I am a primitive

This important function is to absorb iron sand!

The usefulness of iron tools has been deeply rooted in the hearts of the people. As a witch in the tribe, he has a clearer mind about how iron tools are.

I remember that in the past, I heard the son of God say that there is a lot of iron sand in the river, and the iron sand can be used to make iron tools, but there is no suitable tool to separate and gather the iron sand in the river...

As soon as he thought of this, Wu suddenly became enlightened.

He felt that he had already seen through the truth of the matter. This feeling of being able to figure things out just by himself without asking others is really very good!

It gives people an inexplicable sense of accomplishment.

Thinking this way, he hugged his little daughter and headed towards the house where Han Cheng lived.

From the mouths of the two little guys, he already learned that the son of God returned to his house.

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

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

A learned person is so particular about doing things...

-------------Chapter Dividing Line---------------

"... Son of God, this magnet is really a good thing!

Get some more, absorb the iron sand, and then use the iron sand to make ironware. Our main tribe can also produce some ironware by ourselves, so we don’t have to always transport it here from the Tieshan residential area. "

In the eastmost room of Han Cheng's house, Wu, who came here with his daughter in his arms, said to Han Cheng with a smile, constantly praising the usefulness of the magnet, and wishing that the magnet would be used in the future. The role of tribes is envisioned.

After finishing these words, Wu looked at Han Cheng expectantly, wanting to see some emotions on Han Cheng's face, such as "Wu is so powerful, I haven't said it yet, you have already figured it out" and other emotions Come.

However, Han Cheng, who had found some tools and was about to do something, was stunned for a moment after hearing Wu's words.

Han Cheng didn't think about the matter of magnets absorbing iron sand, and then letting people use iron sand to make iron objects.

If this lodestone appeared earlier, iron ore and copper ore were far from being found in the tribe, and they were smelted with the two, then the lodestone appeared in the tribe, then of course the first thing I thought of was not to use lodestone to make a compass, but to make a compass like a witch. As said, use a magnet to absorb iron sand, and then use iron sand to forge some iron objects.

But now, there are copper mines and iron mines in the tribe, and they have been able to produce serious ironware through smelting.

Under such circumstances, it seems a bit redundant to use magnets to attract iron sand, and then use iron sand to make ironware.

Or it's not worth it.

Because it takes a lot of iron sand to make ironware.

Sometimes it looks like a huge pile, but actually using it to make ironware, not many can be made.

Compared with smelting with iron ore, it is too far behind.

Moreover, the acquisition of iron sand is also very troublesome, requiring people to constantly turn the sand, which is very hard and troublesome.

When Han Cheng was a later life, he saw people sucking iron sand in the river.

The flat riverbed is full of sand piles and deep pits...

Under such circumstances, he is naturally not interested in letting people absorb iron sand and then use iron sand to make ironware.

Wu Ben is a wise person. Over the years, with the development of the Qingque tribe, Wu has experienced more things, and now he is more enlightened.

Before Han Cheng opened his mouth at all, he could already see the clues of the matter just from the change of Han Cheng's expression.

For a time Wu was hit hard.

After all, the matter of using a magnet to absorb iron sand and then make ironware was only thought of after racking my brains for a long time.

I was still so excited about this, I went here to find the Son of God to verify it, but the result was completely different from what I thought.

But apart from attracting iron, this magnet has no other characteristics except blackness!

"Son of God, does this magnet have other uses?"

Wu thought about it carefully, and felt that he really couldn't think of anything, so he immediately gave up struggling and began to ask Han Cheng directly.

Having lived in the tribe for such a long time, Han Cheng already has a very thorough understanding of Wu Zao.

Seeing Wu asking questions like this, he didn't try to comfort Wu. This was unnecessary and too hypocritical.

According to Wu's temperament, even if he felt a little bit lost in his heart, it will get better after a while.

"Witch, this magnet does have other uses, for example, with it, we can use it to make tools that can tell the direction.

This tool I call a compass.

After it is manufactured, one end of this thing always points to the south, so it is called a compass.

As for the four directions of east, west, north, south, only one needs to be determined, and the rest can be determined as well.

With this tool, people in our tribe can rely on this compass to identify the direction when walking outside, without worrying about getting lost. "

Han Cheng explained to Wu.

Hearing what Han Cheng said, Wu felt relieved and nodded accordingly.

"This thing is good, the direction is not chaotic, and it is not easy to get lost. People in our tribe can avoid a lot of danger when they walk outside."

The witch answered the words out loud.

Obviously, he also remembered that when a trade team in their tribe went out, they encountered a dangerous situation.

"Son of God, what is a compass like? Have you made it?"

After sighing, Wu asked Han Cheng again.

"Let me get a simple compass out for you to see."

Hearing Wu's question, Han Cheng immediately regained his spirits. After all, when this thing involved something like physics, Han Cheng was one of the few sources of confidence.

Hearing what Han Cheng said, Wu also became energetic.

Just what Han Cheng said before, the curiosity in Wu's heart was already mobilized by Han Cheng.

He really wanted to see what this magical thing looked like.

With such a great use, it has been stubbornly pointing to the south. Thinking about such a thing makes people feel extraordinarily magical.

And Han Cheng also started to move his hands.

He had already prepared the necessary tools before, so he didn't need to search for them, he could just do it by hand.
