"The future of the new human race, after mastering the power of the gods, does not have an infinitely bright future and era. On the contrary, the new humanity is confronted with a catastrophe that has never existed before, and which is likely to be forever and infinitely close to the destruction of humanity itself.

"That is eternal life. ”

Lu Lie said curiously: "The pursuit of eternal life is not unique to you cows and horses, in our world, there are also emperors, Taoist priests, or something that pursue immortality or something, and practice a lot of pills." Why would the pursuit of eternal life destroy you?"

Li Yuan said: "First of all, you have to understand a concept - in the new human era after 150,000 years, immortality has been proven to be a feasible topic, countless scientists and mystics have spent a huge amount of time and energy, and a large number of consortia and federations have invested money, shares, and equipment to study this subject, which has been criticized by ancient scientists as ridiculous and funny.

But it was precisely this subject of eternal life that opened Pandora's box and set off the countdown to the destruction of humanity as a whole. ”

Li Yuan closed his eyes, and the entire history of mankind was frozen in the golden age of 4261, which was the era when the new human race reached its peak, and it was also the unprecedented strength of human beings since they were born in this vast universe. Countless ships and spaceships have been sent to the margins of the universe, planets have been colonized, and human activities have expanded from the small galaxy to the entire universe. At the same time, the physical problems of the human world have been solved, the three conjectures of the century have been given twelve solutions, and after the quark, mankind has discovered twelve smaller particles, and even the mythical perpetual motion machine has been created and widely used in various interstellar voyages.

It was in this context that Dr. Dax came up with the "theory of eternal life."

Dax's "theory of immortality" is very interesting because he is not an expert in the field of biology himself, and his understanding of immortality is not as simple as the traditional biology of infinitely lowering metabolism or transplanting brain and memory. Dax's understanding of eternal life proposes to create a logical cycle that cannot be explained by cause and effect in a limited space of low latitudes, because this paradox is connected and contradictory to each other, so as to destroy the causal chaos of the universe.

It's like the classic space-time paradox, where a timetraveler travels back in time and kills his grandfather before his father is born. So the question is, if his grandfather died before giving birth to his father, then it is equivalent to never giving birth to him, how did he go back in time and kill his grandfather?

What Dax has to do is to create the same artificial paradox, and this particular paradox is made up of countless thousands of small paradoxes after decades of careful calculations, like cogs to form a huge precision causal machine. Its complexity is thousands of times greater than that of the first paradox. In Dax's calculations, as long as this huge paradox is successfully created, it is enough to make the cause and effect of the universe unexplainable, and finally trap a human life in an endless cycle forever, so as to achieve the goal of "eternal life".

Lu Lie asked modestly, "What kind of-thing is that?"

Li Yuan had no choice but to continue to reduce the difficulty of the explanation of the theory of eternal life: "If the entire universe is compared to an examination paper, the cause and effect of the universe is compared to a teacher of papers. Then everything you and I do will be judged by cause and effect. If you are wounded, you will bleed, if you are killed, you will die, if you are hungry, you will eat, and when you are thirsty, it will be like drinking water. You won't starve to death if you eat when you're hungry, but you won't starve to death if you don't eat. Everything is sown for a cause and fruit. The law of cause and effect is irreversible, inviolable, and irresistible. Mortals can only obey it and plant relative causes according to the 'effect' they want.

And all Dax has to do is write something on the exam paper that cannot be understood. The law of cause and effect cannot explain the paradox created by Dax, just as the teacher cannot determine whether the question on the student's paper is correct or not, because the student has written something on the paper beyond the teacher's comprehension. ”

"So what?"

"The cause and effect of the universe will be distorted, and it will fall into a dead loop like a computer crashing. Then, as I said earlier, human life is trapped in a cycle of death forever, and Dax's purpose is achieved, and in this way eternal life is achieved. ”

This time, Lu Lie asked a question that he was bound to ask: "What is that...... Did he succeed in the end?"

Li Yuan gave a plausible answer: "He almost succeeded." Oh no...... It should be said that he has already succeeded. ”

"Almost succeeded? What does that mean? Can you stop answering these ambiguous things all the time?" Lu Lie noticed that the sun was setting faster and faster in the distance, and the blood-red sunset had gradually turned purple. He had no choice but to speed up his speech, "Also, why did this immortal experiment designed by the old wanderer called 'Da' almost wipe out all your new human beings? Could it be that this cosmic cause and effect can't explain the law of cause and effect he created, so in a fit of rage, the entire universe crashed and broke?"

Li Yuan had to patiently explain some basic common sense to him: "The paradox designed by Dax, even if it is extremely complex in the eyes of human beings and is the limit of human intelligence, but for the entire universe, it is just a drop in the ocean, and the universe will not perish because of such a small thing." ”

"Why? ”

"Because," Li Yuan said, "a certain link in Dax's paradox is to require the destruction of all the same kind in a certain period of time and space before him. ”

Killing billions of people for the sake of eternal life for one.

"When the Dax paradox was released, it caused an uproar throughout the new human world, and our world soon recognized the Dax paradox as a forbidden scientific theory. Dax was put on the death table, all his manuscripts and notes were destroyed, his family and students were sent to the deepest recesses of prison, and the people were so afraid of this mad scientist that his name became a taboo for the new humans for a long time.

But none of this stopped Dax's paradox.

"In the future, which is not so far away from us, that is, for our new humanity, we see that in the future, someone has achieved immortality using Dax's method.

In other words, the people of our plane are about to be destroyed. ”
