Xiao Wenzi knew that this was not the central essence of the fire vein, but if he didn't advance the Demon Yan Ding, I was afraid that even if he used the Infinite Resurrection of the Red Heart to find the true main fire vein, he would not be able to get close at all, let alone devour and refine it.

As a result, he simply started his cultivation and assisted Demon Yanding to swallow the surrounding earth fire and smelt it for his own use.

Although the earth fire in the depths of the earth is terrifying and hot, Xiao Wenzi is not an ordinary demon mosquito.

His body, which surpasses too many demon cultivators of the same level, has been tempered thousands of times, and his strength is not weaker than that of ordinary top-grade magic weapons, and his cultivation is even stronger than that of ordinary False Dan Realm cultivators.

When he really ran his cultivation and refining Demon Yan Ding at full strength, the Demon Yan Ding, whose quality was constantly getting stronger, could completely resist the burning of the surrounding earth fire that was constantly absorbing heat.

Time passed slowly, and the second fire pattern on the wall of the Flame Ding Furnace gradually became clear.

It wasn't until more than half a month later that a red fire pattern with a little sky blue was completely formed, and the first sky blue fire pattern complemented each other.

The second pattern demon Yan Ding, the demon Yan Ding at this moment is really counted as the second pattern of the perfect state.

With it shrouded in the outside of his body, it was difficult for Xiao Wenzi to be harmed by the scorching earth fire around him, and he walked through this karst cave filled with earth fire magma, as easily as walking in his own back garden.

"Hey~, there's a master coming, I'll hide!"

Suddenly, Xiao Wenzi looked up at the rock wall above, exchanged a demon talisman with a thought, and then controlled the demon Yanding to burrow into the depths of the magma and disappear.

The earthy yellow light flickered, and two monks with magic shields appeared above the magma.

They were the elders of the Thousand Illusion Sect who had been waiting for no avail, and were finally sent underground by Fan Tian to search, and one of them was still from the Fan family.

"There is no abnormality, I will say that unless it is a Yuanying powerhouse like Fan Tian's predecessors, who would dare to find death close to the earth fire, let alone escape from it......

Brother Fan, where did you say that the demon who manipulated the demon insects to sneak attack your Fan family's children was hiding? It can't be a mistake, maybe he had the means to leave Millelith City a long time ago. ”

The middle-aged man stared around the cave for a few moments, because his divine sense could not penetrate deep into the magma, and Xiao Wenzi also held a spiritual product demon talisman, he didn't see anything abnormal at all.

After searching underground for a long time, there was no clue, and he, the Jindan Stage Elder of the Thousand Illusion Sect, was a little skeptical of Fan Tian's judgment, thinking that his Fan family was making a big fuss.

"How do I know, since there is no one here, then let's look elsewhere, or give an account to the ancestor. ”

The monk known as Fan Wei shook his head helplessly, and was scorched by the flames of the earth fire at close range, and he was also a little overwhelmed in the middle of Jindan.

It's just that this time, in order to capture the so-called demons, Fan Tian, the ancestor of his Fan family, blocked Qianyan City for more than half a month, and the monks who came here to intersect complained, but Mao didn't find one.

If they can't find the "murderer" hiding underground, then the Fan family will really be thrown home.

"yes, somewhere else. ”

The middle-aged monk of the Thousand Illusion Sect also didn't want to stay in the scorching earth fire, because it required him to spend a lot of cultivation at all times to maintain the magic weapon shield.

As they spoke, the earthy yellow light flickered around the two of them, and they entered the rock wall again and disappeared.

"Fan family, such a big formation, it seems that I have inadvertently offended the overlord-level figures here, but fortunately I hid in the depths of the underground to cultivate in advance, otherwise there would be some trouble. ”

The divine sense of the middle-aged man of the Thousand Illusion Sect and the Jindan monk of the Fan family could not penetrate into the magma to find Xiao Wenzi, but Xiao Wenzi, who was already accustomed to tempering his demon sense with the earth fire magma, could hear their conversation.

I know that the Fan family has dispatched a lot of masters to capture him, but so what? He is now going to find the main fire vein and then devour and refine it.

As long as the level of Demon Yanding can be raised to the state of four lines, unless it is the ancestor of the Fan family who personally makes a move, he is not afraid of the two guys like Fang Cai at all, and no matter how much he comes, it can only be regarded as a food delivery.

After the Demon Yan Ding reached the perfection of the second pattern, Xiao Wenzi's perception of various spiritual fires was greatly improved, and he could use this to judge the depth of the fire vein, and it was easy to identify a direction and fly over.

"I'll go, it's too big. ”

Xiao Wenzi thought that he had a purposeful action, and it would be easy to find the main fire vein underground.

But he has been walking through the underground magma cave in all directions for several days, and the surrounding area is still an underground karst cave space with little difference.

Xiao Wenzi knew that the fire veins under Millerock Island were vertical and horizontal, but most of them were branches of the main fire veins, and even the fire veins below Millerock City could only be regarded as a large branch.

It is really suitable for high-level cultivators to refine the pill, and the true main fire vein that can allow the fire cultivators of the Yuan Infant Stage to break through in retreat is under the mountain gate of the Thousand Illusion Sect.

In the past few days, he has been moving forward, but he has only just reached the lower edge of Millelith City, and he is still far from the true main fire vein.

"Well, formation fluctuations, I didn't expect that there are formation barriers in such a deep underground, it seems that the Thousand Illusion Sect is not as simple as it seems. ”

While absorbing the increasingly hot earth fire around him to temper the Demon Yan Ding, Xiao Wenzi walked forward according to the guidance, and when he was blocked by a layer of formation light curtain in front of him, he couldn't help but marvel at the strong foundation of the Thousand Illusion Sect in his heart.

Enveloping such a large-scale Xiongcheng, it can also penetrate deep into the underground fire veins and absorb the scorching fire spiritual power as part of the energy to maintain the operation of the large array, this kind of protective city array is by no means something that ordinary array mages can arrange.

Fortunately, Xiao Wenzi studied the Heavenly Array Dao Book intensively, and he was also a late-stage formation mage, and he knew that the depths of the earth-fire magma were the weak points that this array could not cover.

With the help of Demon Flame Ding protection, he can pass through the bottom of the lava.

It is also thanks to the Demon Flame Ding's ability to devour the power of flames to advance, after these few days of continuous strengthening, the third fire pattern on it has begun to appear, and it can barely resist the scorching temperature inside the fire vein below.

Otherwise, even if it is the magic weapon of the Jindan monks, if they want to protect them through safely, they may not be able to succeed.

Passing through the depths of the scorching magma, the formation light curtain was thrown behind, and Xiao Wenzi finally breathed a long sigh of relief.

After a few days, Xiao Wenzi felt that the earth fire in front of him was getting hotter and hotter, if it weren't for the fact that the third fire pattern on the Demon Flame Ding outside his body had already condensed nearly half, he really couldn't stop the invasion of the scorching fire.

"Well, there is another layer of formation, could this be the Thousand Illusion Sect's Protector Array?"

Moving along the wider and wider underground karst cave, Xiao Wenzi didn't know how long it had been, and a layer of light curtain in front of him that was thicker than the Thousand Rock City Protective Array appeared.

This light curtain was not only in the mountain rock and soil, but also in the earth and fire cave, Xiao Wenzi knew that he might have come to the mountain gate of the Thousand Illusion Sect.

The road ahead was blocked by the formation, and there was no shortage of primordial ancestors in the Thousand Illusion Sect, should he take a risk? He was a little hesitant.

However, feeling the powerful aura of fire overflowing from the formation, Xiao Wenzi quickly made a decision.
