All things in the world have spiritual roots. The so-called spiritual roots are self-consciousness, just like the human soul. If there is no spiritual root, it will be just a pure energy group and completely annihilated.


    Long Bufan knew that the wind spirit understood what he was talking about, so he threatened the spirit root and subdued the wind spirit with spirit root, which was much more powerful than the wind spirit without spirit.


    For example, two swords are made of the same precious mineral iron. They are equally sharp and cut iron like mud. However, one of them breeds spirituality. For martial artists, which sword is more suitable?


    Of course, when there is a choice, the warrior must choose the spiritual sword. In combat, the combination of man and sword produces extraordinary combat effectiveness.


    This is why long Bufan plans to keep the spirit root of the wind spirit. As for the forced absorption of refined blood and evil thunder, the situation is relatively dangerous.


    First, the blood drinking evil thunder contains a trace of the ghost will of different demons, which must be forcibly erased. If you are careless, you will die.


    Second, the purple lightning needle in his body already has its own spirituality. There is no need for the thunder spirit with spiritual roots, as long as it absorbs refining and enhances energy.


    "Whoosh!!!"


    Under the dual stimulation of despair and fear, Fengling became restless and struggled wildly to resist. However, when he heard the cold drink of long Bufan, the rotating wind speed obviously slowed down a little, as if he was hesitating.


    However, this hesitation lasted only less than two breaths, and then struggled and resisted again. Like this spirit of heaven and earth, it itself has a proud dignity. It is naturally difficult to make it yield to human beings.


    "Oh, stubborn." long Bufan said in surprise.


    Under the blockade of space turbulence, Feng Ling could not escape at all. Long Bufan was not in a hurry, and the spirit consciousness slowly sank into the Dantian.


    "Buzz --!"


    The right hand of long Bufan was raised, and a complex and ancient light array suddenly appeared in the palm, vaguely emitting an extremely mysterious energy breath.


    This ancient light array is the ancient yin-yang array.


    "Yin Yang array, reverse heaven and earth!"


    The Dragon Bufan whispered, and the array pattern in the palm suddenly and strangely turned slowly like a gear. Then, with the rotation of the array pattern, a stream of obscure black energy also spread out quickly, like poisonous snakes swimming around the wind spirit.


    In the face of space turbulence, Fengling may still have the idea of escaping by chance. However, surrounded by these black energies, it finally feels the terrible smell that can completely annihilate it. The whirlwind is momentarily still and no longer resist.


    The dragon''s extraordinary eyes were awe inspiring and his body moved. He directly glanced towards the wind spirit and stretched out his left hand. Seeing that the small whirlwind seemed to be summoned, he immediately flew to his palm to show his submission.


    For the sake of safety, he cut his finger and forced a drop of life essence blood. Immediately, he turned the spirit power to his finger, drew the drop of essence blood, outlined a scarlet Rune in front of him, and finally directly branded it on the wind spirit.


    This Rune condensed with spiritual power and life essence and blood is actually a soul Rune contract.


    The soul contract is divided into three types, namely master-slave contract, destiny contract and equality contract.


    Life contract: life and death together, life and death together. The contractors know each other the best. In general, a person can only have one life contract.


    Equal contract: equal dignity, and the contractors shall not hurt each other.


    Master servant contract: the contract is a master servant relationship. The master can restrict and punish the servant. The servant cannot rebel or attack the master. He will obey the Lord forever until he disappears.


    Obviously, the rune contract set by long Bufan for the wind spirit is the relationship between master and servant. This is the most secure way for this spirit thing that exists in the body.
