Chapter 308: A City Without Night

"Everyone, stop."

Just after everyone was hurrying towards the huge city beyond the mountains for nearly two hours, Qiu Mu, who was more than 20 meters behind Xingying, suddenly shouted: "Brother Ying, look. ”

"What's the situation?"

Xingying stopped his steps and turned back to ask.

"Qiu Mu, what did you find?" Everyone also quickly approached and looked at Qiu Mu suspiciously.

"You see, the entrance to the cave we just came in is gone." Qiu Mu stretched out his hand and pointed to the entrance of the cave where the group had just come, and said worriedly.

Only then did everyone look in the direction pointed by Qiu Mu's finger, only to see that the entrance to the cave when they came just now on the opposite side had disappeared strangely. It was as if the entrance to the cave didn't exist at all, and in just half an hour, it completely disappeared from the cliff.

"Hiss" Zewen gasped: "This is impossible? Could it be that the cave we just entered just disappeared out of thin air? ”

"It's weird!"

"Is it not where we just came in?"

"Yes, Qiu Mu, are you mistaken?"

"That's it. You can't go wrong. ”

Zhen Yu, Diao Mingling, Blue Wolf and Qiu Mu thought for a while.

"Don't use common sense on the ground to understand everything here, as I told you before, everything here cannot be understood with common sense." At this time, Han Youyun said in a solemn tone: "If it's gone, it's gone, and after we enter Xianbei City and reveal the secrets of the Xianbei clan, it's not too late to come back and find an exit." Here, there should be absolutely more than one exit. ”

Han Youyun said and looked at the Torture Eagle, nodded to the Torture Eagle, and then rushed forward.

"Brother Ying, this is too weird, if it is according to what Senior Han said, then we have now entered the maze laid by the Xianbei clan in advance?"

"Yes, Brother Eagle, I feel that way too. Ever since we entered the cave entrance, there has been a pair of invisible eyes that have been secretly watching us. No matter where we go, we can't escape the surveillance of those eyes hidden in the dark. This feeling is so strange! ”

Tianwu and Sun Dongxu said to Xingying in a solemn tone.

"I feel this doubt of yours, too, but that's why we have to keep exploring. Only when we get to that city and find the Xianbei people can we uncover all these strange events. Go, hurry to the city. ”

The Torture Eagle froze out of the corner of his eyes as he spoke, and after carefully inspecting the original cave exit, he turned and hurried towards the huge city beyond the mountains in the distance.

"Brothers, there are more and more doubts, the time has come to test us, we must be careful to deal with it." Sky Dance also nodded heavily, and rushed over after the Torture Eagle.

Then, Zheng Wei, Yun Xin, Sun Dongxu, Qiu Mu and others hurried towards the mountains.

After about six hours, Xingying and the others followed the ancient road in the mountains all the way to the west, and finally came to the bottom of a strange and steep peak, and the huge city beyond the mountains also clearly appeared in front of everyone's eyes.

"Brother Ying, the huge city in front of us is only about fifteen kilometers away from us now, you see, judging from the construction of the city's city walls, the scale of that city is not smaller than the old Beijing city!" After everyone came to the bottom of the mountain, Tianwu looked at the huge city on the other side of the mountain peak and said in surprise.

"Yes. The scale of this city is so huge that if it were on the ground, it must have been able to accommodate two or three million people. But this is underground, and it's still unknown how many people there are in the city!? The Torture Eagle nodded, thinking for a while.

Sun Dongxu also nodded heavily, and said resolutely: "I think although this city is huge, there shouldn't be many people in the city." Think about it, if there were two or three million people living in this huge city, how much would they need for daily necessities? Where do these daily necessities come from? As we all know, this underground space is completely isolated from the ground, and the materials in this underground space alone are not enough to support the survival of so many people. So I concluded that there should be no more than 100,000 people living in this huge city. Moreover, there should be other places in this underground space that we do not know in addition to the huge city we see in front of us, otherwise, it would not be possible to explain where the materials they need to live come from. ”

"Dong Xu's analysis makes sense, and I agree with Dong Xu's analysis." Zhang Jiajun looked at Sun Dongxu, and then said: "Brother Ying, do we enter the city immediately, or do we enter the city after carefully understanding the deployment of all parties in the city?" ”

"There's no hurry." Xingying stared at the huge city in front of him with deep eyes, and said solemnly: "At the moment, we don't know anything about this huge city, what kind of city is it?" What kind of people live in the city? How did they survive? We don't know. Blindly entering the city will only reveal our whereabouts in advance. So I mean, everybody fix it here first, and when it gets dark."

