Chapter 708: The Sound of Nature (Part 2)

The carriage is walking on the path. People sitting inside could vaguely hear the noise outside.

Laughter, shouts, and the sound of carts and carriages moving around, all of these came over one by one.

He was the only one in the carriage that Romon was riding in. He casually leaned his head on the back of the chair and began to think about the straw.

Just now, watching those big cars passing by him and hearing the student's inadvertent muttering, he suddenly had a thought, and once this thought came up, he couldn't suppress it anymore.

Romon was a little excited at this time. He was not only excited because this incident could bring benefits to his territory, but also because, through this incident, Romon finally found his own understanding of nature.

"Swamp gas!"

It was a sudden idea of ​​him to use all these straws to make biogas!

When we were on Earth before, there were few biogas applications in cities, and in some well-built towns, because a large amount of food was grown. After each harvest, many branches and leaves of the crops were collected.

Incineration is impossible. This practice is not only a waste of resources, but also a pollution to the environment.

In some rural areas, these straws and corn leaves are transported to the biogas chamber to be turned into biogas, which can provide some flames.

As an environmentalist, Luo Meng once made a special effort to study the application of rural biogas, and he still has some understanding of this aspect.

In this world, no coal has been found. After looking at the history, it is said that the history of this world is only about 100,000 years. It is natural that coal and oil cannot be formed.

In fact, Romon even believed that without these two, this world would never be able to have the industrial revolution on Earth.

There is still lightning, but it is the wind and water elements that release energy, and this kind of thing has not been applied.

Except for extremely extravagant families, magic may be used to maintain the stove, so as to achieve the purpose of cooking and heating. I believe that no normal person would choose such a perverted method.

Naturally, twigs and wood became the only common fuel.

But there are so many human beings. Every day, there are so many people who need to cook, eat, and keep warm in winter. However, the growth of trees is extremely slow.

Even the fastest growing tree species will never grow without a year or two.

It takes a lot of wood to cook a meal, and in winter, the stove is always burning.

It is precisely for this reason that many elves and druids have great prejudice against humans, thinking that it is precisely because of the appearance of humans that the beauty of the natural world will be destroyed.

Many conflicts are like this, because of one or several things, they eventually accumulate into disasters.

If there is biogas, it will be different. Animal feces and plant branches and leaves are fermented and decomposed by various microorganisms. Biogas can be produced.

Biogas can be used for cooking and heating, and it is also convenient, clean, and environmentally friendly. The more Luo Meng thought about it, the more he felt that he should do such a thing.

Moreover, the feed liquid and sediment discharged after fermentation by the biogas plant contain relatively rich nutrients and can be used as fertilizer and feed.

"First, it must be confirmed that this theory still exists in this world."

"Secondly, new spells must be developed to replace the effect of cement sealing. The fifth-level mage spells and the fifth-level druid spells both have the ability to turn mud into stone, which can turn sand into stone, but this is too demanding Well, I just need to cover the soil in the basement with a thin layer of hard shell to prevent leakage, and it is best to only have a first-level spell, so that the biogas can be popularized."

"Thirdly, it is necessary to develop a spell to speed up the fermentation of microorganisms, or to specially cultivate a harmless creature of this type to speed up the fermentation and decomposition, so that it can actually enter thousands of households."

"Incineration is too uneconomical, and only limited flame heat is obtained. Even if the ash is applied to the land, it is only less than one-tenth of the decomposition and fermentation. This is too wasteful. Once the fermentation process is accelerated, the biogas will be turned into The manufacturing plant of bio-fertilizer is even more useful.”

Just as he was still thinking, the carriage stopped, opened the curtain and looked out, the huge eagle statue in front of the Giant Eagle Academy had already appeared in sight and arrived at the place.

After getting off the carriage, Romon plunged into the headmaster's office. During the lunchtime, he was always delivered, but no one came out.

"Kasirer." At around four o'clock in the afternoon, Jayfa walked over to the classroom with a thick notebook in hand, just in time to see Kassirer coming back from the outside, and he waved to Kassirer. "Come here, and send this notebook to your teacher."

"Instructor Jayfa, this is..." Cassirer took the note in his hand and found that it was quite heavy. So, I asked curiously.

