Humans became extinct after returning to Earth [Infrastructure]

Since the beginning of winter, eight out of ten days outside are windy days.However, according to the forecast, the wind and snow will stop for another two days, and there will be a rare sunny day outside.

Since hearing the news, Luo Guiting has been building a sled.It doesn't have to be too delicate, just enough to seat three people.

When Luo Guiting was training before, he learned how to do simple sleds in extreme environments to reduce his own weight and carry more things.So it's not that hard to do.And the bamboo itself can slide on the snow without much processing.As long as the front end is heated with bamboo charcoal, the front end of the bamboo can be bent upwards to have an arc suitable for moving forward in the snow.

After several adjustments in two days, it was handed over to Wencheng to install the engine.

They did have two dogs, but they were not big enough to pull a cart. Besides, it was not clear what happened to the snow above, and the dogs might sink right into it.But sleds can use artificial rubber to increase the contact area, thereby enhancing buoyancy.

After the snow stopped and the clouds cleared, the three of them set off directly on the second floor, went out from the second floor, laid some bamboo on the snow to prevent it from sinking, and pulled the sled onto the snow with a rope.

Under the heavy snow cover, except for the tall trees that protrude, most of them are flat snow fields that can be seen all the way.

Luo Guiting's glasses automatically changed to the sunglasses mode, looking back Luo Qi had already put on special glasses.

Luo Guiting grinned at Luo Qi: "Come on, let's go for a drive!"

The engine started, the sled kicked up snow dust on the snow, and there was a lot of laughter on the snow.

It's going up the mountain and drifting again. It's a lot of fun for a few people to play.Finally, when I went up to the hill and looked towards the sea, there was already a lot of ice freezing on the seashore. Although the seawater in the distance hadn't frozen yet, judging from the current situation, it was not far from freezing.

This should be the hottest place.

If it is said that it is the North and South Poles, Luo Guiting will not be surprised at all, and even feel that winter is too late.

What a shock it would be if all the water in the world froze.

What about tides?Even the tides are affected?

Luo Qi interrupted Luo Guiting's thoughts in a timely manner: "When the sea freezes, will we not be able to catch fish?"

They have prepared enough fish for a whole winter, but the processed seafood is definitely not fresher and more delicious.

Luo Guiting shook his head: "If the ice surface is solid, we can open the ice surface and lower the net. After the ice freezes, the underwater oxygen is insufficient, and the fish will gather if we open our mouth. There are more troublesome ones, which can be deployed underwater. Fishing from the net. It’s actually quite fun.”

In Luo Guiting’s memory, in Northeast China in the 21st century, there was a very exciting and interesting underwater fishing method. A punch hole and a large circle of small holes were punched on the ice, and the fishing nets were shuttled through it like a needle and thread to form a large picture. The back of the net is pulled out in the main hole.

They are not that big of a network, and they don't have that much artificial cooperation.However, it is not difficult for two strangers in the 45th century to let the machine carry the fishing net into the lower end and fish for a circle.

They use bamboo tubes to fill hot water, wrap it in natural rubber and hide it in their clothes, so they can drink hot water at any time, and keep warm when they are not drinking.

Wen Cheng took a sip of the still hot water, and only sighed: "Although I know the principle, I still find it unbelievable. The leaves are falling off bit by bit, the snow covers the earth, and the world is barren and there is only one white day. When the spring comes next year, the ice and snow will melt , Flowers and plants will emerge from the land again, and trees will flourish again."

Luo Guiting couldn't help laughing after hearing such a perfect score composition.

"That's why lives overlap and time flies?"

Wen Cheng held his chin: "I just think it's meaningful. Fallen leaves will always grow, and ice and snow will always melt. This kind of change is an endless cycle. Countless spheres in the universe are barren, and they still don't affect the Almost eternal life."

This is too philosophical.

Luo Guiting knew it was useless to think about it, but when Wen Cheng talked about it, he couldn't help but feel depressed.

He was right, since everything is destined to be meaningless, what is the meaning of everything?

Luo Qi obviously has a different opinion.

"Do you like fried fish steak?" Luo Qi asked Wencheng.

Wen Cheng blinked: "I like it!"

"But the fish fillet is only good when it is freshly fried, and it will not be crispy when it cools. Or, as long as you don't eat it, it will definitely become unpalatable. Then you will because it is destined to become Is it unpalatable and hate it?"

Wen Cheng shook his head half understanding.

Luo Qi smiled and said, "You cherish it when it's delicious, and try to eat it while it's still delicious."

Wen Cheng came to a sudden: "So those changes also make sense."

Luo Guiting glanced at Luo Qi and smiled: "Because the ice and snow are destined to melt, the snow scenes you see every year are different. You shouldn't lament that the ice and snow are destined to melt, but cherish every sight you see while you are still there." At a glance. Flowers are doomed to decline, so you should appreciate them while they are still there. Changes are beautiful because you know how to appreciate them.”

In fact, Luo Qi himself had pessimistic thoughts, but after he walked out of that safe cage, everything was different.

Wen was stunned, as if he had thought of something.Luo Guiting didn't talk to Luo Qi any more, and gave him enough time to think about these things.

