The degree of cooperation in signing the blood contract is divided into seven types: red, orange, yellow, green, blue, indigo and purple from low to high.

In general, the rules of the world of Warcraft are very simple: the strong are respected, the weak eat the strong, and the fittest survive. There are no such deceitful and complicated rules in the human world.

Quite simply, if Warcraft thinks you are stronger than it, then it will obey you, listen to you, and have no other ideas. Therefore, when a cultivator signs a blood contract with a Warcraft, he first convinces this Warcraft and is unable to move, so that it thinks from the bottom of his heart that you are stronger than it, and it is willing to cooperate in signing a blood contract with you. This kind of blood contract has a relatively high degree of cooperation, and it is generally either indigo-level or blue-level. Unless the strength of the cultivator is far superior to that of this demonic beast, or the physique and surname of the cultivator are very consistent with this type of demonic beast, it will be very rare to be lucky enough to have a purple-level cooperation.

However, high-level demonic beasts are often stronger than humans of the same level, and the more high-level demonic beasts are, the more so, a demonic beast that has cultivated to the peak of the seventh order and is about to usher in the heavenly tribulation is more than one or twice as powerful as an ordinary purple-level primordial god. Therefore, those sixth- and seventh-order demonic beast cultivators were often difficult to defeat alone, and they usually hunted in groups. In this case, after being defeated, a high-level demonic beast forcibly signs a blood contract with a cultivator, and the degree of cooperation is often not very high, usually a yellow or green level of cooperation.

As for the coordination between the red and orange levels, this is generally the case in large giant families or royal families. The ancestor of the family or the palace defeated the high-level Warcraft, and handed it over to those who were still at the level of the Yuanshi Yuan or even the Yuan Disciple level to sign the blood contract, so the purpose of signing the blood contract was either to find a Warcraft that had the ability to protect the master, or to form a Warcraft legion, and the cooperation between the red and orange levels basically ruined the hope of this Warcraft advancement.

Warcraft has self-esteem, you are stronger than it, it is willing to sign a blood contract with you, if you are far weaker than it, how can it cooperate to sign a blood contract with you? If it is not for the effect of the blood contract, it is possible for it to kill you, because most Warcraft are murderous and murderous, which is closely related to their living environment.

Generally speaking, the more the difference between the cultivator and the Warcraft who signed the blood contract, the lower the degree of cooperation. But there are exceptions, and that is the Warcraft egg. High-level Warcraft eggs are often very rare, firstly, not all Warcraft lay eggs, and secondly, Warcraft will value their eggs more than their own lives, and want to snatch their eggs unless they kill it.

If you sign a blood pact with a Warcraft egg before it hatches, then congratulations, you've earned it. The degree of cooperation is at least the indigo level, and often if the cultivator and the surname of the monster are similarly matched, a small part will reach the purple level of cooperation. The only flaw is that the juvenile period of high-level Warcraft is often relatively long, maybe when it grows to maturity, you may have returned to the West, but those giant families don't care, they have a way to accelerate the rapid growth of Warcraft. And the juvenile period of low-level demonic beasts like the Wind Fox is much shorter, and it grows to maturity in a few months, but as a price, the lifespan is shorter than that of ordinary demonic beasts.

Therefore, there are pros and cons to various methods of signing blood deeds, and it is not possible to say with certainty which one is better, and you can only choose the most suitable method for yourself according to your personal situation. It is worth mentioning that in the previous life, when Lin Nantian recovered the Wind Fox and signed the blood contract, the degree of cooperation was indigo-level, and Lin Nantian had been wondering if it was because the degree of cooperation was not purple-level, so the Wind Fox had been trapped in the sixth order and could not be promoted to the seventh order.

"Degree of cooperation blue level?" Lin Nantian's brows furrowed, it was worse than the indigo level in the previous life, what was wrong?

In fact, Lin Nantian didn't know that in the previous life, when he subdued the Wind Fox, the Wind Fox was already in the mature stage, and the Wind Fox in the mature stage and the Wind Fox in the juvenile stage were completely two different individuals. The mature Wind Fox is more mean, cunning, and understands people's hearts, and does not need to be taught by others at all, as if it is an innate talent. It knows who is strong and who is weak, and it knows how to cling to the strong, which is the way of survival of low-level demonic beasts. And the juvenile wind fox is like a child, whoever is good to it likes whom, and the definition of who is strong and who is weak is not very clear, simply put, it is not yet enlightened.

"Hmm...... I kind of get it. The clever Lin Nantian quickly thought of the crux of the problem, "No wonder I just helped it loosen the vine a little, and its hostility towards me was reduced a little, so that's the case!"

"But what am I going to do good to it? It's a dangerous terrorist now, and if you let it go, she'll run away, and I'm afraid I won't be able to catch up with it at my current speed." Lin Nantian pondered and meditated, but couldn't come up with any good ideas.

Lin Nantian aimed his gaze at the little fox who was still observing the changes in his body, looking at its curious appearance, it was really a child! Suddenly, under the light of his eyes, Lin Nantian saw the dried blood dripping on the ground, as if he thought of something.

"Yes, this may be able to increase its favorability!" Lin Nantian was overjoyed.

As soon as he said and did it, Lin Nantian quickly activated the Wood Yuan Force Mental Method "Ten Thousand Wood Dry", mobilizing the remaining Wood Yuan Force in his body.

"I don't know if Mu Yuan's power is enough, the red-level Yuantu's Yuan Power is really small, and the Wood Thorn that left the force in the blow just now actually used up nearly half of my Mu Yuanli. ”

I saw Lin Nantian's hands in a peculiar cross shape, and his hands kept spinning. With the constant change of his hands, Lin Nantian's mouth spat out inexplicable syllables, and when he listened carefully, he also had his own unique rhythm and rhyme.

"Wood Yuan Magic Technique - Regeneration!"

A small ball slowly formed in Lin Nantian's hands, different from Aoki Lei's destructive energy, this green energy ball contained extremely life-like energy. As a pure wood demonic beast, the little fox's sensitivity to Mu Yuanli was very sensitive, and it seemed to feel the strangeness of this green energy ball, its face was full of joy, and it wagged its tail and barked at Lin Nantian.

Lin Nantian looked at the little fox's anxious and happy appearance, and couldn't help laughing, "Little guy, don't worry, come, I'll heal you." ”

Lin Nantian controlled the green ball to slowly move in from the outside of the tree vine cage, and it was about to hit the tree vine cage, which frightened the little fox into a ball and didn't dare to move. But what was stunned was that the vines seemed to be non-existent, allowing the green energy balls to pass through slowly and go straight to the little fox.
