I'm sorry.,Just finished writing.,Headache.,This chapter is a little tangled.,The biggest part of the change in the original setting.,Yesterday I saw it.,If it's really written according to the setting.,I'm afraid a lot of people will be around it.,No matter how you write it, you're not satisfied.,So I overhauled the setting.。

As soon as Xu Yi stood firmly, he saw the two little foxes raise their heads as if they were aware of it, twitch their noses twice, turn around and run towards him, squatting on the ground and staring at the box in Xu Yi's hand.

"Damn, you're eating from the bowl and looking at the pot. Xu Yi scolded with a smile, put the box down, and grabbed two handfuls of cherries from the box that was ready to eat by himself and put them in the food box.

The two little foxes let out a short cry of excitement and turned back to eat.

Xu Yi glanced at the two small things, piled the boxes on the table, then thought for a while, then took his bag, and then rummaged through his desk, found some things, and entered the space again.

On the one hand, there are some real yàn that can be done, and on the other hand, the electronic scale is still in the space.

Xu Yi didn't dare to put this thing in the space overnight, especially if this thing was placed on the edge of the water without protection, and if the water vapor went in, it would break down after a long time.

I'm going to the hospital tomorrow morning, and it's not necessarily whether I can have time to go to the flower and bird market this afternoon, and if I have to go back the day after tomorrow, in the space, it's almost two months past.

Xu Yi checked on the Internet with his mobile phone, and the cherries only took about two months at most from flowering to ripening.

After such a long time, who can guarantee that this scale will not be damaged, this is more than a thousand yuan.

Xu Yi put the bag down, and then pulled out a broken earphone with only one earbud left from the bag.

Then Xu Yi carried the earphone cable in his hand, let the thing hang down, and slowly turned around in place, seeing that this thing did not suddenly fly up or pull it in which direction, he took back the earphone head, and cut off the earphone cable soldered on it, leaving only the earphone head in his hand.

Xu Yi pinched the earphone head with one hand, and with the other hand, he broke off the glued plastic cover on the earbuds, and then used two fingers to pull out the sound generating unit inside.

Throw all the bits and pieces back in your bag, leaving only the sound generator in your hand.

The sound generator is nothing more than a hollow round piece of iron with a small round piece of plastic film embedded in the middle, and the center of the plastic sheet is also glued to a coil on the back.

The round iron sheet is also fixed to a small black circle at the back, about the size of a fingernail.

This circle is actually a magnet, and the coil behind the plastic sheet is worn through the round hole of this magnet.

When there is a current in the coil, it will move in the magnetic field and change the tension of the plastic film in front of it, so that the electrical energy can be converted into sound, in fact, this is also the simplest sound principle of the speaker.

Xu Yi took this out, in fact, what he wanted was just the magnet inside, but this magnet was glued to the iron piece, and it was difficult to take it down alone, and the iron piece did not affect Xu Yi, so they were left on it.

Then Xu Yi took out the sewing box from the bag, took out a sewing needle, turned the magnet side up, and grinded it a few times with the tip of the needle to magnetize it.

Xu Yi carefully took a thin line and hung it up to make a simplest compass - of course, Xu Yi didn't know which pole the needle tip was magnetized into, so he had to wait for the real yàn to finish and go out and make it real.

Xu Yi carried the shovel, then put down the needle in his hand, and let it rotate freely in mid-air, and then found that after the needle rotated a few times, the tip of the needle pointed in a direction when it stopped, and Xu Yi drew a circle around himself with his foot on the ground.

Xu Yi twisted the thread on his hand a few more times with his fingers, and saw that the needle below had turned two more times, and Xu Yi found that when the needle was still, it was still pointing in the same direction.

Then, Xu Yi followed the direction of the needle tip all the way forward, until he walked to the edge of the light mask, and then inserted the shovel into the ground casually, and then retreated to the place where he drew a circle, walked a few steps to the side, and then repeated the previous process, but just raised the height of the needle in front of him.

Then he squinted his eyes along the long axis of the needle and looked forward, and after that, Xu Yi found that although the position of the needle was not directly facing the shovel, it was also a few steps away from the shovel.

Xu Yi changed a few more places and repeated the process in the same way, and the results obtained were always about the same, presumably the magnetic field lines in this space were parallel.

Of course, in order to be more accurate, Xu Yi changed a needle, and then took the tip of the needle and grinded it a few times on the iron sheet on the other side of the magnet, and then did the same real yàn, and found that there was no difference at all except that the tip of the needle was opposite.

Xu Yi nodded, it seems that there is still a relatively weak magnetic field in this space, Xu Yi put his mind at ease, although the strength of this magnetic field is not known, but this is definitely not very strong, such a magnetic field strength is absolutely not harmful to the human body.

