"Good! Well done! This thing is really useful!"

In the Qingque main tribe, Han Cheng, the tribe's son of God, happily stretched out his hand and patted Han Yousan's shoulder hard, not sparing his praise at all.

"Wait until tonight, and I will cook some food for you myself."

After Han Cheng finished praising these people, he said this to everyone with a smile.

Originally, Han Yousan and other members of the trading team were already very happy to see that the Son of God was so happy about the things they brought back. Now the Son of God said that he would cook for them himself in the evening. Han Yousan and other people were even happier, and their mouths were grinning from ear to ear.

Compared to other rewards, they hoped more for the reward of the Son of God cooking for them personally!

As the Qingque tribe continued to grow, the status of Han Cheng, the son of God of the Qingque tribe, also rose accordingly.

Moreover, the food cooked by the Son of God tastes especially good, and the Son of God basically doesn’t cook much now.

In today's circumstances, it is such an honor to be able to eat a meal prepared by the Son of God himself, specially for you!

Before, they saw that the rest of the people in the tribe were entertained by the Son of God who cooked for them personally because of their achievements. They ate in front of many people, and they were so envious!

Now, this thing that I have envied for so long is finally going to happen to me. How can I not feel happy and excited?

Han Cheng was happy to see Han Yousan and the others happy. He stood here and waited for a while. He asked Han Yousan and the others where they got the magnets from and how much salt they paid. He also looked at the other gains of the trade team. He personally took away the magnets that were tightly connected together without letting others interfere...

"Son, girl, look what this is!"

Han Cheng was holding some magnets in his hands and greeting the two children with a smile.

While greeting them, he raised his hand holding the magnet high, showing the two little ones what he was holding, looking very excited.

He looks like a child.

The two little guys came running over and kept looking at Han Cheng's hand.

I want to know what this black stone is.

He used his hands to pry the magnets apart, and then gave them to the two little ones respectively.

Of course, what Han Cheng gave them was only a very small part of what he took from the large piece of magnet.

The two little guys took the black stone from Han Cheng and seemed cautious at first because they were worried that the black stone would stain their hands like the carbon in the tribe.

Then they discovered that although the stone was also black, it would not dye at all.

This discovery made them feel more confident.

At the beginning, the two did not find anything special and did not think that there was anything magical about this black stone.

But they soon discovered something strange.

"Dad, look! They can stick together!"

Little Pea used his hand to pull off a small piece of the magnet, then put his hand next to a larger magnet and put them together. The small magnet was immediately sucked onto the larger magnet.

Such a discovery made the two little guys very excited.

Little Xing'er also learned to play like her brother, pulling off small pieces of magnets and putting them back together again, having a lot of fun.

However, Xiao Xing'er's hand strength is much smaller, so it is not easy to accomplish such a task.

Seeing the two children having so much fun, but still not finding any new ways to play after such a long time, Han Cheng, the son of God of the Qingque tribe, finally couldn't stand it anymore.

"Come, let daddy teach you something fun."

Han Cheng said this as he took the small magnet from Xiao Xing'er's hand. Then he put it on the ground and began to gently scratch it back and forth on the ground.

There is a thin layer of sand on the ground, which was pulled from the river and spread on the ground.

This is because when it is cloudy and rainy, the ground will become muddy when you walk here.

It is common knowledge for people in later generations that there is more iron sand in sand.

So Han Cheng took the small piece of magnet in his hand, and after rubbing it back and forth on the sand used for paving the ground for a while, he picked it up and saw that a lot of fine iron sand had stuck to the surrounding of the magnet.

There is no iron sand at the bottom of the magnet. This is because when Han Cheng was attracting the iron sand, the bottom of the magnet was rubbing against the ground, and the iron sand stuck on it would move closer to the surrounding area.

Looking at the extra iron sand around the magnet, Little Pea and Little Xing'er were particularly surprised.

It turns out that this stone called magnet can be used and played with in this way!

Little Pea immediately imitated Han Cheng, put the magnet in his hand to the ground and started scratching it.

Dad’s intelligence and the magic of the magnet do not end there.

Han Cheng returned the magnet to Xiao Xing'er, and watched the two little guys use the magnet to attract iron sand.

Alternatively, you can pull the iron sand off the magnet with your hands, throw it on the ground, and then bring the magnet closer to it to absorb it in mid-air.

The iron sand thrown on the ground was attracted by the suction of the magnet, broke through the gravity of the earth, and kept flying up and adsorbed on the magnet.

Later, the iron sand was adsorbed against the iron sand, or separated by the iron sand, and the bottom of the magnet looked like tofu with hair on it.

After playing like this for a while, Han Dashenzi, who stayed here, saw that the two little guys were playing non-stop but couldn't come up with any new tricks. As an old father who had played with these things a long time ago, Han Cheng finally couldn't stand it anymore.

"Come, Dad will teach you a new way to play."

Han Cheng said this.

Then Xiao Xing'er handed the magnet with a lot of iron sand in it to Han Cheng.

Han Cheng found a thin wooden board, then removed the iron sand on the magnet with his hands and put it on the thin wooden board.

After doing all this, hold the wooden board flat with one hand and use the other hand to hold the magnet and stick it to the bottom of the board.

As soon as the magnet was attached to the bottom of the wooden board, a lot of the loose iron sand on the board suddenly stood up, looking like a hedgehog.

Han Cheng began to move his hand holding the magnet slowly along the wooden board.

