Under the protection of the two sacrifices, Ye Kai walked along this energy channel for about an hour, the sacrifice in front of him suddenly stopped, and then pinched with both hands, there was a burst of energy fluctuations in front of the energy channel, and an energy door appeared, and the priest in front turned around and made a gesture of please, letting Ye Kai go out first.

With a face full of doubts, Ye Kai walked out of this door of energy, and his eyes lit up, this is simply the legendary fairy world on the earth, full of unknown exotic flowers and plants, all kinds of spiritual fruits can be seen everywhere, towering mountains in the distance, waterfalls and flowing clouds, the top of the mountains, the palaces are dotted, strange birds and beasts are flying and moving, a scene of a happy land.

"Distinguished guest, this is the Void Fortress of our Demon Realm, which is equivalent to the Spiritual Mountain of the Heavenly Court and Buddha Realm of the Immortal Realm!" An elf priest on the side saw Ye Kai's puzzled eyes and quickly explained.

Ye Kai secretly said in his heart, he didn't expect that the Demon Realm also had a holy land like the Immortal Realm, it was really not simple, and at the same time, he said, "There are two Lao!"

The elf who originally led the way in front said: "Distinguished guest, although this is already the Void Demon Castle, there is still a certain distance to the Demon Emperor's palace, please take this flying carpet up, you can not only enjoy the scenery, but also save time." As he spoke, the elven priest had already sacrificed a flying carpet about five or six meters long and wide, in mid-air.

Ye Kai nodded slightly, and then jumped up, this flying carpet is exactly the same as the flying carpet in those fairy tales on the earth, sitting on it is like sitting on flat ground, very stable.

After the elf sacrifice waited for Ye Kai to stabilize, he controlled the flying carpet and slowly walked forward, the speed was neither fast nor slow, it was estimated that he also wanted Ye Kai to slowly enjoy the scenery in this magic castle, and the rare birds and beasts that were constantly flying over the side in flight did not disturb the people on the flying carpet, obviously those birds basically knew the people on the flying carpet.

In less than half a day, the flying carpet descended smoothly in front of a palace, and immediately two elven priests greeted him.

"Distinguished guest, the Demon Emperor is already waiting in the main hall, please come with me. One of the elven priests saluted Ye Kai and said.

If you come, you will be safe, since you are here, Ye Kai will not ask much, anyway, wait to see the demon queen later, all doubts will be solved, under Ye Kai's signal, the two elf sacrifices took Ye Kai one after the other and walked towards a huge palace in front of him.

The palace is built in a huge and magnificent way, and the interior decoration is full of simple vicissitudes, flying dragons and carvings and phoenixes everywhere, showing the imperial prestige.

At this moment, the Chiyou Demon received all the imperial power, sitting in the main hall, there was a wooden table and wooden chairs in front of the Chiyou Demon Emperor, and the table was full of various spirit fruits, obviously this place should be specially reserved for Ye Kai.

The Chiyou Demon Emperor was originally more than three meters tall, but in order not to make Ye Kai feel pressured, he deliberately used his supernatural powers to make himself an ordinary person who was about the same height as Ye Kai, and the aura on his body was restrained, and he couldn't tell that he was a high-ranking emperor at all.

One of the elven priests took Ye Kai to the main hall, stood a few meters away from the Demon Emperor of Chiyou and saluted: "Demon Emperor, the distinguished guest has been brought!"

Ye Kai also hurriedly followed and saluted: "In the next Ye Kai, meet the Demon Emperor, I don't know what the Demon Emperor summoned here!"

"Guest, please sit down first, drink a glass of wine from my Demon Realm and talk slowly!" said the Demon Emperor of Chiyou, his voice sounding no different from ordinary people, obviously he also deliberately put away his usual majesty.

The elven priest saluted and retired after Ye Kai sat down, although Ye Kai was only about two or three meters away from the Chiyou Demon Emperor, but no matter how focused he was, he couldn't see the face of the Chiyou Demon Emperor clearly, obviously this was a doppelganger of the Demon Emperor.

"Distinguished guest, you don't have to guess anything, I have no malice in inviting you here, although I am a doppelganger, but there are very few people who can really see my doppelganger, so you don't need to be polite, I invite you to come to know something. The Demon Emperor saw Ye Kai looking at him with puzzled eyes and explained.

Ye Kai put away his puzzled eyes and asked unnaturally, "Demon Emperor, can you detect that I have the Holy Relic of the Heavenly Demon Emperor on my body?"

"Don't get me wrong, I invited you here this time, not because of the holy relics of the Heavenly Demon Emperor, I already know that the Heavenly Heavenly Secret was reborn, since you have the fate to get it, it is your fate, this time it is because our Demon Realm Elf Sacrifice Family has a prophecy, it is said that the four worlds will one day face the catastrophe of alien invasion, and they estimate that the time will be more than two hundred years later.

