Although there are no measuring tools now, through these tests, the unicycle can bear the weight of at least five people at a time. To put it into account, even if a person is 100 catties on average, the wheelbarrow can carry more than 500 catties.

And through the test, it seems that five people are still more than enough, and there is no problem with the last estimate.

The wheels of each unicycle are tailor-made, though, because it's too difficult to find wood of the exact same size.

And considering the problem of replacement later, the suitable piece of wood can only be used as an exclusive accessory for a car.

Many people think that inventing something is something that suddenly pops out of the head of some genius, but it is not.

The vast majority of scientific and technological inventions are due to the existence of such needs in society, and the satisfaction of such 'needs' can be rewarded, which prompts people to continuously improve and finally popularize.

Therefore, it is true that 'need is the mother of invention'~

After Chen Chao tried out the wind-powered wheelbarrow, it was almost time to make dinner. He gave the unicycle team an order to make another unicycle before dinner, and said that if there was a shortage of manpower, they could go to the pottery department and ask for a one-eyed tune.

It was also emphasized that Yi is very good at handling wood. If you are worried that the newcomer has little experience, you can go to the construction team and ask Yi to help.

And this time, the unicycle team was led by Qu. After explaining the task of the unicycle manufacturing team, Chen Chao went to see the work of the basewood team.

The little old man with the horns was thinking about pushing a few wheelbarrows, and Chen Chao was afraid that he would accidentally twist his waist when he was playing, so he took him to see the progress of the small stove.

When Chen Chao went to see it, he had already built twenty small stoves, which were basically simple small stoves with a few bricks. The size is too big to put the clay pot in, Chen Chao calculated, the number is almost the same, so let the stove team rest first.

Now these small stoves are used temporarily, and when the new residence is built, a room can be specially made as a canteen for making big pot rice.

When the time comes, it will be used as a canteen to eat, and inside it will be used as a kitchen to cook and cook. In the kitchen, there is a stove directly on the wall, which is neatly placed in a boxy and neat manner, which is refreshing to look at.

When the little old man saw these boxy houses, he didn't know what they were for, so now he was going to build a single room for rabbits?

But he was not interested in this matter at all in his heart, only ~

Lao Tzu wants to push a wheelbarrow!!

Chen Chao looked at the little old man's body over there, his heart on the wheelbarrow side, it seems that this person didn't remember who had mentioned the need for fire trouble several times before, and now he solved the problem, good guy, this thing doesn't care about this at all.

It seems that I can't forget the thing I didn't push on the wheelbarrow just now~

But there is no way, the little old man's small body, who dares to let him push 500 pounds around?

What should I do if I accidentally twist my waist?

This old arm and leg is old, and he doesn't care about his body at all.

Even though the little old man was thinking that he was going to push the wheelbarrow, it was time to prepare dinner. He had no choice but to call his old henchmen to get ready to work.

After a while, the old followers also came to the edge of the river one after another, washing pots and pots, smashing ice, and baskets of fish, all preparing to start making today's dinner.

Taking advantage of the fact that there was still some time before dinner, Chen Chao asked Yuan and the little old man to put down the work in their hands, and everyone went into the house to have a small meeting together.

The main content of the meeting was about going to other tribes to trade people after a while.

Chen Chao first said his thoughts, specifically that when the time comes, he will bring a batch of pottery, straw sandals and rattan baskets to the nearby tribe to replace a group of people and come back, planning to bring five or six people.

The little old man with the horns on his back became energetic as soon as he heard about it, and Chen Chao, who was playing with that strange thing before, mentioned it to him. He agreed, but on one condition, that he would also go.

Yuan agrees that the tribe can absorb more people, but he raises a practical question. That's where this group of people comes, what do they eat? Will there be enough food for the tribe by then?

Although there are now fourteen more people in the tribe, there is no pressure at the moment. If there were fourteen more people, it would be a lot of pressure.

Chen Chao thought about it and first vetoed the little old man's request to follow, which was also supported by Yuan. He also knew that the age of the witches in his tribe was really not young, and he was no longer suitable for long journeys.

Last time, he rashly ran down the mountain to greet everyone, but Chen Chao and Yuan were startled, this little old man didn't bring anyone with him, and he was not afraid of being eaten by fierce beasts.

Then in response to the second problem of not enough food raised by Yuan, Chen Chao thought about it in his heart, this is a troublesome problem, but it is also a problem that must be solved.

There is no problem with the fish resources in the small river supplying the current Tian Yuan tribe, but after a hundred people, it may be a little stretched. The main thing is that there is no other food in the tribe that can be eaten alternately now.

The type of food stored in the previous store alone was too simple, with only a few kinds of animal meat, chestnuts and fish. It's okay to eat like this in the short term, but it's going to be a problem to eat like this in the long term. Many people do not get a good supply of vitamins that the body needs, and even vegetables and fruits are not eaten now.

The problem of meat is still relatively easy to solve, but when the time comes, there are too many people brought back, and there is not enough food in the tribe?

Well...

Aren't those lynx arrogant? He also attacked the candidate members of my Tian Yuan tribe.

You wait, I, the deputy leader of the Tianyuan tribe, Chen Chao, will never let you see the spring sun again~~

After thinking about it for a while, Chen Chao also gave an answer to the second question, mainly the lynx group in the mountain and some large beasts under the mountain.

"Remember when the Grass Tribe came and was attacked by a group of lynxes? In the next few days, the hunting party can consider a trip to kill a batch of lynxes first, and then there will be a large surplus of fur and meat.

And after that, we can hunt under the mountain, last time I saw it, the beast resources under the mountain are still relatively rich. ”

After such a long period of study, Yuan and the little old man have been able to barely understand some longer sentences, but it will take a long time to process and analyze, the key words and specific meanings in the sentences.

This time, they all coincidentally captured a key piece of information, that is, 'hunting under the mountain'?

The questions raised by Yuan and the little old man were all about whether a new place of residence at the foot of the mountain was about to be established.

Chen Chao smiled and nodded, affirming their thoughts, and then continued, "Yes, we are going to start building a new place to live." ”

When the two of them heard the news, they couldn't help but be overjoyed. Yuan was still sitting calmly on the kang, and the little old man had already jumped to the ground for a long time.

After the excitement of the two of them passed, Chen Chao continued, "The main reason why we haven't directly built a new residence before is that the distance between the new residence and the Tianyuan tribe is too long, and it will be very tiring to go back and forth in a day.

But if you don't come back, you're likely to be attacked by wild beasts at night. ”

Yuan and the little old man both nodded, agreeing with this statement very much, and they were also very curious, how would the deputy leader of their tribe solve this problem?

Chen Chao didn't answer this question directly, but went around to another topic and asked what he thought of the house he had built recently.

Although they were puzzled, they both replied, "Very good, very beautiful." ”

"Can you resist the beast's attack?" Chen Chao asked again.

The little old man nodded with Yuan and shook his head again.

The little old man with the horns of the sheep was the first to speak, "It's okay in general, but it's not okay in the big way." Last time... See... Oversized... Eat the leaves..."

Although there is nothing wrong with listening to others, when it comes to expressing themselves, Yuan and the little old man are still a little stretched.

Chen Chao thought for a while, what the little old man meant should be that it was okay to resist ordinary small and medium-sized beasts, but not large ones. And the little old man should have seen the giant rhinoceros eating leaves last time.
