Another sleepless night passed, the communication equipment still failed to make it, the formation has been successfully tested, but the problem of insufficient energy, if it is in a very short distance, there is no problem, but if you want ultra-long-distance communication, and the current situation can not have any satellite base station or anything support, so this emission source, there must be enough energy.

Although it is said that it can be used by gathering energy through the Mithril Array, it is just that if you want to gather enough energy, this communication equipment must be very large, and it is initially speculated that if you want to communicate in tens of thousands of miles, the energy convergence array alone needs to be three or five meters in diameter.

It is obviously impossible for a few apprentices to carry such a large thing all the time, even if they join the size Ruyi array and shrink the thing, but after shrinking, the energy gathering amplitude will also be reduced.

Of course, you can also make things bigger when you use them, and put things away when you don't use them, although it is troublesome, but it can be overcome, but the cost of making such a large and energy-converging Mithril formation is too high, and it takes at least 100 kilograms of Mithril to make such a communicator, and now it takes more than a month to refine ten kilograms of Mithril.

And at present, it is not possible to expand production capacity at will, and some time ago I also tried to increase production, but when the furnace was opened, it was warned by a lightning disaster, so the production increase plan was suspended, maybe only a small amount of production at this stage will not destroy the balance of the law, and a large amount of production may destroy the balance of the existing laws in this world.

"Apprentices, do you know what is in this world that can continuously emit aura energy from the outside?" When they got together for breakfast, Li Yunfei asked his apprentices.

"Well, the Innate Spirit Treasure can form its own cycle, and it can continuously provide spiritual energy!"

"I know that the Buddha Treasure Relic can also provide a lot of aura."

"Dragon Ball is OK too!"

"Jin Dan is okay too!"

A few apprentices, you and I answered one by one, but the few things mentioned could not be used as the energy source of the communication device.

"Isn't there any spirit stone or anything like that, which can produce a steady stream of spiritual energy?"

"There is such a magical stone, it shouldn't have been refined a long time ago, right?" Bajie said something else, that Sun Monkey is going to beat people again, Bajie is indeed hiding in Tibet, these two guys are indeed very strange, they add up to more than long live, but they still like to fight like children.

"You two don't make trouble, it's important to hurry up and finish your meal!" Li Yunfei said with a headache, the two apprentices were obedient, and when they saw Li Yunfei speak, they stopped playing and continued to eat the breakfast that was not sumptuous, but very large.

……

“…… Master has been in bad spirits lately, but he misses the White Lady? Seeing Li Yunfei's listless appearance, Bajie did come to Li Yunfei and asked in a low voice.

"Of course I think so, but this bad spirit is due to some minor troubles in the study of a communication device." Li Yunfei didn't hide anything, saying that he didn't want the white lady to be fake.

Although the White Lady is not her first love, she is the first woman in her life, and she is still a charming and tender woman.

"Master, why do you say that the heavenly court forbade male fairies and female fairies to fall in love?"

"You haven't known about it for so long in Heavenly Court, and how do I know if I haven't been to Heavenly Court...... However, there must be a reason for the existence of such a rule! Li Yunfei also had some doubts about this.

It stands to reason that before cultivating the innate one, abstinence is indeed of great benefit to the cultivation, but after reaching the congenital, as long as it is not overindulgent, it really doesn't matter, and it has become an immortal, do you still need to be so strict? If you steal a love, you will be demoted? It doesn't seem to be, for example, the pure yang real person has developed a relationship with a mortal woman in the lower realm many times, patted his ass and went to the sky after he was done, and he didn't have any shit, he still became his immortal, and he enjoyed extremely high treatment. In this way, those little gods and fairies, that is, those who have no ability to bully them, are useless to the truly powerful immortals. It seems that the rules of Buddhism are like this, and I don't know how much robbery I have committed for a long time, but the gods and Buddhas in the sky still politely called the holy monk when they saw it.

“…… I miss Cuilan...... Master, thank you for the Nine Turns Pill! ”

"Don't be so polite, work diligently in the future, and the benefits will naturally be indispensable to you!"

"In fact, when I was a marshal in the heavenly court, my old pig was also a very diligent and honest person, but he drank and misbehaved the little fairy, and after being demoted to the lower realm, he accidentally became a pig demon and became lazy."

"Didn't the Jade Emperor punish you for being a pig demon?"

"Of course not, my old pig was also a cronie of the Jade Emperor back then, but he was just a little fairy after drinking, how could he be punished as a pig demon. The original punishment was only the reincarnation of the Nether Realm, and the reincarnation of the official eunuchs would be great generals in the future. It's just that I don't know where it's wrong.,It was originally my body but someone took the first step to forcibly occupy it.,The old pig has nowhere to store the soul.,Almost lost the soul.,I had to find a pig body nearby to temporarily store the soul.,I didn't expect it to become a pig demon unexpectedly.。 Bajie said a little lonely.

“…… Look away, let him go over the past, and in the future, he will cultivate and retreat from this pig demon body, maybe a little more powerful than before...... But Fairy Chang'e shouldn't be a little fairy! ”

"What Master means by Chang'e, Taiyin Xingjun?"

"Is there any other Chang'e?"

“…… This, in fact, the immortals in the Moon Palace can be called Chang'e...... My old pig was only a fairy in the Moon Palace, but I didn't tease Sun Xingjun, and my old pig is not a fool, where do I dare to tease her old man! ”

"So the envoy of the Moon Palace who came to exchange for the Creation Silver can also be called Chang'e?"

“…… Generally speaking, when the immortals talk about Moon Palace Chang'e, they are still talking about the Taiyin Star Monarch! ”

"That's a mess!"

"It's not a mess, it's like the Buddha and the Buddha, every Buddha can be called the Buddha, in fact, the Buddha and his old man are the ones we often say."

“…… That's right, the knowledge has grown! ”

"It's all taught by the master."

……

The master and apprentice walked and stopped, and it had been more than half a month since they left Che Chi Guo, but this day they encountered a super wide river blocking the way, but it was the Tongtian River that was hundreds of miles wide and arrived.

This time, Li Yunfei didn't have the slightest embarrassment, he directly took out a palm-sized boat from the Ruyi bag, put it into the water, and after reciting a spell, the size of the Ruyi formation in the small boat was suddenly activated, and in a blink of an eye, it became a big boat ten meters long and four meters wide.

The structure of this ship is extremely simple, it is to add a few simple Mithril formations to a wooden boat, usually this magic ship is put away, only the size of a palm, and when you want to use it, you only need to chant a spell to activate the size of the Ruyi array on the magic boat to become a big ship. As a formation expert, of course, several other formations have been added to the magic ship, such as formations that can drive the boat forward and strengthen the hull of the ship.

“…… Apprentices, get on board! Seeing that several disciples were in a daze, Li Yunfei reminded him.

"Master, old man, when did you get such a good baby?"

"What kind of treasure is this thing, it's just a small boat, but it was made when I was a guest in the Black Water River God Mansion."

"It turns out that the master is in the River God Mansion, and he is not just having fun with that little lady."

"You think everyone is like you idiot, you know how to eat, drink and have fun when you go to Gao Laozhuang!"
