Childhood memories: starting from the magical Ayo

He suddenly stopped and looked at Ye Tian in confusion.

I won’t really be solved by this kid.

If it is really solved, I won’t have to go on patrol every day anymore?

"Can you really solve it?"

Bei Mingzheng asked tentatively.

Ye Tian nodded: "It should be possible."

Bei Mingzheng's face looked strange and he really didn't know what to say.

Not long after, Ye Tian returned to his room.

Back in the room, Ye Tian took out his magic pen and drew a compass.

The compass needle jumped wildly.

"It's useless..."

Ye Tian muttered when he saw this.

It’s not particularly surprising. After all, this is not the Earth. The magnetic field is definitely different from that of the Earth, so it is normal for the compass to fail.

Although the compass was broken, Ye Tian thought of a prop from the Ayo world.

Many planets in the Ayo world also lack the ability to distinguish directions for various reasons.

So there was a planet with more advanced technology that invented an invention.

magnet.

Magnets are divided into mother stones and child stones.

To put it simply, the function is that the mother stone can simulate a magnetic field similar to the North and South Poles of the Earth.

Then just put the mother stone in one place, and use the sub-stones to make a small prop similar to a compass.

The planet that invented the magnet called the prop a compass.

This thing is actually a compass.

Ye Tian planned to draw this, and in the future he would use a compass to determine the direction in the Beiming Snowland.

This thing may not be as advanced as launching a satellite and then using satellite maps.

But this thing is easy to make.

Because the people on that planet also invented a prop, which looks like a box. You just need to put the stone into the box.

The box will automatically process the sub-stones and make them into a compass.

In other words, Ye Tian has to solve the problem of not being able to distinguish directions in the snowy area of ​​Beiming.

You just need to draw the Zi Shi a little bigger or directly draw a Zi Shi mountain, and you can solve the problem of identifying the direction at one time.

To put it simply, Ye Tian actually thinks that high-tech things are too troublesome.

Although he has a genius and can draw anything, high-tech things require a lot of drawing.

Moreover, the people in this world have not been exposed to technology, so he has to explain how things work.

Since he wanted to solve this problem, he had to solve it for everyone in the Beiming Snowland.

There are quite a lot of people in the Beiming Snowland.

So instead of using technology or something, it's better to use magnets.

Ye Tian had no mood to sleep.

He directly took out a star map, which recorded the map of the entire world.

He first needs to use a star map to find a good place to store the magnet.

After looking at the star map, he chose the place to place the mother stone.

It is the valley where the unicorn is.

It is not only the northernmost part of the Beiming Snowland, but also the northernmost part of the entire Yulong Kingdom.

Ye Tian used instant teleportation and headed to the valley.

Then, he took out his inspiration and drew the mother stone of the magnet.

The mother stone is cylindrical in shape, about three meters high and about the thickness of an adult.

Immediately afterwards, Ye Tian knocked the mother stone into the ground.

Ye Tian did not place the mother stone on the ground, for fear that it would be moved away by someone.

But logically speaking, no one would be so idle as to come here and move the mother stone.

I’m just afraid that some little divine beasts might think that some treasure has been taken away.

After the mother stone was placed, Ye Tian went to Baiyu City again.

Directly draw a large piece of stone in Baiyu City, and then draw a pointer production box.

Ye Tian tried to throw in a large piece of stone.

After a few seconds, the stones were transformed into several props that looked like compasses.

The production boxes of the pointer needles do not need to be produced one by one.

As long as you throw in enough sub-stones, you can produce dozens of pointers at a time.

After the pointer is produced, it is round in shape, the size of a palm, black in color, and has a metal shell.

Zi Shi is said to be a stone, but it is actually a special kind of metal.

The outer shell is made of a stone with its magnetism removed. The removed magnetism is not wasted but injected into the pointer.

Inside the disc, the four directions are marked with the words east, south, west and north respectively.

Also, there is a pointer inside, with one end thick and the other end thin.

The thin end is like a needle, pointing to the north at this moment.

With this thing, I won’t have to worry about losing direction in the Beiming Snowland anymore.

Ye Tian played with the compass and a smile appeared on his face.

I declare that Shifang Mingliang can be laid off.

That night, the Baiyu Army produced tens of thousands of compasses using the stones and production boxes provided by Ye Tian.

The main reason is that there are not enough stones left by Ye Tian, ​​otherwise it could still be built.

After all, this thing is too easy to make. Zi Shi just threw it into the box and then waited for him to make it into a compass.

It's more automated than automation.

……

The next day.

restaurant.

Ye Tian looked at Bei Mingzheng and said, "Dad, it's solved. You don't have to go out on patrol anymore."

Bei Ming was stunned for a moment: "Ah?"

Ye Tian took out a compass and handed it to Bei Mingzheng, then told Bei Mingzheng the function of the compass.

The compass is very simple to use. Just tell Bei Mingzheng that the thin part of the needle will always point to the north, and Bei Mingzheng will understand how to use the compass.

Bei Ming was looking at the compass. There was actually such a thing. Why had he never discovered it before?

"Is this a lot?"

Bei Mingzheng looked at Ye Tian and asked.

"As much as you want."

"hiss……"

"Dad, let Bai Yujun patrol for you starting today. While patrolling, I will let Bai Yujun take the compass and sell it to the people in the North Sea Snowland."

Ye Tian looked at Bei Mingzheng and said.

Chapter 8 The main theme is filial piety

"Is it expensive? I only have one request, don't sell it too expensive."

Bei Mingzheng gave an instruction.

He didn't ask Ye Tian to give it away for free.

After all, it takes manpower and material resources to make something.

He couldn't let his family suffer.

However, he didn't want the people to suffer, so he could only hope that the cost was not high and Ye Tian didn't sell it too expensively.

Ye Tian nodded after hearing this.

Cost, what cost? It’s a no-cost business.

Although it was a no-cost business, he did not choose to give it away directly.

The impact of giving it away for free won’t be very good.

If you dare to give people things for free today, they will dare to ask for them for free tomorrow if their compass is lost or broken.

This is definitely an exaggeration.

But there are always such shameless people.

So just trade normally.

Anyway, he won’t sell it too expensively then.

As the two were talking, Bei Mingxue and Bei Minglei came over.

Bei Mingxue came to Ye Tian and asked in a low voice: "Brother, when will you take me out to play?"

"Don't worry, let's eat first."

Ye Tian replied in a low voice.

Bei Ming Lei looked at Ye Tian and Bei Ming Xue in confusion.

You guys actually have a little secret behind my back! ?

No, you are not doing this behind my back, you are actually whispering in front of me! ?

"Brother, what are you talking about?"

Bei Ming Lei had the nature of a child, and immediately asked anxiously.

"Brother, don't ask. We won't tell you."

Bei Mingxue said mercilessly.

Bei Ming Lei: “Ah?”

Bei Mingzheng smiled and said, "Alei, Axue, I have good news for you. Dad may not need to go out on patrol every day in the future."

"Really, Dad!?"

When Bei Minglei and Bei Mingxue heard this, they looked at Bei Mingzheng happily.

Bei Mingzheng smiled and nodded: "Really."

"Great!"

The two cheered.

Bei Ming was looking at the two happy people and continued, "I heard that you haven't been studying hard recently and you've been sneaking out to play. I'll be able to keep an eye on you two from now on."

The two of them froze in place.

"Dad, I actually still want you to go on patrol."

Bei Ming Lei said filially.

"You kid!"
