Back at home, Xu Yi cooked rice, and then went to fill the little fox with some cherries to eat, and then turned on the flashlight function of the mobile phone and watered the transplanted greens and chicken hairy vegetables.

There is no shortage of water, so there are not many dead vegetables, Xu Yi is going to get up early tomorrow morning to make up for the seedlings again, and as for the lack of them after making up, he doesn't plan to care about it anymore.

However, tomorrow is also the last day of May Day holiday, Xu Yi called the boss before, and he said that several people are ready to come back today.

As for Xu Yi himself, he naturally needs to go back to the dormitory, after all, he hasn't seen him for a few months, he actually misses these people, and he raised a fox in the house a few days ago, although it doesn't taste good, but he always has to lose some hair or something, so it's better to go back and clean it up first.

Several people in the dormitory are wolves, plus the third child has a girlfriend, and he has to take out at least two boxes of cherries to be able to eat it, of course, the origin of this cherry can only be said to be bought by himself.

After pouring the dishes, Xu Yi simply ate something, rested for a while, and then entered the space.

There was no operating table, Xu Yi went out of the space again, went directly to the study and put the tables and chairs inside into the space, and then opened the carton containing the machine qì, and assembled the machine qì inside In order to avoid polluting the sample, Xu Yi connected the machine qì to the inverter, turned on the spectrometer to warm up, and once again put on a new pair of disposable gloves, used a small measuring cup to collect water samples from the "bathtub", carefully poured it into the liquid sample room, and then took the protective mask and buckled it on his face.

If all the ingredients in the water sample exceeded the standard, it would not surprise Xu Yi so much.

No matter how Xu Yi adjusts the inspection conditions, the results obtained are the same, the same as the report issued by the previous inspection center: this water has no impurities at all, it is completely pure pure water, except for hydrogen and oxygen, there are no other impurities at all, and the results analyzed by the system automatically call the number of jù libraries are also pure water, which is exactly the same as the test results obtained by the inspection center.

How can this be water, how can it be pure water? how can water behave like this, and how can we explain the problem of the bee's corpse?

Thinking like this, Xu Yi went to the colorful cloth and took all the bee corpses, put them on the table, took one from it and threw it into the "bathtub".

The scene where the corpse was dissolved and disappeared appeared again, and Xu Yi collected another water sample, but no other elements or substances were detected in the water, which was still a pool of pure water.

Nothing was found in the water at all, and when a leaf was plucked and thrown into the water, the leaf disappeared as well, and disappeared faster than the bee's corpse, and the results of the re-examination remained unchanged.

After Xu Yi took the measuring cup and filled it with water, whether it was a bee corpse or a leaf, there was no trace of dissolution at all, obviously, this function only existed in the "bathtub".

Thinking of the disappearance of petals and leaves before, Xu Yi couldn't help but be a little suspicious, could it be that this soil also has such an ability?

Thinking like this, Xu Yi took another bee and threw it on the ground.

Sure enough, the corpse of the bee also slowly disappeared after touching the ground, Xu Yi picked up the rest when the corpse disappeared halfway, and even could see that half of the corpse in contact with the ground clearly showed the appearance of the internal organs of the bee, if it wasn't for seeing it with his own eyes and the unevenness on the profile, Xu Yi would even wonder if this was a prank, holding this bee specimen and placing it on the ground, and the bee did not change in the slightest in Xu Yi's hands, Xu Yi put it on the table for a while, and did not see any change in this thing, obviously, the air in this space does not seem to have this dissolving ability。

It seems that this water dissolves plants and animals, and the ground is also fully equipped, and this must be a problem that is difficult for science to explain, and this question can only be put aside for the time being.

After all, there is still air and soil that need to be tested, and hopefully no harmful substances will be detected in it.

Xu Yi suppressed the excitement before he was about to know the result, took a shovel and dug down on the ground next to him, then changed his gloves, grabbed the soil under the pit and put it into the solid sample room, and then turned on the test again.

After all, normal soil is composed of organic matter and inorganic matter, and the composition is quite complex, Xu Yi has been mentally prepared, and wants to make a death break with this result, after all, at least dozens or hundreds of elements need to be compared and analyzed, which is not at all something that a person who has only received a few days of training can analyze.

It's just that after the results came out, Xu Yi was stunned when he looked at the pattern with only two spectral lines, could it be that he didn't dry the water and covered up the test results of other elements, it doesn't seem to be like this, right?

Thinking like this, Xu Yi found a piece of wire to come out, simply folded a shelf, put the small measuring cup on the edge of the "bathtub", filled the beaker with some soil, and then found a candle, carefully moving slowly on the bottom of the beaker, so that the water in the soil in the beaker evaporated.

