According to Wu Hao's original immature idea, the so-called elemental species is to find a heavenly material and earth treasure with enough pure elements and stuff it directly into the dantian.

However, when he proposed to implement this plan today, he realized a very serious problem - how to plug it?

You can't open your stomach and stuff the heavenly and earthly treasures into the dantian, so the cyclone will collapse, and the vast majority of the heavenly treasures are not small, not to mention whether they can be stuffed or not, even if they are forced into it, the cyclone must not be squeezed out.

Therefore, his current method is to absorb the fire element in the flame crystal fragment and send it to the dantian with the reverse Xuangong.

Due to his special physique, these fire elements could not penetrate his body, nor could they fuse with the Xuan Qi in his body, which was equivalent to being locked in the dantian—uh, it seemed that he was getting more and more out of line with his original idea.

Wu Hao doesn't care, from theoretical assumption to practical application, there will always be deviations to some extent, which is a very normal thing.

But to be honest, the idea of the elemental species seemed to be very powerful when it was first proposed, but according to Wu Hao's current application method, it was actually not much different from cultivating Xuan Qi, the only difference was that the absorption of Xuan Qi was replaced by the absorption of fire elements.

It's just a pity that his physique rejects the elementals, otherwise he can directly absorb the free fire elements from the outside world, instead of looking for flame crystal fragments or similar fire things like he does now.

After the fire element in the flame crystal fragment was extracted, it lost the support of the elemental power and turned into a pile of particles of different sizes - whether it was a flame crystal, a dark crystal, or a magic crystal, it was essentially the embodiment of the solidification of elements and Xuan Qi, and in the process of evolving the energy state into the solid state, it was inevitable that various impurities would be doped.

Soon, Wu Yu successfully condensed a red fire elemental seed in the dantian.

Even if it was extracted from the flame crystal fragments, most of the fire element still escaped, so this fire element seed was only the size of a grain of rice.

Perhaps because of the Fire Domain, the fire element in the Flame Crystal Fragment was extracted by Wu Yu, and then there was not much doping with the rest of the elements in the process of absorption, so the purity of this fire element species was surprisingly high, and it should not be too much of a problem to be confused by the fit test.

But then, Wu Hao noticed another problem, that is, after locking the dantian, he could no longer use the Xuan Qi wantonly, otherwise the fire element would leak out with the fast-moving Xuan Qi.

According to the speed of reverse Xuan Gong, this ignition element is really not enough for him to squander.

Although it was said that he could have signed up a long time ago, Xuanqi was like money, and he might have to spend a lot of money at any time, just in case, Wu Hao felt that it was necessary to accumulate more ignition elements.

So he said something to Huo Yan'er, and the two continued to move forward.

Seeing that he was almost at the edge of the second layer, Wu Yu noticed that the fire elements around him suddenly became a little strange.

This strangeness does not mean that the elements have changed from calm to active, because the fire elementals in the fire domain themselves are in an abnormally active state, but that some of the fire elements suddenly show a slight unusual change. It's like a bunch of small balls that were originally rolling in a disorderly manner, and suddenly a column rolls in the same direction.

It's kind of like ...... Guiding him in the right direction.

Wu Yu casually looked at Huo Yan'er and found that she was not aware of this abnormal situation.

He pointed to the fire elemental to point him in the right direction, "I feel like there's something over there. ”

"Really?" Huo Yan'er's eyes condensed slightly, and she felt it carefully, and said with a slight suspicion: "There are no special fluctuations, have you found anything?" ”

It seems that this change in the fire element can only be felt by oneself.

"It's just a feeling."

Wu Hao said emphatically: "My feeling has always been very accurate. ”

Huo Yan'er laughed and quipped, "I don't know if your feelings are accurate, I've only heard that women's intuition has always been accurate." ”

After a while, Huo Yan'er watched Wu Yu smash the rock and dig out a dark red ore the size of two heads from it, and fell silent for a while, not knowing if she was doubting Wu Hao's true gender.

Wu Yu shook the dark red ore in his hand: "What kind of ore is this?" ”

"Dark Flame Iron, a rare ore that can withstand volcanic heat, and the chain that connects the Flame Heart Hall is made of this iron ore."

Wu Yu tried it and found that the fire element in the Dark Flame Iron had been completely solidified and could not be extracted.

It was inconvenient to take such a large piece of iron ore with him, and it was not good to use the excuse in his arms to secretly put it in the Empty Source Sword, so he silently put it back, thinking that he would come back to get it when Yongyan was trying...... If only he could have found the spot then.

Just as he was about to continue towards the edge of the second layer, Wu Yu suddenly discovered that after finding the Dark Flame Mine, the fire element had guided him in a new direction.

After using the previous rhetoric, Huo Yan'er found another ore somewhere dozens of feet away.

Forehead...... I want a resource that can be absorbed, and I can't use the ore.

I don't know if he sensed Wu Hao's thoughts, and after the next guidance, he found a piece of Yan Crystal.

It was not the previous fragment of flame crystals that were the size of rice grains and meatballs, but the size of flame crystals that met the standards of the Fire Saint Sect and could be called flame crystals, the size of a palm.

Seeing that Wu Yu was looking for an accurate one with his 'feeling', Huo Yan'er was silent for a long time, and said in a calm and strange tone: "Your perception ability is quite strong. ”

Wu Yu nodded and said, "My perception ability is indeed much stronger than that of ordinary people. ”

This is a big truth, but he didn't say that he found Yan Jing by perception.

Huo Yan'er: "......"

Wu Yu blinked, in fact, he didn't want to hide the truth in this way, but the fire element provided him with guidance, and there was really no way to explain it.

Oh no, it should be explainable, let me try again.

Wu Yu first felt the direction that the fire element had guided him this time, and said silently in his heart: The distance is too far, I want to be closer, and I want something like Yan Jing that can be absorbed.

The column of fire elementals that were rolling neatly in a certain direction shook slightly, and returned to a state of chaotic scrolling.

Wu Yu blinked: Is my request too much?

Forehead...... Like, maybe, maybe, probably, a little bit.

"Let's go to the next floor."

Without guidance, Wu Yu could only honestly follow the original plan and continue to go down.

Huo Yan'er glanced at him and didn't ask why, just answered 'yes'.

After coming to the third layer, they soon encountered a fire spirit with a third-level peak strength.

Fire spirits of this level will not only unleash hostility towards outsiders, but will also take the initiative to attack.

As soon as he felt the approach of Wu Yu and the others, a fireball shot head-on with a whoosh.
