The moonlight was like silver, flowing freely in the forest where the night owls screamed. The leaves outside the car window seemed to glow with a silver glow. The ghost eagle couple on the branch took turns dozing off, and they also took turns looking into the distance. The white horse stood in the tent, not flicking his tail to drive away the mosquitoes. Outside the bus, Xiao Bai and Xiao Hei hugged Xiao Huang, their eyes opening and closing from time to time, and occasionally turning their heads sideways to listen to something. The old dog lay under the bus, alert to all movements around him.

Through the car window, you can see that the chairs in the bus have been removed a lot, and a large bed is placed inside. Bai Suzhen waited for Xu Xian for thousands of years, the Cowherd and Weaver Girl saw her once a year, and Jack gave up the chance to live for the sake of the shredded meat......

At this time, storytelling is actually quite troublesome. The main reason is that the various backgrounds or mythological or technological elements involved are not easy to tell, and they need to be explained separately. Even though Cai Rong had read dozens of books selected by the forest trails, her brain still didn't quite understand the myths or technologies that didn't exist.

"King, what does the kingdom of God look like?"

After explaining what a steam engine was and why the Europeans had sailed to the Americas, Harvest muttered.

The kingdom of God here naturally refers to the Hereafter. Lin Ji's things are all from the later generations, and he himself is a little taboo to mention this, because he himself can't understand his own state, so everyone has always called it the Kingdom of God. Over time, although Lin Ji didn't mention much about the situation in later generations, everyone slowly guessed that it was a huge system.

Lin Ji looked at the bright moonlight outside the window, it was difficult to see such a bright moonlight without such pure air in later generations.

Picking mushrooms was basically the most understanding person in the world, and he suddenly felt that it wasn't necessarily a bad thing to talk to her about it, so he said broadly: "There are seven billion people in that place." produced accomplishments that at least dazzled me......"

"How much?" This sentence alone surprised Cai Fu, "Seven billion? Is it the 100 million after 10 million? What is the population of China now, 500,000, right? Then we ......"

Cai Fu subconsciously wanted to calculate the gap, and remembered something, grabbing Lin Ji quite nervously and trying to escape from the car, and even talked some nonsense.

"Steady, steady. I'm talking about that place. I don't have anyone in that box. Not one, so there's nothing to worry about. The relationship between my box and that place is probably like a car, a tent. So, don't worry. Lin Ji comforted the mushroom pickers.

Picking mushrooms is indeed a little panicked. There is such a person as Lin Ji in this world, and the world has been turned upside down, if there are seven billion, she doesn't know what will happen to this world.

After being appeased, Cai Fu was still a little persistent: "Seven billion, how much is that?" ”

"As a rough estimate, the population of our planet is now 10 million. Of course, they live too far apart, and even if we go out to look for them, we may not be able to find so many. You see, we have only 500,000 people in China now, and the area occupied is actually not small. For 500,000 people in that place, you can probably live in Hong'an County. Some places are densely populated, and you may not live in a place that is as big as Chaolin City, or even smaller......"

Cai Fu had a long mouth: "That means we can all live in Chaolin City?" ”

"If there were people out there farming, it would be about the same."

Dreaming up like that, he asked, "Can we do the same?" ”

Lin Ji said: "What I am doing now is to take this path. ”

"We don't have that many of us."

Lin Ji said: "I thought about it for a while, if we can develop, we may not need such a large population. Although in some cases, the more people you have, the more wealth and wisdom you can gather, I think that in the current situation, we should not have so many people. ”

At present, the development of China is different from the development process of mankind.

In the development of nature, human beings need to carry out a lot of exploration before they can make small breakthroughs in some aspects.

From the perspective of the post-industrial revolution, science and technology are undoubtedly the primary productive forces. But before this realization, technology was called witchcraft in Western countries. The East regards science and technology as a strange and ingenious technique, and does not attach importance to it.

This process of cognition lasted for thousands of years.

Even with this understanding, human beings still need a lot of experimentation and exploration. It is possible to achieve scientific and technological achievements one by one. Some major scientific and technological achievements may require the collective investment of the entire country or even the whole world before there can be a breakthrough.

But here in the forest trails, groping is basically non-existent. Or rather, the goal is clear.

He knows all kinds of basic physical, chemical, and biological basic laws. There are samples of various industrial products for you to copy. We also know what the future holds.

This can avoid detours in the development process, and can also reduce a lot of unnecessary investment.

Moreover, in the case of clear objectives, the research period can also be greatly reduced. For example, the Manhattan Project in the United States took seven years to build an atomic bomb. However, China only took two years to build an atomic bomb when it was far behind in technology and equipment. One of the important reasons for this is that the United States still had to find out whether it could build an atomic bomb at that time. And we know that the atomic bomb can be made. Because the United States has already made it.

Therefore, under the condition that the forest trail can be guided, at least until the completion of the industrial revolution, there will definitely be no need for such a large population in later generations.

This is also the reason why Lin Rui is willing to give up a part of the space to maintain the ecological environment.

If his attempt can be successful, or humanity will move in a new direction.

"When I go back, I'm probably going to start preparing for university, and I'll have experienced craftsmen become professors. Middle schools have been established in the county. Let the bright children study the knowledge. All go to college. Then I will marry you, and then I will let all the children go to elementary school, and let them go to school for at least six years. When will our population reach two million......"

Lin Ji casually talked about his plan, and Cai Fu didn't know when he fell asleep.

After dawn, dew drops dripping from the leaves, and the forest trails carefully wait for the mushroom picking, which is difficult to move freely.

For the next few days, the two of them were glued to each other in the forest. Perhaps it was because Cai Rong heard Lin Ji's promise in his sleep, and behaved more decently in the following days. It's just that she was afraid of Lin Ji's endless demands, and suggested that Lin Ji finish building the half of the wooden flute house.

Lin Ji sympathized with her as a bride, and she was also kind as a stream. So the two of them added two snow monsters, and then pulled the white horse as coolies, and carefully decorated the hut.

A few days later, the house was built, and the mushrooms sprinkled a handful of pepper seeds in front of the house, and soon they found themselves welcoming a guest.
