Humans became extinct after returning to Earth [Infrastructure]

The sun was in the sky, but the thin clouds in the sky cast a shadow from time to time, so it wasn't too hot and uncomfortable.

Luo Guiting handled the fish neatly, and handed over the excess to Luo Qi for refrigeration, and marinated the rest and roasted them on the fire.Luo Qi handed over a glass of ice water, and the two of them felt comfortable listening to the sea breeze blowing and the waves churning.

Looking down at the ice water, there were two square cherries in it.This was Luo Guiting's idea. Pick out the core, mash the pulp and put it in a mold to freeze into ice, so that when you drink water, throw it in. As the ice melts, the juice pulp slowly melts into the water, and the taste It's very light, but it's still much happier than drinking plain water.

"There's still too little fish." Luo Qi smelled the smell of fish floating over.

Luo Guiting enjoyed the heat of the sun on his body, squinted his eyes and thought for a while: "I can't catch fish now, but there is a way worth trying."

Luo Qi raised his eyebrows, Luo Guiting smiled and said, "Tell me, do many fish pass by that cracked trench every day?"

On the side of the forest road, there is a crack tens of meters wide, and below it is a [-]-meter cliff.

Luo Qi frowned and said, "It's too wide."

"So we need a big net with strong load-bearing capacity." Luo Guiting thought about it, and said: "Actually, it doesn't need to be too big, as long as it can catch fish up and down at any time, it will be easy to receive the goods." would be too little."

Luo Qi didn't understand these things, so he didn't speak.

The fish received this time is enough for a few days, but it is impossible to prepare for the future.

Luo Guiting was not in a hurry either.After eating, I put out the fire with sea water, and after a while, I found sand that met the requirements and dug some to bring it back.

Looking back, the stove was already half-dried. Luo Guiting cut two thick branches and made them into brick molds. After pressing the rough clay into the molds, he sprinkled some plant ash on the building. Place the adobe on it to dry in the shade.

It will take a few days to dry in the shade, so just be busy with other things during this period.

Such as collecting iron ore and coal.

The iron mine is okay, it is an open-pit mine on the mountain in the east of the island, and it can be mined whenever it is needed.But on the other side of the east mountain is a cliff that has never been visited.And the coal they want can only be found after going down the cliff.

In just 500 years, the earth has undergone drastic crustal changes, and the land has been divided and reorganized. In many places, the original mineral veins have been destroyed under severe compression.

However, it is indeed a miracle that this island can have such rich mineral resources.

Luo Guiting didn't have a decent manuscript, so it was obviously unrealistic to use a stone pick.So the first piece of iron ore was collected by smashing it with a laser gun.When Luo Guiting was free, he wove small baskets out of tree branches. After collecting a basket full of iron ore, the coal mine had to be disposed of.Otherwise, you can only burn charcoal when smelting.Wood is absolutely not up to the height required for smelting.

But if you burn charcoal yourself, it is not an easy task to achieve the required amount.

The only good thing is that there is a refining machine in the refuge under the cliff, and Luo Guiting only needs to smelt the ore into shape.The following work can continue with high-tech equipment.The more detailed ones are in Luo Qi's care.

The two have a clear division of labor.

Arriving at the edge of the cliff on the other side of the mountain to the east, Luo Guiting looked at the wind and sand on the cliff and was worried.Not to mention the trees, even the larger stones are invisible, and there is no place to tie the rope, so it is not easy to go down.

Luo Guiting stood on the edge of the cliff and looked down. The cliff continued to go straight up and down, and one glance made one's legs tremble.

"It's really not possible... Let's build a stake on it." Luo Guiting stood on the cliff and looked down with some embarrassment.

After Luo Guiting finished speaking, he didn't hear a response for a long time. He probed into the tablet and saw Luo Qi was gesturing with his mechanical hand.

"You still want to be a hero?" Luo Guiting laughed.

Luo Qi rolled his eyes at Luo Guiting, and said: "You are too heavy, go down and take risks."

The trees are fine, but what if the piles are not stable?

"Then what do you mean?"

Luo Qi stretched out his mechanical hand and directly took out the laser gun pinned to Luo Guiting's waist: "I'll take this down."

Luo Guiting is very heavy, it is not safe to go down, and Luo Qi is limited in what he can do.But Luo Qi's weight in the outside world is only the weight of this tablet, and Luo Guiting hooked it up with a flick of his little finger.What's more important is that Luo Qi doesn't have to carry heavy burdens, and the collected ore is taken directly to him.

Where did Luo Guiting disagree?Busy research to fix the tablet with a rope.

"Don't cover too much, it's not convenient for mining." Luo Qi reminded.

"What if I don't fall down safely?" Luo Guiting would rather save some coal mines than say goodbye to Luo Qi.

Luo Qi also understood this truth, and it was really embarrassing.

In the end, Luo Guiting disassembled a rope and wrapped it around the four corners of the plate to fix it separately. Although it still took up a lot of space, the middle piece was kept as much as possible.

When it was fixed, Luo Guiting shook it dozens of times in a safe place to make sure that it would not fall off. Then he stood on the edge of the cliff according to the mineral veins marked by Luo Qi, and carefully put Luo Qi down.

Don't worry about anything else.Luo Qi will transmit the news in real time.Luo Guiting looked at the picture transmitted in his eyes, and felt a little relieved.

