My Muscle System in the Mage World

Asmodeus voiced, "Kid, were you afraid that I will kill you?"

William's soul body trembled as he could only grit his teeth in frustration.

In the material world, after Walter took over the body of William, 'William's' blue eyes snapped open, and the boy fell to the ground with a thud.

However, ignoring the slight back pain, which could hardly be anything, a smirk graced his lips.

"I have succeeded," 'William' started to laugh loudly, already reeling in his victory. However, after he laughed for a short time, a small cracking sound of bones echoed as his body slumped to the ground.

"Eh," 'William' was stunned as he accessed his body, seeing that he couldn't access the kid's mental space; however, he had deeply studied this blood possession spell already, so he knew a thing or two.

Erasing someone's consciousness wasn't an easy task at all; it needed constant effort, regardless of the strength of the spell. Although William might only be a peak wizard apprentice, his consciousness was barely beginning to shell.

However, even with a tier three spell, he couldn't completely remove it out of existence. He could only slowly attack his consciousness and drain it over time.

However, William's body being so fickle was unexpected for Walter. He had never heard this would happen after he took over the body.

'William' slowly stood up with some effort, a frown on his face.

"This is unexpected," he said as he looked at his own hand, feeling an unbelievable lethargy deep inside him, as if his body was already ageing rapidly.

'William' narrowed his eyes with sheer astonishment.

"What is happening?" No matter how he thought about it, he couldn't understand why his body was dying so quickly, as if time seemed to accelerate within him.

"This can't be happening."

'William' dragged his body and used various methods to try to heal himself. However, no matter what he tried, his body simply couldn't heal, and the vitality within him, which kept his body intact, seemed to be fading rapidly.

"Wait, could it be because of the presence of my own soul?" A trace of helplessness appeared in 'William's' eyes as he pondered this possibility.

"This might likely be the case," he uttered in frustration. This wasn't stated in the spell when he learned it.

How could taking over someone's body be so easy?

If it were so easy, then the old monster would never die of old age.

If it were so simple, the lifespan in this world would not be heavily restricted, with practically no way to increase one's lifespan except for using the lifespan spell.

Just as Walter was grappling with one dilemma, a sense of impending doom washed over him, emanating from the depths of the mental space.

Despite the tight grip of the bloodline possession spell that locked down his mental space, a minuscule spark of light began its effortlessly penetrating, destroying the spell in one swift motion.

As the spark approached, it brought with it an aura of terror, crashing into William's already crumbling body like a relentless storm.

His form, already in a state of decay, succumbed even more rapidly to the onslaught, vitality draining away with each passing moment.

Before Walter could muster a response, the spark of light struck his phantom body with pinpoint accuracy, forcefully expelling him from the vessel he had commandeered.

He crashed to the ground with an unsettling "thud," the impact reverberating through his incorporeal form.

Meanwhile, William's now-soulless body collapsed unceremoniously, his once-bright blue eyes now dull and lifeless.

As Walter's phantom form rose from the ground, disbelief painted across his features, he was met with a chilling voice.

"Ant."

The chilling finality of that single word hung in the air as Walter's consciousness was abruptly extinguished by the relentless force of the spark of light.

In an instant, Walter ceased to exist, his phantom form vanishing without a trace. A fleeting glimpse of unwillingness flickered in his eyes, a futile resistance against the inevitable fate that had befallen him.

But against the cold, indifferent voice that had pronounced his demise, Walter was powerless.

With Walter eradicated from existence, the spark of light remained unperturbed, its task completed without a hint of remorse. It lingered momentarily, as if to savor its victory over the now-vanquished tier two wizard.

Then, without hesitation, it returned to William's body, retracing its path back into the mental space. Passing through the golden text, it found its way back to Asmodeus' form.

Meanwhile, Lily surveyed the situation with a comprehensive gaze, her thoughts swirling as she consulted with her elder sister and the other imprisoned souls within the holy book.

Asmodeus spoke again.

"Alright, kid, I eliminated the ant for you. You can take back your own body now," Asmodeus declared, his voice carrying a hint of satisfaction.

William's eyes lit up with excitement as he hurriedly closed his eyes and focused on reclaiming control of his body.

When he opened his eyes, he found himself staring at a gleaming metal ceiling illuminated by a soft light.

"I am bac-" His words were cut short as searing pain erupted throughout his body, causing him to collapse to the floor, clutching his head in agony.

Internal injuries racked his body, each movement sending waves of pain coursing through him. But the worst of it all was the thinness of his vitality, barely enough to sustain his own existence.

"Ahhh!" William cried out, his eyes losing their spark as his body began to crumble under the strain.

Inside his mental space, Asmodeus smirked at the sight.

"Hehe, my plan is going well."

As if in response to Asmodeus's machinations, the golden text within William's mental space began to shine with a lustrous golden light.

A beam of light shot out, instantly enveloping William's form and beginning the process of healing his injuries, restoring him to his previous state of health.

However, the bright golden light dimmed slightly because of it.

The chains around Asmodeus and the holy book both loosened slightly in change.

William, unaware of this, opened his eyes slowly, standing up from the ground.

"I healed already," his body was back to its optimal state that he was previously in.

"Is this golden text, allowing my life to be protected?" William thought as a realisation hit him.

He didn't need to beg for Asmodeus at all. As long as he died, the golden text would return him to his previously optimal state as if reversing time itself.
