"However, no matter how good the formation is, it still needs powerful resource support to exert greater power. The cultivation resources of the demon clan are far stronger than those of our human race. I hope you will not hide your secrets!"

Master Xuyun nodded and said.

"Don't worry, we demon clan are not stupid or confused. As long as they are resources needed for the formation, we will provide them with all our strength unconditionally!"

Old Monster Yin Xuan nodded heavily and made a promise.

After expressing their attitudes, both parties began to offer suggestions.

"Mr. Bai has here a set of the 'Heavenly Thunder and Extreme Fire Formation' secretly passed down by his ancestors. It is said to be a powerful formation from ancient times. I am willing to provide it for everyone to use!"

A hidden strong man from the human race wearing a white robe spoke in a deep voice and took out a formation jade slip.

"Heavenly Thunder and Extreme Fire Formation!"

"Hiss! I have seen this ancient formation in an ancient book. It is said that it is extremely powerful. Even in ancient times, it was a famous formation!"

As the words spread, the whole audience was amazed.

The white-robed old man frowned and said, "It's just that the cost of setting up this array is quite high. It requires a variety of extremely high-grade treasures from heaven and earth, which may not be so easy to assemble."

"Without further delay, Brother Bai, please tell me what materials you need. We will collect them immediately without any delay!"

"right!"

The old man in white robe injected spiritual power into the jade slip, and a list of materials with shining spiritual light emerged, densely packed with hundreds of different shapes!

Even though everyone had expected it, they still couldn't help but gasp when they saw the list of materials.

Not only do these materials have many names, but all of them are extremely rare. In addition, the amount of these materials is huge, so it is really expensive to build this array.

However, it was a matter of life and death, so the strong men of the human race and the demon race did not hesitate and took out various materials and piled them together.

In a matter of seconds, almost all the required materials had been gathered, and the speed made the old man in white robe extremely happy!

But after doing the math at one point, his face darkened again and he frowned tightly.

"What's wrong?"

"Brother Bai, is there anything else wrong?"

Taoist Master Xuyun and Old Monster Yin Xuan raised their eyelids and asked quickly.

The old man in white robe shook his head and sighed: "These materials are indeed good, but if you want to set up the sky thunder and fire formation, there are still a few key materials missing!"

"What?"

When everyone heard this, their hearts sank. Hundreds of powerful men present offered treasures one after another, but they still lacked some key materials. The requirements of this "Heavenly Thunder and Extreme Fire Formation" were really high, beyond everyone's imagination.

"Brother Bai, what kind of materials are still missing?"

"With so many of us, can't we just get these last few things together?"

Taoist Master Xuyun and Old Monster Yin Xuan asked with a frown.

"The Heavenly Thunder and Extreme Fire Formation, as its name suggests, uses powerful thunder power and fire spirit power as the core of the formation. The main power of this formation comes from the heavenly materials and earthly treasures with thunder and fire attributes.

Although these materials are of extremely high grade, they are just auxiliary materials at best." The old man in white robe frowned and sighed, his face serious.

Everyone looked at each other, and the atmosphere suddenly became dull.

The Heavenly Thunder and Extreme Fire Formation is the first powerful method used by the human and demon tribes to deal with the mysterious and powerful people in the upper world. If it fails as soon as it is launched, it will be a heavy blow to all the powerful people present and the human and demon tribes.

"Materials with thunder and fire attributes..." Taoist Master Xuyun muttered to himself, thinking intently.

Old monster Yin Xuan also glanced around, his eyes flickering uncertainly.

These two materials are actually not uncommon for a strong person of this level, and can even be said to be quite common.

But obviously the materials that can be used as the core of the "Heavenly Thunder and Extreme Fire Formation" are naturally not ordinary goods.

"Are there fire-attribute materials? Haha, I have some here." An old man in red robe suddenly spoke, his eyes full of pride.

This person is quite conspicuous in his red robe, but the old monster Yin Xuan of the demon clan opposite him is quite different.

His red robe was imprinted with strange flame patterns, and his body had an undisguised aura of fire spiritual power. He seemed to have a very deep cultivation level.

He flipped his right hand and took out a red bead-shaped treasure that was several feet in size. The burning aura it exuded made everyone marvel!

"Hiss! What a powerful fire spirit!"

"What kind of rare treasure is this?"

"Brother Lie, you have such a treasure in your hand, why didn't you take it out earlier?"

Everyone stared at this decision in admiration, and a fellow human race member who was familiar with him even took the opportunity to ridicule him.

The white-robed old man and Xuyun Taoist stood out from the crowd and looked over there, and couldn't help but be shocked by the strong fire spiritual power emitted by this object!

The red-robed old man glanced around and took in everyone's reactions. The pride on his face became more and more obvious, and he was secretly proud in his heart.

"This treasure is called..."

However, before he finished speaking, he was interrupted by the old man in white robe.

"If I read it correctly, this thing should be the 'Fire Lin Dan' that appeared on the 'Lingluo Continent' hundreds of years ago, right?" The old man in white robes said in a deep voice with a flash of light in his eyes.

"Haha, I didn't expect Brother Bai to be so knowledgeable about goods. Yes, this object is exactly the fire-attributed spiritual object 'Fire Lin Dan' that appeared on Lingluo Continent hundreds of years ago and caused quite a stir!"

The red-robed old man nodded and laughed, his pride no longer concealed.

The strong men of the demon race didn't know much about this object. They only knew that it was a fire attribute treasure. When they heard the strong men of the human race talking about it, they couldn't help but secretly marvel.

The elders and powerful men of the human race who knew about this all opened their eyes wide, and their eyes were full of fire.

But while everyone was exclaiming and discussing, the old man in white robe shook his head and sighed.

"not enough!"

"What?"

"not enough?"

As soon as the white-robed old man finished speaking, everyone immediately aroused doubts and surprise.

Is such a rare fire attribute treasure of heaven and earth not enough to serve as one of the core elements of the "Heavenly Thunder and Extreme Fire Formation"?

"Brother Bai, are you kidding me?" The red-robed old man frowned, obviously unhappy.

To be honest, he didn't want to take out this treasure.

The "Heavenly Thunder and Extreme Fire Formation" is powerful, and the various materials used must also consume a lot of money. As long as the best things are used in this formation, their value will eventually be exhausted and become waste.

But the "Fire Lin Dan" that he was so proud of and regarded as a treasure in his family was so scorned by the white-robed old man, which really made him very unhappy and even a little annoyed.

Hiss!

Many powerful human beings were greatly surprised when they heard this. Many people even felt that the old man in white robe was being mysterious.

If rare treasures such as "Fire Lin Dan" are not enough to serve as the center of the "Heavenly Thunder and Extreme Fire Formation", then what kind of fire attribute treasure is needed to take on this important task?
