Feng Xiyue didn't have much to prepare, that is, he made an ice warehouse for Fire Phoenix City, and put more than 100 buckets of frozen water in it, so as to ensure that the water supply of Fire Phoenix City would not be interrupted during the time he left.

Next, Feng Xiyue traveled lightly and went directly to the depths of the Fire Mountain Range from the back gate of Fire Phoenix City. She didn't say hello to Peng Fei and them, otherwise she would definitely be asked long and short questions again, let the eldest brother explain to them.

The Fire Mountain Range stretches for thousands of miles, and its core location is surrounded by strange peaks, and the mountains are very close to each other, and the hundred-mile radius in the center is the forbidden area of life, where the high temperature is enough to melt gold and iron, and no creature can survive there, even if it is an ancient beast of fire attributes, it can't stay for a while.

And now Feng Xiyue is standing on the edge of this forbidden area.

"These mountains are all volcanoes, and I saw at least a dozen craters along the way. Feng Xiyue retracted her wings as she spoke, and the core position could not fly directly into it, but she had to approach slowly like the last time she faced the Supreme Ice Heart.

"Of course, if it could be so hot here. My feeling is clearer, the Supreme Fire Heart is in the mountain in front of me, go and take a look!" Xiao Lian, who was still nervous at the beginning, felt that the treasure was in front of her, and had already thrown her worries out of the clouds, urging repeatedly.

"You are in the gem space, and it won't be your turn to say it's hot......" Feng Xiyue wiped her forehead with her hand and complained: "Now I'm already sweating hot, and the mountain in front of me is also big, climb it little by little and die of exhaustion if you don't die of heat!"

Xiaolian took a moment to say: "If you have the kung fu to complain, you might as well climb quickly, this is what you said you were going to come, what can you do if you climb a mountain~"

"If you have the ability, you can come out and ...... with me"

"No, I don't want to be a roasted lotus. ”

A person and a couple of spirits just climbed the mountain all the way, without the slightest consciousness that they were in purgatory on earth......

There is only this mountain within a radius of 100 miles from the core of the Agni Mountain Range, the material of this mountain is very special, it is composed of a kind of rock that Feng Xiyue has never seen, it is reasonable to say that the temperature of this place is enough to melt any metal and rock, and even further inside can instantly evaporate anything, but this mountain can exist steadily, and I can't help but make Feng Xiyue curious, what kind of material this mountain is.

Feng Xiyue tried to pick out a stone to study and study, but was burned and grinned: "What is the principle? This ground is so hot, why don't I feel anything when I step on my shoes?!"

"Your focus is not right......" Xiaolian said speechlessly: "This matter has been very strange from the beginning, okay, why hasn't your clothes caught fire yet?" I can understand that you are fine, after all, there is the blood of ancient beasts, but why are your clothes fine?!"

"What are you excited about, do you feel sorry that I didn't make a difference......" Feng Xiyue pursed her lips and explained: "From the moment I approached this place, I felt that the Supreme Ice Heart in my body suddenly began to become active, like the excitement of meeting an old enemy, so I guess it was probably it that protected my clothes." ”

"Supreme Bingxin is excited, this is not necessarily a good sign, the two of them are starting to fight each other now, and when they meet each other, they don't know what will happen......" Xiaolian was a little worried.

“...... When the time comes, act on the occasion and be prepared to run away at any time. ”

One person and one spirit were silent, and they all secretly raised their vigilance, but nothing happened along the way, and even the temperature was only slowly increasing, always within the acceptable range of Feng Xiyue, and the difficult situation like last time did not appear, all of which made Feng Xiyue feel faintly weird, but he had already come here, and there was no reason to retreat.

Finally climbing to the top of the mountain, Feng Xiyue was stunned by the scene in front of him: "Oh my God, what a big crater!"

The top of this mountain is a huge crater with a diameter of several thousand zhang!

Feng Xiyue probe looked down, and at a glance, he saw a red crystal shining in the center, presumably it was the Supreme Fire Heart, and below it was a crimson "magma", different from ordinary magma, the color of these magma was frighteningly bright, giving Feng Xiyue the illusion of seeing the bone pool, but the bone pool does not have this terrifying heat.

And what really surprised Feng Xiyue was that on the inner wall of the crater, there were many golden translucent crystals, and they hadn't been evaporated so close to the Supreme Fire Center?!

This thing looks even better than the rocks that make up the mountain outside, and it's definitely a good thing, so you'll have to find a way to get some of it.

Secretly pondering, Feng Xiyue asked, "How should I go down?" ”

"This can only fly down slowly, in fact, even if you fall, it's fine, you have the Supreme Ice Heart, and soaking in magma is similar to soaking in a hot spring. Xiaolian said it lightly.

"Huh, are you sure?" Feng Xiyue couldn't wait to grab it out and throw it down: "This is the magma associated with the Supreme Fire Heart, you go down and soak it for me." ”

Xiaolian was silent.

Helpless against a guy who pretended to be stupid because of his losses, Feng Xiyue spread her wings and slowly approached the Supreme Fire Heart.

Her speed was extremely slow, carefully observing the surroundings, but nothing happened, the Supreme Fire Heart was still shining calmly in place, and the Supreme Ice Heart in her body did not have any further abnormalities, Feng Xiyue finally slowly let go of her heart and continued to move closer to the Supreme Fire Heart.

Just as she came to within the Ten Feet of the Supreme Flame Heart, the raging flames suddenly rose up! The raging flames instantly surrounded her, and it blocked any retreat for her in all directions!

Oops, hit the mark!

Feng Xiyue's first reaction was to mobilize the Supreme Ice Heart Protector, but she was stunned to find that she couldn't move, she couldn't even mobilize her energy, and it was the same situation as last time! Xiaolian fell into a "dead" state again, and the situation had not changed at all compared to before.

How could this be? Could it be that the Supreme Ice Heart was actually suppressed?

Feng Xiyue rolled her eyes with difficulty, trying to see the surrounding situation clearly, at this time, a cold air in her body suddenly rushed up, she who originally had the Supreme Ice Heart would not feel the cold anymore, but now she felt like falling into an ice cave, it was the Supreme Ice Heart erupting at the limit!

Before Feng Xiyue could figure it out, her eyes widened in horror as she saw the Supreme Fire Heart suddenly turn into a streamer of light and rush into her body with lightning speed!
