After handing over the things to Wu, Wang Tian no longer paid attention to the expressions of the three of them. With your toes you can imagine, they will eventually be placed on the altar tonight.

Picking up one of the wood-fired firearms, he turned and walked out of the cave, heading in the direction of the factory.

The four kilns seem to be taken by everyone taking turns to take care of them, and everyone is taking a break from adding firewood to the fire, and everyone is working at full strength.

Wang Tian looked at the sun overhead, it was not yet noon, and more than 200 bricks had been made in the field in front of the factory, and at this rate, 500 pieces a day were appropriate.

The second brother of King Kong has already cut the thatch and spread the roof of the factory. There are some stone slabs, bamboo poles and other heavy objects pressed on it, which can protect against the wind. Otherwise, a strong wind blows, and the thatch is gone.

Yesterday, the completion of the factory let the tribe see the benefits of building a house, and they were full of enthusiasm for their work.

He rebuilt a stove where he had smelted his axe. Then make a number of large and small scales. Each one differs in weight.

The appearance of the scales is naturally the same as that of the aftermath, and a total of fifteen have been made. After it is done, put it in the stove, turn the firearm by hand to ignite the fire, add firewood to burn it, find a stone slab, cover it on the stove, and pull the blower to accelerate the firing.

Wang Tian doesn't care whether it can become pottery or not, he only needs to burn the internal water vapor and harden it.

When Heizi saw Wang Tian coming, he was tinkering with something again, and he followed him.

When I came over, I was dumbfounded, a boxy lump, big at the bottom and small at the top, and a hole. What is this for?

"You know how heavy you are?" Wang Tian asked.

Kuroko shook his head blankly.

So Wang Tian entered the popular science mode again.

He pointed to a dung basket and said, "Which is heavier, a dung basket of rocks or a dung basket of earth?" ”

Kuroko pointed to the stone.

"If the answer is correct, add 10 points."

Wang Tian gave a thumbs up.

"Then a bowl of fruit or a bowl of meat, which is more satisfying"

This time, Kuroko didn't have to think about it, and directly chose meat

"Add 10 points to the correct answer"

"What about three bowls of fruit and one bowl of meat?"

Wang Tian asked again.

Kuroko thought about it for a while this time, but still chose meat.

Wang Tian scolded with a smile: "You foodie!" I mean, which is better to hold your stomach. ”

Nima, this is talking to foodies about food, then you can't have a pleasant chat!

Kuroko may be afraid of being beaten by Wang Tian, the fruit of this obedient choice.

"Do you know why?"

Kuroko shook her head...

"A piece of dung stone and a piece of dirt seem to be the same amount, but the stone block is heavier."

Wang Tian strengthened the word "heavy" and continued: "And the same bowl of fruit and a bowl of meat, the meat should be heavier, so the meat is fuller. ”

Wang Tian stopped talking, leaving time for Kuroko to think.

Kuroko still understands this truth, and it is not the same weight to pick up a piece of wood of the same size as a stone.

Wang Tian looked at the sunspot with a sudden look on his face and continued: "Three bowls of fruit and one bowl of meat, excluding the characteristics of foodies, everyone will choose fruits!" ”

The last half of the sentence Wang Tian was shouted out.

Kuroko scratched her head embarrassedly. A hearty smile.

In fact, Wang Tian wanted to compare two bowls of fruit with one bowl of meat at first, and it seems that he still underestimated the essence of foodies.

"A bowl of fruit and a bowl of meat seem like so much, but the meat is heavier and more resistant to hunger; Three bowls of fruit are much heavier than one bowl of meat, and even if the meat is more hunger-resistant, it can't be compared, understand? ”

Kuroko thought about it and nodded as if he didn't understand.

Wang Tian picked up a long stone and put it on a log to keep it balanced.

"Both ends weigh the same," the hand drew a horizontal line in the air.

Pick up a stone and put it on one end of the scale, and the end where the stone is placed immediately sinks.

Then he made a lump of mud the same size as the stone with his hand and placed it at the other end.

"It's still heavy on stone."

The hand drew a diagonal line in the air pointing to the stone.

I picked up another lump of mud and put it on it.

"Still heavy stone"

The gesture party appeared. It wasn't until he put on the third lump of mud that the scales moved.

Wang Tian finally put a small half of the mud ball, and the balance returned to level.

Again leave Kuroko time to think.

After a while, Wang Tian placed the stone and the three clay balls on either side, and used a stick to draw an equal sign in the middle.

"One stone is equal to three and a half pieces of mud." Wang Tian made a summary of popular science.

The book is the same text, the car is the same track, and the weights and measures are unified. Wang Tian seized every opportunity to instill his ideas in everyone in the tribe.

And with the invention of more and more things, eating, bowls, fish, pottery, metal, axes, bricks, walls, houses, ...... Wait a minute.

The invention of these new nouns, he had heard more and more frequently in the conversations of the tribesmen.

This is the same reason that after the Japanese devil invented karaoke, the whole world called it so.

In fact, the spoken language of primitive people is very limited, in ordinary communication. They're actually saying word by word.

Therefore, there is no problem with the receptivity of the tribesmen.

In the Song Dynasty, if he traveled to the Celestial Dynasty in the later generations and scolded people, he would become a star master in the seven-grade sesame official in minutes.

In addition to thinking about that, keeping warm also produces chatter. The ancients cherished ink like gold, and the literary language was in three words, saying all the things in the world, and portraying them into three points.

As for modern people, look at what the author wrote, the author is just across the screen, not afraid of the majority of readers throwing eggs at me. Otherwise, I wouldn't have dared to lick my face and publish it.

Uh-huh, what's that, it's a bit off-topic, and if you have a recommendation ticket, please smash two of them.

Kuroko's gaze swept between the two piles of things, and he picked up the simple scale and fiddled with it. After a moment, he suddenly appeared.

"I'm going to make something called weighing, so that we know how much food we have, how much it weighs, how many people can eat."

It was almost noon, and at this time, the second brother of King Kong had already dragged the wood cut in the morning to the factory.

"Son of Heaven," the second brother called, pulled up Wang Tian, and came to the side of the stone foundation of the factory, and then the leader also came over to greet the second brother.

Wang Tian knew what he meant, and a pile of small broken stones was piled up with lime mortar and became a whole. Yesterday, when he covered the roof of the factory with soil, it was still shaking, but today the second brother has been stable when he laid the roof with thatch.

The second brother seems to be rude, but he is actually careful, and he found the problem. He and the leader finally understood that even if they stacked these bricks together to form a wall, they could kick them down with a single kick. And the reason why the Son of Heaven still insisted on building.

In fact, such a small stone foundation, with the courage of the second brother of Jingang, can still overturn it with one foot. Lime mortar is still not comparable with cement.

But it is no problem to build a wall dozens of meters long and three or four meters high.

Because of the weight of the wall, and the staggered wall building method, the load-bearing of the entire wall becomes a whole. Once this weight is joined by lime mortar, it is beyond the reach of humans and ordinary beasts. Not to mention that the thickness of the walls will reach a terrifying 70 centimeters.
