I walk in the past, continue the future

Chapter 88 The Skeleton of the Demon of Fire

"I will teach you the method, which requires your efforts." Xia Lian said.

"What do you need us to do?" Zangzi asked quickly.

"The Lord God has buried black wealth in this land. It is the blood and bones of the demon of fire. Just a little spark can ignite a raging flame and bring you warmth and light.

However, it is buried deep underground and can be very difficult to find. "

"Black wealth?" Zangzi frowned and thought for a moment, then he seemed to have thought of something and said excitedly, "I seem to have seen it before!"

"Oh?" Xia Lian's face showed a little interest.

"You come with us!"

Zangzi immediately jumped off the leader and led Xia Lian and the others through the underground cave.

This city that can live in tens of millions of people is so huge that it is quite terrifying. If there is no fifth element, it is absolutely impossible to build such a huge city without tools.

Although these tens of millions of people have nothing now, as long as they are properly commanded, it is inevitable to enter the industrial revolution in a short period of time.

Of course, whether this civilization has entered the industrial revolution is not necessarily related to the purpose of Xia Lian, but as the civilization level goes up, the fertility rate will naturally go up, and the more the number of people, the more potential believers and warriors will be. .

Although he ultimately wants to develop believers in a wider area, Yongye Xing also wants to ensure a sustainable development.

In the short term, if these people in the permafrost become stronger, they will be more evenly matched in the face of the inevitable war with the land in the future.

The people of Paradise possessed the best fifth element genes, and Xia Lian would not ignore them.

Soon, they went deep into the ground.

No one lives here, not even fluorescent rice. It is pitch black as ink, and there is a strange smell in the air.

Zang Zi took out a string of fluorescent rice from his body to illuminate, then walked to the corner and squatted down, picked up a black stone and held it in front of Xia Lian with both hands.

With anticipation in his eyes, he said, "Sir, is that this?"

Xia Lai used AS to scan the structure of the black stone in front of him.

But before the results were obtained, Einstein on one side said, "It's bituminous coal, you can't go wrong, and the purity is still very high."

"Bituminous coal." Anya stepped forward to take a closer look with curiosity on her face, "There is also this thing in Paradise, and they use it to burn some things.

But isn't this stuff poisonous? "

"That's right." Zangzi said, "When we dug here, we also found that this thing could be ignited. We tried to use it to keep warm, but some people died because of it, so we sealed it up."

"No wonder there is poisonous gas." Sparrowhawk was stunned, "This turned out to be the skeleton of the fire demon."

Sparrowhawk looked at the coal with fear in his eyes, "It's really evil, even if it's dead, it's still so dangerous."

"The main component it produces when it burns is called carbon dioxide," Einstein said. "It's also in the air, to be precise.

A human breath will also inhale a part of carbon dioxide, and the oxygen entering the body will be converted into carbon dioxide and discharged into the air. "

"What?" Sparrowhawk's expression changed, "We also release this poisonous gas?"

Xia Lian also smiled and said, "The rest of the gas released by the coal is highly toxic.

But carbon dioxide is not a poisonous gas. The reason why humans will die if they inhale carbon dioxide is that it occupies too much space in a closed space, crowding out the space for oxygen, making it impossible for people to breathe oxygen.

It's like the gods have taken away the oxygen around you at the beginning. "

Sparrowhawk recalled the original situation, the feeling of dying, he did not want to recall in his life.

After a pause, Anya seemed to realize something, and said in a panic, "But if humans inhale oxygen and exhale carbon dioxide, wouldn't the oxygen be less and less and carbon dioxide be more and more in the future?"

"Don't worry." Einstein said, "The world created by God is a perfect circular closed loop. All living things form a cycle in this circle. This is the principle of life.

Those of you who live in Paradise must have seen green plants, right?"

Sparrowhawk and Anya nodded.

"Green plants have something called chlorophyll, which, when exposed to sunlight, forms photosynthesis, which purifies carbon dioxide and converts it into oxygen.

In fact, there are huge numbers of these plants in the sea, including those glowing rice in this underground city.

However, fluorescent rice can absorb carbon dioxide and convert it into oxygen without being exposed to the sun. ' said Einstein.

Mushrooms are heterotrophic dung grass saprophytes and do not contain chlorophyll, so they cannot photosynthesize under normal circumstances, but this fluorescent rice is a genetically modified species.

Yingmi is prepared for the underground space. Otherwise, there are almost no plants in the frozen soil, and there is no need to be cold at all. These humans will all be suffocated due to the high concentration of carbon dioxide.

"So, if you study the remains of these fire demons in the future, you will find that there are some substances similar to plants in them." Xia Lian laughed.

"In the rules He established, the leaves and rhizomes of plants would accumulate on the ground after death in a very thick layer of black humus.

