Moreover, it is impossible to make too much money by selling the sound transmission stone. Only the first pot of gold can do it. After that, the business will be divided among the people in the world.

Because there are so many people in demand for sound transmission stones, this thing is considered a daily necessity and no one can live without it.

And when everyone in the entire continent is in need, the Gua Xianmen family alone will never be able to satisfy everyone. If their appetite is too big, they will stretch themselves to death.

The most important thing is that this thing has no technical content. There are too many people who are proficient in rune formations. Give them time and they will figure it out.

The difficulty in making a sound-transmitting stone is not the runes and making methods, but the matter of finding the materials itself.

Jiang Chu still remembered that she had read a miscellany in her previous life, which described the whole process of the birth of the sound transmission stone. In the early days, people relied on talisman paper to transmit sounds. Each time a word was transmitted, a talisman paper was consumed.

Very luxurious.

Later, it became a magic weapon, which needed to be equipped with crystal stones to activate it, which was even more expensive.

It was later that someone accidentally discovered the existence of the Huazhang Stone. That person was a talisman master and tried to carve talismans on this new stone. Only then did he realize that this stone was light but hard, and could retain its own spiritual energy for a long time.

The runes on it also last for an extremely long time.

However, after trying many kinds of talismans, I found that most of them are not easy to use. The talismans themselves do not fit well with the characteristics of this kind of stone.

Until one day, he suddenly engraved the runes for sound transmission, and it turned out to be true!

This became the sound transmission stone.

After that, the sound transmission stone spread, replacing all previous sound transmission tools, and became a must-have for everyone in the mainland.

It's just that the sound transmission stone is a consumable. As the spiritual energy of the runes engraved on it is exhausted, its service life will also come to an end. At this time, it will have to be replaced with a new one. On average, the sound transmission stone's

The service life is about two years.

With so many people, each person will use dozens of sound-transmitting stones in their lifetime, which consumes a lot of picture-zhang stones. There was a time when new sources of picture-zhang stones could not be found, and the production of sound-transmitting stones was in urgent need.

At that time, everyone was eager to find a substitute to replace the lost painting seal stone. However, the strange thing is that although the Xuanji Continent is rich in products and has tens of thousands of materials, there is no material that can replace it.

The status of Huazhang Stone.

Whether it is wood or stone, everyone has tried it over and over, but either the aura of the runes will dissipate quickly, or it will crack as soon as it is put on, making it impossible to use it.

This method didn't work, but fortunately everyone found a new origin of Huazhang Stone, and the output was sufficient, so we were relieved.

The same is true in Yaoxing Continent. The people here may not be able to draw transmission symbols, but they can't find a carrier that can carry them, so they can only use disposable consumables like paper cranes.

Jiang Chu thought that when she was in Yuxiaocheng, she had asked her parents and Uncle Gu about Huazhang Stone, but they all said they didn't know. Besides them, what about the others?

Probably, no one in the world except Jiang Chu knew that the pip stone used as a chair had another useful purpose.

"...Noble? It?"

Huang Yan swallowed his saliva, and when he looked at the pip stone again, his eyes were filled with shock.

Just this idea stone??

Jiang Chu became a noble person just because he discovered that it has other functions?

But you can buy a ship of this thing with one crystal. No, you don't need crystals at all to trade it.

Even because this thing is hard, many people still don't like to use it, and they don't even bother to buy it no matter how cheap it is.

Many people who buy it and use it are actually people who live by the sea and are exposed to wind and sun, so this thing is so cheap.

If the poor use it more, it will become cheaper. If the rich use it more, it will become more expensive. If the rich and poor use something, the price will be relatively stable.

Huang Yan looked at the idea stone and couldn't understand it.

But Jiang Chu was looking at Li Yu.

If he is the only one in the sect who knows runes, then he has hope.

If it was alchemy, Jiang Chu could still ask Uncle Gu for help, but as for talisman, she didn't recognize any of her own people. If Li Yu didn't know it, all plans would be in vain.

Because once you seek help from outsiders, the secret of the idea stone cannot be hidden and will be exposed in advance.

"This is not difficult, you just need to practice. I'll try it first."

Li Yu's drowsiness disappeared after hearing Jiang Chu's words.

Although he has been lazy in recent years, it is because he has no other choice under the pressure of the situation. Even if he wants to work hard and be diligent, what can he do?

Since you are unable to fight, you might as well just live in ignorance. If you don't want to stop reading, just focus and relax, maybe the years will simply pass by and you won't have any more worries.

Later, I became more relaxed and got used to it, and felt that there was nothing wrong with it.

It's just that there is probably still a trace of resentment and unwillingness in my bones, but it has nowhere to put it and can't be released. It doesn't show off at ordinary times and only comes to the fore when needed.

Like, now.

If the idea stone in his hand is the key to the rise of their Gua Immortal Sect, doesn't it mean that the future of the entire Gua Immortal Sect is now tied to his own hands?

Under this kind of pressure, Li Yuteng suddenly woke up, and there was some clarity in his often hazy eyes.

Picking up a pen and paper, Li Yu first became familiar with the pattern of the rune "Jiang Chu" on the paper. After spending a quarter of an hour practicing it until he was most proficient, Li Yu began to carve it.

Everyone stayed with him quietly without making a sound or disturbing him.

When he failed once, Huang Yan would swing his machete to chop off a chunk of the idea.

When Li Yu's spiritual power was exhausted, the great elder would hand over the elixir in time.

Others were staring at Li Yu's hands, watching him pick up the carving knife to carve a stone, watching him stop the carving knife and throw away the waste stone, watching him pick up another stone...

As time passed, everyone seemed to be used to this rhythm, and their eyes became dull.

But suddenly, the hall master Shi Lei's shout brought everyone back to their senses.

"It's done!"

Everyone suddenly sat up straight, and their eyes that were a little dizzy immediately woke up, "What's going on? What's going on?"

"It's done? Is it carved? Let me take a look!"

"Ah, is this rune completed?"

The heads of the sect master, elders, palace masters, and stewards were all gathered together, only staring at the hand of Li Yu in the middle.

There was a translucent stone there. In order to save time, the shape was cut out in a very rough shape, just a square. As for the size, it was about half the size of a woman's hand.
Chapter completed!
