Chapter 60: Cause and effect of water control

　　 Huang Ji went to bed at twelve o'clock and got up at nine o'clock the next day.
　　 No way, he just has to sleep longer than others, because his mind is too tired...
　　 While asleep, he also had a dream.
　　In his dream, he seemed to see an elephant trampling on the farmland and eating the crops.
　　 The local farmers were very dissatisfied, so they dug traps near the farmland to lure the elephants into stepping into the pit.
　　 In the end, it was apparent that the elephant was killed by the farmers.
　　 And this is the last elephant in Henan Province. After that, the Central Plains elephant became extinct.
　　 Huang Ji woke up, played a set of Nei Jing, from the first group to the fourth group, all practiced.
　　 then brushed his teeth and washed his face, and came to the front hall.
　　 I saw Lin Li sleeping on the carpet in the front hall, without asking him, Huang Ji also knew that he stayed up late last night and did not sleep until dawn.
　　 There is not much improvement, that is, I succeeded twice again, but because of this staying up late, I lost 20 hours of life...
　　 Huang Ji shook his head, did not wake him up, and went out to buy early.
　　 came back and sat on the sofa, drinking porridge and eating eggs, he continued reading.
　　 "I dreamed of an elephant in the Central Plains, yes, that was the last historical record I saw before I went to bed."
　　In the past, there were many elephants in Yu Province, and it can even be said that elephants ran all over the place...
　　 Before Huang Ji went to bed, he saw a document, which was recorded in the early years of the Northern Song Dynasty, where farmers killed elephants.
　　 This... is also the last wild elephant in the history of Henan Province.
　　 After more than a thousand years, there will be no wild elephants in the north.
　　 "Why did the Central Plains elephant become extinct?" Huang Ji looked through the history books and couldn't help but infer the answer to this question.
　　 There is no doubt that mankind must have been extinct, but Huang Ji wants to deduce a more detailed historical process.
　　 Once he succeeds, the past tense information will be unlocked, so that it can go back to the past, see through the historical development of everything, and reverse the past.
　　 "Although the last elephant died in the early Northern Song Dynasty, there were basically no wild elephants in the north as early as the Han Dynasty."
　　 "The famous Cao Chong called the elephant, and it was also the tribute of the elephant that Sun Quan in the south found from the Guangxi and Guangxi. Obviously at that time, even if there were elephants in the north, they were already critically endangered and remained deep in the mountains and forests of Henan Province."
"Lu's Spring and Autumn Records recorded that'merchants served elephants in order to abuse Dongyi. Zhougong chased them with his division, as for Jiangnan.' During the war between Yin and Zhou, elephant soldiers had been developed. At that time, there were still many elephants in the Central Plains. "
"However, the Yin Shang hunted and killed a large number of wild elephants. Anyang Yin Ruins unearthed a large number of ivory and ivory products. When there is trade, there will be killing. Wild elephants were hunted and killed in large numbers during the Shang Dynasty, and then they were expelled by Zhou Gong to the south. Except for the deep mountains and forests, there are almost no elephants in Henan Province, and they are on the verge of extinction. Once they are found, they will be hunted and killed. Wouldn't they be completely extinct?
　　 Huang Ji thinks that the derivation is no problem. The Central Plains elephant was extinct because of human indiscriminate hunting.
　　 The root of everything lies in the Yin merchants’ love for ivory, so that there are only two or three big cats and kittens left in the Central Plains elephants that were originally all over Henan.
　　 However, Huang Ji did not find that the past tense was unlocked.
　　 This means that he used the wrong concept or the derivation was completely wrong.
　　 "Is it wrong?"
　　 Huang Ji tilted his head, the Central Plains elephant was not extinct because of human indiscriminate hunting?
　　 It’s not wrong to think of it like this...Earlier, there was a legend of Emperor Shun serving elephants:
Shun cultivated in Lishan. There are elephants for ploughing, and birds for ploughing.

　　 Could it be that in the era when elephants could cultivate land, they had already begun to hunt wildly?
　　 Huang Ji thought, trying to deduce that the Central Plains elephants had been hunted and killed in large numbers in the ancient times, and they were becoming endangered.