Speaking of this, Xingying suddenly stopped, as if he realized that something was wrong, his face became gloomy, he turned his head to look at everyone, and said in surprise: "Did you find it, we have entered this space for nearly eight hours, according to the time on the ground, it is already eight o'clock in the night, but why is it still like daytime here, there is no night scene at all!" ”

"Hiss"

After listening to Xingying's words, everyone gasped, and realized that the scene of this underground space was indeed in stark contrast to the ground. In other words, there is no distinction between day and night at all, if you divide it according to the time of day 24 hours on the ground, there is no distinction between day and night here, and the 24 hours of the day are in the middle of the day!

"No, look."

Just when everyone was surprised by the words of the torture eagle, Zewen on the side suddenly pointed to the sky in front of him and said loudly: "Look at the sky of the huge city in front of you, it is dark, it is dark."

When everyone heard the sound, they saw that the sky of the huge city in front of them was gradually dimming in a form visible to the naked eye, and gradually turned into a red glow from the previous white expanse, reflecting the huge city in front of them in a red glow.

"What the hell is going on? Why did such a strange thing happen just now!? ”

"What does this strange celestial phenomenon portend?"

"Brothers, be careful, I always feel that this place is getting weirder and weirder, I'm afraid something terrible is about to happen!"

When everyone saw the strange scene that suddenly appeared in the sky of the huge city in front of them, they all became vigilant with fear.

"I see, I know." At this moment, Zhang Jian on the left said excitedly: "That's it, only then can we explain the strange scene that just appeared." ”

"What do you know?"

"Yes, Zhang Jian, what do you know? Tell us what's going on. ”

After Diao Mingling and Zhen Yu heard Zhang Jian's words, they immediately couldn't wait to ask.

Xing Ying and the others also turned their heads to look at Zhang Jian with an eager expression, wanting to reveal the secret hidden in the strange scene that happened just now from Zhang Jian's next words.

"Say it, Zhang Jian, see if it's the same as I think." Han Youyun turned his head to look at Zhang Jian appreciatively, and said meaningfully.

"Hey, Elder Han, you know too?" Tong Yan raised his eyebrows, and glanced at Shen Jun on the side with deep meaning.

Shen Jun also looked at Tong Yan, and then made a silent gesture to signal Tong Yan not to speak, and looked at Zhang Jian and the two of them with deep eyes. Obviously, Tong Yan and Shen Jun were surprised by the conversation between Han Youyun and Zhang Jian in their hearts! Because the two of them from the Heavenly Fox Valley, one of the three major tantric sects, knew best in their hearts that the strange scene that happened just now was the legendary Crypt Celestial Phenomenon. In other words, the strange scene that happened in the sky above the huge city just now was not actually a mysterious phenomenon, but in the underground space, although there was no sun to provide a light source, there was an energy that could support the light of the underground space. This energy is scientifically called geothermal optical energy, which is a phenomenon that can emit light under the activity of volcanoes in the earth's interior.

When the volcanic lava from the interior of the earth gathers together, and after years of precipitation, the volcanic lava will gradually cool down, but there is still molten flow around the cooled lava, and in the space formed by the cooling of the lava, you will see the molten flow phenomenon on the periphery of the lava.

"Yes, I know a little bit about the geological formations inside." Han Youyun said lightly: "Zhang Jian, you can say it, see if what you think is the same as what I think." ”

"Yes." Zhang Jian nodded, and then said everything he imagined

When Zhang Jian finished speaking, everyone suddenly woke up and said: "I see, I see." ”

And Tong Yan and Shen Jun both nodded heavily after listening to Zhang Jian's words. Obviously, what Zhang Jian said was not inconsistent with what they had learned in Heavenly Fox Valley.

And Han Youyun nodded heavily and said, "Yes, what Zhang Jian said is good." What happened just now is not a mystery. It's just that most of you don't know the geological structure of the Earth's interior, which is why you have such a surprising reaction. But "

Speaking of which, Han Youyun suddenly realized something? He stopped abruptly and didn't continue.

"But what? Han seniors! ”

Xingying turned his head to look at Han Youyun and asked suspiciously.

After hearing Han Youyun's sigh, the people who were already relieved suddenly lifted their hearts again, and looked at Han Youyun suspiciously
