Lu Yuan and Su Mei knew nothing about what happened outside the world, so naturally they didn't know the conversation between Zhao Junli and Lu Yao.

Humans are concerned about things inside their boxes, but they are often indifferent to things outside the boxes, which is also human nature.

When Lu Yuan and others came to Roland's room again, Roland had been waiting there for a long time. Although the injuries on his arm had not healed, after using medicine and supplementing nutrition and leaving the humid and hot environment underground, his body recovered quickly. At this time, he could sit on the bed and watch the three of them enter.

"What's the result?" Roland said first.

Lu Yuan looked at Su Mei, and Su Mei informed Roland in detail about the bits and pieces of this experiment, including the strange viewing range that even the camera was viewed.

And in the end, the entrance of the cave was still tenaciously present in this world, but because of the collapse of two bombardments, it was much shorter than before.

"Sure enough," Roland sighed and said.

"Don't you want to hear the story?"

"Then I will vaguely remember it now, so I will tell you my story."

"My story is actually very simple to say."

"In a word, I was only seven years old when the sun went out."

Su Mei instantly calculated Roland's age. So far, the sun has been extinguished for more than 35 years, so Roland is only forty-two years old now?

But even though Roland has cleaned up now, he looks like he is fifty years old. It is not surprising that you are sixty years old.

Probably because I was tired in the second half of my life, so I was over-aging.

After all, in the end of the world, it is impossible to be as pampered as the civilized society before the end of the world, and to live a life of luxury everywhere and not seeking anything from others.

"Then?" Lu Yuan continued, "You probably have lived in this cave since the end of the world, right?"

"And as far as I know, this cave should not have been discovered before the end of the world."

"Yes." Roland nodded slightly, and looked at the gray-haired middle-aged man in front of him: "I originally lived in a nearby shelter, so I don't need to investigate. As far as I know, that shelter was destroyed ten years ago."

"And I came here eighteen years ago." Roland continued.

"Did you find this cave?" Lu Yuan guessed.

Roland nodded: "Yes, because at that time, the resources of the shelter were gradually short of, and talents from all walks of life continued to wither and die, the suicide rate remained high, and the fertility was insufficient, even if there were children who had children."

While saying this, Roland glanced at Su Mei: "Most of them cannot implement sufficient education. After all, adults are too busy to take care of themselves. Who is still in the mood to teach children something?"

"After all, human beings are about to be destroyed. I said that children are the future of human beings."

"Now that I know there is no future, why should I educate those children?"

"Anyway, after nearly twenty years of surviving in the ice and snow apocalypse, my refuge has reached the brink of collapse."

"At this moment, the parade outside suddenly heard news that a bottomless cave appeared here. After going deep into it for a hundred meters, you can feel the temperature rise significantly and you can see the existence of liquid water." Roland looked at Lu Yuan.

"What would you do if you were the commander of the shelter?"

Lu Yuan looked at him without any hesitation: "That must be sent to investigate immediately."

If you have a complete underground shelter with geothermal heat, it will definitely be twice the result with half the effort. Most humans in disasters no longer have enough manpower and material resources to ask for a deep enough distance from the ground to obtain geothermal heat and warmth. Of course, most people who are still living in this world now have already survived underground, and the shelter built on the original buildings will soon fall into food scarcity and energy shortage, and thus slowly decay.

Of course, the main reason for death in Bay Area shelters is not the exhaustion of nuclear fuel, but the story of all the water that can be used to cool frozen into ice.

In short, because we have not experienced the real test of extinguishing the sun, most refuges designed by humans in a hurry will ultimately be unable to escape the fate of failure.

After all, there are some things that there are no mock exams in this world.

However, the mechanical pioneer shelter, which is closest to the correct answer, embarked on the path of completely denying humans and becoming enemies of humans.

It must be said that it is a great irony.

"Yes, we did this too." Roland looked at Lu Yuan with a sarcastic expression: "And I am a member of the first investigation team."

"At that time, the world was still snowing, and it was endless nitrogen snow for decades. We all felt the cooling of the earth, just like feeling a dying corpse becoming cold little by little."

"And it is ironic that we are the germs on this dying corpse that are trying to resist."

"That was how I felt at that time."

"Then we entered the inside of the cave. At first, everything felt good. The entrance to the cave was incredibly spacious. Such a huge cave had not been discovered by humans in the past countless years, which made us amazed each other."

"You know, although I have a very effective memory of the era of human civilization, I have read a lot of books and video materials. I know that in the period when humans are victorious, we not only set foot in the Antarctic and the ocean, but also on the moon and Mars."

"It is impossible to say that such a cave was not discovered by humans, but there has never been a record of this strange cave in the records of the environment around our shelter."

"We suspected at the time that this cave might have been exposed to the ground due to changes in the crust in the twenty years after the sun was extinguished, but our geographical knowledge was very ordinary, and it was impossible to send useless geologists to study these."

When he said this, Roland looked at Lu Yuan and others and smiled sarcastically: "I heard that when humans were prosperous, any scientist with a marginal sect could find their right place to survive."

"And at this moment, if a scientist cannot prove his value, he must work in a coolie to prove his most basic value."

“For example, a scientist who can prove the reason why the sun is extinguished is far from an engineering scientist who can make our coal generate electricity at a higher yield.”

"Even if the former is actually thousands of times more precious than the latter."

"Anyway, we got out of the way, we entered the inside of the cave and found many interesting and strange things."

"Then, at the deepest point." Roland took a deep breath and said with a horror expression:
Chapter completed!
