The black dragon king's body was as indifferent as smoke, as if a gust of wind could blow it away, but in fact it was extremely tough, calcined in the incinerator furnace, and it was not damaged. At this moment, Le Kai's mind moved, appeared in the space of the bloodstain knife, looked at the black mist winding in front of him, and said suspiciously: "Black Dragon King? ”

The black smoke twisted for a moment, as if it wanted to condense into a dragon form, but it didn't succeed, it lasted less than a second, and then it dissipated, and I couldn't help but cry out with grief and indignation: "This is only one ten-thousandth of my soul, I finally woke up, and I was refined by the damn Burning Heaven Furnace to refine most of my power, so naturally it will become like this, if I am allowed to restore my true body, I can swallow this 'Burning Desert' in one bite." ”

Le Kai couldn't imagine that this terrifying black silk, its real body turned out to be a trace of the spirit of the Black Dragon King, no wonder it was so powerful, one in ten million was so fierce, if it was the heyday of strength, how terrifying it should be? At the same time, Le Kai also got a message, this place is actually called "Burning Desert", it seems that the Black Dragon King knows a lot.

Le Kai was secretly glad that thanks to the help of the incinerator he had to forcibly brand the control circle in the depths of its fright when it was unconscious, otherwise, with its arrogance and ferocity, it would be absolutely impossible to surrender to him. Unlike the incineration furnace, although it was refined into a natal magic weapon by Le Kai, there was no way to take it, because Le Kai's strength was not enough to urge it, let alone control it. It's like giving a three-year-old child the most powerful weapon in the world, but the child can't lift it at all, and if he doesn't get it, he will hurt himself.

Le Kai's consciousness spun quickly, and asked: "Black Dragon King, let's call you that! I don't care how prominent your identity was before, but now, you are my machine spirit, even if I only have my last breath left, I can control the magic circle, so that you can instantly disappear, so if there is any secret, it is better to tell it now." ”

The Black Dragon King was so angry that he trembled, once upon a time, a weak human dared to talk to himself like this? The arrogant and great Black Dragon King, crisscrossing countless time, space, stars, and universes, invincible, turning over the clouds and rain, extinguishing the dragon in one mouth, can extinguish such a small role for hundreds of millions, but now, he is still threatened by such an ant-like human, this huge contrast, really makes it collapse.

Le Kai looked at him coldly, and had already made up his mind in his heart, if this guy was really not interesting, he would destroy his spiritual intelligence with one of his own thoughts, and use his body as the power of the 'Black Dragon Battleship'. Thinking of the 'Black Dragon Battleship', Le Kai was stunned for a moment, and the Black Dragon King ...... Black Dragon Battleship, is it possible, this Black Dragon Battleship is actually made from the body of the Black Dragon King? How powerful should it be to refine such a powerful Black Dragon King into a flying magic weapon?

Le Kai shuddered, instantly realized the value of the "Black Dragon Battleship", and at the same time his mood became heavier, such a shocking value of the baby, can the black tiger give up?

After all, the Black Dragon King is an old monster who doesn't know how many years he has lived, and his wisdom is like the sea, so he quickly figured out what was going on and reluctantly accepted the facts.

No matter what happened before, the current self is just the instrument spirit of this weak human in front of him, fate is in his hands, and blindly fighting will only make his situation more difficult, if he can serve himself, collect energy to devour the restoration, and wait for himself to restore his former glory, wouldn't it be extremely easy to erase this soul mark?

"Le Kai, now you and I are one, only unity, can get through the difficulties, you have left a mark in the depths of my soul, even if I want to betray you, I can't do it, you die, I can't be spared, I naturally have to fight for our common interests. I only hope that when you become stronger, can it be up to me to help you and let me regain my freedom. The Black Dragon King said sincerely.

Le Kai was stunned for a moment, he still thought that the dragon is a noble creature, arrogant, and will never succumb to humans who are weaker than himself, and he is already planning to take out the black dragon battleship to absorb energy, but he didn't expect the black dragon king to figure it out so quickly, this has won a trace of respect from Le Kai, can bend and stretch, brave, not reflected in recklessness, see the shape clearly, do what you can, more suitable for survival.

"Okay, Black Dragon King, I promised to help you recover your strength, but it's still too early to let you go free, so let's do it, it's not difficult for me to serve you, as long as you sincerely help me, and serve me for a thousand years after your strength is fully restored, I will let you go free and never break my word." ”

Le Kai thought for a while and said, after all, if the strength of the Black Dragon King is restored, I don't know how long it will take, and besides, after the strength is restored, it can still be used for a thousand years to drive himself, and all the capital has been recovered, you know, he is only a teenager now, and he doesn't know how many years it will take for the Black Dragon King to completely recover, maybe he will not be able to recover in this life, even if he recovers, there is still a thousand years of hard work, which is a big profit.

It's just that with such harsh conditions, can such an arrogant guy as the Black Dragon King agree?

"Okay, that's a deal, but in this process, you must not be passive and slack off, if you deliberately delay, won't I never be able to completely recover? How about five thousand years? In five thousand years, you must do your best to help me recover, and after that, I will definitely fight for you wholeheartedly for a thousand years. ”

The Black Dragon King is not stupid, for fear that Le Kai will deliberately delay at the last step, so won't he never have a chance to get out? The Dragon Clan is definitely the race that yearns for freedom the most in this world, they have a perverted desire for the so-called freedom, and they are unwilling to be subject to any restrictions, even heaven and earth!

"Okay, a word is a certainty!" Le Kai was stunned for a moment, and then rejoiced, in this way, the Black Dragon King will follow him for at least six thousand years, this is really a terrifying number, although the Dan idiot master said that the alchemist has won the creation of heaven and earth, and the longevity is far more than that of ordinary martial artists, but six thousand years, it is really too terrifying.

Such a long time is enough to break through and do a lot of things, and at that time, what if you release the Black Dragon King.

For the Black Dragon King, the long life, six thousand years is just a snap of a finger, sometimes they sleep and dormant at a time, they can reach 10,000 years, and they are the longest-lived creatures between heaven and earth.

"Now that you have reached an agreement, you should always tell me now, why are you stopping me from advancing, the incinerator also feels that there is a very powerful treasure ahead, as my natal magic weapon, it cannot harm me. Le Kai looked at the Black Dragon King, full of doubts.

"Le Kai, you are really bold, do you know what this incineration furnace is? The Black Dragon King said coldly, as if he was looking at an idiot.

Le Kai frowned and said, "The natal magic weapon is related to a cultivator's life, isn't it the stronger the better?" Black Dragon King, what do you mean?"
