Kotel Building, 2000 meters underground

"Now that Ling Wei has woken up, I'm going to find my master too" Tota contacted LAN and decided to go to the bottom of the pyramid.

"Brother, are you willing to leave us?"

"Reluctant? What is that? I'll look it up. ”

"You're just pretending, aren't you? I read the map every day, and the book of days was also loaded for me. Alright, brother, I won't keep you, after all, you have a spirit companion, but you are lost. ”

WN confessed to keep Ling Wei's soul for three months, and tota my mission has been completed. Tota flew to WN's side, grabbed the awakened WEN's hand and said, "Brother, see you back to your home planet." ”

"The LAN is already at the beginning of the return to the star, and you can enter it through the entrance of the Hop Tower."

Du Heng, Ling Wei, and the Impaleing Beast, after sending Tota away, got along together for a while, and during this time, Ling Wei would be a super doctor to see a doctor for WN, and a medicinal dietitian for him, making medicinal meals for him to restore his body's spiritual energy.

Every day, there will be nanny robots coming to visit WN, and they say that they are still very willing to follow WN and Duheng to overturn today's explosive government, and they are not willing to go back to the old days. WN said that he would continue to recover them as long as his body recovered. The Impaler, however, took over the task by repairing the protective shield shattered by Dan, and then repairing the bodies of the nanny robots inside.

After all, Du Heng and Ling Wei are psionic creatures and earth humans, and it is not suitable for them to live underground for a long time. But I have been worried about the situation of WN in my heart, and on this day, Du Heng and Ling Wei explained that the Piercing Beast π take care of WN at home, and they need to go out to purchase some materials needed by humans.

"Doctor Ling?"

"Although I'm a medicinal dietitian, I'm not a doctor, don't scream" Ling Wei felt very strange, recently this Du Heng always asked himself, is it a short circuit in the brain?

"Weiwei, go"

"Go there?"

"Shopping!"

Du Heng pulled Ling Wei over, put his long hand on her shoulder, hugged Ling Wei and left

"Hey, hey," Ling Wei dodged, jumped forward, and said seriously: "Don't bully me for amnesia, did we know each other so well before?" ”

Seeing the serious Ling Wei, Du Heng couldn't tell if the doctor was back or the medicinal dietitian. I had to say: "Very familiar, we have all been married before, don't you remember?" ”

"I believe in you! Size! Let's go, where to go? ”

Du Heng activated his spiritual power and led Ling Wei to jump outside, and the super yang strong sun instantly stung the eyes of the two of them, and they put their hands on the pergola, but they couldn't block the strong light reflected from the ground. The surrounding bare roads, the lifeless earth, the streets without a single tree, everything you see is simply indescribable, people are all expressions, walking on the street without expression, the robots of this era have almost the same appearance as humans, and they are completely indistinguishable. The people walking on the street were exposed to the direct sunlight in this way, and they did not feel as uncomfortable as the two of them.

The super yang strong sun instantly stung the eyes of the two, and they put their hands on the pergola, unable to block the strong light reflected from the ground. Robots in this era have almost the same appearance as humans, and they are completely indistinguishable. The surrounding bare roads, the lifeless earth, the streets without a single tree, everything they saw was indescribable, people were walking on the street with blank expressions, and the people walking on the street were so directly exposed to the sun's rays, and they didn't feel as uncomfortable as the two of them.

Du Heng pumped from his shoulder, wanting to see what he could pull out, but then he saw that it was an umbrella? No, it's an umbrella-like electronic light energy device, I see, like a rolling pin-like stick, both ends are empty, all black, like a pump, Du Heng pressed the red button on the umbrella handle, only to see this rolling pin-like cylinder, one end on the top of their heads like a jellyfish like a ripple slowly unfolded, and there are countless silk threads hanging around it, the only difference between this guy and the umbrella is that the umbrella crown that looks transparent can effectively block the sun's light, and it doesn't need to be held by hand, it seems to be inductiveWherever the person goes, it follows. Ling Wei looked curiously at the super beautiful guy in Du Heng's hand, and was stunned.

"Yikes! Duheng, where did you get it? So beautiful. ”

"This, my dad sent it" Du Heng really didn't know how to answer, embarrassed.

Ling Wei, who was still immersed in the unspeakable dreams of beautiful things, asked while stunting the beard hanging from the umbrella crown with his hand, "Du Shangyun?" ”

"Do you remember?"

"When you were in Frozen City, you told me his story, and you said that you didn't think you would be Du Shangyun. At that time, I thought, maybe you are the little boy in the story. ”

"Yes, I am indeed my father"

"Have you seen him? No wonder I don't think you're the same as when you met Frozen City."

