"Didi!" Just as Yu Wei and the others were eating, a burst of ticking came from Yu Wei's body.Yang Yujie and the others all looked at him, looking at him curiously.

At this time, Yu Wei took out a square object from nowhere, and there were several protruding buttons on the square object. He pressed a red button, and then a video appeared in front of everyone.

"Brother, where are you now? Aren't you coming to eat?" The figure in the image inside is Qin Keqing, and at this time she is standing outside the house talking to Yu Wei.

"Oh, I met friends from the village today, so I took them to eat in the cafeteria. I'll take them to my place later." Yu Wei said to Qin Keqing.

"Okay, you guys eat first, I'll go to your place to make preparations, and I'll entertain your friends later. That's it!" Qin Keqing finished speaking, and then her figure disappeared from the video, and Yu Wei was also in the square Pressing the blue button on the object ended the call.

At this time, the people around Yu Wei were all staring at the square object. This thing is so magical that they can see the figure of the other party and hear the other party's speech at the same time.

Many people in the cafeteria saw the conversation between Yu Wei and Qin Keqing. After Yu Wei finished the call, many people ran to him and looked curiously at the square object in Yu Wei's hand.

"Brother Wei, what is this thing! It's amazing, you can still see the other party, and you can also hear the other party's speech." Yang Minghui who was sitting opposite asked Yu Wei curiously.The others also looked at him expectantly.

"This is a wireless phone. No matter where you are, as long as you have it, you can contact the other party and see what the other party is doing!" Yu Wei explained to them.

"Wireless phone?" Yang Minghui and the others obviously don't know the meaning of this word, but they know that this thing is very magical, and they can contact each other at any time. Regarding the matter of the hunting team, if they had this wireless phone, they would not have to send so many people up the mountain to look for it, but they could know their situation through the wireless phone.

When other people heard Yu Wei's explanation, they immediately thought of many things. For example, if everyone has a wireless phone during the adventure exercise, their safety will be increased several times, and their chances of survival will be greatly increased. .

"Brother Wei! Do you still have this wireless phone? We want to buy it!" At this time, a student whom Yu Wei didn't know asked.

"It's time to be decisive. This thing has just been made, and many functions are still immature. I will let everyone know when the experiment is completed."

Because last time Qin Keqing searched for him for a long time, Yu Wei also thought of the wireless phone in that world. If he had a wireless phone at that time, then it would not be so troublesome to find someone.That's why he thought of making a wireless phone by himself.

And because there is a memory crystal ball in this world, the imaging principle is also easy to understand. After all, he installed the security monitoring system in the current library, so the wireless phone thing will not be difficult.

The only problem is how to connect one phone to another, is there any wireless satellite in this world.By chance, he stood on the square of the college, looked up at the sky, and saw the top of the library, and suddenly an idea popped up in his mind, to put the wireless receiving and forwarding thing on the top of the college library Isn't that all right? In this way, as long as you are within the range of the college, you can receive the signal of another phone.

The wireless transponder receiver is equivalent to the management system of the library database. Through him, he can monitor the signals within the range, and the wireless phones can communicate with each other, so he made two wireless phones to test the effect.

The problem of signal connection is solved, and then there is the problem of energy, and this problem is even more obvious. There are many energies that can be used in this world, among which spirit stones can be used, and they are the most common.There are upper, middle and lower grades of spirit stones, as well as top-grade spirit stones, and even high-level fairy stones and fairy crystals. What is not lacking is energy.

Through experiments, a low-grade spirit stone can supply a wireless phone for at least three years, a middle-grade spirit stone can supply it for at least ten years, and a high-grade spirit stone can supply it for 50 years.So this problem was solved quickly.

Since the size of the wireless phone is small, if a whole piece of spirit stone is used as the energy source, then it is impossible to hold it, which will greatly increase the size of the wireless phone, which is not very convenient to carry, so the energy storage device is changed After a while, one spirit stone can be divided into five parts, and one part can be put into the wireless phone each time.And a phone can put up to three copies at the same time.

After a few days of experiments, the functions of the wireless phone are relatively good, and there are no shortcomings.At first, he just thought it would be enough for a small number of people to use it in the academy, but he didn't think about promoting it on a large scale, because that would require a lot of preparation and a lot of manpower and technical support, which would be troublesome.But today in the cafeteria, so many people know about this thing, and many people want one.

Now that there is the first one, there will be the second one, so more and more people are sure to use it, and he also promised that they will launch it, at least now it can be used within the academy, as for places outside the academy , It is still open to discussion, and that is also a matter of the future.

It was promised that they would launch wireless phones, and then mass production would be required.

After dinner, Yu Wei took Yang Yujie and the others to the teacher's residence. At the foot of the mountain, Yu Wei pointed to the eighth house on the top, and then took out the magic amulet given by the dean and stuck it on his body. Fly up ahead with them.

Yang Yujie and the others all have cultivation bases in the foundation building stage, and they can all fly with swords. Each of them calls out a sword and flies forward.

Yu Wei led them into his house, and as soon as he walked in, he saw several plates of fruit on the table in the hall.The house was also cleaned cleanly, and it was obvious that Qin Keqing did it.

"You guys are back! You sit down for a while, I'll wash a few more fruits." Hearing the sound, Qin Keqing came out of the kitchen to greet her, and still had some fresh fruits in her hand.

As soon as several people entered the house, they looked around curiously. The house here is bigger and better than the house in their village.Now that Yu Wei is living here, they are very envious, and there is a beautiful sister taking care of him, what a happy life this is!

When Yang Yujie saw Qin Keqing, jealousy surged in her heart for no reason. She didn't like her getting close to Yu Wei, even though she was his older sister, and this older sister was not her own.

"Brother Wei, I'll help Sister Keqing!" Yang Yujie said to Yu Wei, and then ran into the kitchen to help.

Yu Wei continued to take other people to visit other parts of the house.After a while, Qin Keqing and Yang Yujie came out of the kitchen, talking and laughing at the same time, looking like good sisters.

"Everyone is coming down to eat some fruit!" Qin Keqing yelled upstairs.
