Nanming Lihuo and Chiyang Zhenhuo each have their own advantages, but they also have shortcomings.

No matter which one you use, it can't be perfect.

Because it was the first to obtain the True Fire of the Red Sun, and it has been turned into the heart of the soul, it is not easy to replace it now.

Therefore, after Wang Daoyuan obtained the stronger Nanming Lihuo, he did not use it to replace the Red Sun True Fire.

Xuanyuan pondered for a moment: "I have also seen some of the origin of the Red Yang True Fire.

Some are similar to Sun Fire, but obviously impure. It should come from some kind of demon bird with Golden Crow bloodline.

However, in recent years, the Red Sun True Fire seems to be gradually moving closer to the True Sun Fire.”

Wang Daoyuan nodded: "This is indeed true. I understood the laws of the sun and lunar yin with the help of the source of the sun and the moon. This is a law I mastered before I broke through to the Mahayana.

Nourished by the law of the sun, the pure Yang attribute of the Red Yang True Fire will naturally continue to increase.

In fact, now, I no longer rely on the power of the spiritual fire itself for offense and defense.

Especially the Red Sun True Fire, which itself comes from a low-level demon bird and has limited potential.

If I hadn't mastered the law of the sun and made it move closer to the true fire of the sun, I'm afraid it would have been useless.

Three of the other four spiritual fires are naturally occurring and have unlimited potential.

The Life Spirit Fire is produced by the Xuantian Bi Ling Peach. It can be regarded as coming from the fairy world, and its potential is naturally not small.

The weakest spiritual fire is the Red Sun True Fire.

If you can fuse it, even if you use real sun fire to fuse it, it would be a good choice."

"So, master, you have a much greater advantage than Jin He.

You already have the same solar law as Jinhe, and the destruction law corresponding to the red sun true fire.

The vision of Zifu is Yinglong, and it also carries the law of Suzaku.

With Nanming Lihuo in your hand, you can fully understand this law.

With the guidance of rules, the probability of success will be much higher."

Wang Daoyuan smiled and said: "So, I am indeed more suitable for performing the Melting Fire Technique than the demon fairy Jin He.

However, let’s develop all the treasures in this secret realm first.

I don't have any safe place to go south of Juetian Abyss, so I might as well practice in this secret realm first.

Xuanyuan, after we solve the last palace, you go to the secret realm and set up a large formation to isolate and detect, and I will try to fuse the flames here."

"Don't worry, Master, I have already prepared many formation bases in the spirit bead space and can be used at any time.

When we broke the formation before, it didn't cause much commotion.

Unless a person or monster with extremely high cultivation level flies nearby and investigates carefully, there is no way to discover that there is a secret entrance to the seabed."

Wang Daoyuan nodded, put all the books into the spirit bead space, and walked out of the second hall.

One person and one turtle came to the third hall, and the entire hall was shrouded in a defensive light shield.

Moreover, this defensive formation is relatively complete, so it is somewhat difficult to break through.

"Xuan Yuan, I leave this formation to you.

The only direct descendant of the true immortal, the young master of the formation family, it shouldn’t be a problem to break this formation."

Xuanyuan was also full of confidence: "Master, don't worry, no matter how strong this formation is, it has been left unattended for more than 300,000 years, and there will definitely be flaws.

I'm not sure about solving the formation, but it's still possible to find the weakness of the formation.

The spiritual veins here are only seventh-level high-grade formations. No matter how brilliant his formation is, it will not exceed the seventh-level high-grade formation by much.

With your strength, Master, it will not be a problem to break through the weaknesses of the formation."

After saying that, several black rays of light condensed in his hand.

These rays of light flew out and went straight into the defensive light shield.

As soon as it touches the defensive light shield, the black light disappears.

Xuanyuan stretched out a turtle claw, and the same black light appeared again.

However, these rays of light did not fly out again, but wandered around in his palm.

After more than a hundred breaths, the light in Xuanyuan's palm formed a gray shadow.

This phantom is exactly the same as the third palace, and it is also wrapped with a layer of formation.

In the shadow, even the energy flow within the defensive light shield can be seen clearly.

Wang Daoyuan exclaimed: "Good guy, you can easily simulate the function of a compass to detect an array."

Xuanyuan chuckled lightly: "I also have a compass for exploring the formation, it is passed down from my ancestors.

To break a remaining formation, there is no need for compass to take action.

My method can also detect all the characteristics of the formation.

The True Immortal Ancestor also created a method to break the formation. These black rays of light are integrated into the formation and can directly destroy the formation restrictions.

Unfortunately, I am only at the seventh level mid-level now.

To practice that formation-breaking secret technique, one must have at least the cultivation level of a third-level Earth Immortal.

Otherwise, a mere small formation means nothing."

Wang Daoyuan was a little shocked that the secret skills of the immortal world were so powerful.

Even if Xuanyuan is bragging, but excluding the bragging part, he may actually have a way to break through the formation.

After half a cup of tea, the shadow in Xuanyuan's hand stabilized.

I saw his other tortoise claw pointing out one after another on the shadow of the main hall, and soon, several thick black dots appeared on the shadow of the defensive formation.

"This is the flaw in the formation. No one has taken care of it for hundreds of thousands of years. There are many problems with the formation."

After saying that, he waved his turtle claws and the shadow completely dissipated.

At the same time, several black light spots appeared on the defensive light shield of the main hall in front.

"Master, all you need to do is deal with these black light spots."

Wang Daoyuan nodded, pointed his sword with his right hand, and pointed a bright yellow sword energy directly at a black spot.

Click~~

The defensive mask was already overwhelmed, and this sword energy hit the weak point again, and the entire mask quickly collapsed.

One person and one turtle came to the door of the main hall. This main hall was not like the previous two.

The golden light flowing on the palace door clearly indicates some kind of trick.

Xuanyuan carefully leaned over and observed it carefully.

"Master, the method on this door is not a formation, but more like a trap.

There are means left inside in advance, and as soon as the door is touched, the means will burst out.

We are not sure how powerful the means on this gate are now, and this gate cannot be touched easily."

Wang Daoyuan nodded, walked to the wall next to the door, and knocked on the wall with his hand.

"The material of this wall is unusual. Xuanyuan, come and see if it is any precious material."

Xuanyuan walked over and scratched the wall.

Like the first two palaces, the wall surface is covered with a layer of paint.

The wall is a translucent material, like a kind of colored glaze.

"It's really a special material."

"What special material? Is the Golden Flame Divine Iron valuable?"

Xuanyuan shook his head: "This material is called Golden Flame Glazed, and it has some connection with the Golden Flame Divine Iron.

This thing is the true fire of the sun burning some stones, completely burning the stones into lava, but not completely burning them into nothingness.

After the rock is cooled again, this golden flame glaze will be produced.

Like the Golden Flame Divine Iron, this thing also contains the power of the true fire of the sun.

Moreover, the characteristics of this thing are not suitable for refining magic weapons. It is just a rare building material.

Its strength is extremely high, and it is difficult for Earth Immortals to break it.

Except for the true fire of the sun, there is no way to melt the golden flame glass.

Therefore, the Golden Flame Glaze has almost no effect on the human race, so naturally it cannot be sold at a high price."

Wang Daoyuan sighed softly: "That's a pity. We can only let Chi Yu come out and melt the golden flame glass."

"Master, let's not destroy this thing easily.

If I guessed correctly, the formation center of the entire secret realm should be in this hall.
