When carving the runes, the runes were still intact on the stone, but after they were successfully carved out, the runes were activated and shrunk in glory, leaving only a small pattern like a fingernail to prove this.

There are traces of runes on the object.

At this point, the runes are invisible, and the specific rune patterns alone are not enough to know the rune marks left behind. Even if someone obtains them, they cannot get a full picture of them.

It is precisely because of this that Jiang Chu said that Li Yuhui Fu was the best, and the Gua Xian Sect was able to regain its vitality because of this.

Because even if this thing is sold, others will not find out the secret of the runes in the first place. They will always have to spend some time to ponder and test it, and by the time they find out, the Gua Xianmen has already

I made my first pot of gold and got my reputation out there.

"It's finally done...but what's the use of this thing?" Li Yu finally succeeded and breathed a sigh of relief, but then he became confused.

He didn't create the rune himself, and he didn't recognize it. Even though he had put the rune on it, he still didn't know how to use it and didn't know its use.

"You make another one."

Jiang Chu said.

Li Yu started carving again with doubts.

After Jiang Chu observed it, he discovered that Li Yu probably needed to take a break every time he carved a dozen or so sound transmission stones. Because he was just testing and time was tight, he relied on taking pills to maintain his spiritual power.

Jiang Chu estimated that if he didn't take medicine and only relied on natural rest to restore his spiritual energy, he would need to rest for about half an hour after being exhausted once.

In other words, if everything goes smoothly and without taking any pills, he can make more than a hundred sound transmission stones in one day.

It is not difficult to make the sound transmission stone, but the runes are new to him, so it is a little slower to draw. In addition, the pip stone is hard and not easy to cut, so it requires some extra effort.

Only now did Jiang Chu remember that there was actually a "softening" potion specifically used on the stone. As long as it was applied on the stone before carving, carving would be as easy as carving on wood!

She wrote down the ingredients formula needed for the potion on paper and gave it to Zhu Zhenzhen, who asked someone to purchase it.

Li Yu just carved no less than forty or fifty pip stones. Although he failed because he couldn't find the feel, so many attempts were not in vain. After one successful experience, he quickly made the second one.

So, Jiang Chu showed them how to use the sound transmission stone in public.

The method of using the sound transmission stone is very simple. You must first identify its owner by dripping blood and mark your own sound transmission stone. Then, as long as you leave your spiritual imprint on the other party's sound transmission stone, you can contact the other party anytime and anywhere. Here

Just leave the message and you will receive it soon.

Jiang Chu and Li Yu stood at both ends of the meeting hall holding hands respectively. At this distance, they need to raise their voices to hear each other. If they don't raise their voices, the other party can only hear the sound but cannot hear it.

What did Qing say?

Others also stood beside them in two parts, staring at the stone in their hands with some anxiety.

Jiang Chu actually said that this stone can transmit sound, and as long as another person speaks, they can be heard quickly!

This is simply making people question their lives, because even the Paper Crane Sound Transmission they think is very magical and easy to use. As for other faster sound transmission methods, it is not that there are no, but the cost is too high and everyone cannot afford it. Only those who have

Only families with money will use it.

But now, a small stone can replace those advanced sound transmission instruments?

Or...the idea stone that they even despise even if they use it as a bench!

However, when they heard the voices from the people standing on the other side of the meeting hall, they were all shocked.

The sound will be slightly different from what you hear face to face, probably because there is a little noise, but it does not prevent you from hearing clearly, nor will it be difficult to identify because of the noise.

"It's really like this! How is this possible..."

The great elder took a step back and looked at the sound transmission stone in Jiang Chu's hand with disbelief, as if it was some kind of scary exotic treasure.

"Is this the sound transmission stone? It's really magical!" Hall Master Tan Xiu's eyes were bright, "With it, wouldn't our Gua Immortal Sect be able to make a lot of money?"

"Are we going to get rich?"

Huang Yan's lips trembled, his voice trembled, and his eye circles were red.

Other sect leaders make money from the sect, but he is better off. He has been subsidizing the sect for so many years, and he has almost wiped out all his own wealth!

If it weren't for his family's great business and his parents leaving behind a large sum of crystal stones and real estate and shops when they passed away, he wouldn't be able to survive now!

But now, the Gua Xian Sect that he has been working so hard to support can actually make money on its own??

This feeling is like you have been raising a stupid son, serving him every day, and for this you have to endure the mocking looks of others.

But suddenly one day, the stupid son is no longer stupid. Not only is he not stupid, he is smarter than everyone else, and he can make money to support you!

Huang Yan shed tears of excitement and joy like an old father.

"You can make a fortune, but probably not in the long run."

The steward Wang Di, Zhu Zhenzhen's husband, was also very happy, but then he came to his senses and shook his head.

"Why?" Huang Yan asked while wiping away tears.

"This business is too big for us to handle, and it's so simple to make that others will do it sooner or later."

Tan Xiu said.

Others gradually calmed down and began to ponder the matter.

Li Yu is only a half-baked talisman master. He has learned a few things outside of the hexagrams because of his personal preferences, but even he can master the talisman of the sound transmission stone proficiently after trying so many times.

Then another serious talisman master would do better and be more efficient.

From this we can see that this rune is definitely not difficult. If this is the case, can other runes be figured out by themselves?

The runes are not difficult, and the materials are more common. You don’t even need crystal stones to trade the idea stone!

In other words...anyone can do this job, not just their Gu Xianmen.

It's okay if you don't trade. Once you start trading, other people will first know that the transmission talisman can be made with the idea stone, and then spend time pondering the runes. In this way, the materials and runes will be available, and the business will not be saved.

"We can't monopolize the business, but we can take advantage of it and make a profit first." The great elder stroked his beard, "But before that, we need to get all the ideas!"

Their Gua Xianmen really can't afford ordinary things.

But the idea stone... haha, that really works.

First, buy the entire Miaoyue City, and then go to several seaports in neighboring cities to transport theirs back, so that all the nearby idea stones are in their hands.
