When the old man raised his head and took the information in his hand, Hai Ge saw his emaciated, wrinkled face and silver-rimmed glasses on the bridge of his nose, and he was even more sure that his guess was correct.

Success denied his speculation and corrected: "Of course not. Albert Einstein died a century and a half ago, how could he have survived to help humanity cope with the solar catastrophe? That is a researcher at the China Institute of Space Physics, Professor Li Zhengsong. The heat-resistant and cold-insulating materials used to build the ice castle, the nano-scale polyurethane metal foaming solution, and the non-chemical ice bricks containing the solution, are his masterpieces. In the past, earthlings used phenolic foam to keep cold out, and that thing could only be used in sewers. Professor Li uses nanotechnology to foam hard metals, such as titanium, into countless tiny foam filaments, which are then burned with fire to obtain a milky white foamed metal solution. The molecular density of the solution is hundreds of thousands of times looser than that of the unprocessed metal plate, which can well lock the cold or hot gas in the molecular gap, but the liquid still has complete metal properties after condensation, and can be used permanently after injecting the ice brick, so it has become a lifesaver for the earthlings at this stage. ”

"The idea of the ice castle came from that Professor Li Zhengsong? No wonder he ......" Hai Ge realized the reason why the old man wanted to commit suicide at this time, and while admiring his sense of justice, he also thought that he should not be like this.

Although the Ice Castle was able to temporarily save humans from the strong heat caused by the sun, and they could live normally when they migrated to the Arctic continent, they were occupied by the wealthy class after they came out, and became a luxury exclusively for them. But that's not the most distressing. In order to fight for the ice castle, humanity ignited World War III when the earth was already in danger and was about to be destroyed, resulting in the loss of countless lives in the war. The ice castle was the fuse of the great war, and the old man thought that he was to blame and needed to be responsible for the death of the earthlings, so he couldn't think about it......

Looking at Professor Li Zhengsong, who was old but still working tirelessly, Hai Ge not only did not regard him as the culprit who caused the war, but also respected him. Scientists have worked hard to create an outcome that has nothing to do with war. As for the way in which the various strata of society later used his results, he had no right to interfere, and even if he did not want to, he had no right to speak, let alone take back the invention and make people forget its existence. This is the sorrow of scholars, but also the sorrow of the earth society.

"If Professor Li Zhengsong really ended his life with guilt because of the war caused by the ice castle, what a heavy loss it would be to the earth!" Haige sighed.

"But no," Chenggong agreed, "if it weren't for Mr. Wedel's timely intervention to save him, it's hard to say whether there would have been the birth of the Redeeming Light Organization." It was through him that Mr. Wedel was able to get in touch with other scholars in the Global Consortium for Science and Technology. Professor Li Zhengsong is an out-and-out hero of the earth, and his selflessness and high-spiritedness are the most commendable spiritual wealth possessed by the people of the earth! ”

"Oh?" Haige sighed strangely. He was proud to have succeeded in saying this about the geographer, but another question came to mind.

"What other questions do you have?" Success asked.

Hai Ge said: "Listening to what you just said, how can I have a feeling that in fact, the earth science community has long been aware that the sun is changing, and a catastrophe is about to befall the planet where they live? But what did the scientific community do? If there is no Redemptive Light Organization, those experts in physics, astronomy, aviation, chemistry, etc., will sit idly by and ignore the fact that the sun has entered the red giant phase ahead of schedule and is about to have a helium flash? Hai Ge looked away from the Chinese "Einstein", that is, Professor Li Zhengsong, and asked gloomily.

He replied: "Indeed, as you said, as early as 60 years ago, unusual changes in the sun were discovered at the observation points of the earth's major astronomical observatories. Although people can't believe that the lifespan of the energetic protector of the solar system has been cut in half due to the threat of the black hole of the U star directly below, this prediction, which has been inferred to be conclusive and will definitely happen, has caused an uproar in the scientific and political circles. Some academics and politicians who are not only smart, but also always able to keep their heads clear-headed, finally accepted this fact and began to study how to make the Earth-like planet escape from the catastrophe. ”

"More than sixty years later, before Weedel came along, did they think of anything that would work to handle the case?" This is Haige's main concern.

Success replied succinctly: "No." ”

"Hey~" Hai Ge sighed, like a deflated ball. He asked, "Why?" Is it because the scientific and technological level of human beings on the earth is not high enough, so they can't save themselves? ”

Chenggong replied: "The development of science and technology is limited, and it is only one aspect. I think they also have some misunderstandings in deciding on the direction of research.

"What do you mean by that?"

"Most scholars on the planet only focus on the existing scientific fields and do not try to broaden their horizons, so they don't know that there are actually many different ways to overcome a seemingly insurmountable difficulty. For example, when they often mention Noah's Ark, their thinking is limited to loading the most precious or useful civilization heritage or resources on the planet and escaping from the solar system or even the Milky Way, without thinking of treating the entire planet as an ark and dragging it to the safety of space. ”

"This ......"

Haige is stopped. He was tempted to refute success, a method that anyone would find whimsical when they heard it, not to mention that everything was rigorous, and every plan had to find a scientist with theoretical support.

The fact that he succeeded in saying this with confidence was both confusing and relieved. Puzzled by how Earth could turn into a Noah's Ark, the alien Wedel reminds the Earthlings that they have thought of this and are helping out.

So he asked, "Now that we've found a way to lead Earth out of the solar system, why doesn't the Redeeming Light Organization get into action right away?" Maybe if we implement the plan now, the Earth will be out of danger before the outbreak of Arctic war? In this way, the catastrophic scenarios we have seen will not appear, and the Arctic continent will not become the last graveyard of civilization on Earth. Do you think that's the truth? ”

"Of course it is." Success does not deny his vision, but goes on to say, "As long as the materials that the Light of Salvation organization desperately needs can be found, the plan can be implemented." It's just that this material has never been successfully developed. ”

"Materials? What material? Hai Ge was stunned. In his opinion, even there are ways to escape, how can humans be stumped by such a "small" thing as materials? Even if you can't find what you need, can't you use a replacement? Furthermore, what kind of material is it used for?
