I plant a field in the last days

The words came out, everyone was staggered in place, Lu Yuan also hurriedly recalled his high school learned some general knowledge of physics and geography.

The reason why geothermal can be formed is that the groundwater in the magma layer or other areas with higher temperature is affected, the heat will be transmitted to the water source, and the water source is raised by the heat, and the formation of geothermal.

In the land of China, there are many areas with many natural geothermal hot springs, these places are invariably developed by those businessmen into tourist attractions, and these geothermal heat is used as a natural hot springs for tourists to use.

These hot springs contain a large number of minerals, people go to the hot springs for a long time, it will improve the body's immune system, replenish the body needs some minerals, although Lu Yuan felt that this is not very reliable, but this also shows that there must be water.

So Lu Yuan hurriedly beckoned, several people immediately gathered around, and then the map again opened to view the nearby water source marked, but there are several rivers made shadow is in the first year of the end of the world has been steamed dry, and the groundwater is also receded to hundreds of meters below, and even some places water has been directly cut off.

Although the third year of the end of the world sent a great flood, but because the topography of China is high in the west and low in the east, so that after the earthquake, these water sources and do not know where to flow.

Even if there is still groundwater, but the severe earthquake caused by the change in terrain, groundwater can not be inferred that there is no more, can only rely on artificial to detect.

Now to find an underground water, it is extremely difficult, even in the whole set of maps are not marked out which places of water can be used, although there are a few water sources exist, but this contains poison are marked, can not drink.

"Great! The water problem will be solved tomorrow, it's too hot here! We have to hurry back to rest and come back tomorrow!"

So Lu Yuan asked the people to mark this place down, stay in the future and then go back to continue the research, and at this time it was already late, the people out for a particularly long time, a long time to stay in this high temperature environment to go, people tend to dehydration and a variety of problems.

So for the sake of the safety of the team, Lu Yuan can only be stopped today's search.

Back to the camp, among Lu Yuan and the crowd will be radiation suit down, immediately, everyone's body are out of a heavy white mist, as if just came out of the sweat room, the clothes on the body are already wet.

After taking off his radiation suit, Lu Yuan felt exhausted and ready to go back to his place to change clothes.

But on the way is met Chen Yan, only to see Chen Yan is now carefully carrying a pot of utensils towards the direction of the laboratory, simply do not dare to pay too much attention to the people nearby.

After Lu Yuan saw it, he greeted from afar: "Yanzi, what is this thing you are holding?"

After hearing Lu Yuan's words, Chen Yan ah after the vessel in her hand almost fell to the ground because of unstable standing, but the good thing is that she finally stabilized her figure, and only after a long time slowly put the things on the ground, some Dian angrily looked back at Lu Yuan.

"You scared me to death, can't you see that I'm holding something in my hand? This is I got some aquatic plants from outside with great difficulty!"

Lu Yuan walked over, some curious to look at the glass bottle filled with water and plants.

"Aquatic plants? This thing is not all extinct? Where did you get this?"

Chen Yan's face instantly revealed a deep color of complacency.

"This is something that I've asked a lot of people to get, the people in the lab promised to help me get a little bit, but I didn't expect that it's been a few months since I finally got this little bit, it's precious!

"Oh, really!" Lu Yuan said this indifferently, in fact, just when he looked down he already knew that this aquatic plant is really the famous water hyacinth, also interspersed with some green floating duckweed.

These two plants are particularly precious after the end of the world, but before the end of the world, these two plants are everywhere, just find a small ditch to be able to find the existence of this plant, but because of the year-long drought, resulting in rivers have completely disappeared, basically all the aquatic plants have been extinct.

This time to see this freshwater water gourd and green floating duckweed again, Lu Yuan is still more or less surprised.

Seeing Lu Yuan said so indifferently, Chen Yan suddenly pretty face: "Lu Yuan, you look disdainful, do you know how valuable this thing is? Just this kind of thing a plant can be sold to tens of thousands of dollars ah, this is I found a lot of people to get a little, with this thing we can drink clean water in the future!"

Hearing this Lu Yuan was immediately shocked, and then hurriedly asked: "What? You mean this thing can purify water? I seem to have heard in the news reports before, this kind of thing seems to have caused pollution, how can it purify the water?"

Chen Yan mysteriously smiled, and then opened his mouth and continued: "This you do not understand it, the reason why the former will cause a large area of floating duckweed led to water micro-pollution, is because this thing absorbed a lot of chemical industrial products, and these chemical products contain a lot of nitrogen, phosphorus and potassium and other trace elements, resulting in their growth rate became extremely high.

So due to these aquatic plants on a large scale, resulting in the river was covered the entire surface of the water, and some underwater organisms do not get sunlight, can not photosynthesis to produce raised, resulting in the water below the oxygen content is not enough to cause pollution, if we control, this kind of thing can still absorb some debris and trace elements in the water! "

Lu Yuan nodded, he then understood why there are many people like to plant some water plants in their own fish tanks, not only for aesthetic purposes, but also to play a role in purifying water.

"Great, then it seems that our water problem can be solved, by the way, I want to ask whether those previously polluted water can use this plant to purify it?"

Chen Yan sighed: "In fact, the reason I got these two plants, is to study, to see if the water can be purified, but the people in the research institute for a long time have not been able to solve the problem, but I still do not want to give up, want to try again, if you can really fix the polluted water, then our water problem will no longer be a problem! become a problem!"

