The area of the main hall of the tomb is not large, at most about 1,500 cubic meters, and the lake water poured into the stone wall uses hundreds of cubic meters every second.

From the time the stone wall cracked just now, to the time they swam out and were forced to swim back, at least ten minutes had passed, otherwise Lin Fei would not have felt suffocated.

In ten minutes, if it weren't for the encirclement of the ghost head fish, as well as the resistance of the rest of the creatures in the water, Lin Fei and Xu Ying would have swam out of the water long ago.

Ten minutes is enough to fill forty of these halls, but so far there is no sign of the water rising, which means that there is still a huge space in the tomb to contain the water of the lake, and this space is lower than the main hall.

But along the way, although the space of the tomb is large, most of the positions are higher than here, and the water flows everywhere, which is the most basic common sense of physics, so there must be a hidden space here that they don't know.

However, Lin Fei thought about it, even if there was a hidden space that they didn't know, it must be full of lake water at this time, and even if there were treasures, they wouldn't have the life to take them.

"Isn't there a place in the tomb that we haven't found, what's strange about the tomb in the tomb, if you have time to ponder this here, it's better to take advantage of the fact that the oxygen here is not exhausted, and find a way to swim to the water, I don't want to die without a whole body!"

Lin Fei, who thought about it confidently, felt that this discovery seemed to be completely meaningless, so he planned to continue diving into the water, but was caught by Xu Ying again.

"Can't you just listen to me, what if this anomaly is combined with gold-eating ants?"

At this moment, Lin Fei was even more puzzled: "What is the matter with this gold-eating ant?" ”

"It is recorded in the literature of the ancestors of the Xu family that gold-eating ants feed on gold, not from the Central Plains, from the far west, and were later used by the emperor to guard the tomb! The simple translation of this sentence is that gold-eating ants belong to foreign imports, and so are gold-eating ants here! ”

, imported from abroad, the ancients were also so trendy?

Although Lin Fei was a little surprised and couldn't help complaining, his face was still stunned, and Xu Ying had already rolled her eyes: "Do you have Alzheimer's disease, forgot, someone was killed by gold-eating ants on the first night of entering Lop Nur!" ”

"That's right, that's ...... Follow ......"

Lin Fei stammered all of a sudden, his whole breath became short, and seeing that Wang Xiuyong and the others were still killing fish in the water, he hurriedly moved his body closer to Xu Ying.

"You're saying that the gold-eating ants we met outside are likely to have migrated from the grave after Lop Nur dried up?"

"I'm afraid it's more than that, maybe the real reason for the drying up of Lop Nur also has something to do with these gold-eating ants, you think, gold-eating ants are outside the tomb, there are no natural enemies at all, they can reproduce unscrupulously, constantly devour metal mines under Lop Nur, and hollow out the entire Lop Nur underground!"

"From the tomb to the whole of Lop Nur, and even more distant places, I think you have heard the allusion of Yugong moving mountains!"

After Xu Ying's words, Lin Fei couldn't help but tremble slightly, there are hundreds of millions of gold-eating ants in the tomb alone, and these guys gnawing on metal mines will definitely make a hole appear in the ground.

a little hollow, is not able to hold a lot of water, if ...... If there is a vein, then, perhaps, it should be possible...... Get out!

"You have also seen the situation outside the tomb, it is almost impossible to swim to the surface of the water, even if we can swim to the surface of the lake, how can we get out, along the direction of the disappearance of the water, we may still have a chance of life!"

Xu Ying's words made Lin Fei both heartbroken and difficult to decide, this is a gamble, gambling with his own life.

"Hey, let's take a gamble!"

Lin Fei, who felt that there was less and less oxygen here, finally chose Xu Ying's proposal, because as Xu Ying said, even if they were lucky enough to swim to the surface, they still couldn't leave here.

At this time, there is only a little more than one day left until two days.

Call!

The two of them tried to take a deep breath to store more oxygen in their bodies, and then dived into the water, following the direction of the water that poured into the tomb lake, and decisively abandoned Wang Xiuyong and the others who were desperately killing fish.

When Wang Xiuyong and Zheng Haiyang, as well as the other four people surfaced, they were all dumbfounded.

"What about them?" Wang Xiuyong asked loudly.

In the dark, Zheng Haiyang's eyes flashed with a hint of cunning, and he said lightly: "Who knows, hurry up and get into the water, there is not much oxygen here, we can only rush out in one go, there is only one chance, we have no way out." ”

Wang Xiuyong gritted his teeth: "Follow me!" ”

Five figures rushed out of the rock wall, handing over to the crazy school of ghost head fish, but after rushing out of the stone wall, there were four figures left, but they didn't pay attention to the rush out of the water in their hearts, not to mention, there were ghost head fish around, and there were large water creatures approaching in the distance, so they were not allowed to be distracted at all.

