As the first mobile phone in another world, Fang Zheng did not use any raw materials from other worlds, which is why it took him some time to make this thing.

This phone includes all the basic capabilities of smartphones of Founder's era, such as taking pictures, recording sound and video, group messaging, video conferencing, phone calls, text messages, and WeChat.

By the way, Fang Zheng also thoughtfully included a small fruit-cutting game.

Of course, due to the performance limitations of mobile phones, Fang Zheng has not had time to add mobile games to it, but can this extinguish Fang Zheng’s burning desire to spend money?

Of course not!

Founder had already designed it when he was developing the system!

The entire mobile phone system is divided into a free version and a paid version. The functions of both versions are basically the same, but there are some minor differences. For example, the free version of the system can only take ten photos per day, record 30 seconds of video and sound, and the video chat time cannot exceed five minutes. The paid version can take unlimited photos, record videos and sounds, and there is no time limit for video chats.

Anyway, there is no consumer association in this world, let alone antitrust law. I can set prices however I want. Are you going to bite me?

Fang Zheng has already decided that after informatization is implemented in the main world, he will promote financial networking services, and then develop electronic currency - and then he can start mobile games...

Hehehehehehe…

"How did you do that?"

Looking at the phone in her hand, Colette's surprise was beyond words. To be honest, if Fang Zheng gave her a product from another world, Colette might not be so surprised. After all, there are countless planes in the world, and there are all kinds of strange things. This is normal. Even when Colette took the phone in her hand and activated it, she could guess what technology was used in it.

What is carved inside is a magic circle!

That's right, Colette could feel the continuous fluctuation of magic power coming from a fingernail-sized area in the middle of the phone. This was very familiar to her because it was the magic power fluctuation of the magic circle! So Colette quickly figured out the function of this phone. To put it bluntly, it activated the magic circles according to the user's touch and achieved similar purposes.

For example, the voice is heard through the teleportation technique, the image is shown on the screen through the illusion technique, the flashlight is the eternal flame, and so on and so forth…

However, it was precisely because of this that Colette was so shocked.

You know, although the levels of these spells themselves are not very high and the magic circles are not very complicated, there is a problem, that is, they are integrated and used together!

How is this done?

You have to know that integrating spells of different levels of magic networks is an eternal problem. There are so many wizards in the world, and none of them is stupid. Fang Zheng was not the first to come up with the idea of ​​superimposing all the magic circles of spells together and triggering them at once. Hundreds of years ago, wizards came up with this idea.

However, up to now, no one has accomplished all of this.

But now...it has been completed by Fang Zheng!

The most important thing is that these magic circles are not only unified and superimposed, but also shrunk! Generally speaking, magic circles are not small. The smallest one is the size of a palm, and the largest one can be as big as a city.

However, here, these magic arrays, which were originally of different sizes, were all concentrated on a small magic crystal the size of a fingernail!

"I had someone redesign it and then used special equipment to carve it on."

Facing Colette's question, Fang Zheng shrugged and gave an answer.

Just as Colette thought, these magic circles themselves were not difficult. The difficulties she thought of were indeed insurmountable for most people, but that didn't mean that no one could do it.

For example, Nymph...

That's right, these magic circles were redesigned by Nymph. As an artificial angel, although Nymph herself cannot use magic, it is not difficult for her to simply draw pictures. As for etching these magic circles, it is even simpler. Among the many worlds where Fang Zheng is, there are many worlds with advanced technology. Find some micro-etching devices, make some modifications and adjustments, and then you can directly start industrial production.

"You mean, you have equipment that can etch magic circles in such a super small range?!"

Although Fang Zheng didn't say it directly, Colette is the chief of the necromancy department after all, and her brain is certainly not stupid. Now she can use instruments to observe the cells in the blood, so it seems normal to have a similar instrument that can etch magic arrays on it?

Thinking of this, Colette's eyes suddenly lit up.

"Can I use that kind of equipment? I want to try to etch a magic circle on the cells to see the effect..."

"That may be difficult..."

Hearing Colette's question, Fang Zheng hurriedly waved his hand to interrupt Colette's request, and wiped the cold sweat from his forehead. Sure enough, the mages in this main world are more terrifying than each other. Look at what they are thinking. Is it human to carve a magic circle on cells? What do they want to do by carving a magic circle on cells? !

Seeing Colette so excited just now, Fang Zheng was considering whether to sell a few of the instruments, but now he has completely given up on this idea. It is safer to keep this thing in his own hands, otherwise who knows what the wizards in this world can do with it.

"Okay, so what's the use of it?"

Seeing Fang Zheng's reluctance, Colette was somewhat disappointed, but she soon picked up the phone and looked at it carefully. In response to Colette's question, Fang Zheng shrugged.

"It allows you to connect with other people. Let's say, if both of you have mobile phones, then if you want to contact her, you just need to dial her number and you can get in touch with her instantly. You can also communicate with each other through text and even send videos..."

As he spoke, Fang Zheng took out another cell phone, opened the message interface, and sent a text message to Colette. Soon, a "ding dong" notification sounded, and Colette curiously opened it and immediately saw the message.

"How's that? Did you see what I said?"

“This…this…”

Even though Colette was considered a vampire elite and had been the chief of the White Tower for who knows how many years, she was actually shaking with excitement like a child when she looked at the phone in front of her. How could she not understand what this meant!?

“What is the effective distance?”

"If conditions permit, even if you are in the Kingdom of Magic and the other party is in the Kingdom of Holy Religion, you can contact the other party with just a phone call. Of course, you can also send text messages, WeChat, or directly video chat."

"Conditions permitting?"

As a mage, Colette certainly wouldn't be carried away by excitement, and she reacted quickly.

"And what are the conditions?"

"That's it."

As Fang Zheng spoke, he pointed to the crystal tower floating in the air outside the window.

"Mobile phones can only have signals within its radius. If there is no crystal tower, there will not be enough signal to connect. Of course, that will also be taken away and sold."

Fang Zheng seemed very calm about this.

Isn't this normal? If you sell mobile phones, what's the point without base stations? However, is there any way to build base stations for free?

If you calculate it this way, building base stations costs one wave of money, selling mobile phones costs one wave of money, and unlocking VIP charging items costs another wave of money.

Selling one machine three times, it’s simply too much profit!
