"The oath of soul and blood has the highest effect. I believe you are the same." Purple tail fox after some deliberation to say such words, it said staring at Ning fan, as long as he has even a little hesitation, it will not hesitate to turn away, can no longer believe him.

But Ning fan didn't avoid his eyes and laughed frankly: "if you can increase mutual trust, why don't you do it? I believe that as long as both sides are sincere, they will be able to cooperate successfully. "

Seeing Ning fan's firm attitude, purple Tailed Fox finally moved. It knew the effect of soul blood oath. Once it made such an oath, it would be impossible to violate it. Otherwise, it would be very terrible punishment. No one could resist it, and no one would dare to violate it.

"Well, I'd like to believe you once!" Purple tail fox nodded, and then quietly wait for Ning fan to state his position.

Ning fan did not let it down, he did not hesitate to pop up a soul blood, let it float in the air. The name is not important. It doesn't matter whether the soul blood oath or the soul blood oath. The important thing is the essence. It is such an oath that is effective and can effectively restrain both parties.

Seeing that Ning fan does not hesitate to pop up a grain of soul blood, with the unique spirit talent of purple tail fox, of course, it can tell whether it is true or not, whether it is true or not, whether it is true or not, whether it is false or not, and whether it is true or not. Its expression suddenly becomes very surprised. It is really unexpected that Ning fan is not ambiguous at all.

"Yes, since you are so sincere, I won't let you down!" Purple Tailed Fox is serious and proud. Animals are proud of themselves, and once they decide something, they will not change it. In fact, animals pay more attention to keeping their promise than human beings. It said, also pop up a soul blood, fly out and ningfan fusion together.

There is no need for a specific oath. As long as two drops of soul blood merge, they can't attack each other or hurt each other. Otherwise, all the damage will be doubled on themselves, making the attacker lose more than gain. This is the most powerful effect of soul blood oath. It can be said that the consequences of violating the oath of soul and blood are very serious, which the swearing can not afford.

Ning fan did not expect, purple tail fox is so happy, it seems that his strategy played a decisive role. It's King's way to treat sincerity with sincerity and compare heart to heart.

But in the next, he found a very unexpected scene, he and purple tail fox soul blood in the process of blending, had an incredible change.

In principle, this kind of soul blood fusion is highly effective, but the process is not complicated. In general, it records the unique mark in the soul blood, and adds the force of oath into it. Once the oath is violated, it will be backfired.

However, after the fusion of the two souls and blood, they burst into brilliance, with mysterious runes looming in them. Because Ning fan has been paying close attention to it all the time, he almost opened the mind record without thinking, and completely recorded the process in the way of mind carving.

"How could that be?" Purple tail fox was also shocked. It also received the abnormal fluctuation from the fusion of soul and blood, which broke out a force and made the fusion of soul and blood very strange, which it had never heard of. But soon, he realized something, and his expression became strange.

But at this moment, Ning fan has no time to pay attention to it and focus on it. At this moment, he can't let go of any details. No matter how subtle the details are, he has to write them down completely. Especially the hidden runes are absolutely related to the talent of purple tail fox. They are extremely precious things.

Ning fan didn't know at the moment that the process of fusion of soul and blood he saw was different from that of purple tail fox. He could see the light suddenly appeared and the rune pattern loomed, but what purple tail fox saw was the light spot shining. Generally, it formed a light shaped arrow, which seemed to be branded in its soul and blood.

It's very strange, because it means that the opponent's strongest spirit attack skill will always lurk in his spirit, which is equivalent to guarding his spirit body and making him never dare to violate his spirit oath.

The reason why he is surprised is that this is an extremely rare form of oath in the soul blood way as he knows it. It is also out of the control of human beings, and it occurs spontaneously during the fusion of soul and blood.

Purple tail fox immediately thought, what it can see is this scene, so Ning fan must see is its talent spirit rune, that is its biggest secret, will he peep?

This thought made him feel uneasy, and he suddenly regretted that he should not make such an oath with him, because it might lead to the leakage of the secret of his talent.

From this point of view, it is a big loss this time, because the secret of its spirit is the most secret in the world that can not be spread to the outside world. Once it is leaked out, there will be endless trouble.

But it has come to this point, and it's already night for it to go back. Although the way of soul blood fusion is more complex and unprecedented, the fusion speed is very fast, just between a few breath, which can't tolerate the end of purple tail Fox's repentance.

Ning fan feels very sorry, because he has not yet seen clearly, just by his burning those, far from enough to let him see that mysterious powerful rune.

Can only say, through such soul blood fusion, let Ning fan confirmed purple tail fox spirit skill is talent. After the fusion of soul and blood, they separate and return to their bodies. This process is very strong. They don't need to do anything at all. They ignore their defense and will and directly force themselves to return to their bodies and integrate into the spirit. That is to say, after the fusion, they can't make the decision themselves.

"Ha ha, I didn't expect that we have come to this step." Ning fan in the end had several such experiences, and soon came out of the strong maladjustment, deliberately relaxed to smile.

But the purple tail fox has not. Its expression is constantly changing. It took a long time to realize that the human in front of it has blessed the soul blood oath. This feeling makes it feel fresh and uncomfortable. Seeing his smiling face, it is at a loss and does not know how to face him.

It can be said that the relationship between them is very special. One thing is for sure that they can no longer be hostile. Then, it is entirely possible to develop a very close relationship because they have such a foundation.

But the purple tail fox has always kept in mind her mother's instructions. The secret of her talent can't be revealed, otherwise it will be a disaster. However, when she swore to the soul, it seems that her talent secret has been revealed. What should I do? It's all about this.

"What did you see just now?" Purple tail fox is not in the mood for emotion, directly asked Ning fan.
