The Strongest Prodigy Doctor

The Cold Fire, like the Illusory Fire, is the first wisp of fire energy in the world, and upon shattering, it produces a fragment.

Moreover, the subsequent process is like the Illusory Fire, descending from the sky and landing here, although it wasn't called the Zero-Degree Plain at the time. It was just a plain, and then the Cold Fire froze the surroundings.

Of course, a single Cold Fire doesn't possess such a great ability to transform an environment into a forbidden zone. It was only after subsequent tectonic movements, where a mountain collapsed during the earth's movement and precisely struck the Cold Fire. After a series of movements, the Cold Fire used its freezing power to create a vast ice layer in the instant the mountain pressed down, forming the space within the ice crevice today.

Following that, after long years, this place saw a return to its spring bloom conditions. After all, the Cold Fire had already gone underground, so while the surface might feel somewhat refreshing, the temperature wasn't quite so low anymore.

Ultimately, several thousand years ago, the Zero-Degree Plain experienced a calamity, transforming it into today's Zero-Degree Plain.

Meanwhile, the Cold Fire itself, a gradually weakening flame, began to recover as the outside turned into the Zero-Degree Plain.

The Zero-Degree Plain also changed from initially maintaining a constant temperature of minus 273.15 degrees to today's average of minus two hundred degrees. This temperature was precisely used by the Cold Fire to repair itself.

The Cold Fire, or the Low Temperature Fire, exists due to the fact that flames vary temperature-wise under different conditions. The Cold Fire represents low temperatures, but since it is merely a fragment of flame, its temperature never changes.

The Cold Fire continuously maintains its low temperature and keeps dropping, eventually reaching absolute zero, at minus 273.15 degrees, or possibly lower. Of course, should the Cold Fire's temperature rise, it signifies the extinguishing of the Cold Fire. When the temperature finally rises to zero, it marks the day the Cold Fire extinguishes.

If the Cold Fire extinguishes, then the first wisp of fire energy in the world will no longer appear. Even if the other eight flame fragments combine, the resulting new flame can't control its temperature and will only keep increasing, never decreasing.

In a duel, releasing such a flame would mean directly putting the opponent to death, for this flame cannot hold back.

Therefore, to make such a flame freely adjust its temperature, Cold Fire must merge with fragments of Hot Fire. The name Hot Fire was coined by Ye Tianfan out of whim, as he didn't know what to call the high-temperature flame, so he casually named it.

However, after Ye Tianfan received this information, he felt his body no longer cold. In fact, he didn't feel any chill at all.

Ye Tianfan tried retracting the Xuanhuang Tower to see if it was truly not cold. If he still felt cold, Ye Tianfan planned to quickly re-summon the Xuanhuang Tower.

Ye Tianfan performed a spell, and the defensive shield covering his body from the Xuanhuang Tower slowly disappeared.

Once the defensive shield vanished, Ye Tianfan felt a refreshing breeze, with no hint of chill, even tempted to remove his coat.

This... really isn't cold?

Ye Tianfan looked around then swiftly summoned the Fire Lotus Sword, stepping onto it, flying towards the outside of the ice crevice, facing the gusting bone-chilling wind. He aimed to test whether he still felt cold.

However, Ye Tianfan no sooner flew out then he flew back down.

It wasn't due to the cold but because Ye Tianfan couldn't bear the strong wind. It threatened to sweep him away if he lingered.

Nonetheless, what made Ye Tianfan happy was, he didn't feel cold, merely the wind making it hard to keep his eyes open.

This outcome pleased Ye Tianfan greatly because it meant he could leave the Zero-Degree Plain and become the first person to do so.

Of course, Ye Tianfan could still feel the chilly temperature but wouldn't feel cold.

Thinking this, Ye Tianfan contentedly returned to where the Cold Fire appeared, as the whistling strong wind above temporarily prevented him from leaving.

Using the Xuanhuang Tower would rapidly deplete Ye Tianfan's spiritual power, and the fierce wind reduced visibility by blowing snow into the air. So Ye Tianfan couldn't proceed now; lacking knowledge of the way out, calm weather at least allowed straight-line movement, whereas strong winds were likely to cause circling.

Ye Tianfan took out food stored in the Xuanhuang Tower, given its long use. And since he expected to stay here longer, he decided to eat something to pass time and took out previously purchased food from inside the tower.

Yet, the instant Ye Tianfan took it out, the food, initially steaming, instantly frosted over, and before Ye Tianfan could feel the warmth of the plate, it turned icy cold.

Ye Tianfan helplessly returned the food to the tower, reasoning it was too cold to eat—just imagine breaking teeth due to the cold, quite unwise.

Ye Tianfan summoned the Fire Lotus Sword, then found two ice blocks and placed the sword upon them. He infused the sword with three techniques.

The result proved merely to make the ice blocks slippery with no other effect.

Ye Tianfan attempted placing the frosted meal on the Fire Lotus Sword, discovering the frost lingering atop, albeit less apparent this time.

Seeing this, Ye Tianfan understood the three techniques weren't sufficient to warm the food.

Ye Tianfan hesitated upon realizing this, whether to proceed with the four techniques?

But his spiritual power was inadequate, and using four techniques merely to warm food? His master would likely chase him from the Great Fire Peak to the Zero-Degree Plain with the Great Fire Sword if he found out.
