The third floor of Chidi Pagoda.

The four Lu Chen and the others are studying how to crack the ban on the fourth floor. The seal on the fourth floor is obviously much more complicated than the third floor. Even Lu Chen and Nie Tianli can only see that it is an extremely clever fire formation. , I can't tell the name and origin of the formation.

Nie Tianli tried to forcibly break the formation and wanted to destroy the seal, but was counterattacked by the force of the ban, and he was injured a little bit. If he hadn't reacted quickly, he would have been seriously injured on the spot.

Miao Jiu was unable to break the seal on the fourth layer even using the Flame God Cauldron.

This was mainly because Miao Jiu had never been to the third floor before, and had not done any research on this seal, and he could not see the principle of the formation, so naturally he could not crack it.

"If you want to crack the rune formation, you must first understand how the formation works. This requires patience." Lu Chen reassured everyone. In this dull and restless atmosphere, it was difficult for even Nie Tianli to maintain his temperament, but If the mood is too impetuous, it will not help to solve the problem.

Nie Tianli was very impressed when he saw that Lu Chen was still able to remain calm and calm. Under the infection of Lu Chen, he also became calm and began to study the rune formation with peace of mind.

Liao Tongming was very surprised when he saw this situation. In his opinion, Lu Chen was just a talented young man, but in many ways, Lu Chen has a potential influence on others, even he Have to admit.

If someone can keep their minds, it will be an encouragement to teammates in any environment. Seeing that Lu Chen and Nie Tianli can study the formation method calmly, Liao Tongming and Miao Jiu are both looking forward to it.

The two of them had too little attainment in the formation, so they could only pin their hopes on Lu Chen and Nie Tianli.

Time passed minute by minute, and soon a day and a night passed.

In order to study this rune formation, Lu Chen and Nie Tianli didn't stop to rest for a while. By now, both of them were sweating profusely and felt a sense of mental weakness and exhaustion. The masters fought all day and night, exhausting their energy.

Studying the rune formation does not need to consume power, but it consumes mental power in particular, and it is easy to cause trauma to people's spiritual consciousness.

The two had to stop to rest, meditate, and slowly recover.

After studying for a day and a night, the two of them have already seen a little bit of the formation, which can be regarded as a bit of achievement.

For this ancient formation, Lu Chen also has to admire it. This formation is indeed extremely complicated. Even a master of this formation is very difficult to study. This is only the fourth layer. What should the fifth layer be like? , it is unimaginable.

Four days later, Lu Chen and Nie Tianli finally thoroughly studied the general situation of the formation and mastered the operation rules of the formation. In order to understand this formation, after four days, Lu Chen and Nie Tianli were almost exhausted.

"I finally figured it out. This formation needs to be motivated by a strong fire attribute profound energy. Lu Chen, are you sure?" Although Nie Tianli understood the formation, it was precisely because he understood the power of the formation that he Only then did he know that this formation requires extremely strong fire spirit power. With Lu Chen's current cultivation, it is almost impossible to motivate him, so he is still in a bad mood.

Lu Chen said: "Don't be too pessimistic, there is still a way. I remember that the Yanshen Ding seems to be able to gather fire spirit power in a large amount and use it to decipher this formation. It should work."

If Lu Chen reaches the Primordial Spirit Realm, with his accomplishments in Lihuoshengong, he can crack this rune formation without the Flame God Cauldron. But now, it is necessary to use external force.

Miao Jiu took out the Flame God Cauldron, gave it to Lu Chen, and told Lu Chen how to use it.

Miao Jiu didn't know much about how to use the Yanshen Cauldron, mainly limited to his cultivation and knowledge, but Lu Chen was much better than him in terms of strength and knowledge. The method Miao Jiu said, Lu Chen could take it easy. By drawing inferences from one case to another, he quickly mastered the use of the Flame God Cauldron very well.

Lu Chen placed the Flame God Cauldron at the entrance of the fourth floor, and then slapped the flame God Cauldron with his palm. The strong fire attribute profound energy poured into the Flame God Cauldron, and then, the free fire spirit power in the air on the third floor was directed towards the flame God Cauldron. The Flame God Cauldron gathered, and the entire Flame God Cauldron emitted a faint red light, showing a very strong and rich fire spirit power. Momentum about to explode.

Lu Chen suddenly mobilized the pulseless divine art with all his strength, and entrusted all the fire spirit power, all the fire element profound energy and spiritual power of the Yanshen Ding into the rune formation. , an aura that burns the heavens and all things spreads out.

Feeling this terrifying aura, even Nie Tianli and Liao Tongming were taken aback, almost instinctively, they both retreated involuntarily.

This fire spirit is too powerful.

"How can there be such a powerful flame in the world?" Both Nie Tianli and Liao Tongming had this question. This kind of flame is much stronger than the power of the spirit fire of the fourth-order monster beast, the fire spirit bird.

"Not good." Lu Chen said suddenly, this sudden flame was the pure source fire, and even Lu Chen didn't dare to touch the slightest bit, and hurriedly jumped aside to avoid the burning of the flame .

But as a result, there was no way to continue to control the Flame God Cauldron, and the rune formation on the door was extinguished in an instant, returning to peace.

