The Great Dream Dao Monarch came over with the Xuanyuan Dao Ancestor in a group, and when he first faced the guardian of the Dawn World, it must have been for everyone to fight side by side. However, when more and more powers come over from the cultivation world and fight all the way to the barbarian world, each will have room to choose an opponent.

The inheritance of the Great Freedom Sect, to put it bluntly, is good at spiritual battles, rather than real face-to-face confrontations. Therefore, after the situation reached a certain level, the people of the Great Freedom Sect disappeared from the frontal battlefield.

This is also the reason why Xuanyuan Dao Ancestor does not know much about the situation of Da Meng Daojun. Of course, no matter which side of the battlefield it is, there will still be some information exchange between each other after all. Although Xuanyuan Dao Ancestor didn't know much about the situation of the Great Dream Daojun, he could still be sure that the other party was at least safe and sound.

"Oh, in this case, if you want to come to Miaomiao and Mumu siblings, you can also feel at ease when you hear this news. After listening to Xuanyuan Dao Ancestor's answer, Ye Zan nodded and said.

"Hehe, you don't have to worry at all, with their ability to be in the Great Freedom Sect, even if they face an opponent who can't be matched, no one can put them in danger. Xuanyuan Dao Ancestor's words, although there was a bit of mockery, but there was really no derogatory meaning.

Although Ye Zan had never seen the Freedom Supreme make a move, he had personally experienced the skills of the Great Dream Daojun. He had not only watched the Great Dream Dao Monarch make a move, but also personally felt the magic of the power of the dream realm when the Great Dream Dao Monarch was in conflict. Therefore, for Xuanyuan Dao Ancestor's words, he naturally understood without explanation.

"Master, is it convenient for you to bring things back with this doppelganger?" After sending Xuanyuan Dao Ancestor out of the hall, Ye Zan stopped again and asked.

Before, the doppelganger sent by Xuanyuan Dao Ancestor to the Shenhua Domain Realm, after explaining the matter of "preaching" to Ye Zan, directly dispersed his mana and disappeared. In other words, the doppelganger got a one-way ticket, and he just went to Yuqing Sect to inform Ye Zan, even if he had completed his mission.

Therefore, at that time, in the face of the doppelganger who only had a one-way ticket, Ye Zan didn't mention anything to bring to Xuanyuan Daozu. Although, before he could mention it, the doppelganger had already disappeared, but even if he did, he would definitely not be able to carry it.

And now, this doppelganger came to find Ye Zan, and he didn't deliberately avoid the Immortal Court, so there was no need to disperse in a hurry like before. Then, as long as this doppelganger will return to the Xuanyuan Dao Ancestor's deity, then it should be no problem to carry some things.

"What, do you have anything to bring to the deity?" Xuanyuan Dao Ancestor's clone naturally immediately understood what Ye Zan meant, but at the same time he was a little curious.

You must know that the battle on the other side of the barbaric world is not something that a cultivator of the Yuan God Realm like Ye Zan can participate in. Since Ye Zan mentioned that he wanted to carry something, he must have felt that that thing was helpful to Xuanyuan Dao Ancestor. However, Ye Zan's own strength was not enough to participate in such a battle, so what would help Xuanyuan Dao Ancestor!

"At the beginning, during the battle in the Netherworld, the disciple used that kind of nuclear bomb, what do you think, Master?" Ye Zan asked with a wicked smile.

"That...... The power is not easy to control!" Xuanyuan Daozu twisted his beard and said, although he was quite tempted by the power of the nuclear bomb, he was also a little embarrassed because of the power.

Nuclear bombs are different from spells, and although the power is indeed terrifying, the problem is that the damage does not distinguish between friend and foe. Therefore, if ordinary people use that nuclear bomb without a detailed understanding of its power, the result is likely to be the same death. And if you are very conservative and use a nuclear bomb from a great distance, will the enemy stand there stupidly, waiting for the nuclear bomb to explode in front of you?

Therefore, in Xuanyuan Daozu's opinion, the nuclear bomb is actually a bit of a chicken rib, and it is not as good as his own spell.

