However, the aliens don't know when they came to the earth, and they have built many secret realms in order to refine all the spiritual energy on the earth into golden pills. Then the aliens withdrew for some reason, and waited for hundreds or even thousands of years to come and take away the refined gold pill. ”

"But the creatures on our earth that have their own spiritual energy have suffered, and they can't get out if they accidentally strayed into the secret realm. Herbivorous animals can barely survive in the secret realm. Carnivorous animals are different, this secret realm is not big, and the small animals in it are limited, even if they can continue to reproduce, it will not take a few decades or hundreds of years to all be starved to death. ”

"And the creatures with aura in the wild began to become less and less, and with the drastic reduction of aura between heaven and earth, the environment in the wild is even more unsuitable for them to survive. They will constantly re-search for habitats, which greatly increases the probability of straying into secret realms. In this cycle, to this day, in the wild, not a single creature with aura can be seen. ”

"Well, the analysis makes a lot of sense. Zhu Yan nodded at Wu Yaoxia.

"Theoretically, the probability of encountering a vicious beast in the new secret realm in the future should not be large. Yang Xingchen said: "A creature like Xuanwu, who is like a turtle and is also a vegetarian, can live for so long and not die." Fierce beasts like tigers, lions, and wolves have long since starved to death in the secret realm. ”

"That's not necessarily, maybe you will change to a vegetarian diet if you don't have animals to eat!Vegetarian can live longer~" Ding Lingling disagreed with Yang Xingchen's point of view and retorted.

"This time you have a point. Wu Yaoxia said.

"Then you mean that what I said before is unreasonable!?huh?" Ding Lingling pretended to be vicious, looked at Wu Yaoxia and said.

"I said something wrong, I want to say that Sister Lingling makes sense every time!" Everyone knows that Wu Yaoxia said something against his will again.

"By the way, speaking of the secret realm, where will we explore next time?" Wu Yaoxia forcibly changed the topic and avoided a catastrophe.

"Didn't you say that you would go to that place in the Peach Blossom Spring! Wu Yaoxia thought that he could avoid it, but in fact he didn't, and accepted Ding Lingling's eyes again.

"I searched online for a long time and couldn't find a specific location. Yang Xingchen said.

"Me too, there are a few suspicious locations, but they don't fit the description in the Peach Blossom Spring, it's simply that the descendants claim to be that paradise in order to rub the hot spot. Zhu Yan also said.

"Ah, isn't that why you can't go?" Ding Lingling was a little disappointed after hearing this, and she still had a little expectation before.

"As for the location of the secret realm, I also found out some last night. Wu Yaoxia secretly glanced at Yang Xingchen as he spoke, and found that Yang Xingchen was looking at him with a wicked smile, Wu Yaoxia hurriedly turned his head to look away.

"Where are you?" Ding Lingling's interest came up again, and she hurriedly asked.

"Do you know Guiguzi?" Wu Yaoxia asked everyone.

"I know that a famous figure in the Warring States Period, a famous strategist, the originator of the Zongheng family, and a master of the art of war! He was called the 'Conspiracy Sage'! He hid himself in the world, put the world in a chess game, held black in his left hand and white in his right hand, and entertained himself. Disciples who come and go will decide the survival of the nations and push the direction of history! Yang Xingchen said.

"Yes! He got his name from the hidden ghost valley. He once taught the four disciples of Su, Zhang, Sun, and Pang, all of whom were influential figures in the Warring States Period. These disciples were all nobodies before entering the mountain, and after they came out of the mountain, they all shined, and they were famous through the ages!" Wu Yaoxia said slowly: "According to records, there is a valley near Yang City in the Eastern Zhou Dynasty, with high hills and deep ravines, lush forests, flashing ghost fires, unfathomable, not like a place where people live, so it is called 'Guigu Ridge'. ”

"In the valley lived an old man who was revered as Guiguzi, who read books, meditated, collected medicines, and cultivated on the mountains every day, and lived an isolated life without interacting with the world. ”

"He is thorough through the heavens and the earth, and his knowledge is profound and unparalleled: 'One is mathematics, the sun and the stars are like latitude, in the palm of his hand, accounting for the past and the future, and everything is verified; the second is military science, six Tao and three strategies, infinite changes, arranging formations and marching, ghosts and gods are unpredictable; third, he is traveling to study, he has a wide memory, he is wise and reasonable, he is reasonable, he is eloquent, he is speechless, and he is not in his mouth; fourth, he is born to learn, cultivate his true nature, and take food and guidance, but he is sick and prolongs his life, and he soars into an immortal. ’”

"You see, Guiguzi can breathe and cultivate. He also often collects medicines, and it is estimated that he can also make alchemy. And the Warring States period where he was located was after the Spring and Autumn Period of the Confucian Sage, and there was not much aura in the outside world, which was not enough to cultivate with the breathing method. But Guiguzi can still prolong his illness and become an immortal, which shows that he is still successful in cultivation. He may have found the secret realm, and he also figured out that he could freely enter and exit the secret realm by putting on and taking off the hidden spirit suit, so he has been living in seclusion in the ghost valley. I think the possibility of a secret realm in the Ghost Valley is very high!"

"Well, there's a good chance that there's a secret realm. Yang Xingchen asked, "Then where is this ghost valley?"

"It is about 800 kilometers away from Shanghu City in Yunmeng Mountain, Henan Province. You can take a plane to Zhengzhou City, and then go to Yunmeng Mountain, there are probably more than 100 kilometers of road. ”

"Well, it's very clear. It's well worth exploring. You just said that you found some, so is there anything else?" asked Zhu Yan.

"Yes, in the era of King Weilie of Zhou, that is, at the end of the Spring and Autumn Period, there was a person named Kuang Customs, and he had a total of seven brothers, all of whom had Taoist skills, and they lived together in the mountains. Their deeds of seeking immortals were known to the imperial court. So, Zhou Tianzi repeatedly asked him to go out of the mountains to help, and Kuang Shu also avoided it many times and dived into the mountains. Later, the Kuang Vulgar Seven disappeared without a trace. The mountain was later renamed Lushan. Wu Yaoxia continued.

"It should be that in order to avoid trouble, the seven Kuang Vulgar brothers devoted themselves to cultivation, and hid in the secret realm and did not come out, of course they couldn't find them. ”

"Is it the Lushan with a big waterfall?" asked Ding Lingling.

"Yes, it's that Lushan. There is also a poem written about Lu Shan: I don't know the true face of Lu Shan, only because I am in this mountain. Wu Yaoxia said.

"Lu Mountain's ascending dragon tyrant, the trick that can make the waterfall flow backwards is also practiced in that Lu Mountain, right?" Wu Yaohua said excitedly.

"Yes, so you've seen that anime, brother. Wu Yaoxia said with a smile.

"The scenery of Lushan is very good! Even if you can't find the secret realm, it's good to have fun~" Ding Lingling said with a smile.

"Well, you checked these two places well, are there any other places that are suspected of having secret realms?" Yang Xingchen looked at Wu Yaoxia and said with a smile.

"Uh...... No, I checked it for a while last night, and I didn't find much useful information. Wu Yaoxia said a little weakly.
