Humans became extinct after returning to Earth [Infrastructure]

After searching hard for more than two months, the two finally received the first message transmitted from the earth.

"Don't send any more signals!"

Is this a warning?Not quite.

More like a reminder.

Is this related to the undetectable signal on the earth?

It's not that they disappeared without a trace, but that the surviving people dare not let outsiders know of their existence for some reason!

Thinking about it further, Luo Guiting's cold sweat has already come down.

"You turn off the signal transmission first, as long as you accept it, let's go back and study it slowly!" Luo Guiting said.

Luo Qi shook his head: "It can only be closed together, and the reception can also be detected."

Luo Guiting turned his head and pulled the fishing net back, he had lost his mind to see what he had caught today.Instead, let the bamboo raft land quickly.

After landing, take away the things you want to take away first, put the bamboo raft away, and then rush back to the building without stopping.

The boiler room was already lit, and he went upstairs to enter the laboratory. The warm room was isolated from the cold. Luo Guiting took off his cold coat first, poured himself a cup of hot water, and felt refreshed.

Not only was it cold outside, but also after receiving this unclear news, he was panicking from the cold in his heart.

"Will that person be a survivor?" Luo Guiting asked.

Luo Qi looked at this matter a little pessimistically: "Not necessarily."

"Artificial intelligence?" Luo Guiting was not stupid.

If signal transmissions are dangerous, well-meaning people who warn them will not be so stupid.Most of them are reminders from machines.And how long ago this machine was left, they have no way of verifying it now.

It was this uncertainty that made Luo Guiting very anxious.

"It's a pity that we can't do reverse tracking now."

Luo Qi was silent for a while, and the two looked at each other.

Luo Guiting first expressed his opinion: "If there is any danger of tracking the signal, we really need to be cautious. But we have been back for more than two months, and the signal has not been released for a day or two. Until now There is still no so-called danger found, maybe the risk factor is not so high anymore."

This message, which may have come from hundreds of years ago, may not apply now.

"You can't take any risks," Luo Qi said.

"If there is danger, our safety is unexplainable until now."

"Actually, I have an idea." Luo Qi said.

"Say it."

"I know the approximate location of the source of the signal. We can make a signal transmitter, let it drive there from the water and keep emitting signals."

"But if we take over his signal, we will also be tracked." Luo Guiting knew that Luo Qi would be thoughtful, but this kind of question still needs to be asked clearly.

"So don't send us a receipt, and completely cut off contact. But the moment it is destroyed, the last message will be transmitted back. It's just a moment, and the other party can find out the approximate direction at most, but they can't track it here."

This is indeed a feasible method.

Luo Guiting went through the plan in his mind: "What materials are needed then?"

It is definitely not enough to rely solely on the existing gadgets. It may be necessary to use the things found in that shelter.But some parts and mods are still available.

Luo Qi immediately began to draw the design drawings.

The scallops are left to the manipulator to be busy.

The surprise brought by receiving the signal this time made Luo Qi temporarily forget the temptation of delicious food, and concentrate on analyzing what changes this contact might bring to them.

In just three days, the signal detector was successfully launched into the water.It is equipped with AI signals, and it will learn to solve problems that may be encountered along the road by itself according to the situation.

And when it fell into the water, the two fell into conflict.On the one hand, I was worried that there would be no news from it, and on the other hand, I was worried that it really sent back a message, which meant that it was really destroyed.

Either way, it seems like they shouldn't be putting all their eggs in one basket.

The sun hid behind the cloud for half a month before he was willing to come out.

When the obviously not so warm sunshine hits the body, it can actually bring people some hope.

Luo Guiting went to the edge of the cliff on Zhuzi Island, recreated the mechanism for climbing up and down, went down the cliff and went straight to the shelter where he thought he would never return.

Most of the valuable things inside have been emptied, but the buildings inside are quite pleasant in terms of safety and concealment.

There is no other reason for coming here this time. After a little repair, I left a batch of emergency supplies here just in case.

If the deepest event of force majeure happens, with this place as the last safe haven, at least there is still a glimmer of life left.

It's just that when I think of a person who was trapped here alive and came here again, I feel somewhat depressed.

"It seems that this gate needs to be repaired." Luo Guiting looked at the alloy gate weighing hundreds of kilograms and fell into deep thought.

In fact, these two doors are already considered light.If it was Luo Guiting's time, building a door with this kind of defense and specifications would have weighed at least three to four times.

Lifting it up and repairing it is still a problem.

"It can be used as a tool to help you up." Luo Qi was not in a hurry when he arrived.

Just as Luo Guiting was about to speak, a pop-up window appeared in his glasses. After clicking OK, everything in the room changed.

Here is the AI ​​planning map made by Luo Qi. Walk through each room, and each place is arranged differently according to the terrain.

"In addition to the nutrients that can be stored for a long time, you can also put some smoked dried fish in the food. As long as it is vacuum-packed, it will be fine to eat for a few years."

Luo Qi only said: "You can put it here."