The only hope is in the body of a young man, his origin and future are vague, and even the ancient priests can not use the Heavenly Dao to find out, but one thing is certain, this person can save our four worlds, and that person is you. The Demon Emperor said straight to the point.

"Oh, it turns out that your Demon Realm also knows about this, it seems that the so-called alien invasion is real, the problem is that with my current cultivation, I can't help you at all, even if I cultivate to the emperor level, you can't do anything, I guess it won't work!" Since the other party said so frankly, Ye Kai naturally said fearlessly.

"We can't speculate on how you can help us, but I'm sure you'll be able to help us in the future, so I'm asking you to come over and see if there's anything you need our help with. The Demon Emperor said very politely.

"I want to know what kind of alien race you are talking about, is their combat power stronger than your emperor-level powerhouse? You can destroy a star at will!" Ye Kai said the question that he had been wondering about in his heart.

"When the alien race invaded the Immortal Continent, our Demon Realm and the Demon Realm did not participate because of the distance, but as far as I know, the strength of the alien race surpassed our cognition, and the emperor alone fell more than a dozen in that battle.

Do you know that being able to grow to the level of the emperor has long surpassed the six reincarnations, and in the face of the alien race, so many emperors have fallen, you can imagine how powerful the alien race is, and the few emperors who survived that war were also seriously injured, and then slowly recovered after hundreds of thousands of years of recuperation.

They didn't want to mention it, so outsiders didn't know what the alien race was like and what happened on the battlefield in the first place. "Chiyou Demon Emperor Road.

"According to what you said, there are few people who really know about that battle, as the so-called knowing oneself and knowing the other side can win, they don't say this, let us prepare in the future. Ye Kai sighed and said.

"I think they already have a hunch, the alien race should already be coming in the direction of our four realms, according to the estimation of our elven clan sacrifice, it will be two hundred years to reach our four realms, I believe that the emperors of the other three realms should be prepared. The Demon Emperor was silent for a moment and said.

"Hey, you are all high emperors, even if the war happens, the first to suffer are ordinary people, I can't imagine any other people who are stronger than you emperors, unless God sent an angel army, but since God created everything in this world, it is impossible to do this!" Ye Kai said with a melancholy face.

"Oh, are the four realms known to be the god realm?" The Chiyou Demon Emperor was obviously attracted by the topic that Ye Kai had inadvertently mentioned just now.

"It's really not complacent, according to what I have learned, the Four Realms should be a galaxy in this universe, I am from the distant solar system, and I also came to your realm by accident.

There are many legends about your four worlds in our place, and there are also legends of God's creation of the world.

I even met a few people on a low-level star in the fairy world, they insisted that God created this world, they didn't believe in immortals, Buddha, or demon gods, they believed in gods.

So I'm more sure that there must be a divine realm, but I can be sure that the alien race was not sent by God to destroy this starry sky. After Ye Kai thought about it, he still told the truth.

"Sure enough, as the elven clan priest said, he uses the Extreme Heavenly Dao, and he can't see your origin and future, you are originally from outside our four worlds, it seems that we are sitting in a well and watching the sky, thinking that we are the masters here, so can you tell me what your world is like?"

Ye Kai had no choice but to simply talk about everything on the earth, and the information about the universe and the starry sky was basically what was seen in the book and on the Internet.

After listening to Ye Kai's story, the Demon Emperor was shocked again, he couldn't imagine that there was such a planet in the distant universe, where there lived such a group of human beings with a lifespan of only a hundred years, but although these human beings had a short lifespan, their creativity was very amazing, and more importantly, Ye Kai was actually only over a hundred years old, and he had only cultivated for so many decades to reach such a terrifying level, no wonder the elves said that he would be the one who saved the four worlds.

The Demon Emperor of Chiyou is now even more convinced that Ye Kai can save the four worlds, and at the same time, he is also very interested in Ye Kai's special mention of the legend about Chiyou in the book on the earth, although Chiyou was defeated by the Yellow Emperor in the battle, but later generations respected him as the god of war, which is very in line with the characteristics of their demon world.

The Houqing Demon Emperor and the Chiyou Demon Emperor were originally known for their battles in the four worlds, and the two of them went from obscurity to becoming the emperor of the Demon Realm, and they relied on their strong fighting style to conquer other people who resisted.

"It seems that your planet called the Earth must have been there a long time ago by people from our Four Realms Pioneer Group, maybe because they found that there was no aura in your place and gave up, and it is precisely because of that that that they will leave behind all kinds of legends of our four worlds, and at the same time, the legends of God's creation of the world have also been preserved, if my guess is right, maybe our four worlds in your galaxy will not be too far away. The Demon Emperor also calmly analyzed the myths and stories on the earth for Ye Kai.
