Second-order minerals are a division of purified minerals, and they were taught by Han Zhen after Mengkong's study. If the best refined minerals in Sig are designated as third-level or fourth-level, most of the second-level countries are produced in second-level countries. In the past, the minerals extracted from the earth civilization had no grade and could only be considered crude minerals. The price was sold at a cheap price. Because of this reason, only after being bought by the Tiandun family and then refined again can it be considered first-level minerals.

The higher the civilization, the higher the requirements for mineral level, and purification is a very necessary process. Take the gold in the original earth civilization for example. The gold of the three nines is already extremely pure, but in some third-level civilizations, some manufacturing industries that require gold, are far from enough. There are too many impurities, and they can purify to at least four nines, five nines, or even six nines. In countries like West that are about to enter the fifth-level civilization, the requirements will be higher when using gold, and reaching nine nines is a necessary condition. The extremely purity gold must be decomposed and decomposed into single substances.

The term single substance is inaccessible to the point of view of civilization without reaching the high-end. In the eyes of original earthlings, gold, which is extremely stable and has extremely high purity, is a combination of multiple metals with similar attributes, named composite substances, and gold is called composite gold; decomposing into single substances means decomposing and flying out of composite gold. Single substances can be used alone according to the different uses, or several of them can be combined and used. The methods are diverse. The improved substances obtained through such processing will be stronger than the previous substances.

This is just one of the points. The degree of improvement of the original composite substance is not too great. Now, the era of technology in using single composite substances has passed. A truly high-end civilization has long begun to try to dissolve and fuse single substances and other substances to form new composite substances, and has achieved great sweetness. Therefore, at the level of level 5 civilization, it is clear to a country's civilization level by looking at the means of decomposing composite substances. The higher the country, the more single substances it decomposes, the more new composite substances combined, and the better the effect.

"Its body can reach the second-level purification?!" Han Zhen was a little surprised. It was very good! When Star Tree No. 45 dies, all branches and rhizomes will be in this way, how much trouble can be saved at that time! It's just killing two birds with one stone. But after thinking for a while, I frowned again, so it shouldn't be? I predicted before I left, and it would be extraordinary to reach the first-level! "How did you do it?"

"Master, it can indeed be achieved!" Yang Yichen said. It was also shocking for him, the experimenter, to get such results. "I didn't expect this to happen at that time, but later I found the reason, which has a lot to do with the material composition of the planet 2 where it is located." While speaking, the material composition of the planet 2 was adjusted out and enlarged.

"Damn it, you're lazy!" Han Zhen cursed. This planet No. 2 was probably a meteorite that had been wandering in the universe for a long time. After arriving here, it was left by stars. The iron, copper and silver on it are its basic components, and it is everywhere! There is no soil, even stones, and the proportion is pitiful - under such generous conditions, it's really a pity for people to not reach the second level!

Yang Yichen scratched his head embarrassedly.

"Which kind do you use to conduct experiments on the Spirit Devour ore?"

"Master, we first use unrefined ore to experiment, and then directly deploy the minerals after the resultant. After many times, we also use the second-order ore to be weighed, the third-order ore after weighing, and the fourth-order after weighing... Except for the ore that is not recorded due to errors, the others can reach one thousandth of the thousandth." Yang Yichen answered confidently.

"First level?" Han Zhen asked gently knocking on the table.

"Yes, Master, the minerals stripped from the fruits are all first-level." Yang Yichen understood what Master was most concerned about, the level of minerals in the fruits produced by the star tree.

The first-order is actually very good. Even if it is just a rough ore, Han Zhen felt that he should be satisfied. After all, it was just a fruit, and it was of the same nature as the ore that the miner had just dug out. The biggest function of the star tree is to aggregate all the minerals distributed everywhere without missing a trace. As long as there is a first-order purity, the next thing will become very simple.

Star Tree No. 45 is the most representative of Yang Yichen. He has been responsible for the development of sixteen star trees, and the others have been explained to Han Zhen one by one. He is also responsible for the star tree No. 46, and is also generated in water and sunlight like No. 45, but No. 46 is more relaxed in nutrients and can absorb 72 minerals. It is a leap forward to be able to contain fruits of two minerals.

"Yukun, what are you doing?" Han Zhen asked.

"Master, I have fifteen kinds of people responsible for it. The name is from No. 16 to No. 30..." Liu Yukun took out his achievements over the past year and said in detail, "...This is the Star Tree No. 30 I developed. It abandons height and strength and absorbs the characteristics of crawling grass and dead tail. Master, please see, this is my external test site."

In the entire square kilometer area, all of them are black and white dots, and they are covered with tight and solid. Liu Yukun adjusted the hologram screen and showed the situation under the surface: the bottom of these grass objects has dozens of thick roots, with a diameter of more than fifty meters! The length is about two thousand meters. The fibrous roots diffracted from this thick root are even more difficult to see clearly, and they lingeredly wrapped all the soil between the surface and the two thousand meters underground!

"No way, this place is full of his nutrients, right?" Han Zhen asked jokingly, making Yang Yichen blush at it.

"No, Master, I am different from my sixth brother's test site. Soil and rocks account for more than 90%. Only a small amount of metal ore can provide some necessary nutrients. When there is insufficient nutrient, he can transform it and absorb conventional nutrients in the soil for self-use... Because it abandons height and strength, it will minimize its demand. Because the crawling grass has super reproductive ability, it has only been half a year since it planted the Star Tree No. 30 and has entered the maturity stage. I have made strict regulations on the limitations, that is, it can only reproduce within 500 meters of the main root, so that it has not spread too much."

