And during the time when Nian Lao was asleep, he was still peeping at some of the dog's memories, but what he could see was still very limited, and he basically couldn't see the memory of the dog before he came to Zhaoyun Mountain, which had a lot to do with his strength declining a lot, and now, there were still too many things he couldn't see clearly, so he didn't plan to do it anymore, and he still couldn't see a lot as it went on.

Moreover, he also doesn't think that today's dog Dan can know the secrets of this world, what he needs to do is to explore this world with Dog Dan, in addition, he just can't be anxious, he needs Dog Dan to steadily improve his own strength, consolidate his own realm, and improve his strength too quickly, which will only make his foundation have some problems.

During the time he was asleep, he came into contact with the Yin and Yang Impermanence Method obtained by the dog, but at the same time, he felt a little confused, because that exercise, the Yin and Yang Impermanence Law, even in the eyes of Nian Lao, is also quite a good exercise, and the things involved in it can be said to be a lot, not at all like the ancestor who once climbed to the top of a small world, the ancestor of the carving knife, can create.

In his opinion, no matter how powerful the Carving Knife Ancestor is, he has only reached the top of this small world, and he has fallen halfway, and he can't be regarded as a peerless powerhouse at all, and it is precisely because of this that the level of the Carving Knife Ancestor is not able to create such a book of exercises, and his level is still not enough.

Judging from Nian Lao's vision, this book of Yin and Yang Impermanence, if he was young, he would also choose to compete for such a book of exercises, and after getting it, he would choose to cultivate, such a book of exercises, after Dacheng, he could even contact the realm of the laws of the world, which made him feel a little surprised, thinking that the ancestor of the carving knife would not be able to create such a book of exercises no matter what.

But at the same time, he watched the memory of the dog, and looked at it over and over again, in the world of the jade carving, he still couldn't see any clues, the world in the jade carving, it is indeed possible that the ancestor of the carving knife left, as a strong man who has reached the top of the world, there is a possibility of leaving such a means.

However, being able to access the exercises in the realm of the laws of the world is definitely not something that people in such a small world can create. Because, even if he reached the top of this small world, the strength of that monk could not even sense the existence of the world law, how could the exercises he created be related to the world law?

So from this point of view, this exercise, no matter how you look at it, it doesn't look like the ancestor of the carving knife can understand and create it, he wants to find the carving knife to ask clearly, this yin and yang impermanence method, and he came into contact with it back then, whether the exercises left by his ancestor are the same, but he can't do that, he has no possibility to act alone, if he goes with the dog, his lies will be ganged up.

Therefore, until now, he has no way to figure out who left this exercise, he can only be sure, it is definitely not the exercise created by the ancestor of the carving knife, but other than that, even he has no clue about the origin of this exercise.

In Nian Lao's opinion, even in the era of his existence, this exercise is not a mortal thing at that time, and it will become the existence of various sects competing for it, once this exercise can be cultivated to the fullest, the power that can be exerted is quite huge, but the difficulty of cultivation is also very high.

It is precisely because of this that Nian Lao is hesitating, whether to let Goudan practice this Yin and Yang Impermanence Method, or let him practice the exercises he passed on to Goudan, after he thought about it again, he still decided to let Goudan practice this Yin and Yang Impermanence Method, although he has not practiced this exercise, but he can still give Goudan some help.

..........................................

"Next, you should first suspend the breakthrough of your realm cultivation......... You need to flesh out your means, and in terms of exercises, you can practice the 'Yin and Yang Impermanence Method', and with your talent, plus the understanding and experience that I have left over from practicing this practice, you can quickly get started with it. Nian Lao said.

Although he has not really come into contact with the Yin and Yang Impermanence Method, he still understands how to sublimate a practice and approach it to the realm of the world's laws, and this kind of exercise is inseparable from it, with his opinion, even if he is in contact with this Yin and Yang Impermanence Law for the first time today, he can still understand it quickly, and at the same time, on the basis of the dog Dan also quickly understands this exercise, he cultivates it to the level of entry.

When the dog heard this, he also nodded, because he knew that it was an exercise created by the ancestor of the carving knife himself, and he must have a complete understanding of this exercise, and under the guidance of the other party, he would definitely be able to master it quickly, and there was no possibility of accidents.

And on the basis of the ancestor of the carving knife to help him, he has a high probability of avoiding the invasion of cold poison, and he has no worries, which is what he values the most.

However, what the dog didn't know was that this yin and yang impermanence method was not at all the ancestor of the carving knife back then, the exercises he created, and the world in the jade carving he went to was indeed created by the ancestor of the carving knife, and in that, there should have been the exercises he left behind, which was also the main purpose of the carving knife to let the dog egg enter it.

However, because after that, he never discussed this matter with the carving knife, so both of them didn't know that the Yin and Yang Impermanence method that Goudan obtained at the beginning was not known by the carving knife, and the exercises created by his own ancestor, and what Goudan obtained in the world of jade carving, were not at all the exercises created by the ancestor of the carving knife back then.

Although he didn't know this fact, and he didn't know why things had turned out like this, he could rest assured now, in the cultivation process of the Yin and Yang Impermanence Method, there was no threat of cold poison, even if there was really any cold poison, he didn't have to be afraid, with the existence of Nian Lao, he could resolve a lot of crises.

Nian Lao is the protector of the dog's path, and under certain circumstances, he will help the latter to practice, and will not let his life be in danger, so he must be protected.