Half of the candles were burned out, and the soil in the beaker had long since stopped steaming, and there was even a faint burning sensation emanating from the measuring cup.

After waiting for the soil samples to cool down, Xu Yi took some soil samples and put them in the sample room.

It's just that the results after the test made Xu Yi stunned again - the result shown by this soil sample is still only one substance - water!

This soil is all water?

I'm afraid that this is more water than the familiar classic poem "The sea, it's full of water!", which makes Xu Yi feel incredible.

Xu Yi has also seen flowers planted in water, waiting for them to take root and then transplanting them into the soil, but if they are not transplanted for a long time and only hydroponics, then they must add nutrients to the water.

Otherwise, even the bulb flowers such as narcissus or hyacinth, which are sold in the market in winter, are just placed in the water, waiting for the flowers to bloom, and the nutrients in the bulbs are not enough to support the growth of the flowers.

The basis of life is "sunlight, air and water", but soil is also indispensable for the growth of most plants, and the colorful soil provides plants with various minerals and various soluble vitamins or organic matter during the growth of plants.

If there is only sunlight, air and water, I am afraid that the vast majority of plants will not be able to survive at all.

Therefore, "sunlight, air and water" are at best a necessary condition for the vast majority of living things, and they are not sufficient conditions at all.

Even in the vicinity of deep-sea craters, there are ecosystems that rely on sulfur as an intermediate body for energy transport, even if they do not rely on sunlight, and this does not require sunlight at all.

Iron is an important part of the body's red blood cells, sodium and potassium are the necessary basis for energy transport and action, as far as chlorophyll is concerned, an element that must be present in the purine ring is magnesium, and this can only be obtained from the soil through the root system, if there is no magnesium element, then there is no green leaf at all and there is no photosynthesis, where does this come from?

Although Xu Yi felt incredible, he was still seriously analyzing, could it be that this spectrometer was broken?

Xu Yi picked another leaf from the tree and threw it into the sampling room, but it took more than ten or twenty seconds for the result to make Xu Yi breathe a sigh of relief.

In addition to hydrocarbon, hydrogen and oxygen, dozens of elements such as nitrogen, sodium, potassium, and magnesium were also detected, while those elements that are not needed for plant growth or even harmful are not detected at all.

In the end, Xu Yi used the gas sample chamber to collect air and prepare to test the gas in it, but it was also ridiculous that only hydrogen and oxygen were detected, but in addition to the extremely trace carbon element, there was also less nitrogen element, and the nitrogen gas, which is the most expensive in the earth's atmosphere, has not been found at all.

Xu Yi can naturally analyze that these very trace elements should come from the rich floral fragrance in the air, and these low-molecular esters and heterocyclic components are the essence of this floral fragrance.

It's just that there is completely free oxygen in the air, which makes Xu Yi really can't believe it, this "air" with no oxygen and only water vapor is afraid that if you let a fish in, you will have to suffocate, but you are alive and kicking in it, not only does you not feel stuffy, but you feel comfortable, how is this possible?

Xu Yi thought for a while, felt clueless, and turned around and walked out of the space.

Since the inside of this space is unreliable, it's always okay to bring something in from the outside.

Xu Yi went out to the vegetable garden and plucked a large handful of chicken hairy vegetables, then entered the space, collected some soil from the vegetable roots and put them into the machine.

Sure enough, this is the soil, in addition to a large amount of carbon, nitrogen and oxygen, there are also dozens of elements, such as the most composed of soil

Xu Yi pulled a small piece from the chicken hairy cabbage and put it into the sampling room for testing, only to see that there were even very small amounts of lead and mercury that are harmful to plants.

Xu Yi thought about it, took a few chicken hair vegetables and planted them on the ground, and then scooped up the water and poured them, only to see that the chicken hair vegetables were growing rapidly, but after a while, a vegetable sprout more than one meter high would grow, and small light yellow flowers bloomed on it, and the unique fragrance soon attracted several bees to come and collect pollen and nectar.

Xu Yi took a small leaf to test, but found that other beneficial elements not only did not decrease, but increased slightly, and the content of those lead or mercury decreased significantly, obviously, in this space did not continue to suffer from the pollution of these elements, so as the plant grows, this concentration is also decreasing.

Where do these elements come from?

Suddenly, Xu Yi suddenly remembered the two lines of small characters written on the back of the jade plaque, "But if you ask for something, you must respond to it." ”

Could it be that these two lines of text say this?