　　 But... still wrong!
　　 Huang Ji frowned. He could have a better derivation, but he chose to derive this.
　　 He still doesn't believe it. Is it so difficult to deduce the extinction of an elephant?
　　 Then, until one o'clock in the afternoon, he failed to deduce the correct answer.
　　 "How did the elephant become extinct?" Huang Ji closed his eyes and thought hard.
　　Don't say the correct answer, in fact, as long as the concept used is correct, the process is basically correct, and the result is almost correct, then it can be unlocked.
　　 This is his experience of unlocking the futuristic state, but after trying various results, he has never been able to unlock it.
　　 means that there is a fundamental problem with the derivation.
　　 "Big Brother?" Lin Li stretched and woke up, seemingly startled by Huang Ji.
　　 "You said, how did the elephants in Henan become extinct?" Huang Ji asked him casually.
　　 Lin Li stunned: "Huh? There are elephants in Henan? Are they not in Africa and Southeast Asia?"
　　 "...Forget it, let's go out to eat." Huang Ji said.
　　 Huang Ji should think about curing his illness. After lunch, he took Lin Li on the street looking for something, and soon he found the information he wanted.
　　 It was a telephone pole with various small advertisements plastered on it.
　　 What can finally be saved, what money to ask for a child, what to look for a dog notice, everything.
Huang Ji pointed to the bottom of the telephone pole, a very inconspicuous, only the size of a business card's'Graduation Certificate, Qualification Certificate' advertising sticker, said: "You can contact this person, help me get a diploma, and Medical qualification certificate."
　　 Lin Li nodded and pointed to the telephone pole, at the height of the face, a particularly eye-catching advertisement that was also a fake certificate, and said: "Why not contact this company?"
　　 "You can see that his introduction is more detailed, and the advertising paper is larger than the others, and the location is very eye-catching. At first glance, it is the industry elite in the fake certificate..."
　　 After hearing this, Huang Ji on the side laughed dumbly.
　　 Lin Li thinks that the bigger and more prominent the post of this kind of small advertisement, the more capable it will be.
　　 But this is obviously a typical misunderstanding of thinking. It is totally unreasonable after careful consideration.
　　 "Is it right?" Lin Li couldn't help asking when seeing Huang Ji laugh.
Huang Ji smiled and said: "The person who posted this advertisement really took the best position. The paper used is larger than others. Maybe check it every day. If you find that it is covered or torn off by your peers, Post it again, so we come here at any time, it may be in the best position."
　　 "But this can only mean that his advertising technology is better than others, and he can promote it. What does it have to do with his ability to issue false certificates? Not to mention industry elites."
　　 "I even think he is not influential!"
　　 Lin Li scratched his head, don't know what to do.
　　 Huang Ji said: "Let's put it this way, someone who posted such a good advertisement for a fake certificate has probably been arrested..."
　　 "This..." Lin Li was taken aback, and then suddenly.
　　 The advertisement is played so well, and the tree is so popular. Maybe the business is better than others for a while, but it is a violation after all and it will not last long.
　　 is such a high profile, even if it is not caught now, I am afraid it will be soon.
　　 In comparison, sticking your own small advertisements in an inconspicuous place is the real evergreen in the industry and the old fritters.
　　 Even if it takes a long time to wait for a guest, it doesn’t matter, the win is stable, and you can eat repeat customers and use them to attract new guests.
　　 The purpose of posting a small advertisement is just to get the first guest.
　　 Those who can do this must be very confident in their own technology, otherwise how to eat?
　　 Conversely, people who work publicity may be a manifestation of technical unconfidence.
Huang Ji said: "What's the use of large stickers? What's the use of even good technology? No matter how good the technology is to apply for a fake certificate, the police and the police will not catch it? Good business, big trees attract wind and die faster, and long water flows are king. "
　　 Speaking of this, he himself was taken aback.
　　 Lin Li was still nodding, but Huang Ji slapped him on the shoulder.
"Yeah... Large, powerful, and diverse species are not successful. Only if you live long can you really succeed. If you want to live long, you must adapt to the environment." Huang Ji said, he thought of the problem. Where is it?
