Chapter 217: Gold-Absorbing Plants

……

Almost instantly, Rayong's figure disappeared from the deck.

The next moment, the figure in the monitoring room flashed, and Rayong walked in quickly, and before the person arrived, a few questions had already blurted out: "Where is the rain?" Is there a holographic projection? How much rainfall? ”

"Master~!" Xiao Luo turned around and saw Luo Yong, her face couldn't help but show a surprised expression, and then she quickly pulled over a surveillance image on the virtual display screen in front of her and opened it for Luo Yong to see.

Rayong glanced at it and saw a scene that surprised him.

In the surveillance image, strands of rain like hairs fell in the air, sweeping over the lime clouds as much as possible, but suddenly disappeared when they fell less than 100 meters and evaporated into water vapor again.

This kind of rain may not achieve the purpose of moistening the earth's surface, but it really reflects the results of Rayong's efforts. This at least shows that the temperature in the sky has dropped to achieve the purpose of condensing water vapor into water droplets.

And with liquid water, the basic conditions for plant growth have ~ the first step of planetary transformation, which can be regarded as a complete success!

"Xiaoluo, re-sample the air and test the ratio of carbon dioxide and oxygen in the air."

After Luo Yong finished instructing Xiao Luo, he raised his hand, summoned Xiao Cui in the form of Lori, and said to her: "Xiao Cui, monitor the surface temperature, and then tell me where the temperature is lowest and where the most stable position of the earth's crust is." ”

Rayong waited for the results to come back while pacing anxiously around the surveillance room. His heart was restless at the moment, but his eyes were surprisingly bright, and his mind was turning over and over again. It's all a second-step plan.

"The hosts. The magma crust here has been initially cooled. The temperature is initially estimated to be within 200 degrees Celsius, which is the weakest place in the crust of the entire planet. Xiao Cui was the first to come up with the results, pulling out a map of the planet's surface from the monitoring data.

Rayong took a look, and sure enough, he found a darker area in the picture, which was lower than the obvious temperature around it.

This place is in a special location, just in the center of three fixed volcanic eruption sites, and the crustal situation is the most stable. A large volcanic ash plain has also been formed, which can be used as a base for the second step of the experiment.

"Xiaocui, select plants that are resistant to high temperatures and have the ability to absorb and purify metals, and all varieties are listed."

Rayong turned around and paced two steps, betting on Xiaocui's order again. However, before Xiao Cui succeeded, Xiao Luo suddenly walked in.

"Master, the test results are out, and the current carbon dioxide content in the air is 19%. The oxygen content is 1.001%, an increase of 1% from the previous period. ”

"Good!" Rayong was very pleased. Not much has changed, though. But now it's only been two months, and a 1% change in two months is already very powerful. With the passage of time, sooner or later, the air content here will be the same as or even surpass that of the earth's civilization.

Although those advanced civilizations have also transformed the planet into an ecological planet, after all, it is time-consuming and labor-intensive, and it is not a hundred and eighty years before it can be successful. Rayong is like this now, and it can be regarded as a rapid progress~

Combined with the ground plants, I am afraid that the rate of oxygen increase will be a little faster. However, the volcanic ash clouds in the sky are so annoying that they block a lot of sunlight, and the ground plants may not be as pleasant as the floating flowers.

Rayong thought about it for a while, and simply transferred two specially purchased spaceships to sweep back and forth like vacuum cleaners every day, trying to clean up the ash cloud as much as possible. These cleaned ash clouds, after precipitation, can also be placed in the culture tank as a seedling substrate.

At this time, Xiaocui also screened out eighteen kinds of plants, including five kinds of vines, three kinds of algae plants, one bryophyte, six kinds of small shrubs, and three kinds of annual herbaceous plants.

The characteristics of these plants are different, and the high temperature ability and the types of metals that can be absorbed are also different, and after seeing it, Rayong simply made a sample of all the plants with a stroke of his pen, and prepared to simply conduct a comparative experiment to select the most suitable plants for large-scale planting.

At this time, Xiao Cui, who had not received an order for the time being, finally found Luo Yong uncontrollably and asked, "Master, what are you doing with these plants?" ”

Luo Yong was in a good mood at the moment, and when he heard this, the corners of his mouth curled, so he kindly explained: "The mineral content on the EX-05 star is very rich, but it is not easy to mine because of the mixed quality. These plants do not have these concerns, they only absorb the metals they need, and the metals extracted from these plants are inherently of excellent quality, which is much more cost-effective than mechanical mining. ”

"Moreover, after the metal in the volcanic rock and volcanic ash is extracted, the remaining part is mixed with plant ash, which is the natural soil, which just solves the problem of no soil on the planet."

Xiao Cui blinked, tilted her head as if she understood whether she understood or not, and after a long time, she held back a sentence: "Master, is this what you said 'killing two birds with one stone'?" ”

"Hmm." Rayong couldn't help but laugh.

Xiao Luo didn't know when she went out, but she just came back at this time, and she was still holding a tray in her hand, and a cup of tea in the tray was exuding a curling fragrance.

