Tian Xu handed the mirage bead he had just gotten to Medicine King Dou, and threw the scallop in his hand back into the water that had regained his freedom, and asked, "Sister Dou, won't the mirage that has not undergone discoloration affect its function?"

"Of course it will have an impact, but when it's time to use it, I'll ask you to process it. If you really don't have time, Yin Yang Ding can also do this job. Medicine King Dou said, "With these mirages, the possibility of the recovery of the Hundred Grass Whip is much greater." ”

Seeing Yao Wang Dou's relieved expression, Tian Xu's mood also improved a lot.

He immediately thought of another question, and asked Medicine King Dou, "Sister Dou, this mirage is obviously produced from these mutated scallops, why is it called mirage?

Medicine King Dou said, "I knew you would ask this question. Speaking of which, the mirage and these scallops are actually the same kind, and the mirage is also a giant sea mussel. It's just that the number of mirages is scarce, and they are usually dormant in the deep sea, and it is rare for the world to see them. I only heard the Emperor mention it twice, and I don't know the details. ”

Tian Xu said: "Legend in the secular world says that a mirage is formed by a mirage, and after people see a mirage, some people go to look for it, but they can never reach it." Some people disappeared and never returned. Scientists in the secular world have offered various explanations for this phenomenon, but none of them have been able to justify themselves. As for what the legendary mirage really looks like, there is very little clear statement, and even in the legends, it is generally unknown. But when I was a child, I heard my mother say that it was indeed recorded in ancient books that mirage was a kind of big shell. My mother, who was well-read and a well-known writer and historian in the secular world, should not be wrong when she said that it was written in ancient books. ”

At this time, Shennong Hoe, who was as tired as Tian Xu, suddenly interjected and said: "When I was fighting with the Great Emperor back then, I once saw a mirage, that is, the appearance of a big shell, and the size is not particularly large, I don't know if it has changed, but it is certain that the mirage is a clever spiritual cultivator, and its strength can reach a relatively strong point." It's just that I haven't seen a mirage fight, so I don't know the details. ”

Medicine King Dou said: "The cultivation method of mirages is quite special, it is said that they do not collect spiritual energy for cultivation by themselves, but control other creatures to collect spiritual energy and other energy for it through their powerful spiritual power. Mirage likes to be clean, does not eat by itself, does not touch dirt, and basically does not produce pearls in its body. However, the shellfish they control will produce mirages under the influence of their spiritual powers. The presence of mirages favors the mirage's control over these shellfish. These scallops are supposed to be the subordinates controlled by the mirage, and the mirage is also attacking you to protect its subordinates. ”

This statement is reasonable, and Tian Xu has no choice but to believe in the statements of Yao Wang Dou and Shennong Hoe.

Tian Xu put aside the mirage for the time being, he had more important things to do. These scallops and mirages communicate through bioelectricity and electromagnetic waves, and transmit energy to attack from a distance, he is going to spend some time to understand the problem of bioelectricity and electromagnetic waves, and at the same time, he also needs to understand the bioelectric field he emits, otherwise his actions will have no privacy in front of cultivators who have mastered the laws of bioelectric fields, which is unacceptable in any way.

Tian Xu asked Yao Wang Dou, Shennong Hoe and Ziyan to rest by themselves, and called out the Yin Yang Ding that was still in his body, and he himself came to the top of the scallop lake, where he was suspended and pondered the matter of bioelectricity alone. The lake is less than ten meters deep, and his field can cover the scallops in the water, feeling the properties of the bioelectric field they compose.

It is said that human beings are not born with the ability to sense weak bioelectricity, and no matter how hard Tian Xu tries, he can't feel the existence of this weak energy. Fortunately, he has a strong spiritual realm, and with the spiritual realm, he is still able to do this.

While feeling the bioelectric field of the scallops, Tian Xu also tried to feel the bioelectric field emitted by his own body. I don't know if I don't compare, it turns out that the electric field emitted by his own body is much stronger than that of scallops, and it is also much more complicated. He speculated that this might have something to do with the fact that he, as a higher animal, was far more neurologically active than lower mollusks such as scallops. In order to make it more convenient to use the spiritual realm, Tian Xu summoned Dan Ling from the outside world as well, and let Medicine King Dou float in the water by himself. The reduced volume target of the Medicine King Dou was very small, and it was inconspicuous in this boundless deep sea.

Tian Xu found that in the air, the propagation distance of the bioelectric field is much farther than in seawater, which may be related to the fact that seawater can be used as a conductor for grounding and can play a shielding role.

Yaowang Dou's shielding effect on electric fields and electromagnetic waves is more powerful than that of seawater, and this space is simply a pure land of electromagnetic waves, and there is no messy electromagnetic interference from the outside world at all, which is a good place to study this aspect of the problem.