"Just prepare two more packs. I also put some of the wine found in those small buildings here."

Still the egg basket rule.Divide the supplies into four, put the most on the building and Luo Qi, and then divide a little bit into the escape cabin and the shelter here.

As long as you are not fatally wounded.Then Luo Guiting could survive.

With their current conditions, Luo Guiting couldn't live without this small island, so that was all they could do.

Luo Qi didn't object any more, and after discussing some details, the two of them put away the things they brought, and then came over every other day to sort them out.

While busy with this, Luo Guiting did not forget the previous plan.

When the temperature drops a bit, all the crops that can be moved indoors are transplanted. There are not many seeds on the left and right, and few are sown indoors.Still waiting to get seeds for the original crop.

After feeling the cold outside, Luo Guiting took a laser gun and plunged into the forest, encircling and suppressing rabbits weighing more than ten catties.

After they hunted down a large number of black ants, the threat to the survival of the rabbits was greatly disintegrated. In less than three months, the number had nearly tripled. It should not be too much to kill a few rabbits for such a great contribution.

Luo Guiting didn't ask for more. After saving enough a vest and a rabbit fur quilt that barely covered him, he stopped and killed more than a dozen rabbits.

Luo Guiting's clothes and clothes were settled, and Luo Qi's belly was also bulging.

If you can't eat it, marinate it and put it in the drying room.Fumigate some herbal medicine inside to add a bit of flavor to the meat and greatly extend the shelf life.

Luo Qi and his own rabbits have been raising for more than three months. After winter, these rabbits can be killed at any time if they want to eat fresh. It is a very fresh food.

Chicken is treated similarly.

The temperature is still dropping, and as the temperature drops, the leaves of vegetables that are not suitable for transplanting begin to wither and fall off as the temperature drops.

Especially cucumbers and tomatoes.I picked all the immature or immature fruits in one go, and the rest had to be uprooted and fed to chickens and rabbits.

Peppers and eggplants were moved indoors, a few died, but most were still alive.The reproductive period of these two is far from over, so let's keep it for now.

Three and a half months after Luo Guiting returned to Earth, the corn had just matured. In fact, not many were planted. Even waxy corn and ordinary corn, there were only forty in total.I have harvested more than 50 corn cobs. It is actually quite difficult to count this as a staple food.

After the soybeans were leaned into the room, Luo Guiting stopped eating them for Luo Qi, and kept all these as seeds, and planted some more after harvesting the seeds.Try to make Luo Qi realize Maodou's freedom within half a year.

If the sweet potatoes were not harvested, they would freeze to death, but they had no choice but to dig out all of them in one go. Maybe they were harvested earlier and they were not very big.

After the yard was completely clean and even the shelves were removed, Luo Guiting finally didn't have to worry about going to the field in the wind and rain to check at any time, but the job of going upstairs every day still couldn't escape.

At the same time, there is no ambiguity in the hoarding of fuel.Needless to say about coal, Luo Qina has to take a bath twice a day for nearly a month, even if she wipes her ears, she may get dark marks.tidy

And Luo Guiting chopped back the bamboo, directly chopped it into a size suitable for burning fire, sent it to the drying room, and directly baked it into dry firewood for storage.

The firewood is stored in the corridors and under the stairs, almost filling the places outside the house almost every time.

There are robots monitoring and patrolling, but we are not afraid of any potential safety hazards

Just when the temperature is close to zero on cloudy days and only within ten degrees on sunny days.Luo Guiting, who was basically fully prepared, planned to welcome the first winter after returning to Earth behind closed doors.

Unexpectedly, Luo Qi received the signal.

One good news and one bad news.

The good news is this is not from the machine they sent out.

The bad news is that there are only two words on it.

"Help."

Luo Guiting broke out in a cold sweat the moment he saw it.

"Are we going to expose it?" Luo Guiting asked.

Luo Qi shook his head: "I don't know, but this signal source is very close to us."

Luo Guiting's voice raised a bit: "That's even more dangerous!"

"But it is very likely that the person calling for help is a living person."

"Then what if it's the enemy's bait?"

"At least you know if you know it."

Feeling Luo Qi's insistence, Luo Guiting no longer objected.

"At least send the detection machine over there first, and don't go there first. Even if there is danger, we at least have a chance to hide."

That refuge was only discovered by them by accident in 500 years, and it has been almost repaired now. When the shielding mode is turned on, it will not be easy to find.

Luo Qi immediately modified the robot that had been used to catch fish.Its own functions are relatively complete, and this modification is actually just to increase its battery life and power.

Three hours later, the two arrived at the beach. Luo Guiting pushed the robot into the water while dripping in the cold sea water, watching the robot stretch out all the way to the sea.

Luo Guiting clenched his fists tightly, no one could tell what kind of change this change would bring to them.

But Luo Guiting believes that since he can live to be 3000 years after the earth, then fate will not treat him too badly.

Even if you treat him poorly, he will do his best to turn over.
