"Woo woo ~ !!" This black pillar of light has appeared, Li Yan immediately felt that the entire space was dark, and then a biting cold came directly, and the next moment, a sound of ghosts crying wolves sounded, and I saw countless humanoid black shadows constantly flying out of the black pillar of light, rushing towards him and the old man with teeth and claws.

Looking at these black shadows, Li Yan trembled, but the old man was not afraid, but roared excitedly: "Hahahaha, in the Xuanyin Cave that has been accumulated for a long time, there are indeed a large number of ghosts, good come, good come, hahahaha." ”

As he spoke, the old man blocked Li Yan's body with an arrow, and suddenly opened his mouth, and a pitch-black breath erupted from his mouth in vain, turning into a huge black head, blocking in front of him.

"Whew!" the huge black head opened its mouth wide, and let out a long, high-pitched howl that pierced the eardrums, instantly muffling out the ghostly cries of those black shadows.

"Hahahaha, after swallowing these ghosts, this seat can recover a few points again. The old man pinched the seal with his hand, and this invisible force immediately poured out of its body, pouring towards the huge head, and then he shouted softly: "Go!"

As the old man's voice fell, the huge head immediately rushed straight towards those black shadows, only to see that the huge head rushed straight into the black shadows, and then opened a big mouth, and all the black shadows that rushed over were immediately sucked into the mouth of the huge head by a huge suction, and they were swallowed up one after another.

Countless black shadows flew out of the black pillars of light, and then they were constantly swallowed by the huge heads, and with the process of devouring. The huge head also became more and more condensed, and the aura emitted was getting stronger and stronger, and at the same time, a pitch-black aura continued to pour out from his seven holes. Gradually, it was enveloped, and this black aura was dark and deep, as if it could swallow a qiē, even light.

Half an hour later, no more black shadows flew out of the black pillar of light, and the huge head in the black mist opened its mouth and sucked all the black mist that wrapped it into its mouth. It showed a hideous face, and its huge face was still humanized at the moment with a look of satisfaction, and a pair of lantern-like eyes flashed with excitement.

"Is that gone?" the old man pouted. Then he waved at the huge head and said, "Okay, since you don't have anything to eat, let's come back!"

Hear the old man's call. The huge head immediately flew back towards the old man. However, as it approached, Li Yan vaguely heard countless screams coming from the inside of the huge head.

"Whew!" After the huge head flew over, the old man opened his mouth to inhale it, and then the huge head immediately turned into an extremely thick black gas, which was inhaled by the old man.

"Hey, hey, hey......" After inhaling the black mist turned by the huge head, the old man's throat suddenly let out an oozing smile, and then nodded his head repeatedly. smiled: "Not bad, yes, this weight of ghosts." It's almost enough to restore a little bit of strength to this work!"

"That...... Old man, what are those black shadows just now!" Li Yan stepped forward and asked in a low voice.

"Those are the souls of people who have grudges that will not be dispersed after death, also called ghosts. The old man turned his head and said, "The Xuanyin Qi is the ultimate Qi of the Yin Qi in the world, and it has a fatal attraction to this kind of ghost, and it is precisely because of the existence of the Xuanyin Acupoint that this number of ghosts will gather here." ”

"Then did you swallow them all just now?" Li Yan asked again.

"Hehe, that's right, I only have divine thoughts now, and I'm very fragile, devouring this kind of thing helps me condense my broken souls, but these are the ghosts of ordinary people, and no matter how much I swallow, I can't compare to the primordial spirit of a psychic realm martial artist. The old man replied.

"Okay, let's not talk about that, now that the ghost has been cleaned up by me, then you are ready to let the Xuanyin Qi infuse your body. The old man waved his hand and said.

"Hmm. Li Yan nodded, and then asked, "But, how do I let the Xuanyin Qi pour into my body?

"Of course not, with your current cultivation, directly absorbing the Qi of Xuanyin is no different from looking for death. Hearing this, the old man said angrily, and then said: "The qi of Xuanyin is the qi of the supreme yin, and what you cultivate is the power of the supreme yang, these are the two extreme differences, once the two touch together, there will only be one result, that is, you are torn apart by the strong repulsive force of the two forces, so if you want to absorb the qi of Xuanyin, you must first close your dantian and not let a trace of power leak in your body." ”

"Well, I see!" Li Yan nodded, sat down on the spot, and then began to concentrate and calm down, restrain his strength, and close his dantian.

Sealing the dantian is very simple, as long as you stop running a qiē exercise, and then disperse the yuan power that is wandering in the meridians of the body, the dantian will be automatically closed, and Li Yan took half an hour to complete this.

"Okay, what should we do next?" After sealing the dantian, Li Yan stood up and asked the old man.

"Next, I will use the formation on this altar to transform the Xuanyin Qi into another form of power, first boiling your physical body, so that your body can adapt to the power of the Xuanyin Qi as much as possible. As he spoke, the old man turned around and walked towards the octagonal stone platform, and then quickly swiped his hands on the inscriptions carved on the octagonal stone platform.

Every time the old man's finger ran over an inscription on the octagonal stone platform, the inscription would light up, and after about a quarter of an hour, the old man stopped his movements, and at this time, at least a third of the inscriptions were lit up on the entire octagonal stone platform.

At this time, the old man straightened up, his hands quickly formed a series of handprints, and then shouted at the octagonal stone platform: "Open"

"Boom!" As the old man's deep shout fell, the octagonal stone platform immediately came out with a roar, and then the inscriptions on the octagonal stone platform immediately burst into a dazzling light, these lights first slowly wriggled and then slowly enveloped the entire octagonal stone platform, and the next moment, the black pillar of light in the center of the octagonal stone platform gradually began to distort, and then quickly faded, and finally changed into the form of a black flame, constantly gushing out from the black hole in the center of the octagonal stone platform.

This black flame was different from ordinary flames, not only did it not have the high temperature of other flames, but it exuded a cold and piercing chill, which looked extremely strange.

"Whew!" After the black pillar of light transformed into the form of a black flame, the old man also let out a sigh, and then turned to Li Yan and said, "Okay, the power of the Yin contained in this form of Xuanyin Qi has been weakened by eight or nine tenths, and then, you can use this form of Xuanyin Qi to refine your body." ”

"How to use the tempering body?" Li Yan was stunned for a moment and asked.

"Nonsense, of course, it's just to go up and let the yin fire burn, hurry up. The old man said impatiently.

Li Yan looked at the pitch-black flames on the octagonal stone platform, gritted his teeth, and then jumped into the flames fiercely.

"Ahh

Now Li Yan has only one feeling in his mind, that is, pain, this pain is not a pain in the body, but a deeper pain, a pain from the soul, and the severe pain makes Li Yan almost faint.

"Hold on, this kind of yin fire can not only exercise your physical body to a great extent, but also make your soul stronger, especially for your origin body, if you can persevere, your qualifications will also be greatly improved, but you have to remember that no matter how painful it is, you can't run the exercises and use the yuan force, because it is not only useless, but it will also cause a riot of Xuan Yin Qi, which will kill you in an instant. The old man said to Li Yan.

"Hey... Hehe, don't worry, I'll stick to it. Li Yan gritted his teeth and laughed stubbornly at the old man a few times, then stopped talking and sat motionless in the yin fire. (To be continued......)
