Xiaocao motioned with her eyes for me to go to the farm behind me. I took the bowl and walked towards the kitchen on the farm, and Xiaocao followed up and whispered, "Once again, I tell you not to let Xiaomi know that I have learned modern Chinese, and to keep us in a state where we can't communicate." ”

"Good! I remembered. But does he know about the two of us last night? ”

"It doesn't matter what happens to the two of us, that's normal and as it should be." Xiaocao said lightly.

"The Celestial Spheres are weird," I shook my head, then nodded, and for them (not biological people) should and are normal. I walked out of the farm and back to my room.

Xiaomi has attached the terrestrial suit to the counterpart of the house. Seeing me coming, Xiaomi pressed the switch and opened the isolation door between the earth suit and the room. After I walked into the earth suit and put it on, Xiaomi disconnected the earth suit from the house. I looked back and saw that the grass had also walked out of the house.

Today's weather is so nice, the sky is clear, the sky is high and the clouds are light. "Our latitude is the autumn of the celestial sphere, right?" I asked Xiaomi.

"Yes, it is equivalent to the autumn of the earth, and now the autumn is high and cool. However, the cloudy weather and rain and snow are controlled by the celestial spheres. For example, when there is a shortage of water, it rains there, and where the wind is needed, it blows. ”

"Wind, rain, frost and snow, you will also control it? You don't have any need for agriculture, transportation, etc.? What is the use of climate control? ”

"Yes, we don't have to serve the needs of agriculture, transportation, etc. But we have to make it rain for the waterfalls and rivers that lack water, and the icebergs that melt and snow. That's why the weather is controlled. ”

We chatted and walked, and the flowers and trees under our feet were the same as what we had seen before. "Let's go to the strange place of the celestial sphere!" I recommend Xiaomi.

"Okay, don't waste time here" Xiaomi and Xiaocao stopped me left and right. With a whistle blowing into the air, I only heard the gust of wind in my ears. After a while, they slowly lowered me to the ground. When I opened my eyes, I saw a glass house in front of me.

"This is the Celestial Sphere Fertility Center. Didn't you ask me how the celestial sphere can continue with only men? This is where the Celestial Orbs begin. ”

"How does this work?"

"First of all, the person of the Heavenly Sphere (to be precise, the man of the Heavenly Sphere), once he reaches the age of eighteen, he must have a physical examination on his own and send all the data of his body to the Celestial Sphere Information Center. The Tianqiu Information Center selects the best people in various indicators among all the Tianqiu youths and enters the preparation team of the Tianqiu Fertility Center. If there is a shortage of celestial sphere people, no more than three groups of cells will be extracted from these people, and they will be multiplied and cultivated, and after a year, they will be cultivated into a celestial child. ”

"This is a clone, right? Can parthenosexual clones be healthy? I asked Xiaomi.

"Yes. Now the technology of cloning the Celestial Spheres is very mature. The chromosomes of celestial spheres and earthlings are not the same. A pair of chromosomes of a celestial man is YY, and when the celestial sphere originally had a woman, their chromosomes were XY. Later, the celestial species became extinct, the celestial woman ceased to exist, and the X chromosome disappeared. The Celestial Sphere people can only be passed down from generation to generation by men, and it has been passed down to the present. ”

"Oh! So that's it! I exclaimed.

We walked between the two glass houses and saw that there were many children with celestial spheres more than one meter tall playing various games in the houses on both sides. From time to time, one or two adult men play with the children. Occasionally, a woman made by the Celestial Sphere comes to take care of the children. Millet pointed to the smaller children in the house on the left and said, "This group is the youngest child in the pregnancy center. ”

As we walked on, the children in the glass house were getting bigger, taller, and playing more and more complex games. Pointing to the last house, Millet said, "This is the oldest child in the pregnancy center, ready to be adopted by an adult." They can leave the gestation center and live in the vast celestial world. ”

"Anyone can adopt?"

"Children between the ages of 25 and 45 can be adopted on the celestial sphere. After adoption, continue to let the child learn the language of the celestial sphere, improve their self-care ability, and protect and take care of them. ”

"Is this the family planning of the celestial sphere?"