Of course, Xuanyuan Daozu will have such an opinion, mainly because he does not have an auxiliary chip like Ye Zan. Ye Zan, who has an auxiliary chip, has a detailed understanding of the power of the nuclear bomb, and can determine conditions such as the safe range and the effective range through a large number of accurate calculations. Moreover, Ye Zan can also adjust the power of the nuclear bomb according to the specific situation, ensuring that he can cause enough damage to the enemy while ensuring his own safety to the greatest extent.

"Then forget about the nuclear bomb!" Ye Zan was simply speaking, in fact, when talking about nuclear bombs, there was a certain element of joke. What he really wanted Xuanyuan Dao Ancestor to carry was actually something else, so he continued: "Master, when you came here before, the disciple once brought you some communication equipment, and if you think it is not much use in the barbarian world, right?"

At the beginning, after the battle in the Netherworld, when Xuanyuan Daozu went to the Dawn World, Ye Zan brought some communication equipment to Xuanyuan Daozu. He provided those communication equipment so that Xuanyuan Dao Ancestor could maintain good communication with his fellow Daoists when he was engaged with the enemy. In addition, he introduced a lot of people later, such as those Faxiang Dao Monarchs of the Moyi Sect, who could also contact Xuanyuan Dao Ancestor through communication equipment.

However, although Ye Zan expected it was good, after all, he didn't know the situation here at the time. Not to mention anything else, Xuanyuan Dao Ancestor has now arrived in the barbarian world, so after others come to the Dawn World, of course, there is no way to contact them in the first place.

In addition, battles at the level of the Heavenly Supreme often involve spatial means such as domains and divine kingdoms. Ordinary communication equipment, in the face of space barriers, the communication effect will also be greatly limited. Only quantum communication technology can support communication in complex space, so that communication is not blocked by complex space.

"Yes, the means of communication, including the Thousand Miles of Communication, do fail from time to time. Xuanyuan Daozu nodded and said.

Ye Zan's communication tools for Xuanyuan Dao Ancestor were not only the thousands of miles of communication that were popularized in the cultivation world, but also special battlefield communication equipment. However, no matter what kind of communication tool it is, it will also be greatly affected when encountering a complex space environment.

Moreover, even the application of quantum communication technology is limited by problems such as quantum preset decryption, so that the size of the device will be difficult to shrink. During the battle, this side throws out a quantum communication base station first, even if the other side doesn't know what it's for, they know that it must be beneficial to destroy it.

"As for quantum communication technology, Master should know, but due to technical reasons, it is difficult to control the volume. However, after learning about the situation in the savage world just now, I can customize a device that suits your needs according to the actual situation. After listening to Xuanyuan Dao Ancestor's words, Ye Zan followed closely and said.

When Xuanyuan Daozu was in the world of science and technology, although he couldn't come out of the jade card, he could be regarded as watching the human beings in the world of science and technology develop step by step. Therefore, he has heard of some of the technologies used in the technology world, even if he has not really had the opportunity to contact them.

"In this way, the teacher is a little interested. Xuanyuan Dao Ancestor said unceremoniously.

Although, even without the help of communication equipment, the cultivator's side has been fighting the demons outside the world for many years. However, it cannot but be admitted that in the case of coordinated operations, the existence of communication equipment is still very valuable. If nothing else, let's say a group of people are stuck in a maze and have communication devices to connect with each other, it is definitely better than not knowing anything about each other.

Even at the level of the Heavenly Supreme, or even at the level of the True Immortal, there is inevitably a need to be connected to each other. What do I do, how do you cooperate, and shout directly in the face of the enemy, it will definitely not have a good effect. Moreover, communicating with divine consciousness may not be able to avoid some of the enemy's interference methods, after all, everyone uses extraordinary strength, and the different laws are ultimately similar in nature.

And the communication equipment of the technological world was invented without extraordinary laws. Although, it uses the basic laws that all otherworlds have, the basic ones are often the most neglected. The people of those transcendent worlds have devoted their minds to the laws of developing transcendent powers, and few people will pay attention to those basic ordinary things. As a result, the societies of those otherworldly worlds are much behind the technological world in terms of basic laws.

This backwardness is not something that anyone can catch up with immediately after a sudden inspiration.

Therefore, at least in this war, the means of the technological world brought by Ye Zan will still be very effective for a certain period of time.