"Master, you've been busy all day, let's have a cup of tea and rest~"

Xiao Luo put down the tray, took the teacup and handed it to Luo Yong, then grabbed Xiao Cui, and said with a smile: "Xiao Cui, are you messing with the master again?" ”

"Where? Sister Xiaoluo, I'm obviously very well-behaved today. Don't believe you ask the master! Xiao Cui pouted and writhed in Xiao Luo's arms, her face full of grievances.

Luo Yong watched the two of them make a fuss, and couldn't help but relax a little, smiled and took a sip of tea, the temperature of the tea was just right, obviously the result of Xiao Luo's deliberate control.

The abundant aura mixed with the fragrance of tea flowed into his mouth, tossing and turning between his lips and teeth, making Luo Yong's mind suddenly clear, and his originally slightly tired spirit was instantly invigorated.

It is worthy of the famous "Qingyun Ling Tea" in the interstellar world, and the taste is really extraordinary.

After playing with Xiao Cui, Xiao Luo straightened her clothes and said to Luo Yong: "Master, the seeds of the eighteen kinds of plants have been put into the cultivation room, I will go to help you sort out the cultivation tank first, and after you finish drinking tea, you can start to light it directly." ”

"Let's go~" Rayong smiled, very satisfied with Xiao Luo's thoughtfulness.

Xiao Luo smiled softly, turned around and walked out of the monitoring room, and the long curved skirt dragged to the ground, lining her figure extremely graceful.

Looking at Xiao Luo's distant back, Luo Yong's hand holding tea paused slightly, and a trace of complicated emotions flashed in his eyes.

These plants are becoming more and more human, and perhaps, it is time for him to give them a proper name.

……

"How are these plants growing?" Rayong stepped into the cultivation room and looked at Xiao Luo, who was busy in front of the cultivation tank.

"Master, you're here~" Xiao Luo turned around and smiled, then called up the data records of the cultivation room, and introduced, "These eighteen species of plants are growing well, but one of the mosses and a type of algae is particularly prominent. ”

Xiao Luo pointed to one of the rows of data and said, "Look at this...... During its growth, it absorbs a rare metal. Reserves of this metal are extremely scarce throughout the interstellar range. Although the reserves of EX-05 are not very large, this scarce variety, even if it only appears a little bit, will be robbed like crazy~"

"Nine Yi Essence Gold?"

This name was unheard of, and Luo Yong was puzzled, so he called up the details, but when he saw it, he was stunned. Isn't this a meteorite?

Well, it's just that the name is different, this situation is too common in the interstellar ~ Anyway, this thing is a necessary material for refining high-end magic weapons, and it is indeed very precious~

"There is also this kind of Huanyang algae, not to mention the fast reproduction rate, but also the ability to refine the most abundant reserves of Yi iron ore, if planted on a large scale, the yield will be considerable."

After Xiao Luo finished the introduction, she raised her head and stared at Luo Yong with a pair of dark eyes, as if she was waiting for him to make a judgment.

Luo Yong thought for a moment, and then went through the situation of the other sixteen plants, and then nodded, affirming the results of Xiao Luo's work: "It's done well." You are meticulous, go back and draw up a plan for me directly, if there is no problem, the plan will come according to this. ”

"Yes. Master. ”

Luo Yong turned around and was about to leave, but Xiao Luo suddenly stopped him. Rayong paused and leaned over to listen to her.

"Master, I just heard Xiao Cui mention that the three volcanoes around the plain I chose seem to be erupting again, and I'm worried that it will affect this plan."

Luo Yong nodded, indicating that he knew, and then turned to the monitoring room and reviewed the monitoring data in the last half hour. After some analysis, Luo Yong found that Xiao Luo's worries were not unreasonable.

Although geographically speaking, the eruptions of the three volcanoes do not affect the central plain, but the volcanic ash ejected during the eruption and the heat from the magma will cause the temperature of the plain to rise suddenly, which is likely to cause the newly planted plants to be unable to adapt, causing widespread death.

This cannot be left unguarded.

However, it is too troublesome to change the plant species now, and there may not be a suitable species. But if you don't change the place and don't change the plants, you can only find a way to stop the eruption~

The question is, where is it so easy to stop a volcanic eruption?

"Actually...... It's not impossible to ......" happened to be in charge of the Yan Shot in the monitoring room, and when he heard Luo Yong's self-talk, he frowned, and his face was slightly solemn.

Hearing Yan Shot say this, a vague thought seemed to appear in Luo Yong's mind, but he didn't understand it for a while, so he asked, "What do you say?" ”

"There are several kinds of fire-based spirit plants that can take root in magma, such as fire scale fruit, lava fruit, vermilion fruit, and ...... Liuyanhua."

"Stop!" Luo Yong instantly felt that his head was swollen, and hurriedly stopped Yan Jian from continuing.

The first two are just that, but it's still a bit possible. So what are Zhu Guo and Liuyanhua? It was the treasure of heaven and earth in ancient legends, where could he get it?

However, this is an idea, and it may work.
