As for how high the temperature was in the deepest part of the cave, Ye Fei was a little unimaginable at this time, but one thing he was sure of was that the Foundation Building Realm couldn't stay here too long.

"Zhu Qing..."

"Did you hide your strength when you saw Ye before, or did you have touched the innate threshold in just a few months?" Ye Fei's eyes flashed, and he quickened his pace in unison and walked towards the depths of the cave.

Although the temperature in the cave was high, for Ye Feilai, it was still within his tolerance range.

The voice that came from the depths of the cave was the Zhu Qing that Ye Fei had been looking for, this woman was not in the Zhu family's ancestral house, but she didn't expect to be trapped here.

"You can see when you come in, I don't have much to live." In Zhu Qing's voice, there was a faint desolation at this time.

Ye Fei in the cave couldn't help but be a little moved when he heard this, his speed increased several times in an instant, and he had already reached the cave in a few breaths.

At this time, the temperature in the surrounding air can be described as terrifying, the heat flow visible in the sight is tumbling and twisting in the cave, and the high temperature at the bottom of the cave has inherently exceeded the scope of the foundation building realm.

As Ye Fei's gaze looked, there was a stone wall hall in front of him, and in the center of the hall there was a seal mouth surrounded by a stone plate.

On the stone plates around the seal, countless complex and simple runes are carved, revealing a breath of time, which has obviously been passed down for many years.

The scorching breath in the cave came from the mouth, and Zhu Qing's figure was also standing aside, his face was slightly pale, and he raised his eyes to look at Ye Fei who was moving forward.

It's just that what surprised Ye Fei was that through his observation, this woman's strength was indeed undoubtedly foundational, not as he thought.

"This is the forbidden land of my Zhu family, and it will only be opened on the day of ancestor worship."

"When the descendants of the Zhu family become adults, they will all go through the baptism of this place, so as to obtain the power of the Vermilion Bird Flame." Zhu Qing glanced at Ye Fei, and then his figure moved forward two steps.

Ye Fei nodded slightly, it can be seen that the Zhu family's Vermilion Bird Flame is not innate, and this woman's previous promise to give him the Vermilion Bird Flame should be true.

Without asking too much, Ye Fei immediately stepped forward, his gaze falling on the rune seal in front of him.

"It's a fire vein." Ye Fei's eyes flashed, and through the inheritance memory in his mind, he quickly came up with the answer in his heart.

But what followed was more incomprehension, although this fire vein Ye Fei was the first time he had seen it, as far as he knew, it was just a fire vein, which was not enough to break out such a terrifying high temperature.

Moreover, the fire vein and the flame mastered by the Zhu family, if you think about it carefully, it doesn't seem to have much connection, and the pure power of the Vermilion Bird Flame is obviously much stronger than the power of the flame in the fire vein.

"You actually know the fire vein!" Zhu Qing couldn't help but look at Ye Fei twice at this time, and couldn't help but be a little surprised in his heart.

Looking at the Huaxia martial arts world, except for his Zhu family, there should be no second fire vein in the world, and Zhu Qing also knew what this seal was through the explanations of his elders in the past.

And the young man in front of him recognized the fire vein at a glance, how could Zhu Qing not be shocked.

"I know a little bit about it, but how your Zhu family's Vermilion Flame was generated, Ye is a little unclear." Ye Fei looked up at the person in front of him and said truthfully.

Zhu Qing's face calmed down a little when she heard this, if even the person in front of her knew about this matter, she was afraid that she would doubt her life on the spot.

After taking a deep look at Ye Fei, Zhu Qing at this time didn't say much, turned around and walked in front of the fire vein, it seemed that for the temperature of the fire vein, she seemed to have antibodies, and such a terrifying high temperature was directly ignored by this woman.

On the central stone plate of the cave, Zhu Qing's true qi condensed all over his body, and there was a flash of fire in his eyes, and he suddenly raised his hand and pointed towards the seal in front of him.

A crimson flame erupted from her fingertips, instantly merging into the stone plate seal, and with her movements, the entire cave suddenly trembled.

Immediately after, under Ye Fei's gaze, the stone disk in front of him began to rotate slowly, and the temperature in the air around him rose a few points again.

Ye Fei's eyes flashed, and he suddenly raised his arm, only to see that the storage ring on his index finger did not burst out with bursts of ghost light at this moment, and the wind bead in it became restless.

"There's something in the veins of fire." Ye Fei reacted instantly, using his spiritual power to suppress the Xuan Snake in the Wind Bead, and at the same time looked up at the front.

As he looked over, he saw that the speed of the stone disk in the center was getting faster and faster as time went by, and Zhu Qing's body also flashed backwards and withdrew from the scope of the compass.

Inside the stone plate seal, the sound of magma tumbling came, and then a pillar of fire rose from the ground.

On the surrounding stone plates, the carved runes burst out at the same time, instantly forming an invisible barrier, sealing the pillar of fire in the seal, so that it could not all rush out.

A strange sound came from within the pillar of fire, and it was vaguely visible that some kind of fierce beast was hiding in it, but it was impossible to see its original appearance.

