Under the expectation of everyone, the time came to the penultimate day of the group, and the kang head in the room was ready to sleep after yesterday's baking, and everyone in the tribe had eaten breakfast. Grabbed weapons and tools and walked out of the tribe gates to start the day's work.

There were 5 women who were arranged by Xiaoli to cut thatch near the river and use it to lay the kang, and seeing that everyone was very cooperative with Xiaoli, Wang Tian also let go of the doubts in his heart.

Wang Tian actually hid aside, quietly observed, and finally determined that the five people who were arranged to harvest the thatch did not have any resistance, everyone as usual, after receiving the work task, picked up the weapon and the special harvesting tool made _ stone sickle, put on gloves and set off directly, Wang Tian hurriedly came out and let them take the little Fu horse and put on the carriage and set off.

This is a good thing about primitive society, everyone doesn't have too much utilitarianism, in this real society in later generations, Wang Tian estimates that it will be difficult, and the game of two people can fight to the death, let alone a tribe.

Human beings in primitive times lived purely, without so many intrigues, deceitful and deceitful, even if they lived poorly, everyone was happy.

Everyone didn't push back her work arrangement because Xiaoli was a hairy little girl who had just become an adult, and if it was placed in the next generation, it would be all kinds of palace fights.

Including Wang Tian, everyone lives very happily, although the material conditions are poor, but life is not just happy, less comparison, more pragmatic, the primitive era of people's pursuit and yearning for a better life, firm Wang Tian led everyone all the way to the faith.

Huzi is also involved in cultivating the land today, and several leaders have their own affairs, and the second brother of King Kong led several people from the logging team into the jungle today to find suitable materials for making Quyuan plows.

After a period of time, he will also assist Liu Bei and Dashou to make various agricultural tools, Wang Tian wants to lead the tribe into the agricultural civilization, the production of tools is very important, tools are productivity, in the case of the total existing population has not increased, Wang Tian can only improve the existing productivity level of the tribe through this method.

And the leader will also accompany Wang Tian into the grassland again after the tribe has entered, and the grassland has two large animals that are vital to the tribe.

Wild horses can improve the tribe's mobility and expand the tribe's living space, and places that were previously inaccessible will become the tribe's backyard after owning horses.

Everything that a horse can travel to and from in a day's range, including food, flora and fauna, various minerals, spices, and important human resources, can be continuously transported to the tribe.

For example, if you can have horses on the grassland this time, you can return from day to night, and Wu can also rest assured, so that you will not be worried and worry about everyone's safety.

In China's agricultural civilization for more than 2,000 years, as the most important animal power, the cattle occupy an important position on the historical stage.

For a tribe that wants to enter the agricultural civilization, the importance of ploughing cattle is far higher than the demand for war horses, and it is imperative to explore the grassland again.

The work of cultivating land, after the two leaders left, Wang Tian did not plan to stop, as the so-called snake without a head is not good, although everyone is working diligently, but there is a leader in it, everyone's work will become more targeted, know where to go.

This requires Huzi to lead everyone to do it together, Wang Tian found that he can endure hardships and use his brain, which is enough, he can endure hardships and be able to persevere, persistence is victory, and he can use his brain, he can innovate, and innovation determines the future.

The simplicity of the primitive people, the intelligence of Huzi and Xiaoli, Wang Tian believed that they could rest assured that they would hand over these two pieces, and he himself continued to tinker with the plow.

At this moment, the big hand came to Wang Tian with three handmade ploughs, the wooden accessories of these three handmade ploughs, and the drilling holes had been made yesterday, and through the polishing of last night and this morning, the bones were finally polished successfully.

Wang Tian picked it up and looked at it, and there were two that were completely fine, but the third one was completely inappropriate.

The reason for the inappropriateness is that the "hanger hook" is too far away from the bone, so that when in use, although the bone-hanger can be stepped into the ground smoothly, but when turning the land, because the hanger hook is too far away from the bone, a little pry the wooden handle, the clothes frame has already touched the ground.

