My Muscle System in the Mage World

Chapter 31: Holy Magic Book

William thought, his back soaked in cold sweat, "Is that guy still inside?" His eyes flashed with a dark aura as he carefully looked at the ground again, seeing three footprints going inside the cave; however, only two footprints came outside.

"No, I must go. I need strength to take my revenge." In William's eyes, a flame of vengeance burned as he advanced, witnessing the gruesome sight of the wolf's mangled body along the way, all ploughed down with what seemed like a blunt weapon without mercy.

"This is really..." The disgusting stench of death made his nose twitch as his skin crawled.

With a disappointed expression, he reached the mine where there was a single quartz shining its bright light around its surroundings.

"All things have been dug out except these..." William muttered in disappointment as he looked at the uneven walls where he could find traces of being brute forced.

"Whoever had come, they were a brute man." He sweated with a sigh of relief not seeing anyone till now.

Rumble!

The ground seemed to rumble slowly, as if an earthquake occurred, and a door opened, revealing a dark passageway.

William's eyes narrowed as he walked towards it without hesitation.

...

"That feeling is getting closer." Inside the mental space, the golden text glinted as a shadow of a man was faintly seen from it.

However, the shadow seemed to have grown wearier and wearier. It no longer had a smug expression; instead, the shadow's face was contorted in a strange shape, as if it were frowning.

...

William finally reached the door that Aur had previously reached, the metallic, huge door.

"Come."

A soothing voice rang in William's ears, making his mind calm and peaceful. He had a hypnotised expression, just like Aur's. However, Aur was only hypnotised when he opened the door; while he was outside the room, Aur was unaffected while William was affected in just being closed to the door.

William's consciousness just couldn't resist the voice that rang in his ears like a melody. With a zombie-like walk, he approached the door and pushed it open.

Boom!

The instant he opened the door, a blinding light pierced his eyes. However, the zombie-like William didn't seem to care. Even when his blue eyes burned from the intense light, he continued to walk towards the book that was emitting a blinking light.

As he walked towards the book that shined with blinding light, the golden text in his mental space started to shine, sending a golden light penetrating the mental space directly into his consciousness.

William's eyes violently opened at that moment. He looked around in confusion, only to close them again due to the blinding light.

"What is this?" William thought, shock written all over his face.

But he was truly helpless against the blinding light that impaired his vision, preventing him from looking around.

"Tier one: true pupils."

The pattern at the centre of his mental space started to shine, making his blue pupils enveloped in a dark aura.

"Damn it, I am running out of mana already..." William cursed as he finally managed to open his eyes as the light could no longer affect him.

When he looked around the room, he was stunned to see a book floating in mid-air, shining in a golden light.

"What is this?" a question mark appeared on his face as he carefully scrutinised the book.

HOLY MAGIC!

"Finally, I found a worthy master."

The book jumped up and down in joy.

"You can talk?" William said, still in shock.

"Of course, I can talk. Please, master, as long as you touch me, I will forever be yours," the voice was sultry as it resounded from the book itself.

"You can't take it; your vital spell is already a dark spell. It will contradict with it if you take the holy magic," the cold voice rang in his ears.

"What if I take it?" William smirked.

"Then it is your choice, but if you try to inscribe a holy spell, it will contradict your dark spell and make your spell weaker and even get your body injured."

"Hmm..." William frowned when he heard this; however, he didn't stop his movement as he walked towards it without any hesitation.

"Wait, what are you doing..."

He ignored the cold tone that rang in his head as he touched the book.

The book's light dimmed as the hovering book fell into William's hand.

However, the moment William touched the book, a scalding pain scalded his hand with a sizzling sound of his hand burning.

Ahhh!

William screamed loudly as he hurriedly let go of the book. He looked at his own hand, which was red from the heat.

"This..." his eyes widened with shock.

"I told you the holy magic book isn't made for you," the cold voice rang in his head, tinged with mockery.

However, under the stunned gaze of William, the book suddenly floated up.

"Master, there is a devil residing in your body. Can I have your permission to kill it?"

"Inside my body?" William was stunned as he heard this. "I guess it is talking about Asmodeus, huh..." he mused to himself.

"Can you do it?"

"Yes, master, I can since we have bonded together as you have touched me. I can enter your mental space and kill that devil and even remove that disgusting evil spell you have cultivated." The book's tone was filled with disgust, especially in the last part.

"Oh, if you can, then do it." A smirk appeared on William's face.

"Thank you, master." The book jumped up and down in joy as it narrowed to a small size.

Boom!

The book suddenly shot towards the forehead of Williams, a streak of radiant energy trailing behind it, and passed through his head as if it were a phantom.

Buzz! Buzz!

A peculiar buzzing noise resonated in his head as the book traversed the dimensions, seamlessly transitioning from the physical world to William's mental space.

William's pupils violently shifted, their focus gradually sinking, rolling backwards.

His body seemed to experience a sudden convulsion.

After a short time, his body convulsed further and froze, and Williams became motionless.

Thud!

He fell to the ground, eyes wide open with his blue pupils rolled back.
