Yue Yan nodded slowly and said, "If I'm not mistaken, the Red Refining Fire Vein was originally not just a fire vein, it should be formed by the fusion of two spiritual veins, one of which is a metallic spiritual vein, and it does not have fire attribute spiritual power. But coincidentally, next to this metallic spirit vein, another fire attribute spirit vein was born!"

"Golden Spirit Vein, Fire Spirit Vein, so the Red Refining Fire Vein is formed by the fusion of these two Spirit Veins?" Ye Chen took a deep breath, and a strange light flashed in his eyes.

It was the first time he had heard about the fusion of spiritual veins, and he couldn't help but be a little shocked!

"That's how it should be! The golden spirit vein has a heavy breath and slightly poor activity, and rarely changes in itself, while the fire spirit vein is restless and extremely violent, often swimming along the earth's veins, devouring and fusing everything it encounters. Obviously, after this fire vein spirit came here and encountered the golden spirit, it devoured and fused it, thus reducing its restless attribute and adding a trace of heaviness, and over time, this red refining fire vein was formed here!" Yue Yan took a deep breath and explained intently.

Ye Chen quickly understood, and finally knew why the core of the Red Refining Fire Vein was filled with this pure golden flame!

"This golden flame not only contains terrifying fire spiritual power, but also integrates amazing metallic spiritual power, if it can be absorbed, it will be extremely beneficial to one's own cultivation. Yue Yan nodded heavily and said solemnly.

"It's a pity that I am an innate spiritual fire bloodline, and I can't absorb the metallic spiritual power in it, and even if I forcibly absorb it, I can't fuse it perfectly. Yue Yan shook his head and sighed, very regretful.

"Metallic spiritual power!" Ye Chen's eyes moved when he heard this, and a hint of surprise flashed in his heart.

He has five kinds of spiritual power in his body, so it is naturally not a problem to absorb metallic spiritual power.

"Yes, that's good!, I didn't expect to encounter such an unexpected joy when I entered the Red Refining Fire Vein!" Ye Chen took a deep breath, excited in his heart.

Without much hesitation, they soon sat suspended in mid-air above the golden flames and began to retreat.

Yue Yan urged the innate spiritual fire bloodline, and conjured up a red fire dragon circling around his body, absorbing the fire spiritual power in the golden flame with all his might.

However, every time he absorbed a trace of fire spiritual power, a golden light would appear in the void, hovering for a moment before merging into the surrounding golden flames.

This is the metallic spiritual power that Yue Yan can't absorb, and it is also the metallic spiritual power contained in the golden flame.

After countless years of evolution, these metallic spiritual powers are no longer ordinary metallic spiritual powers, and have undergone great changes and become very active.

Moreover, under the influence of the metallic spiritual power, the fire spiritual power of the Red Refining Fire Vein was no longer as manic as it was originally, and it had a deep charm.

This is also the reason why Ye Chen and Yue Yan were able to cultivate here safely, otherwise, if it was a pure spiritual fire leyline, the fire spiritual power would be much more violent than it is now, even if they barely came here, I am afraid they would not be able to cultivate calmly.

In order to avoid interfering with each other, Ye Chen and Yue Yan were hundreds of zhang apart, each levitating in the void, sitting cross-legged and cultivating.

There was a five-element diagram suspended under Ye Chen's body, and the whole person seemed to be held up by the five-element diagram and suspended in the void.

The golden flames below continued to scorch this five-element diagram, however, after these golden flames came to the bottom of the five-element diagram, they were torn into two by the rapidly rotating five-element diagram, and two different spiritual powers were separated and fused into the five-element diagram.

One of these two kinds of spiritual power is the extremely pure metallic spiritual power, and the other is the extremely hot fire attribute spiritual power.

I have to say that the two spirits contained in the core of the Red Refining Fire Vein must be extremely pure, even far beyond Ye Chen's expectations.

"It's really embarrassing that the Yu family clan has occupied the Red Refining Fire Vein for so many years and has not been able to develop its greatest potential!" Ye Chen sighed as he cultivated.

If there is one person in the Yu family who can give full play to the potential of the Red Refining Fire Vein, I am afraid it will be enough to change the pattern of Tianyun City and even affect the entire Tianyun Kingdom.

But it's a pity that the Yu family is not an innate spiritual fire bloodline, and the Yue family, which has an innate spiritual fire bloodline, has completely decayed for various reasons.

Therefore, although there were such two powerful fire veins in Tianyun City, there was still no extremely strong martial artist who cultivated the fire attribute exercises.

The Five Elements Diagram rotated rapidly, continuously sending the two spiritual powers contained in the golden flames into Ye Chen's body.

Ye Chen used all his strength to operate the Heaven and Earth Reincarnation Technique, and collected these spiritual powers, and the cultivation aura around his body began to climb steadily.

After these days of retreat in the Red Refining Fire Vein, the power of the spiritual fire in his body has been greatly improved, especially the three-element true fire has reached a certain subtle realm, although it is still a little short of the evolution of the spiritual fire, but it already has unprecedented spiritual power.

And after coming to the true core of the Red Refining Fire Vein, which was where this golden flame was, he was able to truly improve his cultivation.

At this moment, he could absorb two kinds of spiritual power with all his strength, but Yue Yan could only absorb fire attribute spiritual power, and the cultivation speed of the two of them just flipped over.

Ye Chen's cultivation aura grew rapidly, and although Yue Yan's cultivation aura was not slow to improve, it was obviously not as fast as Ye Chen, who absorbed two spiritual powers at the same time.

However, Ye Chen was not in a hurry to impact the cultivation realm, but while urging the Five Elements Diagram to absorb the two spiritual powers, he silently condensed his own exercises.

The exercises he possesses, the Thunder Flame Palm is mainly based on thunder attributes and fire attributes, and its power is very powerful.

Now, after absorbing enough metal spiritual power and fire spiritual power, this set of exercises has been re-condensed, and the power has been extremely significantly improved, and it can even be said that it has been reborn from the original exercises.

In addition, his Purple Gold Holy Body had been difficult to improve significantly recently, and the reason was because there were no extreme conditions for him to temper his physical body.

But in the Red Refining Fire Vein, he found this kind of opportunity.

As the saying goes, real gold is tempered by fear of fire, and the powerful spiritual fire that fills the void here can just allow him to temper the purple gold holy body and make it elevate again.

Ye Chen ran the exercises with all his might, and a purple-golden light rose from his body.

Under the infusion of golden spiritual power and the baking of fire spiritual power, his purple gold holy body also began to steadily improve, and there was an entry that he had not seen for a long time.

"Very good, very good! I didn't expect that the Red Refining Fire Vein could also have a lifting effect on the Purple Gold Holy Body, this time it was really the right time!" Ye Chen took a deep breath, excited in his heart.

He was still extremely pleasantly surprised by this unexpected opportunity.

If he hadn't completely turned against Yu Tian, he probably wouldn't have had this opportunity to come into contact with the true core of the Red Refining Fire Vein.

His Purple Gold Holy Body had already reached the sixth layer, but if he wanted to break through the seventh layer, he was afraid that it was far away.

But now, he sees an opportunity for a breakthrough.
