The Doctor of the City goes down the mountain

Chapter 2494: Dan Fire has nine changes!
Lin Dong took a deep breath and stepped firmly into the area of ​​underground fire that was revered by the world.

This is where nature's most primitive and wild power is displayed. The blazing flames are like roaring beasts, devouring all living creatures that dare to approach.

The underground fire originates from deep within the earth's core and contains the chaotic power from the beginning of the world. Its temperature is high enough to melt gold and stone and burn all things.

They may flow like thin threads or surge like torrents, and each strand exudes heart-pounding heat and destructive power.

Lin Dong was well aware of the horror of the underground fire, and immediately activated the Holy Dragon Blood Body in his body.

"Boom!" After using the Heavenly Realm Dragon Blood Holy Body, the whole body seemed to be covered with dragon scales, and the defensive power instantly became amazing.

Stepping into the underground fire area, the terrifying high temperature could no longer cause any harm to Lin Dong.

However, as he went further in, Lin Dong could feel that the temperature of the underground fire was getting higher and higher.

"The temperature here is comparable to my purple gold elixir fire!" After walking for a distance, Lin Dong couldn't help but exclaim in his heart.

This was not the hottest place in this area of ​​underground fire. However, the temperature here was already comparable to his purple gold pill fire.

"Keep going forward. The Earth Soul Beast should be in the center of the Earth Fire Area. The illusion encountered by the Dragon Group members before was caused by it!"

"Earth soul beasts live in the earth fire and cultivate through the earth fire. They refine a terrifying golden body of fire, at the level of a demon king. Their physical defense can reach the level of a demon emperor."

"And it's not just physically strong, it also has innate control over soul power. Just like the spiritual power cultivators among human warriors, it can create illusions."

"Of course, because they don't have the same wisdom as humans. So they generally don't have any spiritual power training methods. They can only use soul power to simply release some illusions. They can't use various spiritual power methods like real spiritual power practitioners..."

In the dragon ring space, the voice of the witch god sounded again, communicating with Lin Dong continuously.

She knew a lot about this earth soul beast. Because she knew that the refining of Nirvana Pill required the "Soul-Fixing Pearl", she remembered this knowledge very clearly.

Lin Dong nodded and continued on his way.

After walking for a while, Lin Dong sensed that the temperature of the underground fire area here actually exceeded that of his purple gold elixir fire.

He knew very well that such an environment was a perfect opportunity for him to improve his Dan Huo and even his own strength.

As his mind moved, a wisp of purple-gold flame burned quietly in his body. That was the source of the purple-gold elixir fire that he had condensed after going through countless hardships since he started practicing.

This is the second of the nine changes in Dan Fire!
As his alchemy skills improved and he read more ancient books, he also understood the complete qualities of the alchemy fire.

There are nine grades of alchemist's elixir fire.

This is what alchemists often say, "Alchemy fire has nine changes"!
The first transformation of Dan Huo is the ordinary Dan Huo. The temperature of the newly condensed Dan Huo is higher than that of ordinary gunpowder, but not as high as that of molten magma.

The second transformation of Dan Fire is Purple Gold Dan Fire. This is the second grade of Dan Fire. At this level, the temperature is terrifyingly high, surpassing molten magma.

If performed by someone with great strength, it could even burn an Earth Realm warrior to death instantly!
Ordinary means such as water flow and mud and sand cannot extinguish the purple gold elixir fire.

When used to refine pills, the effect will be much better than the first transformation of the pill fire. Generally speaking, the success rate of the purple gold pill fire in refining pills of the third grade or above will be several times higher than that of ordinary pill fire.

The higher the grade of the alchemy fire, not only will it increase the success rate of alchemy, but it will also make the refined pills have higher quality.

In addition, the higher the grade of the alchemy fire, the more pills can be refined in one furnace.

Therefore, every alchemist will pursue higher grade alchemy fire.

