Chu Yi actually had the idea of absorbing and refining it the moment he saw the Earth's Heart Fire, but because the situation was urgent at that time, and the wooden dragon was about to absorb FSL, Chu Yi didn't care about it so much.

By the time the battle was over, the Fog Spirit Mountain had been destroyed. The Earth's Heart Fire was also nowhere to be found, and Chu Yi knew that he might have missed this Earth Heart Fire, so he had no choice but to put away this thought.

But at this moment, he suddenly saw the earth-centered fire wrapped in the power of the soul in the Sumeru ring, and Chu Yi was immediately ecstatic.

"Nangong, I originally thought that I wouldn't have a chance to absorb and refine this Earth's Heart Fire, but I didn't expect you to collect it!"

Hearing Chu Yi's voice of surprise. Nangong Yu opened his mouth when he heard this.

"I didn't think about it that much, but at that time you were fighting the wooden dragon, and I just had a chance. I thought that I would collect this inner fire and use it in the future. ”

"Of course you can!"

Chu Yi hurriedly spoke, while his eyes were fixed on the milky white earth core fire in front of him. There was a burst of excitement in my heart.

The fire in front of him, although wrapped in soul power, still exudes a very terrifying temperature.

Even, when Chu Yi's mind was moved and he summoned the fire element he mastered, the fire element didn't even have the courage to get close to the fire in the heart of the earth.

It seems that for the fire element, this milky white terrible earth-centered fire is the king of fire!

Finally, Chu Yi looked at Nangong Yu, his eyes were full of joy, "Nangong." With the presence of the Earth's Core Fire, my elemental power will definitely become even stronger. ”

"After that, even if I fight against a Heaven Rank intermediate powerhouse, I will definitely have a better chance of winning!"

"Since that's the case, I'll absorb this geocentric fire as soon as possible and increase my strength!"

After speaking, Chu Yi immediately summoned the Tower of Babel and immediately entered the tower.

Chu Yi knew very well that fusing the power of the elements was an extremely dangerous process, and if he fused in this room, I am afraid that the entire room would not be able to be saved.

Not to mention, this Earth's Core Fire is an existence that is much stronger than ordinary elemental power!

When he sat cross-legged in the Tower of Babel, Chu Yi immediately took a deep breath. Summoned the fire elemental again.

Having already had many experiences of fusing the power of the elements, Chu Yi knew very well how to fuse it most easily.

It is not the first to merge two diametrically opposed elements, but to merge two similar elements first.

For example, the core fire and the ordinary fire element at this moment.

But after the fire element appeared, I felt the horror of this earth-centered fire, and it instantly became dim, and the flames were dying, as if they were about to be extinguished.

Although Chu Yi was a little surprised, he didn't think much about it, and immediately stimulated the void breath in the depths of his brain, and the power of his soul surged, and after enveloping the earth's core fire and the fire element, he immediately pushed the two towards the middle.

The period was quite smooth, which also made Chu Yi breathe a sigh of relief.

But just when Chu Yi thought that the two would merge when they touched each other, the fire element actually began to churn violently the moment it came into contact, as if it was struggling to escape the soul power wrapped around it. Extremely reluctant to approach this inner fire.

Kindness?!

Seeing this scene, Chu Yi didn't expect it.

Could it be that there is really such a big gap between the ordinary fire element and the fire at the center of the earth?

Just when Chu Yi was puzzled, a scene that Chu Yi didn't expect even more appeared.

This milky white earth's core fire actually showed a little excitement after seeing the ordinary fire element, and it also began to surge, but it kept moving towards the fire element!

Seeing this scene, Chu Yi finally reacted completely, I'm afraid that the gap between this ordinary flame and the earth's core fire is really a world of difference!

And once the gap between the two elements is very huge, I am afraid it will be a little difficult to fuse.

Thinking of this, Chu Yi was a little embarrassed.

If you can't fuse, how can you master this core fire?

At this moment, Nangong Yu's voice suddenly sounded.

"Chu Yi, since it can't be done, it may be feasible to simply manipulate the Earth's Core Fire to devour and replace the ordinary fire element. ”

Heard Nangong Yu's words. Chu Yi suddenly began to get a little excited.

