One set of equipment for one person is not a difficult task for Xiao Yu, as long as the first set is successful, the rest can become very easy. Of course, Xiao Yu didn't refine it on a large scale, he only built more than ten sets, including Qin Yang and his two subordinates, one was a martial saint, and the other was a king, and their strength was very strong.

Xiao Yu's side is mainly himself and the mechanical female sword saint, such a power is strong enough, and the flame armor is for the two twin kings to use, as for the rest of Qin Yang wants to buy them together, these things may need to wait until the matter is over.

The group began to enter the Fire Cloud Cave, and with the Flame Armor, the terrible temperature no longer bothered everyone for the time being.

"Hah! This Flame Armor is a really good thing, and it is a perfect match for my Flame Beast. ”

Qin Yang appeared on a flame beast, he liked this combination very much, even if he encountered a first-grade martial saint in the future, he might be able to fight. Qin Yang was very excited, and he was about to open the way in front of him on the Flame Beast, but his two guards didn't dare to let him explore the way, so they desperately pulled him back.

Xiao Yu looked a little funny, he felt that this third brother was sometimes like a child, easy to play tricks. Naturally, it is most appropriate to hand over such a thing as pathfinding to the mechanical female swordmaster,

The biggest threat to the Fire Cloud Cave was the terrifying high temperature, and when Xiao Yu and his party had the Flame Armor, the Fire Cloud Cave became safe.

The formation of the Fire Cloud Cave is very strange, there is no fire here, and there is no environment that can form a terrifying high temperature underground, so the biggest possibility in this situation is that there is some treasure. Qin Yang was very enthusiastic about treasure exploration, he definitely had this intention when he came here, but it was a pity that he couldn't enter the Huoyun Cave at all, so no matter what was inside, it was in vain.

The Fire Cloud Cave is extending underground, and the temperature is getting more and more terrifying, but the progress is still much in line with Xiao Yu's expectations. When they traveled hundreds of meters, the passage that extended underground disappeared, and an underground world appeared in front of everyone.

The underground world is very large, the temperature here is very terrifying, far higher than in the cave, Xiao Yu and his party can obviously feel very human when they walk into this underground world.

However, no one cared about the temperature here, but looked at the underground world in front of them in surprise, with all kinds of crimson ores lined up, forming a gorgeous underground world.

"It's an amazing place."

Qin Yang was dumbfounded, who would have thought that there would be such a scene here.

Before Xiao Yu could speak, a voice suddenly sounded in his head: "I found the breath of an artifact here, the luck of the adults seems to be very good, and the environment here should be caused by this artifact." ”

"Artifact?"

Xiao Yu was stunned for a moment, as a creator, he naturally knew the artifact, this was a weapon that surpassed the immortal weapon, the power was very terrifying, and it could definitely destroy the heavens and the earth.

"This artifact is not the artifact imagined by adults, this is a real artifact, with its own spirit and divine method, but I feel that this artifact should be broken, but I don't know how much power is left."

"A spirit artifact?"

Xiao Yu was stunned: "What kind of artifact is that?" ”

"This is an artifact in the true sense of the word, if you want to divide it from the level of martial arts, it must have surpassed the martial god, and only a master of the venerable level can create this kind of artifact."

Mi'er's words surprised Xiao Yu very much, he naturally knew what kind of existence the Venerable Master was, thinking about the Destiny Wheel Tianzun, he knew that such a genius definitely had the power to destroy the heavens and the earth. If the artifact here was really created by a powerhouse of the level of the Destiny Wheel Heavenly Venerable, even if the artifact had been damaged and mutilated, he thought it would be a very amazing thing.

"Do you know where this artifact is?"

"It should be deep underground, and I feel like I should have to go down a thousand meters, at least through the flame stone that the adults first encountered."

Mi'er's words made Xiao Yu's interest rise all of a sudden, but he didn't rush into the depths, but planned to mine the ore here. Xiao Yu knew very well that only he could mine the ores in this kind of place, and he would definitely not come here in the future, so he still took this opportunity to get these ores away.

Mining is really very easy for a creator, especially this kind of ore with a very high gold content, Xiao Yu can directly use the creation technique.

The mining of the ore was done by Xiao Yu alone, and the rest of the people were watching the play on the sidelines, their expressions were all dumbfounded, the profession of creator was definitely not something that could be seen in the Dark Ancient Domain, and now their expressions were very exaggerated when they witnessed such an incredible scene.

"Damn, what kind of Divine Weapon Pavilion can die, my sixth brother's ability is enough to knock them to the ground and ravage them constantly, this is not a grade of technology at all."

Qin Yang was very shocked, Xiao Yu subverted his cognition again and again, making him feel very embarrassed with a mountain man who had never seen the world.

