But if you want to cultivate the Five Elements Spiritual Fire, the process is also extremely difficult, and just cultivating the Five Elements Exercises alone will stump nine out of nine immortal cultivators.

Even if an immortal cultivator cultivates an attribute exercise, it will take decades or even hundreds of years of hard work, not to mention the five kinds of exercises and practitioners, even if the Jindan monk has a lifespan of five or six hundred years, very few people will choose to cultivate this five elements spiritual fire.

This makes the Five Elements Spiritual Fire famous in the world of cultivating immortals, and its power is also quite impressive, but there are very few who have really cultivated and achieved something.

However, the Five Elements Spiritual Fire in front of him is obviously still in its infancy, and the true Five Elements Spiritual Fire in the legend exudes not a colorful color, but a white and gold color.

If it really reaches this level, it indicates that the five elements spiritual fire has been completely fused, endless, once it is unleashed, it is enough to bareland for a hundred miles, even if the immortal cultivators in the early stage of the Yuan Infant encounter this kind of spiritual fire, they must retreat.

Although Han Changlin was surprised that there was actually the existence of the Five Elements Spiritual Fire in this [Sutra] Character Gate, what surprised him even more was that the ancient book was able to withstand the scorching of the Five Elements Spiritual Fire.

Moreover, this Heavenly Flame Valley has appeared for thousands of years, and the Secret Palace has never been born in these thousands of years, which means that this ancient book has been scorched by the five elements of spiritual fire for thousands of years.

But in Han Changlin's opinion, this ancient book did not show any signs of damage except for some yellowing on the surface, which really surprised Han Changlin.

Han Changlin secretly spread his mana all over his body, and the burning feeling gradually became less obvious, and when he came to the stone pier, Han Changlin observed it carefully.

This ancient book looked very ordinary, no different from what Han Changlin had seen in the Imperial Spirit Sect Library Pavilion, but Han Changlin knew one thing very well, those ancient books in the Library Pavilion, let alone being burned by the Five Elements Spiritual Fire, even if it was an ordinary flame, it was enough to burn them to the ground.

"Could this ancient book be the one that Feng Yixiao and his wife said?"

Han Changlin already had seven or eight points of belief in his heart that this ancient book was the one that Feng Yixiao and his wife never forgot, after all, after entering the secret palace, Zhou Li also looked at this [scripture] character door, and looked extremely excited.

It's just that Han Changlin didn't know what secrets were hidden in this ancient book, which made Feng Yixiao and his wife so persistent, and even made a promise that as long as this ancient book, the rest of the treasures would be abandoned.

After pondering for a while, Han Changlin stretched out his left hand, emitted a mana aura from his palm, turned into a big hand several feet long, and grabbed it towards the ancient book.

"Zizizi."

When Han Changlin's spiritual light was grabbed into the Five Elements Spiritual Fire, there was a piercing sound, and at the same time, Han Changlin felt that the mana in his body was actually being consumed at an alarming speed, and in the blink of an eye, half of his kung fu was consumed.

Han Changlin's face changed slightly, in addition to his spiritual light big hand, he also blessed the Extreme Yang True Fire, just to use the Extreme Yang True Fire to resist the burning power of the Five Elements Spiritual Fire.

The Extreme Yang True Fire did not disappoint Han Changlin, resisting the scorching of the Five Elements Spiritual Fire, but it was obviously quite difficult, and the sharp consumption of mana was a good proof of this.

The only thing that made Han Changlin happy was that except for the rapid consumption of mana, there were no other changes, and Han Changlin copied the ancient book into his hand very easily.

And after the ancient book was taken away by Han Changlin, the five elements spiritual fire on the stone pier suddenly retracted and disappeared without a trace.

Seeing this scene, Han Changlin showed a surprised expression on his face, and after thinking slightly, he gently came to the stone pier and looked towards the hole in the stone pier.

"Huh?"

Han Changlin exclaimed, it turned out that in the center of the hole in the stone pier, there was a stone egg with a mottled surface, at first glance, it looked like an iron ball with a rusty surface.

But the faint breath of life emanating from it made Han Changlin understand that this should be a demon beast egg, not a real iron ball.

Han Changlin didn't dare to reach out directly to get it, so he turned into a spiritual hand again, went deep into the hole, and scooped up the stone egg.

After doing all this, Han Changlin put the stone egg on the ground, and carefully observed that the surface of the stone egg was uneven, one white and one yellow, and some places showed dark orange.

No matter how you look at it, it doesn't look like a real demon beast egg, Han Changlin looked at it for a long time, and he couldn't see a reason, besides, now is not the time to study, Han Changlin casually threw the stone egg into the spirit beast bag.

As for the ancient book, Han Changlin also put it directly into the storage bag, and he would study it carefully when he had time in the future.

Immediately afterwards, Han Changlin looked around, in this stone room, in addition to the central stone pier, there was also a bookshelf on the side, on which some porcelain bowls and vases were placed.

Han Changlin casually picked up a vase and examined it carefully, and after half an hour, Han Changlin put down the porcelain bowl in his hand and breathed a sigh of relief.

These porcelain bowls and vases are all very ordinary items, and they are of no use to immortal cultivators except for being older.