In a long period of time, it will be continuously buried underground due to changes in the crust, isolated from the air for a long time, and under high temperature and high pressure, such black combustible sedimentary rocks will be formed.

In this way, even if all the remains of the fire demon are used up, there will still be a steady stream of coal. "

"Is it the perfection of life?" Sparrowhawk's mood shook.

His face was full of respect, "It's really rigorous and full of wisdom. This huge system of nature should be the greatest masterpiece of the sun god!"

"No, his greatest masterpiece is not this world." Xia Lian looked at Sparrowhawk, "but you."

Sparrowhawk was silent, and after a while, he said in a low voice, "We're not worthy."

Xia Lian looked at him silently for a while, and from the first time he saw him before, he realized that this guy has a hand in PUA.

The most favorite thing for capitalists to see is this little leek. It's too dedicated to brainwashing yourself.

"But how do we use it?" Zangzi led the conversation on the right track.

"The reason why you are God's greatest masterpiece is because God has left the most precious thing in your brain, which is called wisdom."

Xia Lian smiled and said, "Using your wisdom, you can solve a little."

Under people's suspicious eyes, Einstein said.

"Since the smoke from burning it is poisonous, let it go outside and leave the world to purify them and leave its warmth alone."

"I know!" Anya said excitedly, "Build a chimney! Paradise does the same thing."

Suddenly, she seemed to realize something, and then said: "But this is underground."

"We can concentrate the chimneys in a place close to the surface." Xia Lian said.

"But how can people share the warmth it exudes?" Anya said suspiciously.

Einstein continued.

"You know, why do people still feel warm when they are sitting next to a fire, even though they are not in contact with the flames?

Because the heat of the flame can be transmitted through the air, the flame heats the surrounding air, and the air heats you.

This is called heat transfer. "

"I see, what you mean is that we build a bunch of furnaces in one place, use chimneys to get poisonous gas to the ground, and then heat something, and let those things carry heat to every building in this underground city in the house."

Speaking, Sparrowhawk seemed to realize something: "Water?"

"You are very smart." Einstein laughed, "Water is a material that can transfer heat very well, and it is easy to circulate.

We can use this principle to heat water into hot water, and then circulate it to every household through pipes.

We put something called a radiator in our home, which is made of the most thermally conductive material, and inside is a sealed circulation system.

The water we heat will be injected into the radiator through the pipe, and when the water flows in the pipe of the radiator, it will generate heated gas.

The air and objects below this temperature in the surrounding environment are heated. According to the principle of energy conservation, this will reduce the temperature of the water inside the radiator.

But these reduced water, after one turn, the low-temperature water returns to the boiler for heating.Repeated heating, cooling, and reheating in this way will increase the temperature of the air and objects in the room to achieve the purpose of heating the room. "

Xia Lian also opened his mouth and said, "And this, I call it, central heating."

"Central heating." Sparrow murmured absentmindedly, and began to calculate the feasibility of this method in his mind.

Then he shouted excitedly, "It's possible, maybe it's really feasible, this is really smart! Simple but full of wisdom, it's the most suitable for today's human beings!"

But then, he seemed to be splashed by a basin of cold water, and looked at the coals with some loss.

"God took great pains to put the future of humanity in our hands, and we never realized it.

If this method can be used in the paradise, and we can even live close to the permafrost, there will not be so many problems. "

After a pause, Sparrowhawk looked at Einstein, "Sir, what should we do?"

"I will provide you with drawings and material templates. You can use the fifth element to materialize it accordingly. You have so many people, and it should be built very quickly." Einstein said.

"Yes, it's not too late, it will only get colder in a few days." Sparrow Eagle looked at Zangzi, "Mr. Zangzi, I'll ask you to mobilize everyone."

Zangzi nodded, and then trotted out of here.

"Go and help, too." Xia Lian said.

Sparrowhawk nodded, and then walked out of the mine with Anya.

After the three of them left, only Einstein and Xia Lian were left in the mine.

Xia Lian turned his head, his smile gradually subsided, and he looked at the mine.

"professor."

"Huh?" Einstein looked at him suspiciously.

"Coal is formed by plants buried in the ground from ancient times, there is no other possibility, right?"

Einstein nodded, "At least, according to human cognition."

Then, he seemed to realize something, staring at the coal mines around him.

"If that's the case, then there would be no reason for these coal mines to exist underground in the permafrost." Xia Lian murmured softly.

"Perhaps because of continental drift?" Einstein said. "This continent used to be in the solar region?"

After a pause, Einstein rejected this point himself, "The seawater in the permafrost is frozen, and there can be no continental drift."

"Or, there is another possibility." Xia Lian murmured softly, "In this eternal night area, there were actually plants in the past."

Einstein frowned, "A plant that can survive in such temperature and darkness?"

Xia Lian did not speak, but fell into thought.