"It's a collection of common plants in this world. Your teacher said he wanted to take a look, so I dug it out for him. I'm going out right now. You can send it there for me." Jiefa said.

Cassirer showed a brilliant smile: "Don't worry, Instructor Jaffa, I promise to complete the task!"

Jaffa nodded in satisfaction, turned and left.

Cassirer carefully opened the notes in his hand, and found that all of them were hand-transcribed plant encyclopedias. This thing is really good.

"When the teacher runs out, I'll borrow it and copy a copy, and keep it for myself." After making up his mind, Cassirer took the notebook and walked to the principal's office.

The principal's office is at the southeast corner of the college, just follow the corridor and go all the way to the end.

The neighborhood is quiet, and when there is nothing to do, no one will easily disturb the people staying here.

When Cassirer walked over, he found that the door was ajar. With a light push, the door opened quietly.

But as soon as he tiptoed a step, Romon's faint voice sounded in the principal's room with a suite: "Casirer, come in."

Cassirer gently closed the door and walked towards the inside.

The outer room of the principal's office is used to receive guests, and the inner one is the office room.

When Cassirer walked in, Romon was scribbling something on the table. Seeing Cassirer coming in, he raised his head and asked, "What are you holding in your hand, are instructor Jaffa's plant notes?"

Cassirer handed over the note with a look of admiration: "Teacher, you are too good. Is there anything in this world that you can't guess?"

Luo Meng took the note, and didn't read it right away, but smiled: "There are many things that I can't guess, for example, I can't guess how much food you can eat a day."

Cassirer smiled and sat down beside Romon. "Recently, everyone's appetite has increased, but we have also grown in size."

"That's right." Romon nodded.

This group of little guys is just growing, and because of training, the daily appetite. They are all rising, but he has money and food, and he doesn't care about what little they eat. He even told the cafeteria to improve the quality of food a little bit, so as to supplement enough nutrition for these students.

"Teacher, what are you busy with? You have been busy since you came back from the field. Is it... something to do with those straws?" Seeing that Romon was drawing something with his head down, Cassirer moved his head to look curiously. Ask at the same time.

What appeared in Cassirer's sight was a blueprint, which seemed to be a pool, with some pipes and extended patterns.

Cassirer had never seen such a strange picture before, after a few glances, he still didn't quite understand it. "Teacher, you have been busy for a long time, are you just drawing this?"

Romon said, "You're blocking the light."

Cassirer smiled and sat back, but his neck was still stretched out to this side. It seemed that if Romon didn't explain clearly, he would stay here forever.

In desperation, Romon put down the pen in his hand: "You are curious about what I am drawing now, aren't you?"

"If the teacher really can't tell, I won't ask." Cassirer said.

For this student, Romon had a good impression. Seeing that he wanted to know, Romon didn't need to hide it after thinking about it, so he pushed the blueprint that he had scribbled for a long time before finally drawing it in front of Cassirer. Explanation: "This drawing is the result of my recent work. In fact, you guessed it right just now. I have been busy for a long time. In fact, it is really for those straws. Look at this picture, what can you see? cannot?"

Hearing what the teacher said, Cassirer looked uprightly. After watching it for a while, he understood a bit: "Teacher, are you going to put all the straws into this pond? It's strange, you need to put water in it? And seal it up? Teacher, I don't quite understand what you mean. Could it be that those straws were brought back for cooking?"

Luo Meng smiled: "This is a secret for the time being, and you will know it in a short time."

In the next few days, as expected, Luo Meng led people to dig ponds and pipes in the school, and became busy.

There are quite a few people who are curious, but there is no one who can see the way. Even Jaffa and other instructors were puzzled by what Romon did.

Every time he asked Romon, he always said, "It won't take long, and you will know."

Being prevaricated, it made everyone in the college feel itchy.

Finally, on this day, Romon called Nick, Cassirer and others, saying that they were here to watch his experimental results.

A group of people came to the sealed pool first, and Romon explained a little proudly: "Everyone must be curious, I brought the straws here, and used a small magic circle to quickly catalyze them. Why, now, let me reveal the mystery to everyone."

As he spoke, he led the crowd to the nearby kitchen, where a fire was being lit for cooking.

