The space on the second floor didn't seem to need to be supported by Xiao Xuan's Xuan Qi, and the entire space was endless. And there are mountains and rivers and Gobi in it.

It's just that there are no signs of life except for the small medicine.

Soon Xiao Xuan followed Xiao Yao to a small valley.

As the mountain descends, there is a small lake underneath. But the small lake is half red and half green, which is weird.

"Master, the Yin and Yang Flame is under this lake, but you have to let your body enter this Red Bone Demon Chain. ”

"Can my body come in too?"

Xiao Xuan was shocked.

"Of course you can, the master opened the second layer in surprise, this is not like the first layer where the little spirit is located, only the soul body or consciousness can enter, you can see if you look at me, don't I know it, isn't it the body?"

Hearing Xiao Yao's answer, Xiao Xuan realized that this was indeed the case.

In the first layer, the small spirit spirit is the soul body, while the small medicine in the second layer is the entity.

Xiao Xuan hurriedly asked, "How do I get in?"

"Bastard master, you are really stupid, you are the owner of the red bone demon chain, do you want to come in yourself?"

On the side, Xiao Lingling said sarcastically.

And Xiao Xuan didn't care, and his mind moved directly, and Xiao Xuan's figure in the cultivation tower disappeared on the spot. And on the second layer of the Red Bone Demon Chain, Xiao Xuan's body appeared beside Xiao Lingling and Xiao Yao.

After Xiao Yao explained some details of refining the fire, Xiao Xuan jumped into the lake.

Xiao Xuan knew that he would need a lot of Xuandan in the future, and with the improvement of his realm, the Xuandan he needed would be more advanced, and if he could refine the Xuandan, it would be much easier. Moreover, the Xuanshi and other aspects can also save a lot, after all, the development of the Netherwolf Clan also needs an astronomical amount of Xuandan.

Xiao Xuan continued to dive, and the two forces of cold and hot under the ground continued to increase. If it weren't for Xiao Xuan's strong body, I'm afraid it would be difficult to get close to that yin and yang fire.

Soon Xiao Xuan arrived at the bottom of the lake, and the bottom of the lake is not big, not far in front of Xiao Xuan, there are two small flames, one green and one red, that are intertwined with each other and constantly rotating.

The coldness emanated from the cyan flame, and the scorching energy was of course emitted by the red flame.

Xiao Xuan knew that this was the so-called yin and yang fire.

Don't look at the cyan flame exuding a coldness, but Xiao Xuan knew that it was a kind of cold fire, and it was also a kind of warm fire.

It's cold outside, but it's a gentle flame inside.

Xiao Xuan directly made two marks, which were respectively printed on the two flames. Soon the two flames floated to the palm of his hand, beating happily as if they were two children.

And the mark made by Xiao Xuan is a method of refining fire passed down by his master, which naturally has magical power, otherwise if you want the fire to form an induction with Xiao Xuan so easily, dream about it.

The birth of every fire is an extremely harsh condition, and how can it be refined so easily.

With his own master's method, Xiao Xuan's refining of fire will of course be much simpler.

Xiao Xuan sat cross-legged and slowly closed his eyes, the yin and yang fire in his hand had quickly penetrated into the dantian of his abdomen.

And the first thing Xiao Xuan had to do was to open up a place in the dantian to accommodate the fire, after all, this thing could not be connected with the Xuanqi meridians at this time, otherwise his own meridians would be burned by this thing. Although the fire has been marked by Xiao Xuan, it has not been refined after all, and the power of its flame itself is not something that the meridians can withstand.

When Xiao Xuan really finishes refining the fire, he will not be able to cause harm to his meridians.

It is not difficult to open up space in the dantian.

In just half a day, a space was formed, and the yin and yang fire had been introduced into that space by Xiao Xuan.

The soul power in the body gradually sank into the body, and after coming to the dantian to observe that the yin and yang fire did not repulse, and there was no imbalance, he began to refine it according to the method that Xiao Yao said.

With the operation of the refining method, the yin and yang fire at the dantian quickly rotated, just in case, Xiao Xuan's soul power continued to surround the dantian, and the situation was investigated at any time.

And with the rotation of the yin and yang fire, the Xuan Qi in Xiao Xuan's body, and even the blood, began to boil. At the bottom of the lake, Xiao Xuan's face turned red. As time passed, even the surrounding lake began to boil.

The rotation speed of the yin and yang fire in the dantian is getting faster and faster, and with the continuous rotation, the energy of the two colors of blue and red is slowly born, filling the dantian space opened up by Xiao Xuan, and there is no trace of energy emitting the dantian space.

Under the inspection of the soul power, the cyan and red energy in the dantian became more and more intense, and the color was getting darker and darker.

When the color was intense to a certain extent, the cyan and red energies began to separate, occupying half of the dantian space respectively.

There is a balance between each other.

Seeing this, Xiao Xuan was slightly relieved, but he still didn't dare to relax his vigilance, because the refining was not finished yet, and not only that, but it had reached the most critical step.

That is to convert two fires into flame energy.

Soon, some microparticles began to be born in the two-color energy that was divided into two parts, and if it weren't for Xiao Xuan's strong soul power, it would not have been possible to detect it at all.

I saw that there were more and more microparticles, and in the blue and red two-color energy, it seemed to form a little dust-like two-color microparticle energy.

