Of course, the photographer knows the meaning of mark recapture method, which is a very limited estimation method.


    For a simple example, if you want to know how many fish there are in a pond, you can catch several, then paint all these fish, and then put them back in the pond.


    Wait for a period of time, fully mix the fish, and then fish. Count the proportion of dyed fish in each fishing, plus how many dyed fish have been known. You can simply estimate how many fish there are in the pond.


    This method was once widely used to estimate the number of wild animals. Tulips often used a similar method to estimate data in the early stage, so what did the filmmaker think of immediately after the ice emperor mentioned the word?


    "What do you mean? Is anyone using this method to estimate the overall number of infected people? "


    "Yes, and it''s normal, isn''t it? Even without considering the possibility of their planned exposure, it is necessary to regularly count the number of infected people. The reconnaissance plane can''t make accurate statistics. Does this method become a convenient and fast statistical method? " The ice emperor was elated. She finally reacted faster than the film.


    "It''s really troublesome to say so. This statistical method can directly see through the disguise of infection." Shadow frown.


    If it is other estimation methods, it is likely to be cheated by infection. However, the seemingly primitive method of mark recapture can not be fooled by the infected people.


    Infected people may not know that someone has been secretly marked. Therefore, when assigning people left on the surface, they will not consider whether they have been marked, that is, they are basically random. In this way, the proportion of marked people on the surface and underground should be similar.


    Therefore, even if only the number of people on the surface is counted, the total number of infected people can be estimated.


    At the same time, in the sky


    The fighter driven by soul force flew at high altitude, and the pilot controlled the fighter to hover at high altitude: "yak! You can show me clearly this time. Last time you told me that only one of the 100 people was marked, and we were almost scolded to death by the fat woman.


    If you count wrong again this time, I''m afraid our fighters will be confiscated. In the future, we can only fly in the countryside to spray pesticides. "


    The fighter fire control called yak has two white, four yellow, two purple, eight soul rings, and his eyes turn ice blue. This kind of soul ring configuration is quite high in this era.


    After all, it''s slow. There are too many people. Almost all the people can become soul masters. Where can there be so many soul animals in the soul animal farm. As we all know, even in China on earth, the annual pork consumption per person is only about 30 kilograms. This amount is already the first in the world. It can be imagined that a person eats pork all his life. Ten pigs at most.


    The national living standard of Tiandou empire is far worse than that of China. Even if it can be compared, and using soul animals as the source of all meat, the average soul ring that everyone can get in a lifetime is only ten white soul rings, while a yellow Centennial Soul Ring needs at least ten ten years to be synthesized. It can be imagined that even if everyone has a talent for cultivation, it is impossible to allocate soul rings.


    Soul Douluo is not a high-end combat force at the national level, but his status in civil society is almost the same as that of ordinary enterprise bosses, not to mention his martial soul is a precious noumenon martial soul, with amazing eyesight.


    "Don''t make a noise. I saw it clearly. There was absolutely no wrong count last time. The old woman was jealous of our youth and deliberately gave us small shoes.


    I didn''t count wrong this time. In total, we found a mark. There are 153 people in this area. The number of people marked accounts for absolutely less than 1% of the infected people.


    Even if the fat woman intimidates me, I won''t change the report again. I really think I''m scared. The big deal is to change jobs. Who''s afraid of who? "


    "Yes, I''ve had enough of that fat woman. I hope someone will replace him as soon as possible. In other words, you''re right to count this time. If it''s less than 1%, the infected people will be up to 300000. At the beginning, we marked 3000 people. " The driver said.


    "Who knows, maybe the marks of infected people were pulled out when they shit. Or maybe the infected people who were marked died, or maybe there were 300000 people.


    Whatever, the number of infected people is not a headache for us. How to deal with it? Just throw it to the big people above to quarrel. Let''s just do our own thing. Just in case we fly again. " Yak didn''t care.


    "It''s because you''re so honest. I''ve always been a field pilot. If I had your talent. I''ve been lying in the office soaking medlar water for a long time. "


    "Yes! Then you''ll boil into the Mediterranean and drink out of your stomach! Hurry up, although officials say there is no radiation in the high air. But only silly x will believe the official nonsense. I don''t want to be infected with crystal disease. " Yak stared at the infected people below and silently counted their number in his heart.


    He is still young, and the future can be said to be bright. In this era, the original powerful animal spirits have declined, and those spirits often make the body of the spirits use a significant variation.


    For example, the limbs swell and grow brown hair or scales. It''s easy to grow tails, ears, or claws in the Xingluo Empire, because the armor of the strong is tailor-made armor.


    But in Tiandou Empire, it''s very troublesome. Everyone''s mecha comes down from the standard assembly line. You can find an extra pair of ears. When wearing a helmet, you must fold down the four channels on your head. If you have a long tail, you have to tie your waist. If you have a pair of wings, you can basically say goodbye to the mecha.


    In contrast, Wuhun has become the son of the version, especially those auxiliary Wuhun. Their bodies basically don''t have any variation. There''s no problem driving standard mecha. As for martial spirit, it''s an item anyway. You can put it anywhere. Some match the mecha. It can even be held in hand between mecha.


    Although yak was only the fire controller of the fighter, he was expelled from the mecha Corps only because he had a bad mouth and offended his boss. No, he obviously didn''t learn the lesson of last time. He still doesn''t intend to compromise with his boss and is ready to report the report truthfully. Of course, the reason why he doesn''t compromise is that his boss is a fat woman. If he changes to a beautiful woman, the battle of the first infected person may be another outcome.