Danhuo is like a scalpel in the hands of Western medicine, acupuncture in the hands of Chinese medicine, and the hairdressing tools in the hands of a barber... Of course, the higher the grade, the better!

At this moment, Lin Dong condensed the origin of the purple gold pill fire. The flames danced, showing its extraordinaryness.

But although it is extraordinary, it still seems small in front of the vast underground fire.

"Let me use this earth fire as a furnace to temper my purple gold elixir fire!" Lin Dong said secretly in his heart.

He now had some sense, knowing that his purple gold fire was on the verge of upgrading. Because the edge of the purple gold fire had already undergone some transformation. The color was rendered with a light layer of colored glaze.

It's like there is a layer of film on the edge of the flame!

Lin Dong knew that the third transformation of Danhuo was called Glazed Jade Fire!

The color of this glazed jade fire is a crystal clear emerald green.

Like the purest glass gem in the deep sea, the light flows with a fresh and unworldly breath.

Now, the outermost surface of the Purple Gold Pill Fire has a light glazed color, indicating that it is on the verge of the third transformation.

"As long as we use the earth fire here to temper it, maybe the purple gold pill fire can be completely transformed into the glazed jade fire. Complete the leap from the second transformation to the third transformation of the pill fire!"

Thinking of this, Lin Dong did not hesitate at all and prepared to refine the purple gold elixir fire immediately.

He mobilized all his spiritual power and slowly released the purple gold elixir fire, allowing it to come into contact with the surrounding earth fire.

As soon as it came into contact, the Purple Gold Pill Fire felt unprecedented pressure.

The violent and blazing fire of the underground fire seemed to devour it completely. But Lin Dong did not retreat. Instead, he increased his spiritual power output, guiding the purple gold elixir fire to shuttle and wander in the underground fire to fight against it.

As time went by, the purple gold fire began to change. It was no longer the single and pure purple gold color as it was at the beginning, but gradually integrated the elements of earth fire, the color became deeper, and it seemed as if there were dragons and snakes dancing in the flames, revealing an ancient and mysterious atmosphere.

The purple gold elixir fire was originally only covered with a layer of colored glaze on the surface, but the entire center of the flame was undergoing earth-shaking changes.

"Huff, huff, huff~~~~" The entire earth fire seemed to have turned into a furnace, tempering the purple gold elixir fire condensed in Lin Dong's palm.

"Colored glazed jade fire, transform!" With a low shout, Lin Dong suddenly opened his eyes, and two flames flickered in his eyes.

He quickly formed seals with his hands, and each seal was precise and accurate, as if he had practiced it in his mind thousands of times.

As the seal was completed, the inner flame of the purple gold elixir fire in his palm began to vibrate violently, and the color gradually changed from purple gold to a strange emerald green.

This emerald green color is not something you see commonly. It is crystal clear, like the purest glass gem in the deep sea, or like the tender leaves just born in spring, full of vitality and infinite possibilities.

"Finally, the transformation has been completely completed. The purple gold elixir fire has become the glazed jade fire!"

The glazed emerald fire in his heart gradually grew stronger under Lin Dong's control, and finally turned into a emerald green fire dragon that surrounded him, forming a sharp contrast with the raging ground fire around him.

Looking at the glazed jade fire, it turned into a jade-green fire dragon, surrounding him. Lin Dong smiled slightly, he knew that he had succeeded.

He successfully refined the second transformation of the Pill Fire, the Purple Gold Pill Fire, into the more powerful and purer third transformation of the Pill Fire - the Glazed Jade Fire!
He originally wanted to use the Glazed Jade Fire to refine a pill to see the effect of the Glazed Jade Fire. However, at this moment, perhaps because Lin Dong had activated the Earth Fire to refine the Pill Fire, he attracted the attention of the Earth Soul Beast in the center of the Earth Fire.

In the center of the underground fire, there was an earth-shaking roar.

And under this roar, the entire underground fire area began to roll, as if magma was about to erupt.