Harvesting the ore did not waste too much time on Xiao Yu, the creator's methods were absolutely amazing, and the ore could be divided and separated independently through gold power, except for some particularly stubborn objects, it was basically very easy to get it.

After collecting all the good-quality ores into the Xuanjie, Xiao Yu's face finally showed a satisfied smile, this time the harvest in Jeju was not ordinary. Although he didn't see the silver and gold that Xiao Yu needed, it was a major gain to be able to obtain so many fire attribute ores.

Continuing to go deeper, it was still very smooth to open the way with the mechanical female sword master, but Xiao Yu and his party smashed close to the original area of flame stones that had been mined a lot and found that the temperature was definitely doubled if they went deeper, even the flame armor he created couldn't bear it

What to do?

Xiao Yu decided to reshape the flame armor, of course, this reshaping is not to reshape the outer armor, he plans to create an inner armor specially designed to isolate the high temperature, with this thing, even if the outer armor dissolves, it will not hurt the user. However, Xiao Yu didn't intend to let everyone go into the deepest depths, he felt that it must be very dangerous to go deeper, and there was no need for everyone to follow.

Qin Yang wanted to enter the deepest part very much, but he was still persuaded by the Martial Saint and the Feng King around him, which made him very regretful.

"Your Highness must pay attention to safety."

It didn't take long for Xiao Yu to build the inner armor, this is made of immortal gold, as for the weaving method, it is very special, this is the weaving technique specially used to resist flames in the creation technique, this thing is very complicated, and he only created a set of inner armor in front of him, which is why he didn't want to bring everyone in.

Although there was only one set of inner armor, of course, there were eight mechanical female swordmasters who entered the depths, and the heat here did not dissolve their bodies. Of course, Xiao Yu didn't let these female sword saints run naked, he still put on outer armor for them, so that he could better protect them.

Although the mechanical female swordmaster is just a robot made of immortal gold, Xiao Yu will still subconsciously treat them as real people, and give them armor as a matter of course.

……

Xiao Yu finally passed through the flame stone area under the escort of the eight mechanical female sword saints, the temperature here was really much higher, if he didn't put on the inner armor, I am afraid that it would not be long before the outside world would become hot, and he would definitely be burned in it.

Xiao Yu struggled to move forward, the terrible heat around him made him feel very uncomfortable, and it felt as if a simple breath could suck the flames into his lungs. At that moment, my organs were about to be burned, and I felt really uncomfortable.

Suddenly!

Xiao Yu felt that he heard the roar of the beast, which surprised him very much, but after encountering the flame beast, it was not an incredible thing to encounter other fire-attribute beasts here.

It's just that as Xiao Yu approached the direction where the voice came from, his face couldn't help but change.

The breath was very terrifying, Xiao Yu found that the breath from the strange beast was by no means at the level of a king, and he felt that there were at least six grades or more.

More than six grades?

Xiao Yu was very surprised, he was now very sensitive to a powerhouse of the level of Martial Saint, so when he sensed a strange beast, he judged that it was at least a sixth-grade or higher.

Xiao Yu knew very well that although there were three sixth-grade sword saints around him, the power of the alien beasts was completely very powerful, and it was not comparable to a martial artist.

Soon an underground lake appeared in front of Xiao Yu, full of terrifying magma, and the terrible temperature frightened him.

Xiao Yu's gaze passed through the underground lake, and Xiao Yu saw two huge beasts facing each other. It should have been a lizard in appearance, and its dark scales emitted a terrible chill against the flames.

Eight pins!

Xiao Yu gasped, the strength of the two lizards was much stronger than he imagined, and the strength of the eighth-grade martial saint level made their strength like that storm.

"Roar!"

A low roar came from the mouth of a lizard, and in a flash of lightning, the lizard disappeared from its place, and at that moment it was obvious that the rocks under his feet were shaking, and it was as clear as if a mountain had slammed into the ground.

"Bump!"

When the lizard reappeared, it had already collided with another lizard, and the terrible impact made a terrible sound, and the surrounding rocks were directly shattered by the sound

The dull collision made Xiao Yu feel like his scalp was about to burst, the flesh of these two lizards was too powerful, and he felt that if he was hit, he was afraid that he would be hit and broken even if he was wearing a two-piece suit.

At the level of the Eight-Rank Martial Saint, Xiao Yu knew very well that he was by no means the opponent of the two lizards, even if he sent out all the mechanical female sword saints, he was afraid that he would be defeated by these two lizards in the most brutal way. Of course, if you just travel through this area, it's not impossible, maybe the mechanical female swordmaster doesn't have the strength of these lizards, but their speed is definitely very powerful.

Use your speed to turn up the lizard and traverse the area.

This is Xiao Yu's strategy, which is very simple, but to implement it, it still needs the mechanical female sword master to play perfectly. According to Xiao Yu's judgment, the strength of the two lizards was terrifying, but they were not speed-type alien beasts.
