When he was on the earth before, Chen Ping hadn't felt it, but now compared with the demon world, the aura on the earth can almost be so thin that it is negligible!

Chen Ping had just come to that place in the demon world, and the aura concentration should have been about five times that of the earth, and then Chen Ping had gone all the way here, and the aura concentration had reached about seven times that of the earth!

If the aura concentration can continue to increase, then even if it reaches ten or twenty times, it is possible!

Although the concentration of aura does not represent the speed of cultivation, there is definitely a relationship between the two!

If you can really have ten times the concentration of aura on earth, then everyone's cultivation speed will be twice that of earth!

If it was twenty times the concentration of spiritual energy, then the cultivation speed would be three times!

And so on, the higher the concentration of aura, the faster the cultivation speed will be!

Therefore, in such a place, Chen Ping's cultivation speed would naturally increase.

He now has no medicinal power to rely on, and if he continues to cultivate, he can only try his best to increase his cultivation speed.

With the concentration of aura in the demon world, Chen Ping's cultivation speed is not slow, and with the fact that there are a lot of medicinal materials in the demon world, he may be able to find an eighth-grade or even ninth-grade medicinal material suitable for improving his strength!

However, there are only a few medicinal materials that can be used to improve strength, and most of the medicinal materials need to be coordinated to refine them into pills to improve their strength.

However, the number of medicinal materials above the seventh grade is very small, and there are very few prescriptions for the elixir refined from the medicinal materials above the seventh grade, so under normal circumstances, the vast majority of the medicinal materials below the seventh grade have an effect, and they can be refined into pills with each other to improve their strength.

However, if there are more than seven grades, they can only be used alone.

Therefore, those medicinal materials that can improve their strength above the seventh grade are extremely precious existences.

Among the medicinal materials that Chen Ping obtained in the demon world, only a few of them can improve their strength, and they can be used on Chen Ping's own body, but the gains outweigh the losses, and it is better to leave them to others to improve more.

As for himself, he also needs at least eight grades, and maybe even nine grades of medicinal materials to be able to greatly improve his strength.

But this kind of thing can only depend on luck.

However, what made Chen Ping a little strange was that although there were a lot of Chinese medicinal materials in this demon world, they were not as Xiaobai said, there were eight grades and nine grades everywhere, and even the transformed medicinal materials had a lot of appearances.

Thinking of Xiao Bai, Chen Ping suddenly patted his head, and a little sweat appeared on his face, and he hurriedly released Xiao Bai from the space ring.

When I was in Miao Village before, almost everyone's attention had been attracted by Chen Ping, Miao Ling'er and the dozen or so clan elders all paid attention to Chen Ping, no one noticed Xiaobai, and no one even noticed when Xiaobai disappeared.

It was Chen Ping who found an opportunity halfway through and let Xiaobai return to the space ring before bringing him into the demon world.

Although the space gate of the demon world can only accommodate Chen Ping to enter alone, the space ring can naturally be brought in, that is to say, except for Xiaobai, Chen Ping may not be able to bring anyone else.

After coming out of the space ring, Xiao Bai almost habitually glanced at Chen Ping, but then sniffed, then looked around in surprise, and said in surprise: "What kind of place is this?

Chen Ping was stunned for a moment, and looked at Xiaobai in front of him with a stunned face, with an inexplicable expression: "Isn't it the Demon Realm?"

Xiaobai scratched his head, looked around, and then stuck out his tongue: "It's me who saw it wrong, this is the demon world, but it should be the periphery of the demon world, I have never been here!"

Chen Ping's eyes flashed slightly, and then asked, "What do you mean by the periphery?" Do you know more about the demon world, give me a good introduction?"

Xiao Bai smiled, then pointed to the mountain range in the distance, and said with a smile, "Do you see that mountain range?"

Chen Ping nodded slightly.

Xiao Bai said with a smile: "That mountain range is the dividing line between inside and outside the demon world! Although I don't know how that mountain range appeared, but that mountain range is definitely an existence that you can't even think of! That mountain range is tens of thousands of meters high, day after day, towering into the clouds, and after the height reaches more than 10,000 meters, there will be coercion, except for the innate above, no person or demon beast can cross that mountain range!"

"And that mountain range stretched for tens of thousands of miles, dividing the entire demon world into two layers, inside and outside. ”

Speaking of this, Xiaobai directly squatted down and drew on the ground.

It's just two simple circles, one large and one small, and the small circle is in the center of the big circle.

"See, this big circle is the entire Demon Realm Continent, and the small circle in the middle is the inner perimeter of the Demon Realm, that is, the place I have been to before! There, it is the core of the Demon Realm! As for the periphery of this Demon Realm, although the area is larger, there are very few innate demon beasts crossing the mountain range to the periphery of the Demon Realm!"

"Well, there are actually three reasons, one is because the concentration of aura in the periphery of the demon world is only about half of the inner periphery of the demon realm, and the closer to the edge, the lower the aura concentration, here, it should be regarded as the periphery of the periphery!"

"Second, it is the circular mountain range, oh, in the mouth of the demon beast of the demon world, it is the Ten Thousand Realms Mountain, the Ten Thousand Realms Mountain is very special, very magical! The demon beasts on the periphery, if they reach the peak of the innate five layers, and have not broken through the innate above, it will be difficult to break through in the periphery, after all, the aura concentration is still a little insufficient, so they can only choose to break through the Ten Thousand Realms Mountain! As long as they have passed the Ten Thousand Realms Mountain and can survive under the pressure of the Ten Thousand Realms Mountain, they will be able to break through to the innate top!"

