Mica is a rock-forming mineral that exhibits hexagonal sheet crystals. One of the main rock-forming minerals, the characteristics are insulation, high temperature resistance, but mica is very brittle, once the weight of the object, beyond its bearing capacity, it will crack like an instant!

Lin Fei never imagined that what he and the others were standing under their feet turned out to be a mica layer, and it was a cracked mica layer, and a cracked mica layer meant that the feet were hollow.

The thick mica couldn't see the situation below at all, but it made Lin Fei feel a strong uneasiness, and hurriedly shouted: "Run!" ”

Click!

At the moment when Lin Fei shouted, the mica layer under their feet instantly cracked and shattered, but Lin Fei was already on guard, with his speed and the nine changes of Lingyan, it was enough for him to escape the moment the mica layer collapsed and reach a safe passage.

However, with the rupture of the mica layer, at this moment everyone found that the pitch-black abyss under their feet was the same as the boundless passage that stretched upwards overhead, and what was even more terrifying was that at the moment when the mica layer ruptured, gravity, a strong gravity, pulled them down.

Even if the Nine Transformations of Lingyan were cast, the figure that had originally risen upwards fell sharply the moment gravity appeared.

Laugh at!

In a flash of cold light, the Star Trace Sword pierced into the rock wall like cutting tofu, Xu Ying, who had been following Lin Fei closely, decisively reached out and hugged Lin Fei's waist, and the two of them hung in the air, Wang Xiuyong and the others saw this and followed Lin Fei's example.

Bell Bell Bell ......

In the pitch-black vertical passage, the firelight burst one after another, however, all the sounds that appeared were metal collisions, which formed the rock wall of the vertical passage, which was completely stronger than all imagination, and the hardness of the rock wall was no worse than meteoric iron.

Moreover, the rock wall of the vertical passage was extremely smooth, and it was impossible to borrow force at all, including Zheng Haiyang, Wang Xiuyong and others, they all fell downward with panic and uneasiness, and completely disappeared from Lin Fei and Xu Ying's sight in the blink of an eye.

"What the hell is going on?"

Lin Fei asked loudly, the strong gravity from below made him very difficult, plus Xu Ying hugged his waist tightly, this extra person made him even more difficult, and he insisted for a while, with his physical fitness, his arm actually appeared sore, and the muscles were tired.

He has ten times the physical fitness of ordinary people, plus his strength, under normal circumstances, this kind of suspension method, even if it is a day and a night, Lin Fei will not have this kind of sour muscle exhaustion, which shows how terrifying this invisible but ubiquitous gravity is.

Under this gravity, even if he had now cultivated the Ninth Transformation Spiritual Sky of the Nine Transformations of Lingyan, Lin Fei did not have the slightest confidence to get out of the predicament in front of him.

Xu Ying also shouted in panic: "How do I know, no one has ever entered the inner tomb of the Emperor's Tomb, God knows what ghosts are here, you hurry up, I'll climb up first, and then we will step on the sword and wait for rescue!" ”

Xu Ying said as she clamped Lin Fei with her long elastic legs, and then moved her hands up a little along Lin Fei's body, which was originally an easy and simple thing, but now she is doing it, but it seems very difficult.

However, she finally climbed up the Star Scar Sword along Lin Fei's body, and then pulled Lin Fei up, at this time they were only six or seven meters away from the entrance of the passage where they came, which was nothing to them.

If it weren't for gravity, they could easily go up with a full jump, but there is no such thing in this world.

They can't be afraid of it with their bare hands, the sturdiness of the rock wall, except for the Star Mark Sword, other sharp weapons are difficult to insert and fix inside, except for waiting for rescue in place, the only thing left to pray for is that this damn gravity will disappear quickly.

However, it is more reliable to pray that gravity disappears, or wait for rescue, after all, He Chongshan and others behind them will find this place sooner or later.

"There are no outsiders now, you should tell me, where is my dad?"

Star Trace Sword, half of the sword body pierced into the rock wall, and the remaining positions were limited, so the two of them could only stand on the sword body close to the rock wall, the distance was very close, and the hot breath exhaled by Lin Fei when he spoke directly fell on Xu Ying's face.