"Great, yes, can I pinch some? I also go back and try!" Lu Yuan reached out and pointed to the ground to put down that is a glass vessel tentatively asked a sentence.

Hearing Lu Yuan say to pinch a little, Chen Yan immediately like a baby clean hold up their glass bottle, shaking his head: "No, it is too small, if you study, I will not be enough, and this thing although it grows up very fast, but now this stage is very valuable, in case you give raise dead, can use a little less, and so on I'll give it to you after a few days of growth!"

"Don't, just give me a little pinch, I don't want more, just a little!"

Looking at Lu Yuan's eager look, Chen Yan finally could not help but laugh: "You ah, teasing you, how can I not give you it, although the price of this stuff is high, but for you, the big boss is still no problem, but now they are not willing to deal with us, so I can only get some from the old relationship through some old private, you can I'll give you a little!"

Lu Yuan hurriedly nodded his head and thanked: "Then thank you very much, let's hurry to your laboratory and get me some!"

From Chen Yan's laboratory, Lu Yuan can't wait to return to his place with his small plastic back, after closing the door, and then use his consciousness to put the water gourd and floating duckweed into the water pond in his dimensional space respectively.

Floating duckweed and water gourd into the subspace water pond the moment, immediately like a chemical reaction, the speed of change is extremely fast, in the form visible to the naked eye immediately began to grow up, not a short time to grow a large.

See the growth of a large area of water gourd and duckweed, Lu Yuan suddenly some panic, but the good thing is that there are a lot of fish and shrimp in the river are fond of eating some aquatic plants, see the emergence of new species, at once a few small fish and shrimp have pounced on the past, the duckweed and water gourd is a nibble, found that the taste seems to be okay ah, so attracted more fish and shrimp.

Lu Yuan suddenly a gun, he was afraid that his precious fish pond back to the water gourd and duckweed to death, if this is really the case, then it is really not worth the loss.

After the subspace in these water nourishment, water gourd and floating duckweed surface leaves look stronger than before, and the leaves are also much larger, the green concentration is also particularly bright, looks especially good.

Then Lu Yuan hurriedly took out a bunch of floating duckweed and water gourd from the space in a separate glass box, adding a little of the water in the secondary space.

The speed of growth of water hyacinth and water hyacinth has dropped immediately after leaving the subspace, but Lu Yuan knows that although it seems not much longer, but in fact, if you look carefully, the water hyacinth and water hyacinth is still much faster than using other water sources, mainly because of the reason of the water in the subspace pond and these water hyacinth and water hyacinth are grown in the subspace, but also slowly over time The growth rate will slowly decrease over time.

Looking at the water tank of duckweed and water gourd, Lu Yuan intends to give Chen Yan, after all, they now have a lot of equipment in the laboratory is not, only through some simple things to carry out experiments.

If you want to purify the water through aquatic plants, then the raw material problem is the big head, Chen Yan's laboratory of water gourds and duckweed is not enough for her to use, want to compare the experiment, it may have to wait a while, but now the water source in the mine is about to run out, if not solved, it is estimated that people may die because of lack of water.

Seeing that the water tank has been placed, Lu Yuan nodded in satisfaction, but this time directly to Chen Yan seems a bit inappropriate, after all, they only got these plants less than two hours, and at once returned to the other party so much, it is inevitable that Chen Yan will be suspicious.

......

The next morning, Lu Yuan directly dialed Chen Yan's phone, the other party received a call from Lu Yuan, learned to give himself something, immediately non-stop running towards Lu Yuan's residence.

When Chen Yan entered Lu Yuan's room again, a glance saw a glass jar placed on the desktop, which contains a jar of clear water, above a fish tank, and the fish tank inside this is exactly what they gave Lu Yuan yesterday water gourd and floating weed, only this amount seems a bit much.

"You ...... you these things from where to get? I just gave you only a little, does that mean you already have such things on your side? Then you gave me back yesterday ah! If I had known I would not have bothered to get it from the outside! Also owed a lot of favors!"

Lu Yuan smiled awkwardly: "To tell the truth, these waters are from the mine, which also has a very high radiation, but basically no great harm to the human body, this water has the advantage of containing a large number of catalysts, I gave you these things yesterday is to see if you can use as a catalyst for aquatic plants, I did not expect the effect is quite large! I didn't expect it to be very effective! So I called you early in the morning! Even if I just gave you some compensation for borrowing something, you go back and see if you can make something famous!"

"What? There is still water in the mine, really? How come I didn't find it?" Chen Yan looked at Lu Yuan with a slight trace of surprise and asked.

"Uh, of course there is, you probably did not notice it! Besides, this kind of thing is also particularly rare, and I worry that this thing is harmful to the human body, so have not said to outsiders, but now see your research seems to have encountered a bit of bottleneck, so this kind of thing out, I found this kind of thing as long as a little planted inside what things, basically the growth is particularly fast, you can go back to take a test! Right, this thing first do not tell others, save to the Institute that spread!"

Lu Yuan casually found a reason to muddle through, but Chen Yan is not a vegetarian, she is a professional researcher, but he is more interested in these floating duckweed at the moment, and did not ask anything more.

"Great, I'll take it back, thank you Lu Yuan!"

"Haha, you're welcome, we're both trying to stay alive!"

Watching the ecstatic Chen Yan leave his place with the big water jar, Lu Yuan nodded with satisfaction.
