Zhu Yan and Chen Lan didn't keep pondering, Reporter Zhou, the two senior brothers and Teacher Chen came to find them together. Pen? Interesting? Pavilion wWw. ｂiquge。 ｉｎfo

There are some problems in the plastic greenhouse covered yesterday, the temperature is still not high enough, and the heat generated by humus fermentation alone cannot meet the temperature requirements in the greenhouse. There is not enough light here, and even in a good weather like today, the strong sunlight does not last more than three hours, and it is impossible to rely on the light to warm up.

There are two ways to solve the problem according to local conditions: one is to introduce the hot spring into the greenhouse, and use the hot spring water of sixty or seventy degrees Celsius to heat the shed, which can naturally meet the temperature requirements; The second is to use charcoal fire heating in the shed, which can not only increase the temperature, but also increase the carbon dioxide content in the shed and accelerate the photosynthesis of plants.

However, the former has to solve the problem of water seepage in hot spring ditches, which have a high content of mineral elements and will cause plant death if they seep into the soil. The latter can be in a short period of time, but in the long run, how can there be so much charcoal in the base? Destroying forests on a large scale to burn charcoal is not what they want.

The temperature requirements of a small greenhouse have stumped everyone, and it seems that the energy problem needs to be solved.

The energy in the mountains is currently known to have carbonized wood, but the reserves will not be too much, and coal, oil and the like may not be available. Of course, the temperature of the hot spring water is high enough, reaching 60 or 70 degrees, and it should also be used as an energy source. In addition, wind power and water power are also available, but the cost of use is high and is not considered.

If the hot spring water is introduced into the greenhouse, it is best that the iron pipe can be wrapped around the greenhouse a few times, and the good thermal conductivity of the metal can be used to completely raise the temperature in the greenhouse.

This method is good, Zhu Yan even thought that the temperature difference can also be used to generate electricity, as long as there is electricity, don't worry about the lack of light. The principle is to use a liquid with a low boiling point to vaporize into steam at a high temperature, transfer it to a low temperature and then liquefy, and then transfer it to a high temperature for re-vaporization to form a cycle, in which the vaporized steam can promote the work of the generator.

Generally speaking, as long as there is a temperature difference of more than a dozen degrees Celsius, it can be used to generate electricity. The temperature difference between the hot spring water here and the environment can be as high as more than 40 degrees Celsius, which can fully meet the requirements of power generation. The kind of liquid with a low boiling point, Zhu Yan also thought of it, it is enough to use n-pentane, the boiling point is 36 degrees Celsius, and it will already boil in the hot spring water, and it will liquefy in the greenhouse, and the liquefaction process can be exothermic.

As soon as Zhu Yan told everyone about this idea, they immediately approved it, and now the main problem has become insufficient funds and difficulties in transporting materials. The transportation of materials can also be transported in batches and many times, but it is difficult to move an inch without money!

Reporter Zhou shouted that they wanted to take out all their savings, and the two senior brothers and Mr. Chen also wanted to pay money, but even if they put all this money together, it would not be much, and the development of the base in the future would definitely need a large amount of money, which could only be a drop in the bucket.

After some discussion, everyone finally decided to go to the mountains to collect some medicinal materials and mountain goods for money, to tide over this difficulty for the time being, and to talk about the funds needed for future development.

The task of finding medicinal materials naturally fell to Zhu Yan and Chen Lan, and for them, it was really not much difficulty. Especially Zhu Yan, the upgraded "extrasensory perception" function is even more powerful, and the plants, trees, and stones within a radius of a hundred miles have not escaped his perception, and even the minerals in Fannei, which are a few miles deep underground, are all visible.

As soon as they said goodbye, Zhu Yan and Chen Lan said goodbye to everyone, took their swords, and flew to the depths of the mountain again on the crow.