Han Changlin spent another half an hour searching the entire stone room, not only did he not have any other items, but even the exit was not found, and Han Changlin did not continue to stay in the stone room.

Instead, he turned around and left the stone room, and outside the stone gate, the second-order Spirit Devouring Insect had once again gnawed out a gap of a few feet in the forbidden spiritual light, and Han Changlin flickered lightly, and came to the main hall on the first floor of the Secret Palace.

The roar outside became more and more intense, and Han Changlin could even see that above his head, there was already a faint layer of forbidden aura left, obviously it wouldn't be long before the Wind Illusion Thousand Nights Spiritual Forbidden outside would be broken.

Next, Han Changlin controlled those second-order spirit devouring insects to enter the spirit beast bag one after another, and then Han Changlin jumped directly towards the waterhole under the second layer of the secret palace.

Entering the water, Han Changlin felt a cold aura coming from his surroundings, but for him, it was no big deal, Han Changlin urged the mana in his body, forming an air flow under his feet, pushing him towards the depths.

After dropping a hundred zhang deep, Han Changlin's feet stepped on a stone, Han Changlin felt as if a boulder had been pressed on his body, even with his cultivation in the later stage of foundation building, he also felt inconvenient to move.

Looking around, suddenly, there were a series of colorless spiritual lights in the distance, reflecting the dim bottom of the water alternately light and dark.

Han Changlin's heart moved, and then swam in the direction of those spiritual lights.

After the tea effort, Han Changlin saw that not far ahead, there was a palace with a pitch-black body, and this palace looked like it was forged from a whole piece of dark cloud crystal, which could be described as a big deal.

Although the dark cloud crystal is only the best material for refining magic weapons, such a large piece is enough to make people marvel inexplicably.

I'm afraid that only the Giant Dragon Sect back then had such huge financial resources.

Han Changlin couldn't help but speed up and came to the palace gate, the palace did not have a portal, but at the position of the palace gate, a layer of light black light curtain flickered.

Han Changlin stepped out, went straight through the light curtain, and came to the palace, in this palace, there was not a drop of water, obviously the light curtain behind him was the prohibition of isolating the pool of water outside.

At this moment, Han Changlin saw that the hall was in a mess, the stone pillars were even more crooked, and the original few ever-bright lamps were also knocked to the ground.

However, Han Changlin didn't see Ruan Biqin, Hua Feiyang and others, which made him a little puzzled.

"Could it be that someone has already entered here? Or did Ruan Biqin and Hua Feiyang see some kind of treasure and fight for it? ”

This made Han Changlin more and more cautious.

With a gentle tap of the storage bag on his waist, the Blue Flame Sword suddenly turned into a sharp aura and flew out, falling into Han Changlin's hand, swallowing a sword light that was a few feet long.

The Nine Star Blade of the Mother and Son, plus the Blue Flame Sword, as well as the shield-shaped mid-level spiritual weapon "Void Yuan Shield" that had been surrounding Han Changlin's side, as well as the mana shield that was hidden around the body and was contaminated with the Extreme Yang True Fire.

In Han Changlin's opinion, it is enough to deal with some unpredictable dangers.

After doing all this, Han Changlin cautiously walked towards the palace.

As Han Changlin went deeper and deeper, the expression of surprise on his face became more and more intense, from the outside, although this palace was majestic, it was only a hundred zhang in size.

But the distance he has walked now is probably more than a thousand zhang, and the road he is traveling is also showing a slight downward trend, which makes Han Changlin understand that the road in front of him may have gone deep into the bottom of the water.

Obviously, the palace made of dark cloud crystals was just a portal.

This made Han Changlin admire the Giant Dragon Sect more and more, and he actually built such a secret palace that is beyond the understanding of ordinary people, so it can be seen that it was not a fluke that the Giant Dragon Sect surpassed the entire Immortal Cultivation Realm back then, and its own strength was enough to make it do this.

Han Changlin was also full of curiosity about the truth about the collapse of the Giant Dragon Sect back then, what kind of existence could destroy a large sect overnight, and there were ten Yuanying monks and more than a hundred Jindan monks in this sect.

This kind of strength, even if it is a great monk or even a god cultivator, may not be able to do it, right?

At the same time, Han Changlin thought of Feng Yixiao and his wife, these two people are now quite mysterious in Han Changlin's opinion, and the origin of the two is probably related to the Dragon Sect, otherwise the secret palace is such a secret place, but the two of them know it quite carefully.

Moreover, in order to enter the secret palace, the two of them were deliberate, and in order to enter this secret palace, they took great pains to select themselves and Ruan Biqin and other seven immortal cultivators whose mana far exceeded that of ordinary monks of the same level, and came to explore the secret together.

Han Changlin believed that Feng Yixiao and his wife must know far more about the secrets of the Secret Palace than they revealed to the seven of them.

This is also the fundamental reason why Han Changlin chose to enter through the Spirit Devouring Insect after he was so excited when he found out that Zhou Li saw the [Sutra] word door.

Although Han Changlin didn't know what the purpose of that ancient book was, it must not be an ordinary thing to make Feng Yixiao and his wife so eager to get it.

The only thing that made Han Changlin a little regretful was that he didn't have more time to enter the other three secret rooms.
