Tiangong's analytical ability is a very terrifying existence.

Just at the peak of the Great Furnace, through the analysis of the surrounding environment, the power of the Earth Fire Explosion was obtained.

Thus, according to this, the condition of the underground fire spirit vein was obtained.

What Zhou Xuantong has to do now is to reach the location of the fire spirit vein.

On this trip, Zhou Xuantong did not let anyone accompany him, only in this way can he use the Thunder of Truth at will.

What Zhou Xuantong has to do now is just to move forward.

The Thunderbolt of Truth emerges, opening the way ahead, breaking down the earth and stones, and then compressing and reconstructing them into a walking ladder, a solid wall that will not collapse.

The direct metal of this mountain stone is also gazed into long nails, pierced into the soil, and stabilized.

If someone is accompanied, Zhou Xuantong has to show his acting skills and take turns to smash it with a hammer.

Tired!

Constantly walking down diagonally, the speed of Zhou Xuantong's spiritual energy loss was very huge, and the high-grade spirit stones obtained from Danyi Sect were decomposed by him one after another, extracting spiritual energy, and incorporating them into his body.

The process of opening up this underground corridor is also a process of cultivation for Zhou Xuantong.

In its dantian, it was stimulated, and the source of spiritual energy continued to expand, and the water in the spiritual energy pool in the dantian was gradually condensed.

Repair is a rising tide and a boat rises.

However, the spiritual energy contained in the high-grade spirit stones is so terrifying, and the growth rate of Zhou Xuantong's strength is still slow.

"The speed of my realm ascension is inevitably too slow, right?" Zhou Xuantong frowned, and couldn't help but think about the Heavenly Dao.

"Master, you are the body of the Heavenly Dao, and it is normal for your cultivation to improve slowly. Tiangong reminded, "But your combat power, in the same realm, it is difficult for anyone to match it." ”

"Actually, among some strange heavenly and earthly treasures, the aura obtained by decomposition will be better for the improvement of cultivation. ”

"If possible, the host can keep an eye out for news in this regard. ”

Zhou Xuantong remembered in his heart and continued to go underground.

It took half a day, and Zhou Xuantong finally clicked on the location of the fire spirit vein.

At this moment, Zhou Xuantong's location is the end of the original fire gushing out of the crack.

When the fire broke out, it had collapsed.

The moment he opened the place where the fire spirit vein was located, the scorching earth fire was already surging violently.

Laugh at!

The Thunder of Truth instantly turned into a thunderous power grid in front of Zhou Xuantong, covering the scorching flames.

Zhou Xuantong's eyes suddenly lit up, controlling the Thunder of Truth, reconstructing the earth fire, constantly compressing and condensing.

Under the oppression of the Thunder of Truth, the surging earth fire was like substance, and finally the vermilion hot spar fell in the cave where the fire spirit vein was located, exuding high temperature.

"Fire Spirit Stone!" Zhou Xuantong stretched out his hand to probe, and grabbed the vermilion high-temperature spar, wrapped in the Thunder of Truth, and suspended it in the palm of his hand.

"Shangpin?" Looking at the fire spirit stone in front of him, Zhou Xuantong couldn't help but sigh, "I didn't expect that, unintentionally, I found a way to solve this extra fire." ”

At this time, Zhou Xuantong looked up and looked ahead, and the entire huge crypt was full of raging flames.

Originally, Zhou Xuantong's plan was to vent this earth fire and then repair the earth fire.

Unexpectedly, he could use the Thunder of Truth to construct the earth fire into a fire spirit stone.

There is a big difference between whether spirit stones have attributes or not.

Pure spirit stones, the scope of application is very large, belongs to hard currency.

The spirit stone containing attributes has a small range of applicability, and the effect is better in specific situations.

Just like this fire spirit stone, it is very easy to use for alchemists or refiners.

Thinking of this, Zhou Xuantong opened his hands, the aura in his body surged wildly, and the Thunder of Truth burst out with all his might, and began to compress and reconstruct this spiritual fire.

The reddish high-temperature spirit stones continued to condense from mid-air, and finally fell to the ground, and the number of surging flames in the crypt became more and more rare.

Soon, in front of Zhou Xuantong, there were already a mountain of fire spirit stones piled up.

The surging flames in the crypt also disappeared completely, revealing the true face of the fire spirit vein.

In the stone wall of the huge crypt, a huge jade stone with a warm and pale red color is like a red dragon lying in it.

The fire spirit veins absorb the surrounding spiritual energy, and discharge a rich fire attribute spiritual energy, which is dispersed in this crypt space.

As the concentration continued to increase, these fire aura changes turned into earth fire, filling the space, and finally surging upwards along the cracks.

Zhou Xuantong waved his hand and put the fire spirit stone into the acceptance ring, and these can be exchanged for a batch of high-grade spirit stones with Danyi Sect at that time.

Ten fingers crossed, stretched for a moment, Zhou Xuantong took out the refining materials from the acceptance ring, and began to get busy.

First of all, ternary iron is indispensable, and this material developed by Zhou Xuantong himself is used to construct the Earthfire Corridor.

At the same time, Zhou Xuantong also specially developed a unique material, Yan steel.

This is a new material made by him using hot stone and forged steel in different proportions.

This substance has a very high resistance to high temperatures, and can even be exposed to high temperatures to feed itself.

The process of being scorched by high temperatures is also the composition of smelting, and wrapping the fire spirit veins with flame steel will only make them stronger, and will not collapse over time.

Inside the crypt, the azure thunder and lightning illuminated it, and Zhou Xuantong used flame steel to completely seal this fire spirit vein inside.

As for the rest of the buried part of this fire spirit vein, leave it alone.

It is enough to have such a section of aura catharsis as a fire spirit vein.

The ground fire is enhanced, and it is very simple.

You only need to construct the aura circuit into a spirit gathering array that you learned when you study on Earth.

"Here, it's called Yangang Basement. Zhou Xuantong touched his chin and looked at the closed steel box of the Yangang structure in front of him with satisfaction.

Then, Zhou Xuantong constructed it again on the basis of the Spirit Gathering Array.

With everything done, Zhou Xuantong continued to construct the Earth Fire Corridor, so that the Earth Fire could be controlled freely and erupt at will.

First of all, what needs to be done is to complete the earth fire corridor of the giant furnace peak.

Zhou Xuantong walked leisurely, and the refining materials from which the receiving rings were kept flying out.

Under the Thunder of Truth, many materials instantly decomposed and reorganized, turned into metal pipes, pierced into the earth and stones, and followed Zhou Xuantong to walk upwards and continue to extend.

Zhou Xuantong returned to the ground and had already appeared in the center of the Giant Furnace Peak Square.

Here, he has already cast a large hall by him.

In the center of the main hall, there is also a flame furnace made of flame steel, which is used for precise control of the earth fire.

The Earthfire Corridor is connected to the bottom of the furnace, and above the furnace, there are many pipes that extend out, piercing into the ground, extending in all directions.

When I walked out of the main hall, there was already a group of people outside the hall, waiting quietly.

"Gongzi Zhou, this ......" As soon as Qi Shan spoke, he was interrupted by Zhou Xuantong waving his hand.

"Come with me!" Zhou Xuantong beckoned and walked straight towards an alchemy room on the side.

Qi Shan and the other elders looked at each other, and they all followed into the alchemy room.

"This!" When they entered it, they were pale with fright, and they couldn't stand steadily.