As he moved, the iron sand placed on the wooden board moved with him.

Seeing this magical scene, the two little guys' eyes immediately sparkled. They became more respectful to their father and felt that their father was simply an omnipotent being.

After giving a demonstration, Han Cheng handed the wooden board and magnet to Xiao Xing'er. After seeing the new way of playing, the two little ones immediately started playing here with great interest.

Han Cheng was so happy when he saw Han Yousan and others bringing back magnets after going out. Of course, it was not because the magnets could be used to entertain children and give them an extra toy.

It’s because in addition to letting children play, Han Cheng also knows some extremely important functions of magnets.

Of course, it is not used for audio equipment or anything like that.

This thing is too complicated and too engineering-intensive. Even if Han Dashenzi tried his best, he still couldn't make it.

What he was thinking about was something else that was extremely important, very practical, and did not require high technical skills.

This thing is none other than a compass!

Knowing the direction is extremely important, especially when walking in the wild!

The Green Bird Tribe is a tribe that often walks in the wild because they have caravans that are constantly extending outward.

Moreover, due to the times, at this time, except for the roads built by the Qingque tribe themselves, there were no proper roads in other places.

Most of them are primitive and wild.

Doing business under such circumstances, apart from other things, just remembering the way and identifying the direction will be a great test of the leader's ability.

There have been cases where caravans have fallen into danger because they lost their way for a moment.

It is precisely because of this that Han Cheng had thought of making a compass a long time ago to help people in the tribe identify directions when going out, reducing the probability of the tribe getting lost.

Last year, when the tribe started making sailboats, Han Cheng's desire to make a compass became stronger.

A compass is basically standard equipment for sailboats, especially those sailing out to sea, a compass is indispensable.

When sailing on the vast ocean, they need a compass to ensure the accuracy of their course more than trading teams traveling on land.

However, there has never been a magnet in the tribe. Even though Han Cheng knew how to make a compass, he was still in a situation where he could not do anything without the right ingredients. He could only worry and watch helplessly.

But now it’s different!

Now the trade team has brought back the necessary item, the magnet!

With a magnet, you can start making a compass. The structure is not complicated and not difficult, but its function and significance are extraordinary!

Thinking this in his heart, Han Cheng waited here for a while, then stood up and walked towards his house...

Not long after Han Cheng stood up and left, Wu came over holding his daughter.

When Little Pea, who was having fun playing with a magnet, saw him coming, he stopped what he was doing.

"Wu, Dad just brought this over. It's called a magnet. It's really fun!"

Little Pea said to the witch with great excitement.

“Look, you can play it this way, or you can play it this way.”

Little Pea enthusiastically demonstrated to Wu how to play with magnets that he had just learned.

Afterwards, he stuffed the magnet in his hand into the witch's empty hand, allowing the witch to play with this new and interesting thing.

When Xiao Xing'er, who was standing nearby, saw her brother's behavior, she followed her brother's example and gave her magnet to Wu to play with.

The two little guys are very close to Wu.

Because Wu likes children, and Little Wandou and Little Xing'er are the children of Han Cheng, the Son of God, and before Han Cheng built a new house, they lived in the same house. Wu likes to play with the two little guys when he has nothing to do. Under such circumstances, the two little guys are naturally familiar and close to Wu.

Wu was not polite. After taking the magnet, he squatted down, hugged his little daughter in one hand, and used the other hand to hold the magnet and play with the two little ones.

Wu was able to play well with the two little guys.

After playing like this for a while, Wu has roughly figured out the properties of this thing called magnet.

This thing is really rare and very fun to play with, especially to entertain the children in the tribe.

But are these really the only effects?

There was a look of doubt and thought in the witch's eyes.

He just received news that the trade team brought back rare things, and the Son of God attached great importance to it. He not only praised the members of the trade team repeatedly, but also rewarded them by cooking for them himself!

Based on my understanding of the Son of God over the years, this new thing called magnet must be very useful to be able to make him react like this. It should not be just for the children in the tribe to play with.

But if this thing is not really as simple as allowing the children in the tribe to play with it, then what is the purpose of it?

After all, I have experienced this thing myself, and it is indeed very suitable for children to play.

Wu held his daughter in his arms and fell into deep thought.

Wu would have understood all these things completely by simply asking Han Cheng, but he didn't do that.

This person who likes to use his brain likes to think on his own when he has nothing to do.

This is especially true when you encounter new things.

Standing here holding her little daughter and watching Little Wandou and Little Xing'er playing with iron sand, after thinking about it for a while, Wu's eyes suddenly lit up!

He thought of the important role of this magnet!

The important function of this is to absorb iron sand!

The usefulness of iron tools has been deeply rooted in people's minds. As a witch in the tribe, he knows better about the benefits of iron tools.

I remember that I once heard the Son of God say that there was a lot of iron sand in the river, which could be used to make iron tools. However, there were no suitable tools to separate and gather the iron sand in the river...

As soon as he thought of this, Wu suddenly became clear-headed.

He felt that he had seen through the truth of the matter. This feeling of being able to figure things out on his own without having to ask anyone else was really great!

It gives people an inexplicable sense of accomplishment.

Thinking this, he carried his little daughter towards the house where Han Cheng lived.

He had learned from the two little ones that the Son of God had returned to his house.

He went there now because he wanted to verify with the Son of God whether his previous thoughts were correct or not.

Although he was already sure that this was the case, he still couldn't help but want to verify it again.

People with knowledge are so particular about how they do things...
