After listening to Wang Bin''s words, Lao Huang was silent. In fact, he also wanted to suggest to his superiors and drive dukao and others away directly, but now it seems that he can''t. moreover, he knows that his superiors know much more than he does, and he can see things more thoroughly. Therefore, he doesn''t think much about this matter anymore.

    Instead, he put his heart back to his purpose of coming here this time. The purpose of his coming here this time is very simple, that is, to come to Wang Bin''s Tiangong technology store, in addition to asking about things, he is also ready to buy special glass and bearings in their Tiangong technology store.

    After all, now that they know that in the near future, extraterrestrial civilization will come to the earth, human civilization must be prepared as soon as possible.

    So he asked Wang Bin again, "shopkeeper! Since you know that alien civilization will come to the earth in the near future, I think you must know the situation of alien civilization in terms of force. I hope you can tell me!"

    After listening to Lao Huang''s words, Wang Bin thought for a moment. Obviously, according to the rules of the system, their real strength of supernatural universe, gourmet civilization and giant wolf civilization can never be said, but some things are not without loopholes.

    So Wang Bin said, "I can''t tell you the real civilization level of aliens in your world, but you can judge the strength of alien civilization in your world according to the civilization level.

    First of all, since the civilization preparing to invade the earth has the ability of long-distance interstellar navigation, their civilization level has definitely reached the level above the level of first-class civilization even through ingenious means.

    As for the standard of first-class civilization, I think Lao Huang, as a plane businessman, you do not need me to say that you know that you can use all the energy of the parent planet of the civilization and operate all the weather changes, earthquakes, tsunamis and so on.

    At the same time, when the civilization level reaches this level, it also has a certain Aerospace capability. However, the spacecraft of this level obviously does not have the ability to navigate at the speed of sublight and superluminal, or the fastest speed of its spacecraft will never exceed 50% of the speed of light. Although the life span and physical strength of this level of civilization are high to a certain extent There are many zero level civilizations, but they are still very limited. They should not exceed ten times their own life span and physical strength.

    In other words, when civilization is at this level, if it does not rely on the long-distance wormholes naturally existing in the universe or built by higher-level civilizations, it cannot carry out real interstellar voyage, and its maximum activity range will never exceed 100 light-years of the galaxy where its parent star is located.

    Therefore, the human civilization in your world is likely to be invaded by such a level of civilization.

    Next, let''s talk about the secondary civilization, that is, the stellar civilization. If the civilization level reaches this level, the civilization can use all the energy in the planetary system where the civilization is located, including the energy emitted by the sun. The physical strength and life of individuals in the civilization have been greatly improved compared with those in the primary civilization.

    However, it is still impossible to break through a hundred times the original life span of its civilized individuals. As far as our human civilization is concerned, if there is no disease and other problems, the life span of human civilization can live for about 150 years at most. Therefore, if the civilization level of human civilization reaches the level of second-class civilization, the life span will also be increased to about 15000 years. Similarly, the physical strength is also relative to grade zero About a hundred times that of Ming.

    Therefore, the civilization that will come to the earth in the future may also be this level of civilization.

    Then there is the third level civilization. The third level civilization can also be called Galaxy civilization. To this extent, its spacecraft can fly at the speed of light, such as curvature flight, the construction of big bug bridge, and even praise Galaxy level star gates.

    At this level of civilization, the individuals of the civilization have been difficult to kill, and their life span has been almost unlimited.

    In other words, when the civilization level reaches this level, life will no longer bother them. They have unlimited time to improve their civilization level.

    At the same time, when civilization reaches this level, they can use all the energy in their large galaxy, including direct extraction of energy from stars, supernovae, neutron stars and even black holes, to serve their civilization.

    So when civilization reaches this level, it is basically no longer possible to invade a primitive civilization that has not even gone out of its parent star.

    Based on the above, together with the probability of the birth of civilization in the universe and the possibility of civilization developing to more than level 1, we can judge that there are not many level 1 to level 2 civilizations in the Milky way of our two universes. There are definitely hundreds of such civilizations in the whole Milky way, and there are far fewer civilizations between level 2 and level 3. According to the probability, the whole galaxy is far less In the Milky way, the number of civilizations above level 2 will never be less than two hands, while the number of civilizations above level 3 is even less. Even the whole Milky way does not include affiliated galaxies.

    Therefore, we are basically sure that the civilization level of these civilizations that will come to the earth in the future cannot exceed level 3, or even level 2.6.

    When the civilization level reaches level 2.6, they have understood the direction of their civilization. At this time, they have begun to improve their civilization level wholeheartedly, and will not take care of the ups and downs in the universe at all.

    Then how should we judge between level 1 civilization and level 2.5 civilization? Which level of civilization will come to the earth?

    First of all, we can exclude the level between 1.0 and 1.8 civilizations. Not to mention others, just in terms of aerospace ability, individual life span and physical strength, it is doomed that they are unable to carry out space war at all.

    Moreover, according to our human civilization''s exploration of the universe, there is no alien civilization within 100 light-years centered on the solar system.

    In other words, the alien civilization that will come to your world earth in the future also comes from a place at least 100 light-years away, so the other party''s civilization level will definitely exceed level 1.8 civilization. According to what we said before, we can confirm that the civilization that will come to the earth will be between level 1.8 and 2.5 civilization. "

    When Wang Bin said this, he was already a little thirsty, so he stopped, picked up a glass of boiled water from his counter and drank it.

    At the same time, I thought to myself that fortunately, the operator is allowed to bring some of his own life support items and some of his personal items to the stores of the science and technology mall. Otherwise, even drinking water can only return to reality.

    At this time, Lao Huang saw that Wang Bin stopped and didn''t speak. Instead, he quietly thought about Wang Bin''s analysis and judged the possibility. However, according to the civilization level he learned from the mall and the actual situation, he found that just as Wang Bin analyzed, The aliens who will come to their world earth civilization are likely to be civilizations between levels 1.8 and 2.5.
