"Yes, I'm talking to you right now with my comm headband. How about the pen "Fun" Pavilion www.biquge.info? What is the quality of the communication? ”

"The signal strength is ...... The attenuation rate is ......"

Xiao Su reported a series of data, and finally said with satisfaction: "The clarity and attenuation of signal strength are very perfect, and the 'Psionic Power Dual-mode Dual-Standby Communication Headband' refined by my father has been a complete success!" ”

"Very well, I'll go back to the refining room right away and test the signal amplification and anti-interference capabilities."

"Yes, father."

Xiao Su before couldn't contact Yang Chen in the refining room. Especially when refining weapons.

Because in order to create a purer energy field environment, Yang Chen took measures to weaken various energy fields in the refining room, including electromagnetic waves, which were also reduced a lot. These measures are mainly used in the refining furnace, but there are also certain measures in the refining room. This will greatly reduce the electromagnetic waves, resulting in a very bad signal.

In addition, if the spiritual energy fluctuates too strongly when refining the weapon, the electromagnetic waves will be interfered with, and the original receiver will not be able to receive them.

What Yang Chen had to do now was to open the refining furnace and talk to Xiao Su at the same time.

He hadn't turned off the refining furnace in the first place, but now in the refining furnace, the materials were actually still being processed, and he left the Great Sunlight Mirror inside to provide the true fire of the sun.

After returning to the refining room, Yang Chen tried to call a few words: "Xiao Su Xiao Su, can you hear me?" ”

The voice in my ears was a little noisy: "Yes Father, I can hear it." ”

When Xiao Su was halfway through speaking, Yang Chen's heart moved, and he switched the listening mode, and the voice in his ears became a sound in the sea of knowledge.

Of course, the communication headband is different from the previous one, and there are two modes for listening: broadcast mode and sea knowledge mode. The broadcast mode can directly make the voice outside, or it can make the sound heard by Yang Chen by shaking the skull without the outside world noticing. The sea knowledge mode can directly project the sound into Yang Chen's sea knowledge, and it will be directly perceived by Yang Chen, which will be even more difficult to detect.

"How's the clarity?"

Yang Chen said the word "clarity", but the rest was said directly through Zhihai and in the way of "thinking" in his heart.

These are the two communication modes of the communication headband. One is also an ordinary voice mode, the sound mode includes the laryngeal vibration, which is a mode in which the vocal cords do not make a sound but only vibrate, as well as the normal speaking mode, and the other is also the sea knowledge mode, through the way of "thinking" in the sea of knowledge, talking to Xiao Su.

"Good clarity. Compared with before, there is a slight noise, but it does not affect the normal call. ”

"So now let's test the image and video communication functions."

Yang Chen walked in front of the refining furnace, and while investigating the operation of the refining furnace, he visualized a pair of images and scenes in the sea of knowledge.

The image is static, and the scene is a moving video.

"Xiao Su, identify the images and videos that I have transmitted now, mark their location in the database, and compare the clarity."

That's right, these images and videos transmitted by Yang Chen are all original information in Xiaosu's database, so that it is convenient to compare.

"Okay, father......"

With the quality of Yang Chen's mental power, the reaction was quite fast. A total of 100 pictures and 100 videos were transmitted in a short period of time.

Then, after only three seconds, Xiao Su began to answer: "The path of the No. 1 picture in the database is ...... The sharpness is about 3% blurred compared to the original image......"

"Picture No. 2 ......"

"Picture No. 3 ......"

“……”

"Video ...... No. 1"

"Video No. 2 ......"

"Video No. 3 ......"

“……”

Finally, he concluded: "On the whole, the data transmission is basically error-free, but there is a difference of 2%-5% in the ambiguity, excluding the ambiguity error generated by the owner's memory, the overall ambiguity is about less than 0.1%, and the important details are basically not lost, which is satisfactory enough on the whole." ”

After all, human memory patterns are different from those of computers. So it's impossible for humans to write down all the details and transmit them. Because human memory is a kind of memory with a measured focus, it is quite different from the memory method of a computer, which saves all data. So this ambiguity is inevitable.

The key is that important details are left untouched.

"Let's test the image and video reception capabilities."

"Good father, I will also send a hundred pictures and a hundred videos to my father, and my father will identify ......"

Soon, Yang Chen's sea of knowledge was projected with a hundred lifelike pictures and a hundred immersive videos.

Although on a computer, the pictures are clear enough, this lifelike and immersive is not there. Again, the human brain automatically optimizes these images and videos.

Or to use a common phrase, it is called "brain supplement".

