Cattle are the most primitive power that human beings have learned to use in a long time, ox carts, the amount of transportation is not less, at least, in childhood, he Han Wenzheng drove the ox cart, an ox cart can transport about 1,000 kilograms of things, if you can tame some cattle to help, and then make an ox cart, in this way, the volume of transportation will naturally increase, it seems that he Han Wenzheng also has a day to be a cow tamer.

In this uninhabited land, there are wild weeds everywhere, it can be said that it is not an exaggeration to describe it as a grassland, there are cows and horses on the grassland, the most primitive power, cattle are better than horses, Han Wenzheng left Yanhuang City to find cattle.

Only two kilometers east of the city, I saw a large herd of cattle, the number is enough three hundred, too many, if you catch one by one, then I don't know when Lu Dao will be caught, Han Wenzheng's idea is to find a cow, as long as the cow is subdued.

After half an hour of observation, Han Wenzheng finally found a cow, it was a very strong bull, good guy, this cow weighed two thousand catties, very strong, it was really a good cow, and if you wanted to use it to pull the cart, you could also pull more wood.

Han Wenzheng burst into the herd empty-handed, and faced the cow, before the cow didn't understand what was going on, Han Wenzheng's hands had already grabbed its horns, and with a strong hand, it had already fallen to the ground, just kidding, Han Wenzheng now has the strength of 10,000 catties with both hands, and the board is overturned to the cow, which is a small meaning.

Han Wenzheng let go of his hand, and the cow stood up, neighing and snorting in his mouth, obviously very unconvinced, thinking that it was the strongest cow in the herd, and now it actually made people fall down, it was really a loss of face for the cow, no, it had to be recovered, so as soon as it stood up, it rushed towards Han Wenzheng.

It's easy to do, Han Wenzheng stretched out his hands, grabbed the horns again, and easily fell the head of the cow to the ground with a fight. Let go again, the head cow stands up, and comes again. The other cows neighed and were ready to come up to help the cow, but the first cow made a cry in its mouth, preventing the other cows from rushing up, and then, with all its hooves, rushed towards Han Wenzheng, and it wanted to fight Han Wenzheng alone.

Han Wenzheng grabbed the horns of the cow again, this time he didn't fall down, but only withstood the impact of the cow, the cow used force many times, but the guy on the other side who didn't look like a cow was like a mountain, he didn't even move at all, it couldn't make the other party move at all, which made it frustrated, and its four hooves kept exerting force, kicking the ground to the dust, but it was obvious that it was just a waste of strength and in vain.

Han Wenzheng smiled: "Are you still not convinced?" and then pushed the head cow board to the ground. The cow was served, and the guy in front of him who was not like a cow could not be dealt with by himself, and he had to accept it if he couldn't beat it, which was the nature of the animal world, so it obeyed.

After subduing the cow, Han Wenzheng selected twenty of the strongest cattle from the herd, and he couldn't domesticate them any more, it could only be a waste, and it would take him a long time to tame these twenty cows.

Han Wen just can't tame beasts, but he can train soldiers, although the two are different, but the principle is the same, the cow is not convinced, the horns will put it down, and then punch it a few times, until it is served, ask you are afraid? At night, I will mow the grass and feed the cattle, and take the cattle as companions, so if I can't tame it, there is no way. In fact, cattle are the same as horses, they are very spiritual animals, and they are easy to domesticate, but you should also be careful, cows also have tempers, otherwise, how can you call people with bad tempers as cow tempers?

Make a few softer vines to make a bull's nose circle, wear the cow's nose, and then tie the vines, so that the cow will not have any cow temper to play, and the days are long, and they will be very obedient and obedient, so that they will go east to the east, and west to the west, which finally has some effect.

In this period of cattle taming, of course, Han Wenzheng will not be all cattle taming, and has done a lot of work, for example, chopping trees, waiting for the sun to dry the trees, so that it is easier to move, and there is also to find wood to make ox carts, Xuanyuan Jian is also a little pitiful, with this new master, he has not yet become famous, but he first became the axe of cutting trees, and it is a bit embarrassing to say that he is gone.

It is not easy to make an ox cart, the most difficult thing to do is the wheel, use fire to bake the wood soft, and then bend the wood and fix it for a period of time, so that it is made into a curved arc-shaped half wheel, and then put together several such half wheels to become a round wheel, but it is difficult to achieve the same size of each wheel, although it is a little difficult, but it is still difficult to defeat Han Wenzheng.

In fact, it is not difficult to use the carriage, there are no iron nails at the joints, it is not important, you can use this nail, the same sturdy, there is no special machinery, it is not important, some are brute force, it is better to use a fist than a hammer, use the Xuanyuan sword to cut the big tree into a piece of wood, and then spread it on the carriage to become a very good carriage.

In short, after more than a month of work, the ox cart has almost been made, the ox has been tamed, and the ox can be trained to pull the cart, first of all, the head cow is trained to make Han Wenzheng so scared, Han Wenzheng can only do what it asks it to do, and it does not dare to disobey at all, pull the cart? Although it does not know what the road is doing, it cannot resist.

