Humans became extinct after returning to Earth [Infrastructure]

Suddenly hearing the siren in the middle of the night was not an accident, nor was it an animal birth.

It turned out to have received a distress signal!

Everyone in Luo Guiting stood up and hurriedly asked about the situation: "Where is the signal? Is it far from here?"

Luo Qi manipulated it with his mind, and said: "It came from the mainland."

Luo Guiting frowned upon hearing this: "On the mainland...is it true?"

I'm afraid it's not the smoke bomb of that extremist organization.

If it was a smoke bomb, would the signal received here have been discovered?

Shouldn't they be moved to an underground shelter as soon as possible?

Luo Qi didn't return, but got up to pick up the messy clothes thrown away last night.Luo Guiting hurriedly helped put it on, and just in time to meet Wen Cheng who was going downstairs on the way up the stairs.

"Are you sure?" Luo Qi asked.

Wen Cheng nodded: "It's almost there, the distance is too far, we can't make it through."

Luo Guiting asked, "Could it be a smoke bomb?"

Wen Cheng shook his head: "It's unlikely, even if there is a real risk, I'm not afraid to expose us."

Luo Qi said: "But the signal is very strange."

"It's really strange. It's just asking for help, without specific circumstances. I don't know the environment and situation of the other party. Rescue is just empty talk. But we can't reply to the inquiry yet."

The three of them went to the laboratory first, and it was a bit cold upstairs in the laboratory at night.First moved the charcoal basin to increase the temperature.Three people surrounded the charcoal basin.

Luo Guiting looked at the map of the current mainland. The area where the signal was sent was far away from them. After arriving on the mainland, he had to walk out of the distance that was more than three times the distance from the mainland.The waterway is easy, they can get by, but the land is difficult.First, there is a lack of transportation, and according to what Wen Cheng said, there are eyes of that extremist organization everywhere.

How easy is it to want the past?

So they have no way to save them, even if they have the conditions, they have to carefully consider whether to go.

"I don't recommend going," Wen Cheng said. "It was too risky in the past. If he can escape here by himself, we will naturally rescue him with all our strength. But if we don't have the ability to take out, then it will be difficult for us to rescue him." .”

It wasn't that Wen Cheng didn't care about the lives of others after he was rescued, but that this matter needed careful consideration.

Luo Qi didn't speak, rubbed his hands while warming the fire, and looked at Luo Guiting.

After calming down for a while, Luo Guiting had already thought a lot about it.

"Look at this route, from here, to here, and here, there is a small amount of greenery."

Wen Cheng twitched the corners of his lips: "Are you really planning to go out?"

"It's inevitable. It's still the same sentence. We can only wait for death here. Even if they don't come over, we will go crazy sooner or later in the fear of being found out. It's better to go out. If we can be rescued More people, and even have the opportunity to contact compatriots who may exist in outer space, we have the probability of completely turning over."

Luo Guiting is very serious about this and has always insisted on it.He's not one to sit still.Of course not a brainless charge.

He is from the Air Force, and he understands the best way when the enemy is strong and we are weak.

Detours, development, growth, surprise victory.

The sparrow battle is always nothing but the biggest problem they face is to hide themselves in extreme environments.

Now is no longer the time to just hide behind a tree and the enemy can't see you.If you exist in the detection of the other party, the other party will definitely sense the reflection of life, and then find someone.

If there is a device that emits signals on the body, it will be discovered faster.At that time in Luo Guiting, there were almost no cases where the enemy sneaked in secretly. Now, it is even less of a problem.

Looking at the location pointed out on the map, Luo Qi suddenly thought of something.

"Biological confusion..."

The two turned their eyes, and Luo Qi said, "Animals migrate for food. It's nothing more than normal."

Luo Guiting was confused when he heard it, but Wen Cheng, who was at the same age, saw his eyes light up: "You mean to change the biological signals so that they think we are animals migrating, and then cheat the world."

"It's totally doable, as long as it doesn't get photographed."

The two first reached a consensus and felt that it was completely feasible, and then explained to Luo Guiting.

"There is a technology in the 45th century, which is to allow an animal to be detected as another animal after being sensed. More advanced, even the optic nerve can be affected, allowing an animal to see another animal, giving him a signal to wear a book, It's what it sees."

What kind of nonsensical function is this?

As if seeing his question, Luo Qi explained: "The former is done by environmentalists. The latter is done by animal watchers."

Wen Cheng added: "In some places where species invasion is involved, a specific species will be wiped out. However, some environmental protection awareness thinks that species invasion is also part of biological evolution, and will protect those animals that are so large that they affect the ecological balance. So develop shielding tools to protect them."

"After 500 years, there are still such extreme environmentalists?" Luo Guiting only thought it was funny.

If invasive animals are protected, who will protect the animals that are extinct due to animal invasion?Of course, the 45th century has a perfect gene pool, and whatever becomes extinct can be bred immediately.But the natural environment should be kept at a stable and controllable level.