"Great idea!"

And, most importantly, if the core fire is so strong, it will no longer fuse, but will continue to devour.

Does that mean it's going to evolve as well?!

Thinking of this, Chu Yi immediately became excited. He didn't stop the Earth's Core Fire, allowing it to keep moving closer to the fire elemental.

A moment later, in the desperate surge of the fire element, the milky white core fire finally completely touched the fire element.

And at this moment, the fire in the center of the earth suddenly turned into a huge net, directly enveloping the fire element in it.

In an instant, the net contracted, and the Earth's Core Fire actually integrated the entire fire element into its body in an instant.

"Boom!"

"Boom!"

Chu Yi could even feel the impact of the fire element's constant desperate struggle and tumbling in the core of the earth's fire, but the next moment. Everything has turned to peace.

When Chu Yi looked at it, he could no longer see any traces of the fire element, but the fire in the center of the earth seemed to have changed slightly.

After devouring the ordinary fire element, the Earth's Core Fire was originally milky white all over, and at this moment, the inner flame began to have a faint looming blue.

Seeing this scene, Chu Yi immediately realized it. I'm afraid that this geocentric fire has really undergone a mutation after it has been fused!

"Mutation? This is simply constantly strengthening itself and evolving!"

When Chu Yi was shocked, Nangong Yu's voice also sounded in Chu Yi's mind.

"This geocentric fire is obviously something that existed thousands of years ago, I have also heard that the geocentric fire is the king of the fire element, if someone can fuse the geocentric fire when they are on the ground level, then it is definitely the most powerful existence of the martial artist in the same level. ”

"Although we have now broken through to the Heavenly Rank, the existence of the power of the five elements has obviously strengthened our strength. ”

"If we can absorb such an even more terrifying Earth-Centered Fire, we will definitely be able to further our strength!"

"I believe that as long as there is the power of the soul to cooperate with this earth's core fire, even if it is a heaven-level powerhouse, it is definitely not so easy to deal with. ”

"Moreover, if this Inner Fire can really continue to evolve, it is definitely a treasure that is constantly being excavated!"

Nangong Yu's words strengthened Chu Yi's plan to refine this earth's core fire.

"Nangong, you're right, this Earth's Heart Fire is worth far more than any other elemental power to me!"

As he spoke, Chu Yi's heart moved.

"Since this Earthcore Fire is really so powerful, I don't know what kind of changes will occur after fusing with the other four elements. ”

Thinking of this, Chu Yi did not hesitate to summon all the four elements of water, ice, thunder, and earth.

Driven by the power of the soul, in an instant, the power of the four elements immediately rushed towards the fire of the earth's core.

When he was in Moss K before, Chu Yi had also absorbed the fifth element when he had the power of the four elements.

At that time, Chu Yi was constantly refining by fusing them one by one, but this time, Chu Yi knew that with the power of the Earth's Core Fire, he could definitely fuse the power of these four elements at the same time!

Almost at the moment when the power of the four elements approached the Earth's Core Fire, the Earth's Heart Fire suddenly rose up, and the raging flames rose instantly.

In the next moment, the power of the four elements united to pounce on this core fire.

"Boom!"

"Boom!"

"Boom!"

The sound of continuous collision was heard, but let the four elements of water, ice, thunder, and earth desperately impact, the fire in the center of the earth was like an unshakable mountain.

In the next moment, the Earth's Heart Fire violently devoured all the four elemental powers.

Chu Yi looked carefully, and could still see the figure of the four elements that were exactly the same as the fire element.

The next moment, a scene that Chu Yi didn't expect appeared.

He instantly felt that the power of the four elements he had mastered had become meager and meager in his possession.

Could it be that the power of the four elements must also be completely absorbed by the Earth's Core Fire?

Chu Yi didn't think much about it, and immediately a determined look flashed in his eyes.

No matter what, this geocentric fire, you must absorb it!

Thinking of this, Chu Yi immediately began to violently wrap this earth core fire with his soul power, trying to refine it!
