Against the backdrop of black, this white and undoubtedly beautiful body is suffocating, and every movement is showing the proud elastic cotton to the outside world.

They changed into a pair of silk and other material base pants, which were very thin, much like the autumn clothes and trousers of the north, but much thinner. Silk is soft and prevents skin friction and irritation caused by prolonged exercise.

Moreover, silk has a very sensitive temperature sensing, thermal expansion and contraction, which can be tightened when it is cold, to avoid the cold wind blowing in, trapping the heat in the body, and when it is hot, it will be opened, so that the sweat and heat on the body can volatilize to the fullest.

The air here is very cold, so after wearing these undershirts, due to the cold shrinkage, they are very close-fitting, Yun Yanuan glanced at Jenna beside her, and really felt that her current appearance was no different from naked.

The sweaty clothes room was briefly cleaned in the stream, and the two of them worked together to wring out as much water as possible in the clothes, and then hung them on the back of the backpack and slowly dried them.

The small fishnet made of lace panties once again proved its worth, and the two of them were given some protein supplements and a few sips of light salt water before they began to continue on their way.

Although the material of this undershirt is good, but in such a cool space, the warmth effect is really not as good as the jacket and trousers, the two of them are close to each other in order to keep warm, almost sticking to each other and walking forward, but still have a cold war from time to time.

According to Yun Yanuan's guess, they should have gone deep into the ground at this time, so they were so cold, they were very lucky, in the most primitive time, there were creatures living here, so there were these fish and shrimp that evolved into eyeballs, ensuring that they would not starve to death.

As the water on the side deepened, the walkable road on both sides became narrower and narrower, and finally it became a water hole completely. This proves that they have completely entered the world of underground water, Yun Yanuan remembered that there was a description on the map, out of the tunnel, you can see the wide river, then this groundwater, it is very likely that it will directly collect into the big river.

Yun Yanuan put the tent in the backpack into Jenna's backpack, tried to make her backpack empty, and then inside the backpack, she took out a slender silicone tube and blew it vigorously for a long time, and the backpack became bulging and round.

This is an inflatable layer of an outdoor backpack, which is usually used as a waterproof, but in times of crisis, when it is fully inflated, it can be used as a life jacket to float on the water.

Filled with air, buckle the trachea with a cap to prevent air leakage, and then seal the waterproof zipper on the outside of the backpack, and tell Jenna to lie on her back after entering the water and not swim with her own physical strength.

Yun Yanuan gritted his teeth and jumped into the cold underground river, the moment he entered the water, his whole body was excited, from the bottom to the top, the whole body seemed to be tightened by the tendons in the body, and his brain was hurt by the ice.

Jenna jumped over Yun Ya Nuan's back, and as soon as she entered the water, she immediately exclaimed, shivered, said that she would not stay behind, swam to the front, and got into Yun Ya Nuan's arms.

This is the best way to preserve body temperature underwater, that is, body to body, keep a certain area of non-diffusing body temperature, and warm each other.

With this inflated backpack, Yun Yanuan didn't have to take care of her, but in order to be able to pull out the knife on his back smoothly when he was in danger, he still used the back of the backpack and the belt of his trousers to buckle Jenna in front of him, so that he could free his hands.

Not to mention, this woman's back, after sticking to Yun Yanuan's chest, really felt that her body was not so cold, which had the credit of protecting each other's body temperature, and also had the effect of hormones.

Such obvious ups and downs against his body that he couldn't even think about his heart racing.

The speed of the water is getting faster and faster, and the water level is also rising, and the top of their heads is getting closer and closer to the top of the cave, at this moment, they can clearly see the convex rocks at the top, and they can't see what color is clear, like stalactites.

It was a completely natural water hole, with no traces of man-made damage, and the two of them kept an eye on the height of the rising water level, while also being careful of possible obstacles ahead.

After all, the water was so fast that if a raised rock appeared, both of them would have to be hit on their heads and bleed.

The concave rocks overhead were getting closer and closer to their heads, and by the end they had to even start dodging the obstacles, using their hands to control the speed and direction of their travel.

If this continues for a while, it is estimated that the two of them will be completely swallowed into the water, and they will really suffocate in it.

Yun Yanuan realized this, but the current was so urgent, they had no chance to swim back at all, they could only go to the dark one by one, whether they lived or died, they could only fight for luck.

In the end, the two of them could only raise their heads, keep their mouths and noses as exposed as possible, breathe in the air that was already not abundant, and occasionally hit the raised rocks above, so that they could spin in the water a few times and choke on a few mouthfuls of water.

Seeing that the water was about to fill the entire cave, Yun Ya Nuan hugged Jenna tightly, as if looking for a trace of comfort, Jenna turned her body hard, so that she was facing Yun Ya Nuan, she already knew the end, and was not ready to make any effort and resistance.

She hugged Yun Yanuan's waist tightly, and put her face on the face full of stubble, pricking her skin itchy and painful, she didn't cry, nor did she speak, all kinds of previous experiences have made her have no catharsis strength, and she has been numb to this kind of life and death.

But Yun Yanuan didn't give up, whenever he saw the slightly higher cave roof, he would grab those stones, let the heads of the two of them stick out of the water, breathe in the thin air, and comfort his cracked heart.

This kind of resistance to survival does not seem to be determined by gender, but a national identity.

The people in the land of China seem to have the spirit of struggling to the end in the face of adversity, which is not possessed by other countries and even nations.

This characteristic can be seen in the myths and legends of each nation. The sun god, in ancient times, was the most revered god, but in the land of China, there was a man named Kuafu, who was ready to catch up with the sun and take it off because he thought the sun was too hot.

There was a flood, the largest flood between heaven and earth, the Western nation relied on Noah's Ark and God's instructions, and in the land of China, it was Dayu who led the people to jointly govern the flood and defeat nature.

The mountain blocks the way out in front of my house, which in anyone's opinion, moving is the best way, but the Chinese nation comes out of a foolish man, he thinks, home is mine, you block my way out, then I will move the mountain.

The universe imprisoned me, and I used a big axe to split the world, this is Pangu. The sky leaked holes, and I used stones to fill them, this is Nuwa. Cut off my head, then I turned my chest into a face, and continued to fight with my weapon, this is the punishment of heaven. The sea drowned me, so I turned into a Jingwei bird to reclaim the sea.

In this world, there is no national myth that can be like the land of China, which is full of resistance and fights to the end against all impossibilities, this is the spirit of Shenzhou.

Therefore, before he dies, Yun Yanuan will not give up, just like on the fossil tree, he is also ready to die with a blow.

The water filled the cave and filled everything, and Yun Yanuan shone a flashlight on Jenna's face in front of her, showing an apologetic smile, he was sorry for not being able to bring her back alive......
