Until now, Nankendo has not planned to really start with Goudan, and there is no such need now, especially, after seeing Goudan's self-healing ability, Nankendo himself already knows, and the other party can be very restrained by his own means here, so that he should not be underestimated, and the other party's physical strength and spiritual power are probably also very good, not necessarily much lower than himself, or more powerful than himself.

And now, right now, Goudan is also planning to come up with some real skills, he doesn't know what Nankendo's true intentions are, and he doesn't know if the other party will use a more powerful offensive next, at this moment, his left hand exudes a cold air, and the entire left fist is covered by a thin layer of frost, and his right fist exudes a hot aura, and on the entire right fist, a trace of fire actually ignited, and he felt a certain heat.

Nowadays, the left half of the dog's body is already below zero, and the right half of his body is more than 100 degrees, which is a real state of ice and fire.

But in fact, the dog didn't feel any discomfort here, and even, he dared to receive a majestic sense of power, pouring into his body, making his state better than before, which came from the kind of self-healing ability in his body, so that his body was hurt by the ice and fire in the spiritual veins At the same time, almost at that moment, he restored his body and resisted the erosion of ice and fire, so he didn't have any adverse reactions now, and he was able to perform such an exercise.

The changes in the body surface of the dog egg now are precisely because he himself has performed the Ice and Fire Impermanence Method, which was changed by Nian Lao for himself, and it is a simplified version of the Yin and Yang Impermanence Law, because with the current dog egg, he cannot come into contact with the laws of the world, and for the Yin and Yang Impermanence Method, which is a practice that is very recognized by Nian Lao, if he does not come into contact with the laws of the world, he cannot learn to use and understand the two qi of Yin and Yang, and it is completely impossible to practice.

And now Goudan, naturally there is no way, to be able to contact the two phases of Yin and Yang, his current strength cultivation is still not enough, I am afraid that it will be at least a few years later, after Goudan can have the strength to reach the top of this world, at that time, or with the help of Nian Lao, he will be able to initially understand the laws of the world and come into contact with Yin and Yang.

However, even at that time, the dog egg could not turn the yin and yang qi into his own use, even after he reached the top of this world, he could not practice this yin and yang impermanence law, even after understanding the laws of the world, it was like this, and it was precisely because of this that it was able to see that the cultivation threshold of this yin and yang impermanence law was so high, it was today's dog egg, no matter how it was impossible to practice successfully, in the next seven peaks trial, it would not be of any use, if he forcibly cultivated, it would only make the dog egg, who was now just a cultivator in the Lingfu realm, disappear and return to the burial place again, this is obviously not the situation that Nian Lao wants to see。

Therefore, Nian Lao created a simplified version of the Yin and Yang Impermanence Law for it, not only greatly reducing the difficulty of this exercise, but also reducing its power by an unknown number of grades, the most mysterious part of the Yin and Yang Impermanence Law was also deleted by him, so that the current dog egg would not be exposed to it too early, but it was precisely because of this reason that even the dog egg in the early stage of the Lingfu Realm was able to cultivate such a simplified version of the Yin and Yang Impermanence Law, there was no problem, and there was no great difficulty.

Such a simplified version is very suitable for the current dog egg to practice, and it will not be devoured by himself, and the yin and yang qi that is required to be used in the Yin and Yang Impermanence Law has been simplified into the four hundred and six spiritual veins of the dog egg, three of which are the hot gas, and the cold qi in three of them, turning it into the Ice and Fire Impermanence Method, although this power is greatly reduced, but it is also what the current dog can practice, in this Lingfu realm, it is more than enough, enough to deal with any Lingfu realm monk.

Even the fifteen strongest people in the Spirit Mansion Realm, when they had the opportunity to face the dog who had cast the Ice and Fire Impermanence Method, they had to deal with it seriously, and if they were not careful, they would even be injured by it.

And the ice and fire in this ice and fire impermanence method are not ordinary ice and fire, they are derived from the fire and cold in the dog's body, and they are more powerful than the spiritual power in his body, because of this, this is the real ice and fire two qi, such ice and fire are not made of spiritual power, they are real ice elements and fire elements, and the more power they can exer, the more changes they have.

And the fire and cold in the dog's body are not ordinary powers, and they are not even the power of simple elements, although the dogs have lost such memories, but the power in his body is indeed genuine.

As early as when the dog egg was able to enter the copper candle space, before it broke through its own realm and entered the inscription realm, there was such an omen, when he was in the ice and snow in the jade carving, he obtained such a cold air, such a cold air is the origin power of the world in the jade carving, although it is only the origin power of the created world, but it is also part of the imitation of the world law, and it is precisely because Nian Lao saw through this that he thinks that this is the best substitute for the dog egg to practice the impermanence of yin and yang, there is no problem。

At that time, the last six spiritual veins of the dog were all filled with such cold qi, and the amount of cold qi was very huge, comparable to the capacity of the entire three hundred spiritual veins in the first four hundred veins, which should not be underestimated.

And in the case that the dog is unconscious, when he inscribes the magic pattern, the cold qi in the six spiritual veins in his body, half of which is transformed into the fire under the handwriting of Nian Lao, and the fire energy transformed by the two is not an ordinary fire element, that is the essence of Nian Lao, and there is a certain degree of connection with Shi Nian, but because it is the exercise performed by Goudan, even if it is the handwriting of Nian Lao, it will not attract those sand people when Gou Dan casts the method of ice and fire impermanence.