"But once you enter the inside of the Ten Thousand Worlds Mountain, it will rarely come back, because from the outside to the inside, it is just a simple coercion, not too strong, but from the inside out, the coercion can even hurt people! Oh no, it hurts the demon! Once the inner demon beast comes to the outside world through the Ten Thousand Worlds Mountain, it will be severely damaged, and even the realm will fall! Directly fall back to the innate level! That is to say, when you return to the periphery, you will turn back into the innate demon beast again, and it is easy to die outside, and the gains outweigh the losses! You have to die in the inner perimeter!"

"As for the third reason, it's outside the Demon Realm Continent!"

As he spoke, Xiao Bai pointed to the outside of the big circle, and then said with a serious face: "It is said, it is just said, I am not sure, because it is just the gossip I heard, outside the Demon Continent, there is the Endless Sea, and on the Endless Sea, there is no existence of the slightest spiritual energy at all! Moreover, in the Endless Sea, there are endless crises and endless spatial cracks! It is an absolute sea of dead silence, and no creature can survive in the Endless Sea!" Even the sky above the Endless Sea is an infinite space crack, this thing, as long as it is one, it can kill the innate master!

After listening to Xiaobai's explanation, Chen Ping finally had a certain understanding of the Demon Continent.

For the Endless Sea, Chen Ping has no intention of exploring, what he really cares about is this inner and outer periphery!

According to what Xiaobai said, there is a world of difference between the inner and outer periphery, and if you want to enter the inner perimeter, you can only enter the Wanjie Mountain!

This Demon Realm Continent is simple, but Chen Ping didn't despise it, but asked in a deep voice: "Then do you know how big the Demon Realm is?"

Xiao Bai hesitated for a moment, and then said in a deep voice: "I remember that there was a great demon in the God Realm who once said that the Demon Realm Continent has an inner circumference of 30,000 li, a periphery of 70,000 li, and a length and width of 100,000 li!"

Chen Ping's eyes widened suddenly!

The length and width are 100,000 li, even if it is not a regular circle, it is still roughly the same, that is to say, this demon realm continent is close to 2 billion square kilometers!

You must know that the total land area of the entire earth is about 150 million square kilometers, and this demon realm is equivalent to the area of nearly 14 earths!

Chen Ping raised his head abruptly and looked at the surrounding Demon Realm Continent, and his eyes also showed a bit of shock.

However, after a while, Chen Ping also calmed down, and then continued to ask.

In the face of Chen Ping's many questions, Xiaobai doesn't know everything, and can only answer some of them.

In the end, after Chen Ping asked all the questions, he hesitated for a moment, then took out the dagger he had obtained before, and asked in a deep voice: "This dagger was found by me on the body of a demon beast, is there still a human being in this demon world?"

Xiao Bai was also stunned for a moment, then took a closer look at the dagger, and then shook his head: "As far as I know, it seems that there was one thousands of years ago, but I have never seen it, at least within a thousand years, there should be no human beings!"

Chen Ping was stunned for a moment, but he also knew that Xiao Bai would definitely not be able to find the so-called human cave, but Chen Ping still asked a little strangely: "How do you know so much about the demon world?" And you always say that it is said, but who do you communicate with? Demon beast? But when the demon beast sees you, won't it eat you?"

Xiao Bai smiled, and then said: "I said, don't be too shocked! Tell you, within the Ten Thousand Realms Mountain, unlike the periphery, all the demon beasts are scattered and survive on their own! The inner perimeter of the demon realm is a country of demon beasts, a society that belongs to demon beasts! Although this so-called demon beast country is also divided and integrated with your human country, it is also similar to you human beings, and it is also a complete society! I am still a citizen of that country!"

The last news released by Xiaobai was like a huge one, which instantly stunned Chen Ping in shock!

Xiaobai had never seen Chen Ping so shocked and discolored, and he also felt a little funny, and then briefly talked about the so-called demon beast country.

It's been thousands of years since Xiaobai left the demon world, and I'm afraid that the demon beast kingdom has already changed now, but there are some things about the demon beast society, and it shouldn't change.

Listening to Xiaobai's narration, Chen Ping fell silent deeply.

In the past, Chen Ping had always regarded the demon world as a chaotic and primitive world full of brainless demon beasts, but now, everything he knew overturned all of Chen Ping's ideas!

The water in this demon world is very deep!

However, Chen Ping was not anxious, because he knew very well that it was impossible for him to cross the Ten Thousand Realms Mountain and enter the inner periphery of the Demon Realm now, and there was no need to even venture into the inner periphery of the Demon Realm for the time being, so he would simply venture around the periphery now!

With Chen Ping's current strength, even if he encounters an innate fifth-level demon beast, he is not without the strength to fight, at least if he wants to escape, there are few demon beasts that can catch up with him, not to mention that there are also means to hide his breath, Chen Ping can almost be called rampant on the periphery of this demon world!

After all, it was almost impossible for there to be an innate demon beast on the periphery, so there was no need for Chen Ping to continue to be cautious as before.

Chen Ping looked in the direction of Wanjie Mountain, and a faint smile appeared on the corner of his mouth, but in this smile, it was full of cold meaning!

Xiaobai on the side suddenly shuddered, and his gaze at Chen Ping became strange.
