Xiao Ling thought of the group photo half a year ago again.

Zhou Kesheng explained at the time that the person in the photo was himself, but he had amnesia and forgot everything about the underground world and the Rob Desert half a year ago.

Is Zhou Kesheng telling the truth? Or is he deceiving and hiding something?

"All this is becoming more and more incomprehensible, is it ......" Xiao Ling looked at the last mural, looking at the black sun with claws in the blood-colored vortex, in Li Zhibao's depiction, this is a monster with some mysterious and terrible phenomenon that the ancestors of the Yu Dynasty could not understand.

"Monster ...... Could it be that all this bizarre and strange thing is related to the monsters in the depths of the earth? ”

Suspected of Zhang Shuang's sudden appearance, although it disappeared, but the worry in everyone's hearts deepened, especially Sun Tao, the look in his eyes became suspicious, although he denied that the person was Zhang Shuang, but deep down he obviously didn't quite think so, he held a searchlight, shining around, as if he wanted to find out the disappeared "Zhang Shuang".

Suddenly, he pouted softly and lost his voice: "What's going on?" Walls disappearing? ”

Everyone looked around, and suddenly found that the tall buildings around them were melting as if they were melting, especially the brightly colored murals, which were rapidly fading and dimming, and soon disappeared from the four walls of the temple.

Everything that happened around was extremely strange, and in the stunned eyes of everyone, the original magnificent and tall buildings were rapidly weathering and disappearing...... Eventually, the surrounding area turned into piles of ancient mounds, with some ruins and ruins, turning into ancient ruins that have endured thousands of years of wind and frost.

"It's ...... What's going on? Wang Lei muttered to himself, everything that had just happened was like a world away, like experiencing a fantasy dream.

Li Zhibao took a deep breath and said: "This is the immortality of the heroic spirit of the Yu Dynasty civilization, taking us to witness the former Yu Dynasty civilization and leaving the silhouette of these times, perhaps, this is to tell us some important information for these descendants." ”

Li Zhibao's words sounded mysterious and mysterious, and everyone couldn't understand it, Yu Tingting said: "This is a mirage phenomenon. ”

"From time to time, there have been reports of mirages around the world, such as people seeing ancient cities and ancient humans thousands of years ago on the clouds, a phenomenon that is rare but not non-existent. What we are seeing now is a similar phenomenon, a virtual image of a millennium ago that was preserved in the air. ”

Xiao Ling couldn't understand: "Isn't the mirage a phenomenon formed by the refraction and reflection of light?" The phantom that can appear should exist somewhere now, how can the city of a thousand years ago be revealed through time in the present? ”

Yu Tingting explained: "Ordinary mirages are as you said, but in some special places, especially in areas where the magnetic field is strong or chaotic, there will be extremely rare illusions like time has passed. In the depths of the ground in this area, there should be a large magnetic mountain, and the strong magnetic field will burn certain information and scenes under some special circumstances, like the tape of a tape recorder, which may be preserved for hundreds of years, and now because of our intrusion, the magnetic field of this area has changed, triggering these information that has been preserved for thousands of years, so that the information that has been burned in the magnetic field will reappear, so that we are fortunate to witness this precious material that has been preserved thousands of years ago. ”

Xiao Ling said: "Is there such a rare mirage phenomenon in this world? It's hard to believe. ”

I thought that the magnificent and tall buildings I had just seen, the bright and dazzling murals, I couldn't believe that in fact, everything was actually just a piece of virtual image information that had been preserved in the magnetic field for thousands of years, and the ruined walls I saw in front of me at this moment were the real appearance of this ruins.

Yu Tingting smiled: "I have followed my father and have been studying similar seemingly mysterious phenomena, this kind of mirage spanning thousands of years is not the most bizarre, and there are some bizarre phenomena that cannot be understood and explained by our current knowledge." ”

The bright and dazzling murals disappeared, and the surrounding area became a ruined wall, Li Zhibao still looked very excited, after all, these ancient city ruins in front of him represent the evidence of the existence of the Yu Dynasty civilization thousands of years ago, this discovery will shock the whole world, can advance the origin of Chinese civilization thousands of years ago, and they will also be famous in history.

A team member carrying a camping lantern is patrolling around, he is always vigilant, in this dark underground world, accidents may occur at any time, and their duty is to protect the safety of Zhou Kesheng and Li Zhibao and other scientific expedition members.

He was making his rounds when he suddenly noticed something dripping from above, and with the soft glow of the camping lanterns, it seemed that it was raining ahead.

Such an underground world, where there are rock formations above, and it will rain?

He was a little surprised, afraid that something would happen again, and he was busy reporting to Sun Tao.

Sun Tao carried a searchlight to shine through, and soon noticed that rain was dripping down from the rock layer above and falling on a rock in front of them, and the rain was pale yellow, and immediately seeped into the rock, melting a hole in the rock.

"What kind of rain is this? So corrosive? Sun Tao was startled, suddenly thought of something, and cried out in a lost voice: "Robbing water? ”

He remembered that before everyone inadvertently saw the wreckage of an airplane, which cracked the rock formation, and the robbery water that had been sealed in the rock layer flowed out, encountered air oxidation, and formed an extremely terrifying substance that can corrode everything, which is constantly melting and devouring the earth rock formation, according to Hu Shengzhe's speculation, it only takes a few days for this robbery water to completely melt the rock layer into a huge abyss, contact the magma deep underground, and then cause a magma explosion.

But how can there be a drop of robbery water from above?

Sun Tao was shocked and hurriedly shone the searchlight in his hand upwards.

The beam of the probing light is concentrated, and it can be illuminated very far, and the dark and dreary rock formation above can be faintly seen, and there is yellow water penetrating the rock formation, dripping down.

At first, it was a sporadic drop or two, and soon more and more water was dripping down, and this water fell to the ground, whether it was dirt or rock, and immediately corroded it, forming more water and swallowing it all around.

Other people also noticed this phenomenon, Hu Shengzhe gasped, instantly understood everything, and immediately shouted: "Get out of here, the water has corroded to the rock formations above, and it will soon flow down." ”
