The hostility of the illusory fire is faint, but it is there.

If it weren't for Wu Hao's own extraordinary sensitivity to the changes in other people's emotions, he might not have been able to notice it.

Wu Yu was a little puzzled and curious, tentatively stretched out his finger and touched it lightly, and a slight burning sensation came.

There was a soft crack, and the illusory fire lit up like a futt, and then extinguished in an instant.

The breath, which was already so faint that it was difficult to detect, disappeared completely, and only a dark red fragment the size of a grain of rice fell straight down.

Huo Yan'er, who was aware of his movements, reached out to catch the dark red fragment and explained, "The free fire element accidentally generated spirituality in the process of converging, and then merged with dust, rocks and other things, and finally turned into a fire spirit. ”

"Fire spirits have souls and no souls, they have no independent consciousness, and they only wander in the place of birth."

Wu Yu thought for a while, and was about to ask a question, only to hear Huo Yan'er throw the dark red fragment over: "The flame crystal fragment, the carrier of the fire spirit spirituality, contains the power of fire with a high degree of purity, which is more stable than the fire magic crystal, and can be melted into a stable Yang Yan Crystal, and can also be used to condense the power of fire." ”

The questions that had just reached his lips were answered one after another before he could speak, and Wu Yu didn't know what to say for a while.

For a moment, he thought that Huo Yan'er had mastered the art of mind reading.

He silently caught the flame crystal fragment, released his perception and swept it, and found that the purity of the fire power in the flame crystal fragment was indeed not bad, and it was a good option to use it to condense the elemental species, but it was a pity that the amount of fire power was a little less.

Huo Yan'er said: "According to the idea of condensing the elemental species you said, it should be enough to use the flame crystal fragments, the characteristics of the flame crystal fragments themselves are very suitable for melting, if the number is not enough, we can collect a little more and melt into the flame crystal." Wu Yu looked at her seriously, and began to wonder if she had really mastered the art of mind reading.

Huo Yan'er didn't seem to notice his strange gaze, and asked, "I just thought of a question, even if you can condense the elemental species, but the elemental crystal ball measures the compatibility of the elements, is your plan really feasible?" ”

Wu Yu was not worried about the question she raised, when he was in Shengyuan Town, he had experienced the test of the Elemental Crystal Sphere, and he could probably guess that the principle of the Elemental Crystal Sphere was actually reflected according to the degree of fusing the power of the elements.

For a normal mystery, the more the power of the reference element released by the elemental crystal ball is fused, the higher the fit, and Wu Yu can use the fire element species to forcibly contain the power of the benchmark fire used for testing, so that he can reflect a certain degree of fire element fit.

Obviously, in this scheme, the higher the quality of the elemental species, the better the effect of containment, because the power of the high-precision and pure elements itself has a certain characteristic of aggregating the same elements and rejecting different elements.

As for how many high-quality elemental species are needed to accommodate 100% success, then Wu Yu doesn't know, so he can only pull it up as much as possible.

However, the above are all the results of Wu Hao's inference based on the information he currently has, although he is very sure, but he does not rule out the possibility of a very small probability of failure, so he did not say it all.

"If nothing else, no problem."

"What if something happens?"

It's not that Huo Yan'er deliberately choked him, Wu Yu's name is now on the list of suspects of the Holy Sect and the high-level of the City Lord's Mansion, and there is only one chance to sign up for the test.

"We'll talk about it then."

Wu Hao's gaze crossed the edge of the first layer and fell to a black dot suspended in mid-air, looming in the heat and firelight.

He could already vaguely feel that the source of the fire was there.

……

In the outer area of the Fire Domain, on the stone wall at the edge of the first layer, Wu Yu finally saw the hanging thing clearly—a magnificent hall.

Ten dark red chains as thick as ancient pythons connected to the bottom of the main hall, and the other end of the chains pierced the stone wall between the fourth layer and the bottom lava field like a spear.

Looking at the hall that was held in the air by the endless heat wave all year round, Huo Yan'er said slowly: "That is the Flame Heart Palace, the cultivation place of the Sect Master and the Great Elder, and it is also the place where the source of fire is sealed now. ”

Wu Yu asked directly, "How do you want to get over?" ”

He didn't hide his intentions, because he had already said it explicitly when he was out of the city, although Huo Yan'er probably only thought he was joking.

Huo Yan'er's eyes reflected the flickering flames: "You can fly over." ”

Wu Yu turned his head and stared at her: "Can you fly?" ”

"I'm kidding you, why are you so serious." Huo Yan'er snorted, pointed to the thick dark red chain that connected the Flame Heart Palace, and said with a smile: "Elders, they all flew over, like us, even if we get permission, we have to climb up ourselves." ”

Wu Yu was silent for two seconds: "What if I fall?" ”

Directly below the Flame Heart Hall and the dark red chains, there was a slow-flowing lava, and there was no place for the entire lava area to settle, and the core area in the center of the lava field was filled with red flames hundreds of feet high that seemed to erupt from the depths of the earth's core.

If one accidentally fell, Wu Yu had no doubt that even a fifth-level peak fire cultivator would be wiped out in the blink of an eye.

Huo Yan'er smiled and groaned: "What can I do, if you climb the Flame Heart Hall without permission, of course you will be killed if you fall." ”

At this point, she paused for a moment, as if to see Wu Hao's reaction, but he just looked at her quietly.

Secretly bored, she pointed to the core area of the Fire Domain directly below the Flame Heart Temple, which was covered in red flames.

"Those who are qualified to climb the Flame Heart Hall will not fall, and if any guy is so unlucky enough to encounter a volcanic tremor, it will help."

Wu Hao's face was strange, he knew that she was referring to the fire phoenix, but he didn't expect that the dignified Zhenzong Xuan Beast would actually take on the work of the security officer.

He fixed his eyes on the core area, but he didn't see any trace of the fire phoenix, and even if he used his pupil technique, he couldn't penetrate the crimson flames.

The power of nature is not something that can be guessed by man.

Wu Yu no longer thought about these things, and began to seriously look at the ten chains.

The Flame Heart Hall was not as simple as a place to cultivate, he could see that this huge Xuan Array, its role was probably to guide and control the power inside the volcano, and the Flame Heart Hall was the eye of this huge Xuan Array, where most of the flame energy was gathered.

Channeling the natural power of the volcano without letting it get out of control is not something that can be done by relying solely on the large-scale, intricately constructed Xuan Array.

After ruling out all possibilities, there was only one answer left - the source of fire was the core of this Xuan Array core.

Only this kind of fire that is a strange thing that is born in heaven and earth can suppress the power of the volcano.
