The Prison of Fire Refinement lived up to its name. Those imprisoned within it suffered as though they were trapped in a fiery hell, enduring endless torment that made life worse than death.

After learning its location, Ling Feng wasted no time and headed straight toward a hidden area in the eastern outskirts of the imperial capital.

Fortunately, he had investigated the matter beforehand. If he had stormed directly into the imperial capital's prison earlier, he would likely have found nothing.

With his current disguise, Ling Feng easily slipped past the city gates. Once outside the city, he restored his original appearance. His figure flashed as he sped toward the Prison of Fire Refinement.

After flying several hundred li, he finally sensed the temperature ahead rising to an unbearable level. Only then did he stop.

"No wonder my Boundless Vision could not locate the prison from within the city. It's far from the imperial capital."

Ling Feng frowned.

Even martial artists protected by elemental force would find such scorching conditions difficult to endure. As for the elders from Tianwei Academy and the Alchemist Guild, their cultivation had been sealed. If they remained in this dreadful place much longer, the intense heat would roast them to death before the demonic miasma poison even had time to consume them.

"I must finish this quickly!"

Ling Feng took a deep breath. This location lay far enough from the imperial capital that he no longer needed to hide. He immediately summoned the Eradicator of Realms and charged straight toward the main gate of the Prison of Fire Refinement.

"Who's there!"

The guards stationed there instantly drew their weapons when they saw someone forcing his way in. Fierce expressions filled their faces as they surrounded Ling Feng. In the blink of an eye, over a hundred guards at around the Spiritual Sea Realm closed in on him from all sides.

"That is quite the formation!"

Ling Feng pursed his lips slightly.

Within the Tianbai Empire, king-tier experts were already considered powerful figures. Yet this prison alone was guarded by more than a hundred king tier experts. It was clear how seriously Yan Jinghong regarded this place.

"Step aside. Don't force me to start killing!"

Ling Feng stood with his hands behind his back while the Eradicator of Realms rested against him. Most of these soldiers belonged to the Divine Guards and had originally served under the Cangqiong Sect. Ling Feng had no desire to slaughter them.

"Ridiculous. A brat who still smells of milk dares to boast here!"

One of the commanders stepped forward. The middle aged man had reached the level of a half step Human Emperor. After hearing Ling Feng's words, he burst into laughter.

"Men. Capture him!"

"Fool courting death!"

A cold light flashed through Ling Feng's eyes. His vitality surged through his body. In the next instant, the roar of a dragon echoed endlessly as if an ancient dragon elephant were roaring toward the heavens.

Boom!

A violent shockwave erupted outward. More than ten guards who had rushed toward him were instantly blasted away. Their protective qi shattered as they coughed up blood and crashed heavily to the ground, left crippled and half conscious.

Ling Feng had already shown mercy. If he had not held back, his Dragon-Elephant Divine Strength would have reduced them to nothing but shattered remains.

This was the gap in strength.

King-tier experts were formidable only within the Tianbai Empire. Across the entire Dongling Region, they were merely slightly stronger ants.

"Wh... what kind of power is this..."

The middle aged commander's eyelids twitched violently as terror filled his heart.

What kind of monster is this young man?

He is too strong!

Unbelievably strong!

"I will say it once more. Move aside. Otherwise you will all die!"

Ling Feng's expression turned cold. His gaze swept across the crowd like an icy blade.

Everyone felt a chill run through their bones.

They could clearly sense that killing them would take this young man no more than a single instant.

"C-Commander, what should we do?"

Cold sweat poured down one guard's forehead as he turned back toward the middle aged commander. Even his voice trembled.

"Withdraw!"

The commander clenched his fists tightly.

Fear had completely taken hold of him.

Just releasing his aura had nearly killed more than ten king-tier experts. That kind of power was far beyond anything they could resist.

Soon the guards stationed outside the Prison of Fire Refinement retreated more than a thousand zhang away. None of them dared remain any closer.

"Wise choice!"

Ling Feng's figure flashed forward as he entered the Prison of Fire Refinement.

Only after stepping inside did he realize that the prison had been built upon an earth vein.

Rivers of magma flowed everywhere through the earth vein, surging endlessly and radiating terrifying heat.

Deep within the earth vein stood a massive man made prison. Those once imprisoned here had mostly been notorious bandits or infamous demons who had once dominated their regions. Now the cells held ministers and officials who had opposed Yan Jinghong.

"Something feels wrong..."

Ling Feng narrowed his eyes as he studied the prison cells ahead. A vague sense of unease crept into his mind, though he could not identify the exact cause.

"Forget it. I will save the people first!"

His figure flashed again as he moved deeper into the prison.

With his physique and the fourth-phase Devouring Flame within him, such an environment felt almost comfortable. He experienced no discomfort at all.

Before long, Ling Feng located the prisoners held in this area.

Those locked in the outermost cells were mostly elders from the Alchemist Guild and Tianwei Academy.

"Mentor Zhu Rong! Academician Ye!"

At first glance Ling Feng recognized several familiar faces. They were elders from Tianwei Academy who had treated him well in the past.

"Li... Ling Feng?"

Ye Guichen stared in astonishment. When he first saw someone entering the prison who was not dressed as a guard, he had felt confused. The moment he recognized Ling Feng's face, shock filled his eyes.

Zhu Rong also stared at him in disbelief as he rubbed his eyes repeatedly.

"My old eyes are not playing tricks on me, are they?"

Zhu Rong's cultivation was slightly weaker than Ye Guichen's. However, he cultivated fire based martial arts and possessed a fire based physique, which allowed him to endure the heat better. As a result he looked more energetic than Ye Guichen.

Pei Miao, who had always clashed with Zhu Rong like fire and water, looked far worse. He lay on the ground barely conscious, his body shriveled as if he had been roasted dry.

"It's me!"

Ling Feng nodded.

"There is no time to explain. I will get everyone out first."

"Uh..."

Ye Guichen stared at him in shock.

"Ling Feng, how did you get in here? The elite troops of the Divine Guards are guarding outside!"

Zhu Rong looked miserable.

"You foolish boy. You walked straight into a trap. Of all places you could have gone, you chose the Prison of Fire Refinement. Stop wasting your efforts. Our cultivation has been completely sealed. Even if you break us out of these cells, the guards outside will still kill us!"

"That is right. Ling Feng, we appreciate your intentions, but you should leave us alone!"

Ye Guichen sighed.

Ling Feng was alone. There was no way he could take care of so many burdens.

"Academician Ye, listen to me."

Ling Feng spoke quickly.

"I possess a magical treasure that contains its own independent space. I can temporarily place you all inside it. Earlier I already found Vice Director Tong and the others. If you want details, you can ask Vice Director Tong once you enter that treasure. There is no time to waste. I will rescue every one of you and get you out of here!"