While killing fish and going upstream, after a while, only three figures remained, and the two people who disappeared were Wang Xiuyong and Zheng Haiyang!

Zheng Haiyang knew Lin Fei's personality, and guessed in his heart that Lin Fei must have discovered something, so he shouted and rushed out, but the moment he rushed out of the stone wall, he turned back.

And Wang Xiuyong had an idea, keeping an eye on Zheng Haiyang, a scheming person, and he found out not long after Zheng Haiyang returned to the tomb, and secretly sneaked back.

As for the three of them, it is natural to keep them outside to attract fish, and not only that, but it can also reduce the few oxygen consumption in the tomb.

On the other side, Xu Ying and Lin Fei entered the nest of gold-eating ants with the current, swimming quickly in the narrow passages that extended in all directions, although they could see many drowned gold-eating ants, but the number of gold-eating ant corpses was very small.

Soon, in less than two minutes, the two of them arrived in front of a stone wall, the place where the water flow finally disappeared, this is a stone wall full of holes, but these holes, the largest is enough for Lin Fei to stretch an arm into it, and there is basically no possibility for people to go through.

Even if you can shrink your bones, it's useless!

"I'll dig!"

He used his spiritual power to convey his words to Xu Ying, and then raised the Star Mark Sword in his hand, and frantically dug the stone wall like cutting tofu, which took a full eight minutes, and then came out with a feeling of suffocation.

In the same way, he told Xu Ying with spiritual power: "I can't do it anymore, go back and take a breath of oxygen!" ”

As soon as Lin Fei's spiritual power dissipated, Xu Ying pointed to her red lips, and in Lin Fei's somewhat incredulous situation, the two of them touched each other mouth-to-mouth.

Naturally, it was impossible for the two of them to kiss in the water, but Xu Ying gave Lin Fei too much oxygen from herself, although the situation was urgent, but Xu Ying's face in the water was still red.

Lin Fei, who got oxygen from Xu Ying's mouth, continued to dig, this time, after digging for five minutes, he felt suffocated, but Lin Fei sensed through his spiritual power that the stone wall was about to pass.

Lin Fei originally planned to go back and take a breath of oxygen and continue to dig back, but Xu Ying brought her mouth up again, which made Lin Fei shocked.

Holding his breath in the water for so long, Xu Ying actually had extra oxygen for him, if Xu Ying was behind his legs, he would wonder if this Xu Ying was the legendary mermaid!

After continuing to dig wildly with the Star Scar Sword for three minutes, the stone wall was finally dug through by them, and the two of them were washed into a huge underground space by the water.

The water poured into this place turned black, and the water contained various metal mineral elements, which would cause unimaginable damage to the human body after soaking for a long time, and on the rock wall of this underground space, there were a large number of gold-eating ants climbing up!

"Hahuhu......"

The two men came out of the water, gasping for breath before jumping out of the water and landing on the uneven rock wall.

"Xu Ying, how can you hold your breath for so long?"

Lin Fei's curiosity made Xu Ying's face flush slightly again, like a freshly ripe apple, and there was an urge to go up and take a bite.

"It's turtle breathing, hurry up and climb up, stay here, I always feel restless, and the smell here is very bad, don't you think?"

Xu Ying's delicate and pointed nose moved, making her blush look a little playful and cute.

Lin Fei glanced at it, paid attention to the rising water surface below him, and said with a wry smile: "I hope God bless us to go out here, otherwise, we will escape being divided by fish, and we will be burned here in the short time." ”

The pungent smell in the air is aluminum hydride, metal calcium, etc., which should have been a metal mine here, which was eaten by gold-eating ants, but left a large number of micro-metal elements, and it will release heat and even burn when it encounters water......

Smelling the pungent smell in the air, Lin Fei really didn't know whether to rejoice for himself or feel unlucky.

However, he still said to Xu Ying: "Continue to use your turtle breath gong, although the gas here contains oxygen, it can cause permanent chemical damage if you inhale too much into the human body." ”

"Then I can't suffocate to death, can I?" Xu Ying glanced at Lin Fei.

Lin Fei pointed to his mouth generously: "I have strong physical fitness, the gas here can be ignored to my body, I need oxygen to tell me, I'll give it to you!" ”

"Bah, stinky rascal, in this case, you still want to take advantage of me, believe it or not, after I go back alive, I will tell you those people in the family, saying that you kiss me? Hum! ”

Xu Ying rolled her eyes, she didn't believe Lin Fei's nonsense at all, and quickly climbed up, but five minutes later, she felt that her body was really in a bad condition as Lin Fei said, but Lin Fei was climbing up like a vigorous tiger!

"Could it be that what this guy said is true, what kind of physical fitness does he have, so perverted?" While Xu Ying was surprised, she also thought shyly in her heart: "What should I do, I really have to take the initiative to propose it to him...... I knew that I just agreed to it, anyway, I kissed twice, and how many times it was the same? Now how do I speak? ”
