This Haotian Tower, from the outside, has a diameter of about 300 meters at most, but the interior is a boundary of its own.

Xiang Nan walked into the negative floor and found that there was an open world in front of him, and he couldn't see the edge of the world when he looked at it.

And in this world, there is nothing but some fire pools of different sizes.

These fire pools are strictly regulated in terms of level, from the Quenching Fire Pool, the Innate Fire Pool, the Guiyuan Fire Pool, all the way to the Shenwu Fire Pool, the Semi-Holy Fire Pool, and even the Heavenly Tribulation Fire Pool.

Xiang Nan came to the Guiyuan fire pool and looked carefully, this fire pool was circular, and there was a very strange flame in it, just looking at it, it should be a red liquid.

But Xiang Nan knew that these liquids were actually the flames themselves.

"It's ingenious. Xiang Nan looked at the fire pool and was full of praise, he had very good insight in his previous life, and he also knew that when a high-level martial artist used the power of the sky to compress air, he could compress the air into liquid.

But the flames were also turned into liquid, which was the first time I had seen them in my life.

He first stretched out his hand and paddled the "water" in the pool, and immediately felt a special "aura" that he had never felt before, and this aura, even the dragon blood knife stored in his ring, began to vibrate faintly.

"Is this the energy of the dragon vein? Xiang Nan gasped.

The dragon vein is just an adjective, not something left by the real dragon, but that the dragon vein determines the strength of the aura in one area, and the other side that is not quite appropriate is, the spring.

Xiang Nan touched the "water" in the Guiyuan Fire Pool, and felt warm and suitable, and when he touched the "water" in the Tianyuan Fire Pool, he felt hot and unbearable.

"Perhaps, this is the only time in my life that I have stepped into the Haoran Fire Pool, since I have come here, it is too much of a loss to only cultivate in the Guiyuan Fire Pool. ”

If you only play small, the pattern will be too small.

Xiang Nan gritted his teeth, took off his shirt, and set his eyes on the peeping sky fire pool.

He fished out a handful of fire water from the fire pool, and it didn't feel hot in his hand, which made him feel strange, but when he took it out, his heart chuckled.

The right hand he pulled back, it was actually melted and only Senbai's hand bones remained!

"Oh my God!" Xiang Nan's eyes widened: "I said why didn't I feel hot, it turned out that this fire water directly melted my flesh and blood in an instant." ”

It was only then that a heart-piercing pain appeared.

Xiang Nan broke out in a cold sweat and hurriedly ran the Jiuqing Qiankun Gong to recover from his injuries.

But when the exercises were running, he suddenly found that all the nine fire pools began to glow.

"Oh, I didn't expect that the master still has a hand here. Xiang Nanqi said, he hurriedly used his left hand to fish out the water in the fire pool again, but this time there was a trace of warmth, and then pulled out his left hand, this time his left hand was not melted.

He was in a mood and hurriedly went to fish for the water in the fire pool, and sure enough, the temperature increased, but his right hand still did not melt.

"There are nine fire pools here, and there are nine levels of Nine Qing Qiankun Gong, could it be that there is something hidden in it?" Xiang Nan's heart thumped, he swallowed a mouthful of saliva, and walked to the final Heavenly Tribulation Fire Pool.

He gritted his teeth, stretched his right hand into the Heavenly Tribulation Fire Pool, and felt an unbearable pain coming from his heart, the pain made Xiang Nan drench in a cold sweat in an instant, and he quickly withdrew his right hand, only to find that his right hand was still intact, but it was burned to a translucent color.

This situation made Xiang Nan's heart surging with emotion.

It seems that everyone has selfish intentions, even their own master, Haoran Sect Master!

Unexpectedly, practicing one more layer of Jiuqing Qiankun Gong can correspond to the bearing capacity of a fire pool!

In the entire history of the Haoran Sect, only one of them, himself and the master master, had practiced the ninth level of the Nine Qing Qiankun Gong, so didn't that mean that he could directly enter the Heavenly Tribulation Realm Fire Pool to cultivate?

"If you don't enter the tiger's den, you will get the tiger! Success or failure is here, either death or strength, I will never allow myself to be mediocre in this life!"

Xiang Nan gritted his teeth and jumped directly into the Heavenly Tribulation Fire Pool.

Suddenly, endless pain struck, that kind of pain made Xiang Nan feel that he couldn't survive and die, the key is that this pain not only comes from the pain of burning, but also the pain of extreme cold of the water veins, the suffocation pain of the earth veins, the depletion pain of the wood veins, and the cutting pain of the wind veins.

At this moment, he had an urge to escape, and before his mind could react, his body already wanted to flee the scene.

"No, hold it down, hold it down for me!" Xiang Nan forcibly controlled his instinctive reaction and forced himself into the Heavenly Tribulation Fire Pool.

He lives a heavy life for revenge, if he can't take revenge, then what's the point of living?

If you don't live, you die, and you're not mediocre!

Xiang Nan raised his head and roared angrily, the indescribable pain made him only use this way to vent.

And the most amazing thing is when those fire water penetrated into his skin, penetrated into his body, and even penetrated into his meridians, the spiritual sea.

That pool of fire and water suddenly began to transform, and quickly turned into a pool of thunder and lightning!

"This ......" Xiang Nan's painful forehead was bruised, but he couldn't suppress the horror in his heart.

This vast pool of fire actually changes its attributes according to the talent of the martial artist? That pool of fire and water actually turns into thunder and lightning?

"No, I can't bear it anymore!" Xiang Nan gritted his teeth desperately, and frantically ran the Jiuqing Qiankun Gong.

But Rao is like this, the pain still makes his eyes black, and he feels that he may faint at any time.

If you pass out in this pool of fire, it is really ten deaths, and there is no return.

This is the fire pool cultivated by the Heavenly Tribulation Realm martial artists!

Even Jiuqing Qiankun Gong couldn't suppress the pain that Xiang Nan endured.

"No, you have to refine your body quickly!" Xiang Nan endured the pain that ordinary people couldn't understand, and immediately put the mantra of the golden body into action.

Sixth, the power of the ancient white tiger!

The golden body does not break the mantra of the sixth layer, once it is put into operation, it slightly relieves Xiang Nan of some pain, which shows that this martial art is still effective.

It's just that even if some of the pain is alleviated, the rest of the pain can still torture a person to madness.

In Xiang Nan's mind, there was no distracting thoughts that already hurt, and there was only one thought, that is, refining!

Refining the body! Refining the body! By increasing the strength of one's physical body, one should alleviate the suffering that oneself endures.

The dragon vein qi contained in the Heavenly Tribulation Fire Pool was incomparable, and it almost allowed Xiang Nan to practice the sixth level of the golden body in just ten minutes, and he suddenly gained seven times the strength of his physical body.

At the moment of this sixth success, Xiang Nan was basically about to pass out, but then the seventh mantra began to work, and the pain he suffered was reduced by a point.

Just that bit of pain made Xiang Nan struggle back from the line of death.

The seventh weight, the power of the ancient Xuanwu!

Keep refining!!

In about twenty minutes, the golden body does not break the seventh weight, and it is done!

At this time, Xiang Nan was about to faint from the destruction of the fire pool, and he benefited from the success of the seventh layer, which once again reduced the pain by a point.
