wrapped food, but he soon became numb, and most of the plastic on the earth, which is buried in the soil, will not degrade for decades. And on the food shelves here, the so-called plastic products have disappeared without a trace, leaving only the remains of the food.

"This ...... Environmentally friendly natural degradation? ”

Chen Shi was shocked, well, the plastic used in food is environmentally friendly, but it is not a good thing for him, if only the polyethylene used like that oil drum would be good.

However, not all snacks are made of environmentally friendly and naturally degradable plastic, and he walked around the food area and found many beverage bottles, but they were made of glass.

It's a pity that no matter how tightly it is sealed, after decades of years, although the drink in the bottle will not volatilize, it has also had obvious precipitation, and Chen Shi did not dare to drink it.

Human food is not meant to be preserved for decades.

Similarly, Chen Shi opened a box of canned food, and through the gamma suit, he didn't find a foul smell, but saw some moldy spots.

The mood was very heavy, although before coming in, Chen Shi had a faint guess, but when the facts happened in front of him, he couldn't keep a complete calm.

“……”

After shopping in the food area, Chen Shi was too lazy to go to the seafood and meat area again, and there would be no good results anyway.

With such a heavy heart, Chen Shi returned to the atrium on the first floor along the way he came.

He thought about it for a while, and chose to go to the electrical and digital products area on the fifth floor, where he might find some clues.

A few minutes later, Chen Shi slowly came to the fifth floor.

The electrical and digital areas on the fifth floor are also mostly in the form of stores, and he went straight over, directly broke through the glass door, and stepped inside.

Looking around left and right, it seems to be some kind of store similar to a mobile phone, and the mobile phone is displayed in the counter...... I don't know if it should be described as a mobile phone, anyway, Chen Shi has never seen a soft and curved screen like this, which seems to be able to be worn on the wrist.

He picked it up and played with it for a while, but he didn't figure out how to turn it on, and of course it was most likely out of power and couldn't turn it on.

In addition, he also saw the folding screen, which together is a single piece, which can be increased by up to four times the size when opened, and it is super thin, and the four screens are only 5 mm when folded together.

I really don't know where the battery is.

And lots of cool-looking helmets and glasses?

I don't know if it's glasses, but they have frames, but they don't have lenses.

It's a pity that none of these seemingly extremely advanced digital products can be used, and no matter how advanced the civilian battery is, it is impossible to keep it for decades without using it and turn on it normally.

This result was not too surprising to Chen Shi, he walked out of the store and walked around other stores a few times, but he was shocked.

If the previous things have not exceeded his imagination, then the things sold in this store definitely make him very interested.

"Robots?"

Yes, it's robots for sale in this store!

He kicked through the glass door and walked in, and saw a robot placed at the door to be the same height as the person, the dusty robot had an obvious titanium alloy structure, and also had the same limbs and body as a human, which was completely a robot made by imitating the body structure of a human being.

But from the perspective of this robot itself, it is not the seventh-generation autonomous bionic biological robot of DJI Longge that Chen Shi saw in the Green Building Pavilion, not only is it not so advanced, but it does not build a layer of bionic skin according to human skin in appearance, but purely exposes the mechanical metal appearance.

Just in the position of its face, an unknown material was used, and a thing similar to a skin-colored mask was made, which looked like human facial features, but it still didn't look like it.

It's a bit dull.

At the back of the robot's head, there is a sophisticated mechanical structure, chips, and motherboards, which are covered with some kind of transparent hard plastic on the outside, and the inner layer is mechanically covered, which can not only protect the core structure inside, but also use plastic to prevent dust.

There are quite a few robots like this in this huge store, and there are more than a dozen of them standing on a huge counter alone.

In addition, there are robots in the form of animals, such as mechanical dogs and mechanical leopards.

No toy!

Chen Shi looked up at the wide electronic screen that was supposed to be an introduction, and he could also draw such a conclusion from these robots.

"Robots can be sold on a large scale...... It seems that the technology of this dislocated era is much more advanced than I imagined. ”

Chen Shi thoughtfully, let go of the palm that stroked these robots, and he suddenly thought, since it is a large-scale civilian sale of robots, will it solve a battery problem?

If civilian robots can't solve the problem of battery life, and they run out of power in two or three hours at every turn, it's too funny, and it is impossible to achieve large-scale sales.

Why do you have to be active for more than a day?

Even the battery that can be active for one day is too low, and a robot that can be active for at least three or four days is the ideal robot.

In any case, robots that have been active for a day can automatically go back to recharge, so will such batteries allow these robots to have the power to start and turn on decades later?

Chen Shi thought the idea was not bad, and the only problem was...... How did Nima's robots turn on?

Where's the button to turn it on?

He searched for a long time, but he couldn't find the switch, and even when he had an idea, he went to a certain unspeakable part to check it, but still didn't find any switch.

Dumbfounded, these robots can't be wirelessly started and activated, right?

In that case, then there is nothing he can do.
