Feng Xin was stunned for a moment, and hurriedly gave him another metal ball.

Yahan took the silver-white metal ball, and a seeping coolness suddenly came from his hand, looking at the middle-grade fire element that roared loudly, he quickly threw it over without thinking about it.

Immediately afterwards, he picked up Feng Xin, walked a few steps quickly, and then quickly lay on the ground.

The highly concentrated solid nitrogen streaked a graceful trajectory in the air and fell rapidly five meters away from the fire element. It bounced a few times, and then it calmed down completely.

The mid-level fire element hurriedly stopped advancing, watching the metal ball retreat slightly, obviously apprehensive about the terrifying power of this thing.

Ahman waited for a while, but the explosion still didn't come. He got up and looked, only to see that the metal ball was lying quietly a few meters away from the fire elemental, without any movement.

Yahan suddenly realized that he didn't know how to use this weapon at all.

"Is it okay to throw this over?" He asked.

Feng Xin glanced at him angrily, and said angrily: "There is no exciter here, so you must throw it on the fire element, the highly concentrated solid nitrogen will explode when it encounters high temperatures!" ”

"How hot do you need it?"

"Five hundred degrees, the minimum is three hundred degrees Celsius to make him explode."

Yahan almost vomited blood in his heart, there was definitely no five hundred degrees Celsius in that area, and after the ravages of the freezing storm just now, the temperature here had dropped sharply, and fifty degrees was a bit reluctant.

"How many more do you have?" Ahan asked, with a hint of hope in his heart.

"This is the last one, and you've already thrown it away." Feng Xin said weakly, with a hint of confusion in her heart. I got these two prohibited items, and I have used all the relationships and channels of the family, but I didn't expect it to fall short in the end.

"Huh?" Ahan's expression moved, and his eyes burned into the distance.

The mid-level fire elemental saw that the strange thing did not explode like it did just now, and when it came back to its senses, it suddenly became even more angry, and the flames all over its body rose sharply, and a huge roar sounded from its mouth, and it quickly flew towards Yahan.

It's getting closer and closer to the metal ball.

Seven meters, five meters, one meter! Seeing this, Ahan hurriedly fell to the ground, and almost at the same time, the ground shook violently, followed by a deafening loud bang in front of him, and the icy wind raged wildly across the earth.

After a while, Ahan shook off the ice dust from his body and looked ahead.

The red mist in front of it has disappeared, replaced by a thick white fog, and there is a trace of red light flashing in the dense fog, but it is faint and unreal. As for the mid-level fire element, it seemed to have disappeared, without the slightest movement.

"Is it over?" Confused, Ahan got up and walked towards the mist. Feng Xin also hurriedly followed.

Ahan saw that there was no danger, so it was up to her.

Two bursts of highly concentrated solid nitrogen in succession caused the temperature of this area of fire to drop sharply, already below freezing. And the deeper you go, the lower the temperature inside becomes, and from time to time a terrible chill leaks out of the mist.

After walking slowly for a thousand meters, he saw an orange light in front of him. The yellow light appears and disappears, like a heart.

He was overjoyed and hurriedly walked a few steps.

This is the energy core of the intermediate fire element, and the two consecutive attacks have caused it to suffer serious damage, and its huge body has completely dissipated and turned into an energy core.

This energy core was a little smaller than that of the low-level wind elemental, but it was incomparably condensed, and its surroundings were scorching, exuding vigorous heat. It is not dead yet, and for elemental beings, as long as the energy core is not destroyed, it will not die. As long as it is given time, relying on the rich fire system Yuan Power here, it will only take a few years to return to its original state.

But it clearly doesn't have that opportunity.

Yahan hurriedly bit his index finger, concentrated, and quickly carved the blood array contract in the void, and it didn't take long for a faint phantom to quickly disappear into the energy core.

Then his face suddenly turned pale, his body shook slightly, his teeth were clenched, and he was silent.

This time, however, the sharp pain in his mind was much shorter, and just as he was about to endure more intense pain, the pain suddenly disappeared. Compared to the time of the wind elemental, it was a bit short.

There was a hint of doubt in his eyes. I secretly guessed in my heart that this was very likely to be related to spiritual power, the last time I recovered the wind element, my spiritual power was about to be exhausted, so the pain was particularly intense, and it lasted for a very long time. And this time, his spiritual power was not consumed at all, and his spiritual power was full. Even if the other party is a medium fire element, and his strength is far stronger than him, but in terms of spiritual power alone, there is still a big gap with him.

