Humans became extinct after returning to Earth [Infrastructure]

Luo Guiting had no experience in smelting for the first time.Just simply burn the furnace to the melting point of the metal.After cooling for one night, I opened the lid and found that the bricks in the furnace had melted, which shows that the previous temperature was high.

Take out all the ashes and slag from the furnace below and spread them on the ground.Luo Guiting just squatted on the ground and fiddled with him bit by bit.It feels like panning for gold, whether you are poor or rich, you can see it all.

These slags did not disappoint Luo Guiting, and soon saw traces of metal reflection attached to a piece of cinder that had been burnt with a big fist.

This is pig iron the size of a fingernail, the roughest iron.

But that means they succeeded.

Turn on the eye search function, and jump out of the burnt pig iron bit by bit.The big ones are like eggs, and the small ones are smaller than rice grains.Thanks to having eyes, iron sand can't escape Luo Guiting's palm.A large plate of pig iron was quickly picked up.

These pig irons are very poor in shape and color.But putting this state into the machine is enough for further refining and forging.

Not to mention that machines can be forged, if Luo Guiting is given a big hammer now, he can smash out the impurities inside and forge some guys with one hammer at a time.

This is the first step in forging, but for Luo Guiting, who survived on a deserted island, it is tantamount to an epic step.

The remaining cinders were not thrown away, but piled in a corner outside the building. Luo Guiting refilled the furnace with coal and then placed rough stones. This primitive smelting method is completely feasible at least for now.

When the flame was lit again, Luo Qi fiddled with the first furnace of pig iron, and said, "We should consider copper."

Brass is more stable than iron and can do more things.

Luo Guiting thought about it: "At least make a shovel or a pick before thinking about it."

The brass is in the ground, although it is not very deep, but it is necessary to dig a mine.If there are no tools made of iron, it is absolutely impossible to rely on stone alone.This is not playing games, it is hard to say anything without ironware.

"What's that?" Luo Qi obviously hadn't seen it before.

There is no model in Luo Guiting's system, so he drew one on the ground: "This part can be made of wood or bamboo, but a lot of heavy iron must be used in front. Well...at least two to three catties, the more the better. "

"This furnace is eight taels." Luo Qi said.

It is not enough to make a catty of utensils with pig iron to build a farmhouse. The magazines are extracted and then forged and polished. In order to avoid shortage of two tools, at least ten catties of pig iron are needed.

That is to say, it takes more than ten furnaces to burn out the iron needed.

Thinking of this, Luo Guiting's head couldn't help but grow bigger.

"Let's make more stoves. Let's make a clay stove first, and burn bricks together with the two clay stoves to continue. Try to make it within ten days, it shouldn't be difficult."

This furnace can be smelted once a day at most. It is not difficult to smelt ten catties of iron within ten days, and building a few more smelting furnaces can be used for a long time in the future, which is worth the trouble.

Luo Guiting usually decides this kind of thing. He consulted with Luo Qi, and Luo Qi never raised any opinions.

In order to obtain brass as soon as possible, Luo Guiting repeatedly dug clay during this period, made a second clay oven, and then made bricks.It just takes a few days to dry.That can only wait impatiently.

The broken bricks left over from the previous firing are smashed and mixed into the clay to make clinker, which can reduce the probability of the finished product breaking.

On the other side of the brick furnace, the iron was continuously burning, and as the finished products came out, a lot of pig iron slag was collected.

The fish that was dried before has become dry.Pick up the phone and stuff it into the escape cabin, and set a room inside as a vacuum. After the dried fish is put in, several households don't have to worry about deterioration.As for winter, you can think about it. Anyway, if you want to move out, you just need to stuff it into Luo Qi's side, and you don't need to go back and forth.

And the fish that were marinated earlier were also dried in the sun.The island is rainy and sunny.Very precious on sunny days.

While drying, light a smoky fire below, but it doesn't need to be smoked too well, but the taste of more smoke can greatly extend the shelf life.

After the bricks were finished drying and the two clay ovens were fired at the same time, Luo Guiting became more relaxed.

During the period, I went to the bridge to catch fish twice, and the two ate fish more and more frequently. No matter how delicious they were, Luo Qi was tired of eating them.

Seeing that his meals were not as turbulent as before, Luo Guiting took the time to go up the mountain and beat a big rabbit weighing nearly ten catties down.The two of them ate this fat rabbit for two full meals, and Luo Qi, who was eating fish and smelling like fish, saw the shivering rabbits grazing in the building with bright eyes.

"The chick has already formed, and it shouldn't be long before it will come out." Luo Guiting counted the time, the chick has been in the fetus for half a month, and it will normally take another seven or eight days to break out of its shell.

It's about time when shovels and pickaxes are made to start digging holes.

"You can't eat it even if you come out." Luo Qi stretched out his hand and grabbed a piece of grass to tease the little rabbit to eat it.

The two-month-old rabbit is almost two catties.But it's still a bit extravagant to eat now.

"Actually, if you want to eat it, you can eat it in a month and a half. It's just that we have to keep the raw chicken and eggs. It will take more than half a year to eat it. But we can eat some useless roosters."

