Xia Nai used all her strength, the true qi in her body was exhausted, her body was extremely weak, almost to the point of running out of oil and lamp, her face was pale, and she slowly fell from mid-air.

This trick 'absolute zero' is what she has comprehended in the year of Tiannan Island, the ability in the body is exerted to the extreme, combined with the weather, the formation of falling snow, instantly freeze everything, this trick covers a very wide range, even the ability is impossible to escape, the temperature of each snowflake is terrifyingly low, like a virus, ordinary people will be frozen immediately as soon as they are touched, and the blood and heart will also be frozen, which is enough to kill, which is why, the alien army has no survivors.

"It's over, it's all over." Xia Nai sat on the edge of the pit, leaning against a frozen ice sculpture on her back, panting softly.

She took one last look at the purple ice rose in the pit, got up slowly, and staggered into the distance.

But at this moment, in the huge pit, under the ice rose, a pair of blood-colored eyes blinked.

………………………………

The Rub al-Khali Desert is located in the southern part of the Arabian Peninsula, mostly in Saudi Arabia.

A large desert within a tectonic basin in the southern Arabian Peninsula. It covers an area of about 650,000 square kilometers. The basin is mainly in Saudi Arabia, with smaller parts in Yemen, Oman and the United Arab Emirates. It is the largest continuous desert region in the world, accounting for more than 1/4 of Saudi Arabia's territory. It includes the southern part of the Eastern Province and most of Naguia Province. The terrain is diverse. The western part is 610 meters above sea level, and the sand is fine and soft; At 183 meters above sea level, the eastern part of the world, with sand dunes, salt marshes and small sand plains, is one of the driest regions in the world, almost uninhabited and unexplored.

Ye Chen and Lexa quickly crossed the border line and continued towards the heart of the Rub Khali Desert.

In half a day, they relied only on their legs, they crossed most of Iraq, and then played the border line into the Rub al-Khali desert, of course, during which they also had rest, because their physical strength and water needed to be replenished, and even supermen could not rush uncontrollably.

When the two of them arrived in the Rub al-Khali Desert, it was already afternoon, and the temperature gradually dropped, not as high as the horror of noon, and the pace was much brisker, and the speed also increased.

Lexa stopped at this time, Ye Chen also had to stop, he glanced around, this is a downhill slope, the surrounding is still a boundless desert, uninhabited, not even a bird can be seen, let alone a person.

"Arrived?" Ye Chen asked.

Along the way, he didn't say a word, because he knew that even if he asked, the old guy wouldn't tell him, it was better to save some physical strength and hurry, but what he didn't expect was that the place where the old guy took him would be so far, he thought it wouldn't take long to arrive, until now he knew that the two of them almost crossed most of Iraq, and also crossed the border between Iraq and Arabia, fortunately he took a break on the way, otherwise he might really faint due to lack of water.

"Well, here we go." Lexa nodded, and instead of moving forward, he stood at the very top of this sandy slope.

"Here? I don't even have a bird, what are you bringing me here for? Ye Chen was suddenly full of resentment, this is the territory of al-Qaeda? Then this is too poor and sour, right, not even a house? That's not as good as other people's ISIS, at least there are a few broken houses to shade the sun.

"Who says there are no birds?" Lexa glanced at Ye Chen with displeasure on his face, this young man really didn't like what he said.

"Are you kidding me? Where do these hellish birds come from? Ye Chen was a little stunned, and then glanced around carefully, after affirming that there were indeed no birds, he said unconvinced, this kind of broken place, if there are birds that can survive, it must be a miracle.

Seeing Ye Chen say this, Lexa didn't reply, just raised his right hand to his mouth, blew it gently, and then a long whistle came out.

After a while, I saw a big bird with black feathers swooping towards them, white pointed beak, a pair of indifferent pupils, not small, two sharp claws tightly grasped Lexa's outstretched right arm, flapping its wings, and landed safely, this big bird that suddenly appeared in the desert was a vulture.

"Look, isn't this a bird?" Lexa turned back to Ye Chen and said, with a smug expression on his face.

Ye Chen was so angry that he couldn't do it, but he couldn't refute it, because there was indeed a bird in front of his eyes, he really wanted to pinch this old thing to death now, but unfortunately, he couldn't beat Lexa, so he could only clench his fists and swallow this breath, I really didn't expect that he Ye Chen would have today, he was angry with others but didn't dare to rush up and beat that person, which was not in line with Ye Chen's character at all.