Array cracking failed.

"This flame is too powerful to be cracked in this way," Lu Chen said.

Nie Tianli frowned and said, "Could this flame just now be the legendary fire of origin?" He had never seen the fire of origin, but he could sense it intuitively.

Lu Chen nodded and said, "It's the fire of the source, and it's a very pure fire of the source. Even I can't get close."

Lu Chen's Lihuo Divine Art has been completed, and logically speaking, he should be a master of playing with fire, but in front of this pure fire of origin, even his Lihuo Divine Art is not enough.

The Fire Spirit Bird Inner Pill also contains the source fire, but the source fire energy is very thin, so Lu Chen can use it for research, but like this pure source fire, there is no way to get close, barely resisting, it is very easy Play with fire and set yourself on fire.

"What should I do then?" Liao Tongming said anxiously.

"It can still be cracked, but it's a little troublesome. The fire spirit power gathered just now is indeed enough, but the fire spirit power is too thick and violent, and it is difficult to control, so it will make such a big movement when cracking the seal." Lu Chen After speaking, he took out the Fire Spirit Bird Inner Pill from the cave ring, and continued, "This is the Fire Spirit Bird Inner Pill, which contains some source power. As long as the fire spirit power in the inner pill is poured into the Yanshen Cauldron, you can Break the seal."

The fire spirit power in the Fire Spirit Bird's inner pill is much worse than the pure source fire, but it is much stronger than the fire spirit power element free in the air, and it is easy to control, as long as the fire spirit bird is fully activated Dan, coupled with Lu Chen's fire-free magic, can theoretically break the seal.

Lu Chen directly asked the Fire Spirit Bird Inner Pill to be placed in the Flame God Cauldron and began to slowly activate the Flame God Cauldron. This time, he spent ten times more time than the previous time, because the Fire Spirit Bird Inner Pill was not allowed to be refined. , not to mention that Lu Chen must be stable, and this time he cannot fail again.

After more than half an hour, the Flame God Cauldron emitted a fierce red light again. This time, the fire spirit power didn't seem as strong as the last time, but the power in it was much stronger than the last time. Obviously, the purity was already very high.

Everyone watched Lu Chen crack the formation with anticipation.

After another moment, Lu Chen carefully activated the pulseless magic, poured all the Lihuo profound energy into the Flame God Cauldron, and then guided the Flame God Cauldron to integrate the Fire Spirit Power into the Rune Formation.

This time the whole process seemed very long, but it was stable enough. With the slow injection of fire spirit power, the rune formation did not have the last flame eruption. It was very smooth, and the door of prohibition slowly opened.

"Finally, I didn't live up to everyone's expectations." Lu Chen's face was a little tired, but he was still very relieved.

Everyone was overjoyed, and Nie Tian laughed and said, "Your credit is the greatest. If there is any good stuff in it, it's up to you to choose first."

Everyone entered the fourth floor.

As soon as he walked into the fourth floor, Lu Chen sensed the unusualness in it. The fire spirit in the air had an aura of the fire of the origin. The aura of the fire of the origin was very gentle, and it was completely possible to practice in it. , This will definitely be of great help to the breakthrough of Lihuo Shengong again.

However, Lu Chen was not in a hurry to practice Li Huo Shen Gong, because he sensed a powerful fire spirit coming from a certain direction, Lu Chen followed this breath, and soon found that the person in front of him was In one corner, there is a black stone platform.

There are several shiny jade bones on the stone platform, like the leg bones of monsters, and there is an oil lamp on the right that has been extinguished. On the side of the stone platform, there are many ancient pictures engraved. These pictures show many people facing one. The scene of worship on the stone platform.

"This is an altar," Nie Tianli said suddenly.

"It's really like an altar." Lu Chen nodded in agreement.

The shape of the altar is a bit strange, and the shape is a bit like a flame god.

However, apart from this altar, what disappointed everyone was that there was nothing on the fourth floor.

Compared to the tens of billions of spar refining materials on the third floor, this place is really too clean and rudimentary, except for an altar, there is not even a little extra decoration.

"Grandma is a bear. After all this hard work, there is actually nothing on it. Isn't this a trick?" Nie Tian complained fiercely.

Lu Chen said: "It's disappointing, but this should only be a top-level practice place. For those who practice fire attributes, practicing here is no less than in the ancient realm."

Nie Tianli said, "That's only useful to you. I don't practice fire-type exercises."

At this time, Liao Tongming suddenly shouted: "There are many futons here."

Lu Chen and Nie Tianli both walked to Liao Tongming's location, and soon they discovered that there was indeed a row of futons for meditation on the ground, and it seemed that these futons were a bit special, at least in this position, the fire spirit power was compared to other places. To be thicker.

"It seems that this place is really a place to practice." Nie Tianli said.

Although there were more than a dozen futons on the ground, only Lu Chen and Miao Jiu could use them, so Nie Tianli and Liao Tongming were naturally disappointed.

After turning around a few times, everyone still didn't find anything special on the fourth floor. Lu Chen and Miao Jiu simply sat on the futon, held Yuan and guarded one, and began to refine the fire spirit power.