"Useless cock?"

"It's enough to save one or two roosters for breeding, and it's a waste of food to keep the rest. Hens that can lay eggs are all treasures. If you want to be greedy, let's kill a few more roosters to eat." Luo Guiting explained.

Luo Qi pondered for a moment, then said, "Among livestock, are males so useless?"

Luo Guiting was about to say yes before he realized it, and said, "That's why I said it was a livestock. We are different."

Luo Qi did understand, but looked at Luo Guiting with a somewhat weird gaze. Although he knew it was impossible, he still had the illusion that he was a "useless male".

The two of them looked at each other awkwardly for a while, and Luo Guiting went out to see how the stove was cooling.

After the second brick oven was built, it became apparent that coal was not enough.

In addition to smelting, the next two days were dedicated to digging charcoal.Until a hill piled up in the coal room.

In order to comfort the hardworking Luo Qi, Luo Guiting extravagantly killed a little male rabbit, cut it into pieces and stewed it.

Different from the test results, the delicious and tender rabbit meat comforted Luo Qi's stomach, and made his eyes on the rabbits more explicit in the next few days.

Luo Guiting said earlier that it was within ten days, maybe because he knew too much about his own abilities, maybe he was a real prophet, and on the tenth day, he just smelted twelve catties of pig iron.

The stove continued to burn, and Luo Guiting and Luo Qi started modeling and discussing what it would look like.

No matter how much Luo Guiting knows, he is no blacksmith, and what he can do is quite limited.Fortunately, you don't need to forge the iron yourself, just discuss the shape.

"It still needs to be thick enough to be corrosion-resistant. It will be good to dig more in the future. If conditions allow steelmaking to make steel tools, it will be more durable."

Luo Qi raised his eyes: "That's directly automated."

Luo Guiting couldn't help twitching the corners of his lips when he heard that, that's right, everyone has the ability to make steel, so the industrialization should be quite high.At that time, both mining and smelting will be mechanized and automatic. Where do you need to dig by yourself with steel farm tools?

This is tantamount to the ancient people guessing that the emperor used a golden hoe to shovel the ground.

"At least dig out the brass first." Luo Guiting looked at the dense clouds in the sky again, and couldn't help frowning, "I've been back for more than a month."

"almost."

"It really likes rain." Luo Guiting complained, then turned and went to the field.

When he was free during this period, he reclaimed another piece of land, and the seeds he planted were only a small bud tip.And the land in front is already quite impressive, and the green Yanran is similar to the vegetable field before the end of the world.

Except for leafy vegetables, most of the food is still inedible. Maybe Luo Qi's foodie spirit is too strong. Luo Guiting is reluctant to tell him how delicious these foods are when they are ripe, for fear that he won't be able to fall asleep at night.

Natural rubber has accumulated a lot, but there are not many places for temporary industrial needs.Luo Guiting used instruments to make latex mattresses from rubber.Of course, the machine can't make such a big thing at one time. Luo Guiting made one meter square and ten centimeters thick mats at a time.

Luo Qiren was lying on two latex mats, and he couldn't believe the feeling he had never experienced before.He stuck to it almost when he lay down and refused to get up.

It's a pity that it is only one meter wide, and it is difficult for Luo Qi to turn over.

"Make two more and you'll be able to sleep well at night."

The temperature inside is constant, even without a quilt.With such an extremely comfortable mattress, I believe Luo Qi can also sleep well.

He had been woken up for more than a month, and finally he was able to sleep properly.

Thinking of this, Luo Guiting couldn't help feeling sad.

Luo Guiting was still imagining that the poor kid didn't enjoy it, but Luo Qi said rather non-greedy: "Where's the agreed rabbit fur?"

"..." It seemed that I was worrying too much.Luo Qi is not a person who can wrong himself.

"There is too little rabbit fur. What you make now is enough to cover your stomach, and the mattress is still far away."

After the shovel head and iron hoe were ready, Luo Guiting picked out a bamboo of suitable size as a handle and installed it on.

It felt good after trying it out, and I couldn’t wait to go to the copper mine closest to the ground that afternoon, and started working with a shovel and a planer.

Although it is underground, it can be dug within 50 meters.

This distance is already quite short for ore.

It's just how to dig safely and quickly. This requires the assistance of the system and Luo Qi to ensure it.

It was also on the third day that Luo Guiting swung his arms to mine the mine, and the long-awaited Little Chicken finally landed on the ground.

It was still night.

Luo Guiting returned to the escape cabin with a day's exhaustion. If the hatch wasn't low enough, he almost didn't get in.Because the arm hurts so badly, Luo Qi prepared the dinner.

Luo Qi gave him two injections of medicine to relieve muscle pain, but it still took a night to recover from this fatigue.

After reluctantly washing up, he just lay down in bed when he heard some sharp prompts from the system.

Luo Guiting thought he was being attacked, and sat up from the dormant cabin, only to hear Luo Qi's calm reminder:

"The chicken is about to be born."
