The flames transformed by the yang energy can burn impurities in the body. Fang Yan's qualifications are not very good. If he hadn't had this fairy world system, he would not have been able to advance to the Yin-Yang Realm at the age of nineteen. After improving the body with the yang fire, Fang Yan's qualifications have not changed much, but he would have become a rare fire spirit body. The fire spirit body has an unimaginable affinity for the fire elements in the world. Practicing fire magic tricks can achieve twice the result with each other. This is the extraordinary effect brought by his own qualifications.

"call!"

Fang Yan breathed a long sigh, and a fire snake ejaculated out of his body. Fang Yan opened his closed eyes.

"It's so dangerous, I almost couldn't get through it." Fang Yan couldn't help but sigh when he felt the degree of danger before.

The king of Yang Beast can be said to be an ultimate pos in this Yin-Yang extreme realm. It has unimaginable benefits to kill it. In addition to the Supreme Yang flame just now improving the physique to burn impurities in the body, there is also the more precious Supreme Yang crystal. Refining the Supreme Yang realm can create a fire spirit body. This is also a supreme divine body. With this fire spirit body, you can be immune to any fire-type magic spell, and even if you cannot get most of the weakening. Now, Fang Yan has an overwhelming innate advantage against the fire-type monks.

"I have killed this king of Yang Beast. I wonder if there is a king of Yin Beast in that extreme Yin land." Fang Yan saw that Xiao Hei had swallowed the Supreme Yang Crystal and fell into a deep sleep. He put it into the pet bar system, and then he couldn't help but murmured to himself.

"Xiao Hei has been unable to enter the Yin-Yang realm for a long time. Is the accumulation of the Yin-Yang energy in his body insufficient?" Thinking that the dark night demon tiger Xiao Hei has been unable to break through, he has practiced for a long time in this Yin-Yang realm, swallowing too many magical medicines and treasures of heaven and earth. With the extreme Yin-Yang energy for him to absorb and refine, even a pig can break through to the Yin-Yang realm. Thinking of the cave where Xiao Hei once lived, it was to refine a top-grade spiritual stone into spiritual marrow for him to absorb. Fang Yan couldn't help but say to himself.

While speaking, Fang Yan rushed towards the depths of the Jiyin Land. If he wanted to confirm his guess, he would inevitably go to the Jiyin Land to see if there was a king of Yin Beast deep in the Jiyin Land.

In fact, the reason why Fang Yan is willing to work so hard is his own reason, which is absorbing the ultimate yang energy of a king of yang beasts. He is still worried that the yin and yang energy in his body will not reach a balance. The yin and yang energy are unbalanced and will stagnate when practicing. Fang Yan has a deep understanding.

After a day of flying, Fang Yan entered the depths of the extreme Yin land. Fang Yan found that there was an endless cold pool in the depths of the extreme Yin land. The cold air in the cold pond gave people a cool and gloomy feeling. If Fang Yan had not absorbed the yang energy in the body of the Yang Beast King, Fang Yan would not have been able to get close to the cold pool at all. The closer he got, Fang Yan had a strange feeling of his soul being frozen.

"I wonder if there is the existence of the King of Yin Beasts in this cold pool." Looking at the cold pool, Fang Yan's brows were deeply frowning.

"Volcano Wrath!"

Fang Yan shouted loudly, and the fury of the volcano in his own creation was instantly blasted out. A ferocious and huge fire dragon was lifelike, and it opened its teeth and claws and crashed into the cold pool. With a loud bang, the cold pool splashed with huge waves. When the terrifying high temperature entered the cold pool, it soon returned to calm.

What Fang Yan didn't know was that although the cold pool had calmed down, the capacity of the cold pool had been reduced by at least one foot. The capacity of the huge cold pool was evaporated by one foot. It was enough to show the power of the volcano's wrath. Its power was 20% or 30% stronger than before.

"My wise and powerful master, let Xiao Hei come out quickly." Fang Yan was calm and looked at the surging lake. Suddenly, a slightly rapid voice sounded in Fang Yan's mind.

"Xiao Hei, you are going to make trouble like that. You just swallowed the Supreme Sun Crystal. Now you don't go into seclusion and practice well. What are you going to come out to do?" Fang Yan asked at the divine thoughts from the dark night demon tiger Xiao Hei.

"My wise master of Shenwu, I feel that I am going to break through." Xiao Hei hurriedly replied at Fang Yan's voice.

"If you want to break through, you will break through. What did you tell me to do?" Fang Yan said strangely.

"No, my wise and magical master, listen to me! I have found an opportunity to break through. You want to help me. Without you, I will be useless even if I have been in seclusion for a long time." Xiao Hei was a little displeased and hurriedly explained.

"You have found an opportunity to break through. Is it related to the Supreme Yang Crystal?" Fang Yan frowned and asked at him.

"Yes, Master, I swallowed the Supreme Yang Crystal and felt that I was about to break through, but the key Yin Qi was lacking in my body. If you kill the King of Yin Beasts in the Extreme Yin Land and let me swallow the Extreme Yin Crystal, I will almost be able to break through to the Yin-Yang Realm. I am wise, magical, suave, handsome, and great master. You must help me this time. My happiness in the second half of my life depends on you." Xiao Hei continued to send a message when he heard this.

"So that's it. You come out. I'm looking for the King of Yin Beasts. If you find him, I'll be responsible for killing him. I'll give you the Extreme Yin Crystal." Fang Yan couldn't help but hear this. As he spoke, his mind moved, and then summoned Xiao Hei from the pet bar system.

"My wise master of Shenwu, you are in the extreme yin land now. Come and rest, look at me, I force him out of this cold pool." Xiao Hei went out of the pet bar system, took a look at the situation around him, and then said to Fang Yan with a treasure on his face.

"Okay, let's see how you forced the King of Yin Beasts out." Looking at Xiao Hei who looked like offering treasure, Fang Yan couldn't help but smile.

"Haha... My wise master of Shenwu, don't underestimate Ke Xiaohei, Xiaohei is now different from the past." Xiaohei couldn't help laughing when he heard this. He was devouring the Supreme Sun Crystal, but he had undergone earth-shaking changes.

"Tiger roars!"

While speaking, Fang Yan retreated, while Xiao Hei walked towards the cold pool with his head raised and his chest raised. He raised his head and let out a angrily roar. Then, a huge ball of flames emitting hot light shot towards the cold pool.

"Boom!"

There was a loud rumbling sound, and the water waves were surging. What shocked Fang Yan was that the flame ball shot out by the little black was very domineering. The cold pool was covered with black flames, and the fire was rolling bigger and bigger like a snowball with the ups and downs. The entire cold pool was burning, and an amazing temperature radiated along the surroundings. (To be continued, please search for Astronomy, the novel is better, updated and faster!