"What's the difference?"

"Humans who can fly to the sky and bring alien creatures, you say there is a difference?"

Ling Wei's description is indeed that Du Heng has recently been running around his room and the gathering place of many nanny robots in order to take care of WN, because it is too late to walk at the speed of earthlings.

On the road, there is not a single tree, only high-rise buildings, and the façade is also a solar silicon panel collector, in fact, since then, the only energy resources that can be reasonably used on the earth are solar energy, and all the society that uses electricity has a great demand for solar energy to convert into electricity.

The solar silicon panel collector was also converted to the later levitating magnetic solar collector due to the gradual depletion of silicon ore, but the magnetic ore is also slowly depleted, and the energy circuit of the solar AI robot is also on the agenda.

Du Heng and Ling Wei finally saw a middle-aged man with curly hair and dark skin, and Ling Wei walked up and greeted the other party: "Hello! What kind of road is this? ”

The other looked at her with monster-like eyes, and said to their jellyfish umbrella, "What is the road?" It's still on the mark."

"Oooh. Thank you! ”

"Thanks? What is it? Do you have seeds? ”

"Seeds?"

"Or freshwater?"

“what?”

"None of them, did they? Then give me this one on your head. ”

"This, this is my hairpin, what do you want it to do?"

"Because I answered your question, you should give me something as a thank you"

"Oh, oh, oh, okay, here you go" Ling Wei took off the hair card without hesitation and gave it to the black man. I saw him take the hairpin and look at it for a long time, and left happily and hurriedly.

"It seems that the world is indeed different." Looking at the whole process of the black man and Ling Wei just now, Du Heng seemed to have guessed something. "You still have three hairpins on your head, and it looks like you can find someone to answer three questions"

"It's strange, you have to pay for asking for directions."

"It's not about money, haven't you noticed? He only needs supplies. ”

Seeing a young man with an Asian face walking in front of him, Du Heng walked up to greet him

"Hey, I have a hairpin here for you either?" Duheng removes the hair card from the Lingwei head

"Really? What do you need me to do? Looking at the hairpin in Du Heng's hand, this person was very friendly.

"Well, we want to know, don't you use money now?"

"Money? Do you mean that? The young man took a small device out of his pocket, tapped it, and a string of numbers appeared on the monitor on it, "We all call this money"

"Oh, oh, e-money"

"So, are you going to work?"

"Are you a robot?" The young man looked at Du Heng very suspiciously.

"Me? No, why do you ask?"

"Don't you know that most of the work of humans is now replaced by robots? Since you are human, what is your job, I ask? ”

"Me? I am a Chinese medicine practitioner and acupuncturist. Treating human beings"

"Oh yes, doctors do still have jobs. After all, it takes a doctor to replace the facilities on the body, but if this continues, I think that the doctor who can only treat humans will also lose his job."

"Why?"

"Because there are fewer and fewer human beings, they can no longer reproduce children, they are all cultivated with the help of robots, if it is not for the government to use the law to compel them, many people don't want children. Many of my friends only bask in the sun every day at home, eat and drink with nothing to do, and all the robots work for them, and the stars they see every day on TV and radio are robots, and humans are too lazy to do anything.

The AI robot produced by Kotel has an energy harvester at the head, which can directly collect solar energy in the sunlight and convert it into the electricity it needs. Not only the direct sunlight, but also the moonlight, which reflects the sun's rays at night, can still be collected.

In this world, only Kotel's robot can collect the sun's energy directly through a receiver on its head, and then convert it into electricity to charge its own body.

This technology of direct solar energy harvesting is a global patent of Kotel, and of course many competitors want Kotel to open up this technology and make it open source for them to use. Give them the power to produce their robots, because the earth's resources are indeed close to being exhausted, and the number of silicon panels that can be converted into solar energy is limited

The energy efficiency of energy harvesting made of silicon panels in 2320 has been greatly improved, but the silicon panels on the earth are also close to exhaustion, and all electrical equipment that relies on the earth's existing minerals or ores or mines to provide energy and energy efficiency is about to face a total depletion of energy.

"Today, when Mo Dai has the ability, he will collect and keep these gems one by one, and that day Mo Dai has no ability, and they don't know what their fate will be, after all, dust will return to dust."

Otel Mo Dai is still trying her best to lure Gou Cong Rifang to accept the bribe specially arranged by her, although Gou Cong Rifang already wants to give this luxury gift like a cat's claw in his heart, but he is still holding on to it on the surface.
