There is no summer and cold, people hardly have to work, everything is labored by iron men - robots. Traveling is also boring, the whole world will go to every corner in only a day or two. People travel around the world. The entire universe has no secrets from mankind.

The most terrifying thing is that the twelve countries that survived, for many years, survived through bloody fighting. Knowing the importance of strength, countries desperately strive to develop sophisticated weapons. With a spear, it is necessary to study a shield to resist the spear; with a missile system, it is necessary to have an anti-missile system, and then we must study new types of weapons that can break through the anti-missile system. These twelve countries are developing in such a contradictory mentality, all fantasizing that one day they will be the only countries in the world, or the bosses of these countries.

Various countries have developed neutron technology and made missile systems that can destroy the entire world with just one piece. People are afraid of being destroyed, and they are vigorously developing artificial intelligence, iron men, that is, robots, trying to replace humans with iron men.

He told Chen Lu that when they came in, they saw that the patrols were all iron men, and so were the doctors. Like humans, they have human emotions and desires, but they are usually not subject to intellectual constraints.

There is a Yin Huo country in these countries, which is the unwritten boss of these twelve countries, but he is always afraid of something called Thucydides Trap, and he is always on guard against others, and the microneutron technology is in the absolute lead, and the iron man technology is also a big step ahead. These iron men mastered the detonation technology of a large number of neutrinos, and finally caused a tragedy. There was an accident during the neutrino test, and the entire earth was destroyed, and everything was destroyed.

Chen Lu shuddered when he heard this, and asked, "What about you, how can you survive?"

Dr. Dulian said they were experimenting 50,000 light-years away, so they were spared poison. Now, these people are left in the Second Age. Back on the surface, those people had been irradiated by neutrino fission and had been lying here for years, they had lost the ability to reproduce, and their blood was running dry. Dr. Du Lian and they found Chen Lu and them in the time and space tunnel, and found that they had the same genes, so they brought them here and asked for some blood.

Chen Lu didn't understand it very well, but he knew, he didn't know that tens of thousands of years ago, there were very powerful human beings, who died, and destroyed human beings. According to this doctor, this is the second time.

Chen Lu didn't know what the blood transfusion was all about. He asked, "Won't we die if we give them our blood?" ”

Dr. Duren said, "Don't worry, no, we have eleven patients, and it will be enough to take 200 milliliters of blood out of each of you, and their blood will flow again, and our world will continue unscathed for you." ”

Chen Lu felt that what he said made some sense, but what is the difference between arresting people here without consent and those strange demons and ghosts? ”

Dr. Du Lian said, "Brother, you are right. I know that you are the ancient people of the next era, and you have traveled here to help us, and what we did was very inappropriate, and I apologize to you solemnly. ”

Chen Lu didn't want to say more at this time, finding a way to get out was the last word, and asked, "Why are they all unconscious?"

"Not a coma, they were given anesthetics, general anesthesia. When we speak, they hear and understand in their hearts. ”

"It's just hemp boiling, right?"

"What? Oh, almost. ”

"Okay, when can we go back?"

"You can go back anytime. I would like to say one more thing, brother, I am a doctor of human genomics, and I would like to say a word of advice, cherish this world, everyone live in harmony, and do not fight each other. Again, leave some unknowns for this vast celestial body, otherwise, when you break through the avenue, that is, when you are destroyed. Remember, you can't die. Humanity will self-destruct. ”

Chen Lu nodded, and suddenly asked, "Are you a real person or a dummy?"

Dr. Du Lian was stunned for a moment and said, "You're talking about iron men, robots, right? I'm not, I'm human, now we have three doctors, in addition to me two female doctors, I gave them blood transfusions first, two of them are normal people, and eleven patients, the whole world is just fourteen people." Of course, there are some strong creatures at the bottom of the sea that have survived. ”

Chen Lu said: "I have seen a lot of people, and all of them are false. ”

"Yes, if you don't look closely, you can't see it, and their skin is the same as ours. ”

"Where is this?"

"I can't see the sign anymore, and we don't care where it is, we call this yard Area A, and there's Area B over there, and Area C further west," Dr. Dulian said. After the blood transfusion, you go to Area B to eat and rest, and look for an opportunity to send you back. ”

Chen Lu said, "Okay, is there a real person in that courtyard?"

"No, there's only one Iron Man. ”

"Then he won't listen to us?"

Dr. Dulian smiled and said, "It's okay, he will never betray you, if he doesn't obey, you screw his ears over and he stops." ”

Chen Lu had to wait for a while, and Dr. Du Lian said, "They're all done, waiting for you at the door." You go first. I'll take a look at these patients who have had blood transfusions first. ”

Chen Lu walked out, and Hu Chun and everyone were already lined up. He looked at Chen Lu coming over and said, "Report to your lordship, the personnel are already ready." Chen Lu breathed a sigh of relief and searched for everyone's name, this is just a blood transfusion, not fatal, and there is no harm to the body. After speaking, everyone seemed to understand or not, and I couldn't understand it myself, so I walked to another courtyard with everyone, which is probably the B area that the doctor said.

Everyone was dressed in cotton clothes, but the sun here was like a big furnace, scorching the earth mercilessly, and when you looked around, it really became a scorched earth, and you could not see a little greenery, nor a living thing. The whole land has lost the slightest bit of life.

Chen Lu thought of the doctor's words, and his heart swelled with sadness.

When everyone walked to the gate of this courtyard, the gate opened automatically. A voice came from Chen Lu's ears: "Welcome, please come to the front hall for coffee." ”

Everyone followed Chen Lu and walked to the front. When everyone went in, they saw a neat dining table, which was completely different from their own, and the furnishings in the room had never been seen before, and everyone forgot the unhappiness just now, and looked around.

The voice sounded in my ears again: "Everyone, please take a seat, there are so many people, I have to prepare, and I will come in a few minutes." ”

After a while, a giant cart came up and said, "Please serve coffee." ”

Chen Lu said: "One cup per person, serve it yourself." After everyone put it down, they looked at Chen Lu. The giant cart walked around, then turned around again, and said, "Put the sugar in the tray, please use it slowly, and serve you synthetic bread and steak later, please." ”