Sitting on the back of the divine crow, Zhu Yan and Chen Lan both turned on the spirit stove, and hundreds of millions of wisps of heaven and earth vitality poured into their bodies from all directions, and then formed countless clear pictures, just like the ground photos taken by spy satellites. The evil aura in the mountains had long since disappeared without a trace, which also made them breathe a sigh of relief, after all, the last few battles had left a deep impression on them.

When the crows approached the sky above Tianchi, they quickly sensed the breath of a large number of wild ginseng, most of them were concentrated in the primeval dense forest on the east side of Tianchi, and there were even many hundred-year-old ginseng breaths.

It turns out that the east side of Tianchi now belongs to the Bangzi Country, and the development of Changbai Mountain by the economically backward Bangzi Country is far inferior to that of Huaxia Kingdom, and everything is still original.

Regarding cross-border ginseng picking, Zhu Yan and Chen Lan have no scruples, nor do they have any guilt. As cultivators of their realm, it is difficult for those who come from heaven to earth to be discovered by the border guards. And anyone who is familiar with the history of Changbai Mountain will ignore the sticks' so-called sovereignty claims over Baitou Mountain.

The history of human activities in Changbai Mountain can be traced back to primitive societies. In terms of historical structure, Changbai Mountain has always belonged to the Huaxia State, and has successively become the jurisdiction of the Han Dynasty "Juli County", the settlement of the end of the Tang Dynasty, the location of the Tang "Bohai State", the founding place of the Liao "Dongdan State", the Liao-Bohai "Ding'an State" territory, the Liao-Bohai "Xingliao State" territory, the Jin Dynasty Haolazy Road territory, the late Jin Dynasty "Dongxia State" territory, the Yuan Kaiyuan, Liaoyang 2nd Road Division, and the Ming Sanwei Division. At the end of the Yuan Dynasty and the beginning of the Qing Dynasty, the Changbai Mountain was the place where the Qing Dynasty rose, and it was therefore banned as a dragon vein. During the Republic of China, the Changbai Mountains belonged to Jilin Province and Fengtian Province.

After the founding of the New China Kingdom, the great leaders Grandpa Mao and Grandpa Zou were fooled by the brothers of the socialist camp of the Stick Country, and they couldn't drop the top hat of the "Big Brother", and finally gave half of the Changbai Mountain to the Stick Country. Forced by the leader's obscenity, the common people of the Chinese country dare not speak out, this territory is the common property of all the Chinese people, the so-called every inch of land must be fought for, how can one or two leaders decide with one word?

Zhu Yan and Chen Lan's target was locked onto the primeval dense forest on the east side of Tianchi, and they commanded the divine crow to slowly descend. Then, Zhu Yan closed his eyes again, turned on the spirit stove, and shrouded the dense forest within a radius of dozens of miles in his perception, while Chen Lan took up the light skill and rushed away from the top of the tree.

One, two, three...... Wild ginseng is constantly being discovered, and at least it is more than 20 years old. Every time she found a plant, Chen Lan rushed to it and quickly put it into her bag. In less than half a day, they have picked more than 60 old ginseng plants, including 10 old ginseng plants that are about 100 years old.

If all these old ginseng are sold, they are worth at least tens of millions, and they are definitely priceless. And with this money, the base will not be short of funds for at least ten years, and even the purchase of a helicopter will be enough.

Zhu Yan's divine consciousness was still in the mental space, and he was about to withdraw his perception from the countless white heaven and earth vitality qi, but he suddenly found that the roots of the mind tree were also pulling countless light purple vitality filaments at some point.

This is something that has never happened before, in the past, there were filaments of vitality connected to the leaves, telepathy, and energy information from the surrounding environment, but there were never filaments of vitality found on the roots. Moreover, the light purple vitality light point indicates that the energy it carries is higher, for example, there are more purple light spots in the human vitality filament, so what are these purple vitality filaments on the roots? Will there be any unexpected surprises?

Zhu Yan couldn't wait to know the secret, and his perception suddenly merged into the countless light purple filaments of vitality......
