The cold air in the depths of the ice castle is pressing, and it is a good place for Xiao Nan to refine his body, and he now has a lot of immortal spirit veins on his body, and he has the overlord elixir, so he has to raise his cultivation to the immortal king realm in it.

As for Ling Shuiyun, she has an ice immortal root, so she doesn't need to be afraid of the cold at all, since she has come to this place, she must go in to find out.

The only thing that made Xiao Nan feel at ease was Ye Qianyan, after all, Ye Qianyan didn't need to be afraid of the cold like Ling Shuiyun, nor did he have a strong body like Xiao Nan.

If she returns to the entrance of the Ice Castle, I believe that it will not be a problem for Ye Qianyan, who has the Heavenly Witch Tyrant Technique, to protect herself, but if she continues to go deeper, not to mention the cold and cold wind that comes and goes like electricity, even the increasingly powerful cold air is enough to make her completely unbearable, and it is Xiao Nan who will let Ye Tianyan go back to the entrance of the Ice Castle.

Ye Tianyan hesitated for a long time and asked, "Can I enter your small world?" so that I won't be attacked by the cold wind, let me stay alone at the entrance, I'm a little scared." ”

Xiao Nan thought about it, but he didn't refuse, but just about to agree, he remembered what Miao Ling told him, his small world was still very imperfect. After probing in the small world with his divine sense, he knew what Miao Ling's words meant.

It turns out that at this moment, his small world is also cold, although it is not ice and snow, but the temperature is not much different from the outside world, this phenomenon is enough to show that at this moment, his small world is still not like the small world owned by the power of the heavenly realm, it can be its own world, at least it is also affected by the external environment.

Xiao Nan's divine sense came to the palace in the small world, carefully probed, and found that Xianle's body in the ice coffin was not affected in the slightest, so he was slightly relieved.

found Duoduo's location again, and saw that Duoduo's surroundings were not invaded by ice, so he couldn't help but nod secretly.

After instructing Duoduo a few words, Xiao Nan withdrew his divine sense from the small world, and said to Ye Tianyan: "Of course it's not a problem to enter the small world, but I don't know what will happen later, if you can, I advise you to stay at the entrance of the ice castle, which is relatively safer." ”

Ye Tianyan shook his head resolutely, and always insisted on entering the small world, Xiao Nan had no way to do this, so he had to let her enter the small world, stay with Duoduo, and help take care of Duoduo by the way, so as not to complain when Duoduo came out.

Ling Shuiyun and Xiao Nan were left, the two glanced at each other, smiled knowingly, and then continued to walk along the ice passage.

The further you go, the more pressing the cold air becomes, and you can meet the cold ice wind from time to time, but Xiao Nan has already taken precautions, and when the old man has a foresight, he jumps high, and almost every time he can successfully dodge it.

To Xiao Nan's surprise, those cold ice gangfeng had no effect on Ling Shuiyun at all, Xiao Nan was still startled when the cold ice gang wind hit Ling Shuiyun, but Ling Shuiyun was still alive and kicking after a long time, which is simply a strange thing.

Thinking about it, Xiao Nan could only attribute everything to the role of the ice immortal root, and it was precisely because of the particularity of the Ling Shui Yun ice immortal root that he was able to completely ignore the cold qi of the ice fortress and even the cold ice wind.

After walking for about half an hour, the ice passage still has no end, and he doesn't even know where it leads, but the cold air around him has become more terrifying, and even Xiao Nan can't help but tremble in his legs.

Despite this, Xiao Nan's physical strength is also increasing little by little, so it is not a bad thing for him, but it is still a good thing, and I think that as long as it is cold to a certain extent, his physical strength will be further improved.

Another half an hour passed, and the ice passage suddenly split into two, one up and one down, and the upper and lower passages were endless.

Ling Shuiyun closed his eyes, pondered for a moment, and said, "There seems to be a voice in my heart that has been calling me, it tells me to go down, I think there must be something good down there." ”

Xiao Nan's face was solemn, and he looked down, although he didn't know what voice appeared in Ling Shuiyun's heart, he finally nodded.

The two of them walked down, descending thousands of ice steps in a row, and the cold air at the bottom was even more terrifying, even if Xiao Nan had already run the refining body ** to the extreme, he was still a little unbearable, his legs were trembling, and the whole person was stiff to the extreme from top to bottom.

Ling Shuiyun couldn't help but be a little worried about Xiao Nan's situation, but the further down she went, the stronger the call from the bottom of her heart became, she knew that her feelings would not be wrong, and there were definitely good things below.

"Why don't you stay in this place first, and I'll go down and have a look, and I'll come up right away." Ling Shuiyun grabbed Xiao Nan's arm and whispered in Xiao Nan's ear.

"I can hold it now, and if I can't hold it anymore, I'll just wait where I am, although rest assured, I won't joke with my life. Xiao Nan waved his hand a little stiffly, revealing a smile that was not very good-looking.

The two continued to descend hundreds of ice steps, and suddenly came to a hall, the four walls were empty, but densely packed with forks, and after a cursory glance, there were hundreds of forks.

"Do you want to go again?" Xiao Nan looked at Ling Shuiyun, his lips were a little pale at this time.

"There's still a long way to go. Ling Shuiyun nodded.

"The cold here is already very scary, if you go again, I'm afraid that even if my refining body ** is extraordinary, I still can't bear it, I'm still waiting for you in this place, you found what you want, first send a message to me with a communication bead, so as not to worry me." Xiao Nan said softly.

Ling Shuiyun already had this meaning, but now that he heard Xiao Nan talk about it, he agreed without thinking about it, and looked at it uneasily, seeing that Xiao Nan was a little colder, but there was no danger, so he put his mind at ease, chose one of the many forks, and disappeared from Xiao Nan's sight.

Seeing Ling Shuiyun leaving, Xiao Nan sat on the ground, closed his eyes, and a trace of pain appeared on his face. In the blink of an eye, a thin layer of ice rose from the surface of his body, getting thicker and thicker, and it didn't take long for the effort to become as thick as a brick, and in the blink of an eye, it had become an ice sculpture.

Before the ice sculpture turned into an ice ball, a force erupted from the ice sculpture, Xiao Nan successfully broke the ice, although his body was blue and purple, and it was very scary to be frozen, but only he knew that his physical strength was increasing geometrically.

After repeating this cycle several times, Xiao Nan's physical strength was directly increased from a fifth-level immortal body to a sixth-level immortal body, and the speed of improvement was unimaginable, and it was precisely because of the increase in physical strength that his ability to resist cold suddenly increased a lot.