Han Zhen nodded. Any plant, especially those with strong reproductive abilities, must be controlled. He is very clear about the consequences of not implementing reproductive restrictions. The optimized plants are too perverted, and it will definitely be a disaster after being spread!

Liu Yukun continued: "The characteristic of the slaughtered tail is that while we harvest the two precious ore fruits, we can also extract liquefied ore liquid from the main roots, and the interval is two months;..."

They are all talented! Listening to the report of the two, Han Zhen sighed in his heart that he was so satisfied with his two apprentices. It was only a year, and if he had given a few more years, he might have created a plant that could directly penetrate into the heart of the planet to extract the core magma!

Tan Gongyan was one of the first outstanding agricultural scientists to follow Han Zhen. His level was definitely enough at that time. However, because of the rapid development of the Han family over the years, especially the rapid development of the Chinese people, there were more people who were capable than him. For example, Liu Yukun and Yang Yichen, they would not talk about how much help they had in their research. They were the brain domain that changed after practicing the mind method. When receiving new knowledge and new technologies, they were much stronger than Tan Gongyan.

Han Zhen did not forget the contributions of these old guys. First, he popularized the Diyuan mental method among every researcher. A hero like Tan Gongyan not only enjoyed the gene modification liquid, but also wanted his earliest eight disciples with extremely advanced skills, and taught Tan Gongyan and their first three levels of Tianyuan mental method in total twelve levels. As long as they can practice these three levels, not only will their lives grow greatly, but they will also be more powerful in their research.

Although Tan Gongyan is not as good as Han Zhen’s two apprentices in R&D capabilities, his qualifications are there and he can better coordinate the cooperation between researchers. Han Zhen’s request to be the dean is considered to be the best use of the goods.

"Old Tan, you should be responsible for these top fifteen types, right?" Han Zhen asked with a smile. Only one-tenth of the researchers assigned by the two apprentices in the research institute. The others were given to Tan Gongyan. There were many people and great strength, and they also slightly supplemented the lack of ability. Han Zhen personally asked about these, so he naturally knew.

"Yes, lord, Xiao Liu and Xiao Yang are considerate of me, and handed over the simplest fifteen items to me." Tan Gongyan was very modest. The fifteen types he was responsible for were carried out in the breeding dish inside the base, because his star tree species are only suitable for use on administrative planets.

The nature of Tan Gongyan's research determines that protecting the environment is regarded as the top priority, so it must be conventional in terms of nutrient requirements, which is easy to do; it must also have some purification functions, and also include the characteristics of purified plants developed in the past; it cannot be too aggressive, it must be able to be accompanied by other plants;... there are many restrictions, but compared with the research projects of Liu Yukun and Yang Yichen, it is still simpler.

"Star Tree 15 has matured for three years and its age is fifteen years. However, after reaching the age, it will not die. This is its biggest characteristic. It will only begin to change. Because it has perfectly integrated the characteristics of banyan trees before, it will change into an ordinary banyan tree after fifteen years, and its growth period will automatically be extended; Star Tree 15 is not very aggressive and can symbiotic with the trees generated around it. Except for the rare ore greenstone ice mineral that is absorbed, it will not absorb the basic ore; on the rhizome, once the fifteen-year period arrives, except for the supply of nutrients to the banyan tree, everything else will be integrated into the soil and become fertilizers that can be absorbed by all trees;..."

Han Zhen was very satisfied with the results of the three of them over a year. After encouraging them, they gave generous rewards. What made them most happy was that Han Zhen was also interested and decided to stay here for a month, attacking the problems they encountered during the experiment, and at the same time catalyzing the progress themselves. This was a huge help to the three of them and even the entire Special Research Institute, especially being able to watch the master take action by the side was the greatest temptation for them.

Star trees are not one type, but one type, a type of plants with the function of transforming and refining minerals. They are essentially different from plants with the function of transforming the planet's environment, but the two are still similar. Han Zhen left a piece of the seeds for the planet's transformation here. While giving Tan Gongyan and others the reference, they also asked them to consider the possibility of whether the functions of the two can be merged.

Is it necessary to combine the two? Han Zhen thinks it is still necessary. Since we can also include the rare minerals on it while transforming the planet, why not? Han Zhen has considered a lot of things. You must know that this modified planet will not only be used on his Han family in the future, but also will have a day to the outside world. At that time, we should first collect these planets and then deliver them. The benefits we get are not greater? If we say that the rare minerals contained in the soil of this administrative planet actually have a lot of them, but why

Countless planets have eventually become dead stars due to environmental problems, and it is very troublesome to use the environment to transform them? It is not because the planet is too powerful to turn it around. The two types of plants of different natures are considered the essence of the essence. How can they not reduce the original characteristics of the two and organically combine them together, which is a very worthy job to scratch their heads. This problem will take longer, and Han Zhen does not have time to do these things. Even if it can be completed, it is also a mentality that it is certainly a happy and unsuccessful.

In this month, Han Zhen spent half a month increasing the types of star trees from 46 to 197, and opened hundreds of pieces of test sites on the four mineral stars to plant them! The next analysis and care work will be the responsibility of this research institute; in the remaining half month, Han Zhen wanted to try whether he could integrate more than two star trees so that one star tree can adapt to more than two environments, or that the star tree has a high intelligence, automatic adjustment, and adapt to it after evolution! This is the same large-scale project as forcibly combining plants that transform the planet with star trees. If you can't make any progress, you can make a little progress.
Chapter completed!