After all, Wen Cheng is pessimistic about the future, and he always feels that they are destined to be in danger in the future.

But I never thought that with the uncertainty of the official future, the present comfort is so precious.

The weather was fine for two days.The three of them ran around in the snow on a sled.When Luo Guiting was free, he would deliberately use an iron basin to freeze some round ice instead of a snow table.The translucent table with air bubbles is placed there, and the ingredients are placed on it, which can not only refrigerate the ingredients, but also look good.

After the ice table was ready, Luo Guiting became addicted to it.Started to change the way of research to make some ice furniture.Even ice lanterns.

The ice lamp is simple, just pour water into the cup, freeze it for a few hours, let it freeze on the outside, when the inside is still water, take out the ice, cut a hole in it, and then put a small table lamp made of grease on the small table lamp. On the plate, stuffed into the ice lamp, the weak light comes out from the transparent ice lamp, which has a special taste.

Some small candlesticks were dug out on both sides of the snow cave. When walking through at night, the faint lighting on both sides is very beautiful.

Even if they knew that everything would be gone when the flowers bloomed in spring, the few people just couldn't get tired of it at this moment.

After the catastrophe, it is difficult to see other lights at night on the earth except the brilliance of the moon, especially in winter.That's why Luo Qi especially likes shiny things at night. After finding that he was always staring at the ice lanterns in a daze and couldn't move his eyes, Luo Guiting also thought about making more beautiful ice lanterns, or even ice sculptures, using small LED lights as light sources.

Luo Guiting wants to satisfy Luo Qi's preferences as much as possible in his spare time, while the little pig looks like it's full moon, and the little sheep is about to give birth.

Luo Qi held his face and looked at the lamb in the artificial womb. At this time, the lamb inside had opened his eyes and was looking outside through the translucent womb.It looks a bit weird, but the lamb's eyes are clean and clear, which is quite beautiful.

"How long after this is born?" Luo Qi asked, frowning.

Although the piglets born last time have grown a lot, they can still be slaughtered for a longer time than what Luo Guiting said.

"Longer than piglets, and isn't it mating?"

Luo Qi curled his lips, "It will take a long time. There are only six lambs, and they have to be bred. Even if they can be eaten, they can only eat one or two at most."

Then wait for conception, birth, and raising, and wait for a long time.Mutton freedom cannot be realized at all.Wait at least two or three years, or even longer.

Luo Guiting couldn't help laughing: "Do you have to let the ewe go to give birth?"

Luo Qi twitched the corners of her lips in embarrassment.After all, he is a person of the 21st century, so he let Luo Guiting, an old man, teach him these things.

After these little guys are sexually mature, they can directly extract a large number of egg cells and sperm cells, and then the artificial uterus will undertake the breeding process.So in theory.Within a year they were free to eat meat.

Now only a few can be bred, mainly because there are really not many frozen fertilized eggs, and there is loss in the breeding process, they can't bear too much loss, after all, if they are gone, they will really be gone.

But if there are adult animals, as long as they can be extracted, they will be inexhaustible.

Luo Guiting was not willing to embarrass him, and put his arm around his shoulders: "It is beautiful to be born naturally, but we have no time to appreciate so much when we are waiting to eat meat. It's just that lambs need more than half a year to breed. But after we have hundreds of lambs successfully conceived, one of the six lambs will not be kept, how about it?"

Luo Qi took advantage of his relief and thought about it seriously: "Let's keep a male and a female."

Natural reproduction also leaves a little behind.

Luo Guiting knew what he was thinking, and said, "Then let's keep them in the grove."

"You can stock them all."

"Listen to you, the meat that is spread all over the mountain is delicious." Luo Guiting thought that he could consider raising some chickens in the coming year.It's just that only the small forest can be used here, and there are mutated ants in the forest.Even if the number drops sharply, it will pose a great threat to the survival and reproduction of chickens.Unless it is free-range, I don't plan to catch it back and eat it. Otherwise, if I send it to the forest, I have to be prepared that there will be no one left.

The lamb is just close to giving birth, but according to the system's calculations, it will take two days.Today, I don't know if the two dads have been observing for too long. A lamb stared at the two intently and struggled to get out.

After hearing the system prompt, the two hurriedly ended the topic and notified Wen Cheng to observe the delivery situation.

After Wen Cheng came, he upgraded the machine inside a second time, so almost no manual movements were needed, just watching the show was fine.

Herbivores are different from carnivores or omnivores. The moment the afterbirth falls, the limbs are trying to stand up.After the hair on his body dries naturally, he can already walk unsteadily.

Looking at the little guy who was working hard to eat milk, Luo Guiting couldn't hold back, and reached into the incubator to pet the lamb.The lamb was still eating the nutrient solution hard, but looked at Luo Guiting without blinking, helpless and dependent.

For a moment, Luo Guiting couldn't even imagine that this little guy was his future food.

Perhaps this is the biggest charm of the cub, which makes people unable to feel the slightest urge to hurt.

Luo Guiting rubbed the lamb and couldn't help but glance at Luo Qi.

Luo Qi blinked, thinking about touching them together.

Luo Guiting just arrived: "Let's have a baby too."
