Chapter 708 The Sound of Nature (Part 2)

The carriage was walking on the path, and the people sitting inside could still hear the noise outside.

The laughter, the shouts, the sound of carts and carts constantly walking, all of them came over.

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

Just now, watching the big cars passing by him and listening to the student's inadvertent muttering, he suddenly had an idea, and when this idea came, he could no longer suppress it.

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

“Biogas!”

He suddenly thought of applying all these wheat rods to create biogas!

In the past, when I was on Earth, there were few biogas applications in cities. In some towns that were well-built, there were a large number of grains planted. After each bumper harvest, many crop branches and leaves 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 wheat poles and corn leaves are transported to the biogas chamber and turned into biogas, which can provide some use of flames.

As an environmental protector, Romon once deliberately studied the application of rural biogas, and he still has some understanding of this aspect.

In this world, no coal was found. After watching history, it is said that the history of this world is only about 100,000 years, and it is natural that coal and oil cannot be formed.

In fact, Romon even believed that without these two, there would never be an industrial revolution on earth in this world.

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

Except for extremely luxurious families, they may use magic to maintain the stove fire to achieve the purpose of cooking and keeping warm. I believe that no normal person will choose such a perverted method.

Naturally, branches and wood become the only common fuel.

But there are so many humans. Every day, there are so many people who need to cook and eat, and they need to keep warm in winter. However, the growth of trees is extremely slow. Even the fastest-growing tree species will definitely not grow in less than a year or two.

A lot of wood is needed to cook a meal. In winter, the stove fire is often ignited.

It is precisely for this reason that many elves and druids have great prejudice against humans, believing that it is precisely because of the emergence of humans that the beauty of nature has been destroyed.

Many contradictions are like this, because one or several things eventually accumulate into disasters.

If there is biogas, it is different. The animal feces, plant branches and leaves can produce biogas after fermentation and decomposition of various microorganisms.

Biogas can be cooked, heated, and is convenient, clean, and environmentally friendly. The more Romon thinks, the more he feels that he should do such a thing.

In addition, the feed liquid and sediment discharged after fermentation by the biogas device are rich in nutrients and can be used as fertilizers and feeds.

"First, it is necessary to determine that this theory still exists in this world."

"Secondly, new spells must be developed to replace the effect of cement sealing. Level 5 mage spells and level 5 druid spells all turn mud into stones, which can transform mud into stones, but this requirement is too high. I only need to have a thin layer of hard shell in the basement to prevent leakage. It is best to have only level 1 spells, so that biogas can be popularized."

"The third is that it is necessary to develop spells to speed up the fermentation of microorganisms, or to specifically cultivate a kind of harmless creature to accelerate fermentation and decomposition, so that it can actually enter thousands of households."

"Incineration is too uneconomical, and only a limited amount of flame heat is obtained. Even if the ash is applied to the land, it is only less than one-tenth of decomposition and fermentation. This is too wasteful. Once the fermentation process is accelerated, it will be even more utilized to turn biogas into a manufacturing site for biological fertilizers."

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

Getting off the carriage, Romon plunged into the principal's office. During lunch, people were sent to him, but no one came out.

"Casil." At around four o'clock in the afternoon, Jefa walked over with a thick note and saw Casil coming back from outside. He waved to Casil. "Come here and send this note to your teacher."

"Instructor Jiefa, this is..." Cassill held the notes in his hand and found that it was quite heavy to get it, so he asked curiously.

"It's a summary of common plants in this world. Your teacher said he wanted to take a look, so I took it out for him. I'm going out soon, you can send it for me." Jiefa said.

Cassil showed an extremely bright smile: "Don't worry, Instructor Jiefa, please ensure that you complete the task!"

Jiefa nodded in satisfaction and turned around and left.

Then Cassil carefully opened the notes in his hand and found that it was full of artificially copied plants, which was really good.

"When the teacher has used it, I will borrow it and copy it, and leave it to myself to look back and see." After Cassill made up his mind, he took the notes and walked towards the principal's office.

The principal's office is located in the southeast corner of the college, just along the corridor and walking to the end.

It is quiet nearby. When there is no trouble, no one will easily disturb the people who stay here.

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

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

Cassil closed the door gently and walked towards the inner room.

The outside room of the principal's office is used to receive guests, and the inside is the office room.

When Casil walked in, Romon was changing something on the table. When he saw Casil come in, he raised his head and asked, "What are you holding in your hand? Is Instructor Jeffa's plant notes?"

Cassil handed the note over with admiration: "Teacher, you are so amazing. Is there anything you can't guess in this world?"

Romon took the notes and did not read them immediately, but smiled: "I can't guess too many things, for example, I can't guess how much you can eat in a day."

Casil smiled and sat down next to Romon. "Everyone's appetite has grown a little lately, but we're also growing."

"That's true." Romon nodded.

