The secret realm also belongs to a kind of Xiaoqian Shijie, but it is just a relatively small Xiaoqian Shijie.

After entering the secret realm, the temperature around Chu Hao immediately made Chu Hao feel a significant change, and there were countless heat waves rolling towards him, Chu Hao immediately cast an ice heart spell to block these heat waves.

In fact, with Chu Hao's current cultivation, the ordinary heat already made him feel nothing, but the heat in this secret realm was like a big simmering furnace, extremely clear.

Where does this heat come from?

After casting the Pure Heart Mantra, the heat was not obvious, but Chu Hao was still curious. Speaking of which, it was the first time he had entered such a place as the Secret Realm. Although the previous Liutian Ruins were an independent Xiaoqian Shijie, it was at most a relatively low-level dangerous place, and it was much worse than the secret realm naturally formed by heaven and earth.

The Hongtian Secret Realm belongs to a secret realm with a very strong fire attribute of the Five Elements, and there is no sign of any flames around, nor any burning objects, but this temperature alone is much higher than the outside, and I am afraid that the monks of the Jindan period will also be uncomfortable in it.

Chu Hao's divine sense swept away, and everything in the entire Hongtian Secret Realm was covered by his divine sense, - the entire secret realm was not big, and it could be completed in about a minute. The yang energy here is full of energy, and the fire attribute is bursting, so it stands to reason that even if there is nothing, it should be suitable for the cultivation of the cultivator of the fire spirit root.

After all, in the unique environment, the degree of aura determines the speed of cultivation, but the relative nature of attributes is also extremely critical, just in terms of the speed of cultivation, the secret realm suitable for each attribute is more refined than the cultivation of aura.

It's a pity that the Hongtian Secret Realm seems to be too low-level, Chu Hao belongs to the Heavenly Spirit Root, and it is the most Haode Spirit Root under the superb Spirit Root, which contains the Qi of the Five Elements, and can be absorbed and cultivated. However, in this Hongtian Secret Realm, Chu Hao still couldn't feel any breath that could be absorbed, except for an unbelievably high temperature, it didn't help him at all.

"Even if the transformation of the out-of-body period is carried out here, presumably Old Man Bai Yun will not dare to try it. Chu Hao thought in his heart, originally he had great expectations for the secret realm, but the greater the expectations, the greater the disappointment, the whole secret realm didn't know what it was like before, but now in Chu Hao's opinion, it was just a wasteland, except for being full of dirt and heat, it had no effect.

"I now have the natal primordial infant and the earth-attribute primordial infant, since I have come, I can't come in vain, three medium-grade spirit stones, Lao Tzu didn't even think about it in the second heaven. Chu Hao felt sorry for the three high-grade spirit stones, he originally planned to go out like this, but he was very unwilling, after his divine sense inspected for a long time, he still decided to sit down on this red soil, and then closed his eyes and meditated, running his own exercises.

However, the two primordial babies in their bodies were quiet, and they didn't react at all to the heat wave around them like magma, and Chu Hao's qi and blood also had no resonance, the aura here was extremely low, except for the fire attribute was more ferocious, the other four five elements were actually thin to the extreme.

For any exercise, there is no improvement effect.

Even if it is a pure fire attribute supernatural power, but the cultivator's exercises also need the other five elements to complement each other, there is no doubt that Chu Hao's three medium-grade spirit stones are in vain.

Half a day later, the unwilling Chu Hao finally opened his eyes, with a wry smile on his face. There is no miracle at all, this place is really a wasteland, and it even makes his Tu Yuanying feel a little unbalanced, wrapped in a heat wave, and the whole person seems to be boiling.

"Fooled. ”

Among the secret realms and dangerous places given to him by the Great Elder, except for the "Gravedigging Dangerous Place", which was a dangerous place that the Giant Wood Immortal Venerable had once mentioned, Chu Hao chose the Hongtian Secret Realm and the Zhongnan Secret Realm after passing his own screening, but he didn't expect that the first secret realm made him extremely disappointed. But think about it, this secret realm has existed for so many years, and it is still used as a tool by Qinghongzong to earn spirit stones, even if there were some superb fire attribute spirit stones, or spiritual objects and the like, they should be almost found.

"Let's go. There was nothing to gain in a day, and Chu Hao was no longer attached, but just as he was about to leave, a wave of heat hit him again, and Chu Hao impatiently cast an ice heart spell again to block the front.

But at this time, Chu Hao had an idea!

Where did this heat wave come from?

From entering the secret realm to the present, Chu Hao has also asked himself several times, but he has never paid attention to it. After all, the Hongtian Secret Realm is famous in the Heavenly Demon Mountain Range for missing four of the five elements, and the fire attribute is fierce. Chu Hao only thought about it at that time, and didn't dig deeper!

But this heat wave was like cold water, which directly woke Chu Hao up, - yes, where did this heat wave come from?

The heat wave exists in the entire Hongtian Secret Realm, but where exactly it came out and in what form it appeared, I am afraid that among the monks who entered the Hongtian Secret Realm and found nothing, none of them would delve into it!

After all, a monk who has reached the Yuan Infant Stage can completely cover all the situations here with a single divine sense, and no corner is an exception! Heat Wave? Isn't this place with a fierce fire attribute? Who cares so much?

But Chu Hao was different, when he left, this heat wave suddenly made him sober up a lot, and he began to think deeply.