　　 Lin Li blinked and said, "Huh? Is it possible to get a fake certificate to survive the fittest?"
　　 "There is no survival of the fittest, only the survival of the fittest." Huang Ji corrected: "The success of a species does not lie in whether it is strong or not. You can't beat me, but can I say that you are inferior?"
　　 "On the contrary, the species that occupy the higher niche are more likely to become extinct because it is difficult for them to adapt to the environment!"
"Dinosaurs are powerful enough to occupy the upper-middle ecological niche, and the mammalian ancestors were very weak at the time, located at the bottom of the food chain. But after a disaster, all dinosaurs became extinct, and the weak mammalian ancestors survived. Who do you say Who is better?"
　　 Lin Li scratched his head and said, "Yes...I remembered, brother, but what are you telling me about this?"
　　 "Nothing..." Huang Ji smiled and began to deduct the extinction of the Central Plains elephant.
　　 In the early years of the Northern Song Dynasty, when a large number of mountains were developed and woodlands were cut down, the wild elephants had nowhere to find food or hide, they could only break into human habitats to eat crops.
　　 provoked humans, no doubt, death.
　　 This is the reason for the death of the last elephant. It is not human beings to kill, but the environment forced it.
　　Yin merchants are really good at killing, hunting a large number of wild elephants to obtain ivory, but they have not killed the wild elephants for hundreds of years, which shows that they are also breeding or hunting in a regular and controlled manner.
Henan Province was one of the most suitable places for agriculture at that time. Zhou Gong did not choose to kill the enemy's war elephants, but expelled them to the south. The reason for the expulsion was to prevent elephants from trampling on the farmland. At that time, Henan Province had been extensively developed. , Not enough to feed so many wild elephants.
　　 "The change in the environment is probably due to human beings, but it is definitely not in line with the attitude of exploring history to combine the clues in the literature on this premise."
　　 "The extinction of the Central Plains elephant was due to the disappearance of habitat. Most of the habitat disappearance was caused by humans, but it was due to the development of agriculture."
　　 "No, agriculture is only a later process. It was the Yellow River that caused the mass migration and death of elephant herds earlier!"
　　 Mingming Huang Ji is also a top expert in the field of biology, but when deducing the extinction process of a species, he did not consider the impact of the environment on the species.
　　 It is true that he has just mastered the research methods of historians, so he wants to find clues in the literature.
　　 As everyone knows, light literature has a fart. The historical process of deducing a thing must be considered from all aspects. The more knowledge used, the closer the result is to reality.
　　A mere historian cannot test ancient times. All top archaeologists are also biologists and geologists...even anthropologists.
　　 When Huang Ji became clear about this, the past tense of the message was opened.
　　 "Concrete floor?" Huang Ji turned his head and walked into the nearby park.
　　 In the park, he looked at the ground under his feet, where he was standing, time seemed to be flowing backwards, he was tracing its past!
　　 "Hiss..." Huang Ji felt that his brain couldn't bear it, and quickly blocked most of the information.
　　 He doesn't want anything else, only accepts geological information, so the pressure is alleviated.
　　One hundred years...Two hundred years...One thousand years...Two thousand years...Two thousand five hundred years...This is the capital of Korea.
　　 "Hi, uh! Even if you only accept geological information, won't it work in two thousand five hundred years? There is a geological change in two thousand five hundred years!"
　　 Yellow pole shielded it, and then the pressure disappeared.
　　 "Huh?" Huang Ji soon discovered that he could trace back to the ancients, but the content was blocked.
　　 When rehearsing the future, the reason why it is difficult to go back too long is because time is passing and changing every moment, so Huang Ji is suffering from shocks every moment, and the duration of the rehearsal opening is very short, so he gets dizzy.
　　 But the past tense of information will not change!
　　History is history, even if the earth is destroyed now, history is like that. Information that will not change, perception is like this today, and perception will remain the same tomorrow!
　　 So he doesn't need to worry at all. History will not change anyway. He pushed back thousands of years in the shielded state, and then lifted the shield without any pressure at all.