The reason why he did this was actually that Xu Yi was not sure whether the change in the magnetic field would have any effect on animals and plants, and he was still thinking about buying some bees.

If in an environment with no magnetic field at all, who knows if the bee will get lost because there is no magnetic field or something, although I want to do research to say that the bee relies on polarized light and fragrance to identify the direction, but who can guarantee that they really don't need the help of the magnetic field?

Carefully pinning the two needles to the pocket of his shirt, Xu Yi dug a small shallow line on both sides of the "bathtub" in these two directions through the center of the "bathtub".

Xu Yi then took out a voice recorder that he had used for several years, and after seeing that the battery was sufficient, Xu Yi selected the FM radio function on the main menu.

Xu Yi put on the headphones, took the voice recorder and turned on the automatic search function, and then listened carefully to the sound in the headphones, but when the search was completed, the voice recorder did not find any radio signal.

After repeated attempts to determine that it was fruitless, Xu Yi adjusted the recorder to the mid-wave band again, and also operated it again, but the result was also fruitless.

After trying, Xu Yi judged that there were no radio signals in the amplitude modulation band and frequency modulation band in this space.

As for other wavelengths, Xu Yi can't detect them for the time being, of course, it also proves that the radio signals in the real world are shielded in this space, although there are fewer and fewer people listening to radio in this era, but at this point, there are still a lot of radio stations playing programs, if it is not blocked, how many should always be able to listen to a few stations.

After checking this, Xu Yi turned off the recorder and took out a small calculator that he bought in statistics class, and there was a small row of solar panels next to the display screen of this calculator, which could make the calculator not have to consume the backup battery inside in the light.

However, I haven't used this for two years, and Xu Yi doesn't know if it's good or not, so Xu Yi directly opened it and tested it.

Fortunately, although the screen is a little aging and a little blurry, it can still be used normally.

However, Xu Yi is also worried about whether the solar cells on this calculator are still useful, and if this is finished, it will not work, so he has to buy another one.

After all, I was in the room before I only thought about everything I wanted and put it in my bag, and I didn't even think to check it again.

Xu Yi turned off the power switch, flipped the calculator over, opened the back compartment door, removed the button battery inside, covered the lid, turned the calculator back, and clicked the switch on the top.

Suddenly, the screen lights up again, and it seems that the light function here is the same as that of the outside world, otherwise this battery will not work......

But then Xu Yi patted his head, thinking about it, if it doesn't work, what does the plant rely on to grow!

Of course, Xu Yi has no way to judge what the components of this white light are, and it is estimated that he has to find some equipment to distinguish them.

Although a basin and a mirror can decompose the sun's rays, Xu Yi is not clear whether this light source can work, is it necessary to make a dark box and make the surface light source a point light source?

Xu Yi raised his wrist, and then shrugged his shoulders, he didn't bring his watch in, but if he really brought this watch in, it would be very troublesome, and he would have to readjust the time when he went out.

Or the next time you go out, you'll have to get an electronic perpetual calendar to record the time here separately.

Then, Xu Yi thought, next time, should we buy a mechanical wall clock together, adjust the time in the outside world, and then bring it to this, and then see if there is any difference in the time calculated by the two, so that we can compare the difference in gravity between the inside and outside of this space.

After all, there is a lack of professional equipment and equipment, and there is only so much that can be measured, so pack up the things, and then put the counters from the last time into the bag, and Xu Yi is ready to go out.

However, he wanted to pick up the electronic scale with his bag on his back, remembering what happened before, Xu Yi thought about it, and then used the bottle that poured the cherry tree last time to fill most of the bottle with soil, and then carefully wiped the soil outside the bottle, remembered the volume of the soil, and then put the bottle on the electronic scale to weigh, and after remembering the value, he put it in the backpack.

Xu Yi filled the basin with a water cup for half a basin of water, and after checking that there was nothing on the outside of the basin, he also put the basin on the electronic scale to weigh it, and then took everything out of the space.

Out of the space, Xu Yi directly placed the scale on the flat ground with the basin above, and then waited for the water to stand still, then turned on the electronic scale again, and then looked at the changes in the numbers on it, and found that after waiting for a few minutes, the value on the scale was always exactly the same as when it was in the space, and it seemed that the water seemed to have no signs of changing.

Then, Xu Yi took out the bottle in the bag again and put it on the scale, until the soil in the bottle finally turned into water, and the value did not change at all.

This also proves that the weight of things in space does not change when they are outside, and it also proves that the density of earth and water in this space is also equal.
