Tong Xin took Tang Xiaojun's hand and shuttled through the cave quickly, the speed was very fast, and this cave was not as deep as the previous cave, only a few minutes later, the two arrived at the end of the cave. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

"Strange, why isn't there here?"

To Tang Xiaojun's surprise, there was no hot or cold air gushing out of the inside of this cave, not even the entrance of the underground cave.

"It's not fun." Tong Xin pursed her mouth and said unhappily.

"Huh."

Seeing her cute appearance, Tang Xiaojun smiled, and then checked on the cave wall, but he really didn't find anything.

"Tong Xin, I want to have another baptism, why don't you take me to Tong Hefeng to see where they were baptized, okay?" Tang Xiaojun proposed.

"No, it's not fun." Tong Xin was a little unhappy.

"Ahem."

For children, Tang Xiaojun was a little powerless, and he didn't know what to say, but fortunately, Tong Xin put forward the conditions herself.

"I can take you there, but you have to carry me."

"Carrying you? All right. Tang Xiaojun didn't have to think about it, as long as he could achieve his goal, and he was just carrying a little girl, and it didn't take much effort, so he immediately nodded and agreed.

"Then come up quickly."

After speaking, Tang Xiaojun bent down, and Tong Xin jumped up without saying a word.

"Hee-hee, let's go."

-------------------------

Two hours later.

"Tong Xin, have you arrived, why is it so far?"

Although Tong Xin's weight is not large, it should be said that it is very light, but after running for two hours with such a person on his back, no matter who he is, he will feel tired, Tang Xiaojun did not expect that the place where Tong Hefeng and they were baptized would be so far away.

"Hee-hee, it's almost there, you have to come on."

Tong Xin's hand, I don't know when there was a big bouquet of wild flowers, and there was a wreath made of rattan on her head, looking comfortable.

Fortunately, Tong Xin did not lie to him, and after walking for more than ten minutes, Tang Xiaojun came to a huge hole.

The entrance to the cave was really large, much larger than the one in the cave where they lived, but it was so narrow that it seemed more appropriate to call it a crack.

"Is this it?" Tang Xiaojun asked with some suspicion.

"Well, let's get in there."

"Okay."

He believed that Tong Xin would not lie, so he didn't think about it anymore, and walked inside with his legs raised.

Within a few minutes of entering the cave, Tang Xiaojun felt a cold air current, which may be more than ten degrees below zero, of course, this was just his guess, and he didn't know exactly how many degrees below zero.

However, at such a temperature, Tang Xiaojun was still able to persevere, and it was relatively easy to insist, which could last for a long time.

Tang Xiaojun continued to walk towards the cave, but it didn't take long for him to stop again, because in front of him was the underground cave that spewed cold air.

This made Tang Xiaojun quite surprised, he didn't expect that this hole would be so close.

And this underground cave is also very large, about ten meters in diameter.

I looked under the entrance of the cave, but I could only see that it was pitch black, and I couldn't see anything clearly.

Coming back to his senses, Tang Xiaojun put down Tong Xin on his back and asked, "Tong Xin, they were all baptized here before?" ”

"Well, this is it."

Tong Xin seemed a little absent-minded, she didn't even look at him, she was just fiddling with the wildflowers in her hand, and the protective shield she released also shrouded these wildflowers.

Tang Xiaojun could feel that the entrance of this cave was continuously gushing out cold air, and the surrounding environment was also cold, but this was still within the range he could bear.

This situation made Tang Xiaojun feel a lot more relieved, but at the same time, he was also a little disappointed, if it was only to this extent, he could hold on for a long time, if there was food and water, he could even stay here for a long time.

But in such an environment, his body basically does not automatically release the air hood, and since this is the case, the idea of testing the air mask is naturally impossible to realize.

However, since he has already come, Tang Xiaojun does not plan to leave immediately, just stay here for a while to take a look, feel it, maybe there will be a discovery.

Thinking of this, Tang Xiaojun sat down on the spot, and after a few minutes, he simply took off his clothes, so that his body would get cold faster.

"Ah, shame, I'm going out to play, you can be here by yourself."

Seeing Tang Xiaojun take off his clothes, Tong Xin blushed slightly, and then ran towards the outside of the cave.

"Hey, wait."

Tang Xiaojun hurriedly wanted to call her, but she didn't care, and when she heard his shout, she ran faster, and after a few clicks, she bypassed a bend and disappeared.

In this regard, Tang Xiaojun was a little helpless, but the problem should not be big. The reason why he wanted to keep Tong Xin by his side was that he was afraid of an accident, and in case of any special circumstances, she could save himself. But looking at the current situation, it seems that she is not needed anymore.

Shaking his head, Tang Xiaojun sat down anew.

At this moment, the underground cave suddenly stopped gushing cold air, and after a few seconds, it was changed to hot air, completing a transformation.

Tang Xiaojun didn't panic, but he immediately stood up, and if the temperature was too high, he was ready to escape.

After waiting for a few minutes, Tang Xiaojun was relieved, because the temperature of the gushing heat was not too high, and it was still within his tolerance range.

However, the heat will make him much more uncomfortable than the air conditioner. In just a few minutes, his body was already covered in sweat. Tang Xiaojun thought about it, and actually began to take off his pants, which became naked, but fortunately, he was the only one here, so it didn't matter.

The underground cave entrance is very large, and the amount of hot air gushing out is also very large, which makes the temperature of the entire cave rise rapidly.

And Tang Xiaojun, who was in it, his body was also undergoing a test, although this test was not too difficult for him, but it was definitely not comfortable.

In less than twenty minutes, the entrance to the cave changed again, and hot gas gushed out.

After that, they all follow this rule, about 20 minutes or so, the cold and heat will change once.

At the beginning, Tang Xiaojun was still a little calm, but after the temperature changed twice, he suddenly felt some changes in his body.

Tang Xiaojun couldn't say what this change was, even if he felt it very carefully, he still couldn't tell what the change was, but he knew that this change was good for him.

And so it is.

After staying in the cave for nearly two hours, Tang Xiaojun had to choose to leave, because he found that he was a little dehydrated, and every time the high temperature made him sweat and lose a lot of water.

And the moment he walked out of the cave, he clearly felt that his internal qi had increased, and the number had also increased a lot.

However, what followed was a strong feeling of hunger, and the body was extremely uncomfortable, and it was unbearable, and he began to feel nauseous and retching.
