While Zhang Xuan was talking to the evil god, he had already walked to the green mountains and clear waters covered by a whole fog. A large area of ​​thick fog enveloped this mountain oasis that appeared in the desert.

Zhang Xuan was always thinking about what the evil god had just said. In ancient times, the body trainers could use the power of their bodies to hurt the spirit body, but now Zhang Xuan doesn’t even know what the spirit body is, so how can he use the body to hurt the spirit body?

Zhang Xuan looked at the place covered by thick fog in front of him, and could only sigh in his heart that he was weak and had too many magical things that he could not understand.

In front of this oasis, the evil gods were quite interested in discussing it.

"There is still a very complete magic array in this Loulan ancestral land, which is quite rare. There are very few magic arrays now. It takes a lot of effort to crack them."

Zhang Xuan walked into the thick fog. With the existence of an evil god, Zhang Xuan would naturally not be stingy with his own questions. He would ask any questions that he didn't understand.

"What is the principle of the formation?"

Zhang Xuan walked in the thick fog. The thick fog spread out makes people lose their vision three meters away. Zhang Xuan seemed very curious about all this. Overall, the formation that Zhang Xuan had seen the most were the spirit gathering array and the spirit dispersing array. The first contact with the formation was from the elder Tang, but the elder Tang could not explain clearly what the formation was.

But Zhang Xuan knew that existences like the evil god would definitely be clear.

As expected, after Zhang Xuan asked the question, the evil god gave the answer.

"In fact, everything that can be displayed in this world is a kind of energy transformation. For example, tall buildings are nothing more than mixing steel and concrete together. Steel and concrete are a manifestation of energy. Besides, the appearance of fog is nothing more than when cold air flows through the warmer water surface. Water vapor will quickly enter the atmosphere through evaporation and gradually drop below the dew point to condense, and finally form fog. The fog is composed of tiny water droplets that are evaporated from the surface of the earth and are formed by the influence of cold air and are suspended in the air. Fog itself is a thing that exists in this world. You only need to use a special method to block this energy in one place. The equivalent change causes qualitative change, which can form the scene you are seeing now."

Zhang Xuan was quite suspicious, "Can you still learn this knowledge when your spirit body is broken?"

"Of course not."

The evil god replied, "I want to tell you that someone proposed this theory tens of thousands of years ago in the central civilization of the earth. Do you believe it?

In fact, a long time ago, the civilized civilization in the center of the earth also lived on the surface.”

Zhang Xuan opened his mouth and did not answer.

"There is nothing to be understood."

The evil god said again, "Let's not talk about the different existences of the two civilizations. Take the present for example. In Yanxia, ​​online mobile payment methods have been popularized to the whole people. But if you go to a country in the western continent where everyone has to work hard to dress and eat, you say mobile payment, they may think you are a fool. However, after decades, that country develops into Yanxia now. Their latest research level may be something you often use now. The gap between the existence of surface civilization and the earth's center civilization is here. The formation of the formation is to use some special means to block the energy, just like a mechanism, and it will be activated when used. Of course, with the current technological means of surface civilization, it cannot block energy, so I said that this kind of complete formation is rare."

"oh?"

Zhang Xuan was slightly curious, "What do you mean is that these formations are probably left by people from the earth-center civilization?"

"Of course."

The evil god spoke with certainty, "If it weren't for the earth's center civilization, how could he have a formation with the technological means on the surface?

This is simply an issue that is not worth thinking about. Earth-center civilization has appeared, but it may be just one or two people who lost their way and appeared on the surface. They could not find their way back. So they started a sect and passed down the tradition. Local people have powerful technological means. When they came to the surface hundreds or thousands of years ago, they were easily regarded as immortals and gods by people at that time. After all, Earth-center civilization and surface civilization can be figured out, but the road was blocked. Of course, as far as I know now, there have been two channels to the earth-centered earth-centered earth-centered earth-centered earth-centered earth-centered earth-centered earth-centered earth-centered earth-centered earth-centered earth-centered earth-centered earth-centered earth-centered earth-centered earth-centered earth-centered earth-centered earth-centered earth-centered earth-centered earth-centered earth-centered earth-centered earth-centered earth-centered earth-centered earth-centered earth-centered earth-centered earth-centered earth-centered earth-centered earth-centered earth-centered earth-centered earth-centered earth-centered earth-centered earth-centered earth-centered earth-centered earth-centered earth-centered earth-centered earth-centered earth-centered earth-centered earth-centered earth-centered earth-centered earth-centered earth-centered earth-centered earth-centered earth-centered earth-centered earth-centered earth-centered earth-centered earth-centered earth-centered earth-centered earth-centered earth-centered earth-centered earth-centered earth-centered earth-centered earth-centered earth-centered earth-centered earth-centered earth-center

"Two?"

Zhang Xuan suddenly stopped and frowned, "You're sure."

"Of course, if you can't even find such a thing, why should I go back to the center of the earth?"

The evil god spoke, "A passage appeared a few days ago, just in Kunlun Mountain. I remember suppressing a heroic spirit there. The opening of this passage should have something to do with that heroic spirit. But for some reason, the passage suddenly disappeared halfway after it was opened, which was particularly strange."

"Kunlun Mountain!"

Zhang Xuan's eyes were full of solemnity. Wasn't that the place where Li Yongcai made an appointment with Xuantian and others to kill evil spirits? Could it be that the opening of the passage has something to do with Senior Xuantian and others?

If this is the case, if Senior Xuantian and others mistakenly enter the Earth-center civilization, and with the gap between the Earth-center civilization and here, Xuantian and others will definitely suffer a great loss! “You don’t have to worry.”

Although the evil god was in the jade pendant, he could still see Zhang Xuan’s current expression. "I can feel the energy that broke out in Kunlun Mountain that day. The three energy that appeared in Kunlun Mountain can be called the top combat power of the current surface civilization. You must be clear that although there is a big gap between the two major civilizations, the group of people standing at the top actually has not much difference. It is still the metaphor just now. Even the backward Western continents also have top rich people, with a net worth of 100 billion, which is the same as the top rich people in Yanxia. However, there may be more than a dozen such rich people in Yanxia, ​​and there are only a few in the entire Western continent. Do you understand?"

When Zhang Xuan heard the evil god say this, he breathed a sigh of relief. Not only did his concerns about Xuantian and others have decreased, but his concerns about the entire surface civilization have also decreased.

After all, judging from the information I received before, the earth-center civilization can completely crush the entire surface civilization, but if the top combat power is not much different, the earth-center civilization may not be completely crushed.

Zhang Xuan can be said to have fought since childhood. He knew very well that with the same top combat power and being crushed with the top combat power, what is the difference? Even if only one person can compete with the other party, it will make the other party a little more afraid.

"What about another passage?"

Zhang Xuan asked again.

"Other one, haha."

The evil god chuckled, "Isn't it in your hands."
Chapter completed!
