The temperature around was already very high, so high that when Lin Fenghan had just stepped into the cave, he inhaled the air in his nose, and there was a hot feeling, a burning sensation of skin and flesh.

And at this moment, the Yuanyang Fire Guard that was surrounding Lin Fenghan's neck rose with a soft light, like a barrier enveloping Lin Fenghan's body, from the invasion of high temperatures.

Lin Feng's cold and hot feeling melted most of it, and his wrinkled eyebrows stretched out.

Sure enough, the heat of this second layer is not to be feared at all, and now, the only thing that needs to be worried about is the half-monthly boom.

Thinking of this, Lin Fenghan immediately found a position close to the entrance of the cave, and sat cross-legged with peace of mind, counting the days, in two more days, it should be the moment when the craze broke out, as long as he withstood this craze, he could cultivate on the second layer of this refining treasure cave in the future.

Two days later, he passed by Lin Fenghan's meditation.

Suddenly, the scorching heat of the second layer of the entire Refining Treasure Cave began to surge without any warning.

It's like water that was already boiling, and suddenly the temperature increased by two times, and the sudden change in temperature made the second layer of the Refining Treasure Cave, which was already hot to the limit, completely turn into a hellish pink mist.

Lin Fenghan, who was meditating and meditating, opened his eyes in an instant, and the hot fiery red mist made a trace of pain flash on his face in an instant.

The scorching temperature caused both of his eyes to have to squint immediately to avoid being burned and damaged.

Not only that, but even breathing became extremely difficult, and the red and pink mist inhaled was like a ball of fire, surging in the internal organs.

While Lin Fenghan hurriedly closed his eyes, he had to close his breathing as well, pushing the true yuan to maintain the normal operation of his body.

"The craze is coming!"

Lin Fenghan clearly felt at this moment that this craze was coming so without warning, and where the spiritual sense touched, the surrounding space began to distort violently.

It's so hot!

Lin Fenghan knew very well that he had to leave here quickly, otherwise he would be swallowed up by this heat and incinerated into ashes.

But Lin Fenghan quickly suppressed this urge to leave quickly.

It's not that I don't want to leave, but I can't leave at all!

The surrounding red and pink fog, even if he has the Yuanyang Imperial Fire Suit, he can no longer resist this craze, so Lin Fenghan had to use a large amount of True Yuan to cooperate with the resistance of the Yuanyang Imperial Fire Suit, that is, because of the use of a large number of True Yuan, Lin Fenghan couldn't move half a step at all.

To move is to die, but to continue to resist now, there is still a glimmer of life.

"Hold on!"

Lin Fenghan, who had his eyes closed, raised his eyebrows, and the surging true yuan began to pour into the Yuanyang fire-resisting suit, this fire-resisting weapon made of Yuanyang fire silk and Jiuji'er feathers had already shown its powerful defense for the first time.

Under the urging of Zhenyuan, the Yuanyang Imperial Fire Suit suddenly wrapped itself around Lin Fenghan's neck and fluttered slightly, and the surrounding red and pink mist was once again isolated, even if the fog entered through refraction was within Lin Fenghan's range.

The effect of the Yuanyang Fire Suit far exceeded Lin Fenghan's expectations!

Lin Fenghan finally smiled, the current boom mist generated in the second layer of the Refining Weapon Treasure Cave was completely unable to produce any threat, not only that, but it had become a tool for Lin Fenghan's cultivation.

You must know that this craze is fierce and abnormal, but the heat wave generated by the fire in the center of the earth contains the power of yang fire, and this power of yang fire has extremely great benefits to one of the exercises practiced by Lin Fenghan, the Heavenly Xuanqi Spiritual Technique.

Absorbing and cultivating has gradually made Lin Fenghan's cultivation increase significantly.

Lin Fenghan was still some distance away from the fourth layer of the Qiankun Realm now, and the more he cultivated in the future, the more huge the aura he accumulated, and the total amount of these was several times higher than the original.

Lin Fenghan knew very well that if he came to the craze a few more times, he would definitely be able to reach the fourth layer of the Qiankun Realm smoothly.

It's a pity that the craze appears quickly and disappears quickly.

In just one hour, the craze disappeared without any warning, the red and pink mist also dissipated, and after the power of the yang fire gradually changed back to its normal weight, Lin Fenghan once again entered the state of meditation just now.

Lin Feng said secretly, it's a pity!

If you can soak in the craze all day long, at most half a month, you will be able to reach the fourth layer of the Qiankun Realm.

Only once in half a month, Lin Fenghan could only reluctantly continue to cultivate honestly.

Lin Fenghan was not satisfied, I was afraid that if the other disciples of the Refining Hall heard this, their jaws would fall in shock, and they would scold and not know what to do.

You must know that within the second layer of the Refining Weapon Treasure Cave, even if you are a disciple at the fifth or sixth level of the Qiankun Realm, when you unfortunately encounter a hot wave, you can only resist desperately, and you can't carry out any cultivation at all, even if you refine a superior fire control magic weapon, you can only barely maintain it, how can there be a person like Lin Fenghan, who uses the "Heavenly Mystery Weapon Spiritual Technique" magic technique to absorb yang energy for his own use.

Lin Fenghan's palm was spread out, wisps of fire appeared, and he looked carefully for a moment, and smiled very satisfied.

This time of absorption, the true element has been significantly improved and qualitatively changed, and even the fire control, fire resistance, and the power of the yuan fire have been slightly enhanced.

It can be seen from this that this "Heavenly Mystery Weapon Spiritual Formula" is so magical.

At the same time, Lin Fenghan also sighed at the mystery of Jiu Ji'er, the monster beast, and the feathers that fell off had such a wonderful use, I have to say that it was a very wise move to create a fire-resisting magic weapon, and he really made the right bet.

And just like that, five months passed!

Lin Fenghan, who was cultivating quietly, had already experienced ten booms in succession, and in the fog of the exuberant red and pink of this tenth boom, Lin Fenghan, who was cultivating, suddenly opened his eyes.

At the moment when those eyes opened, a faint fire could be seen, condensing in the eyes.

Lin Feng's cold black hair was constantly fluttering in the air like burning in an instant, starting from the root of the hair, a red face spread upward. In an instant, Lin Fenghan, who had demonic red hair and red eyes, exuded a powerful aura all over his body.

"Roar!"

Lin Fenghan opened his mouth and suddenly raised his head to the sky and let out a roar.

A terrifying True Yuan Force was released ferociously from his body in an instant, and a huge heat wave, accompanied by a sky-high burning Yuan Fire, completely exploded.

"The fourth layer of the Qiankun Realm has finally broken through!"

"Penance in May, it's worth the trip, hahaha!"

Lin Fenghan looked up to the sky and laughed wildly.

Successfully entered the fourth layer of the Qiankun Realm, a complete change has taken place, and the power of heaven and earth has been penetrated for the first time.

With a move, the True Yuan Floating Room has already integrated some of the natural laws of heaven and earth, and with the help of the power of these laws, many wonderful methods are no longer difficult.

Its big has no outside, its small has no inside, heaven and earth are connected, and the magic law is self-contained.

This is the benefit of the last three layers of the Qiankun Realm!
