Yun Yu had almost cultivated his internal strength and was going to set off for Purgatory, which was in Huoyan Mountain, far away from Yuntian City.

Huoyan Mountain is located to the west of the Qingyun Empire, close to the border of the Qingyun Empire.

Not wanting anyone to worry about him, Yunyu told them that he had something to do and went out for a while.

Yunyu went to Huoyan Mountain alone.

It's a long way to go to Fire Rock Mountain, and it must be that Edgeworth is faster.

As we approached the Fire Rock Mountain, it was getting hotter and hotter, and I couldn't resist the sword, so I had to hike.

With the blessing of cold and ice energy, if the heat is not good, the cold ice energy will be transported to be lower than the scorching heat.

On the way to Huoyan Mountain, Yun Yu also saw several figures, who seemed to be medicine slaves, and they also came for the fire core.

The fire of the fire core wants the medicine slave to integrate into the body by itself, even if you want to invite someone to help you, you can't do it.

Generally, a high-grade medicine slave must also be a strong man. After all, you need to do a lot of things yourself, and if you don't have enough strength, you can't do it.

This fire rock mountain is too hot, even if it is blessed with cold ice energy, it can't stay for too long, otherwise people are really easy to waste, and they can be evaporated directly.

The more you go into the fire rock mountain, the hotter it gets, and it's really a little unbearable, so you have to lower the temperature of the ice.

The cold and ice form a protective layer that protects the skin from the heat.

When I got to the innermost part of the Fire Rock Mountain, I saw the rock river, which was full of magma, not so much magma as rock water, too thin, like water, fiery rock water.

The fire core is at the bottom of the river in the middle of the rock river, and you have to swim to the bottom of the middle of the rock river to have a chance to get the fire of the fire core.

Looking at the hot rock water, Yun Yu was a little stunned in his heart, if he went down, would it be evaporated?

Yun Yu gritted his teeth and jumped into the rock river, instantly extremely hot, feeling as if his bones were about to be melted by the rock water, it was particularly uncomfortable, and the cold ice strength had reached the lowest temperature.

Slowly swam to the middle of the fire core, dived to the bottom of the river, and found many people, Yun Yu was startled, what is the situation? Are these all medicine slaves who came to get the core fire? No, how can there be so many people.

Yun Yu can't care about it so much, it is important to obtain the core fire, otherwise once the cold ice realm can't cover it, then he will be a dead end, and he doesn't want to die yet.

This is particularly slow to get the core fire.

After a long time, a small flame merged into Yunyu's body, and everything went so smoothly.

Yun Yu was about to leave, and suddenly felt that the temperature of the rock river had dropped a lot, and then he felt that the shaking was more powerful, and the igneous rock mountain began to collapse, Yun Yu was startled, and hurriedly flashed.

Immediately afterwards, many people jumped out of the rock river and fled from the fire rock mountain.

As soon as Yun Yu escaped from Huoyan Mountain, he chased a group of women in black.

I saw the woman in black who took the lead and said loudly: "Hand over the core fire." ”

The work of the core is called the core fire.

Yun Yu said: "Joke, why should I hand over the core fire I obtained with my ability?"

The woman in black snorted coldly: "If you don't hand over the core fire, you won't want to leave alive today." ”

Yun Yu held the Yuntian Blade in his hand and said angrily: "Don't think that if you are a woman, I won't dare to beat you, I will even beat myself if I am ruthless." ”

Yunyu was surrounded by them.

Yun Yu knew that the collapse of this igneous rock mountain was related to his acquisition of the core fire, but if people do not destroy the heavens and the earth for themselves, no matter how important the core fire is to purgatory, since he has obtained the core fire, there is no reason to return it.

The strength of this group of women in black is very strong, and Yun Yu knew that he couldn't bear it, so he quickly took the opportunity to slip away.

Yun Yu wanted to escape, but the woman in black chased after her, and she swore not to give up if she didn't snatch the core fire obtained by Yun Yu.

There are many peaks in the igneous rocks, and although they have not completely collapsed, they are also a mess.

I really couldn't run, Yun Yu stopped, looked at the woman in black who was chasing him, and said angrily: "I said that you guys don't want to get a little core fire, you just chase after you, as if you were being rude." ”

The woman in black who took the lead said: "To be able to obtain the core fire from Yanhe alive, you are also a talent, but the core fire is too important to Huoyan Mountain, if you don't hand over the core fire, we will not give up even if you chase to the ends of the earth." ”

Yun Yu said: "I'll just get a little core fire, is it that serious?"

The woman in black said: "The core fire of the fire core is not missing at all, without the little you obtained, some peaks of the Fire Rock Mountain will begin to collapse, and the demon of the Rock River Seal will also take advantage of this to leave purgatory, if you don't hand over the core fire, it will really be impossible to remedy." ”

Although Yun Yu didn't know what was going on, but it sounded very serious, Yun Yu was a little soft-hearted, and sighed: "It seems that this core fire is indeed very important to you, so okay, how can I return the core fire to you?"

The woman in black said, "If you die, the core fire will naturally return to the fire core." ”

What does that mean? It can't be that Lao Tzu committed suicide himself, right? Is Lao Tzu so mentally retarded?

Yun Yu said: "Originally, I still wanted to return the core fire to you, but if I want to die, this is impossible, if you want the core fire, it depends on your ability." ”

Yun Yu couldn't beat them, so he had to keep running, but Yun Yu's light skills and imperial sword were so good that they couldn't catch up.

If the strength is not good, the ability to run away must be superb, otherwise it will be a dead end.

Yun Yu felt that he was pitted by the ghost doctor, this core fire was very important, he actually asked him to obtain the core fire, and also released the demon in the rock river, he didn't know what this demon was, it seemed that the matter was quite serious.

Yun Yu stopped and talked to them when he was tired of running, and continued to run after recovering his strength, it was impossible for him to die anyway.

Yunyu is not stupid or stupid, how can he casually agree to die, impossible, this is absolutely impossible.

Quickly return the lost core fire, and you can remedy it a little, otherwise you can't remedy it at all.

Suddenly, there were many more people in black cloaks, their hats covering their heads and faces, and they couldn't see their appearance clearly, but the voice of the leader was a little hoarse, "Hand over the core fire." ”
