This process is a long process. In a twinkling of an eye, three days have passed. Xiao Yifeng is practicing these three days.

The mysterious fire is also constantly merging and digesting the power of the spirit of the fire, and its breath has begun to continuously improve, gradually releasing a very terrible breath.

Outside the Jiuyan mountain, three days later, Xiao Yifeng hasn't appeared. Many bounty hunters feel that Xiao Yifeng is dead inside and can't come out.

Many people left here one after another. Of course, some bounty hunters didn't leave. They fantasized that Xiao Yifeng came out with red flame fruit.

Maybe at that time, they can grab it, and then take it to replace it.

Mark is here all the time. Liu Xuaner and others are waiting anxiously.

As time goes by, four more days have passed, and it has been a week since the mysterious fire merged with the spirit of fire.

After a week's time, the mysterious fire finally digested the spirit of the fire.

With the help of the power of the spirit of the fire, the mysterious fire burst out with great power. The whole fire released terrible power, completed the final evolution, and evolved into the sky fire at one stroke.

Boom, boom, boom!!!

A roar rang out in the Jiuyan mountain, and then the xuanming fire burst out with great power.

Xiao Yifeng was blown out on the spot, and the whole flame in Jiuyan mountain was absorbed by xuanming fire at this moment, and then merged into one.

The mysterious fire broke out completely, and a terrible blue light burst into the sky, which directly burst the top of the Jiuyan mountain.

The blue light goes straight into the sky, turns into a blue flame and burns the sky, forming a unique landscape. This scene is not only seen by those waiting outside Jiuyan mountain.

The whole area of Jiuyan mountain is thousands of miles away, and many people are rushing to Jiuyan mountain.

If you want to find out what's going on, you can see that there are some miracles in the sky, such as the birth of a treasure or something else. Naturally, it attracts a large group of warriors to Jiuyan mountain.

At the moment, inside the Jiuyan mountain, the xuanming earth fire, no, should be called xuanming sky fire, releasing a tremendous energy atmosphere.

Endless power will be nine Flame Mountain internal to the bang of a mess, the whole mountain are shaking violently.

Xiao Yifeng hid aside and did not dare to move. This evolved into Tianhuo, and its power was really terrible.

This situation lasted for several minutes, and the breath of the dark sky fire stabilized.

Now, the original blue light of xuanming sky fire has become like glass blue. The blue is pure and gives off a holy breath.

Xiao Yifeng calls out the separation, which goes towards xuanming sky fire.

Boom!

Xuanming heavenly fire is aware of the existence of separation and rushes into its body. The blue xuanming heavenly fire is burning Xiao Yifeng's separation and refining its body.

Boom!

Not long after, the realm of separation with the help of the power of the dark sky fire to the spirit of wuchong.

And its physical strength is also rapidly improving under the tempering of this fire.

After a few hours, the dark sky fire on the body melted into his body, and his whole body sent out a very strong breath.

Now xuanming earth fire is transformed into xuanming sky fire, which also improves the fighting capacity of this division.

Moreover, the xuanming heavenly fire and Fenshen are more integrated, and Fenshen can give full play to the power of xuanming heavenly fire.

Now, they practice the poison Sutra separately, control the powerful poison gas, and understand the power of wind. Combined with this mysterious fire, their combat power is directly comparable to the six or seven strong men in the spirit realm.

Put this body away, Xiao Yifeng is going to leave here, suddenly the voice of Xiao Huang remembered.

"Don't go, there's something unexpected!"

"What's the windfall?"

A look of surprise flashed in Xiao Yifeng's eyes.

"There is a hole 100 meters in front of you. Go in!"

Xiao Huang said directly.

Xiao Yifeng's eyes swept towards the front, walked past, and soon he saw a hole, but he didn't know that the hole was leading to there.

Xiao Yifeng's perspective eye swept, but he could not find out the situation at the other end of the cave.

"What's in it?"

Xiao Yifeng asked curiously.

"You'll know when you go in!"

Xiao Huang said.

Xiao Yifeng didn't talk nonsense either. He went directly into the cave and then went down nearly 1000 meters all the way.

It was dark all the way, and soon his eyes were shining, and he found that he had come to another mysterious space.

Here is a sea of flames, and the flames here are more terrible than those in the depths of Jiuyan mountain before.Even Xiao Yifeng felt a very hot breath, as if his body was about to be roasted, but now Xiao Yifeng looked forward.

In the sea of flames, there is a mountain, which is not big or small. The whole mountain is red and burning with flames. It doesn't look like a mountain.

On the contrary, it is a mountain condensed by endless flames, which exudes a very terrible atmosphere, making Xiao Yifeng have a deep sense of oppression, as if this fire is very threatening.

"What is this?"

Xiao Yifeng asked.

"Is this..."

Long Qian looked surprised and hesitated.

"Yes, this is an extremely rare vein of fire, a vein of fire formed by the fire of heaven and earth through more than 100000 years!"

The instrument spirit of Huangtian tower, Xiaohuang said directly.

"Fire pulse?"

Xiao Yifeng's face was frozen.

"The fire pulse contains the unimaginable power of fire, and also contains the profound meaning of the law of fire. If a master who understands the law of fire understands it in this fire pulse," he said

"Or refining the whole fire pulse, his strength will become the title master! Because of the existence of this fire vein, the Jiuyan mountain has been burning for more than 100000 years and has never been extinguished. "

"It is also because of the existence of this fire vein that the spirit of fire and the rare things like red flame fruit are born here. All this is because of this fire vein!"

Xiao Huang said one by one.

"So awesome

Xiao Yifeng looked surprised.

"I didn't expect that there was such a fire vein in the ancient world. I heard the Dragon Emperor say that the ancestors of the fire clan in those years seemed to have got a fire vein, and spent 10000 years refining and controlling it completely, and became the title master at once."

"Even among the title masters, they are the top ones. That's why the fire clan behind was born. It also changed the blood of the fire clan, and made the children of the fire clan behind become the favorite of the flame. They are closer to the flame than ordinary people!"

Long Qian also said.