These little guys are developing and training, and their daily appetite is increasing. However, he has money and food. He doesn't care about what they eat at all. He even instructed the cafeteria to improve the quality of the food a little more and supplement these students with enough nutrition.

"Teacher, what are you busy with? You have been busy with your back from the field. Is it... related to those wheat poles?" Seeing Romon lowering his head and drawing something, Casil curiously turned his head over to watch it, and asked at the same time.

What appeared in Casil's sight was a drawing, which seemed to be a pool, as well as some pipes and extended patterns.

Cassil had never seen such a strange picture before. After a few glances, he still didn't understand. "Teacher, you have been busy for a long time, are you painting this?"

Romon said, "You blocked the light."

Casil then sat back with a smile, but his neck was still stretched toward this side, as if Romon didn't explain clearly, he would stay here and stay without leaving.

In desperation, Romon put down the pen in his hand: "You are curious about what I'm drawing now, are you?"

"If the teacher really can't say it, I won't ask." Cassill said.

Romon had a good impression of this student. Seeing that he wanted to know, Romon thought that there was no need to hide this matter, so he changed the drawing himself for a long time before finally drawing it in front of Cassill and explained: "This drawing is the result of my past. In fact, you really guessed it right just now. I have been busy for the past half a day, but in fact, it is really for those wheat poles. Looking at this picture, can you tell what can you not do?

After hearing what the teacher said, Cassil looked openly. After looking at it for a while, he understood a little: "Teacher, are you planning to put all the wheat stems into this pool? It's strange that you need to put water in it? And seal it? Teacher, I don't understand what you mean. Isn't the wheat stems being transported back to cook for the fire?"

Romon smiled: "This is kept confidential for the time being, and you will know it soon."

In the next few days, Romon indeed took his men and started digging pools at school, opening pipes, and busy themselves.

There were many curious people, but none of them could see the trick. Instructors such as Lian Jiefa were confused about what Romon did.

Every time I asked Romon, he said, "It won't take long to know."

The excuse made everyone in the academy feel itchy.

Finally, on this day, Romon called Nick, Cassill and others to watch his experimental results.

A group of people first came to the sealed pool, and Romon explained with a little smugness: "Everyone must be very curious. I brought the wheat stem here and used a small magic array to quickly catalyze them. Why? Now, I will explain the answer to you."

As he said that, he led everyone to the kitchen next to him, where he was making a fire and cooking.

But what made everyone curious was that there was no sound of branches burning in the stove, but there was still flames on it.

Romon's face was filled with a smile and explained: "This is my experimental result. The rotten wheat pole made a fire. From today on, our school will cook and keep warm, and we will no longer have to cut down trees. Although this is just a small step, the druid does not need to cut down wood to burn fire. Whether it is to practice or to give back to nature, it is definitely a good thing."

"It's really like this!" Jiefa couldn't help but step forward and checked. His spiritual sense felt a pipe, and the gas released by the pipe formed a flame.

Seeing that everyone was still in shock, he decided to drop another bomb in: "These rotten things can also be used as high-quality fertilizers and return to the fields and forests... When the next harvest is harvested, the wheat poles can be used again to make it a virtuous cycle... Of course, animal feces and rotten leaves can also be used. Compared with cutting wood and burning fire, using the gas produced by these rotten things will make the fire cleaner."

"But you all saw that although this was successful, you must have a lot of investment, such as the magic array that speeds up fermentation and decomposition, and the materials used when sealing."

"Our next goal is to make it cheaper, preferably compressing it to the level of only one level spell or even zero level spells."

After a pause, Romon began to explain his ideas.

"First of all, it is naturally balanced, and imbalance will naturally produce all kinds of bitter fruits."

"Secondly, I do not agree with narrow wildism. There are many druids who strongly oppose civilization and hunting and farming activities. I do not take this."

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

"The so-called decomposition means that substances or other things that cannot be decomposed by nature are natural cancers, and decomposition is for the next nurturing."

“On this basis, we advocate diversity.”

Jiefa understood everything before, but he didn't understand the diversity.

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

"But it destroyed the diversity of nature, a large number of forests were cut down, and a large number of animals and plants were destroyed."

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

"Ecological agriculture is first of all, not contrary to balance, and secondly, it is about the principles of decomposition and nurturing. Biogas can accelerate decomposition of wheat stems and other plants, which does not violate nature."

"And, due to this accelerated decomposition, not only can the flame be obtained and the wood cut down can be reduced, but it can also return to the earth in the most natural form - biological fertilizer, fertilizing the farmland, nurturing the lives of the next generation, and making them more prosperous."

"Biogas is just a small step in ecological agriculture, but it has fully demonstrated 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 bring those students to visit, so that each student can go back and write a piece of insight. I want to review it."

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

"Of course, we can describe this kind of maintaining diversity with love. I believe this has been rarely resisted." Romon said meaningfully.