　　 Don’t talk about thousands of years, it’s okay to reverse push billions of years. The duration of reverse push is unlimited, as long as you don’t receive information continuously for a long time.
　　History is there, he is just inquiring, not deducing. This is different from the future state.
　　 The only limit to him is the amount of information. He can only check the context roughly. If he knows too many more detailed details in a short time, he will be dizzy.
　　 Huang Ji closed his eyes and soon felt that four thousand years ago, there was a piece of land here!
　　 The place where he is, all the five senses around him is flood! The waves flooded this place directly!
　　 "Just look at the geology and you can't see anything, so let's open it up..." Huang Ji lifted the shield, and for a while felt a severe headache.
　　 But correspondingly, he also knew what was going on with that flood...
　　 3,950 years ago, the upper reaches of the Yellow River encountered an earthquake, forming a natural flood storage dam. After half a year, the dam suddenly broke, and the middle and lower reaches were flooded.
　　 Huang Ji kept doing micro-manipulations. In order to ensure that he could withstand the pressure, he searched for some information purposefully. If he didn't want to know it for the time being, he would block all the information. If he wanted to know, he would open any information.
　　 Repeatedly, he gradually understood the true cause of the extinction of the Central Plains elephant.
　　 The flood was intermittent, lasting for forty-two years periodically, and even destroyed many small ancient countries.
　　 The people in the middle and lower reaches of the river are in dire straits, and civilization has been severely damaged. Just under his feet, there is an ancient city buried in flood, cement and sand.
　　 The Yellow River passes through Xinzheng. It is conceivable that the entire Henan province is densely covered with water networks and will almost certainly overflow in the rainy season.
　　 "The old river was washed away, the floods were intermittent, retreating and coming, coming and retreating...People are eager to manage it."
　　 "So after forty-two years, three generations, and finally in the hands of Dayu, people finally managed it."
　　 For their own survival, the people in this area followed the mountains and rivers, dug rivers, dredged the floods, and adapted to the disaster.
　　Humans are species that actively transform nature. This wisdom is also part of human adaptation to the environment, but they have adapted, and some of the animals that originally lived in the Yellow River basin have become extinct.
　　 The mutation of the ecological environment will cause some species that cannot adapt to the extinction. The higher the niche, the more difficult it is for the species to adapt to the mutation of the external environment.
　　Central Plains elephants, they were once at the top of the food chain. They have no natural enemies unless they are human.
　　The flood has a great impact on human beings. The same is true for elephants, which directly led to the death of a large number of wild elephants.
　　 But this will not make them extinct. What really makes wild elephants critically endangered is Dayu's water control!
　　 Dayu dredged the waterway, diverted the Yellow River and sent it to the north... making most of the entire Henan Province located in the south of the river.
　　 This is not the point. The point is that he opened up mountains and drained rivers and dug a large number of tributaries manually, destroying many animal habitats...
　　 Natural disasters and man-made disasters have carried out multiple attacks on wild elephants in 42 years, and the environment has changed drastically.
　　The wild elephants have been baptized by two waves in succession. They still survived tenaciously, but they ushered in the third wave of chronic blows... Agricultural development...
　　 Dayu's water control is undoubtedly a huge help to the development of agriculture. By the artificially excavated river, humans have established their own new gathering areas and let tributaries irrigate farmland. This kind of water conservancy project has made agriculture advance by leaps and bounds.
　　 But this is not good for wild elephants, but it gives them despair, because they have lost a large water source, and elephants have to drink a lot of water every day.
　　 It is impossible for humans to allow them to approach the river that irrigates the farmland. It took them three generations to approach the water conservancy project that was finally built...
At this point, Dayu ruled the waters and deployed the Jiuzhou, and designated the southern part of the river as "Yuzhou". On the fertile plains of Yuzhou where wild elephants were running everywhere, there were no traces of wild elephants, except for those who migrated. Exist in the forest until extinction.
　　 Huang Ji never expected: "Dayu, it was you..."
　　 "This is nature. To save our compatriots, we must harm other species. If someone cheers, someone will cry."