This results in the fulcrum in the principle of leverage, which is not in the right position and cannot play a role in saving effort.

Wang Tian told Dashou this principle, and explained the principle of leverage to him through the model, so that he could understand what went wrong, and it was better to teach people to fish than to teach them to fish.

Helping these people in charge to solve a problem can not play a substantive role, the important thing is to teach them how to solve the problem.

Through the field experiment of the Tianzi model, Dashou understood the importance of the position of the fulcrum in the lever principle to save effort.

Although he didn't understand the reason, he already knew the method, and through his own thinking, he could solve the same problem by himself.

After that, Wang Tian asked him if he had suitable wood, if not, just remove the two hooks, the presence or absence of the secondary stepping on the hand plough did not have much impact, and asked him to send it to the cultivated land group quickly.

The big hand put down the manual plough that needed to be reworked, and walked towards the cultivated land area with the other two, the matter has priorities, and the two that have been made must be sent to the cultivated land group immediately, and the one that is not qualified, and after the change, he will run one more trip.

……

In addition to the curved plough, the most important thing is the plough shovel, Wang Tian found two bones like a back triangular shovel in the bone pile, and I don't know which animal's shoulder blades.

The appearance of the bones is triangular, the maximum width is between 15~20 cm, and the shape is just right for making a plowshare, and he walked out of the cave with these two shoulder blades.

At this time, the five divine dog soldiers were making noise at the mouth of the cave, and when they saw Wang Tian take out two bones, they thought it was time to eat, so they jumped up and pounced, scurrying at Wang Tian's feet, blocking Wang Tian from being able to walk.

Wang Tian had to make a sound to drive him away, and at this moment, the two little tiger cubs who had just finished seeing the nurse fluttered and joined the battle group.

It's still the same old routine, one left and one right hugged Wang Tian's feet and neck, and Wang Tian was completely speechless. "While playing, my brother is very busy."

Helplessly, the big tiger and the little tiger just didn't let go, Wang Tian had to drag the two wool shoes, moving unhurriedly, this is not beating, scolding is useless, just when Wang Tian was helpless, he heard a burst of laughter like silver bells.

"Big Tiger and Little Tiger, you two will be spoiled when you are full!" After speaking, Ling'er threw out a dried fish that had been prepared a long time ago, and threw down the five divine dog soldiers who were jumping up and down.

The five little wolves frolicked with each other and ran away, so Wang Tian let out a long breath, and at this time Ling'er came over and picked up the two tiger cubs.

The wolf cub can be weaned in 5 weeks, but the baby tiger needs 5 months, which is fortunate because the human lactation period can be as long as a year, otherwise the baby tiger will have to starve to death.

When the five little wolves first arrived in the tribe, they had not yet opened their eyes, and the time of birth was estimated to be two or three days earlier than the two little tiger cubs, and after a few days of hunger, they actually began to eat meat soup.

After drinking the milk, in a little more than a month, the five wolf cubs have fully grown and their fur is getting brighter and brighter, and they are now completely weaned.

But the two little milk tigers are still in the form of babies, and every day after eating and drinking, they will come to Wang Tian to play for a while, and they are basically sleeping at other times.

This gave Wang Tian the possibility of acting independently, otherwise there were two hairballs hanging on his legs, and he wouldn't do anything, so he put them on the stool, stroked their fur with his hands, and the two little guys were so comfortable that they fell asleep quickly.

At this time, the second brother of King Kong had returned to the tribe and brought back a bundle of all kinds of curved wood, from which Wang Tian selected the best two to make ploughshares, these two pieces of wood were simply natural curved wheels.

It only needs to be bent on the beginning and end of the wood with fire, and it can be used directly, and the size is just right.

Wang Tian asked the second brother to peel off the bark of the tree, and began to light the fire, ready to play on the fire, and then bend the ends into the desired shape.