The power of the pillar of fire was still emerging, but it was obviously unable to break through the limit of the stone plate rune, and the temperature on the stone tablet was growing at an indescribable rate at the same time, and a wisp of Vermilion Bird Flame was born immediately.

It seems that the power of the flame generated by the transformation of the stone plate will soon spread throughout the stone plate.

"Naru!" A crisp chirp suddenly spread throughout the cave.

Under Ye Fei's gaze, he saw that all the runes on the stone plate were burned, turning into a huge fiery red firebird, standing with the fire vein seal and letting out a long roar.

Zhu Qing on the side, after seeing the flame bird, the expression on his face became a little more reverent, and he raised his hand and bowed respectfully to the front.

Ye Fei's eyes flickered at the moment, after watching the process of the formation of the Vermilion Bird Flame, he also vaguely understood, and he couldn't help but have some admiration in his heart for the ancestor of the Zhu family, who was able to come up with this method to continue the inheritance of the Zhu family.

"This is a transformation formation, and within that fire vein, there is obviously a fire essence hidden." Ye Fei said secretly in his heart, at this time, his eyes fell on the firebird in front of him, and a smile appeared on his face.

Through the transformation of the formation, as long as you absorb the power of this firebird and use the spiritual power to refine it in your body, you can master the power of the Vermilion Bird Flame.

As for that fire spirit, it is a heaven and earth spirit thing, just like the solid spirit mountain spirit that the old monk sold to him when he was in Yunlan Mountain, and the hidden power in it is unimaginable to ordinary people.

It's just that he wants to subdue it, with Ye Fei's current strength, it is still a little difficult, and this thing is the ancestral inheritance of the Zhu family, he has a good relationship with the Zhu family, and it is a little inappropriate to forcibly subdue it.

"Ye Fei, this is the inheritance of my Zhu family for hundreds of years, and I invite you here this time in the hope that you can help me keep this place." Zhu Qing turned his head, and the expression on his face was extremely sincere.

Ye Fei looked puzzled and glanced at the woman.

At this glance, he couldn't help but be shocked in his heart, and he suddenly found that after the firebird appeared, the breath on Zhu Qing's body seemed to be weak.

"The breath in your body is connected to this firebird?" Ye Fei didn't pay attention to Zhu Qing's words, but asked directly.

Zhu Qing couldn't help but sigh secretly when he heard this, and after nodding slightly, the expression on his face was slightly bitter.

After she glanced at Ye Fei, she pinched the trick in her palm again, and integrated the firebird into the stone plate, and the pillar of fire in the fire vein seal in front of her also returned to the ground at this moment.

After doing all this, Zhu Qing's face regained a little blood, but the true qi in his body was still a little chaotic.

"In this trapped spirit array, the suppressed fire essence is the goal that the generations of the Zhu family masters want to subdue, as long as it is completely refined, there will be no need for the blessing of the formation to inherit the Vermilion Bird Flame in the future." Zhu Qing looked up at Ye Fei and slowly explained.

It was precisely because she wanted to rely on her own strength to completely refine the fire essence some time ago, but she was unexpectedly counterattacked, and now her time is running out.

After listening to this, Ye Fei couldn't help but shake his head slightly.

Even with the strength of his innate realm, if he wants to refine the fire essence, the grasp in his heart is less than three layers, and it is almost impossible for a foundation building realm to control such spiritual objects.

"It's because of Zhu Yuan that you made such a choice, right?" After Ye Fei pondered for a while, he asked in a low voice.

Although he is not very clear about the internal affairs of the Zhu family, Zhu Yuan's sudden return is obviously ill-intentioned, and if he wants to compete with Zhu Qing's strength, it seems that there is only one way to choose.

"Well, he's here for the fire spirits of this forbidden land."

"Tomorrow at ten oon, the power of the stone plate runes in the cave will become weak, and the barrier at the entrance of the cave will disappear with it." After Zhu Qing hummed lightly, the expression on his face darkened a lot, and at the same time nodded in response.

Hearing this, Ye Fei raised his head and glanced at the stone plate in front of him, and when he saw the runes on the stone plate clearly, a strange light suddenly flashed in his eyes.

Although these patterns are extremely ancient, there are extremely detailed records of the way of the formation, within the inheritance of the medical saint, and the runes engraved on the stone plate reminded Ye Fei of an extremely vicious secret method.

"Do you want Ye to help you keep Zhu Yuan and the others out of the cave?"

The expression on Ye Fei's face became a little elusive at the moment, and at the same time he glanced deeply at the woman in front of him.

"I want you to help me kill him, once he enters Taihang Mountain, my Zhu family's hundreds of years of foundation will be ruined." Zhu Qing showed a decisive look in his eyes, stared at Ye Fei and said directly.

As soon as he heard this, Ye Fei was immediately convinced of the thoughts in his heart, and after glancing at the person in front of him meaningfully, he didn't say anything.

I saw that after he was silent for a moment, he slowly shook his head, and then prepared to turn around and leave.

"What do you mean by that?" The expression on Zhu Qing's face was a little more displeased at this time.

She raised her eyes and stared at the back of Ye Fei in front of her, her voice was a little deeper, and the temperature in the air around her had changed significantly at this moment, looking at her appearance, she didn't intend to let her leave easily.
