"This is my latest research and development of the signal device, with the function of signal reception and transmission, the use of 4G signal system, but the size of only a baby's fist, but the signal transmission range can reach 100 kilometers, the ability of signal transmission beyond the signal base station on the earth more than 100 times. Xiaomi introduced Su Yaowen to the signal tower information that had just been developed.

Su Yaowen looked very seriously, he had only heard that the 4G signal tower could only transmit the signal to a kilometer away in an open place, but the coverage of the signal device designed by Xiaomi has been improved so much, and the technology is more than ten years ahead.

Su Yaowen found that the signal device designed by Xiaomi looked like an ordinary round metal sphere on the outside, but there was a mystery inside, and the entire signal device was divided into three parts.

The outer layer is a metal casing to protect the signaling device from unnecessary physical damage, because it is made of fine iron as the main material, which is very defensive, and at the same time leaves a large number of tiny holes on the surface that lead directly to the inside, each less than a millimeter in diameter.

If it is a sealed metal ball, it will weaken the propagation of the signal to a certain extent, so Xiaomi will leave a large number of small round holes on its surface, and also coat the edge of the round hole with a special pigment to prevent the signal from being reflected back.

Without the help of the divine sense, if he wanted to complete such a delicate refining process, with Su Yaowen's current refining technology, it would be impossible to do it at all. In other words, Su Yaowen can only try to refine the signal transmitter after the foundation is built.

The innermost part is the core, which is a smaller round bead, which is densely painted with formation runes, and there is hardly any free space, it is obvious that this is Xiaomi in order to compress the space and cost as much as possible, so the volume of the signal device will be so small.

Because of the full array arrangement, the entire core part is the most important place, if there is a slight damage, there will be problems with the formation inside, and the signal device will not be able to be used, so sufficient protection measures must be added.

The middle part of the signalling device is used to protect the inner core, which is a soft, gelatinous substance, as soft as a marshmallow. This substance acts as a cushion to prevent physical factors such as impact from damaging the core of the inside, and can also insulate some dust or liquids.

This gelatinous substance is modified by millet using a soft metal, which is not only soft, but also has good signal conduction ability, which just wraps the entire core part without weakening the signals sent and received inside.

After reading the design drawings of the entire signal device, Su Yaowen also had to sigh at Xiaomi's brilliant idea.

The core is not much different from the signal towers on the earth, but Xiaomi has drawn a large number of amplification formations on the outside, which increases the power of sending and receiving signals by hundreds of times.

However, because there are too many formations inside, as long as there is a little damage, such as a little damage and lack of formation runes in a certain place, it will make the entire signal device reimbursement.

"Xiaomi, the technology needed for the signal device is too difficult, and we can't do it now. Su Yaowen said helplessly.

"It doesn't matter, we don't have the technology to mass produce mobile phones now, with your talent, there will probably be two years to build a successful foundation, and the progress of mobile phones should be about the same by then. Besides, although this signaling device is very strong, it is always a defect to be reimbursed for a small problem, and it should be enough to improve it in two years. "Xiaomi is not too anxious.

"So what are we going to do next?" asked Su Yaowen.

"These days, I have to upgrade the touch screen of this phone, and these materials have to be bought. Xiaomi made a list, "If we still use the methods on earth to manufacture, we have not mastered that technology, and we will not be able to produce touch screens at all." I plan to integrate the refining techniques and formation techniques of the cultivation realm and draw a visual illusion array on the top of the screen to replace the original screen display. ”

"Visual illusion array?" Su Yaowen hadn't heard of this thing.

"It's a very simple formation, which can be used to image virtually, but the image produced can be seen at a glance to be fake, and there is nothing deceptive, so it is not very important, but it is suitable for us to transform it into a mobile phone screen. "Xiaomi is very happy, if it can really be successfully transformed, the cost can be reduced by more than 50%.

Since you want to buy materials, of course you need spirit stones, although when the sect was in a big competition, Su Yaowen bet that he won and earned more than 2,000 medium-grade spirit stones, but if they want to really produce mobile phones on a large scale, this spirit stone is not even a fraction of it, so they have to hurry up and make money.

Then let's get started! Su Yaowen summoned the bamboo puppets in the storage bag and asked them to start refining the intermediate spirit runes.

One is to make a spirit rune and then take it out and sell it, and the other is to keep some for self-defense, the previous battle with Bai Xingkong, the inventory of spirit runes has been consumed, if you don't replenish some, but the battle is useless.

Although the skill of the bamboo puppet refining spirit runes is good, but there are too many intermediate spirit runes, which will have a certain impact on the price of spirit runes in the sect bazaar, Su Yaowen has begun to consider looking for other money-making skills, or taking out the spirit runes to sell in the big cities outside.

The city outside has a large flow of people, high consumption capacity, and even a variety of materials, which is not comparable to the place where low-level monks haunt the sect bazaar. Moreover, some of the procurement materials listed by Xiaomi just now are not available in the sect market, and they need to be found in cities with more trading varieties.

However, the closest Tianhai City to the main island of the Tianya Sea Pavilion is also on land, and Su Yaowen needs to fly over the offshore sea to get there.

In order to prevent the enemy from using the teleportation array to sneak attack, all sects will not build a teleportation array in their own core place, and the same is true for the Tianya Sea Pavilion. If the people in the sect want to go to other distant places, they need to fly to Tianhai City on the land by themselves, and use the teleportation array to leave from there.

Tianhai City is a subsidiary city of Tianya Haige, and it is about fifty kilometers away from the main island of the sect, which is not very far. If it is a foundation building period monk, it only takes a little more than two quarters of an hour to fly with all his strength, that is, half an hour, which is considered very fast. Su Yaowen's Thousand Paper Cranes were just a means of transportation used by low-level monks, and it would take half an hour to get to Tianhai City.

Although Han Miaozhu took him with him last time, Su Yaowen actually didn't stay in Tianhai City for a long time, and he was not familiar with it, plus it took too long to go back and forth, and it might not be safe along the way, Su Yaowen felt that he still had to find someone to accompany him.

For the sake of insurance, Su Yaowen begged Han Bing'er for a long time before he got the other party's consent to take him to Tianhai City, which is equivalent to having a free driver to pick him up, which is very cost-effective.
