"Because when the Great Elder demonstrated the use of the Lingering Stone to record images, I caught a special kind of fluctuation, and this fluctuation has a certain regularity. Then I wondered if this fluctuation was a signal that was necessary to record some kind of image similar to electromagnetic waves, and if so, then there must have been similar fluctuations when the Great Elder demonstrated the use of the image of the Lingering Stone. Xiao Jiu explained.

"Well, no wonder you were so excited, you already had the idea of how to make a video phone out of the Gram Stone long before we got out of the cave. He Wei said.

"Well, I did have some ideas at the time, but I wasn't sure. So I immediately asked the Great Elder to demonstrate what the image stone looks like when the image is used on the Shadow Stone. Xiao Jiu said, "As a result, things are just as I imagined, there will be that special fluctuation when the image of the Lingering Stone is presented, and the frequency of that fluctuation is exactly the same as the fluctuation frequency that occurs when the Lingering Stone records the image!"

"So you came up with the idea of using wires to transmit this fluctuation, to connect two lingering stones that don't have much to do with each other, and to use one to record the image while the other presents the image recorded by the former?"

"That's right. Xiao Jiu said happily, "Actually, whether it is a walkie-talkie or a video phone, it is a machine used to decode electrical signals with certain rules. The regular fluctuations I had detected made me think that the Gramograph Stone works in a similar way to a walkie-talkie or a videophone. So I wanted to try it out and see if I could transmit those fluctuations directly to another gramograph stone without any processing, and it would have the same effect as an electrical signal. ”

"I guessed yes at the time, and then the facts proved that my guess was right!"

At the strong request of Yu Lan, Xiao Jiu briefly explained, and it was able to discover the process of using two lingering stones and a wire to transmit images. Although most of the wording in Xiao Jiu's explanation was actually only understood by He Wei, he could barely understand some of Youlan and the three elders...... Well, the two elders were still shocked by Xiao Jiu's words.

"Hmph! It's just a useless wire to connect the two Lingering Stones together, not to mention the distance of the teleportation, just the transmitted image is completely blurry, so that people can't see what it is! This level of method of transmitting images, that is, it looks very interesting, in fact, when it is actually used, it has no substantive use at all!" the Third Elder snorted coldly.

Although the three elders who were "hammered" because of their mouths before, when they say these things at this time, they can't help but feel a little nitpicky and deliberately find fault in it. However, everyone in the big group understood that what the three elders said was the truth.

Everyone has seen the images that were transmitted by that wire just now, and compared with the images recorded by the normal Lingering Stone, it is not only very blurry, extremely difficult to see the specific scene, but also extremely unstable, and it seems that it may disappear at any time. If there is a real need to use this method of image transmission to transmit images in real time, it is really doubtful that this level of image transmission can achieve the effect it should have.

"Hehe, if the three elders think that the video phone we want to transmit images in real time is only capable of transmitting images to this extent, then it is a big mistake!" He Wei said with a smile.

"Hmph! Video phone, what is that? I haven't seen it! I only know that the method of transmitting images that you are using now has no practical effect at all, and is worthless!"

"Who said it wouldn't have any effect? Didn't you see it just now? We really did use that method to complete the real-time transmission of images!" Xiao Jiu retorted to the Third Elder.

"How can that level of image be considered ......"

"Third Elder, there are two if there is one!" Xiao Jiu interrupted the words of the Third Elder, and said earnestly, "Do you think that under the condition that this method can indeed complete the real-time transmission of images, I will not be able to improve the effect of this real-time transmission on the original basis?"

"You...... You mean......" The third elder couldn't help but shudder when he heard some possibility from Xiao Jiu's words, and then asked in a trembling voice, "Can you make the image transmitted in this way clearer?!"

"I guarantee that it is as clear as the image you recorded with the Gem Stone!" Xiao Jiu said confidently, "Moreover, I can't help but make it able to transmit clearer images, and I also want to expand the teleportation distance infinitely! In the end, even if it is thousands of miles apart, it can chat as if it were sitting face to face!"

"Thousands of miles and thousands of miles ......" The three elders were shocked, almost completely losing the ability to think, and could not say anything other than muttering and repeating what Xiao Jiu said.

"Alas, I should have thought a long time ago, with the wisdom of Little Nine Girl, if she didn't want to make a magic weapon with the magical effect of earth-shattering ghosts and gods, how could she waste so much energy on such a small thing as a lingering stone?" the Great Elder sighed loudly.

After listening to the Great Elder's praise, Xiao Jiu and He Wei smiled and said nothing. Then, He Wei looked up at the darkening sky and said, "It's not early, we're going back." Blue girl, elders, I need to travel far away in a while, and then everyone here in Dragon Valley will need to worry a lot. ”

"Hey, you're going far away, where are you going?"

"Go to the Valley of the Medicine King for medical treatment. He Wei felt that there was nothing that could not be said about the purpose of this trip, so he replied truthfully. However, as for who he wanted to seek medical treatment, He Wei did not say much.

"Hmm, Medicine King Valley. Youlan nodded, and then looked at He Wei thoughtfully, "Since you need to go to the Medicine King Valley for medical treatment, what needs to be treated must not be a small problem." But you don't look like you're sick. Is it to seek medical treatment for others?"

Regarding this question of Youlan, He Wei naturally could only smile and say nothing. Yulan also seemed to have expected this outcome, so after snorting softly, he didn't ask any more.

"In short, I don't know how long it will take me to go, and I won't be able to come back anytime soon. At that time, if there are any variables on the side of Dragon Valley, please ask the Blue Girl and the elders to bother more. He Wei bowed down again.
