Humans are great because they have learned to free their hands so that they can use tools.

Luo Yang thought so.

There is no provision on how to count sand in the customs clearance conditions, that is, it is possible to use tools.

He first pulled out a half-fist-thick sapling from the soil and set it aside.

Then he took a flat stone from the woods and sharpened the thinner side of it into a fairly sharp blade on the others.

Holding a freshly baked stone knife, he made a small opening in the root of the sapling, and then tore it hard.

The bark was violently dismantled, and the sapling in his hand turned into a slippery wooden stick.

After breaking off his arm, he took the bark of the tree and tied the stone knife to the top.

A stone axe that can be seen can be seen successfully produced.

With the stone axe, Luo Yang's work progress was accelerated again, and stone hammers and stone cones were made one after another.

For him, who had to support himself when he was a child, and even had to take care of his father, it was easy to do these things.

When the preparations were complete, he set his sights on the mature fruit trees.

Over time, as trees are broken down into their components, the prototype of an object is about to emerge.

That is, the pole scale.

That's right, that's what Luo Yang came up with.

Since the size of each grain of gold sand is the same and the amount is not light, the weight of a random pile can be quickly weighed by using a rod scale, so as to get the total.

Of course, the most important thing is that he is too familiar with this thing, and he calls it pork every day...

Space wall, with its own light source.

And Luo Yang, who has been busy for so long, doesn't feel sleepy at all.

Therefore, he could only rely on his intuition and felt about half a day.

The pole is finally done.

Looking at his painstaking masterpiece, Luo Yang nodded with satisfaction.

The stem is a thick trunk without bark, which is hung from the middle by the bark on the fork of the tree.

The weighing plate is a large basket made of hundreds of soft branches, which is also fixed at the top of the weighing pole by the bark.

And the last scale, that's a big rock...

Overall, it's not pretty, and it can even be described as very rudimentary.

But in Luo Yang's eyes, what truly reflects human wisdom is the role and creativity.

Shape or something, there's a fart.

Just like he Luo Yang is so handsome, is he not trampled to death by those jealous pigs?

"A bunch of ungrateful guys!" Luo Yang scolded to himself.

......

After solving the cheat tool, Luo Yang swung his axe again and chopped down the tree.

He's going to make a car.

The gold sand is not in the forest, so you can't take it with your hands, right?

In another half a day, a unique wooden wheel unicycle was born.

Subsequently, he deliberately made a hard hat out of leaves, so he made a full set.

Whistling all the way, he pushed the cart and transformed into a happy cuckold man, and the sand transportation officially began.

The first trip was successfully returned, and Luo Yang proved with his strength that the wheelbarrow was indeed usable.

Of course, it just works.

Wiping the sweat from his head, he didn't rush to carry the next cart, but poured all the gold sand into the weighing plate hanging in the air.

There was no movement.

It seems that the position of the stone is too far back.

Luo Yang climbed up the fruit tree and pushed the bark that was dragging the weighed stone into the middle.

Yes, it's kind of a way to float up, go on.

Ha, get up.

This time, the two ends of the weighing rod swayed slowly to show a kind of balance.

But it's unstable.

This kind of error of relying on vision to measure as little as a grain of gold sand is still quite unreliable, right?

Luo Yang grabbed his hair, looked at the undulating weighing rod, and suddenly had an idea.

He jumped off the tree, quickly made a stick, and then picked up the stone hammer and cone and climbed back up the tree.

I looked at the weighing rod, it was not bad, and it was basically in a parallel state.

So the stick is pressed against the trunk of the tree, and the other end is carefully attached to the weighing rod in the opposite direction of the weighing plate.

Noting the position of the stick on the trunk of the tree, Luo Yang picked up the stone hammer and knocked it on the stone cone, opening a hole in that position.

The stick was stuffed hard, and the perfect stopper was ready.

In this way, as long as you put more sand next time, the weighing rod will be blocked by the stopper.

Take it out little more.

Soon, you'll get the same amount of gold sand as you did on the first trip.

ps: I got up at 4 o'clock this morning to catch a flight, plus I wrote yesterday until the early hours of this morning.

So Yishan has a bad headache, and he is still very busy with work today, resulting in the number of updates so far, only these.

But I'm still writing!

In order to keep changing, I can only send these first...
