On the fifth floor of Liuyan Sand, in a stone chamber at the bottom of an unknown earth lung fire pool, Yang Kai looked strange and sat there quietly.

Although he looked exhausted and was about to lose his energy, there was still an unhidden excitement and joy between Yang Kai's eyebrows, and the sacred Yuan fluctuations slowly emanating from his body were clearly a sign of a significant improvement in his cultivation level.

It has been more than a month since he refined Xuanyin Kui Water, and it was not until yesterday that he completed the refining.

He didn't expect that it would take so long, and many unexpected things happened during the refining process.

The ultimate cold power contained in Xuanyin Kui Water is too powerful. The various spiritual herbs I took before, plus the fire at the center of the earth pulled by the two stone piers, could not suppress the coldness of Xuanyin Kui Water, making the two forces in his body unable to balance the cold and hot forces. As a last resort, Yang Kai could only open the restriction of the third stone pier, which would strengthen the power of the fire at the center of the earth a lot.

I originally thought of using the power of the fire in the center of the earth to balance the Xuanyin Kui Water, but I didn't know that after the restriction of the third stone pier was opened, the Xuanyin Kui Water's power was completely suppressed, and the scorching power in my body became strong.

Yang Kai made up his mind and took the second drop of Xuanyin Kui Water. Then he felt helpless to find that the initial situation happened again.

As a result, he opened all the restrictions on the four stone piers, and the firepower from the center of the earth was fiercely drawn, finally barely maintaining a balance between the hot and cold forces in his body.

However, in this way, the risks and tortures Yang Kai suffered almost increased geometrically. During this long month, he wandered in front of the gates of hell several times and almost failed.

The strong body and tough spiritual consciousness played a crucial role at critical moments. Yang Kai had to use a few drops of the strongest golden blood accumulated in his body to repair his own injuries, otherwise he would not be able to persevere and would have been killed by the power of Xuanyin Kui Water and the fire of the earth's center.

Although good things are a lot of trouble, the final result is beyond Yang Kai's expectations.

At that time, Zong Ao praised Xuanyin Kui Water to the rarest in the sky and not on the ground. Yang Kai thought it was so powerful that it had. He originally hoped that he could directly break through to the third level of the Saint King's realm with the help of this refining, and even touch the threshold of returning to the virtual realm. But now his cultivation is only the peak of the two level of the Saint King's realm.

Two drops of Xuanyin Kui Water, so many rare spiritual herbs, and the power of the earth's center fire here, only promoted him to a small level.

Although not much has increased in realm cultivation, Yang Kai has gained something else.

After pondering for a while, Yang Kai opened his hand and a ball of black magic flame appeared on his palm like a burning fireball. The magic flame looked like there was no change from the previous one, but it did not have the aura of alternating between cold and heat, and the coexistence of good and evil. Anyone used his spiritual sense to investigate it, it was just a ball of fireball that looked a bit weird and evil on the outside, without even a little temperature.

But Yang Kai just moved his divine thoughts, and the ball of demon flames emitted a biting cold and cold aura. With a crackling sound, a layer of frost instantly spread out in the stone chamber, with a terrifying posture of being frozen for thousands of miles. Even the stone wall was frozen hard and clattered. The restriction arranged in this stone chamber independently played a protective role, shaking layers of halos, hindering the spread of the cold artistic conception.

Yang Kai's thoughts changed again, and the biting cold and cold buckwheat disappeared, replaced by endless burning heat from the demonic flames. The ice that had previously spread out disappeared in this instant and disappeared. The power of heat was unstoppable. The protective restriction in the stone chamber had no time to react. Suddenly, a crack was cracked and a layer was shattered.

Yang Kai showed a look of satisfaction, and with a gentle snatch, the black ball of magic flames in his hand disappeared.

He also realized that after refining two drops of Xuanyin Kui Water, the main reason why he failed to improve his cultivation level too much was that his magic flame absorbed most of the energy.

When the Xuanyin Kui Water and various hot forces reach a balance in your body, logically speaking, the power of these two conflicts will stimulate your realm to grow wildly, but there is a strange thing like magic flame in your body. It also coexists with hot and cold, so you can accept the effects of Xuanyin Kui Water and those herbs and elixirs to make the magic flame stronger.

The demon flame was just born, and it was a state of coexistence of hot and cold until more than a month ago. It was sometimes cold and sometimes hot. Although it was mysterious and unpredictable, Yang Kai, as the master, could not control its state change at all.

But now, Yang Kai can do this. While the power of the magic flame has been greatly improved, its compatibility with himself has also increased a lot.

In the future, he will face the enemy again. If he wants to be cold, he will be hot. This kind of artificially controlled magic flame is far more harmful and threatening than its own transformation.

