I brought a Jurassic

Chapter 221 Asking
The matter of submarines was banned and they were placed in the mountains. Relevant protection facilities were built and a group of scientific researchers were conducting research there.

When Wang Luo got up, his classmates had already gone to class. After getting up, washing up, and brushing his teeth, he ran to the Jurassic World. With the submarine soldiers’ respectful service, he ate several large cans of food before running back to the real world and going straight to the playground to see the pigpen.

"You still know how to show up, kid. You handed over all the work to an old man like me, and you disappeared without a trace. Do you have the nerve to do that?"

As soon as they met, Uncle Qiu pointed at Wang Luo and started to speak in a sarcastic manner.

"Hey, those who are capable should do more work. You are an expert in pig farming, I dare not compare with you. This pig pen is well built. Let the pigs be released after a few days of drying. A few days ago, I found a nest of wild boars in the mountains. I will catch them all and let them give us meat!"

I looked at the pigpen and it was no different from the rural pigpens in later generations. The manure ditches were dug very neatly and evenly spread with cement.

"I built everything according to your drawings. It's really good. Connect the water pipes and flush it every day to make it clean. There's no need to put pigs in. Just throw the hay in. By the way, why did you build that big pond? And you even made two feed holes. Is it to store manure? Why do we need to store it? We can just ask the villagers nearby to bring it back home every day, or we can grow vegetables ourselves. Isn't it a waste to build such a big pond?"

Uncle Qiu pointed at the relatively large cement pool and asked Wang Luo in confusion.

"Hehe, this is a good thing. It would be a waste to pile up the feces and then put them on the field after fermentation. I decided to build a septic tank to collect biogas. Then I would build a stove to make it more convenient to boil water and cook. It can even generate electricity. I am not familiar with how to generate electricity, after all, it requires a special generator, but it is no problem to cook and boil water, especially in summer. It saves coal money and does not heat the food. What a good thing! Besides, the feces are better for use on the field. The south has been using it for a long time, but we have never seen it here."

Biogas is not a rare thing in this era. It was introduced as early as 1930, and in 1958, many provinces and cities across the country were swept by a biogas craze. However, due to insufficient research, it was finally abandoned. It was not until 1970 that research began again. But as a person from later generations, and a pig farmer at home, Rocco was very familiar with the biogas king. He used it for cooking and boiling water. There was even no special gas generator in the early days, and pig feed had to be cooked manually using it.

The reason why there is not much biogas in rural areas after the 21st century is not because people don't want to use it, but for various reasons. The first is the problem of raw materials. With the acceleration of urbanization, many young people in rural areas choose to go to big cities to find employment opportunities. The reduction in family population has led to a decrease in the number of domestic chickens, ducks and pigs. Naturally, biogas raw materials have become a headache. What's more, now every household in rural areas has access to electricity and water, and some rural areas even have access to gas. The demand for biogas is also declining.

In addition, there is another shortcoming of the biogas digester that cannot be ignored, that is the instability of the gas output. This is because the fermentation of the biogas digester is closely related to the climate temperature. In the hot summer, the fermentation is fast and the gas output is high, resulting in an oversupply. However, in the winter, there will be a shortage of gas supply, which greatly affects the farmers' usage efficiency.

Finally, there is the issue of safety. Biogas is composed of many gases and is a flammable gas. When these flammable gases reach a certain concentration, a spark will ignite them and eventually cause an explosion. In addition, the waste in the biogas pool needs to be cleaned up in time. If it is not cleaned for a long time, it will stink and easily produce toxic gases. The large open hole may also cause people to fall accidentally.

But in this era, the above shortcomings are not shortcomings. In this era when everything is in short supply, it is enough to save money and don’t need to consider other things. Besides, Wang Luo strictly follows the plan in construction and can ensure safety.

"It's just like the gas lamps of the past!"

Uncle Qiu understood what Wang Luo said as soon as he thought about it.

"Yes, that thing. We don't expect it to generate electricity, but it can be used to cook and feed pigs. Just wait and see. It's guaranteed to work well!"

When the two were chatting animatedly, a student ran over and said that his elders from his family came to see him.

Wang Luo then stopped chatting and ran to the front of the school. Li Da was waiting for him at the school gate, smoking.

"I thought you were not in school. What a joke it is to run around here all day long!" Li Da patted his shoulder and scolded him.

"I'm just messing around when I have nothing to do. Why do you come to see me? Do you want to see my pig farm?"

"I just happened to be passing by, so I came to take a look. Let's go and talk in the car!"

After getting on the bus, he took out a newspaper and handed it to him, pointing to the content and asking him to read it: "Tell me, what do you think?"

Wang Luo took a quick look and saw an article protesting the disappearance of a submarine.

"Why are you showing me this? Just fight if they come. Why are we afraid of them? This is your business. How can a student like me understand this? Besides, this is the navy, not the army. If it were the army, I might be able to kill a few enemies on the battlefield, but at sea, I can do nothing!"

Wang Luo pretended to be innocent and looked at Li Dadao with his clear big eyes.

"You really can't do anything?"

After listening to Zulong's words last night, Li Da felt more and more that something was wrong. So he ran over early in the morning to sound out Wang Luo. Regardless of whether Wang Luo was the Flying Knight or not, there was nothing wrong in sounding out the question. After all, both he and others were curious about who this Flying Knight was. If there was any clue, he would come and ask, just in case he could find out something!

So Li Da looked directly into Wang Luo's eyes and asked.

"What can I do? That's the sea, a battle between huge steel cannons, not a small ditch. What can a student like me do? You're so surprised. Why are you suddenly asking me a question that has nothing to do with it? It's totally incomprehensible!"

Wang Luo complained and tried to change the subject. He had already started thinking in his mind, "Did I get discovered? That shouldn't be the case. I haven't shown my real face before. No one has seen me. This is a test, an absolute test!"

So he just didn't know anything when asked.

"That's strange, could it really be a coincidence? But this is too much of a coincidence!"

He murmured a few words in a low voice, and then spoke again: "Boy, don't hide anything from me. Your father and I are brothers in life and death, and we will never do anything to you."

"What's wrong with you? Uncle Li, I've been under your watch since I was a kid. You know everything about me. Today, you asked me to read the report first, and then you said I was hiding something from you. What exactly brought you here today?"

Wang Luo used the method of turning the tables to be very good. Now it turns out that he is asking Li Da.
