Chapter 679: Four Improvements

Unbearable agony, indescribable pain—simply unbearable pain…
If it weren’t for the Holy Light Hammer continuing to strike Su Che repeatedly, keeping him pinned to the ground and unable to move, he would have long been rolling around in pain.
“What’s going on? What are you doing?”
Lao He was also frantic in the Immortal Prison, utterly confused as to why the Immortal Prison Pagoda would torment its master to such an extent.
Yet the Immortal Prison Pagoda seemed indifferent, and the unbearable pain persisted.
In such a state, even a single moment felt like ten thousand years. Su Che was in extreme agony, yet strangely, his mind remained clear due to the strange chill, even preventing his usual self-protection mechanisms from functioning.
He had no choice but to endure it—there was no way to resist, as this pain came from the Immortal Prison itself.
After a full fifteen minutes, happiness suddenly arrived!
For Su Che, as long as this agony stopped, it was the greatest happiness possible.
Boom!
The pain ceased abruptly. Su Che felt light all over. His first thought was, “It’s over, I’m dead—definitely dead!”
He thought he was dead because, in that instant, he felt his head explode, shatter completely, and turn into nothingness. Without a head, how could he still feel pain?
But just a moment later, Su Che realized it wasn’t his head that had exploded—it was his mental realm that had expanded explosively, in an indescribable, almost invisible way.
It was called invisible expansion because Su Che didn’t sense any increase in his spiritual energy; it remained at its original level. At first glance, nothing seemed to have changed—the mental realm was still as it was before.
But upon closer inspection, he understood it was exactly what he had hoped for: the capacity of his mental realm had greatly increased, seemingly possessing almost infinite capacity.
A hundredfold increase in capacity—this was it!
But it wasn’t over yet. After the expansion, residual chill flowed through his meridians throughout his body and into his heart, clearly continuing its strengthening effect.
The subsequent strengthening process was no longer painful; instead, it brought a light, comfortable sensation. Compared to before, it was like heaven versus hell.

“The Immortal Prison Pagoda first expanded my mental domain, then began transforming my blood vessels, meridians, and heart…” As Su Che understood this, doubt arose in his mind: “If the Immortal Prison Pagoda has such transformative capabilities, why was it never revealed before? It only asked me to find my own ways to solve these problems.” Sensing Su Che’s thoughts, Lao He guessed, “Could it be that your determination in fighting against the Holy Light of Destruction was purely focused on the Immortal Prison, which moved it, and thus it rewarded you in return?” “Is that so?” Su Che was still somewhat uncertain. “Who knows? I’m just guessing,” muttered Lao He. “I, as its spirit vessel, am truly a failure. I have no idea what the Immortal Prison is thinking…” Boom! Boom! Boom! Boom… The Holy Light Hammer continued to strike at Su Che’s mental defenses, but now, as he underwent transformation by the cool energy of the Immortal Prison Pagoda, not only did his physical body undergo fundamental changes, but his mental state also seemed to rise sharply, making him pay less attention to the hammer’s attacks. Boom! Boom! Boom! Boom… Whether it was because Su Che’s mental defenses grew stronger or the hammer’s force weakened, whatever it was, Su Che became increasingly resilient with each strike. Eventually, he simply propped himself up on his arms, changing from a prone position to lying flat, resting comfortably there. After lasting for over an hour, the strange cool energy transmitted by the Immortal Prison Pagoda gradually ceased. Although Su Che’s cultivation level hadn’t improved at all, he could clearly sense that his mental domain, heart, internal meridians, and all blood vessels throughout his body had seen a significant boost in endurance. “Not just a hundred times—definitely much more!” Lying flat on the ground, Su Che’s mind was calm, completely ignoring the continuous attacks from the Holy Light Hammer. “Apart from these four aspects, my bones, fused from hundreds of thousands of Demon God bones, have no problem with endurance—thousands of times increase is nothing. That leaves only muscles, the Immortal Infant, and internal organs… Among these three, improving the Immortal Infant is the most difficult!” Muscles have the greatest elasticity, followed by internal organs, while the Immortal Infant has almost no elasticity, with a fixed capacity. That’s why Su Che believed improving the Immortal Infant was the most challenging.

Yet no matter how difficult it was, he was one step closer to success. Just a few blows later, it seemed as if the Immortal Prison was moved, suddenly bestowing upon him such a great gift—solving four aspects of improvement at once.
“This proves that as long as you can imagine it, you can achieve it!”
With a leap, Su Che sprang to his feet, showing no sign of injury. The blood on his body was wiped away by a dust-removing technique, leaving him full of energy.
Boom! Boom! Boom! Boom…
The Holy Light Hammer continued to strike the Gate of the Soul, but for Su Che, it was less impactful than a tickle.
The inner demons remained, but his mental endurance had increased by far more than a hundred times.
Su Che slowly opened his eyes. Inside the Holy Light Hall, the once-blinding golden light was now much softer, allowing his vision to penetrate over ten zhang. Though his field of vision was only about ten zhang, it was still far better than being blind. He looked around and finally chose a direction based on the patterns on the stone floor, then slowly moved in that direction.
His intuition was quite accurate. After walking less than a hundred zhang, he saw a large door.
Boom!
Without hesitation, Su Che stepped forward and pushed hard—the door swung open with a roar.
The golden light faded instantly. On the other side of the door, there was no more Holy Light of Destruction, only a very soft milky white light that wasn’t at all dazzling.
It seemed to be an inner hall, slightly smaller in size. In the central area, eighteen water mirrors surrounded a semi-transparent statue standing over three zhang tall.
Su Che hadn’t had time to observe the water mirrors closely yet. His first notice was that the statue’s design was extremely simple—just a rough human shape, with vague outlines for limbs and no distinct facial features. It could be described as merely having a head and face.
Seeing this statue, Su Che remembered the faceless purple jade figurine he had once obtained. It was because of that purple jade statue that the soul enslavement function on the fourth floor of the Immortal Prison appeared…
“Is this the final challenge of the Immortal Demon Battlefield?”
Su Che walked slowly toward it, sensing no danger in the inner hall.
“Master, I bet that if you succeed in this challenge and obtain the ultimate opportunity, the statue’s appearance will definitely become exactly like yours.”

Lao He said firmly, “I’m thoroughly tired of this trick. It’s nothing special at all. I’ve created quite a few such opportunities on Qiyuan Star, specifically for those young ones in the Foundation Establishment and Golden Core stages. It’s quite interesting to see their excitement after they get these opportunities…”
“The opportunities you arranged?”
“The opportunities you set aside for those young ones in Foundation Establishment…”
Unintentionally by the speaker, intentionally by the listener, Su Che suddenly realized something and immediately stopped in his tracks, remaining motionless…