Put on the wheel, put on the nose, tie the reins, put on the car, the head cow is obedient and close, Han Wen is letting it go, it goes, it doesn't seem to be a difficult thing, it's okay, it's easy. After having a cow as an example, other cattle also put on the cart one by one, and the epoch-making tool of the ox cart appeared in the Yanhuang clan and officially appeared on the stage of history.

Black, it's really dark enough, the burning value of a kilogram of dry wood is 12 million joules, and the energy of one kilowatt-hour of electricity is 3.6 million joules, according to the law of conservation of energy, a kilogram of dry wood should be worth 3.3 kilowatt-hours of electricity, but after a kilogram of dry wood is poured into the energy pool, the energy displayed is only 1.5 kilowatt-hours of electricity, and there is 1.8 kilowatt-hours of electricity to swallow the energy pool in vain. It's really so dark that it can't be darker anymore, but there is no way to be black, the meat is on the felt board, so you can only let it go.

Han Wenzheng is cutting wood at night, and there is to feed the cattle, pacify the cattle, during the day to drive the ox cart to transport wood, he himself drove an ox cart, other cattle will follow, no need to waste thought, this saves him a lot of time, each ox cart is just to pull a thousand kilograms of wood, a twenty carts, that is, 20,000 kilograms of wood, can only exchange 30,000 kilowatt-hours of electricity, to make up enough energy of ten crystals, to transport 33,334 times, he Han Wenzheng alone has to load the car, and unload the car, at the end of the day, hurry up slowly, but only ten times, if the weather is bad, can not work, then it takes more time, even ten times a dayIt will take him at least ten years to gather ten crystals of energy, my God! Ten years for one person, what about a hundred people? a thousand years? Don't live.

In this environment, Han Wenzheng has no other better way, of course, if there is oil or coal, of course, it is much better than wood, but to find it, he Han Wenzheng has not learned the ability of prospecting, and he is not an expert in prospecting, so naturally he does not have the ability to find coal and oil deep underground. He believes that this planet should also have open-pit coal mines or oil mines, but this thing is not something you want to have, you have to meet it, and if you want to meet an open-pit coal mine or oil mine, it can only be met but not sought.

It's just that the wood has been transported for a few days, and Han Wenzheng knows that it is not a way to go on like this, it is definitely not a way, if it really takes three hundred years to be able to produce 100 people, (producing people can also help, so the time should be less), before he can be promoted to the first level, can he afford this time? Don't forget, the treaty signed between the Yanhuang clan and the Wufu clan is only 100,000 years, and he Han Wenzheng will not think that upgrading to the first level is the most difficult, and the future upgrade will definitely be much more difficult than now, if it really takes three hundred years, he will definitely go crazy, crazy because of despair.

In fact, energy is everywhere, such as the big river named Nianxiang River, there is more energy in the river, but he has no way to use it, the generation of water energy is the potential energy of water under the action of gravity, Yanhuangcheng is twenty meters higher than Nianxiang River, he Han Wenzheng can not raise the water twenty meters and then pour it into the big mouth of the energy pool, there are all kinds of machinery in history He has thought about it all, cylinder car, overturn, Siphon and so on, it doesn't work, no matter how much he thinks about it, and he calculates repeatedly, it still doesn't work, Han Wenzheng has no plan for a while, he can't be asked to make a barrel to carry water.

Sometimes, Han Wen was thinking: It would be good if there was a cultivation level 10 or above, and he could use the method of moving mountains and reclaiming the sea to move the wood to the energy pool, so that there would be no such trouble as transporting it. It's just that he has a tenth-level cultivation? So, he can only think about it.

Han Wenzheng understands that his biggest problem now is not only the problem of energy, but also his own problem, on this planet, for the time being, he is alone, without any friends and companions, lonely, Loneliness, this is his most terrible enemy, even if his will is firm, after a long time, his psychology will definitely have problems, no one's will can always be kept at the best level, even if it is a god, people, in the end, are still social animals, if it is not for the autumn water sometimes said two words, he will wonder if he will not even be able to speak after a few years.

Han Wenzheng mechanically chops wood every day, cuts the wood, and then drives the car, but in his brain, he has never given up if he uses a better way to get more energy, but no matter how much he thinks, he can't find a better way, he suddenly found that his level is still too far behind, and there is no way to solve even this little thing, which is really incompetent.

At sunset, he saw that the mountains in the distance were full of wood that he had cut down, all of which had been dried, but he had no power to move back, so he could only watch, he really wanted to laugh and cry without tears, Han Wenzheng sighed: "If only the wood could walk on its own, I wouldn't have to work so hard." ”

He sighed to himself, and suddenly, he slammed his fist on the head: "Stupid, I'm a pig, I'm really stupider than a pig, is there anyone in the universe who is more stupid than me?"

(Repeatedly, it can only be a change from tomorrow, and it can't be written so fast!)
