Transmigrated with my corruption system

The silence stretched for several long seconds before one of the clan leaders could no longer contain himself.

He stepped forward aggressively, snapping at the newcomer.

"This is a meeting reserved solely for clan leaders! You dare barge in here with such impudence?!"

Raising his hand, he launched an attack the moment he saw the blue-robed figure continue to ignore him.

"Die for me!" he roared, throwing a punch at the man’s head with all his strength.

The air screeched violently, but just before the fist connected, the blue-robed man raised his arm and easily blocked the blow, clasping the fist tightly in his palm.

"Huh?" Elric grunted in surprise. The punch carried enough force to send a low D-rank flying, yet it had been stopped effortlessly. His shock deepened when he tried to pull his arm back and found he couldn’t.

What was happening? Panic flickered in his eyes. The only reason he had dared attack was because he didn’t recognize the man among the clan leaders.

Why, then, did this stranger possess such monstrous D-rank strength?

Before Elric could spiral further into fear, the blue-robed figure placed his other hand on Elric’s head.

A devastating jolt of lightning tore through his skull, frying his brain before it imploded into multiple fragments.

The man let go, allowing the headless corpse to collapse lifelessly to the ground.

"Pathetic," Thunderblade breathed, the first word he had spoken since arriving. Was this what passed for regular D-rank strength these days?

Before he could continue, two battle cries erupted from the chamber as two more figures charged at him, weapons raised.

"You dare kill a clan leader right in front of us?! We don’t care who you are, but this is the first and last mistake..."

They didn’t get to finish their threats before the blue-robed man casually waved his arm. The air around him rippled violently as spectral blades of lightning formed in an instant.

With another flick, they shot forward, tearing through both charging figures and their weapons in a single sweep. Their bodies collapsed lifelessly beside Elric’s charred corpse.

Raising his head, Thunderblade scanned the remaining clan leaders. A smile slowly spread across his face, his eyes lighting up with a blue sheen as lightning buzzed within them.

"Does anyone else want to have a go?"

Another wave of silence fell. Then faint murmurs began to spread through the hall.

"Th-this... I don’t believe it... it can’t be true..." one clan leader muttered. The bloodshed didn’t faze him, he had seen plenty of that, but the crest engraved on the newcomer’s robe did.

"That crest... I know it."

"But it’s impossible... they were wiped out."

"Well, what is it? Spit it out already!"

"It’s the Thunderstorm crest! And with that power... that would be... the patriarch... Thunderblade."

The moment the name left his lips, a wave of terror washed over the clan leaders’ faces. They knew that name all too well.

The clan that had ruled Tempest for generations... only to disappear without a trace one fateful night.

Hearing their whispers, the blue-robed man shook his head slowly, a scowl forming on his face. Were these the lies they told themselves to feel comfortable in his clan’s absence? Whatever the case, it didn’t matter now.

He noticed another clan leader stepping forward and approaching him cautiously.

Was this one about to charge as well? Thunderblade mused, already preparing another blade of lightning while snickering inwardly.

Clearly, the intelligence of these so-called clan leaders had devolved along with their power.

But before he could attack, the approaching man bowed his head slightly. A look of deep reverence burned in his eyes.

"Forgive their ignorance... they do not know who you are," he muttered, chills racing down his spine as he glanced at the three fresh corpses scattered across the floor.

Barely a few seconds, and three D-ranks had been killed as if they were nothing. Gulping audibly, he raised his head and looked at the blue-robed figure with a shaky voice.

"If I may be bold... may I ask why you have decided to show up at this time?"

Staying his hand, Thunderblade sighed quietly and gave a slight nod. It was good to see that not everyone here was completely senseless.

The question stirred old memories. The Thunderstorm House had ruled over Tempest for a long time, with no one daring to oppose them.

But as the years passed, their ambitions expanded beyond the city. To achieve true dominion, they needed absolute power. Someone who could break into the elusive C-rank.

He had entered seclusion, with his entire clan following suit, letting their name fade into the shadows.

Decades had passed, yet his goal continued to elude him. Now, reaching the end of his lifespan, he had been forced out of seclusion.

If he couldn’t break into C-rank within this short window, his fate would be sealed.

He stood at the absolute peak of D-rank—so close, yet so far. All he needed was someone strong enough to push him over that final edge... in battle.

None of the D-ranks in his own clan could even pose a challenge anymore.

He had emerged hoping these clan leaders might offer something more. But seeing them now, he could practically smell the weakness radiating from them.

If it had been any other time, his hope would have died here. But there was still one person left.

This rising star whose shadow had reached even the Thunderstorm Clan. Whose feats grew more ridiculous by the day. Maybe he could give him the push he sought.

Snickering at the bickering of these brats, Thunderblade stared at the rows of clan leaders as nothing more than weaklings. He would be long dead before they ever managed to launch any real attack against him.

It was time for a change of tactics. Ignoring the question entirely, he declared in a commanding voice:

"I shall lead this little group of...defiance you have formed. We will march to attack House Greyson tomorrow."

As his words echoed, various expressions crossed the clan leaders’ faces. Slowly, they all nodded in agreement.

Declining had never been an option. Seeing their submission, Thunderblade smiled.

All that remained... was the final act of fate.