In the past, it was Ye Chen who made others angry enough, when was it their turn to be angry with Ye Chen, today he met an opponent, an old rascal who was even more shameless than him.

"Haha............ Don't tease you, I didn't bring you here to see my pets. Lexa stroked the vulture's hair with her hand and said with a smile on her face.

I only heard Lexa snap his fingers, and the next scene completely stunned Ye Chen.

The huge sand field that was downhill in front of me had a boundary the size of a football field, and in an instant, it began to sink downward, and the rolling yellow sand slid downward, as if some huge monster was hiding under the ground of this desert.

Soon after, all the sand slid down, and a cross-shaped opening opened from the center, and then turned into four pieces, gradually opening in all directions, and inside the opening was a huge square iron sheet, which was like an automatic door, and also divided into four pieces, gradually opening open. The depths of the mouth are pitch black, and there is no end in sight, as if leading to hell deep underground.

"This ...... It can't be your al-Qaeda base, right? The worldview in Ye Chen's mind suddenly collapsed, such a tall base, I am afraid there are few in this world, and it is still in the middle of the desert.

Is al-Qaeda so rich? How did he not know? It is worthy of being a terrorist organization that dares to openly argue with the United States, and this financial strength alone is not comparable to that of the Taliban and ISIS.

Where the hell did these guys get all this money, oil? A secret base was built in the center of the desert, and it is no wonder that the leaders of Al Qaeda cannot be found everywhere.

"That's right, let's go inside." Lexa smiled wickedly at Ye Chen.

"Can you not go?" Ye Chen's face was a little ugly, he always felt that he would never be able to get out of the pit once he entered it, where did it lead to?

"What do you say? It's all here, do you want me to ask you down personally? Lexa still has a smile on his face, don't look at him like this, along the way, he is always vigilant, once Ye Chen has the intention of escaping, he is sure that he can catch it back, although Ye Chen's speed is fast, but compared to him, it is still a lot worse.

Ye Chen's face was full of depression, forget it, let's go in and talk about it, he doesn't believe that this old thing doesn't rest? There are many opportunities to escape, as long as this old guy is careless, he will slip away.

Ye Chen jumped and jumped directly towards the huge black bottomless pit, Lexa followed, and then the square black iron sheet began to close together, and the gate of the base was completely closed.

The two of them were falling at a high speed, about fifty meters in length, Ye Chen finally saw the ground, and then attached the true qi in his body to his legs, and with a bang, he landed smoothly, his legs stepped on another piece of iron, and Lexa also landed, but he landed very smoothly.

It is a straight tunnel, and the walls of the tunnel are all made of iron sheets, which is very solid.

"Keep up." Lexa beckoned and walked into the tunnel.

Ye Chen took one last look at the closed door, and shook his head helplessly, he regretted coming in a little, entering this ghost place, how easy it was to escape, but after thinking about it, if he resisted, I was afraid that he would be thrown in by this old guy, why tear his face with him so early? If he wants to escape, he will succeed once, otherwise he will be more vigilant, and it will not be so easy to escape again.

So now we have to wait and see what happens, and we will always find opportunities.

Ye Chen followed Lexa in, the tunnel was very long, and it was still downhill, although the slope was very small, Ye Chen could still feel it.

After about seven or eight minutes, the two finally walked to the end of the tunnel, which was a very strong tempered gate, frighteningly thick, there seemed to be a face recognition and retina recognition system on the top of the door, and there were two monitors at the door.

The huge tempered gate was slowly opened, and the scenery inside gradually came into view.

A person in a white robe and a mask, at a glance, looks like the laboratory staff in the movie, they are busy in their respective fields.

It was a large room, and in it were placed something like a water tank, and in the water tank floated a person, both male and female, all with their eyes closed, holding their legs in both hands, with a transparent tube attached to their mouths, and various instruments connected to the back of their bodies, leading to the outside.

"What is this place?" Ye Chen's voice became stern, his face turned pale, and suddenly something was in his mind, a fragment hidden in the depths of his memory was gradually being relied upon, and the scene in front of him seemed familiar.