Wen Cheng looked at Luo Guiting for two seconds.

"Who do you think those people are hunting down and killing humans around the world?"

Yes, extreme environmentalists are everywhere in the mainland, or the robots of environmentalists are everywhere.

Luo Guiting tapped his forehead.

"Then let it work, just use this. We can't dawdle anymore, we must make a plan. If we want to go to the mainland, we may still need a submarine. Wencheng, is there any possibility of repairing your submarine?"

"You can but don't have to. There's that consumable making a sturdier one."

"It means that there is no such raw material." Luo Guiting looked at Luo Qi.

Luo Qi said: "I have detected submarine chips in the sea."

"That's also fragments." I'm afraid it's even harder than Xiu Wencheng's submarine.

Luo Qi shook his head: "It fell off from the main body, and the main body will not be too far away."

"If it has sunk for 500 years, it is normal for a piece of debris to be carried away by ocean currents."

Luo Guiting only refuted Luo Qi, but he really couldn't figure it out.

"There is no 500 years, at most 50 years."

50 years is also a long time.

Seeing Luo Guiting frowned, Wen Cheng couldn't help rolling his eyes: "Are you still afraid that we don't know what to do?"

Luo Guiting no longer insisted on this matter.After all, he is not a professional.

"How sure is that?" Luo Guiting only wanted to hear this.

"Six...six to seven percent." Wen Cheng looked at Luo Qi for confirmation.

Luo Qi didn't respond, but changed the subject: "If we leave, what will we take with us?"

Although it has been said that he will leave in the coming year, the current development is actually more suitable for staying on the island for a long time.

Although after people leave, the remaining robots can run automatically.Those who can leave will not be able to enjoy it.

It also involves the question of what to take away.

Luo Guiting manipulated the glasses and retrieved animal and plant models from them.They set up the sharing knowing others can see it.

"It is definitely unrealistic to take away pigs, cattle and sheep. Even if there is enough space, cleaning is also a problem. The best choices are chickens, ducks and rabbits. The cleaning pressure of rabbits is also great, but the advantage is that they reproduce quickly. We have several now. The doe is pregnant."

Luo Qi hesitated a little: "You can take two pigs."

He had been thinking about pork for so long.

"Then take two! If you really want to eat before leaving, you can kill one or two cows and sheep and take them away to eat slowly. If you encounter other gene pools on the way, we should cultivate more."

If you can't come back, you won't be able to eat the meat here.

"Then dogs and parrots also need to be brought along." Pets are also needed to relieve boredom on the road. "For vegetables, we don't need to make a vegetable garden in the submarine. Just keep some good ones that can be grown without soil. You can keep a few Pots of peppers should be sprayed on, and picked at any time when eating. We don’t have to stick to fresh ones, after all, we have all gone out, and eating too delicate will take time.”

Luo Qi frowned and didn't speak, Luo Guiting said again: "Of course, as long as convenience is the premise, we should try our best to be satisfied if we can eat well."

Luo Qi said: "Vegetables can be kept fresh for several months."

Luo Guiting thought it was a question sentence, and immediately there was a list of vegetables with the highest storage in front of him.

Among them, vegetables are divided into four levels: "fresh", "second-fresh", "best for a long time" and "not fresh". Taking spinach as an example, the fresh period is about one month, the second-fresh period for three months, and the best for half a year. It has a long-term shelf life and is classified as stale after eight months.

If it is dried spinach, Luo Guiting still thinks it is understandable.But this list is obviously fresh.

Sure enough, it is the preservation technology of the 45th century.

"This is an ideal state, but it needs to be dealt with." Luo Qi said.

"You can leave it to me to make this machine," Wen Cheng said.

"Then build the machine first, and then calculate the time, so that those vegetables can basically be picked up and taken away before we leave. As for the later planting, it is the program for the robot to input. Regardless of whether the submarine can be used or not, we must Wait for the sea to melt. How we can transport that is a problem."

This time will take four or five months at least, and half a year more.There is no rush.

They will go out sooner or later, so they have to make all the preparations before going out.

As it was getting dark outside, Luo Qi glanced at the time.I couldn't help but yawned.

Luo Guiting directly picked him up and went downstairs to sleep first.

Since then, the three have performed their duties.

Luo Guiting is mainly in charge of animals and plants, and he is fully responsible for the arrangement of vegetables and livestock.Wencheng wants to make a machine that can store food for a long time.They didn't need it before, they could eat fresh ones anytime, and it was convenient to feed the leftovers to dogs, pigs, cattle and sheep.

But right now it is urgently needed.

Luo Qi mainly makes robots.For the 45th century, this is actually not very difficult, as long as there are materials.If you encounter a more complicated part, ask Wen Chengcheng again.

This shows that there is an advantage of a technical nerd in the team.