"That's right! There is a certain number of people born each year, and none of them can be changed. We have more than 10,000 fertility centers, each of which produces nearly 100,000 celestial spheres every year. If you go like this, it will take too long. Every glass house here is much the same, after visiting a glass house. Shall we run to the next attraction? I nodded in agreement.

We walked out of the gestation center and flew to the next stop. After flying for a while, we arrived at the Celestial Sphere History Park. Unlike the incubation center, this is an open park. The park is arranged in the order of the history of the celestial sphere, and the first part is the beginning of the human history of the celestial sphere, which is equivalent to the primitive society on the earth. The Celestial Spheres also lived in caves and crypts at the earliest. We walked along a path that was like that used to be taken by primitive people, and there were no houses or crops on either side of the road. Occasionally, I met a few creatures that were very similar to primitive people on the earth, and Xiaomi said: This is the primitive man of the celestial sphere (it is now made by the celestial sphere, and the same is true for the historical figures behind, so I will not repeat it) We have primitive murals as evidence. These primitive people were dressed in animal skins and leaves, and some of them seemed to be hunting, while others were gathering wild fruits. These primitive people turned a blind eye to our arrival. There is nothing modern about it here, very similar to their current celestial sphere.

Going further, we entered another historical era of the celestial sphere. The Celestial Sphere people here live in a self-sufficient agrarian society, just like the ancients on earth. The basic streets have been formed, and the houses on both sides of the street are of high and low heights. People walk through the streets in homemade homespun clothes. Some are like small merchants and hawkers, some are like rich businessmen, and some are like dignitaries. Equally indifferent to our arrival.

The place was so big that we talked as we walked, and I walked slower in my earth suit, drinking water, eating, and sometimes making it convenient. When Millet and Xiaocao were in a hurry, they dragged me and ran like flying, otherwise they didn't know when they would go for hundreds of kilometers in each section.

Millet and Xiaocao stopped. Xiaomi pointed to a high-rise building in front of him and said, "This is another section, go in and have a look." I rubbed my eyes and exclaimed, "You're sending me back to Earth." I saw a forest of high-rise buildings in front of me, wide roads, and all kinds of cars speeding away. Airplanes roared in the sky, and trains raced on the tracks.

"Nope! This is also a period in the history of the celestial sphere thousands of years ago. ”

"Isn't this the Earth now? Could it be that thousands of years ago the celestial sphere was the same as the earth we have now? I asked Xiaomi suspiciously.

"Yes, at that time, the celestial sphere was very much like the earth today. The Celestial Sphere people thought that they had entered a highly developed modern civilized society. began to enjoy life wantonly, and consumed a large amount of resources in order to satisfy material desires. For the sake of people's selfish desires, they will encroach on the living space of other creatures at will. Later, although the Celestial Spheres realized the seriousness of the problem, it was too late. No matter how hard we try, we can't stop the extinction of species even if we pay a hundred, tens of thousands. In the end, only one creature remained, a human being, or half a creature, a man. ”

"You told me about this process before, and you told me again today in conjunction with the visit to the Tianqiu Historical Garden. It seems that this process has deeply pierced the hearts of the Celestial Sphere people. However, this process cannot be reversed, so what is the point of building a historical garden? ”

"One is to remind aliens like you to be a guest on the celestial sphere to always be vigilant against changes in the ecology. Another reminder to the Celestial Sphere people not to make a decision to change the ecological environment of another planet lightly, that will not improve the civilization level of the universe. ”

"It seems that we earthlings have to learn these lessons, and we don't know if it's too late?" I don't worry about muttering to myself.

"It seems to me that it is very difficult to change the outcome. But from now on, it is urgent to change the ecological consciousness of people on the earth, and perhaps it can also delay the rate of extinction. Ecology is a whole system, and when we exterminate a pest with chemical agents, we are cutting off more than one food for the beneficial insects that feed on it. This is equivalent to destroying more than two creatures. In fact, pests and beneficial insects are just a kind of creature relative to us humans. Only by living things can they continue to live and restrain each other. Otherwise, the Earth will soon become the next celestial sphere. There is only one species, or half a species, left - the woman. ”

"Why? Why is there only a woman left on earth in the end? "I suspect it's a conspiracy by the Celestial Spheres. So he asked.
