The energy coursed through his entire body, instantly dispelling the chill completely.

"I wonder how efficient the Carefree Pavilion is.

"Before they arrive, I should explore what this Beast Refining Hell is all about."

Luo Lie glanced into the depths of the Beast Refining Hell.

In his memory, no one had ever ventured into the innermost layer of this place. A Heavenly Heart Realm cultivator once attempted to explore it but ended up with frostbitten internal organs, even damaging their dantian. After escaping, they barely survived. According to that Heavenly Heart Realm expert, they hadn't even reached the middle section, leading to the belief that even those at the Shattering Stage would struggle to reach the innermost layer. Since the strongest in the Northern Waters Kingdom were only at the Fate Palace Stage, the true nature and purpose of the inner layer of the Beast Refining Hell remained a mystery, though it was used as a prison for punishment.

"I'll see how far I can go."

If Luo Lie were to compete with a Heavenly Heart Realm cultivator, in terms of combat, they could kill him with just a finger.

However, he was confident in advancing a certain distance here.

His confidence lay in his physical prowess. He believed that the Heavenly Heart Realm cultivators in the Northern Waters Kingdom likely didn't have advanced techniques, resulting in average physical strength. Their ability to go so far relied on the abundant energy of the Heavenly Heart Realm.

Indeed, his energy was far inferior, but his physical strength was exceptional.

This strength was evident when he competed against Long Nu using the Man-Dragon Unity Technique, equivalent to battling a Yin-Yang Realm dragon physically, and he even had a slight advantage. Later, after refining his body with dragon blood, his internal organs developed protective qualities, further enhancing his physical condition. Naturally, he wanted to test it out.

Luo Lie strode forward.

After advancing more than ten steps, he could feel the coldness increase three to four times.

He used a tenth of his internal energy to stimulate his entire body, making his cells seem to awaken, emitting astonishing heat to resist the cold.

He continued forward.

Relying on his robust physique, and with only the meager energy of Body Refining Level Five, Luo Lie advanced nearly fifty meters deep.

The passageway had turns, with a bend every ten meters, seemingly man-made.

When you're just trying to make great content at bit.ly/3iBfjkV.

At each bend, there were chains, used to punish criminals.

Luo Lie stopped at about fifty meters, having reached his limit.

His entire energy was pushed to the limit, and with his strong body supporting him, he barely made it this far.

About seven or eight meters ahead, there were some traces left, indicating that someone had explored this far before.

"Still, I'm just a bit short."

"To say that the Body Refining Realm is only this much weaker than the Heavenly Heart Realm, it's hard to believe."

Luo Lie forgot one thing: those who came to explore were well-prepared, carrying equipment like high-temperature-releasing treasures. Without such aids, they might not have reached this depth either.

He didn't give up but began examining his surroundings.

Ahead, there was another turn, making it impossible to see what lay in the innermost part.

Luo Lie crouched down to inspect the chains frozen to the ground.

The deeper inside, the colder it became. Any object could easily be frozen, even scorching treasures couldn't withstand the prolonged cold and would eventually be encased in ice.

The difference was that other chains, though thickly frozen, were scattered outside, while the one in front of Luo Lie was partly exposed, with another part embedded in the ice wall.

Luo Lie pondered for a moment, then suddenly punched hard.

Bang! The ice wall was smashed, creating a pit with debris flying.

He turned around and struck the opposite ice wall with the same force.

Again, a pit was formed.

The difference was that the two pits, despite being subjected to the same cold and force, varied in size and depth.

The first pit Luo Lie made was half a meter deep, while the other was just over ten centimeters, a significant difference.

He looked down again at the chain embedded in the ice wall.

"Could someone have broken the chain to open a passage and escape?"

"Being locked in this place indicates extraordinary strength, and being able to think of escaping is even more remarkable."

"Since I'm idle, I might as well see if this person managed to escape."

Luo Lie unleashed a barrage of punches.

Here, with no one watching, he didn't need to hide the techniques he used with "Dragon in the Crotch."

Dragon Duel Sovereign Fist! Mountain Momentum of Heaven and Earth! He unleashed everything in a violent assault.

The area had already been breached by someone before, and though it was later frozen again by the cold, it wasn't as solid as other places and was easier to penetrate.

After over a hundred punches, Luo Lie had opened a passage over five meters deep.

Unlike the outside, the cold here didn't penetrate as easily, and the deeper he went, the easier it was to forcefully open a path.

At about thirty meters, it wasn't even that cold anymore.

Moreover, there was no ice layer.

A man-made passage truly appeared.

"My judgment was correct."

"This person was strong. Without their previous breach, severely damaging the ice, I wouldn't have been able to penetrate more than ten meters with my abilities."

Luo Lie entered the passage, which was narrow, allowing only him to move sideways with his head lowered.

It was very dark inside, so he took out a Night-Luminescent Pearl for light.

The passage was incredibly deep; he walked nearly six hundred meters without reaching the end, but it always led in one direction, suggesting it was meant for escape.

However, after over seven hundred meters, there was a sudden ninety-degree turn.

This turn, judging by the direction, led inward, toward the deepest part of the Beast Refining Hell.

"Hmm? Why didn't that person escape but instead went deeper?"

"Could it be they intended to explore the deepest secrets of the Beast Refining Hell? No, if that were the case, why break through over seven hundred meters before turning? Two or three hundred meters would have sufficed."

"Perhaps they discovered something."

With this thought, Luo Lie followed the passage around the bend.

It was still a straight line.

As he walked, he compared the direction with the Beast Refining Hell and quickly surpassed the fifty-meter depth he had reached inside.

He continued quickly along the passage.

At about one hundred thirty meters, he finally reached the end.

Here, the bone-chilling cold returned.

He found no bodies, only some blurry writing.

He used the Night-Luminescent Pearl to examine it.

The message was simple.

It was a note left by the person who opened the passage: "I was a man doomed to die, but found a glimmer of hope, seeking escape. I sensed a great mystery within the Beast Refining Hell that could bring me rebirth. I came seeking fortune, but was poisoned, and the poison is about to take my life. I leave this message for a fated person. I will use a special secret technique to force open a passage. Whether it reaches the deepest part of the Beast Refining Hell or not, my body will be gone. If it doesn't open, it won't be far. I hope the fated one will not give up and unlock the greatest secret of the Northern Waters Kingdom, perhaps gaining an unparalleled opportunity."

Further words were too blurred to read, but some seemed to express a wish for revenge, though they were destroyed by the impact of the secret technique, making them impossible to decipher.

Luo Lie couldn't help but sigh, feeling pity for this person.

They had found life in the face of death, with fortune within reach, only to die from poison.

Yet here he was, a mere Body Refining Realm cultivator, with no hope of uncovering the secrets of the Beast Refining Hell, but now finding an opportunity.
