Suddenly, the human emperor qi in Nie Xiao's body ran out by itself, and began to move along the trajectory of the mysterious object.

The speed seemed to be several times faster than the object, and it would not be long before it was close to the object.

"It's now!" Nie Xiao's eyes opened suddenly, and he poured all his strength into the imperial qi of the person who had just wandered out.

"Bang!" I don't know which direction it came from, the human emperor qi was wrapped in a black spar, the spar fell into Nie Xiao's hand, and the human emperor qi also took it back.

"Black Flame Associated Crystal!" Sun Xiaotian's eyes were full of shock.

The small black spar in front of him actually moved him, an old antique.

"What is the purpose of this spar?" Of course, Nie Xiao didn't know this thing, and it was not introduced in the "World View" of Tongsheng Mansion.

"The function of this spar lies in this thing inside the spar. Sun Xiaotian explained: "The reason why it is called the Black Flame Associated Crystal is because it was born with the Black Flame, the Black does not know which world it came from, and it does not know where it will return, in all the historical records it is a mysterious and particularly terrifying thing, it is a huge evil flame, and the thing contained in the Black Flame Associated Crystal is the Associated Black Flame, you can understand it as the brothers and sisters born when the Black Flame was born." ”

"Brother and sister, does this thing have a gender?" Nie Xiao was a little surprised, it was the first time he had heard that a treasure had a gender.

"I'm just making an analogy, and that's how you can understand it. Sun Xiaotian gave him a blank look.

"So, shouldn't this thing be very dangerous? The black flame is going to burn out the flames that the whole world will not extinguish. Nie Xiao thought about it for a while, and suddenly felt that the thing in his hand was like a timed **.

"If you leave it alone, this associated black flame doesn't know which space it will move to, but now that you have been caught, and you have someone who is emperor, that's another way, you can domesticate it. Sun Xiaotian analyzed.

"Domesticate?" Nie Xiao's mouth is open, can this thing still be domesticated?

"That's right, didn't I say it, it was also born with Black Flame, but now it doesn't contain any attributes and will, which means that it is just an empty energy, if you can use its power to your advantage, then your cultivation will improve by leaps and bounds. Sun Xiaotian looked at Nie Xiaodao.

"Is it really that strong?" Nie Xiao didn't believe it a little, such a good thing can't just be domesticated with human emperor's spirit.

"Of course, this is not a very easy thing, otherwise there would have been ancient powers to do this, and it would have been your turn, the great world of stars in ancient times was not as good as it is now, and the strange treasures at that time came out, and many great powers were born at that time. Sun Xiaotian glanced at Nie Xiao.

"So what are you going to do?" Nie Xiao's curiosity was hooked by Sun Xiaotian's words, the ancient power has not been achieved, if he can do it, wouldn't it prove that his strength has surpassed the ancient power?

"This matter also depends on chance, since your human imperial qi can find its traces, it means that there is still some kind of connection between them, and judging from the brilliance that entered your mind before, it seems that there are other sources in it, maybe your human imperial qi already has the ability to tame the accompanying black flame in it now, but you haven't discovered it. Sun Xiaotian pinched his chin, as if he was thinking carefully.

"Then I'll try it now?" Nie Xiao said as he prepared to inject the Emperor's Qi into this small piece of black crystal.

"Don't act recklessly!" Sun Xiaotian shouted, and Nie Xiaotian stopped what he was doing.

"Then what should I do now? Collect it in the space bag and think about it in the long run?" Nie Xiao was confused by Sun Xiaotian.

"You are now carrying the Black Flame Associated Crystal, which is very similar to the aura of the Black Flame, if you don't dissolve him into your human imperial qi, wherever you go, there will be cultivators who will notice you, and if you are surrounded and killed by many masters at that time, then you will have lost all your previous achievements. Sun Xiaotian said.

"Isn't there a solution?" Nie Xiao is depressed now, this is not good, that is not good, this treasure is still a troublesome thing when he gets it.

"Cultivating babies in the world starts slowly, step by step, your current human imperial qi is like this relationship with this associated black flame, so what you need to do is to use the human imperial qi to slowly lure the associated black flame into the human imperial qi, so that your human imperial qi will gradually grow. "Sun Xiao Tiandao.

"This is easy to do, the human emperor qi and I have the same mind, as long as I inject the human imperial qi into it, I can know the situation. After that, Nie Xiao carefully injected a trace of human imperial qi into the black spar, and then felt that the black flame actually took the initiative to get close to human imperial qi.

This made Nie Xiao overjoyed, so that he could successfully absorb this black flame.

Suddenly, Nie Xiao felt that his entire body was burning like fire, and his bones were about to melt.

"Tell you kid not to be reckless, now this companion Black Flame is going to burn you to ashes with an evil aura!" Sun Xiaotian shouted, very anxious and there was no way to do it.

Nie Xiao didn't expect the change to come so quickly, but now he had no other choice, after guarding his mind, he used the human emperor's qi to forcibly devour Hei Yan, Hei Yan was desperately struggling, the more he struggled, Nie Xiao's body gradually melted, and it seemed that it would soon turn to ashes.

"Xuanhai Qing Qigong!" Nie Xiao gritted his teeth, and a cool breath hit his heart, and a stream of water vapor began to be generated in his entire body, resisting the burning of the black flame, although it was not a real fire, but as long as it could cool down, it could suppress the destruction of the black flame on his body.

After ten breaths, there was no longer any water vapor in Nie Xiao's body, and the fierce black flame disappeared, replaced by a powerful aura that erupted in Nie Xiao's body.

Then Nie Xiao felt that all his meridians were expanding, and the fifty-first qi was quickly formed in the dantian, then the fifty-second dao, and then the fifty-third dao...... It wasn't until fifty-six qi that it slowly stopped.

But the whole process made Nie Xiao feel the pain as if he was in purgatory, and after completing the breakthrough in cultivation, Nie Xiao did not have the slightest sense of strength, but turned pale and fainted.