Of course, with Yang Chen's control of the brain, he can turn off this function of the brain and stop brain supplementation.

In any case, the transmission and reception functions of image and video have passed perfectly.

Next, Yang Chen also conducted a test of psionic wave transmission.

The so-called psionic wave communication is actually the use of the so-called communication spells and the principles of Dao talismans to communicate.

The advantage of teleportation is that it is very likely to involve the principle of quantum communication, which can exceed the speed of electromagnetic communication at a speed of only 300,000 kilometers per second.

On a small Earth, and even in the entire Earth-Moon system, this speed latency is very low, and real-time communication can basically be achieved. But once you step into the vastness of space, you are in big trouble.

The communication between the Earth and the Sun, that is, one astronomical unit, takes more than eight minutes. The fastest communication time between Earth and Mars requires a delay of about three minutes, the slowest time delay will even reach about 22 minutes, and the average delay is about 12.5 minutes. It's nothing in normal times, but at critical times, with such a long delay, the daylilies are cold.

But spells are different. It can be reached instantly, no matter how far away. Later studies have shown that with the interstellar technology of the Trojan Federation, an army has been held from the mainland of the Trojan Federation to the earth for nearly a hundred years. However, there was no delay in the communication between the invading Trojan army and the rear. This shows that the communication under the Lingwu technology can communicate in real time at such a long distance.

The principle of the communication spell is no different from that used by the Trojan Federation, but the level of technology used is very different, which makes it difficult for the earth's communication spell to travel thousands of kilometers away, so that now the communication in the metaphysical world has almost completely abandoned the traditional communication spell, while the Trojan Federation can cross the long starry sky.

In the currently known theories, Yang Chen can only compare it to quantum communication.

Although modern technology is also working on quantum communication, it is still a long way from civilian use. Moreover, quantum communication cannot achieve the function of transmitting purely spiritual things such as thoughts for the time being, while communication spells can.

In this regard, it is also very promising. In later generations, there are still achievements in the research of communication spells, although there is no way to make the effect of communication spells beyond the earth-moon system, that is, the distance of one light second, but within a light second distance, it is basically possible to reduce the cost and popularize the general, and it is stable enough.

But to do this, a perfect psionic wave communication network is needed, and this condition is not yet available, so Xiao Su can only temporarily manipulate the pre-prepared spiritual power talisman to activate the teleportation talisman for communication.

The functionality in this regard has also been largely passed.

"Good!" Yang Chen tested the other two magic weapons again, and found that the performance was basically the same, and finally concluded satisfactorily: "This test was a complete success. I announce that the 'Experimental Psionic Power Dual-Mode Dual-Standby Communication Headband' has been successfully developed! ”

The so-called experimental version is the only version of this headband. Then, Yang Chen naturally did not cherish himself like the ancient monks, but planned to weaken it, reduce its performance, delete its functions, and finally take out a communication headband that could also be used by ordinary people.

At that time, even ordinary people can share what they imagine in their minds with others through psionic wave communication, without relying on their strong drawing ability, text expression ability, video production ability, etc., in order to indirectly share their imagination with others.

Speaking of which, it's going to be a huge industry.

As soon as this communication headband comes out, all telephones, mobile phones, computers, and networks will be eliminated.

What's more, this communication tool can resist the environment of high-energy particle activity and high-energy particle concentration, in other words, even after the explosion of geomagnetic core energy, it can still be used normally, and will not be directly eliminated like the communication technology based on electronic technology now.

After the test was successful, Yang Chen didn't care, took out the wireless communication module that had been hanging around his neck and disguised as a pendant, and took out the rice headset in his ears and the throat microphone under his throat.

Not only that, but Yang Chen had also turned on the automatic recording function of the refining furnace before, which could record the entire process of refining the cultivator and use it to analyze the gains and losses afterwards.

In addition, this record can be used as a standard for the furnace automatics process. As long as it is imported into the refining furnace automatic refining module, the previously recorded magic weapon refining can be carried out automatically without manual labor.

At the very least, it can be done automatically as long as it doesn't have to be done by a human being. It's going to save a lot of things.

What's more convenient is that this record can be deleted, added, and modified at will, and multiple refining processes can be combined into a perfect refining process, of course, it must be the refining of the same magic weapon, otherwise it will definitely make the refining furnace go wrong, and it may not even explode the refining furnace.

This time, Yang Chen intends to use it as a basis, and then integrate the refining of the monkey version of the communication headband with the reduction function to form a standard process, which will be used for mass production of the monkey version of the communication headband in the future.

After doing all this, Yang Chen began the refining weapon that he really had to invest a lot of energy into: the refining of the natal calculator.
