Reincarnated as the Demon King's Son

"Master!"

"Elfie, how long have you been waiting?" Tom was quite shocked to see Elfie here.

"I waited the whole day, master."

"The whole day? What are you talking about? It's been months."

"Months… Master, are you perhaps been inside the tower for months?"

"Yeah. It feels like forever already."

"That is normal. The Spiritbound Tower is not bound by space nor time. It is bound by the spirit of its owner, and they can manipulate time and space however to the owner's wish."

Tom frowned. "Can it affect space and time outside the tower?"

"To a certain extent, yes. It is a very powerful treasure. From what I know, only Adamantite Ranks supposedly have these kind of treasure."

"I see. Anyway, I need to return for now."

"What are you going to do, master?"

Tom flicked his hand and a thick scroll appeared. "I need to learn this skill."

[Scroll of Beastly Rip (Legendary)]

Transforming mana nearby into its most chaotic and violence nature, enabling the user to rip apart objects and even space itself.

Elfie's eyes widened in disbelief. "Master, you shouldn't show that scroll so lightly. Please quickly hide it."

Tom immediately put it in his inventory. "I will be fine. You worry too much, Elfie."

"Master, that is a legendary skill. It cannot be bought at all. It never even appear in auctions after thousands of years. Did miss Claudia gave you that? If that is the case you should safely keep it."

"You underestimate me, Elfie. I am the son of Aldred. His army has spread far and wide. Who would dare to fight me? Hahaha!"

"Master, a lot of people are willing to kill for a simple Epic-class skill. Not to mention a legendary skill. Please be very careful."

"Alright. Come on, let's go back to the mansion."

"A legendary skill… did Claudia really gave him that?" A teacher exclaimed in the secret room.

"Claudia is serious about him. She really consider him to be her personal student."

"Just what has happened inside the tower for Claudia to give him a legendary skill?"

"I am not sure, but it has to be something profound."

"I don't blame her. Tom manage to pass the Spiritbound Tower test that only high Diamond Rank prodigies manage to reach. He is an anomaly among anomalies. His talent might only be found every 100,000 years."

"But learning a legendary skill could take years. Most learn it in decades. I think it's too soon for him to get a legendary skill."

Everyone looked at the teacher who said that.

"Moroud, don't even think about it. Tom is protected by Claudia and possibly the Axbrid family. Not to mention his father is a controversial figure right now. I also heard that he is very protective of his son. If you tried to take that legendary skill away from him, we don't want to handle the consequences."

"You're thinking too deep. I am just saying that he need to grow first before he could properly learn that skill. As for stealing the legendary skill, I am not foolish enough to do that."

…

At night, Tom was walking side by side with Elfie.

"Master, why don't we just teleport to the mansion?"

"I want to enjoy the moment."

"I… I see."

Tom's lips curled into a smile. "There they are."

"Huh?" Elfie was confused.

Ten shadow figures jumped out of the trees and landed on the ground. The ten of them were wearing black clothes and black mask that fully covered their body.

"How did they get in here? This area is fully monitored and protected."

Tom laughed. "It's an inside job. Step back, Elfie. I will take care of this."

Tom intentionally reveal the legendary skill to lure a high Diamond Rank to attack him. This way, he could kill them and get an extra high Diamond Rank undead. But what he saw disappointed him. Instead of a high Diamond Rank, they send ten mid Diamond Rank.

"Haish… why do they send 10 losers to fight me."

The ten thieves were quite enraged to hear that word from Tom. All of them moved in a flash, pulling out a small dagger out of thin air and jumped at him.

"Oh, you guys are as slow as snails."

Tom rushed forward, then suddenly appeared in front of one of the thieves.

The thief widened his eyes in shock, but his hand reacted, gripping the blade tight, and stabbed towards Tom.

Tom slapped his hand away with a wide smile on his face. "Tell your master to send someone stronger next time!"

Tom kicked the man's balls in mid air, crushing them instantly. The man screeched in pain before Tom spun in the air, his leg came from above and slammed the man on the head, sending him crashing to the ground.

'One down, nine to go.'

Two thieves sprinted at him. The dagged in their hand glowed a dark blue light and killing intent locked in towards Tom.

Tom turned around and grabbed their wrist, the tip of the blade stopped right in front of his face.

Sudddenly, the tip of the blade revealed a hole and a needle shot out.

Tom blew. The powerful wind coming out of his mouth knocked the needles away.

He then tightened his grip on the two men and then pulled, snapping their wrist.

"Ahh!"

As they screamed, Tom beheaded them, ending their scream in an instant.

Their bodies fell to the hard pavement and blood dripped from Tom's nails. He did not use his sword to behead the two thieves which made it even scarier.

'Three down, seven to go.'

The rest of the thieves gulped as they hesitated to attack.

"I pitied you all," Tom said. "Whoever send you here are sending you to your death. There is no chance for you to harm me."

Tom summoned his Phantom Doomblade, then he vanished from the spot, shocking the thieves.

"I am right behind you."

Before they could turn around, Tom slashed in a wide arc. The Phantom Doomblade was in its long and thin form, edged sharp on both sides. Tom swept it out, carving a line of dark-red energy in the air as the blade cut three thieves in half.

"Four to go."

"What are you?" One of the thieves asked as he took a step back.

Tom appeared in front of him, raising the blade above his head as he stared into the man's eyes. "I am death."

He slashed the sword downward and the man was split into two.

"Three left." Tom turned around before he swung the sword to the side, slapping the blood to the ground.

Elfie watched this scene in silence. She finally get to see how Tom fight. It was brutal and terrifying style of fighting.

The three thieves flashed away in different directions.

"You cannot escape from me!" Tom swung his blade, a golden thread came out of the tip of the blade, decapitating two thieves at once.

Tom turned around about to attack the last thief until he saw that Elfie was captured.

"Let me go, or I will kill this woman." The thief had his dagger on Elfie's neck.

"Ignore me master, just kill him."

Tom had a bright future ahead of him. Not only was he extremely talented, he also had miss Claudia behind his back. Meanwhile, Elfie was just a maid. Her position was nothing important, and she had no future after this.

Tom sighed and transformed his Phantom Doomblade into a sniper.

BANG!

Then fired it accurately at the thief's head, exploding it like watermelon. Blood splashed all over.

Elfie turned around and saw the headless corpse fell.

"That was a good workout," Tom said.

"Master, thank you for saving me." Elfie bowed.

"Don't mention it. Let's go. The mansion is near."

Elfie nodded and stepped over the corpse before she walked beside Tom.

An old man in his sixties, yet had an athletic figure walked on the rooftop. He was tall with and pale with grey hair and barely any wrinkles.

He stopped beside a beautiful woman and looked towards the distance.

"That boy is growing strong."

The old man turned to look at the woman. "Are you still insisting on helping him, princess Vel— miss Claudia."

"There is no reason to stop now."

"Your father might not like this."

"That's because he doesn't see what I see. Once he does, he will let me do whatever I want."

"There are people watching him," the old man said.

"Kill some of them as warning."

"Even the teachers?"

Claudia frowned slightly. "Let them live."

"Certainly."

That night, thousands of scream was heard in the capital city of Withokere. Blood filled the street as people randomly died at night. What was weird was that all of them were at the level of high Diamond Rank.

This phenomena shocked the people, but for the people above, they knew it was a warning.

A deadly one.