And as they appeared, the blue and red sparks also separated, interspersed with another energy particle.

And this happened to form a Tai Chi pattern in Xiao Xuan's dantian, and the blue and red tinder became a fish's eye. As the so-called harmony of yin and yang, there is yin in yang, and yang in yin, and mutual checks and balances.

And this is the method that Xiao Xuan's master has found.

Xiao Xuan used the power of his soul to look at the fire formed in the dantian, and his expression was excited.

From then on, he could not only refine Xuanbing, but also Xuandan. On this Xuanyue Continent, Xiao Xuan is definitely the only one.

He believed that the method that Master Zun had come up with, in the entire continent, whether it was Xuan Xiu, Xuan Demon, or other races, no one else would be able to complete it.

Xiao Xuan didn't know where his master found this yin and yang fire, but Xiao Xuan knew that the birth of a single fire was already very harsh, and the birth conditions of such a mutual fire would not be so simple.

Xiao Xuan silently thanked his master in his heart, if it weren't for his master who had already found a yin and yang fire, I am afraid that Xiao Xuan would be able to have his own fire, and I don't know what year and month it was.

Soon Xiao Xuan broke through the water.

"How?"

Xiao Lingling couldn't wait to ask. And Xiao Yao was already looking at Xiao Xuan expectantly.

Xiao Xuan didn't speak, stretched out his left palm, ran the Xuan Refining Record, and a cyan cold flame burned out from his palm. Also stretching out his right palm, a scorching red flame appeared.

Looking at the two flames in Xiao Xuan's hand, one green and one red, one cold and one hot, Xiao Lingling and Xiao Yao were very happy.

Xiao Xuan was also using the flame for the first time, and of course his curiosity was overflowing, constantly playing with the flame in his hands.

"However, the power of the flame does not seem to be strong, according to the records of the Xuan Refining Record, the power of the two flames now, at most, the degree of refining the Xuandan of the middle grade of the ground level, and the level of the Xuanbing of the middle grade of the ground level, if you want to refine the Xuandan or Xuan Bing of the higher level, it will take a long time to make your fire grow. However, this method is too slow, and the quicker way is to devour other high-level fires and nourish your own fires, but the difficulty is not ordinary. ”

After all, if you want to integrate into a higher flame again after forming a flame seed, you need not only opportunities, but also means to reach the sky.

As for the means, Xiao Xuan was not worried, after all, his master had left a lot of experience and methods. He believed that as long as his strength was enough, he would definitely be able to refine a higher-level fire.

And there are many successful cases on the mainland. After all, some high-level fires are not something that anyone can refine. Not everyone has the opportunity to meet it.

The so-called Xuandan Master or Xuanbing Master is not the process of refining fire, but the fire is difficult to find, just like Master Han, although he has a good talent for refining, he couldn't get the fire when he was young, which leads to the fact that he can only use ordinary flames now.

But even so, it is still a Xuan soldier who has refined the lower grade of the ground level, which shows his talent.

Therefore, it is even more difficult to become a high-level Xuandan Master or Xuanbing Master.

Whether it is a Xuandan division or a Xuanbing division, if it is refining some human ranks, then ordinary flames or earth fires are enough, and this is also common to the Xuandan divisions or Xuanbing divisions at the bottom of the Xuanyue Continent.

As for Xiao Xuan, he was already past the age of being able to plant fire, but the method created by his master was different from the method of planting fire on the Xuanyue Continent.

The common method on the mainland is to take action in his dantian, family or sect predecessors when he is young, and forcibly fuse the fire. Then, for years to come, let it resonate with the host, so that the host can control the fire to form a flame.

Xiao Xuan's method is that there is no need to integrate the fire with the dantian, but to forcibly open up a space in the dantian, and refine the two kinds of fire in a specific way, so that the two fires with completely different attributes form a state of checks and balances.

The former is like the relationship between the host and the fire, and more importantly, it borrows the power of the fire.

The latter, however, completely refined the fire for his own use.

The difference between the two is self-evident, and the latter definitely surpasses the former in terms of handling.

In this regard, Xiao Xuan was already impressed by his master who had never met. You can think of such an operation against the sky.

He wondered if his master had learned it from other universes.

After all, a person himself is already very rebellious, but it has to be doubtful to do things against the sky in other fields.

But no matter what, Xiao Xuan has now controlled the yin and yang fire.

Although he has not yet tried to refine soldiers or alchemy, Xiao Xuan believes that as long as time passes, he can refine a mid-grade Xuan soldier of the ground level.

As for improving the level of the tinder, it is purely a matter of chance, and your own strength must also be reached, otherwise even if the tinder is found, the strength is not enough, and it will be 100% eaten by the tinder.

This time it was because the Yin Yang Flame had weakened a lot after years of consumption, and his master had probably done something to the Yin and Yang Flame, otherwise Xiao Xuan believed that he would never be able to refine the Flame so easily.

Soon Xiao Xuan put away the flame in his hand, left Xiao Yao and Xiao Lingling, and returned to his body, anyway, Xiao Lingling and Xiao Yao will not be bored anymore if they have company.

As soon as Xiao Xuan opened his eyes, two flames, one green and one red, appeared in his hands, constantly beating.

Immediately, a smile leaked from Xiao Xuan's face.
