"Nether Fire!"

After Wu Tianyi was in a trance, he cried out in a lost voice.

The three invigilators were stunned.

Alchemists basically use fire to refine medicines.

And the quality of the flame determines the quality of the elixir.

The flames condensed by ordinary alchemists with energy are the most ordinary energy fires.

The Five Elements Flames collected by some alchemists from the Five Elements can deal with medicinal materials with different attributes, and the quality is higher than that of ordinary fires.

But other than that, they didn't know anything else.

So the three of them all looked at Wu Tianyi suspiciously.

Wu Tianyi explained, "In addition to the ordinary flames and the Five Elements flames that you know, there are also the three divine fires of the highest quality: Heavenly Thunder and Earth Fire, Chaos Yuan Fire, and Nether Ghost Fire.

However, all three types of flames are unattainable.

For example, the thunder and earth fire are flames formed under extremely harsh conditions after lightning strikes the magma in the volcano.

Moreover, after this kind of flame is formed, it can only exist for a short time, and even if the alchemist encounters it, he will use it to refine the elixir.

But it is also impossible to take this flame to its own use.

After all, this flame can only exist for a short time.

Speaking of Chaos Yuan Huo, it is even rarer.

It is said to be the Mars formed during the Great War of the Ancient Gods and Demons and the opening up of the fairy world.

It's just that almost no one has ever seen this Chaos Elemental Fire.

Finally, this kind of ghost fire is very common: the ghost fire that is often seen on the grave at night is very close to the ghost fire. But this isn't really Nether Fire. The real Nether Ghost Fire is produced by those zombies whose strength has reached its peak and can kill any martial saint in an instant, and after death, the phosphorus in the body is mixed with the energy in their body.

Therefore, the Netherfire is controlled by the zombies. ”

When he said this, Wu Tianyi sighed:

"The predecessor of the God of Medicine once inadvertently caught a zombie and used the zombie's ghostly fire to refine a top-grade ninth-grade elixir. It was also the only top-grade ninth-grade elixir in our entire history of the immortal realm. Later, the predecessors of the God of Medicine wanted to refine the zombie's ghost fire for their own use, but unfortunately, the zombie had corpse poison in its body, and if it was refined, it would inevitably be poisoned by the corpse, thus becoming a zombie.

Moreover, the ghost fire can burn people's souls, or rather, people's minds. This requires the alchemist to have a strong mind, and this mind must be extremely condensed. But it is almost impossible for humans to reach that level of mind.

In the end, the medicine god seniors could only give up. ”

When they said this, the three invigilators were amazed.

"But how can Zhang Fan refine the Nether Ghost Fire?"

"How did he refine the Netherworld Ghost Fire, which even the predecessors of the Medicine God couldn't refine?"

"This guy...... It's incredible! ”

Wu Tianyi also said: "How did he refine, only when he finished the exam, we went to ask him." Now, let's take a look at how he actually refined three ordinary materials into elixirs. To be able to refine ordinary materials into elixir, I'm afraid only Nether Ghost Fire can do it. ”

At this time, Wu Tianyi's anger and disdain for Zhang Fan in his tone had long been swept away.

Instead, there is anticipation.

He seemed to have long forgotten how he reprimanded Zhang Fan before.

Zhang Fan's slap in the face came too quickly.

There was no refining medicine at all, and as soon as the flames came out, Wu Tianyi softened most of them first.

At this time, I saw the blue-white flame in Zhang Fan's hand, which was heated under the medicine pod.

Soon, I saw that the entire medicine pod was covered with a layer of hoarfrost.

Then, the hoarfrost grew thicker and thicker, turning into a layer of ice.

The entire pod, including the materials inside, was wrapped in ice.

Seeing this scene, everyone was puzzled.

"After the flame is heated, not only is the medicine pod not hot, but it freezes, what's going on?"

"I don't know. His blue-white flame looked strange. ”

"Hell, it's the first time I've seen a flame freeze things."

Yao Lao looked at the big screen thoughtfully.

In the invigilation room, the three invigilators all looked at Wu Tianyi, waiting for Wu Tianyi to explain.

Wu Tianyi thought for a moment and said, "I once read the "Theory of Fire" written by the predecessor of the God of Medicine. It says that this ghostly fire is cold on the outside and hot on the inside. The outer layer of blue is cold, and the inner layer of white is hot. Looking at Zhang Fan's appearance, I am afraid that he will refine according to the fifth situation mentioned in his first question answer. ”

The three men listened and remembered.

The fifth situation mentioned by Zhang Fan refers to refining under extremely cold conditions.

Although it is not an extremely cold condition now, this Nether Ghost Fire Outer Flame is cold, and he wants to use the Nether Ghost Fire to create an extremely cold condition.

Sure enough, in the picture, the ice layer created by the Nether Ghost Fire had frozen the entire medicine pod into a large ice lump with a diameter of one meter.

It was only at this time that he moved his hand a little closer to the medicine pod, so that the inner flame inside could touch the pod.

At this time, I saw that the center of the medicine pod began to melt slowly.

Through the detection of the instruments at the scene, it can be seen that although the ice outside the medicine pod has not melted, the middle has melted.

The three herbs began to be slowly heated.

According to Zhang, the ice freezes the toxins in the material to a dormant state.

Slow heating, just like boiling a frog in warm water, will slowly kill 90% of the toxins in the herbs, thus greatly increasing the efficacy of the medicine.

He Shi finally spoke at this time: "Now that Zhang Fan is using the Netherworld Ghost Fire, this effect will be much improved. It is likely that it will kill more than 99% of the toxins in the herbs, so that the efficacy of the medicine will be much improved. Maybe it can be more than 50 times the original! ”

At this time, the picture that people see is amazing.

Outside was a layer of ice, but inside the ice there seemed to be a faint flame burning quietly.

This process lasted about five minutes.

The ghost fire in Zhang Fan's right hand was finally extinguished, turned into energy and returned to Zhang Fan's body.

Wu Tianyi and the three invigilators, when they saw Zhang Fan's ghostly fire extinguished, they all felt reluctant.

This kid can actually master the Netherworld Ghost Fire, one of the three magical divine fires, which is really envious!

In the examination room, in front of Zhang Fan, there was still the ice lump with a diameter of one meter.

It's slowly melting.

But Zhang Fan didn't wait for him to melt slowly, and gently tapped his right hand on the ice twice.

Click-

Dozens of cracks suddenly appeared in the ice.

In the end, there was a bang, and it cracked into a small block of Xiaoice.

What appeared in front of everyone's eyes was a drop of turquoise liquid.

And this liquid medicine has a turquoise light shaking on it.

The light is so dazzling that it makes people's eyes sting.

Seeing this, everyone gasped: "Top-grade elixir!" ”
