There is a tiger on each side, and two tiger heads are in the cauldron, facing each other.

The top cover of this small tripod is carved with a dragon head, roaring, and looks extremely ferocious.

The dragon mouth is wide and you can see the situation in the tripod.

Old An smiled at Chen Feng and said, "Chen Feng, I want to refine a pill now. Please watch my movements carefully."

Chen Fengzheng focused his head and stared at him without blinking.

The dark veteran Aoki King Ding placed it on the ground, and then the soul body was suspended in front of the Aoki King Ding.

With a gentle stroke of his right hand, ten herbs fell into the Qingmu King Cauldron.

Old An looked at Chen Fengfeng and said lightly: "The medicinal materials cannot be added at once, but they must be added one by one."

"If you are a beginner like you, you can add it in the same way, but like me, you can add it in batches."

As he said that, he stretched out his right hand and suddenly a cluster of flames appeared on his hand.

This cluster of flames turned out to be pure black!

As soon as the flame appeared, Chen Feng felt that the temperature in the whole room suddenly increased to hundreds of degrees.

Chen Feng was extremely shocked.

He has also been exposed to high temperatures of thousands of degrees, but those flames are absolutely impossible to have such an effect.

Doesn’t this mean that the temperature of this cluster of black flames has exceeded tens of thousands of degrees?

This flame, about the size of a fist, hangs in the palm of Dan Lao's palm and keeps jumping and rising.

As soon as Chen Feng touched the flame, he felt like his eyes were about to be burned. He quickly moved his gaze away and was shocked:

"This flame is so evil. Not only is it extremely hot, but it is also pitch black in color, it seems to be about to devour everything!"

He asked, "Old An, what is this?"

Old An smiled and said, "My cluster of flames is a kind of mysterious fire, called Hell's heartless fire!"

"Hell no heart fire?" Chen Feng muttered a few words, then asked, "Xuanhuo, what is that?"

"What is hell without heart fire?"

An Lao smiled and explained: "Little guy, it's normal for you to not understand these things."

"Don't worry, I'll tell you in the future."

Then he explained: "The mysterious fire is some extremely rare flames that are born in the world, inheriting the spiritual energy of heaven and earth, and contain the essence of the sun and the moon."

"These flames grow and grow on their own, and even have a hint of spirituality, and only grow in extremely dangerous and rarely visited mountains and lakes!"

"Some mysterious fires have stronger origins. They may be carried by meteorites outside the sky, or they may be caused by undersea volcanic explosions and self-growth."

"In short, all the mysterious fires are extremely powerful and have divine powers."

"And, each temperature has reached at least tens of thousands of degrees!"

"Generally speaking, alchemists have to use their own qi to generate flames, which is why alchemists need to have the two attributes of fire and wood."

Old An paused and continued, "And the alchemist can distinguish the flames generated by the qi from the color."

"Generally speaking, the lowest level is the red flame, and above the red flame is the orange flame."

Chen Fengfu came to his heart and asked, "This is a flame generated by his own qi. So, if you touch Xuanhuo, can you incorporate Xuanhuo into your body?"

"Haha, you little guy, are really a tutorial person, very smart!"

An Lao smiled and said, "Yes, Xuanhuo can be included in the body by the alchemist. If you really subdue a Xuanhuo and let it be used by me, the effect of the refining medicine can be increased at least several times."

"The mysterious fire is not comparable to the flames generated by the Gangqi."

"However, the temperature of the Xuanhuo is extremely high and has all kinds of power. The same characteristic is extremely violent and unruly, and it will never be easily subdued by humans."

"You think, at a temperature of tens of thousands of degrees, even the strong metal can melt, let alone the human body!"

"How can the human body be so fragile that it can be tolerated under the burning of such flames?"

"At the same time, the mysterious fire is extremely rare."

"So, although most alchemists want to have Xuanhuo and many people are looking for it, they may not be able to find it in their entire lives."

"And even if you can find it, ninety-nine percent of the possibilities will be to swallow the mysterious fire, but instead it will be melted into ashes by the mysterious fire."

"So, even in the world of alchemists, Xuanhuo is extremely rare! There are extremely rare alchemists with Xuanhuo!"

Chen Feng was dazzled and fascinated by hearing it.

Old An's words brought him a magnificent world of alchemists.

Chen Feng asked, "Old An, isn't the hellless fire in your hand a very powerful mysterious fire?"

Old An nodded and said, "That's right, my heartless fire in hell is a famous mysterious fire on the list."

Before Chen Feng could ask, he explained:

"Ten thousand years ago, in the world of alchemists, several of the most powerful beings had combined all the known mysterious fires in the world and ranked a list of mysterious fires."

"There are a total of 100 different types of mysterious fire on the Xuanhuo List."

"And my hell is in the 97th place!"

When he said this, his face showed a proud look.

Obviously, it is already a very proud thing to be able to get a famous Xuanhuo on the list.