In any case, it can't be concealed that Xu Ying is a woman and Lin Fei is a man, so face to face, body close, the oncoming heat with an honest man's breath makes Xu Ying can't help but move her eyes to the side, and I don't know if it's because she was panting and tired when she climbed just now, and a flush can be clearly seen on her cheeks.

"Before he left, he said that he would wait for us here, if he didn't see him, then he must have got what he wanted, and leave here to find your birth mother in the forbidden land!"

Xu Ying blushed, and looked a little shy when she spoke, Lin Fei was suspicious of this, although it had been determined that Zheng Haiyang and Shi Ningxiang had two hearts for him, but he also knew that the people from the Forbidden Land were not notified by Zheng Haiyang and Shi Ningxiang.

Then the only one left is Xu Ying!

For Bai Jingting, Lin Fei would not doubt it at all, after all, he still thinks that Bai Jingting is his biological father, it must be Xu Ying planning something in secret, and he even guessed whether Bai Jingting suffered Xu Ying's plot!

"Really?!"

Lin Fei replied suspiciously, at this time, suddenly, the ground shook as if there was a strong earthquake in this area, and even the extremely solid vertical passage had cracks in the huge earthquake.

The huge earthquake, coupled with the strong gravity, Xu Ying's whole person swayed from side to side, and fell off the Star Trace Sword with a stumble, and eagerly grabbed Lin Fei in a panic, and as a result, Lin Fei, who was shaking and difficult to stand firmly, also pulled down.

"Damn it!"

Lin Fei hurriedly reached out and grabbed the hilt of the Star Scar Sword, no one knew what was underneath, he didn't dare to gamble with his life, however, a crack also appeared where the Star Scar Sword was inserted, and under the weight of two people and gravity, the Star Scar Sword inserted into the rock wall broke out inch by inch.

"Oh no!"

Lin Fei shook his head, but the star trace sword that broke away did not stop as he wished, and in the end, the two people with the sword, under the pull of gravity, fell rapidly, and the further down the gravity, the stronger the gravity.

WhewW......

In his ears was the rapid fall, the powerful air current, under the gravity, Lin Fei and Xu Ying had lost control of their own whims, in the face of the power of nature, they would always be so small.

"Lin Fei, you say, will we die here?" Xu Ying panicked, this time she was really panicked, she was afraid that she would fall and break her bones, and her death would be miserable.

"Who knows!"

Lin Fei didn't know the bottom in his heart, he was also very flustered, he was afraid of everything unknown below, the temperature around him was constantly rising, but this was normal, the deeper he went underground, the higher the temperature would be, from just now to now, they had fallen at least about five hundred meters.

"Whoa, whoa!"

In the whistling airflow, there was a sudden sound like ocean waves, Lin Fei thought that his hearing was hallucinating, but he found that Xu Ying's face on the side showed the same doubts as him.

"Do you hear the waves?" Lin Fei asked loudly.

Xu Ying nodded and replied, "You heard it too?" ”

How can there be the sound of waves underground, hallucination, it must be some kind of hallucination, Lin Fei and Xu Ying both thought that they were hallucinating, but after a few seconds, the sound of the waves became clearer and clearer, and at this time, the surrounding airflow also became very humid.

"The sea, it's the sea!"

Suddenly, Xu Ying shouted, Lin Fei lowered his head, and a pair of eyes stared straight directly, full of horror and disbelief, at the end of the vertical passage three or four meters wide at most, there was actually a vast ocean, and the water waves were surging with the wind!

The light that came from nowhere made this wonderful underground world seem a little dim, and at this time, gravity also disappeared, and then, with a plop, the water surface splashed more than a meter high, and Lin Fei and Xu Ying fell into the water at the same time.

This slightly gentle water made Lin Fei and Xu Ying dare to believe that all this was not their illusion, everything here was real, this was an underground world that human beings had never explored and had not yet discovered.

In the underground world of nearly a thousand meters, there is a huge freshwater lake, a vast water surface like the sea, this discovery is enough to shock the whole world!

This is the underground world of Lop Nur, perhaps this vast sea-like freshwater lake is the Oriental Pearl that disappeared in history - the underground Lop Nur!
