The ninth style of "Ten Killings of Immortal Phoenix" is called "Purgatory Fire Sea".

This style, the strict requirements for the pure yang true qi in the martial artist's body, as well as the power that can burst out, have a qualitative improvement compared to the eighth type "Ten Directions Divine Furnace".

Generally speaking, even a monk at the first peak of the Demon Tribulation Realm in the middle of the qualification, if he casts the "Purgatory Fire Sea" of the Xiaocheng Realm, he can instantly consume sixty percent of the true yuan in his body. Therefore, although this trick is extremely powerful, ordinary people do not dare to use it lightly.

However, the vastness of Long Haotian's sea of qi is far beyond what people can imagine. At the same time, he also has an incomparably strong recovery power, as well as the support of the double star species, which makes him able to cultivate the "Purgatory Fire Sea" to the entry level in his current realm.

Yan Huang was originally very in awe and curiosity about the last few forms of "Yanque Ten Stages of Killing", especially when Long Haotian taught him the strengthened "Ten Stages of Yanhuang Killing".

And when he heard that Long Haotian had cultivated the "Purgatory Fire Sea" to the entry level, he asked Long Haotian to demonstrate it for him no matter what. The news quickly spread, and everyone made a thirst for Long Haotian.

In desperation, Long Haotian had no choice but to agree. He brought all the people in the inner world to a desert where no one was around. And when Long Haotian completed the demonstration without relying on the power of the inner world, the shocking scene made it difficult for everyone to erase it from their minds for a long time afterward.

If the "Ten Directions Divine Furnace" can turn the earth into rolling magma in an instant, then the "Sea of Purgatory Fire" can completely turn the magma into clouds in the sky.

After that move at that time, a hemispherical crater with a diameter of 100 meters was left on the entire earth in an instant. The blazing breath in the pit could not be dissipated for a long time. And that powerful shock wave directly stunned half of the high-level disciples of the Flame Heaven Realm who had retreated to three hundred meters away. The horror of its power can be seen.

Of course, the cost of completing this demo was enormous. Almost instantly, it drained ninety percent of the true qi in Long Haotian's body. Therefore, in Long Haotian's opinion, this trick must not be used easily unless it is a matter of life and death.

And because the resources were exhausted by Long Haotian alone, the martial arts that others could only temper during this time. After the retreat, everyone made a great leap forward in strength.

When he came to the outer world, Long Haotian immediately got an unexpected surprise.

In his room, there was a set of fiery red armor. Before the retreat, when Long Haotian handed over the sword stone mine to Liu Xuan, he just asked him to build a pair of arm guards for himself. But who would have expected that Liu Xuan would give himself such a huge unexpected surprise.

When Long Haotian and Murong Chen confronted each other, Liu Xuan was not outside. However, he has always been silently watching his good brother in the dark.

When he heard that Murong Chen's persecution and Long Haotian had to fight, he had already decided to do his best to create a battle armor for his brother. In this way, he can protect his brother from deadly calamities in times of crisis.

Long Haotian carefully looked at this perfect set of battle armor, and couldn't help admiring Liu Xuan's ingenious craftsmanship in his heart.

The grade of this armor has reached the eighth order, and both the size and weight are meticulous to the top. Even every finger of oneself can be perfectly integrated with it.

Wearing it, you don't seem to feel it at all. However, you can feel a powerful force guarding you. It's as if a layer of light and tough skin has grown outside of his body.

After a moment of amazement, Long Haotian suddenly discovered a puzzle. That is, the material of this armor seems to be of higher quality than the sword stone mine. You must know that the sword stone mines that he buried under the inner world have not grown to such a point now.

Driven by curiosity, Long Haotian came to the refining workshop in person, on the one hand, to thank his brother, and on the other hand, to ask about the source of this material.

Due to various considerations, Long Haotian has not yet confided the secrets of the inner world to Liu Xuan. And the moment he stepped into the refining workshop, he heard a "buzzing" sound. Following the prestige, Long Haotian's eyes were instantly attracted.

In the backyard of the workshop, a small "volcano" with a height of three meters rose out of thin air. In the past, it was an open flat area. Around this "volcano", there are piles of sword stone mines, like a circular mountain range.

"Brother, what kind of masterpiece are you doing?" asked Long Haotian with a smile.

"If you take a closer look, you'll know!" Liu Xuan smiled mysteriously.

After that, he took Long Haotian to "board" the crater. And Long Haotian came close to see that this was a special furnace artificially built by Liu Xuan.

The crater of this volcano is about a meter in diameter and filled with red-hot gold water. And on that "volcanic wall", Long Haotian was pleasantly surprised to see three iron nests the size of ordinary beehives.

Just as Long Haotian was about to ask, he saw several Iron Hive Red Bees fly out of it, and then flew to the top of the sword stone mine next to the volcano, and began to greedily suck the essence of the ore.

After inhaling the scene for about half a moment, the air was filled with a blazing breath. There were several huge pits left on the ore, and the red bees became much fatter. After that, they flew back to the crater and continued their nesting work.

"Ha! I really didn't expect that those two red bees would have such a scale a month later!" Long Haotian said with great joy. And he already understood at this moment that the set of battle armor on his body was forged from the nest of this iron nest red bee.

"There are now 10 red bees here. However, I'm afraid that this number can only be controlled at the moment!" Liu Xuan had a look of regret on his face.

"Why is that?" Long Haotian wondered.

"Resources are limited," Liu Xuan sighed and said, "At the current rate at which these ten red bees are sucking, the 200,000 jin sword stone mine you gave me can barely last for a month." If there are a few more, I am afraid that within ten days, these ores will be completely drained. And at that point, I didn't have the confidence to control these crazy guys. Once I let them go berserk, I'm really worried that Yanfu will be turned to ashes in an instant!"

"200,000 catties of sword stone mine, will it be consumed in less than two months?" Long Haotian looked at those little red bees, his eyes full of shock. Their appetite is also staggering.
