The flames transformed by the Yang Qi could incinerate the impurities in his body, Fang Yan's qualifications were not very good, if he didn't have this immortal realm system, he wouldn't have been able to advance to the Yin and Yang Realm at the age of nineteen. And after this Yang Fire Improvement Body, although Fang Yan's qualifications have not changed much, he will become a rare fire spirit body, the fire spirit body has an unimaginable affinity for the fire elements in the world, and cultivating the fire system method can do things twice the effort, which is the anti-heaven effect brought by his own qualifications.

"Whew!"

Fang Yan let out a long sigh of relief, a fiery snake erupted from his body, and Fang Yan opened his closed eyes.

"It's so dangerous, I almost didn't make it through." Fang Yan felt the danger before, and Cheng couldn't help but sigh with emotion.

This king of yang beasts can be said to be an ultimate POS in this yin and yang polar realm, and killing it is an unimaginable benefit. In addition to the Zhiyang flame just now, improve the physique and incinerate the impurities in the body. And the even more precious Crystals of the Sun. Refining to the realm of the sun, you can recreate a fire spirit body. This is also a supreme god body, with this fire spirit body, it can be immune to any fire spells, even if it can't, it can also get most of the weakening. Now, Fang Yan had an overwhelming innate advantage in the face of the fire cultivators.

"This king of yang beasts was killed by me, I don't know if there is a king of yin beasts in that extreme yin land." Fang Yan saw that Xiao Hei had devoured the Crystal of the Absolute Yang and fell into a deep sleep, he put it into the pet pen system, and then couldn't help muttering to himself.

"Xiao Hei has been unable to step into that yin and yang realm for a long time, is it because the accumulation of yin and yang qi in his body is not enough!" Thinking that the Night Demon Tiger Xiao Hei couldn't break through for a long time, he also cultivated in this Yin and Yang Polar Realm, devoured too many elixirs and heavenly treasures, and had the Extreme Yin and Yang Qi for him to absorb and refine, I am afraid that even a pig can break through to the Yin and Yang Realm. When I thought of the cave where Xiao Hei once lived, it was to refine a superb spirit stone into a spirit essence for him to absorb. Fang Yan couldn't help but muttered to himself.

As he spoke, Fang Yan swept towards the depths of the Extreme Yin Land. If he wants to confirm the guess in his heart, he will inevitably have to take a trip to the land of extreme yin to see if there is a king of yin beasts in the depths of the land of extreme yin.

In fact, the reason why Fang Yan was willing to work so hard was because of his own reasons, absorbing the Yang Qi of a Yang Beast King. He was still worried that the yin and yang qi in his body would not be able to achieve a balance. If the two qi of yin and yang are unbalanced, they will stagnate when they cultivate, and Fang Yan has a deep understanding of it.

After a day of non-stop flying, Fang Yan entered the depths of the Extreme Yin Land, and Fang Yan found that there was an endless cold pool in the depths of this Extreme Yin Land. The cold air on the cold pool gives people a cold and eerie feeling. If it weren't for Fang Yan absorbing the Yang Qi in the body of the Yang Beast King, Fang Yan wouldn't have been able to get close to this cold pool at all. The closer he got, Fang Yan had a strange feeling that his soul was frozen.

"I don't know if there is a storage of the king of yin beasts in this cold pool." Look at the cold pool that is bubbling cold. Fang Yan's brows furrowed deeply.

"Volcanic Fury!"

Fang Yan let out a loud shout, and the fury of the volcano of his own supernatural power burst out in an instant. A monstrous and huge fire dragon came to life, slamming into the cold pool with its teeth and claws. I only heard a loud bang, the cold pool was splashing with monstrous waves, and as soon as the terrifying high temperature entered the cold pool, in addition to splashing a monstrous wave of water, it quickly returned to calm.

What Fang Yan didn't know was that although this cold pool had calmed down, the capacity of this cold pool had shrunk by at least one foot. The capacity of a huge pool of cold pools evaporated by one foot. It is enough to see the power of this volcanic fury. Its power is two or three percent stronger than before.

"My wise master. Quickly let Xiao Hei out. Fang Yan waited intently, looking at the turbulent lake, and suddenly a slightly rapid voice sounded in Fang Yan's mind.

"Xiao Hei, you are going to make a fuss like that, you just swallowed the Crystal of the Supreme Sun, and now you don't want to retreat and cultivate. What are you going to do out there? Fang Yan asked at the divine thought from the Night Demon Tiger Xiao Hei.

"My wise master, I feel like I'm going to break through." When Xiao Hei heard this, he hurriedly replied to Fang Yan.

"If you want to break through, you can break through, what did you tell me to do?" Fang Yan said a little strangely.

"No, my wise master, listen to me! I found an opportunity to break through. You have to help me, and without you helping me, it would be useless for me to stay in retreat for a long time. Xiao Hei saw that Fang Yan was a little displeased, and hurriedly explained.

"You found an opportunity to break through, could it be related to the Crystal of the Sun?" Fang Yan frowned when he heard this, and asked at him.

"Yes master, I devoured the Crystal of the Extreme Yin, I feel that I am about to break through, but I lack the key Yin Qi in my body, if you kill the King of Yin Beasts in the Land of Extreme Yin and let me devour the Crystal of Extreme Yin, I will almost be able to break through to the Yin and Yang Realm. I am a wise and martial, graceful, handsome and great master, you must help me this time, and the happiness of the second half of my life depends on you. Xiao Hei continued to spread the word when he heard this.

"I see, you come out, I'm looking for the king of the Yin Beast now. You find him, and I'll take care of killing him. The Crystal of Extreme Yin will be given to you. Fang Yan couldn't help but say when he heard this. As he spoke, his mind moved, and then he summoned the little black out of the pet pen system.

"My wise master, you are now in the land of extreme yin, come, you go to rest, look at me, I forced him out of this cold pool." As soon as Xiao Hei got out of the pet pen system, he glanced at the situation around him, and then he looked at Fang Yan with a look of dedication.

"Okay, let's see how you forced this king of yin beasts out." Looking at the little black who looked like a treasure, Fang Yan couldn't help but smile.

"Haha...... My wise master, don't underestimate Xiao Hei, Xiao Hei is not what it used to be. Xiao Hei couldn't help laughing when he heard this. He was devouring the Crystal, and he had undergone a drastic change.

"Tiger roars!"

As he spoke, Fang Yan stepped back, while Xiao Hei walked towards the cold pool with his head held high. He threw his head back and roared, and then a huge ball of flame emitted a scorching glow and shot towards the cold pool.

"Boom!"

I only heard a loud rumbling sound, and the water was raging. What shocked Fang Yan was that the ball of flame shot out by this little black was very domineering, and layers of black flames appeared on the cold pool, and the fire was like a snowball rolling with the undulating waves. The entire cold pool burned, and an astonishing temperature radiated along the surroundings. (To be continued......)