"When I asked the master for advice just now, the disciple had already arranged for the manufacture of the equipment, and it should be about the same by now. Since Master finds it useful, then you might as well go over with your disciple to have a look, and let your disciple introduce the specific conditions of use. Seeing that Xuanyuan Daozu was interested, Ye Zan suddenly looked a little proud, and then led Xuanyuan Daozu towards the factory.

In the industrial area of the war fortress, a batch of communication equipment using quantum communication technology has been manufactured and placed in an open field. Those communication equipment are not only headphones, microphones and other things in people's common sense, but also some large and small pyramid-shaped communication base stations.

On the battlefield of the savage world, due to the complex problem of spatial barrier, the communication problem that really needs to be solved the most is how to solve the last step of signal propagation. If the quantum communication technology is directly applied to the personal equipment of the thousands of miles. It will be like a walkie-talkie that matches the frequency band, which can only communicate between these devices preset, and it is difficult for latecomers to join in.

In response to this problem, Ye Zan customized such a batch of devices that use quantum communication technology. The Teleportation or War Communicator is still a device that uses a normal signal, but it is paired with a miniature quantum communication relay. This relay, which is responsible for contacting ordinary signals, converts them into quantum communication signals, and transmits them to quantum communication base stations. The base station receives the signal, and then transfers the signal to other relays that need to be connected, and then from the relays to the ordinary signal.

The principle is probably the same principle, and the actual technology will of course be more complicated, but simply put, it is to use such a relay to solve the propagation of the last step of the signal. Since the relay is only responsible for "one set" of communication terminal equipment, it can also be compressed to the greatest extent in terms of volume. When carried by individuals, this transmitter is probably like a relatively large watch, which is basically not easy to be damaged by the enemy.

Of course, this set of battlefield communication systems with quantum communication technology still requires a quantum communication base station as the center. However, this quantum communication base station does not need to be put on the battlefield, and it does not even need to be taken to the savage world. Ye Zan could add a special quantum communication base station here in the war fortress to be responsible for the communication problems on the battlefield.

"Master, what do you think of this method?" Ye Zan turned to Xuanyuan Dao Ancestor next to him after introducing those equipment.

"Well, that's not bad, even if you add a communication terminal in the future, you just need a set of preset personal terminals. "Xuanyuan Dao Ancestor used the vocabulary of the scientific and technological world quite freely.

"Then, back to the question before the disciple, Master, can you bring these things back?" Ye Zan asked back to the original question.

No matter how much Ye Zan compresses the volume of the equipment here, one set or two sets may not be nothing, but ten sets of 100 sets is a lot of them. However, he can use the Qiankun Ring, even if he uses a few more Qiankun Rings, he can always make these things easy to carry. However, no matter how easy it is to carry, someone has to bring it over and bring it to the Xuanyuan Dao Ancestor Buddha.

"Don't worry, as a teacher, you don't need to avoid people's eyes and ears this time, so you naturally don't need to be in a hurry to disperse the clone. Since there are these things to bring over, then it is better to run for the doppelganger of the teacher. "Xuanyuan Dao Ancestor, even if he originally wanted to disperse the clone on the spot, he would not have done that at this time, after all, these communication devices are still relatively valuable to the battlefield over there.

So, this doppelganger of Xuanyuan Dao Ancestor didn't use Ye Zan to make the Qiankun ring, and directly used a spell in his sleeve to put away all the equipment in the open space.

"The nuclear bomb you mentioned before, if there are ready-made ones, bring a few for the teacher. "After receiving those communication equipment, Xuanyuan Daozu still decided to ask Ye Zan for a few nuclear bombs. Although, as I said before, without the help of auxiliary chips, there will be such and such problems when using nuclear bombs, but it is not completely meaningless to prepare a few in your hands.

"Master, otherwise, I'll prepare a program for you to use a nuclear bomb in a thousand miles of divine transmission. When the time comes, if you really need to use a nuclear bomb, you can use the program in this Thousand Miles of Divine Transmission to have a judgment on the nuclear bomb to be used. Ye Zan didn't want the master, who had finally been resurrected, to overturn because of the improper use of nuclear bombs, so he still tried his best to think of a solution.
