Cui Lingfeng is silent. His lips are as strong as the gate of the Starship facing the cosmic vacuum.


    Tang Dingyuan glanced at Li Yao, his eyes more sternly, and his anger slowly accumulated: "first, the ''Honglian plan'', and now there is a ''rebirth plan''. How many things are there on this ship that I don''t know?"


    "A lot."


    Cui Lingfeng said, "you are the captain of the firefly. The captain must be fearless, brave and brave! You don''t have to know everything


    "I want to know."


    Tang Dingyuan stares at Cui Lingfeng''s eyes, word by word, calmly but firmly says, "if you don''t say it, let Ding Zhengyang say it."


    Cui Lingfeng''s lips, the gate sealed with countless secrets, trembled for a long time, and finally said: "in the past 1000 years, we have encountered countless difficulties and dangers, and we have formulated emergency plans for all the situations. The" rebirth plan "is aimed at the most serious, dangerous and fatal" super crisis "situation, The emergency plan formulated. "


    "I''ve never heard of any ''super crisis situation''," Tang Dingyuan said slightly stunned. "The ''first level crisis situation'' is already the highest level."


    Cui Lingfeng said with a smile: "no, the first level is not the highest, but the super level. The so-called" super level crisis "means that the resources on board for survival and escape are less than one fifth of the standard. The circulation system and man-made greenhouse have been seriously damaged, and the follow-up resources will not be able to rise to half of the standard within 50 years, or even will continue to decrease, Our civilization will collapse in 50 years and be completely extinct in 100 years. Oh, this is still an ideal state. In fact, because of human survival instinct and all kinds of crazy actions before death, once everyone knows that we will perish in 50 to 100 years, it will not take so long. At most, in five years, the social order will completely collapse, and in ten years, The firefly of civilization on this ship will be completely extinguished.


    Once the speaker is aware of this situation, he has the power and must start the "rebirth plan" to reduce the population on board rapidly, efficiently and steadily until a balance is reached between the sustainable recovery of population and resources.


    Tang Dingyuan''s voice began to tremble: "how, how to ''reduce the population''


    Cui Lingfeng said: "do you know the meteorite and ice rain attack that firefly suffered 728 years ago? The meteoric ice rain itself is not serious. It just broke through the outer shell of our outer star ship. However, the meteoric ice carries strange viruses, causing a great plague inside the firefly, reducing our population by 20 percent. "


    "Of course, it was almost the hardest and darkest time for firefly."


    Tang Dingyuan doubts a way, "but isn''t that pestilence put out completely by us?"


    "Yes, the plague has been put out, but the virus has not been completely destroyed."


    Cui Lingfeng laughs strangely, "it''s a perfect virus. It has many mutations and spreads quickly through the air. The symptoms are not obvious and the incubation period is uncertain. Once it attacks, it will be extremely lethal. It will automatically find the strongest host to infect first. The more powerful the host is, the faster the mutation and erosion will be, This can counteract the host''s efforts to use psionic self-treatment. In other words, this is a kind of "equal treatment" virus. No matter ordinary people or practitioners can escape from it, and the mortality rate is almost the same.


    Our virologists conducted in-depth research on it in the laboratory. At the beginning, their idea was to refine a kind of virus weapon to attack the Empire. But later, they found that it had a fatal weakness, which could be easily prevented and treated by a kind of synthetic medicine. The materials for synthesizing this kind of Medicine were produced all over the world, and the synthetic method was not too complicated.


    In other words, even if the virus weapons are really refined, it is difficult to cause a serious blow to the Empire. At most, they can wreak havoc on one or two of their star ships for a while, which is not of great military significance.


    But this kind of special medicine... On our ship, it is very difficult to refine in large quantities.


    As a result, experts hundreds of years ago began to refine virus weapons for a new purpose, and the final results are very satisfactory. It has the characteristics of fast transmission, hidden symptoms and strong lethality. At the same time, it is aimed at practitioners and ordinary people. Once it spreads through the air circulation system inside the sealed starship, it can quietly and instantly reduce a large number of people. The most important thing is that, It has what we call a "Half-Life" feature. As long as it spreads for several generations, it will automatically annihilate and will not continue to spread.


    And this half-life is controllable, can be long or short.


    In other words, this is a kind of "precision strike" virus weapon. As long as you control the length of half-life and know the total population available for infection, you can calculate in advance how many people it can kill. After the death toll reaches the standard, it will also collapse and annihilate, leaving no sequelae.


