The process of domesticating pandas is much easier than expected. Under normal circumstances, it takes a long time for wild animals to obey humans. But the undertaker used some opportunistic means to omit this process.


    He has gradually learned to control his hormone secretion, and he can not only secrete his own hormones, but also synthesize those of other animals. What would have taken a long time to establish is subject to conditioned reflex. Under his hormone control, it was finished in a few days.


    There were some rebellious pandas. One by one becomes extremely obedient, because obeying human orders will bring them great pleasure. Disobeying orders will make them very painful.


    In the future, we only need to catch new pandas and raise them together with the domesticated pandas, so we can cultivate more mounts based on this template.


    With transportation tools, migration is imperative. On the one hand, if you don''t plant it, the surrounding bamboo will soon be eaten up. On the other hand, Liu Tianxin has just killed a group of 10000 ethnic groups. Next, the tribe is likely to face retaliation. Leaving is the best choice.


    This is why Chengying reluctantly gave up farming and chose nomadism, fishing and hunting. Human tribes fixed in one place will undoubtedly be bullied by thousands of nationalities again and again. It is difficult to develop.


    Only continuous migration can spread civilization and technology. In order to make progress for the whole of mankind, we should first find a way to evolve from primitive society to nomadic tribes.


    Although the nomadic tribes were low forced, they were hanged and beaten by various farming tribes with the same territorial technology. But compared with the hunting and gathering in primitive society, it is still too advanced. At least surplus products have been born in society, and the concept of private ownership can appear. Transactions can occur. There can be surplus labor. It can sprout the most basic handicraft industry.


    It''s nothing for a small tribe of thousands to come to this step. But if it is the whole continent, I do not know how many billion people have come to this step. The progress that that brings is absolutely huge. Human tribes will gradually annex each other. Surplus value and surplus labor force will be gathered. Various countries have gradually emerged and different orders have sprouted, and this is the opportunity for the germination of scientific thinking.


    Although all this will take a long time. There must be countless human tribes in the process. Persecuted by all races and extinct. However, Chengying believes that this change is unstoppable. Unless the fire of all civilizations is killed and all mankind is slaughtered, the fire of civilization will continue.


    Although his ideal is great, it is a pity that he has only more than 1000 people and more than 1500 pandas on hand. In addition to migration, they also need to find a livestock that can be used as a source of meat.


    It doesn''t seem difficult. Cattle are a very suitable choice, especially cattle in the wasteland. It seems that there are still many variations. It''s not difficult to find a variety that grows meat very fast.


    In fact, horses are the best means to enhance human combat effectiveness. But he knows very well that it is of little significance to enhance combat effectiveness at this stage. Even if cavalry are trained, thousands of them are needed to fight against a few extraordinary people, let alone challenge saints.


    The most important thing at this stage is survivability. What he has to do is to cultivate human civilization like weeds. No matter how devastating the blow is, it can reappear in the spring breeze.


    Cattle are very suitable as livestock. Slow speed is indeed the disadvantage of cattle, but they are stronger than horses in endurance and strength, and the meat quality should be more delicious.


    In the process of migration, you can pull carts and carry materials at the same speed as the pandas. When you arrive at the next settlement, you can cultivate land quickly. Although you have given up the settled farming life, Chengying does not intend to put down the farming technology completely. Slash and burn farming is also farming. It is always more efficient than grazing, fishing and hunting. Plant some crops with short growth cycle and high yield, such as sweet potato and potato. It can accumulate a large amount of food for migration during the short settlement process.


    While designing the film, the contractor inquired about the technical information on the PDA. The above information was very detailed. It even wrote clearly how to put nose rings on cattle and how to castrate livestock.


    This made him more and more believe that the PDA in his hand was the back hand left before he crossed over.


    "I caught the cattle! I observed the distribution of cattle of various sizes in the herd. I felt that it should be a kind of cattle with a very short growth cycle, but there was a problem..."


    When Chengying saw Liu Tianxin coming back, he blinked and asked, "what''s the problem?"


    "This kind of cow has two heads." Liu Tianxin''s expression is tangled, so he has already had the boundless world. He is prepared for all kinds of strange things, but he still feels very painful when he meets this strange guy.


    Chengying thought it was nothing: "what''s wrong with two heads? Since they can breed, I think there should be no fighting between the two heads. If they have two heads, they can eat grass twice as fast as ordinary cattle.


    Cows can produce more milk and calves can eat faster. Have you paid attention to cows before? "


    Liu Tianxin: "


    He always felt that the film was too grounded. He didn''t seem to be a strong man with extraordinary power. His calculations were no different from those of the old farmers in the field.


    But this kind of thing is simple to say, but Liu Tianxin can''t do it, just as he doesn''t have the patience to teach these primitive fools.


    "OK, if you don''t mind, I''ll get it back! Where are we going next?"


    Chengying sniffed: "to find other human tribes and annex them, our productivity is enough to feed more people. The natural resources of the flood and wasteland are extremely rich. It is not difficult to maintain the large tribe nomadism of 30000 or 50000 people by relying on the technology at this stage."


    "Can others swallow you? These primitive people are too lazy to lie down and never sit. Although hunting and gathering are dangerous, they work four or five hours a day, but they have to work from morning to night, and they don''t eat much better. I don''t think these primitive people will think about the future, let alone store much food for the future. Most of them won''t have anyone Willing to join you. "


    Chengying shook his head: "did I say I want to ask for their opinions? We need population. If the negotiations can''t get what we want, it''s war.


    For a long time to come, human weapons will only point to their own kind. This is very sad, but this is the price of rise. Only a unified country with strict laws can have the hope of breeding a bright civilization. "