He thought about it for a moment and stopped thinking about it, instead focusing entirely on this orange energy core. Now he could clearly feel that a mysterious connection had been established between him and this energy core.

His original plan was to be satisfied with just recovering a low-level fire element. But he didn't expect him to be so lucky.

How powerful the intermediate fire element is, although I haven't seen its attack, but just the huge size of its body and the raging flames around it when it is in a state of total victory can see its might, not to mention him, even an ordinary chemical level disciple, when he sees such a creature, he will take a detour.

Yahan stretched out his hand and grabbed the orange energy core in his hand, and the scorching heat emitted by the original energy core was quickly withdrawn, and it was incomparably warm in his hand, and it gradually penetrated into his palm and disappeared without a trace.

But then, his face changed drastically, and his body suddenly turned red, exuding a terrifying heat.

It hurts, it hurts!

After the energy core entered the body, not only did it not absorb the yuan power like the wind element, but it leaked a trace of energy. Although there is only a trace of such energy, it is not something that Ahhan can bear. The terrifying energy rushed through the meridians in his body, and for a moment, he felt as if he was being roasted in flames.

He hurriedly closed his eyes and quickly activated the spirit element in his body, trying to digest this terrifying energy. However, the energy of the medium fire element was too strong for a strong person who had just entered the Xuan level, even if that medium fire element was now seriously injured, the light was dim, and he was on the verge of destruction, it was far from something he could bear.

The fiery red spirit element surged quickly in the meridians, and this trace of orange energy was gradually digested by the fire spirit element, and in the blink of an eye, the fire spirit element grew rapidly.

The terrifying heat spreads to the body through the meridians. Dark red blood gradually oozed from the pores of his skin, and at the same time, a trace of hot breath leaked out of it, and from a distance, he seemed to burn a faint flame.

Replaced by an ordinary Xuan-level powerhouse, at such a temperature, the outside is already roasted at this time, and the inside is tender. But since absorbing the liquid in the eggshell, his body has a certain amount of fire immunity, and although this state is painful, he can barely bear it.

Feng Xin next to her looked panicked, and she didn't know what to do, but after more than ten minutes, he still had the same painful expression, and the skin on her whole body did not have any traces of burning, and her heart calmed down a little.

Looking at him sitting upright in the fiery red mist, his hair flying wantonly, he looked like a demon god in flames. Unconsciously there was a trace of awe in my heart.

Half an hour later, the red mist on Ahan's body gradually died down, and the color of his skin gradually returned to normal. He slowly opened his eyes, and in an instant, a red light flashed in his eyes, as if a flame was burning.

He checked the situation inside him slightly, and there was a hint of joy on his face.

After this pain, the fire spirit element in the body grew more than ten times in the blink of an eye, and it was already on a par with the wind spirit element. At the dantian, the two energy cores, one green and one yellow, continued to rotate around the center, and there was no conflict that Yahan had feared.

The fire element, which released a huge amount of energy, faintly shrunk in a circle, and the light dimmed, but fortunately, the rank did not fall. The two energy cores are constantly swallowing the spirit element in the body, and the spirit element seems to become more refined under this entry and exit.

At this time, Feng Xin glanced at Yahan cautiously, and said loudly, "Yahan...... Uncle Shi, since the fire element has been subdued by you, it is better to go to the Chiyan Crystal now! ”

"Well, let's go!" Ahan raised his head and said calmly. He also wanted to see what that red flame crystal was, it was so precious.

The two of them walked towards the depths of the basin, and after this period of time, a faint red mist filled the place again. The effect of highly concentrated solid nitrogen has completely disappeared.

After all, this is a fire system, and the huge fire energy is far from being able to compete with two solid nitrogens.

After walking less than a few hundred meters, a huge fire pit appeared in front of their eyes. The fire pit is dozens of meters in diameter, and the sides are all composed of red flame stones, and the fire snake inside is swallowing and burning, and there seems to be some crystalline things at the bottom.

"Red Flame Stone, here are all Red Flame Stone, this ...... This is the Red Flame Crystal, and the bottom of the pit is the Red Flame Crystal! Feng Xin next to her exclaimed in surprise and quickly ran there.

But soon she stopped, the temperature was quite high, and as soon as she got closer, her hair curled up rapidly.

Ah Han walked a few steps quickly, looking at the fire pit, his eyes flickering, the temperature here even he did not dare to step on easily.

"Uncle Shi, what should I do? We can't even set foot in the temperature here! Feng Xin's face showed a hint of anxiety.