Heat waves usually come and go, and the temperature of the entire secret realm is very high, and suddenly there is a heat wave, and suddenly the heat wave dissipates. If you attribute everything to the fire attribute here, it seems to make a lot of sense.

But Chu Hao just didn't want to think like this.

Any heat and breath here is attributed to the abundance of fire attributes, which seems to be very easy to understand, but the secret realm is originally an irregular place naturally formed by heaven and earth, it can be said that the laws here are different from the outside, if you understand it with the common sense of the Nine Heavens, then the secret realm has no reason to exist!

Existence is truth!

Chu Hao is convinced of this!

These heat waves appear out of thin air, and they are definitely not as simple as they seem!

I have to say that Chu Hao has begun to drill the horns, the Hongtian Secret Realm has existed for hundreds of years, and there are not many monks who have entered and exited, and there are also a lot of great powers in the Yin and Yang Period, but they are all empty-handed, and none of them have been discovered. And basically, the other secret realms of the Heavenly Demon Mountain Range seem to be the same situation!

When it first came out, it was very fresh, but it was almost uniform, and no one found any treasures in it, it was completely a gimmick of the secret realm, a piece of wasteland!

And Chu Hao also didn't find anything in the Hongtian Secret Realm, but because of the unusual nature of this fire, Chu Hao couldn't think about this matter with directional thinking!

Their laws are different!

So, Chu Hao recognized this and began to explore again in the entire secret realm.

One-day ...... Two-day ...... Three-day ......

For seven days, Chu Hao's divine consciousness had not been withdrawn, feeling the frequency of heat waves, looking for patterns.

But unfortunately, it seems that there is no pattern at all in the heat wave, and although Chu Hao is aware that this heat wave seems to be coming from under the ground, but under the cover of his divine sense, there is neither lava nor flames below, which is very strange!

Seven days, wasted again!

However, this situation did not disappoint Chu Hao like he did on the first day, but he was even more emotional, full of enthusiasm for exploring the secret realm!

"What is wrong?" Chu Hao thought to himself, gathering his divine consciousness again and burrowing into the ground of the secret realm. The ground of the entire Hongtian Secret Realm was a fiery red land, and this demonic mud covered the entire secret realm. The bottom is not deep, because it is naturally formed by heaven and earth, there may be some laws below that are detached from the common sense of the five elements, and if you explore it rashly, your divine consciousness will be greatly affected, and even your life will be in danger. Chu Hao knew this common sense, so he didn't dare to go too deep.

And just this time, when his divine consciousness entered the ground, Chu Hao's heart was suddenly touched by something, and the next moment, a heat wave that was more fierce and hot than any previous one hit him like a raging tide!

Chu Hao's face was not surprised, he immediately used a spell barrier to isolate the heat wave, and then continued with his divine sense again!

"You...... Stop!"

At this time, countless waves of fire were coming towards Chu Hao, this time the secret realm was like a Dan furnace being urged, as if there were flames beginning to burn in all directions, and in the sultry environment, it seemed to dehydrate and dry Chu Hao!

Caught off guard this time, Chu Hao was almost choked by this heat wave.

coughed a few times in a row, and Chu Hao's joy was even heavier!

Because he knew that he should have touched the root of the secret realm!

Otherwise, this secret realm like a dead place would not have such a strong backlash! And Chu Hao didn't plan to use the Ice Heart Mantra this time, and he didn't use the spiritual power barrier to isolate it!

Communicating with fire and fire attributes is the safest way, and if you use the technique of mutual restraint, I'm afraid it will outweigh the losses!

Chu Hao thought of it, and there was a thunder fire Tiangang among the supernatural powers he cultivated, and he immediately used it, only to see the flames, thunder and lightning stirring, making a crackling sound in the entire silent space, which was very harsh and dazzling.

Chu Hao's divine consciousness was wrapped by the thunder fire Tiangang, and directly entered the center point where the heat wave came, and this time he was not disappointed, only to see that in that place, there was a flame less than the size of a thumb burning!

The flame was pure white, and if you didn't pay attention, you wouldn't be able to spot it!

It's been eight days, and I've finally found out!

Chu Hao was overjoyed in his heart, and the moment he discovered this fire, a voice suddenly sounded in the secret realm.

And the source of this sound is actually the fire below!

"Flame Spirit!"

Chu Hao didn't know what he thought, and couldn't help but shout, and his voice was full of surprise!

※※※※※※※※※※※※※

And during the eight days that Chu Hao was studying the different parts of the secret realm in the Hongtian Secret Realm, somewhere in the Heavenly Demon Mountain Range, there were more than a dozen people standing impatiently on the top of a mountain peak waiting at this moment.

This place is close to the outer edge of the Heavenly Demon Mountain Range, and it seems that these people are planning to leave the Heavenly Demon Mountain Range.

In this line, there are men and women, those who are high in cultivation have the middle stage of yin and yang, and those who are low in cultivation still have the yuan infant stage.

"Yang Le's boys, why haven't they come back yet?"

At the head was a man in the middle of the yin and yang period, with a fierce look on his face, and at this moment there were thirteen people standing around him, except for a monk from the early stage of yin and yang who could stand side by side with him, the other twelve people were all standing respectfully behind him.

If Chu Hao was here, he would definitely be surprised to find that although the costumes of this group of people were a little different in detail, they were generally similar to the few Haoyang Palace disciples he killed!