    This virus is named "rebirth virus". It is the key to the rebirth plan and may bring rebirth to the endangered firefly


    Tang Dingyuan couldn''t believe his ears and looked at Cui Lingfeng for a long time: "you, you have secretly developed a kind of virus weapon, which is not used to deal with the enemy, but to kill your own people, your compatriots, and the people you have vowed to protect! What''s the difference between you and those who cultivate immortals? "


    "Yes."


    Cui Lingfeng said calmly, "suppose you are an immortal who is responsible for implementing the" rebirth plan ". Think about it. What would you do? Of course, it is to isolate the cabins of ordinary people, that is, the humble "original people", from the cabins of the immortal cultivators, that is, the "real people", and only put the virus in the original people''s cabins; Or let all the immortals take the special medicine in advance; Even in the refining stage of the virus weapon, we try to weaken its attack on the awakened spiritual root, so as to only infect ordinary people, not the immortal practitioners, right?


    After all, in the eyes of immortals, ordinary people are garbage people, which is a useless burden. Since resources are insufficient, it is natural to reduce the number of garbage people.


    But we didn''t implement it like this. I can decrypt all the implementation plans of the rebirth plan to you. We didn''t plan to isolate everyone or let anyone take the specific medicine in advance. Even, for the sake of insurance, our ancestors have already destroyed all the specific medicine and the materials that can extract the medicine.


    Once I decide to put in the virus, the virus will instantly spread on the whole firefly and kill its favorite prey randomly. No one can be spared. No matter the practitioners or ordinary people, or even myself, may be infected and eventually die.


    Do you understand that the ancestors who made this decision did not regard themselves as the "Superman" who could decide the life and death of "mortals"? No matter the practitioners or ordinary people, they all listen to the judgment of fate. Many people will die, but more people will carry their burden and continue to move forward in... The Dark Universe.


    It''s good to say that the ancestors who drew up the "rebirth plan" were deceiving themselves, but I think that''s probably what they are... The biggest difference between us and the immortals. "


    Tang Dingyuan''s heart beat and breath became extremely difficult. The upper and lower rows of teeth clenched so hard that people felt that even if there was a star ship in his mouth, he could chew it up: "no matter how you explain, I still can''t accept it, absolutely can''t!"


    "Well, brother Dingyuan, what should you do?"


    Cui Lingfeng sighed and said, "suppose now, as the captain, you know very well that the resources on the ship are only enough for 100 people to survive, but we have 200 people, 200 hungry mouths and never full bellies. What would you do?"


    Tang Dingyuan was lost in thought, speechless, and his voice was much lower: "a true practitioner, a true practitioner should not be so, so..."


    "If you think that practitioners should not be so dark."


    Cui Lingfeng said faintly, "it''s just because someone stands in front of you and helps you to do these dark, dirty and cruel things, my captain."


    Inside the cell, Ding Zhengyang gave out a "quack" laugh like a crow: "Captain, do you know the truth of the" rebirth plan "? Is your mind all right! Can you tell me that the guy who can draw up such a plan is still a real cultivator? No, I''m not the first one to cultivate immortals on the firefly. There have been immortals on this ship for a long time, and they have occupied me! "


    Cui Ling said coldly: "Ding Zhengyang, we didn''t implement the" rebirth plan "until the end, and the firefly survived."


    "Yes, you survived, but it''s just because you''re lucky enough not to encounter a" super crisis. "


    Ding Zhengyang said with a smile, "but luck won''t be so good forever. If we don''t meet the imperial claw fleet and the Xingyao Federation, the firefly will continue to drift towards the depths of the sea of stars and the unknown places where people rarely visit. With the gradual aging of the starship, the" super crisis "will certainly happen within a few hundred years!


    Don''t argue with me about this. I''m the first mate. I know every thread of every screw on this ship like the back of my hand!


    That is to say, within a few hundred years, even if the Empire did not catch the firefly, the firefly itself would be swallowed by the darkness and become a little "immortal civilization"!


    Do you understand? One day, we will all become immortals. I just... Took a step first!


    This is Lu Qingchen''s theory. The cultivator is just a "special variant form" in a stable environment with abundant resources. However, in the dark universe, the lack of resources and drastic changes in the environment are the norm. Therefore, the cultivator is the general manifestation of "Superman."