For Tian Xu, who has a spiritual realm, it is not a difficult thing to feel the bioelectric field, he quickly figured out the bioelectric characteristics of himself and the scallops, and then explored all the animals in the Medicine King Dou such as Purple Smoke, Giant Turkey, Yepug, Dragon Sparrow, etc., followed by plants. The bioelectric field of plants is much weaker than that of animals, but it still exists, and after careful observation in his spiritual realm, he finally figured out the bioelectric field of plants. The four artifacts are neither animals nor plants, but their mental fluctuations also have obvious electric field activity, but the parameters and characteristics of the electric field are different from those of animals and plants.

Tian Xu tried to use the domain to hide his bioelectric field, but it didn't seem too difficult. He then used the field to simulate the electric fields of other animals or people, which was a bit more difficult, but he managed to do it.

Later, Tian Xu could already add the bioelectric field signal to his and Dan Ling's stealth technique through a compensation method similar to stealth technique, which improved the concealment of his stealth technique a lot.

Eventually, he began to grope for electromagnetic waves of a specific wavelength like a mirage or a swarm of scallops, as well as the long-range energy delivery that the mirage used to attack him, but encountered great difficulty.

Tian Xu didn't have a ready-made electromagnetic signal to refer to, so he could only do it based on an exchange between the scallop group and the mirage of the domain memory, as well as the kind of summoning signal sent by the mirage. But at that time, he didn't know much about this electromagnetic wave, and he was missing a lot of important information in his memory, and he couldn't decipher the content of the communication signal, so he couldn't grasp it at all. And since those scallops entered the Medicine King Bucket, they only sent a long-wave signal after Ziyan killed a scallop and caused their group attack, and then there was silence, all of them quietly eating the shark fragments that Tian Xu brought to them.

Tian Xu recalled the timing of the scallop swarm's communication signal twice, the first time seemed to be after the successful hunt of sharks, and the second time was after the failed attack on Ziyan in the Medicine King Bucket. "Is it that every time they attack, they emit electromagnetic signals?" Tian Xu thought secretly.

He was above the scallop pool, unleashing his bioelectric field, and the scallop colony sensed his presence and jumped up to attack him. When Tian Xu hid his bioelectric field, the scallop group found nothing after a group of demons danced wildly, and gradually calmed down, and after a few minutes, the combined bioelectric field of the scallop group fluctuated for a while, and then a long-wave signal was sent out, which was easily intercepted by Tian Xu.

Tian Xu felt this electromagnetic signal in detail, as well as the fluctuations of the bioelectric field when the scallop group emitted the electromagnetic signal, and found that this signal was emitted through the reciprocating vibration of the bioelectric field. The scallop group has a relatively large bioelectric field coverage, they occupy an area of tens of meters in a square circle of the population volume, forming a composite bioelectric field, the potential of this electric field fluctuates back and forth, forming a resonance effect like a tide, which can emit electromagnetic waves at the same frequency.

However, the energy of the electromagnetic waves emitted in this way is very low, and it will not travel far before it will decay to a degree that it is difficult to feel. He used his domain and bioelectric field to simulate similar electromagnetic waves, and the energy instilled into them was so low that no matter how hard he tried, it was difficult to increase it. It is very difficult for this electromagnetic wave to transmit information to distant places, let alone use it like a mirage for long-range attacks.

Tian Xu repeatedly stimulated the scallop group to emit electromagnetic waves, and he could clearly feel that the electromagnetic waves emitted by the scallop group were weaker and weaker each time, and after four or five consecutive times, they were weak enough to be close to the level emitted by themselves.

Tian Xu got a giant jumping rabbit and threw it to the scallop group, and after these guys had a full meal, they emitted electromagnetic waves again. After eating, I really had strength, and the electromagnetic waves emitted became stronger again.

This time, Tian Xu, who was engrossed, clearly felt that the frequency of the electromagnetic waves emitted by the scallop group was significantly different from the previous few times when there was no harvest, and the frequency was nearly doubled. In addition to this, this electromagnetic wave is a little different, in addition to the long-wave oscillation, this wave also contains another lower frequency oscillation, which is more than ten times the frequency of the basic long-wave frequency. In this low-frequency oscillation, which is contained in the basic long wave, there is much more powerful energy, and this transmission is directional!

In the process of transmission, the loss of this ultra-long wave will be very small, and it can be transmitted to a long distance. If it is a directional transfer, it is no problem to use it for long-distance energy transfer.

Tian Xu called the Medicine King Dou and asked, "Sister Dou, just now the scallop group sent out an energy transfer, can the energy it emit be transmitted outside?"

Medicine King Dou pursed his lips disdainfully and said, "Who am I?" But the head of the four great artifacts under the Great Emperor, like these little things, still want to transmit signals to the outside, not to mention that the energy they emit is only so little. ”