Overall, Yang Kai was still very satisfied with this refining. As early as when the magic flame was born, Yang Kai knew that his strange power had strong shaping and growth.

Unfortunately, he has never figured out how to make the demon flame grow, and no one can tell him this.

This time, by chance, he found a way.

As long as the balance between hot and cold can be achieved, an external force can be formed, and the magic flames can be merged, it can promote its growth.

It seems that the remaining Xuanyin Kui Water is not useless, Yang Kai secretly thought about paying it.

He was still thinking about how to deal with so much Xuanyin Kui Water he had. It would definitely not work to sell it out. Everyone knows the principle of guilt of possessing a treasure. It would be too harsh to place it.

But now, Yang Kai has a good idea.

As long as he collects a large number of yang-attribute fire-attribute spiritual herbs, he can even refine Xuanyin Kui Water in second or third degrees, making the power of the demon flame stronger.

Of course, this is just an idea, and it is still unknown whether it can be realized.

If it weren't for time not allowing, Yang Kai would be willing to refine some Xuanyin Kui Water for experiment. Unfortunately, more than five months have passed since he entered Liuyan Sand, and it is not far from half a year. He can only put this idea aside and find a way to verify it later.

He was afraid that he would never find a good refining environment like the ground lung fire pool here in the future. After all, it was not known that it was the year of the monkey and horse month when the Liuyan Sand was opened.

After sitting quietly for a day, Yang Kai recovered, stood up, turned around, took down the four balls of soft light embedded in this stone chamber and threw them into the space ring.

These luminous balls should not be ordinary things. If you take them back and place them in your residence, you can not only calm your soul, but also optimize the environment. Of course, he will not miss it.

After confirming that there was nothing missing in the stone chamber, Yang Kai left and walked out along the long passage.

Soon, Yang Kai left the passage, stood at the entrance of the wall hole, stared at the left wall hole, and a sneer appeared on the corner of his mouth.

More than a month ago, he suffered a great loss under the spirit of the weapon. If he hadn't cultivated the power of space, he would have died on the spot. Now his cultivation level has been improved to a small level, and he has fully mastered the changes in the heat and heat of the demon flames, so he naturally wanted to avenge his revenge.

It is false to have a weapon refining furnace with a weapon spirit. If possible, he naturally wants to conquer the other party.

However, the weapon spirit is not something that is easy to provoke. Even if Yang Kai is a little confident, he has to make a good decision. Moreover, this battle must be decided quickly. God knows when the Liuyan Sand will be closed. Don’t be teleported out when it is difficult to separate the weapon spirit.

After pondering for a long time, Yang Kai then shook his body and rushed directly toward the hole on the opposite wall.

In mid-air, the firepower in the ground lung fire pool below wrapped his whole body, and energy that was so rich that it could be seen from the naked eye burned his body. A layer of magic flame outside Yang Kai's body burned, emitting a biting cold and cold feeling. Although it could not be said to block the scorching heat very easily, it was not difficult.

Yang Kai looked happy and immediately knew that his magic flame had indeed increased its power. The last time he rushed over, he was still cautious and very alert. He didn't expect that he didn't need to care too much this time.

In just a blink of an eye, Yang Kai came to the hole on the left and walked in with a familiarity.

Yang Kai quickly walked through the passage of hundreds of feet. From beginning to end, the spirit of the weapon was unresponsive. It was not until Yang Kai's figure appeared in the stone chamber again that the weapon refining furnace in the center suddenly buzzed, and the surface was red. The fiery red bird screamed sharply, and its elegant body suddenly rushed out from the surface of the furnace.

In an instant, the temperature of the entire stone chamber skyrocketed and turned red.

This weapon spirit is obviously very revengeful. Last time she was escaped by Yang Kai, she was secretly annoyed for more than a month. Now seeing Yang Kai rushing in again without knowing his life and death, she immediately attacked and prepared to teach him a lesson.

This was exactly what Yang Kai wanted. His body shook, and a layer of cold magic flames tumbling. While resisting the other party's burning breath, his hand swayed. He had already grasped a Sky-killing Spear and threw it at the red firebird with all his strength.

The red firebird roared angrily, as if annoyed that he had been underestimated. With a sharp beak, large waves of fire spurted out from his mouth, attacking Yang Kai in a turbulent momentum.

Yang Kai sneered and had no idea of ​​avoiding it. The thrown Spear of Zhu Tian directly broke a hole in the fire wave. At the same time, the spear twisted and turned into a pitch-black dragon with a large dark mouth. A large amount of cold magic fire was sprayed out from his mouth, blocking the heat wave in an instant.

After several battles, Yang Kai had some insight into the use of the art of controlling the Yuan, and could easily control the holy essence he had attacked and turned into various attacks.