But what made everyone curious was that there was no crackling sound of branches being burned in the stove, but flames were still radiating from it.

With a smile on his face, Romon explained: "This is the result of my experiment. I used the rotten straw to produce fire. From today on, our school cooks and keeps warm, and there is no need to cut down trees anymore. It's a small step, but druids don't need to chop wood and burn fire, whether it's for their own cultivation or for giving back to nature, it's definitely a good thing."

"That's true!" Jefa couldn't help but stepped forward to check, his spiritual sense felt a pipe, and the gas released from this pipe formed a flame.

Seeing that everyone was still in shock, he decided to throw another bomb in: "These rotten things can also be used as high-quality fertilizers, and returned to the fields and forests... When the next crops are harvested, they can be used again. Utilize those straws to make it a virtuous circle...Of course, animal dung and rotten leaves can also be used. Compared with cutting wood and burning fire, using the gas produced by these rotten objects to start a fire Come and be cleaner."

"However, you have all seen that although this is successful, it requires a lot of investment, for example, the magic circle to speed up fermentation and decomposition, and the materials used for sealing."

"Our next goal is to make it cheap, and it's best to compress it to the point where there are only first-level spells, or even zero-level spells."

After a pause, Romon began to explain his philosophy.

"First of all, nature is balanced, and unbalanced nature will brew all kinds of bitter fruits."

"Secondly, I don't agree with narrow feralism. There are many druids who strongly oppose civilization, hunting and farming activities. I don't take this."

"Metabolism is the foundation of nature. What is metabolism? It is decomposition and nurturing."

"The so-called decomposition means not being able to produce substances that cannot be decomposed by nature, or other things. They are natural cancers, and decomposition is for the next care."

"On that basis, we advocate for diversity."

Jayfa understood what he said earlier, but he didn't understand the diversity.

"I say metaphorically, from the highest point of view, cutting down trees to burn them does not destroy the foundations of nature, because the ashes of the wood return to nature."

"However, it has destroyed natural diversity, deforested a lot, and destroyed a lot of flora and fauna."

"Nature is not only the cycle of elements, but also the rich ecology and life constructed on this basis."

"Ecological agriculture, first of all, does not violate the balance, and secondly, in the context of the principle of decomposition and tending, biogas can accelerate the decomposition of straw and other plants, which is not against nature."

"And, because of this accelerated decomposition, not only can flames be obtained, reducing wood felling, but it can also be returned to the earth in the most natural form—biological fertilizer, which fertilizes the farmland, nurtures the life of the next generation, and makes them more prosperous. "

"Biogas is only a small step in ecological agriculture, but it has fully explained my concept of nature and the essence of ecological agriculture."

"There will be more ways to come out in the future. I hope everyone will have a good experience today, and also bring those students to visit, let each student go back, write a copy of their feelings, and I will review it."

"I hope that everyone can understand my words carefully and study together so that this druid discipline can develop from scratch."

"Of course, we can use love to describe this kind of maintenance of diversity. I believe this is rarely resisted." Romon said meaningfully.

Humans like to eat this set the most. Love is an eternal dream. Put love on the need to maintain diversity, love forests, animals, and ecology. After that, it shouldn’t be rejected by human beings, right?

Of course, this cannot be said now.

The druids present were especially shocked.

On the path of the druids, because they have always opposed human beings and nature, and even agriculture and nature, these druids have felt difficulties on the road to promotion.

But at this time, the idea proposed by Romon cleared the way.

No wonder Romon, who can become a fourteenth-level druid, will definitely become an arch druid in the future.

As for Jayfa, he had always had faint doubts before, but now, all doubts have been swept away.

Natural druids must not put forward such a concept. This is the difference of fundamental truth, and it must not be covered up or hypocritical.

Romon didn't notice that after he finished speaking, the World Tree swayed happily in the Shennongjiao space, and above it, every word he said turned into golden characters.

After floating for a while, these golden characters rushed into the branch that accepted the belief. Affected by this, the branch suddenly changed color, and the faint golden color dyed the branch.

Moreover, on the branch, Romon's image emerged, and the holy light transmitted to the distance also underwent subtle changes.