"Probably this is the location, I just need to dig a little way inside. You can try the laser. If it doesn't work, use my laser gun. You don't need to dig too much at once, as long as you have some samples to confirm that it works. Let's not worry." Luo Guiting disagreed Forgot to ask.

Luo Qi didn't respond, but in the screen he has already started mining.

Luo Guiting tied the rope around his wrist, and watched Luo Qi mining under the sun.

Just when he was drowsy, he finally saw the dark and shiny coals on the other side.

"The flammable content is very high, so it should be qualified." Luo Qi transmitted his test results to Luo Guiting, and Luo Guiting used his eyes for a second test.

"Okay, you can bring out a part and I'll pull you up!"

Luo Qi didn't try his best either.After digging more than ten catties of coal, it came out.It is said to be more than ten catties, but in fact it is not much. If it is placed in a basket, it will not even cover the bottom.However, this thing carried all the hopes of their subsequent smelting.

Luo Guiting didn't care about it, and held a piece of coal to look at the sun: "It's enough to have this. Let's burn the bricks today. It happens to rain tomorrow afternoon, so there is time to cool down."

"What about the two days when it rained?" Luo Qi asked.

"Let's weave fishing nets." Luo Guiting's plan was thoughtful.

Fired bricks are just rough bricks and don't require too high a temperature.So sun-dried bamboo will do.It was past three o'clock in the afternoon when we went back. Luo Guiting neatly stacked the dry bricks in the earthen kiln and lit them on fire. Put it on a little bit for ventilation, and just burn the fire behind it.

Because it is a rough brick, it does not need to be too detailed.By the way, Luo Guiting cooked a pot of fish soup on it for dinner, and after eating and cleaning up, the fire can be stopped.

It was less than three hours before and after.Don't move for the rest of the time, go back to the escape cabin to sleep, and start the kiln the next morning.

A lot of bricks are needed to build a qualified smelting furnace, of course one furnace is not enough.Luo Guiting opened the lid, and picked up the top brick, which was still a bit warm, and its color was already a dark brick red.A little jingle on tap, good quality and good sound.

Only 24 bricks were fired from this first furnace.Two of them were cracked, but still usable.Put it neatly in the corner of the building, and pour some cold water on it to prevent cracking.Luo Guiting placed a second batch of bricks in the furnace to continue firing.Breakfast was resolved during the period.Luo Guiting took the bottles and cans from the building, and looked for rubber trees in the small forest. After cutting the opening with a knife, he used bamboo pieces to connect the rubber to the bottle.The bottle is fixed to the tree.

When it rained in the afternoon, Luo Guiting came to collect again, and he collected a whole bucket.

It happened that they had saved a lot of formic acid. They put the formic acid into the rubber and stirred it for a while until it solidified into a tofu-like shape, and then pressed it into tablets to shape it.After setting the shape, wash off the formic acid on the top and hang it in the building to dry.Listening to the sound of rain outside, the day's work is over.

The production of natural rubber is one of the earliest processes that humans mastered, mainly because of its simple processing, and rubber itself is a material with a wide range of uses.

The first thing Luo Guiting has to do is to make a protective case for the tablet first, so that it will be more convenient to put the tablet under the cliff in the future without fear of it falling.

Anything else would be easy.Fortunately, the machine can assist in the secondary processing. As long as the raw materials are made, the follow-up does not need to be too troublesome.

In ancient times, the raw materials were simple and the fine processing was troublesome, but it was the opposite when it came to Luo Guiting and his wife.They never worry about finishing, and the raw materials cost them a lot of effort.

When the rain was lighter, the two of them went back to the escape cabin first.

In the past few days, Luo Guiting has been very busy, and Luo Guiting just touches the pillow almost every day.When I came back today, it rained, and my body was a little cold, but I was a little more energetic.

Lying in the escape pod after washing up, tossing and turning unable to fall asleep, I looked over to Luo Qi, who was lying on the table, wondering what he was thinking.

"Have you always been this boring before?" Luo Guiting couldn't help asking.

The two have been together for such a long time, and they hardly see him playing games or having other hobbies.If you want to say what you like, most of them have to eat.

"It's okay." Luo Qi didn't feel it himself.

Luo Guiting couldn't help teasing: "So desireless? Then the girl who likes you is probably going to cry."

Luo Qi was startled: "Why do you like me?"

"You are quite rare." This is the truth.

Luo Qi was silent for a while, and said, "The 45th century is not as romantic as the 21st century."

"They're all like you?" Luo Guiting didn't quite understand, "Humans are also animals that have a strong need for companionship."

"I have you with me."

"...Did you completely ignore your physical needs at that time?" Luo Guiting didn't have a chance to find a partner before, because he was always busy, and he didn't have a chance to enter the Air Force Academy.

Whenever there is an opportunity, who would not want to hold a soft warm blanket in their arms?

Thinking that there is someone next to the pillow, it should be quite a sense of security.

In fact, Luo Guiting also regretted it when he said it.After all, even in the 21st century, there are many people who like someone.Luo Guiting was simply used to being lively since he was a child.

Luo Qi looked at Luo Guiting with a puzzled face, and when Luo Guiting wanted to make amends, Luo Qi's words almost made Luo Guiting choke.

"Don't you have any tools?"

"..." Luo Guiting was ashamed.

Luo Qi turned around and rummaged for a while: "Why don't you lend me mine."

"...Do you want to share your experiences with me?"
