It's possible to practice magic this way, right?

The four people present all opened their mouths wide and looked at the photo stone in disbelief.

The reason for this is that when they look at this scene, it is as if they are seeing Xiao Wu really swinging her sword to cut the sea in front of them. They can even feel Xiao Wu's fighting spirit and the spatial power attached to this sword.

Although it is very weak and cannot be compared with watching it live, but having it and not having it are two completely different things.

"This...this...what is going on?" Huo Jin asked in surprise.

No one answered him. At this moment, Lin Li and Dongfang Jing were looking at Xiao Wu's hand and the pen she was holding in surprise. Even Xiao Wu herself looked at her hand in disbelief.

Obviously they all realized that this was caused by the signature using sword techniques.

"Xiao Wu, you give it a try." Lin Li said quickly.

Xiao Wu came back to her senses after hearing Lin Li's words. Just as she was about to try another one, she saw Huo Jin had already placed another image stone in front of her. Apparently, he also realized what was going on.

Xiao Wu did not start signing directly. Instead, she activated the photo stone first, played the picture once, and confirmed that this was just an ordinary photo before she started signing on it.

After signing, the photo stone was activated again.

Lin Li looked at Xiao Wu in the picture and couldn't help but say, "Sure enough, it's really because of the sword technique that she signed."

"Can't the Photo Stone just record images and sounds?" Lin Li asked.

Hearing Lin Li's question, Dongfang Jing said: "It seems so. At least the fighting spirit and the power of law can be left."

"Why has no one ever discovered such an important thing?"

Huo Jin said, "How did you find out? Who else but you would think of signing the photo stone with fighting spirit and the power of law? You should know that the photo stone is actually quite fragile. Not to mention fighting spirit and the power of law, you can just find a small hammer and smash it into pieces."

Lin Li looked at the two signed photo stones and said, "No, selling these photo stones for only 999 gold coins is too cheap. We need to raise the price. We must raise the price."

Huo Jin also said, "Yes, you have to increase the price. You can't just buy it for 999 gold coins. This is a photo stone that contains the power of fighting spirit and space law. If someone with high talent sees it, they might really be able to comprehend something."

"Increasing the price? Shouldn't the sale be banned? I think it's better to just sign your name casually." Dongfang Jing said.

When Huo Jin heard that he was not allowed to sell it, he immediately became anxious.

"Not selling? No, I can't. I'll lose so much gold coins. How can I just give up such a big business like this?"

Lin Li also felt that Dongfang Jing was right, but he thought that Xiao Wu's fighting spirit could not be preserved forever.

"Don't jump to conclusions. We still have some experiments to do. I don't think the fighting spirit and the power of the law will remain there forever."

"Let these two image stones play in a loop, and let's take a look first."

"it is good."

The four of them just stared at the two photo stones, looking at them over and over again.

"It faded at the beginning." When it was played for the 15th time, Lin Li found that the fighting spirit and the power of laws were beginning to weaken.

By the 22nd time, it had completely disappeared. The other one also completely disappeared by the 23rd time.

Lin Li breathed a sigh of relief when he saw that there were only about 22-23 times, and then said, "Fortunately, if it is only in the first 20 times, then there is no problem. It can be sold, and this is the best anti-counterfeiting mark."

"Xiao Wu, try signing with a little more force. It would be best to find the maximum force you can use without destroying the image stone."

Xiao Wu listened to Lin Li and started signing again. However, due to the increased strength, she broke several in a row. After breaking more than ten, she finally mastered the strength.

After testing, it can be played continuously for more than 100 times with the maximum force. The key is not the difference in quantity, but the difference in quality. The greater the force, the more obvious it will be during playback.

"Haha, good, very good." Lin Li said happily when he saw the result.

"Xiao Wu, press this strength for 9 signatures, then go a little lighter, and you can play about 50 signatures about 60-90 times. The rest are all signed with the strength at the beginning that can only be played more than 20 times."

At this time, Huo Jin said, "Brother Lin Li, I feel bad for only giving you 40 for such a good thing. You see... this amount is a little small. How about we add a little more? Don't worry, we will split the money earned from the photo stone in half."

Lin Li thought for a moment and said, "40 is indeed a little too little. I was only going to sell 1888 of them. I was afraid that if I sold more, I wouldn't be able to sell them all. It's called a collectible, but it's actually just an ordinary photo stone."

"No one would believe those legends that one can understand something just by looking at a video. But this is different. Maybe one can really understand something from this."

"Especially since Xiao Wu's swordsmanship contains the power of the law of space. This is the rarest ability. It is not only useful for warriors, but also for mages."

"How about this, the number is increased to 3888, and you just give me 200 million gold coins. As for how much you want to sell this one for and how to sell it, it's up to you. I won't ask any more questions."

"However, the number of these 9 diamond collector's editions and 90 super collector's editions cannot be changed."

"Okay, okay, that's settled. Looks like the sales scheduled for tomorrow will be cancelled. I have to go back and promote it again. This is not an ordinary photo stone. It will definitely be a big hit."

"By the way, when you promote it, you must clearly state the number of times each photo stone can be used and the degree of effect it can provide. This will make the advanced versions more precious."

"Of course. We dwarves value integrity when doing business. We will never engage in false advertising."

Huo Jin was stunned when he said this, then he looked at Lin Li and asked, "Well, can we get two more copies of the Diamond Collector's Edition? I want to keep one for myself, and don't you want to keep one for yourself as a souvenir?"

"Okay, then add two more. But don't number them."

"Don't worry, I understand this."

After saying that, Huo Jin ran out to order a new photo stone.

Dongfang Jing saw Huo Jin go out and asked again, "Is it really okay to sell this kind of photo stone?"

Lin Li smiled and said, "Don't worry, it's only effective for the first 20 times, and the effect is very mild. It's not that easy to comprehend something."

"Didn't you say that many dwarves were watching Xiao Wu practice swordplay? Did you see a few dwarves comprehend the laws of space?"

"Even if someone with exceptional talent can really figure out the law, that's fine. How many people like that can there be?"

"As for the 99 advanced versions, they are real collector's editions. I don't believe that those who bought them would be willing to use them directly."
