Xu Mu cast a spell, his body was wrapped in mana, and he fled towards the ground at an extremely fast speed, and the whole person was like being in the sea, and the hard rock could not form any obstacles.

"Dark iron, refined copper, star spirit! I didn't expect there to be a lot of good things hidden underground! ”

After dropping down and diving to a hundred meters, Xu Mu spread his divine thoughts, and immediately felt a lot of local spiritual mines.

The island where Suxin Palace is located has a medium-sized spiritual vein and several small spiritual veins, and while these spiritual veins provide spiritual energy for the disciples of Suxin Palace to cultivate, they also form a nourishment on the island itself over the years.

Not to mention the various precious spiritual ores underground, the hard level of the stones that make up itself is already comparable to ordinary steel.

It can be said that the entire island where Suxin Palace is located is full of treasures, which is also one of the connotations of Suxin Palace.

In the future, if you have to do so, you can use it for excavation.

The more Xu Mu dived, the more spirit stones and treasures he found, and even saw the medium-sized spirit vein that was like a giant dragon, and a large number of spirit stones had been bred inside.

In order to avoid affecting the spiritual vein, Xu Mu did not come close to take a closer look.

"It stands to reason that a medium-sized spirit vein should already be able to breed a top-grade spirit stone, that's a good thing!"

Compared with the top-grade spirit stone, the top-grade spirit stone has undergone a qualitative change, not only has the function of an ordinary spirit stone, but can also be used as a medicinal material.

If it weren't for the excavation of ores, it would easily affect the spirituality of the spirit veins, Xu Mu really wanted to dig a few and keep them for later use.

"However, I am reluctant to dig for the development of Suxin Palace, which does not mean that others will not dig either!"

Xu Mu spread his divine thoughts into the distance, and sure enough, he found a lot of defensive and vigilance formations, as expected, this must be a formation specially arranged by Suxin Palace in order to prevent outsiders from secretly digging ores.

In addition, Xu Mu also found that from time to time, the divine thoughts of the foundation building period were swept in, and the disciples who were patrolling were obviously arranged.

In addition, in the surrounding waters of the island, there are also spirit beasts domesticated by Suxin Palace, as long as someone wants to sneak in from below, they will soon be discovered.

In this way, the defense of the inner and outer three layers can basically block most of the monks, and a small number of high-level monks can be developed.

For a top monk like Xu Mu, this didn't have much effect.

But this is also normal, if it is the Yuan Infant Period, there is no need to sneak in at all, even if it is excavated openly, it is estimated that Su Xingong will not dare to say anything, as long as it is not too excessive, it will turn a blind eye.

Of course, there shouldn't be such a bold and arrogant Yuan Ying in the Cangming Sea area, everyone knows the roots, if it was really so chaotic, the order would have collapsed long ago.

This is also the reason why the Star Gate has the strength to crush the other two, but it does not dare to mess around at will, and even has to maintain the two.

For all this, he only briefly observed, did not alarm the patrolmen, and did not destroy the formation.

Following the traces of the Earth Fire Formation, after diving for about eight hundred meters, Xu Mu finally felt a scorching aura.

The function of the Earth Fire Formation is to extract the fire spiritual power in the Earth Fire, which is somewhat similar to the effect of the well, not that the Earth Fire is directly exposed on the surface.

If the fire is exposed on the surface, it is a volcano.

At the beginning, the Liyang Sect was located in the Great Array of Earth Fire established on the basis of a volcano, which was not only more powerful, but also more labor-saving in using Earth Fire.

Of course, there are pros and cons.

Because the closer you get to the earth fire, the more violent the fire spirit power becomes, and it also contains the poison of the earth fire, living near the earth fire for a long time will not only make the cultivator's personality irritable and irritable, but also reduce the life span of the cultivator.

This is also the reason why the Lihuo Sect was able to occupy a huge crater with the help of the three primordial infancys.

Of course, if you are willing to spend your money, you can arrange more filtering and control formations. These side effects can also be reduced.

The area involved in this fire vent under Suxin Palace is not small, but because it is far from the ground, it will not have much impact.

The disadvantage is that if you want to mobilize the power of earth and fire in it, you need to spend more spirit stones to run the formation.

At this time, Xu Mu was close to the mouth of the earth's fire, which was different from the ordinary fire spiritual power.

The hot and violent aura hit him, making him feel a little uncomfortable.

However, when he activated his spiritual power, this little feeling was immediately suppressed.

At this time, it was only close, and it was not completely entered.

Xu Mu continued to dive for two or three hundred meters, and then he saw rivers of hot magma, flowing underground.

At this time, the surrounding temperature has reached thousands of degrees, and the rocks that are not hard enough in the vicinity have already melted, forming one cavity after another.

Xu Mu escaped into one of the cavity areas, then took off the magic robe on his body, and gathered the spiritual power in his body.

He came here this time to use these earth fires to cultivate the true body of the Ten Thousand Tribulations, and the robe was engraved with a temperature-controlling formation, which would automatically operate in the face of high temperatures, so that it would not have the effect of exercising.

And because his exercises have already cultivated to an extremely high realm, they will also automatically resist, so they have to be restrained first.

As he put away the robe and the spiritual power of the body protector, the environment that had only felt a little uncomfortable immediately became hot.

However, Xu Mu's Purple Flame Heavenly Thunder Body had already cultivated to an extraordinary level, and his physical body was comparable to an ordinary tenth-order magic weapon, and these temperatures alone were not enough to cause harm to him.

At this time, Xu Mu standing around the earth fire was just like an ordinary person standing under the sun.

Not only did it not feel uncomfortable, but there was a hint of sun-like warmth.

"It seems that the robe is not only ineffective for me, but it has a certain hindrance!" Xu Mu sighed.

Because his physical body is too strong, the magic robe below the tenth order is a complete drag, and the discomfort just now is actually brought about by the operation of the magic weapon formation.

It's like a wild man who is used to living in the mountains and forests, and you suddenly let him put on clothes and feel uncomfortable.

He's at his best now.

However, walking outside is a bit strange if you don't wear clothes.

Because of the temperature near the earth fire, it was not harmful to him at all, so the Ten Thousand Tribulation True Body did not react.

Xu Mu observed the surrounding environment for a while, and after making sure that there was no danger, he stepped naked into the magma.

Woohoo!

The aura around Xu Mu's body immediately burned up the moment it touched the magma, making a sound, but it was quickly burned out.

Faced with this situation, Xu Mu didn't frown and continued to walk deeper until the magma spread to his chest.

At this time, he couldn't help frowning slightly.

"That's too powerful, isn't it?"

Xu Mu, who was immersed in magma, only felt like he had entered a piece of warm water, not only did he not cause any damage, but he was also a little comfortable.

It's been a long time since I've taken a hot shower! (End of chapter)
